However, according to the international rules of nomenclature, the binomial name Foeniculum vulgare was not validly published by Hill in his reference [1] for the reason that he did not consistently adopt the binomial system of nomenclature. In accordance with the international rules as adopted at Cambridge, the name Foeniculum vulgare must be accredited to Philip Miller, who first validly published it in the eighth edition of his “Gardeners Dictionary” in 1768. From then on, the name of this plant is written as Foeniculum vulgare Mill. It is a medicinal plant belonging to the Umbelliferae (Apiaceae) family, known and used by humans since antiquity, due to its flavor. It was cultivated in almost every country [2]. It is universally known as Fennel and is known by more than 100 names (Table 1). It is a traditional and popular herb with a long history of use as a medicine. A series of studies showed that F. vulgare effec- tively controls numerous infectious disorders of bacterial, fungal, viral, mycobacterium, and protozoal origin [37]. It has antioxidant, antitumor, chemopreventive, cytoprotective, hepatoprotective, hypoglycemic, and oestrogenic activities [812]. Some of the publications stated that F. vulgare has a special kind of memory-enhancing effect and can reduce stress [13]. Animal experiments and limited clinical trials suggest that chronic use of F. vulgare is not harmful.

They are greenish-yellow the colour of hay from which theterm fennel is derived Wild fruits are short dark colouredand blunt at their ends and have a less agreeable flavourand odour than those of sweet fennel Seeds ripen fromSeptember to October This plant can reproduce from crownor root fragments but freely reproduces from seed

13 Chemical Composition and Nutritional Value of FennelFoeniculum vulgare is widely grown for its edible fruit orseeds These are sweet and dry a fully ripe specimen isan exquisite fruit The fruit is often dried for later use andthis dried fruit called fennel is a major item of commerceTable 2 lists the nutrient composition of fennel (USDA data)Fennels are one of the highest plant sources of potassiumsodium phosphorus and calcium According to USDA datafor the Mission variety fennels are richest in dietary fiberand vitamins relative to human needs They have smalleramounts of many other nutrients

Table 3 summarizes the chemical composition andthe nutritional value [14] of different parts of fennelnamely shoots leaves stems and inflorescence Leavesand stems show the highest moisture content (7636 and7746 g100 g resp) while inflorescence exhibits the lowestcontent (7131 g100 g) Carbohydrates are the most abundantmacronutrients in all the parts and range from 1844 to2282 g100 g Proteins reducing sugars and fats are theless abundant macronutrients proteins varied between108 g100 g in stems and 137 g100 g in inflorescences Theinflorescences and stems revealed the highest fat content(128 g100 g) and reducing sugar content (149 g100 g)respectively amongst all the parts of fennel On the basisof the proximate analysis it can be calculated that a freshportion of 100 g of these parts yields on average 94Kcal of

energy The highest values were obtained for inflorescenceswhile leaves and stems gave the lowest energy contribution

About twenty-one fatty acids were identified and quanti-fied from the abovementioned parts of fennel (Table 3)Theseare caproic acid caprylic acid capric acid undecanoic acidlauric acid myristic acid myristoleic acid pentadecanoicacid palmitic acid heptadecanoic acid stearic acid oleicacid linoleic acid 120572-linolenic acid arachidic acid eicosanoicacid cis-1114-eicosadienoic acid cis-111417-eicosatrienoicacid + heneicosanoic acid behenic acid tricosanoic acidand lignoceric acid Thus Barros and his coworker concludepolyunsaturated fatty acids (PUFA) to be the main groupof fatty acids present in all the fennel parts On the otherhand Vardavas and his coworker reported monounsaturatedfatty acids (MUFA) as the main group of fatty acids infennel [22] Nevertheless unsaturated fatty acids (UFA) rangefrom 66 to 80 and predominate over saturated fatty acids[14] The highest concentration of n-3 fatty acids was foundin fennel leaves while the lowest concentration was found

in inflorescences The ratio of 1205966 to 1205963 fatty acids has animportant role in the human diet The highest levels of n-3fatty acids found in leaves contributed to its lowest ratio of1205966 to 1205963 fatty acids The lowest levels of n-3 fatty acids foundin inflorescences contributed to its highest ratio of 1205966 to 1205963fatty acids

Fennels have smaller amounts of many other nutrientsOn a weight basis fennels contain more calcium (49mg100 g) as compared with apples (714mg100 g) bananas(388mg100 g) dates (250mg100 g) grapes (1086mg100 g) orange (4025mg100 g) prunes (180mg100 g) rais-ins (400mg100 g) and strawberries (1401mg100 g) Phe-nolics are an important constituent of fruit quality becauseof their contribution to the taste colour and nutritionalproperties of fruit Amongst the phenolics analyzed in thefruit of this plant are neochlorogenic acid (140) chloro-genic acid (298) gallic acid (0169) chlorogenic acid(6873) caffeic acid (2960) p-coumaric acid (4325)ferulic acid-7-o-glucoside (5223) quercetin-7-o-glucoside

32 Flavonoids Flavonoids are generally considered as animportant category of antioxidants in the human dietFlavonoids are abundant in the plants of Apiaceae family Ithas been reported that the presence of flavonol glycosidesin fennel species is related to its morphological hetero-geneity and variation Total flavonoid content of hydroal-coholic extracts is about 123 plusmn 018mgg Flavonoids likeeriodictyol-7-rutinoside quercetin-3-rutinoside and ros-marinic acid have been isolated from F vulgare [65]Amongst the flavonoids present in F vulgare the most preva-lent are quercetin-3-glucuronide isoquercitrin quercetin-3-arabinoside kaempferol-3-glucuronide and kaempferol-3-arabinoside and isorhamnetin glucoside [66] Quercetin-3-O-galactoside kaempferol-3-O-rutinoside and kaempferol-3-O-glucoside have also been reported to occur in the aque-ous extract of F vulgare [67] The flavonoids like isorham-netin 3-O-120572-rhamnoside quercetin and kaempferol werealso isolated from the ethyl acetate extract whereas quercetin3-O-rutinoside kaempferol 3-O-rutinoside and quercetin3-O-120573-glucoside were isolated from the methanol extractThese flavonoids exhibit remarkable antinociceptive and anti-inflammatory activity [68] Further quercetin rutin andisoquercitrin were reported to have the immunomodulatoryactivities [69]

33 Phenolic Compounds There has been a growing interestin phenolic components of fruits and vegetables which maypromote human health or lower the risk of disease Aqueous

extract of fennel fruits are rich in phenolic compoundsMany of them have antioxidant activities and hepatopro-tective properties The phenolic compounds present in Fvulgare are considered to be associated with the preventionof diseases possibly induced by oxidative stress such ascardiovascular diseases cancer and inflammation Thesephenolic compounds have received tremendous attentionamong nutritionists food scientists and consumers dueto their role in human health Fennel has been reportedto contain hydroxyl cinnamic acid derivatives flavonoidglycosides and flavonoid aglycones [67] The methanolicextract of fennel seeds contains rosmarinic acid chlorogenicacids as major phenolic compounds (149 and 68 resp)and quercetin and apigenin as themajor flavonoids (171 and125 resp) Also the total phenolic compounds in fennelmethanol extract were higher than the flavonoid compounds[23] F vulgare has been reported to contain phenolic acidslike 3-O-caffeoylquinic acid 4-O-caffeoylquinic acid 5-O-caffeoylquinic acid 13-O-di-caffeoylquinic acid 14-O-di-caffeoylquinic acid and 15-O-di-caffeoylquinic acid [65]Two compounds A and B were isolated and character-ized for the first time from the wild fennel and identi-fied as 34-dihydroxyphenethylalchohol-6-O-caffeoyl-120573-D-glucopyranoside and 3101584081015840-binaringenin respectively Thetotal phenolic and flavonoid contents ofwild fennel (24 and12 resp) were less as compared to cultivated fennel (31and 16 resp) [70]

chloride crude extract of F vulgare [101] suggested thatthe crude extract containing monoterpenes could be a newmedicinal resource for antibacterial agents

A total of 78 compounds were identified from theactive antimycobacterial fraction of F vulgare with thehelp of gas chromatography-mass spectra (GC-MS) Outof these twenty compounds were tested against one sensi-tive and three MDR strains of Mycobacterium tuberculosisusing the Alamar Blue microassay Compounds that showedsome degree of antimycobacterial activity against all strainstested were the following linoleic acid (MIC 100 120583gmL)oleic acid (MIC 100 120583gmL) 13-benzenediol (MIC 100ndash200120583gmL) undecanal (MIC 50ndash200120583gmL) and 24-undecadienal (MIC 25ndash50120583gmL) 24-Undecadienal wasthe most active compound against multidrug resistant Mtuberculosis speciesThus the dietary intake of F vulgaremaylower the risk ofM tuberculosis infection [63]

Orhan et al [5] studied the antiviral activity of theessential oil of fruit sample of F vulgare along with 12other Turkish medicinal plants against the DNA virusHerpessimplex type-1 (HSV-1) and the RNA virus parainfluenzatype-3 (PI-3) Most of the oils and compounds displayedstrong antiviral effects against HSV-1 ranging between 08and 0025 120583gmL However the samples tested were lesseffective against PI-3 with results ranging between 16 and02 120583gmL Only the essential oils of Anethum graveolensFoeniculum vulgare (fully mature) Mentha piperita Menthaspicata Ocimum minutiflorum Ocimum vulgaris and Sat-ureja cuneifolia inhibited this virus significantly

All these literature findings validated the traditional usesof Foeniculum vulgare in infectious disorders like abdomi-nal pains antiemetic arthritis conjunctivitis constipationdepurative diarrhea dieresis fever flatulence gastralgia gas-tritis insomnia irritable colon mouth ulcer stomachacherespiratory disorders skin diseases and so forth There isalways a need for new antimicrobial agents due to rapiddevelopment of resistance Bioactive metabolites of F vulgaremay be a potential source for new antimicrobial agents

42 Anti-Inflammatory Activity Oral administration ofmethanol extract of F vulgare fruit to rat and mice exhibitedinhibitory effects against acute and subacute inflammatorydiseases The anti-inflammatory activity of methanol extractwas evaluated by using three screening protocols namelycarrageenan-induced paw edema arachidonic acid-inducedear edema and formaldehyde-induced arthritis Theseare widely used for testing nonsteroidal anti-inflammatorydrugs For acute inflammationmethanol extract (200mgkg)exhibits significant inhibition of paw edema (69) inducedby carrageenan injection as compared to the control groupof animals Methanol extract of F vulgare also inhibitsear-edema (70) induced by arachidonic acid in mice Thelevel of serum transaminase aspartate aminotransferase(AST) and alanine aminotransferase (ALT) significantlyincreases in the presence of methanolic extract of F vulgareon inflammation induced by formaldehyde as comparedto control group The assessment of the level of AST and

ALT provides a good and simple tool to measure the anti-inflammatory activity of the target compounds [102] Theseoverall results seem to suggest that F vulgare FME mayact on both the cyclooxygenase and lipoxygenase pathways[79]

43 Antiallergic Activity Methanolic extract of F vulgarefruit showed significant inhibitory effect on DNFB- (24-dinitrofluorobenzene-) induced delayed type hypersensitiv-ity after oral administration of 200mgkg once a day for7 days The inhibitory effect on immunologically inducedswelling suggests the possible immunosuppressive propertiesof F vulgare [79]

44 Hepatoprotective Activity Essential oil of F vulgareseeds revealed a potent hepatoprotective effect against acutehepatotoxicity produced by carbon tetrachloride in ratsOral administration of F vulgare essential oil decreases thelevels of serum aspartate aminotransferase (AST) alanineaminotransferase (ALT) alkaline phosphatase (ALP) andbilirubin as compared to the control group Ozbek et alsuggest that the constituents (d-limonene and 120573-myrcene) ofessential oil may have played a key role in the protection ofliver from CCl

4toxicity [9]

45 Anxiolytic Activity Anxiety is the unpleasant feeling offear and concern When anxiety becomes excessive it maybe considered as an anxiety disorder Anxiolytic fennel isa drug used for the treatment of anxiety and its relatedpsychological and physical symptoms Naga Kishore et al[89] investigated the anxiolytic activity of ethanolic extract ofF vulgare fruit with the help of elevated plus maze rota rodopen field test and whole board models The 100 to 200mgdose of extract per kg of body weight of animal revealedsignificant activity when compared to reference anxiolyticdrug called diazepam (1mgkg) Thus fennel extract maypossess anxiolytic activity supporting its traditional claimabout anxiolytic activity reported in 19th edition of Pharma-cology and Pharmacotherapeutics by Sathodkar Bhandarkarand Rege

46 Antistress Activity Drug and food of natural originplay a significant role in public healthcare systems and arebeing investigated as remedies for a number of stress-relateddisorders [103]Thewhole plant extract of F vulgare exhibitednotable antistress effect against stress induced by forcefulswimming of test animals The key parameters that isurinary levels of vanillyl mandelic acid (VMA) and ascorbicacid in rats were used to evaluate antistress activity Theplant extract (50 100 and 200mgkg body weight) showeda significant improvement in urinary levels of VMA (119875 lt0001) and ascorbic acid excretion levels (119875 lt 0001) in testanimals when compared to the normal basal levels in controlgroup of animalsThus the extract of entire plant of F vulgareacts as an antistress agent [13]

47 Memory-Enhancing Property There are a number ofplants whose consumption is believed to enhance memory

22 BioMed Research International

and intelligence These were usually given to children as partof their food F vulgaris an ayurvedic rasayana (mixture)possessing multiple neuropharmacological activities Theantidepressant activity of fennel has been well documentedin ethnomedicine The whole plants extract (50 100 and200mgkg) of F vulgare exhibited memory-enhancing effectagainst scopolamine-induced amnesic rats This experimentwas evaluated by conditioned avoidance response (CAR)technique The CAR of rats administered with the extractincreased gradually to 95 over 7 to 12 days The acquisition(time to achieve 95 CAR) for rats administered with theextract was dose- and time-dependent compared to controlgroup which took 12 days for acquisition The percentavoidance was always higher in the extract-treated groupsas compared to control group Animals receiving 200mgkgbody weight of the extract took ten days while groups treatedwith 100 and 50mgkg doses of the extract required elevenand twelve days respectively to reach the point of acquisitionAdministration of scopolamine produced amnesia as seenfrom reduction in the observed CAR Amnesia was greaterin the control group than in extract-treated groups How-ever continued treatment with F vulgare produced betterretention and recovery in a dose-dependent manner thanthe vehicle-treated animals Recovery from scopolamine-induced amnesia in the extract-treated groups took 3ndash5 dayswhen compared to normal (control) group which took over6 days This overall progress suggests that F vulgare extractpossesses memory-enhancing property [13]

48 Nootropic Activity Alzheimerrsquos disease is a neurode-generative disorder associated with a decline in cognitiveabilities Dementia is one of the age-related mental problemsand a characteristic symptom of Alzheimerrsquos disease Thereis some evidence in favor of use of F vulgare for the treat-ment of cognitive disorders like dementia and Alzheimerrsquosdisease Methanol extract of the whole plant of F vul-gare administered for eight successive days ameliorated theamnesic effect of scopolamine and aging-induced memorydeficits inmiceThis extract increased step-down latency andacetylcholinesterase inhibition in mice significantly Thus Fvulgaremay be employed in treatment of cognitive disorderssuch as dementia and Alzheimerrsquos disease as a nootropic andanticholinesterase agent [80]

49 Antihirsutism Activity Idiopathic hirsutism is definedas the occurrence of excessive male pattern hair growth inwomen who have a normal ovulatory menstrual cycle andnormal levels of serum androgens It may be a disorder ofperipheral androgen metabolism Traditionally Foeniculumvulgare has been used as an estrogenic agent It has beenreputed to increase milk secretion promote menstruationfacilitate birth and increase libido On considering aboveaspect Javidnia and his research team evaluated the antihir-sutism activity of ethanolic extract of F vulgare seed againstidiopathic hirsutism by preparing cream containing 1 and 2of fennel extract The efficacy of treatment with the creamcontaining 2 fennel is better than the cream containing 1fennel and these two were more potent than placebo (control

group) The mean values of hair diameter reduction were78 183 and minus05 for patients receiving the creamscontaining 1 2 and 0 (placebo) respectively [78]

410 Estrogenic Properties Since the discovery of the estrusinducing effects of some plant products in 1926 consider-able effort has been devoted towards the characterizationof phytoestrogens including flavonoids isoflavonoids chal-cones coumestans stilbenes lignans saponins and essentialoils [16] F vulgare has estrogen-like activity In male ratstotal concentration of protein was found to be significantlydecreased in testes and in vasa deferentia whereas increasedin seminal vesicles and in prostate gland On the otherhand simultaneous decrease in the activities of acid andalkaline phosphatase in all these regions (except that alka-line phosphatase was unchanged in vasa) due to the oraladministration of acetone extract of F vulgare fruit wasobserved In female rats oral administration of the extract for10 days led to vaginal cornification and oestrus cycle [8] Totalconcentration of nucleic acids and protein as well as the organweights increased in both the tissues namely mammaryglands and oviducts due to the oral administration of acetoneextract (50 150 and 250120583g100 g body wt) of F vulgare seeds[104] Fennel oil was reported to exhibit estrogenic activitypromote menstruation and alleviate the symptoms of femaleclimacteric and increase libido [71] Administration of fenneloil (25 and 50 120583gmL final concentration in the organ bath)failed to exhibit any remarkable effect in uterine contrac-tion While 10 20 and 40 120583gml concentration of fennel oilrevealed significant inhibitory effect against prostaglandinE2 Fennel oil significantly reduces the frequency of uterinecontraction induced by prostaglandin E2 Thus the extractsof F vulgare have strong estrogenic activity [76]

411 Galactogenic Activity Foeniculum vulgare has been usedformillennia to increasemilk secretion [105]Thus F vulgarebelongs to galactagogue substance Structural similarity ofits main constituent anethole to dopamine seems to beresponsible for galactogenic activityDopamine acts to inhibitthe secretion of the milk-producing hormone prolactinAnethole might influence milk secretion by competing withdopamine at the appropriate receptor sites thereby inhibitingthe antisecretory action of dopamine on prolactin [71] It wasreported that anol (demethylated anethole) causes growthof the lobule-alveolar system in the mammary glands ofimmature female rabbits and induces menstruation in miceand other experimental animals Anol also gave positiveresults in the Jadassohn nipple test a test which involvesthe measurement of changes induced in the nipples ofguinea pigs subjected to the cutaneous application of sexhormones However further research suggests that the actualpharmacologically active agents responsible for galactogenicactivity are polymers of anethole such as dianethole andphotoanethole rather than anol or anethole itself [20 76]

412 Expectorant Activity F vulgare seeds stimulate theciliary motility of the respiratory apparatus and enhance the

BioMed Research International 23

external transport of extraneous corpuscles This action sug-gests a use for fennel in treating bronchial and bronchopul-monary afflictions and in particularly polluted environments[106] The volatile oil of F vulgare stimulates the contractionof the smooth muscles of the trachea an action that couldfacilitate the expectoration of mucus bacteria and othercorpuscles extraneous to the respiratory tracts [74]

413 Anticolitic Activity Essential oil of fennel regulates themotility of smooth muscles of the intestine while at thesame time reducing intestinal gas Alone or combined withother plant medicinals Foeniculum vulgare is indicated in thetreatment of spastic gastrointestinal disturbances in someforms of chronic colitis (which resist other treatments) indyspepsias from gastrointestinal atony in dyspepsias withthe sensation of heaviness in the stomach and so forthTheaddition of fennel to preparations containing anthraquinoniccomponents reduces the occurrence of abdominal pain oftenassociated with this type of laxative [73]

414 Antinociceptive Activity Antinociceptive means anysubstance that inhibits nociception which is a physiologicalprocess underlying the sensation of pain Briefly it reducesthe sensitivity to painful stimuli The various extracts ofaerial part of F vulgare namely hexane methylene chlorideethyl acetate and methanolic extract showed remarkableantinociceptive activity against acetic acid induced writhingin mice [68] The methanolic extract of the aerial parts ofF vulgare exhibited the highest antinociceptive activity at adose level of 2000mgkg while the activity exhibited by theethyl acetate extract was at dose level 800mgkgOn the otherhand n-hexane extract (700mgkg) and methylene chlorideextract (500mgkg) exhibited similar antinociceptive activi-ties being less than peripheral antinociceptive reference drug(acetyl salicylic acid) [68]

415 Diuretic Activity A diuretic is any substance thatpromotes the production of urine Briefly it is an agentthat promotes diuresis Diuretics work by promoting theexpulsion of urine (measured as the urine volume [UV]excreted) and urinary sodium (UNa) from the body and thishelps reduce the volume of blood circulating through thecardiovascular system Caceres et al [107] performed a studyin conscious animals and administered a powdered extractof the whole plant (F vulgare) which had no effect on UVor UNa The ethanolic extract of F vulgare fruit revealedexcellent diuretic activity and proves the earlier folk claimof F vulgare which was reported in the United State ofAmerica (Table 5) The fruit extract showed statistically ahighly significant diuretic effect F vulgare induced diuresis(500mgkg dose)was comparable to that of reference diureticagent urea (960mgkg dose) in mice with a urine outputthat was almost double that of the control group Thediuresis was not associated with changes in sodium andorpotassium excretion [108] In another part of the study theauthors showed that Foeniculum vulgare had little effect onthe noradrenalin contractile responses of aortic rings thus

suggesting that it worked mainly as a diuretic and natriureticwith little effect on arterial vascular tone [77]

416 Cardiovascular Activity An aqueous extract of F vul-gare leaves possesses potential cardiovascular action Thiseffect was investigated using pentobarbital-anaesthetisedmale albino Sprague-Dawley rats [75] An intravenousadministration of the lyophilized boiled water extract ofleaves produced a significant dose-related reduction in arte-rial blood pressure without affecting the heart rate or respi-ratory rate On the other hand the nonboiled aqueous extractshowed very little hypotensive activityThe hypotensive effectof the boiling water extract appeared not to be mediated viaadrenergicmuscarinic ganglionic or serotonergic receptorshowever histamine antagonists inhibited the hypotensiveeffect in a dose-related manner [75]

417 Oculohypotensive Activity The aqueous seed extract ofF vulgare demonstrated significant oculohypotensive activityusing water loading and steroid induced glaucoma modelThis extract exhibited 1749 2116 and 2203 reduction ofintraocular pressure in normotensive rabbits at 03 06and 12 (wv) concentrations respectively A maximummean difference of 3120 was observed between vehiclestreated and extracts treated eyes in water loading experi-mental animal model while a maximum mean intraocularpressure lowering of 3129 was observed in steroid inducedmodel of glaucoma Thus the aqueous extract of F vulgarerevealed oculohypotensive activity which was found to be asgood as that of reference standard antiglaucoma drugs calledtimolol [84]

418 Antithrombotic Activity Tognolini et al [55] providedevidence of potent inhibitory activity of essential oil of F vul-gare against platelet aggregation induced byADP arachidonicacid and collagen in guinea pig plasma Similar findingswere reported by Yoshioka and Tamada [109] for aggregationof rabbit platelets by an aromatic factor of fennel oil Theessential oil and anethole (a constituent of oil) of F vulgaretested in vitro in rat aorta with or without endotheliumdisplayed comparable NO-independent vasorelaxant activityat antiplatelet concentrations It supports the safety of Fvulgare that is free from cytotoxic effects Anethole and Fvulgare did not cause cytotoxicity when incubated for 30minupto 300 120583gmL in platelet viability test This concentrationwas largely compatible with those adopted in the functionalin vitro tests In vivo both F vulgare essential oil andanethole orally administered in a subacute treatment to mice(30mgkgday for 5 days) showed significant antithrom-botic activity preventing the paralysis induced by collagen-epinephrine intravenous injection (70 and 83 protectionresp)Thus essential oil and its main component anethole ofF vulgare showed a safe antithrombotic activity in guinea pigplasma that seems due to their broad spectrum antiplateletactivity clot destabilizing effect and vasorelaxant action [55]

419 Antimutagenic Effect Essential oil of F vulgare revealednoteworthy protective effects against genotoxicity in mice

24 BioMed Research International

induced by cyclophosphamide Genotoxicity and cytotoxicitywere assessed by using mice bone marrow chromosomalaberration micronucleus and sperm abnormality assaysrespectively Oral administration of essential oil (1 and2mLkg) significantly inhibited the frequencies of aberrantmetaphases chromosomal aberrations micronuclei forma-tion and cytotoxicity in mouse bone marrow cells inducedby cyclophosphamide and also produced a significant reduc-tion of abnormal sperm and antagonized the reduction ofcyclophosphamide induced superoxide dismutase catalaseand glutathione activities and inhibited increased malondi-aldehyde content in the liver Additionally F vulgare inhibitsthe oxidative stress induced by cyclophosphamide [90]

420 Gastrointestinal Effect Theaqueous extract of F vulgareshowed remarkable antiulcerogenic effect against ethanol-induced gastric lesions in rats It was found that pretreatmentwith aqueous extract significantly reduced ethanol-inducedgastric damageThis effect of aqueous extract was highest andstatistically significant in 300mgkg group comparedwith thecontrol (119875 lt 0001) group of animal Additionally aqueousextract of F vulgare significantly reduced the whole bloodmalondialdehyde levels while significantly increased nitritenitrate ascorbic acid retinol and beta-carotene levels Thusaqueous extract of F vulgare fruit had clearly a protectiveeffect against ethanol-induced gastric mucosal lesion in rats[81]

421 Chemomodulatory Action The chemopreventive effectof different doses of test diet of Foeniculum vulgare seeds wasexamined against 712-dimethylbenz(a)anthracene- (DMBA-) induced skin papillomagenesis and benzo(a)pyrene-[B(a)P-] induced forestomach papillomagenesis at the peri-initiational level in Swiss albino mice Fennel seeds exhibita significant reduction in the skin and the fore-stomachtumor incidence and tumor multiplicity as compared tothe control group Further biochemical assays showeda significant increase in the contentactivities of phase Ienzymes especially in the case of 6 test diet A concomitantincrease in the activities of the phase II enzymes wasobserved with all the doses of test diet under study Asignificant enhancement in the activities of antioxidantenzymes was observed especially at 4 and 6 test diets offennel These findings were indicative of chemopreventivepotential of fennel against carcinogenesis This is the firstreport showing chemopreventive potential of seeds of fennelagainst carcinogenesis [85]

422 Cytoprotection and Antitumor Activity Anethole is theprincipal active component of fennel seeds which has exhib-ited anticancer activity Al-Harbi et al studied the antitumoractivity of anethole against Ehrlich ascites carcinoma inducedin a tumor model in Swiss albino mice The study revealedthat anethole increased survival time reduced tumor weightand reduced the volume and body weight of the Ehrlichascites tumour-bearing mice It also produced a significantcytotoxic effect in the Ehrlich ascites tumour cells in the pawreduced the levels of nucleic acids and malondialdehyde and

increased glutathione concentrations [110] In vitro cytopro-tection activity of methanolic extract of Foeniculum vulgarewas evaluated against normal human blood lymphocytes bymicronucleus assay and antitumor activity against B16F10melanoma cell line by Trypan blue exclusion assay for cellviability Lymphocyte culture treated with 70 methanolicextract of Foeniculum vulgare showed very less percentage ofmicronucleus that is 0006 as compared to standard drugdoxorubicin which showed 0018 micronucleus On theother hand 70methanolic extract of Foeniculum vulgare haspotent antitumor activity at the concentration of 200120583gmLThe results suggest that the Foeniculum vulgare could beconsidered as a natural resource of antitumor agents as wellas cytoprotective to normal cells [11]

423 Cytotoxicity Kaileh and his coworker investigated thecytotoxic effect of organic extracts of 24 selected Palestinianmedicinal plant species The plant selection was based onexisting ethnobotanic information and interviews with localhealers The extracts of the plants under investigation weretested for their potential antitumor (cytotoxic) effect on themurine fibrosarcoma L929sA cells and on the human breastcancer cells MDA-MB231 and MCF7 The extract from Fvulgare presented an IC (50) value at 24 h of 700 plusmn 28 and500plusmn17 120583gmL on L929sA andMCF7 cells respectivelyThenuclear transcription factor NFkappaB or NF120581B regulatesthe expression of various genes They further investigatedthe effect of nine promising plant extracts withheld fromthe first cell viability screening on NF120581B activation Thedichloromethane and methanol (1 1) extract of aerial part ofF vulgare revealed immunomodulatory NF120581B activities [82]Also Berrington and Lall investigated the in vitro cytotoxicityof acetone extracts of F vulgare and other eight medicinalplants against a noncancerous African green monkey kidney(Vero) cell line and an adenocarcinoma cervical cancer(HeLa) cell line [87]

424 Antipyretic Activity F vulgare extract showedantipyretic activity against hyperpyrexia in mice It wasinduced by SC administration of 2mL100 g of a 20aqueous suspension of brewerrsquos yeast As an antipyreticagent ethanolic extract of F vulgare fruit showed a moderateantipyretic activity that was statistically significant after 30and 90min (119875 lt 001) [108]

425 Hypolipidemic Activity The aqueous extract of F vul-gare revealed notable hypolipidemic and antiatherogenicactivity against Triton WR-1339 induced hyperlipidemiain mice Aqueous extract causes significant reduction ofplasma lipid levels that is cholesterol triglycerides LDL-cholesterol and apolipoprotein-B decreased by 40 2361 and 61 respectively and increase in HDL-cholesteroland apolipoprotein A1 by 85 and 58 respectively [88]

426 Hypoglycemic Activity The essential oil of F vulgareexhibits potential hypoglycemic and antioxidant activityagainst streptozotocin induced diabetes in rats Essentialoil (30mgkg body weight) of F vulgare works in the

BioMed Research International 25

correction of hyperglycemia from 1625 plusmn 319mgdL to8197 plusmn 197mgdL with 119875 lt 005 and the activity of serumglutathione peroxidase from 5972 plusmn 278Ug Hb to 9960 plusmn638Ug Hb with 119875 lt 005 Also essential oil of fennelimproves the pathological changes noticed in their kidneyand pancreas as compared with the control group of animalThis can prove its effect as antidiabetic in folk Medicine Thismakes the possibility of its inclusion in antidiabetic drugindustry [12]

427 Antispasmodic Activity The antispasmodic activity of25 and 100mLL of alcoholic extract of Foeniculum vulgarealong with other Germanic medicinal plants namelyMelissaofficinalis Rosmarinus officinalisMentha piperitaMatricariachamomilla Carum carvi and Citrus aurantium were testedemploying the guinea pig ileum and using acetylcholine andhistamine as spasmogens An alcoholic extract of the fruits ofFoeniculum vulgare possesses antispasmodic activity whichinhibits the acetylcholine and histamine-induced guineapig ileal contractions in vitro An essential oil which isobtained from the fruits of Foeniculum vulgare 25 120583gmL and10 120583gmL respectively inhibited oxytocin and prostaglandin[72]

428 Apoptotic Activity The apoptotic activities of ethanolextracts from fruits of seven species of Apiaceae familynamely Eryngium planum Archangelica officinalis Pasti-naca sativa Heracleum sibiricum Carum carvi Foenicu-lum vulgare and Levisticum officinale against ML-1mdashhumanacute myeloblastic leukaemia J-4501mdashhuman acute Tcell leukaemia EOLmdashhuman eosinophilic leukaemia HL-60mdashhuman Caucasian promyelocytic leukaemia 1301mdashhuman T cell leukaemia lymphoblast C-8166mdashhuman Tcell leukaemia U-266B1mdashhuman myeloma WICLmdashhumanCaucasian normal B cell and H-9mdashhuman T cell wereinvestigated with the help of Trypan blue assay and AnnexinV fluos assay [86] The ethanol extract from fruit F vulgareshowed the highest mortality in Trypan blue test for J45cell linemdash4 of viable cells and for C8166 cell linemdash100of mortality However the cells of other lines showed thehighest viability HL60mdash60 EOLmdash48 and MLmdash1ndash42The normal cell line H9 and WICL showed 35 and 25of viable cells respectively C8166 cell line and J-45 cell lineshowed the highest level of the apoptotic cells detected byAnnexin V methodmdash100 and 93 respectively Howeverthe cells of two lines HL60 and EOL-1 showed the lowerlevels of apoptotic cellsmdash52 and 60 respectively Highpercentage of apoptotic cells was observed inH9 andWICLmdash76 and 93 respectively [86]

429 Human Liver Cytochrome P450 3A4 Inhibitory ActivityThirteen compounds isolated from the methanolic extract offennel have been found to possess human liver cytochromeP450 3A4 inhibitory activity Among these compounds 5-methoxypsoralen (5-MoP) showed the strongest inhibitionwith an IC50 value of 183120583m and with a mixed type ofinhibition [83]

430 Antiaging Effects Rasul and his coworker developeda base and formulation containing 4 concentrated seedextract of F vulgare This formulation shows notable antiag-ing effect with supporting experimental data related to skinmoisture and transepidermal water loss (TEWL) The basewas insignificant while the formulation showed significanteffects on skin moisture and TEWL The texture parameterenergy showed a significant increase proving that the formu-lation possesses potential antiaging effects [50]

431 Bronchodilatory Effect Ethanol extract and essential oilfrom F vulgare exhibited bronchodilatory activity on con-tracted tracheal chains of guinea pig The potassium channelopening effect of fennel may contribute on its relaxant effecton guinea pig tracheal chains [111] Moreover anethole bearsa striking resemblance to the catecholamines epinephrinenorepinephrine and dopamine This structural similarityappears to be responsible for the various sympathomimeticactivities of F vulgare such as bronchodilatory effect [71]

432 Antioxidant Activities Naturally occurring antioxi-dants can be used to protect human beings from oxidativestress damage [112] Fennel was known as excellent source ofnatural antioxidants and contributed to the daily antioxidantdiet [113]Wild fennel was found to exhibit a free radical scav-enging activity with higher content phenolic and flavonoidthan medicinal and edible fennel and the aerial parts ofthe Italian fennel populations showed the highest DPPHscavenging activity [65] Phenolic compounds of fennelincluding caffeoylquinic acid rosmarinic acid eriodictyol-7-orutinoside quercetin-3-O-galactoside and kaempferol-3-O-glucoside showed antioxidant activities [67] The volatileoil showed strong antioxidant activity in comparison withbutyrated hydroxyanisole and butylated hydroxytolueneEthanol and water extracts of fennel showed less antioxidantactivity compared with essential oil [114]

5 Environmental Application

Foeniculum vulgare that is fennel not only exhibited phar-macological activities but also revealed a few environmentalactivities These activities play a key role in the managementof nematode insect mosquitoes and some harmful larvae ofmalaria producing vector Thus the extracts of F vulgare andisolated biologically active compounds have been evaluatedfor their insecticidal repellent acaricidal larvicidal andnematicidal activity [115ndash119] A brief review on the differenttype of ecofriendly environmental activities as reported onthis plant is summarized below

51 Insecticidal Activities The fruit derived phytoconstitu-ents of F vulgare exhibited prominent insecticidal activi-ties against Sitophilus oryzae Callosobruchus chinensis andLasioderma serricorne This activity was examined usingdirect contact application and fumigation methods Thebiologically active constituents that is phenylpropenes (E)-anethole and estragole and the monoterpene (+)-fenchonewere characterized from Foeniculum fruit By using a filter

26 BioMed Research International

paper diffusion test estragole (0168mg cmminus2) caused 91mortality to S oryzae within 1 day after treatment whereas(+)-fenchone and (E)-anethole gave over 90 mortality at 2and 4 day after treatment respectively

After 2 days of treatment all test compounds (0021mg cmminus2 concentration) revealed potent insecticidal activityagainst C chinensis Whereas after 1 day of treatment (E)-anethole (0105mg cmminus2) gave 100mortality of L serricornewhereas 90 and 60 mortality at 4 day after treatment wasachieved with estragole and (+)-fenchone respectively In afumigation test the compounds were much more effectiveagainst adults of S oryzae C chinensis and L serricorne inclosed cups than in open ones indicating that the insecticidalactivity of test compounds was largely attributable to fumi-gant action As naturally occurring insect-control agents theF vulgare fruit-derived materials described could be usefulfor managing field populations of S oryzae C chinensis andL serricorne [116]

52 Acaricidal Activity Fennel oil shows significant acaricid-al activity againstDermatophagoides farinae andDermatoph-agoides pteronyssinus (+)-fenchone and p-anisaldehyde aremajor constituents of fruit oil of F vulgare P-anisaldehydewas the most toxic compound against D farinae and is muchmore effective compared with benzyl benzoate thymol andestragol [118]

53 Repellent Activity The methanolic extract of fruits ofF vulgare was spectroscopically characterized for the pres-ence of biologically active constituents called (+)-fenchoneand (E)-9-octadecenoic acid The repellent activity of theseconstituents was tested against hungry Aedes aegypti femaleswith the help of skin and patch tests and compared withthat of the commercial repellent agent called NN-diethyl-m-toluamide (DEET) and (Z)-9-octadecenoic acid In askin test with female mosquitoes (+)-fenchone and (Z)-9-octadecenoic acid (04mgcm2) exhibitedmoderate repellentactivity at 30min after treatment whereas DEET providedgt1 h of protection against adult mosquitoes at (02mgcm2)Thus (+)-Fenchone and (E)-9-octadecenoic acid are poten-tial mosquito repellent agents or lead compounds [117]

54 Larvicidal Activity Plant extracts and oils may act asalternatives to conventional pesticides for malaria vectorcontrol By considering this aspect Sedaghat et al [119] inves-tigated the larvicidal activity of essential oils of three plantsof Apiaceae family against malaria vector called Anophe-les stephensi The larvicidal activity was evaluated againstlaboratory-reared larvae by standard method of WHO TheF vulgare oil was the most effective against A stephensiwith LC(50) and LC(90) values of 2010 and 4451 ppmrespectively [119] Additionally the essential oil extracts fromleaves flowers and roots of F vulgare exhibit noticeablelarvicidal activity against fourth-instar larvae of themosquitoCulex pipiens molestus Terpineol and 18-cineole content of Fvulgare are the most effective phytoconstituent against Culexpipiens molestus bites offering complete protection for 16 and2 h respectively [120] Recently Zoubiri et al [57] reported

the larvicidal activity of essential oil of fennel seed againstCulex pipiensmosquitoThus F vulgare can serve as a naturallarvicidal agent

55 Nematicidal Activity Oka et al investigated the in vitronematicidal activity of essential oils extracted from 27 spicesand aromatic plants in pot experiments Twelve of thetwenty-seven essential oils immobilized more than 80 ofjuveniles of the root-knot nematodeMeloidogyne javanica ata concentration of 1000 120583Lliter At this concentration mostof these oils also inhibited nematode hatching Essential oilsof Carum carvi Foeniculum vulgare Mentha rotundifoliaand Mentha spicata showed the highest nematicidal activityamong the in vitro tested oils In 3-liter pot experimentsnematicidal activity of the essential oils and their componentswas confirmed at 200 and 150mgkg respectivelyThe resultssuggest that the essential oils and theirmain componentsmayserve as nematicides [115]

6 Toxicity

The long history of ethnomedicinal application with noreports of any serious side effects suggests that F vulgarecould be considered as safe Inmost toxicity experiments car-ried out on F vulgare no sign of toxicity was observed Shahand his coworker in 1991 investigated the detailed toxicityaccount of ethanolic extract of fennel fruit in experimentalmice with respect to acute and 90 days longer term toxicity[121] In experimentation Shah and his coworker observedthe general symptoms of toxicity and mortality for only 24 hin acute toxicity Whereas in another part of toxicity theystudied the effect of fennel extract on mice with 90 dayslong term treatment Acute toxicity of ethanolic extract of Fvulgarewas assessed in 35mice by using three concentrationsnamely 05 1 and 3 gkg body weight In this investigation Fvulgare exhibited no signs of toxicity and no mortality wasobserved upto the dose level 3 gkg body weight In case oflonger term toxicity ethanolic extract of F vulgare (100mgkgbody weightday) was given in drinking water of animals(30 male and 30 female mice) All external morphologicalhaematological and spermatogenic changes in addition tobody and vital organ weights were recorded The extractcaused no significant chronic mortality as compared tocontrols during this investigation The treated male micegained significant weight during chronic treatment while aloss or no significant change in weight was noticed in thefemale mice treated with the same extract The extracts didnot show spermatotoxic effects Thus Shah and his coworkerconcluded that fennel extract is safe based on both acuteandor long term toxicity studies [121] Additionally the plantextract in doses of 05 1 and 3 gkg (orally) did not causeany deaths These doses do not show any type of toxicityagainst several parameters tested namely locomotor activitybizarre reactions sensitivity to sound social interaction tailposture aggressive behaviour ataxia paralysis convulsionstremors prostration exophthalmos pupil size defecationsalivation urination pattern of respiration nasal dischargecyanosis and piloerection Exceptionally only the 3 gkg dose

BioMed Research International 27

showed signs of reduced locomotor activity and piloerec-tion Otherwise all other parameters were negative [108]In another experiment of acute toxicity different solventextracts namely n-hexane methylene chloride ethyl acetateand methanol extracts of F vulgare upto 55 gkg concentra-tion did not revealed any kind of toxicity in mice LD50being 675 110 692 and 15 gkg for n-hexane methylenechloride ethyl acetate and methanol extracts respectively[68] The plant extract of F vulgare was administered orallyat a dose of 100 200 400 600 800 1000 and 2000mgkgof body weight of mice Each group of animals was undervisual observation for 10 days for the external behavior ofneurological toxicity created by plant extract Even the micereceiving highest dose of F vulgare extract did not show anymortality or toxicity demonstrating the safety profile of theplant extract [89]

The acute oral 50 LD50 for anethole in rats was foundto be 2090mgkg Repeated doses of one-third the LD50 ofanethole (695mgkg) given to rat caused mild liver lesionsIt would therefore appear that in normal therapeutic dosagesanethole would have minimal hepatotoxicity When anetholewas fed to rats daily for one year as 025 of the dietno hepatic damage was seen [122] The acute oral LD50 ofessential oil in rats is 1326mgkg [76] The use of F vulgareessential oil as a remedy for control of primary dysmenorrheaincreases concern about its potential teratogenicity due toits estrogen like activity Evaluation of teratogenicity ofessential oil using limb bud mesenchymal cells showed thatthe essential oil may have toxic effect on fetal cells butthere was no evidence of teratogenicity upto concentrationof 93mgmL of culture medium [123] The overall toxicitystudies carried out on F vulgare accounts for its safety at therecommended therapeutic doses

7 Conclusions

The available scientific research on Foeniculum vulgarehas shown that it is an important medicinal plant used ina wide range of ethnomedical treatments especially forabdominal pains antiemetic aperitif arthritis cancer colicin children conjunctivitis constipation depurative diarrheadieresis emmenagogue fever flatulence gastralgia gastritisinsomnia irritable colon kidney ailments as a laxativeleucorrhoea liver pain mouth ulcer and stomachache Thisplant has been in use for a long period of time withoutany documented serious adverse effects Studies carriedout in the past and present indicate that fennel possessesdiverse health benefits and are an important constituentof food Studies have shown that various extracts offennel possess a range of pharmacological actions such asantiaging antiallergic anticolitic antihirsutism anti-inflam-matory antimicrobial and antiviral antimutagenic antino-ciceptive antipyretic antispasmodic antistress antithromb-otic anxiolytic apoptotic cardiovascular chemomodulatoryaction cytoprotection and antitumor cytotoxicity diureticestrogenic properties expectorant galactogenic gastrointes-tinal effect hepatoprotective human liver cytochrome P4503A4 inhibitory hypoglycemic hypolipidemic memory-en-hancing property nootropic and oculohypotensive activity

supporting its traditional use However the most prominentand the well studied effects are the antimicrobial andantioxidant effects of essential oil of fennel in differentexperimental models The observed health benefits may becredited to the presence of the various phytochemicals likevolatile compounds flavonoids phenolic compounds fattyacids and amino acids

Fennel also contains mineral and trace elements likealuminum barium calcium cadmium cobalt chromiumcopper ironmagnesiummanganese nickel lead strontiumand zinc [124] fat soluble vitamins such as vitamins A Eand K water soluble vitamins like ascorbic acid thiamineriboflavin niacin and pyridoxine essential amino acidslike leucine isoleucine phenylalanine and tryptophane maycontribute to the myriad health beneficial effects at least inpart

Most of the pharmacological studies were conductedusing uncharacterized crude extracts of fennel It is difficultto reproduce the results of these studies and pinpoint thebioactive compounds Hence there is a need for chemi-cal standardization and bioactivity-guided identification ofbioactive compounds Among several classes of chemicalconstituents identified in fennel volatile components of fen-nel essential oil and phenolic compounds are assumed to bethe main bioactive compounds responsible for the majorityof its pharmacological effects However the vast traditionaluse and proven pharmacological activities of fennel indicatethat an immense scope still exists for its chemical explorationFuture studies should be focused on validating the mecha-nism of action responsible for the various beneficial effectsand also on understanding which plant based compounds areresponsible for the reported effectsThe required informationwhen available will enhance our knowledge and appreciationfor the use of fennel in our daily diet Also the outcomeof such chemical studies may further expand its existingtherapeutic potential

Thus there are many areas of research related to thisplant that need to be further explored to fully recognize itsbeneficial effects for society Factors such as geographical andseasonal variation play an important role in the authentica-tion of the chemical constituents responsible for the activitywhich also can be an area of interest Thus it is incumbenton researchers to fill the huge gap of insufficient knowledgeand create awareness among pharmacologists as well as inves-tigators towards providing better medicinal value derivedfrom this plant This can be fulfilled only by generatinginterest among the research community through writing ofcritical appraisals (paper) and extending the interdisciplinaryresearch area to focused studies on Foeniculum vulgare

They are greenish-yellow the colour of hay from which theterm fennel is derived Wild fruits are short dark colouredand blunt at their ends and have a less agreeable flavourand odour than those of sweet fennel Seeds ripen fromSeptember to October This plant can reproduce from crownor root fragments but freely reproduces from seed

13 Chemical Composition and Nutritional Value of FennelFoeniculum vulgare is widely grown for its edible fruit orseeds These are sweet and dry a fully ripe specimen isan exquisite fruit The fruit is often dried for later use andthis dried fruit called fennel is a major item of commerceTable 2 lists the nutrient composition of fennel (USDA data)Fennels are one of the highest plant sources of potassiumsodium phosphorus and calcium According to USDA datafor the Mission variety fennels are richest in dietary fiberand vitamins relative to human needs They have smalleramounts of many other nutrients

Table 3 summarizes the chemical composition andthe nutritional value [14] of different parts of fennelnamely shoots leaves stems and inflorescence Leavesand stems show the highest moisture content (7636 and7746 g100 g resp) while inflorescence exhibits the lowestcontent (7131 g100 g) Carbohydrates are the most abundantmacronutrients in all the parts and range from 1844 to2282 g100 g Proteins reducing sugars and fats are theless abundant macronutrients proteins varied between108 g100 g in stems and 137 g100 g in inflorescences Theinflorescences and stems revealed the highest fat content(128 g100 g) and reducing sugar content (149 g100 g)respectively amongst all the parts of fennel On the basisof the proximate analysis it can be calculated that a freshportion of 100 g of these parts yields on average 94Kcal of

energy The highest values were obtained for inflorescenceswhile leaves and stems gave the lowest energy contribution

About twenty-one fatty acids were identified and quanti-fied from the abovementioned parts of fennel (Table 3)Theseare caproic acid caprylic acid capric acid undecanoic acidlauric acid myristic acid myristoleic acid pentadecanoicacid palmitic acid heptadecanoic acid stearic acid oleicacid linoleic acid 120572-linolenic acid arachidic acid eicosanoicacid cis-1114-eicosadienoic acid cis-111417-eicosatrienoicacid + heneicosanoic acid behenic acid tricosanoic acidand lignoceric acid Thus Barros and his coworker concludepolyunsaturated fatty acids (PUFA) to be the main groupof fatty acids present in all the fennel parts On the otherhand Vardavas and his coworker reported monounsaturatedfatty acids (MUFA) as the main group of fatty acids infennel [22] Nevertheless unsaturated fatty acids (UFA) rangefrom 66 to 80 and predominate over saturated fatty acids[14] The highest concentration of n-3 fatty acids was foundin fennel leaves while the lowest concentration was found

in inflorescences The ratio of 1205966 to 1205963 fatty acids has animportant role in the human diet The highest levels of n-3fatty acids found in leaves contributed to its lowest ratio of1205966 to 1205963 fatty acids The lowest levels of n-3 fatty acids foundin inflorescences contributed to its highest ratio of 1205966 to 1205963fatty acids

Fennels have smaller amounts of many other nutrientsOn a weight basis fennels contain more calcium (49mg100 g) as compared with apples (714mg100 g) bananas(388mg100 g) dates (250mg100 g) grapes (1086mg100 g) orange (4025mg100 g) prunes (180mg100 g) rais-ins (400mg100 g) and strawberries (1401mg100 g) Phe-nolics are an important constituent of fruit quality becauseof their contribution to the taste colour and nutritionalproperties of fruit Amongst the phenolics analyzed in thefruit of this plant are neochlorogenic acid (140) chloro-genic acid (298) gallic acid (0169) chlorogenic acid(6873) caffeic acid (2960) p-coumaric acid (4325)ferulic acid-7-o-glucoside (5223) quercetin-7-o-glucoside

32 Flavonoids Flavonoids are generally considered as animportant category of antioxidants in the human dietFlavonoids are abundant in the plants of Apiaceae family Ithas been reported that the presence of flavonol glycosidesin fennel species is related to its morphological hetero-geneity and variation Total flavonoid content of hydroal-coholic extracts is about 123 plusmn 018mgg Flavonoids likeeriodictyol-7-rutinoside quercetin-3-rutinoside and ros-marinic acid have been isolated from F vulgare [65]Amongst the flavonoids present in F vulgare the most preva-lent are quercetin-3-glucuronide isoquercitrin quercetin-3-arabinoside kaempferol-3-glucuronide and kaempferol-3-arabinoside and isorhamnetin glucoside [66] Quercetin-3-O-galactoside kaempferol-3-O-rutinoside and kaempferol-3-O-glucoside have also been reported to occur in the aque-ous extract of F vulgare [67] The flavonoids like isorham-netin 3-O-120572-rhamnoside quercetin and kaempferol werealso isolated from the ethyl acetate extract whereas quercetin3-O-rutinoside kaempferol 3-O-rutinoside and quercetin3-O-120573-glucoside were isolated from the methanol extractThese flavonoids exhibit remarkable antinociceptive and anti-inflammatory activity [68] Further quercetin rutin andisoquercitrin were reported to have the immunomodulatoryactivities [69]

33 Phenolic Compounds There has been a growing interestin phenolic components of fruits and vegetables which maypromote human health or lower the risk of disease Aqueous

extract of fennel fruits are rich in phenolic compoundsMany of them have antioxidant activities and hepatopro-tective properties The phenolic compounds present in Fvulgare are considered to be associated with the preventionof diseases possibly induced by oxidative stress such ascardiovascular diseases cancer and inflammation Thesephenolic compounds have received tremendous attentionamong nutritionists food scientists and consumers dueto their role in human health Fennel has been reportedto contain hydroxyl cinnamic acid derivatives flavonoidglycosides and flavonoid aglycones [67] The methanolicextract of fennel seeds contains rosmarinic acid chlorogenicacids as major phenolic compounds (149 and 68 resp)and quercetin and apigenin as themajor flavonoids (171 and125 resp) Also the total phenolic compounds in fennelmethanol extract were higher than the flavonoid compounds[23] F vulgare has been reported to contain phenolic acidslike 3-O-caffeoylquinic acid 4-O-caffeoylquinic acid 5-O-caffeoylquinic acid 13-O-di-caffeoylquinic acid 14-O-di-caffeoylquinic acid and 15-O-di-caffeoylquinic acid [65]Two compounds A and B were isolated and character-ized for the first time from the wild fennel and identi-fied as 34-dihydroxyphenethylalchohol-6-O-caffeoyl-120573-D-glucopyranoside and 3101584081015840-binaringenin respectively Thetotal phenolic and flavonoid contents ofwild fennel (24 and12 resp) were less as compared to cultivated fennel (31and 16 resp) [70]

4 Pharmacological Activities

Foeniculum vulgare is officially noted in Ayurvedic Pharma-copoeia as an important part of polyherbal formulations inthe treatment of different diseases and disorders A numberof biological-pharmacological studies have been undertakento evaluate the indigenous uses of F vulgare Few extracts of Fvulgare and isolated compounds have been evaluated for sev-eral activities namely antiaging antiallergic anticolitic anti-hirsutism anti-inflammatory antimicrobial and antiviralantimutagenic antinociceptive antipyretic antispasmodic

Bacillus subtilis Escherichia coliKlebsiella pneumoniaMicro-coccus luteus Pseudomonas putida Pseudomonas syringaeand Candida albicans According to the results reported byGulfraz et al [92] essential oil of F vulage had significantantimicrobial activities against some of microorganisms ascompared to the methanolic and ethanolic extracts Thediameters of growth inhibition zone ranged from 14 to 31mm(including the diameter of the disc 6mm) with the highestinhibition zone values observed against Bacillus megaterium(31mm) and Bacillus subtilis (29mm) Roby et al [23]investigated antimicrobial effect of the methanol ethanoldiethyl ether and hexane extracts of seed of F vulgare againsttwo species of Gram negative bacteria (Escherichia coli andSalmonella typhi) two species of Gram positive bacteria(Bacillus cereus and Staphylococcus aureus) one species ofyeast (Candida albicans) and one species ofmold (Aspergillusflavus)Themethanolic extract showedmore effective antimi-crobial activity than the other extracts The results fromthe disc diffusion method followed by measurement ofminimum inhibitory concentration (MIC) indicated thatBacillus cereus and Aspergillus flavus were the most sensitivemicroorganisms tested showing the largest inhibition zonesand the lowest MIC values Least activity was exhibitedagainstEscherichia coli with the smallest inhibition zones andthe highest MIC value [23] Shrivastava and Bhargava [93]investigated the antibacterial effect of the crude chloroformand methanol extract of leaves and flowers of F vulgarealong with Raphanus sativus and Brassica nigrum againstEscherichia coli and Staphylococcus aureus Methanol extractof flower of F vulgare showed significant activity againstEscherichia coli whereas crude and chloroform extractsfailed to exhibit antimicrobial activity against Staphylococcusaureus (Table 9) Among different tested bacterial strains the

methanolic fruit extract of F vulgare inhibited the growthof Staphylococcus aureus and Bacillus pumilus with 1127 and1267mm zone of inhibition respectively [7]

Several studies indicating the antifungal effect of Fvulgare along with antibacterial effect are also reported inthe literature Martins et al [94] investigated the antibacterialand antifungal effects of three essential oils of Portugueseplants namely Foeniculum vulgareMentha spicata and Ros-marinus officinalis against Staphylococcus aureus Escherichiacoli Klebsiella pneumonia Pseudomona aeruginosa Staphy-lococcus epidermidis Candida albicans and phytopathogenic

diseases [97] In an in vitro study aqueous and alcoholicseed extracts of F vulgare exhibited inhibitory effect againstAlternaria alternata Mucor rouxii and Aspergillus flavus[98] Interestingly aqueous seed extract of F vulgare showedstrongest antifungal activity as compared to reference fungi-cidal agent that is griseofulvin [99]

All of the above mentioned studies were carried outon the crude extracts and it is difficult to pinpoint theactive antimicrobial metabolite A phenylpropanoid deriva-tive called dillapional characterized from F vulgare stem wasfound to be an antimicrobial constituent with MIC values of125 250 and 125 against Bacillus subtilis Aspergillus nigerand Cladosporium cladosporioides respectively A coumarinderivative scopoletin was also isolated as a marginallyantimicrobial agent [100] The characterization of sevendifferent types of oxygenatedmonoterpenes frommethylene

chloride crude extract of F vulgare [101] suggested thatthe crude extract containing monoterpenes could be a newmedicinal resource for antibacterial agents

A total of 78 compounds were identified from theactive antimycobacterial fraction of F vulgare with thehelp of gas chromatography-mass spectra (GC-MS) Outof these twenty compounds were tested against one sensi-tive and three MDR strains of Mycobacterium tuberculosisusing the Alamar Blue microassay Compounds that showedsome degree of antimycobacterial activity against all strainstested were the following linoleic acid (MIC 100 120583gmL)oleic acid (MIC 100 120583gmL) 13-benzenediol (MIC 100ndash200120583gmL) undecanal (MIC 50ndash200120583gmL) and 24-undecadienal (MIC 25ndash50120583gmL) 24-Undecadienal wasthe most active compound against multidrug resistant Mtuberculosis speciesThus the dietary intake of F vulgaremaylower the risk ofM tuberculosis infection [63]

Orhan et al [5] studied the antiviral activity of theessential oil of fruit sample of F vulgare along with 12other Turkish medicinal plants against the DNA virusHerpessimplex type-1 (HSV-1) and the RNA virus parainfluenzatype-3 (PI-3) Most of the oils and compounds displayedstrong antiviral effects against HSV-1 ranging between 08and 0025 120583gmL However the samples tested were lesseffective against PI-3 with results ranging between 16 and02 120583gmL Only the essential oils of Anethum graveolensFoeniculum vulgare (fully mature) Mentha piperita Menthaspicata Ocimum minutiflorum Ocimum vulgaris and Sat-ureja cuneifolia inhibited this virus significantly

All these literature findings validated the traditional usesof Foeniculum vulgare in infectious disorders like abdomi-nal pains antiemetic arthritis conjunctivitis constipationdepurative diarrhea dieresis fever flatulence gastralgia gas-tritis insomnia irritable colon mouth ulcer stomachacherespiratory disorders skin diseases and so forth There isalways a need for new antimicrobial agents due to rapiddevelopment of resistance Bioactive metabolites of F vulgaremay be a potential source for new antimicrobial agents

42 Anti-Inflammatory Activity Oral administration ofmethanol extract of F vulgare fruit to rat and mice exhibitedinhibitory effects against acute and subacute inflammatorydiseases The anti-inflammatory activity of methanol extractwas evaluated by using three screening protocols namelycarrageenan-induced paw edema arachidonic acid-inducedear edema and formaldehyde-induced arthritis Theseare widely used for testing nonsteroidal anti-inflammatorydrugs For acute inflammationmethanol extract (200mgkg)exhibits significant inhibition of paw edema (69) inducedby carrageenan injection as compared to the control groupof animals Methanol extract of F vulgare also inhibitsear-edema (70) induced by arachidonic acid in mice Thelevel of serum transaminase aspartate aminotransferase(AST) and alanine aminotransferase (ALT) significantlyincreases in the presence of methanolic extract of F vulgareon inflammation induced by formaldehyde as comparedto control group The assessment of the level of AST and

ALT provides a good and simple tool to measure the anti-inflammatory activity of the target compounds [102] Theseoverall results seem to suggest that F vulgare FME mayact on both the cyclooxygenase and lipoxygenase pathways[79]

43 Antiallergic Activity Methanolic extract of F vulgarefruit showed significant inhibitory effect on DNFB- (24-dinitrofluorobenzene-) induced delayed type hypersensitiv-ity after oral administration of 200mgkg once a day for7 days The inhibitory effect on immunologically inducedswelling suggests the possible immunosuppressive propertiesof F vulgare [79]

44 Hepatoprotective Activity Essential oil of F vulgareseeds revealed a potent hepatoprotective effect against acutehepatotoxicity produced by carbon tetrachloride in ratsOral administration of F vulgare essential oil decreases thelevels of serum aspartate aminotransferase (AST) alanineaminotransferase (ALT) alkaline phosphatase (ALP) andbilirubin as compared to the control group Ozbek et alsuggest that the constituents (d-limonene and 120573-myrcene) ofessential oil may have played a key role in the protection ofliver from CCl

4toxicity [9]

45 Anxiolytic Activity Anxiety is the unpleasant feeling offear and concern When anxiety becomes excessive it maybe considered as an anxiety disorder Anxiolytic fennel isa drug used for the treatment of anxiety and its relatedpsychological and physical symptoms Naga Kishore et al[89] investigated the anxiolytic activity of ethanolic extract ofF vulgare fruit with the help of elevated plus maze rota rodopen field test and whole board models The 100 to 200mgdose of extract per kg of body weight of animal revealedsignificant activity when compared to reference anxiolyticdrug called diazepam (1mgkg) Thus fennel extract maypossess anxiolytic activity supporting its traditional claimabout anxiolytic activity reported in 19th edition of Pharma-cology and Pharmacotherapeutics by Sathodkar Bhandarkarand Rege

46 Antistress Activity Drug and food of natural originplay a significant role in public healthcare systems and arebeing investigated as remedies for a number of stress-relateddisorders [103]Thewhole plant extract of F vulgare exhibitednotable antistress effect against stress induced by forcefulswimming of test animals The key parameters that isurinary levels of vanillyl mandelic acid (VMA) and ascorbicacid in rats were used to evaluate antistress activity Theplant extract (50 100 and 200mgkg body weight) showeda significant improvement in urinary levels of VMA (119875 lt0001) and ascorbic acid excretion levels (119875 lt 0001) in testanimals when compared to the normal basal levels in controlgroup of animalsThus the extract of entire plant of F vulgareacts as an antistress agent [13]

47 Memory-Enhancing Property There are a number ofplants whose consumption is believed to enhance memory

22 BioMed Research International

and intelligence These were usually given to children as partof their food F vulgaris an ayurvedic rasayana (mixture)possessing multiple neuropharmacological activities Theantidepressant activity of fennel has been well documentedin ethnomedicine The whole plants extract (50 100 and200mgkg) of F vulgare exhibited memory-enhancing effectagainst scopolamine-induced amnesic rats This experimentwas evaluated by conditioned avoidance response (CAR)technique The CAR of rats administered with the extractincreased gradually to 95 over 7 to 12 days The acquisition(time to achieve 95 CAR) for rats administered with theextract was dose- and time-dependent compared to controlgroup which took 12 days for acquisition The percentavoidance was always higher in the extract-treated groupsas compared to control group Animals receiving 200mgkgbody weight of the extract took ten days while groups treatedwith 100 and 50mgkg doses of the extract required elevenand twelve days respectively to reach the point of acquisitionAdministration of scopolamine produced amnesia as seenfrom reduction in the observed CAR Amnesia was greaterin the control group than in extract-treated groups How-ever continued treatment with F vulgare produced betterretention and recovery in a dose-dependent manner thanthe vehicle-treated animals Recovery from scopolamine-induced amnesia in the extract-treated groups took 3ndash5 dayswhen compared to normal (control) group which took over6 days This overall progress suggests that F vulgare extractpossesses memory-enhancing property [13]

48 Nootropic Activity Alzheimerrsquos disease is a neurode-generative disorder associated with a decline in cognitiveabilities Dementia is one of the age-related mental problemsand a characteristic symptom of Alzheimerrsquos disease Thereis some evidence in favor of use of F vulgare for the treat-ment of cognitive disorders like dementia and Alzheimerrsquosdisease Methanol extract of the whole plant of F vul-gare administered for eight successive days ameliorated theamnesic effect of scopolamine and aging-induced memorydeficits inmiceThis extract increased step-down latency andacetylcholinesterase inhibition in mice significantly Thus Fvulgaremay be employed in treatment of cognitive disorderssuch as dementia and Alzheimerrsquos disease as a nootropic andanticholinesterase agent [80]

49 Antihirsutism Activity Idiopathic hirsutism is definedas the occurrence of excessive male pattern hair growth inwomen who have a normal ovulatory menstrual cycle andnormal levels of serum androgens It may be a disorder ofperipheral androgen metabolism Traditionally Foeniculumvulgare has been used as an estrogenic agent It has beenreputed to increase milk secretion promote menstruationfacilitate birth and increase libido On considering aboveaspect Javidnia and his research team evaluated the antihir-sutism activity of ethanolic extract of F vulgare seed againstidiopathic hirsutism by preparing cream containing 1 and 2of fennel extract The efficacy of treatment with the creamcontaining 2 fennel is better than the cream containing 1fennel and these two were more potent than placebo (control

group) The mean values of hair diameter reduction were78 183 and minus05 for patients receiving the creamscontaining 1 2 and 0 (placebo) respectively [78]

410 Estrogenic Properties Since the discovery of the estrusinducing effects of some plant products in 1926 consider-able effort has been devoted towards the characterizationof phytoestrogens including flavonoids isoflavonoids chal-cones coumestans stilbenes lignans saponins and essentialoils [16] F vulgare has estrogen-like activity In male ratstotal concentration of protein was found to be significantlydecreased in testes and in vasa deferentia whereas increasedin seminal vesicles and in prostate gland On the otherhand simultaneous decrease in the activities of acid andalkaline phosphatase in all these regions (except that alka-line phosphatase was unchanged in vasa) due to the oraladministration of acetone extract of F vulgare fruit wasobserved In female rats oral administration of the extract for10 days led to vaginal cornification and oestrus cycle [8] Totalconcentration of nucleic acids and protein as well as the organweights increased in both the tissues namely mammaryglands and oviducts due to the oral administration of acetoneextract (50 150 and 250120583g100 g body wt) of F vulgare seeds[104] Fennel oil was reported to exhibit estrogenic activitypromote menstruation and alleviate the symptoms of femaleclimacteric and increase libido [71] Administration of fenneloil (25 and 50 120583gmL final concentration in the organ bath)failed to exhibit any remarkable effect in uterine contrac-tion While 10 20 and 40 120583gml concentration of fennel oilrevealed significant inhibitory effect against prostaglandinE2 Fennel oil significantly reduces the frequency of uterinecontraction induced by prostaglandin E2 Thus the extractsof F vulgare have strong estrogenic activity [76]

411 Galactogenic Activity Foeniculum vulgare has been usedformillennia to increasemilk secretion [105]Thus F vulgarebelongs to galactagogue substance Structural similarity ofits main constituent anethole to dopamine seems to beresponsible for galactogenic activityDopamine acts to inhibitthe secretion of the milk-producing hormone prolactinAnethole might influence milk secretion by competing withdopamine at the appropriate receptor sites thereby inhibitingthe antisecretory action of dopamine on prolactin [71] It wasreported that anol (demethylated anethole) causes growthof the lobule-alveolar system in the mammary glands ofimmature female rabbits and induces menstruation in miceand other experimental animals Anol also gave positiveresults in the Jadassohn nipple test a test which involvesthe measurement of changes induced in the nipples ofguinea pigs subjected to the cutaneous application of sexhormones However further research suggests that the actualpharmacologically active agents responsible for galactogenicactivity are polymers of anethole such as dianethole andphotoanethole rather than anol or anethole itself [20 76]

412 Expectorant Activity F vulgare seeds stimulate theciliary motility of the respiratory apparatus and enhance the

BioMed Research International 23

external transport of extraneous corpuscles This action sug-gests a use for fennel in treating bronchial and bronchopul-monary afflictions and in particularly polluted environments[106] The volatile oil of F vulgare stimulates the contractionof the smooth muscles of the trachea an action that couldfacilitate the expectoration of mucus bacteria and othercorpuscles extraneous to the respiratory tracts [74]

413 Anticolitic Activity Essential oil of fennel regulates themotility of smooth muscles of the intestine while at thesame time reducing intestinal gas Alone or combined withother plant medicinals Foeniculum vulgare is indicated in thetreatment of spastic gastrointestinal disturbances in someforms of chronic colitis (which resist other treatments) indyspepsias from gastrointestinal atony in dyspepsias withthe sensation of heaviness in the stomach and so forthTheaddition of fennel to preparations containing anthraquinoniccomponents reduces the occurrence of abdominal pain oftenassociated with this type of laxative [73]

414 Antinociceptive Activity Antinociceptive means anysubstance that inhibits nociception which is a physiologicalprocess underlying the sensation of pain Briefly it reducesthe sensitivity to painful stimuli The various extracts ofaerial part of F vulgare namely hexane methylene chlorideethyl acetate and methanolic extract showed remarkableantinociceptive activity against acetic acid induced writhingin mice [68] The methanolic extract of the aerial parts ofF vulgare exhibited the highest antinociceptive activity at adose level of 2000mgkg while the activity exhibited by theethyl acetate extract was at dose level 800mgkgOn the otherhand n-hexane extract (700mgkg) and methylene chlorideextract (500mgkg) exhibited similar antinociceptive activi-ties being less than peripheral antinociceptive reference drug(acetyl salicylic acid) [68]

415 Diuretic Activity A diuretic is any substance thatpromotes the production of urine Briefly it is an agentthat promotes diuresis Diuretics work by promoting theexpulsion of urine (measured as the urine volume [UV]excreted) and urinary sodium (UNa) from the body and thishelps reduce the volume of blood circulating through thecardiovascular system Caceres et al [107] performed a studyin conscious animals and administered a powdered extractof the whole plant (F vulgare) which had no effect on UVor UNa The ethanolic extract of F vulgare fruit revealedexcellent diuretic activity and proves the earlier folk claimof F vulgare which was reported in the United State ofAmerica (Table 5) The fruit extract showed statistically ahighly significant diuretic effect F vulgare induced diuresis(500mgkg dose)was comparable to that of reference diureticagent urea (960mgkg dose) in mice with a urine outputthat was almost double that of the control group Thediuresis was not associated with changes in sodium andorpotassium excretion [108] In another part of the study theauthors showed that Foeniculum vulgare had little effect onthe noradrenalin contractile responses of aortic rings thus

suggesting that it worked mainly as a diuretic and natriureticwith little effect on arterial vascular tone [77]

416 Cardiovascular Activity An aqueous extract of F vul-gare leaves possesses potential cardiovascular action Thiseffect was investigated using pentobarbital-anaesthetisedmale albino Sprague-Dawley rats [75] An intravenousadministration of the lyophilized boiled water extract ofleaves produced a significant dose-related reduction in arte-rial blood pressure without affecting the heart rate or respi-ratory rate On the other hand the nonboiled aqueous extractshowed very little hypotensive activityThe hypotensive effectof the boiling water extract appeared not to be mediated viaadrenergicmuscarinic ganglionic or serotonergic receptorshowever histamine antagonists inhibited the hypotensiveeffect in a dose-related manner [75]

417 Oculohypotensive Activity The aqueous seed extract ofF vulgare demonstrated significant oculohypotensive activityusing water loading and steroid induced glaucoma modelThis extract exhibited 1749 2116 and 2203 reduction ofintraocular pressure in normotensive rabbits at 03 06and 12 (wv) concentrations respectively A maximummean difference of 3120 was observed between vehiclestreated and extracts treated eyes in water loading experi-mental animal model while a maximum mean intraocularpressure lowering of 3129 was observed in steroid inducedmodel of glaucoma Thus the aqueous extract of F vulgarerevealed oculohypotensive activity which was found to be asgood as that of reference standard antiglaucoma drugs calledtimolol [84]

418 Antithrombotic Activity Tognolini et al [55] providedevidence of potent inhibitory activity of essential oil of F vul-gare against platelet aggregation induced byADP arachidonicacid and collagen in guinea pig plasma Similar findingswere reported by Yoshioka and Tamada [109] for aggregationof rabbit platelets by an aromatic factor of fennel oil Theessential oil and anethole (a constituent of oil) of F vulgaretested in vitro in rat aorta with or without endotheliumdisplayed comparable NO-independent vasorelaxant activityat antiplatelet concentrations It supports the safety of Fvulgare that is free from cytotoxic effects Anethole and Fvulgare did not cause cytotoxicity when incubated for 30minupto 300 120583gmL in platelet viability test This concentrationwas largely compatible with those adopted in the functionalin vitro tests In vivo both F vulgare essential oil andanethole orally administered in a subacute treatment to mice(30mgkgday for 5 days) showed significant antithrom-botic activity preventing the paralysis induced by collagen-epinephrine intravenous injection (70 and 83 protectionresp)Thus essential oil and its main component anethole ofF vulgare showed a safe antithrombotic activity in guinea pigplasma that seems due to their broad spectrum antiplateletactivity clot destabilizing effect and vasorelaxant action [55]

419 Antimutagenic Effect Essential oil of F vulgare revealednoteworthy protective effects against genotoxicity in mice

24 BioMed Research International

induced by cyclophosphamide Genotoxicity and cytotoxicitywere assessed by using mice bone marrow chromosomalaberration micronucleus and sperm abnormality assaysrespectively Oral administration of essential oil (1 and2mLkg) significantly inhibited the frequencies of aberrantmetaphases chromosomal aberrations micronuclei forma-tion and cytotoxicity in mouse bone marrow cells inducedby cyclophosphamide and also produced a significant reduc-tion of abnormal sperm and antagonized the reduction ofcyclophosphamide induced superoxide dismutase catalaseand glutathione activities and inhibited increased malondi-aldehyde content in the liver Additionally F vulgare inhibitsthe oxidative stress induced by cyclophosphamide [90]

420 Gastrointestinal Effect Theaqueous extract of F vulgareshowed remarkable antiulcerogenic effect against ethanol-induced gastric lesions in rats It was found that pretreatmentwith aqueous extract significantly reduced ethanol-inducedgastric damageThis effect of aqueous extract was highest andstatistically significant in 300mgkg group comparedwith thecontrol (119875 lt 0001) group of animal Additionally aqueousextract of F vulgare significantly reduced the whole bloodmalondialdehyde levels while significantly increased nitritenitrate ascorbic acid retinol and beta-carotene levels Thusaqueous extract of F vulgare fruit had clearly a protectiveeffect against ethanol-induced gastric mucosal lesion in rats[81]

421 Chemomodulatory Action The chemopreventive effectof different doses of test diet of Foeniculum vulgare seeds wasexamined against 712-dimethylbenz(a)anthracene- (DMBA-) induced skin papillomagenesis and benzo(a)pyrene-[B(a)P-] induced forestomach papillomagenesis at the peri-initiational level in Swiss albino mice Fennel seeds exhibita significant reduction in the skin and the fore-stomachtumor incidence and tumor multiplicity as compared tothe control group Further biochemical assays showeda significant increase in the contentactivities of phase Ienzymes especially in the case of 6 test diet A concomitantincrease in the activities of the phase II enzymes wasobserved with all the doses of test diet under study Asignificant enhancement in the activities of antioxidantenzymes was observed especially at 4 and 6 test diets offennel These findings were indicative of chemopreventivepotential of fennel against carcinogenesis This is the firstreport showing chemopreventive potential of seeds of fennelagainst carcinogenesis [85]

422 Cytoprotection and Antitumor Activity Anethole is theprincipal active component of fennel seeds which has exhib-ited anticancer activity Al-Harbi et al studied the antitumoractivity of anethole against Ehrlich ascites carcinoma inducedin a tumor model in Swiss albino mice The study revealedthat anethole increased survival time reduced tumor weightand reduced the volume and body weight of the Ehrlichascites tumour-bearing mice It also produced a significantcytotoxic effect in the Ehrlich ascites tumour cells in the pawreduced the levels of nucleic acids and malondialdehyde and

increased glutathione concentrations [110] In vitro cytopro-tection activity of methanolic extract of Foeniculum vulgarewas evaluated against normal human blood lymphocytes bymicronucleus assay and antitumor activity against B16F10melanoma cell line by Trypan blue exclusion assay for cellviability Lymphocyte culture treated with 70 methanolicextract of Foeniculum vulgare showed very less percentage ofmicronucleus that is 0006 as compared to standard drugdoxorubicin which showed 0018 micronucleus On theother hand 70methanolic extract of Foeniculum vulgare haspotent antitumor activity at the concentration of 200120583gmLThe results suggest that the Foeniculum vulgare could beconsidered as a natural resource of antitumor agents as wellas cytoprotective to normal cells [11]

423 Cytotoxicity Kaileh and his coworker investigated thecytotoxic effect of organic extracts of 24 selected Palestinianmedicinal plant species The plant selection was based onexisting ethnobotanic information and interviews with localhealers The extracts of the plants under investigation weretested for their potential antitumor (cytotoxic) effect on themurine fibrosarcoma L929sA cells and on the human breastcancer cells MDA-MB231 and MCF7 The extract from Fvulgare presented an IC (50) value at 24 h of 700 plusmn 28 and500plusmn17 120583gmL on L929sA andMCF7 cells respectivelyThenuclear transcription factor NFkappaB or NF120581B regulatesthe expression of various genes They further investigatedthe effect of nine promising plant extracts withheld fromthe first cell viability screening on NF120581B activation Thedichloromethane and methanol (1 1) extract of aerial part ofF vulgare revealed immunomodulatory NF120581B activities [82]Also Berrington and Lall investigated the in vitro cytotoxicityof acetone extracts of F vulgare and other eight medicinalplants against a noncancerous African green monkey kidney(Vero) cell line and an adenocarcinoma cervical cancer(HeLa) cell line [87]

424 Antipyretic Activity F vulgare extract showedantipyretic activity against hyperpyrexia in mice It wasinduced by SC administration of 2mL100 g of a 20aqueous suspension of brewerrsquos yeast As an antipyreticagent ethanolic extract of F vulgare fruit showed a moderateantipyretic activity that was statistically significant after 30and 90min (119875 lt 001) [108]

425 Hypolipidemic Activity The aqueous extract of F vul-gare revealed notable hypolipidemic and antiatherogenicactivity against Triton WR-1339 induced hyperlipidemiain mice Aqueous extract causes significant reduction ofplasma lipid levels that is cholesterol triglycerides LDL-cholesterol and apolipoprotein-B decreased by 40 2361 and 61 respectively and increase in HDL-cholesteroland apolipoprotein A1 by 85 and 58 respectively [88]

426 Hypoglycemic Activity The essential oil of F vulgareexhibits potential hypoglycemic and antioxidant activityagainst streptozotocin induced diabetes in rats Essentialoil (30mgkg body weight) of F vulgare works in the

correction of hyperglycemia from 1625 plusmn 319mgdL to8197 plusmn 197mgdL with 119875 lt 005 and the activity of serumglutathione peroxidase from 5972 plusmn 278Ug Hb to 9960 plusmn638Ug Hb with 119875 lt 005 Also essential oil of fennelimproves the pathological changes noticed in their kidneyand pancreas as compared with the control group of animalThis can prove its effect as antidiabetic in folk Medicine Thismakes the possibility of its inclusion in antidiabetic drugindustry [12]

427 Antispasmodic Activity The antispasmodic activity of25 and 100mLL of alcoholic extract of Foeniculum vulgarealong with other Germanic medicinal plants namelyMelissaofficinalis Rosmarinus officinalisMentha piperitaMatricariachamomilla Carum carvi and Citrus aurantium were testedemploying the guinea pig ileum and using acetylcholine andhistamine as spasmogens An alcoholic extract of the fruits ofFoeniculum vulgare possesses antispasmodic activity whichinhibits the acetylcholine and histamine-induced guineapig ileal contractions in vitro An essential oil which isobtained from the fruits of Foeniculum vulgare 25 120583gmL and10 120583gmL respectively inhibited oxytocin and prostaglandin[72]

428 Apoptotic Activity The apoptotic activities of ethanolextracts from fruits of seven species of Apiaceae familynamely Eryngium planum Archangelica officinalis Pasti-naca sativa Heracleum sibiricum Carum carvi Foenicu-lum vulgare and Levisticum officinale against ML-1mdashhumanacute myeloblastic leukaemia J-4501mdashhuman acute Tcell leukaemia EOLmdashhuman eosinophilic leukaemia HL-60mdashhuman Caucasian promyelocytic leukaemia 1301mdashhuman T cell leukaemia lymphoblast C-8166mdashhuman Tcell leukaemia U-266B1mdashhuman myeloma WICLmdashhumanCaucasian normal B cell and H-9mdashhuman T cell wereinvestigated with the help of Trypan blue assay and AnnexinV fluos assay [86] The ethanol extract from fruit F vulgareshowed the highest mortality in Trypan blue test for J45cell linemdash4 of viable cells and for C8166 cell linemdash100of mortality However the cells of other lines showed thehighest viability HL60mdash60 EOLmdash48 and MLmdash1ndash42The normal cell line H9 and WICL showed 35 and 25of viable cells respectively C8166 cell line and J-45 cell lineshowed the highest level of the apoptotic cells detected byAnnexin V methodmdash100 and 93 respectively Howeverthe cells of two lines HL60 and EOL-1 showed the lowerlevels of apoptotic cellsmdash52 and 60 respectively Highpercentage of apoptotic cells was observed inH9 andWICLmdash76 and 93 respectively [86]

429 Human Liver Cytochrome P450 3A4 Inhibitory ActivityThirteen compounds isolated from the methanolic extract offennel have been found to possess human liver cytochromeP450 3A4 inhibitory activity Among these compounds 5-methoxypsoralen (5-MoP) showed the strongest inhibitionwith an IC50 value of 183120583m and with a mixed type ofinhibition [83]

430 Antiaging Effects Rasul and his coworker developeda base and formulation containing 4 concentrated seedextract of F vulgare This formulation shows notable antiag-ing effect with supporting experimental data related to skinmoisture and transepidermal water loss (TEWL) The basewas insignificant while the formulation showed significanteffects on skin moisture and TEWL The texture parameterenergy showed a significant increase proving that the formu-lation possesses potential antiaging effects [50]

431 Bronchodilatory Effect Ethanol extract and essential oilfrom F vulgare exhibited bronchodilatory activity on con-tracted tracheal chains of guinea pig The potassium channelopening effect of fennel may contribute on its relaxant effecton guinea pig tracheal chains [111] Moreover anethole bearsa striking resemblance to the catecholamines epinephrinenorepinephrine and dopamine This structural similarityappears to be responsible for the various sympathomimeticactivities of F vulgare such as bronchodilatory effect [71]

432 Antioxidant Activities Naturally occurring antioxi-dants can be used to protect human beings from oxidativestress damage [112] Fennel was known as excellent source ofnatural antioxidants and contributed to the daily antioxidantdiet [113]Wild fennel was found to exhibit a free radical scav-enging activity with higher content phenolic and flavonoidthan medicinal and edible fennel and the aerial parts ofthe Italian fennel populations showed the highest DPPHscavenging activity [65] Phenolic compounds of fennelincluding caffeoylquinic acid rosmarinic acid eriodictyol-7-orutinoside quercetin-3-O-galactoside and kaempferol-3-O-glucoside showed antioxidant activities [67] The volatileoil showed strong antioxidant activity in comparison withbutyrated hydroxyanisole and butylated hydroxytolueneEthanol and water extracts of fennel showed less antioxidantactivity compared with essential oil [114]

5 Environmental Application

Foeniculum vulgare that is fennel not only exhibited phar-macological activities but also revealed a few environmentalactivities These activities play a key role in the managementof nematode insect mosquitoes and some harmful larvae ofmalaria producing vector Thus the extracts of F vulgare andisolated biologically active compounds have been evaluatedfor their insecticidal repellent acaricidal larvicidal andnematicidal activity [115ndash119] A brief review on the differenttype of ecofriendly environmental activities as reported onthis plant is summarized below

51 Insecticidal Activities The fruit derived phytoconstitu-ents of F vulgare exhibited prominent insecticidal activi-ties against Sitophilus oryzae Callosobruchus chinensis andLasioderma serricorne This activity was examined usingdirect contact application and fumigation methods Thebiologically active constituents that is phenylpropenes (E)-anethole and estragole and the monoterpene (+)-fenchonewere characterized from Foeniculum fruit By using a filter

26 BioMed Research International

paper diffusion test estragole (0168mg cmminus2) caused 91mortality to S oryzae within 1 day after treatment whereas(+)-fenchone and (E)-anethole gave over 90 mortality at 2and 4 day after treatment respectively

After 2 days of treatment all test compounds (0021mg cmminus2 concentration) revealed potent insecticidal activityagainst C chinensis Whereas after 1 day of treatment (E)-anethole (0105mg cmminus2) gave 100mortality of L serricornewhereas 90 and 60 mortality at 4 day after treatment wasachieved with estragole and (+)-fenchone respectively In afumigation test the compounds were much more effectiveagainst adults of S oryzae C chinensis and L serricorne inclosed cups than in open ones indicating that the insecticidalactivity of test compounds was largely attributable to fumi-gant action As naturally occurring insect-control agents theF vulgare fruit-derived materials described could be usefulfor managing field populations of S oryzae C chinensis andL serricorne [116]

52 Acaricidal Activity Fennel oil shows significant acaricid-al activity againstDermatophagoides farinae andDermatoph-agoides pteronyssinus (+)-fenchone and p-anisaldehyde aremajor constituents of fruit oil of F vulgare P-anisaldehydewas the most toxic compound against D farinae and is muchmore effective compared with benzyl benzoate thymol andestragol [118]

53 Repellent Activity The methanolic extract of fruits ofF vulgare was spectroscopically characterized for the pres-ence of biologically active constituents called (+)-fenchoneand (E)-9-octadecenoic acid The repellent activity of theseconstituents was tested against hungry Aedes aegypti femaleswith the help of skin and patch tests and compared withthat of the commercial repellent agent called NN-diethyl-m-toluamide (DEET) and (Z)-9-octadecenoic acid In askin test with female mosquitoes (+)-fenchone and (Z)-9-octadecenoic acid (04mgcm2) exhibitedmoderate repellentactivity at 30min after treatment whereas DEET providedgt1 h of protection against adult mosquitoes at (02mgcm2)Thus (+)-Fenchone and (E)-9-octadecenoic acid are poten-tial mosquito repellent agents or lead compounds [117]

54 Larvicidal Activity Plant extracts and oils may act asalternatives to conventional pesticides for malaria vectorcontrol By considering this aspect Sedaghat et al [119] inves-tigated the larvicidal activity of essential oils of three plantsof Apiaceae family against malaria vector called Anophe-les stephensi The larvicidal activity was evaluated againstlaboratory-reared larvae by standard method of WHO TheF vulgare oil was the most effective against A stephensiwith LC(50) and LC(90) values of 2010 and 4451 ppmrespectively [119] Additionally the essential oil extracts fromleaves flowers and roots of F vulgare exhibit noticeablelarvicidal activity against fourth-instar larvae of themosquitoCulex pipiens molestus Terpineol and 18-cineole content of Fvulgare are the most effective phytoconstituent against Culexpipiens molestus bites offering complete protection for 16 and2 h respectively [120] Recently Zoubiri et al [57] reported

the larvicidal activity of essential oil of fennel seed againstCulex pipiensmosquitoThus F vulgare can serve as a naturallarvicidal agent

55 Nematicidal Activity Oka et al investigated the in vitronematicidal activity of essential oils extracted from 27 spicesand aromatic plants in pot experiments Twelve of thetwenty-seven essential oils immobilized more than 80 ofjuveniles of the root-knot nematodeMeloidogyne javanica ata concentration of 1000 120583Lliter At this concentration mostof these oils also inhibited nematode hatching Essential oilsof Carum carvi Foeniculum vulgare Mentha rotundifoliaand Mentha spicata showed the highest nematicidal activityamong the in vitro tested oils In 3-liter pot experimentsnematicidal activity of the essential oils and their componentswas confirmed at 200 and 150mgkg respectivelyThe resultssuggest that the essential oils and theirmain componentsmayserve as nematicides [115]

6 Toxicity

The long history of ethnomedicinal application with noreports of any serious side effects suggests that F vulgarecould be considered as safe Inmost toxicity experiments car-ried out on F vulgare no sign of toxicity was observed Shahand his coworker in 1991 investigated the detailed toxicityaccount of ethanolic extract of fennel fruit in experimentalmice with respect to acute and 90 days longer term toxicity[121] In experimentation Shah and his coworker observedthe general symptoms of toxicity and mortality for only 24 hin acute toxicity Whereas in another part of toxicity theystudied the effect of fennel extract on mice with 90 dayslong term treatment Acute toxicity of ethanolic extract of Fvulgarewas assessed in 35mice by using three concentrationsnamely 05 1 and 3 gkg body weight In this investigation Fvulgare exhibited no signs of toxicity and no mortality wasobserved upto the dose level 3 gkg body weight In case oflonger term toxicity ethanolic extract of F vulgare (100mgkgbody weightday) was given in drinking water of animals(30 male and 30 female mice) All external morphologicalhaematological and spermatogenic changes in addition tobody and vital organ weights were recorded The extractcaused no significant chronic mortality as compared tocontrols during this investigation The treated male micegained significant weight during chronic treatment while aloss or no significant change in weight was noticed in thefemale mice treated with the same extract The extracts didnot show spermatotoxic effects Thus Shah and his coworkerconcluded that fennel extract is safe based on both acuteandor long term toxicity studies [121] Additionally the plantextract in doses of 05 1 and 3 gkg (orally) did not causeany deaths These doses do not show any type of toxicityagainst several parameters tested namely locomotor activitybizarre reactions sensitivity to sound social interaction tailposture aggressive behaviour ataxia paralysis convulsionstremors prostration exophthalmos pupil size defecationsalivation urination pattern of respiration nasal dischargecyanosis and piloerection Exceptionally only the 3 gkg dose

BioMed Research International 27

showed signs of reduced locomotor activity and piloerec-tion Otherwise all other parameters were negative [108]In another experiment of acute toxicity different solventextracts namely n-hexane methylene chloride ethyl acetateand methanol extracts of F vulgare upto 55 gkg concentra-tion did not revealed any kind of toxicity in mice LD50being 675 110 692 and 15 gkg for n-hexane methylenechloride ethyl acetate and methanol extracts respectively[68] The plant extract of F vulgare was administered orallyat a dose of 100 200 400 600 800 1000 and 2000mgkgof body weight of mice Each group of animals was undervisual observation for 10 days for the external behavior ofneurological toxicity created by plant extract Even the micereceiving highest dose of F vulgare extract did not show anymortality or toxicity demonstrating the safety profile of theplant extract [89]

The acute oral 50 LD50 for anethole in rats was foundto be 2090mgkg Repeated doses of one-third the LD50 ofanethole (695mgkg) given to rat caused mild liver lesionsIt would therefore appear that in normal therapeutic dosagesanethole would have minimal hepatotoxicity When anetholewas fed to rats daily for one year as 025 of the dietno hepatic damage was seen [122] The acute oral LD50 ofessential oil in rats is 1326mgkg [76] The use of F vulgareessential oil as a remedy for control of primary dysmenorrheaincreases concern about its potential teratogenicity due toits estrogen like activity Evaluation of teratogenicity ofessential oil using limb bud mesenchymal cells showed thatthe essential oil may have toxic effect on fetal cells butthere was no evidence of teratogenicity upto concentrationof 93mgmL of culture medium [123] The overall toxicitystudies carried out on F vulgare accounts for its safety at therecommended therapeutic doses

7 Conclusions

The available scientific research on Foeniculum vulgarehas shown that it is an important medicinal plant used ina wide range of ethnomedical treatments especially forabdominal pains antiemetic aperitif arthritis cancer colicin children conjunctivitis constipation depurative diarrheadieresis emmenagogue fever flatulence gastralgia gastritisinsomnia irritable colon kidney ailments as a laxativeleucorrhoea liver pain mouth ulcer and stomachache Thisplant has been in use for a long period of time withoutany documented serious adverse effects Studies carriedout in the past and present indicate that fennel possessesdiverse health benefits and are an important constituentof food Studies have shown that various extracts offennel possess a range of pharmacological actions such asantiaging antiallergic anticolitic antihirsutism anti-inflam-matory antimicrobial and antiviral antimutagenic antino-ciceptive antipyretic antispasmodic antistress antithromb-otic anxiolytic apoptotic cardiovascular chemomodulatoryaction cytoprotection and antitumor cytotoxicity diureticestrogenic properties expectorant galactogenic gastrointes-tinal effect hepatoprotective human liver cytochrome P4503A4 inhibitory hypoglycemic hypolipidemic memory-en-hancing property nootropic and oculohypotensive activity

supporting its traditional use However the most prominentand the well studied effects are the antimicrobial andantioxidant effects of essential oil of fennel in differentexperimental models The observed health benefits may becredited to the presence of the various phytochemicals likevolatile compounds flavonoids phenolic compounds fattyacids and amino acids

Fennel also contains mineral and trace elements likealuminum barium calcium cadmium cobalt chromiumcopper ironmagnesiummanganese nickel lead strontiumand zinc [124] fat soluble vitamins such as vitamins A Eand K water soluble vitamins like ascorbic acid thiamineriboflavin niacin and pyridoxine essential amino acidslike leucine isoleucine phenylalanine and tryptophane maycontribute to the myriad health beneficial effects at least inpart

Most of the pharmacological studies were conductedusing uncharacterized crude extracts of fennel It is difficultto reproduce the results of these studies and pinpoint thebioactive compounds Hence there is a need for chemi-cal standardization and bioactivity-guided identification ofbioactive compounds Among several classes of chemicalconstituents identified in fennel volatile components of fen-nel essential oil and phenolic compounds are assumed to bethe main bioactive compounds responsible for the majorityof its pharmacological effects However the vast traditionaluse and proven pharmacological activities of fennel indicatethat an immense scope still exists for its chemical explorationFuture studies should be focused on validating the mecha-nism of action responsible for the various beneficial effectsand also on understanding which plant based compounds areresponsible for the reported effectsThe required informationwhen available will enhance our knowledge and appreciationfor the use of fennel in our daily diet Also the outcomeof such chemical studies may further expand its existingtherapeutic potential

Thus there are many areas of research related to thisplant that need to be further explored to fully recognize itsbeneficial effects for society Factors such as geographical andseasonal variation play an important role in the authentica-tion of the chemical constituents responsible for the activitywhich also can be an area of interest Thus it is incumbenton researchers to fill the huge gap of insufficient knowledgeand create awareness among pharmacologists as well as inves-tigators towards providing better medicinal value derivedfrom this plant This can be fulfilled only by generatinginterest among the research community through writing ofcritical appraisals (paper) and extending the interdisciplinaryresearch area to focused studies on Foeniculum vulgare

They are greenish-yellow the colour of hay from which theterm fennel is derived Wild fruits are short dark colouredand blunt at their ends and have a less agreeable flavourand odour than those of sweet fennel Seeds ripen fromSeptember to October This plant can reproduce from crownor root fragments but freely reproduces from seed

13 Chemical Composition and Nutritional Value of FennelFoeniculum vulgare is widely grown for its edible fruit orseeds These are sweet and dry a fully ripe specimen isan exquisite fruit The fruit is often dried for later use andthis dried fruit called fennel is a major item of commerceTable 2 lists the nutrient composition of fennel (USDA data)Fennels are one of the highest plant sources of potassiumsodium phosphorus and calcium According to USDA datafor the Mission variety fennels are richest in dietary fiberand vitamins relative to human needs They have smalleramounts of many other nutrients

Table 3 summarizes the chemical composition andthe nutritional value [14] of different parts of fennelnamely shoots leaves stems and inflorescence Leavesand stems show the highest moisture content (7636 and7746 g100 g resp) while inflorescence exhibits the lowestcontent (7131 g100 g) Carbohydrates are the most abundantmacronutrients in all the parts and range from 1844 to2282 g100 g Proteins reducing sugars and fats are theless abundant macronutrients proteins varied between108 g100 g in stems and 137 g100 g in inflorescences Theinflorescences and stems revealed the highest fat content(128 g100 g) and reducing sugar content (149 g100 g)respectively amongst all the parts of fennel On the basisof the proximate analysis it can be calculated that a freshportion of 100 g of these parts yields on average 94Kcal of

energy The highest values were obtained for inflorescenceswhile leaves and stems gave the lowest energy contribution

About twenty-one fatty acids were identified and quanti-fied from the abovementioned parts of fennel (Table 3)Theseare caproic acid caprylic acid capric acid undecanoic acidlauric acid myristic acid myristoleic acid pentadecanoicacid palmitic acid heptadecanoic acid stearic acid oleicacid linoleic acid 120572-linolenic acid arachidic acid eicosanoicacid cis-1114-eicosadienoic acid cis-111417-eicosatrienoicacid + heneicosanoic acid behenic acid tricosanoic acidand lignoceric acid Thus Barros and his coworker concludepolyunsaturated fatty acids (PUFA) to be the main groupof fatty acids present in all the fennel parts On the otherhand Vardavas and his coworker reported monounsaturatedfatty acids (MUFA) as the main group of fatty acids infennel [22] Nevertheless unsaturated fatty acids (UFA) rangefrom 66 to 80 and predominate over saturated fatty acids[14] The highest concentration of n-3 fatty acids was foundin fennel leaves while the lowest concentration was found

in inflorescences The ratio of 1205966 to 1205963 fatty acids has animportant role in the human diet The highest levels of n-3fatty acids found in leaves contributed to its lowest ratio of1205966 to 1205963 fatty acids The lowest levels of n-3 fatty acids foundin inflorescences contributed to its highest ratio of 1205966 to 1205963fatty acids

Fennels have smaller amounts of many other nutrientsOn a weight basis fennels contain more calcium (49mg100 g) as compared with apples (714mg100 g) bananas(388mg100 g) dates (250mg100 g) grapes (1086mg100 g) orange (4025mg100 g) prunes (180mg100 g) rais-ins (400mg100 g) and strawberries (1401mg100 g) Phe-nolics are an important constituent of fruit quality becauseof their contribution to the taste colour and nutritionalproperties of fruit Amongst the phenolics analyzed in thefruit of this plant are neochlorogenic acid (140) chloro-genic acid (298) gallic acid (0169) chlorogenic acid(6873) caffeic acid (2960) p-coumaric acid (4325)ferulic acid-7-o-glucoside (5223) quercetin-7-o-glucoside

Thus as a typical seasonal fresh fruit fennels are animportant constituent of the regional diet of Europe and otherregions Different varieties of fennel parts are widely used inmany of the cooking dishes all over world (Table 4) Shootstender leaves and stems are chewed and sucked due to theirexquisite aniseed flavor All these parts are also commonlyused as vegetables They are added raw to salads stewedwith beans and chickpeas used to stuff fish for grilling

and placed in soups and bread bouillons Besides seasoningfennel is used to preserve food Flowering stems sugar andhoneymacerating in brandy produce a highly valorized spiritHerbal teas prepared with fresh tender or dried floweringstems are consumed chilled or hot depending on the seasonF vulgare is famous for its essential oil The characteristicanise odour of F vulgare which is due to its essential oilmakes it an excellent flavoring agent in baked goods meatand fish dishes ice-cream and alcoholic beverages Theculinary uses of fennel are so diversewidespread that it hasbeen exported from country to country for centuries [14]

2 Traditional and Contemporary Uses

41 Antimicrobial and Antiviral Activities Foeniculum vul-gare has been used as an ethnic remedy for the cure ofnumerous infectious disorders of bacterial fungal viral andmycobacterial origin Several studies have been carried outin the past validating its antimicrobial antimycobacterialand antiviral potential (summarized in the Table 9) Duskoet al [91] investigated the antibacterial effect of the aqueousextract of 12 medicinal plants of Apiaceae family includingF vulgare An aqueous extract of the aerial part of Fvulgare inhibited the growth of Agrobacterium radiobacterpv tumefaciensErwinia carotovoraPseudomonas fluorescensand Pseudomonas glycinea (Table 9) An aqueous extract ofseed sample inhibited the growth of Enterococcus faecalisStaphylococcus aureus Escherichia coli Klebsiella pneumo-nia Pseudomona aeruginosa Salmonella typhi Salmonellatyphimurium Shigella flexneri and Bacillus cereus with 13ndash22 22ndash24 14ndash24 20-21 21ndash24 11-12 14ndash18 17ndash18 and 24ndash26mm zone of inhibition respectively [3 4] Gulfraz et al[92] investigated the antibacterial effect of the essential oil aswell as ethanolic and methanolic fruit extracts of F vulgareagainst Bacillus cereus Bacillus megaterium Bacillus pumilus

Bacillus subtilis Escherichia coliKlebsiella pneumoniaMicro-coccus luteus Pseudomonas putida Pseudomonas syringaeand Candida albicans According to the results reported byGulfraz et al [92] essential oil of F vulage had significantantimicrobial activities against some of microorganisms ascompared to the methanolic and ethanolic extracts Thediameters of growth inhibition zone ranged from 14 to 31mm(including the diameter of the disc 6mm) with the highestinhibition zone values observed against Bacillus megaterium(31mm) and Bacillus subtilis (29mm) Roby et al [23]investigated antimicrobial effect of the methanol ethanoldiethyl ether and hexane extracts of seed of F vulgare againsttwo species of Gram negative bacteria (Escherichia coli andSalmonella typhi) two species of Gram positive bacteria(Bacillus cereus and Staphylococcus aureus) one species ofyeast (Candida albicans) and one species ofmold (Aspergillusflavus)Themethanolic extract showedmore effective antimi-crobial activity than the other extracts The results fromthe disc diffusion method followed by measurement ofminimum inhibitory concentration (MIC) indicated thatBacillus cereus and Aspergillus flavus were the most sensitivemicroorganisms tested showing the largest inhibition zonesand the lowest MIC values Least activity was exhibitedagainstEscherichia coli with the smallest inhibition zones andthe highest MIC value [23] Shrivastava and Bhargava [93]investigated the antibacterial effect of the crude chloroformand methanol extract of leaves and flowers of F vulgarealong with Raphanus sativus and Brassica nigrum againstEscherichia coli and Staphylococcus aureus Methanol extractof flower of F vulgare showed significant activity againstEscherichia coli whereas crude and chloroform extractsfailed to exhibit antimicrobial activity against Staphylococcusaureus (Table 9) Among different tested bacterial strains the

methanolic fruit extract of F vulgare inhibited the growthof Staphylococcus aureus and Bacillus pumilus with 1127 and1267mm zone of inhibition respectively [7]

Several studies indicating the antifungal effect of Fvulgare along with antibacterial effect are also reported inthe literature Martins et al [94] investigated the antibacterialand antifungal effects of three essential oils of Portugueseplants namely Foeniculum vulgareMentha spicata and Ros-marinus officinalis against Staphylococcus aureus Escherichiacoli Klebsiella pneumonia Pseudomona aeruginosa Staphy-lococcus epidermidis Candida albicans and phytopathogenic

diseases [97] In an in vitro study aqueous and alcoholicseed extracts of F vulgare exhibited inhibitory effect againstAlternaria alternata Mucor rouxii and Aspergillus flavus[98] Interestingly aqueous seed extract of F vulgare showedstrongest antifungal activity as compared to reference fungi-cidal agent that is griseofulvin [99]

All of the above mentioned studies were carried outon the crude extracts and it is difficult to pinpoint theactive antimicrobial metabolite A phenylpropanoid deriva-tive called dillapional characterized from F vulgare stem wasfound to be an antimicrobial constituent with MIC values of125 250 and 125 against Bacillus subtilis Aspergillus nigerand Cladosporium cladosporioides respectively A coumarinderivative scopoletin was also isolated as a marginallyantimicrobial agent [100] The characterization of sevendifferent types of oxygenatedmonoterpenes frommethylene

chloride crude extract of F vulgare [101] suggested thatthe crude extract containing monoterpenes could be a newmedicinal resource for antibacterial agents

A total of 78 compounds were identified from theactive antimycobacterial fraction of F vulgare with thehelp of gas chromatography-mass spectra (GC-MS) Outof these twenty compounds were tested against one sensi-tive and three MDR strains of Mycobacterium tuberculosisusing the Alamar Blue microassay Compounds that showedsome degree of antimycobacterial activity against all strainstested were the following linoleic acid (MIC 100 120583gmL)oleic acid (MIC 100 120583gmL) 13-benzenediol (MIC 100ndash200120583gmL) undecanal (MIC 50ndash200120583gmL) and 24-undecadienal (MIC 25ndash50120583gmL) 24-Undecadienal wasthe most active compound against multidrug resistant Mtuberculosis speciesThus the dietary intake of F vulgaremaylower the risk ofM tuberculosis infection [63]

Orhan et al [5] studied the antiviral activity of theessential oil of fruit sample of F vulgare along with 12other Turkish medicinal plants against the DNA virusHerpessimplex type-1 (HSV-1) and the RNA virus parainfluenzatype-3 (PI-3) Most of the oils and compounds displayedstrong antiviral effects against HSV-1 ranging between 08and 0025 120583gmL However the samples tested were lesseffective against PI-3 with results ranging between 16 and02 120583gmL Only the essential oils of Anethum graveolensFoeniculum vulgare (fully mature) Mentha piperita Menthaspicata Ocimum minutiflorum Ocimum vulgaris and Sat-ureja cuneifolia inhibited this virus significantly

All these literature findings validated the traditional usesof Foeniculum vulgare in infectious disorders like abdomi-nal pains antiemetic arthritis conjunctivitis constipationdepurative diarrhea dieresis fever flatulence gastralgia gas-tritis insomnia irritable colon mouth ulcer stomachacherespiratory disorders skin diseases and so forth There isalways a need for new antimicrobial agents due to rapiddevelopment of resistance Bioactive metabolites of F vulgaremay be a potential source for new antimicrobial agents

42 Anti-Inflammatory Activity Oral administration ofmethanol extract of F vulgare fruit to rat and mice exhibitedinhibitory effects against acute and subacute inflammatorydiseases The anti-inflammatory activity of methanol extractwas evaluated by using three screening protocols namelycarrageenan-induced paw edema arachidonic acid-inducedear edema and formaldehyde-induced arthritis Theseare widely used for testing nonsteroidal anti-inflammatorydrugs For acute inflammationmethanol extract (200mgkg)exhibits significant inhibition of paw edema (69) inducedby carrageenan injection as compared to the control groupof animals Methanol extract of F vulgare also inhibitsear-edema (70) induced by arachidonic acid in mice Thelevel of serum transaminase aspartate aminotransferase(AST) and alanine aminotransferase (ALT) significantlyincreases in the presence of methanolic extract of F vulgareon inflammation induced by formaldehyde as comparedto control group The assessment of the level of AST and

ALT provides a good and simple tool to measure the anti-inflammatory activity of the target compounds [102] Theseoverall results seem to suggest that F vulgare FME mayact on both the cyclooxygenase and lipoxygenase pathways[79]

43 Antiallergic Activity Methanolic extract of F vulgarefruit showed significant inhibitory effect on DNFB- (24-dinitrofluorobenzene-) induced delayed type hypersensitiv-ity after oral administration of 200mgkg once a day for7 days The inhibitory effect on immunologically inducedswelling suggests the possible immunosuppressive propertiesof F vulgare [79]

44 Hepatoprotective Activity Essential oil of F vulgareseeds revealed a potent hepatoprotective effect against acutehepatotoxicity produced by carbon tetrachloride in ratsOral administration of F vulgare essential oil decreases thelevels of serum aspartate aminotransferase (AST) alanineaminotransferase (ALT) alkaline phosphatase (ALP) andbilirubin as compared to the control group Ozbek et alsuggest that the constituents (d-limonene and 120573-myrcene) ofessential oil may have played a key role in the protection ofliver from CCl

4toxicity [9]

45 Anxiolytic Activity Anxiety is the unpleasant feeling offear and concern When anxiety becomes excessive it maybe considered as an anxiety disorder Anxiolytic fennel isa drug used for the treatment of anxiety and its relatedpsychological and physical symptoms Naga Kishore et al[89] investigated the anxiolytic activity of ethanolic extract ofF vulgare fruit with the help of elevated plus maze rota rodopen field test and whole board models The 100 to 200mgdose of extract per kg of body weight of animal revealedsignificant activity when compared to reference anxiolyticdrug called diazepam (1mgkg) Thus fennel extract maypossess anxiolytic activity supporting its traditional claimabout anxiolytic activity reported in 19th edition of Pharma-cology and Pharmacotherapeutics by Sathodkar Bhandarkarand Rege

46 Antistress Activity Drug and food of natural originplay a significant role in public healthcare systems and arebeing investigated as remedies for a number of stress-relateddisorders [103]Thewhole plant extract of F vulgare exhibitednotable antistress effect against stress induced by forcefulswimming of test animals The key parameters that isurinary levels of vanillyl mandelic acid (VMA) and ascorbicacid in rats were used to evaluate antistress activity Theplant extract (50 100 and 200mgkg body weight) showeda significant improvement in urinary levels of VMA (119875 lt0001) and ascorbic acid excretion levels (119875 lt 0001) in testanimals when compared to the normal basal levels in controlgroup of animalsThus the extract of entire plant of F vulgareacts as an antistress agent [13]

47 Memory-Enhancing Property There are a number ofplants whose consumption is believed to enhance memory

22 BioMed Research International

and intelligence These were usually given to children as partof their food F vulgaris an ayurvedic rasayana (mixture)possessing multiple neuropharmacological activities Theantidepressant activity of fennel has been well documentedin ethnomedicine The whole plants extract (50 100 and200mgkg) of F vulgare exhibited memory-enhancing effectagainst scopolamine-induced amnesic rats This experimentwas evaluated by conditioned avoidance response (CAR)technique The CAR of rats administered with the extractincreased gradually to 95 over 7 to 12 days The acquisition(time to achieve 95 CAR) for rats administered with theextract was dose- and time-dependent compared to controlgroup which took 12 days for acquisition The percentavoidance was always higher in the extract-treated groupsas compared to control group Animals receiving 200mgkgbody weight of the extract took ten days while groups treatedwith 100 and 50mgkg doses of the extract required elevenand twelve days respectively to reach the point of acquisitionAdministration of scopolamine produced amnesia as seenfrom reduction in the observed CAR Amnesia was greaterin the control group than in extract-treated groups How-ever continued treatment with F vulgare produced betterretention and recovery in a dose-dependent manner thanthe vehicle-treated animals Recovery from scopolamine-induced amnesia in the extract-treated groups took 3ndash5 dayswhen compared to normal (control) group which took over6 days This overall progress suggests that F vulgare extractpossesses memory-enhancing property [13]

48 Nootropic Activity Alzheimerrsquos disease is a neurode-generative disorder associated with a decline in cognitiveabilities Dementia is one of the age-related mental problemsand a characteristic symptom of Alzheimerrsquos disease Thereis some evidence in favor of use of F vulgare for the treat-ment of cognitive disorders like dementia and Alzheimerrsquosdisease Methanol extract of the whole plant of F vul-gare administered for eight successive days ameliorated theamnesic effect of scopolamine and aging-induced memorydeficits inmiceThis extract increased step-down latency andacetylcholinesterase inhibition in mice significantly Thus Fvulgaremay be employed in treatment of cognitive disorderssuch as dementia and Alzheimerrsquos disease as a nootropic andanticholinesterase agent [80]

49 Antihirsutism Activity Idiopathic hirsutism is definedas the occurrence of excessive male pattern hair growth inwomen who have a normal ovulatory menstrual cycle andnormal levels of serum androgens It may be a disorder ofperipheral androgen metabolism Traditionally Foeniculumvulgare has been used as an estrogenic agent It has beenreputed to increase milk secretion promote menstruationfacilitate birth and increase libido On considering aboveaspect Javidnia and his research team evaluated the antihir-sutism activity of ethanolic extract of F vulgare seed againstidiopathic hirsutism by preparing cream containing 1 and 2of fennel extract The efficacy of treatment with the creamcontaining 2 fennel is better than the cream containing 1fennel and these two were more potent than placebo (control

group) The mean values of hair diameter reduction were78 183 and minus05 for patients receiving the creamscontaining 1 2 and 0 (placebo) respectively [78]

410 Estrogenic Properties Since the discovery of the estrusinducing effects of some plant products in 1926 consider-able effort has been devoted towards the characterizationof phytoestrogens including flavonoids isoflavonoids chal-cones coumestans stilbenes lignans saponins and essentialoils [16] F vulgare has estrogen-like activity In male ratstotal concentration of protein was found to be significantlydecreased in testes and in vasa deferentia whereas increasedin seminal vesicles and in prostate gland On the otherhand simultaneous decrease in the activities of acid andalkaline phosphatase in all these regions (except that alka-line phosphatase was unchanged in vasa) due to the oraladministration of acetone extract of F vulgare fruit wasobserved In female rats oral administration of the extract for10 days led to vaginal cornification and oestrus cycle [8] Totalconcentration of nucleic acids and protein as well as the organweights increased in both the tissues namely mammaryglands and oviducts due to the oral administration of acetoneextract (50 150 and 250120583g100 g body wt) of F vulgare seeds[104] Fennel oil was reported to exhibit estrogenic activitypromote menstruation and alleviate the symptoms of femaleclimacteric and increase libido [71] Administration of fenneloil (25 and 50 120583gmL final concentration in the organ bath)failed to exhibit any remarkable effect in uterine contrac-tion While 10 20 and 40 120583gml concentration of fennel oilrevealed significant inhibitory effect against prostaglandinE2 Fennel oil significantly reduces the frequency of uterinecontraction induced by prostaglandin E2 Thus the extractsof F vulgare have strong estrogenic activity [76]

411 Galactogenic Activity Foeniculum vulgare has been usedformillennia to increasemilk secretion [105]Thus F vulgarebelongs to galactagogue substance Structural similarity ofits main constituent anethole to dopamine seems to beresponsible for galactogenic activityDopamine acts to inhibitthe secretion of the milk-producing hormone prolactinAnethole might influence milk secretion by competing withdopamine at the appropriate receptor sites thereby inhibitingthe antisecretory action of dopamine on prolactin [71] It wasreported that anol (demethylated anethole) causes growthof the lobule-alveolar system in the mammary glands ofimmature female rabbits and induces menstruation in miceand other experimental animals Anol also gave positiveresults in the Jadassohn nipple test a test which involvesthe measurement of changes induced in the nipples ofguinea pigs subjected to the cutaneous application of sexhormones However further research suggests that the actualpharmacologically active agents responsible for galactogenicactivity are polymers of anethole such as dianethole andphotoanethole rather than anol or anethole itself [20 76]

412 Expectorant Activity F vulgare seeds stimulate theciliary motility of the respiratory apparatus and enhance the

BioMed Research International 23

external transport of extraneous corpuscles This action sug-gests a use for fennel in treating bronchial and bronchopul-monary afflictions and in particularly polluted environments[106] The volatile oil of F vulgare stimulates the contractionof the smooth muscles of the trachea an action that couldfacilitate the expectoration of mucus bacteria and othercorpuscles extraneous to the respiratory tracts [74]

413 Anticolitic Activity Essential oil of fennel regulates themotility of smooth muscles of the intestine while at thesame time reducing intestinal gas Alone or combined withother plant medicinals Foeniculum vulgare is indicated in thetreatment of spastic gastrointestinal disturbances in someforms of chronic colitis (which resist other treatments) indyspepsias from gastrointestinal atony in dyspepsias withthe sensation of heaviness in the stomach and so forthTheaddition of fennel to preparations containing anthraquinoniccomponents reduces the occurrence of abdominal pain oftenassociated with this type of laxative [73]

414 Antinociceptive Activity Antinociceptive means anysubstance that inhibits nociception which is a physiologicalprocess underlying the sensation of pain Briefly it reducesthe sensitivity to painful stimuli The various extracts ofaerial part of F vulgare namely hexane methylene chlorideethyl acetate and methanolic extract showed remarkableantinociceptive activity against acetic acid induced writhingin mice [68] The methanolic extract of the aerial parts ofF vulgare exhibited the highest antinociceptive activity at adose level of 2000mgkg while the activity exhibited by theethyl acetate extract was at dose level 800mgkgOn the otherhand n-hexane extract (700mgkg) and methylene chlorideextract (500mgkg) exhibited similar antinociceptive activi-ties being less than peripheral antinociceptive reference drug(acetyl salicylic acid) [68]

415 Diuretic Activity A diuretic is any substance thatpromotes the production of urine Briefly it is an agentthat promotes diuresis Diuretics work by promoting theexpulsion of urine (measured as the urine volume [UV]excreted) and urinary sodium (UNa) from the body and thishelps reduce the volume of blood circulating through thecardiovascular system Caceres et al [107] performed a studyin conscious animals and administered a powdered extractof the whole plant (F vulgare) which had no effect on UVor UNa The ethanolic extract of F vulgare fruit revealedexcellent diuretic activity and proves the earlier folk claimof F vulgare which was reported in the United State ofAmerica (Table 5) The fruit extract showed statistically ahighly significant diuretic effect F vulgare induced diuresis(500mgkg dose)was comparable to that of reference diureticagent urea (960mgkg dose) in mice with a urine outputthat was almost double that of the control group Thediuresis was not associated with changes in sodium andorpotassium excretion [108] In another part of the study theauthors showed that Foeniculum vulgare had little effect onthe noradrenalin contractile responses of aortic rings thus

suggesting that it worked mainly as a diuretic and natriureticwith little effect on arterial vascular tone [77]

416 Cardiovascular Activity An aqueous extract of F vul-gare leaves possesses potential cardiovascular action Thiseffect was investigated using pentobarbital-anaesthetisedmale albino Sprague-Dawley rats [75] An intravenousadministration of the lyophilized boiled water extract ofleaves produced a significant dose-related reduction in arte-rial blood pressure without affecting the heart rate or respi-ratory rate On the other hand the nonboiled aqueous extractshowed very little hypotensive activityThe hypotensive effectof the boiling water extract appeared not to be mediated viaadrenergicmuscarinic ganglionic or serotonergic receptorshowever histamine antagonists inhibited the hypotensiveeffect in a dose-related manner [75]

417 Oculohypotensive Activity The aqueous seed extract ofF vulgare demonstrated significant oculohypotensive activityusing water loading and steroid induced glaucoma modelThis extract exhibited 1749 2116 and 2203 reduction ofintraocular pressure in normotensive rabbits at 03 06and 12 (wv) concentrations respectively A maximummean difference of 3120 was observed between vehiclestreated and extracts treated eyes in water loading experi-mental animal model while a maximum mean intraocularpressure lowering of 3129 was observed in steroid inducedmodel of glaucoma Thus the aqueous extract of F vulgarerevealed oculohypotensive activity which was found to be asgood as that of reference standard antiglaucoma drugs calledtimolol [84]

418 Antithrombotic Activity Tognolini et al [55] providedevidence of potent inhibitory activity of essential oil of F vul-gare against platelet aggregation induced byADP arachidonicacid and collagen in guinea pig plasma Similar findingswere reported by Yoshioka and Tamada [109] for aggregationof rabbit platelets by an aromatic factor of fennel oil Theessential oil and anethole (a constituent of oil) of F vulgaretested in vitro in rat aorta with or without endotheliumdisplayed comparable NO-independent vasorelaxant activityat antiplatelet concentrations It supports the safety of Fvulgare that is free from cytotoxic effects Anethole and Fvulgare did not cause cytotoxicity when incubated for 30minupto 300 120583gmL in platelet viability test This concentrationwas largely compatible with those adopted in the functionalin vitro tests In vivo both F vulgare essential oil andanethole orally administered in a subacute treatment to mice(30mgkgday for 5 days) showed significant antithrom-botic activity preventing the paralysis induced by collagen-epinephrine intravenous injection (70 and 83 protectionresp)Thus essential oil and its main component anethole ofF vulgare showed a safe antithrombotic activity in guinea pigplasma that seems due to their broad spectrum antiplateletactivity clot destabilizing effect and vasorelaxant action [55]

419 Antimutagenic Effect Essential oil of F vulgare revealednoteworthy protective effects against genotoxicity in mice

24 BioMed Research International

induced by cyclophosphamide Genotoxicity and cytotoxicitywere assessed by using mice bone marrow chromosomalaberration micronucleus and sperm abnormality assaysrespectively Oral administration of essential oil (1 and2mLkg) significantly inhibited the frequencies of aberrantmetaphases chromosomal aberrations micronuclei forma-tion and cytotoxicity in mouse bone marrow cells inducedby cyclophosphamide and also produced a significant reduc-tion of abnormal sperm and antagonized the reduction ofcyclophosphamide induced superoxide dismutase catalaseand glutathione activities and inhibited increased malondi-aldehyde content in the liver Additionally F vulgare inhibitsthe oxidative stress induced by cyclophosphamide [90]

420 Gastrointestinal Effect Theaqueous extract of F vulgareshowed remarkable antiulcerogenic effect against ethanol-induced gastric lesions in rats It was found that pretreatmentwith aqueous extract significantly reduced ethanol-inducedgastric damageThis effect of aqueous extract was highest andstatistically significant in 300mgkg group comparedwith thecontrol (119875 lt 0001) group of animal Additionally aqueousextract of F vulgare significantly reduced the whole bloodmalondialdehyde levels while significantly increased nitritenitrate ascorbic acid retinol and beta-carotene levels Thusaqueous extract of F vulgare fruit had clearly a protectiveeffect against ethanol-induced gastric mucosal lesion in rats[81]

421 Chemomodulatory Action The chemopreventive effectof different doses of test diet of Foeniculum vulgare seeds wasexamined against 712-dimethylbenz(a)anthracene- (DMBA-) induced skin papillomagenesis and benzo(a)pyrene-[B(a)P-] induced forestomach papillomagenesis at the peri-initiational level in Swiss albino mice Fennel seeds exhibita significant reduction in the skin and the fore-stomachtumor incidence and tumor multiplicity as compared tothe control group Further biochemical assays showeda significant increase in the contentactivities of phase Ienzymes especially in the case of 6 test diet A concomitantincrease in the activities of the phase II enzymes wasobserved with all the doses of test diet under study Asignificant enhancement in the activities of antioxidantenzymes was observed especially at 4 and 6 test diets offennel These findings were indicative of chemopreventivepotential of fennel against carcinogenesis This is the firstreport showing chemopreventive potential of seeds of fennelagainst carcinogenesis [85]

422 Cytoprotection and Antitumor Activity Anethole is theprincipal active component of fennel seeds which has exhib-ited anticancer activity Al-Harbi et al studied the antitumoractivity of anethole against Ehrlich ascites carcinoma inducedin a tumor model in Swiss albino mice The study revealedthat anethole increased survival time reduced tumor weightand reduced the volume and body weight of the Ehrlichascites tumour-bearing mice It also produced a significantcytotoxic effect in the Ehrlich ascites tumour cells in the pawreduced the levels of nucleic acids and malondialdehyde and

increased glutathione concentrations [110] In vitro cytopro-tection activity of methanolic extract of Foeniculum vulgarewas evaluated against normal human blood lymphocytes bymicronucleus assay and antitumor activity against B16F10melanoma cell line by Trypan blue exclusion assay for cellviability Lymphocyte culture treated with 70 methanolicextract of Foeniculum vulgare showed very less percentage ofmicronucleus that is 0006 as compared to standard drugdoxorubicin which showed 0018 micronucleus On theother hand 70methanolic extract of Foeniculum vulgare haspotent antitumor activity at the concentration of 200120583gmLThe results suggest that the Foeniculum vulgare could beconsidered as a natural resource of antitumor agents as wellas cytoprotective to normal cells [11]

423 Cytotoxicity Kaileh and his coworker investigated thecytotoxic effect of organic extracts of 24 selected Palestinianmedicinal plant species The plant selection was based onexisting ethnobotanic information and interviews with localhealers The extracts of the plants under investigation weretested for their potential antitumor (cytotoxic) effect on themurine fibrosarcoma L929sA cells and on the human breastcancer cells MDA-MB231 and MCF7 The extract from Fvulgare presented an IC (50) value at 24 h of 700 plusmn 28 and500plusmn17 120583gmL on L929sA andMCF7 cells respectivelyThenuclear transcription factor NFkappaB or NF120581B regulatesthe expression of various genes They further investigatedthe effect of nine promising plant extracts withheld fromthe first cell viability screening on NF120581B activation Thedichloromethane and methanol (1 1) extract of aerial part ofF vulgare revealed immunomodulatory NF120581B activities [82]Also Berrington and Lall investigated the in vitro cytotoxicityof acetone extracts of F vulgare and other eight medicinalplants against a noncancerous African green monkey kidney(Vero) cell line and an adenocarcinoma cervical cancer(HeLa) cell line [87]

424 Antipyretic Activity F vulgare extract showedantipyretic activity against hyperpyrexia in mice It wasinduced by SC administration of 2mL100 g of a 20aqueous suspension of brewerrsquos yeast As an antipyreticagent ethanolic extract of F vulgare fruit showed a moderateantipyretic activity that was statistically significant after 30and 90min (119875 lt 001) [108]

425 Hypolipidemic Activity The aqueous extract of F vul-gare revealed notable hypolipidemic and antiatherogenicactivity against Triton WR-1339 induced hyperlipidemiain mice Aqueous extract causes significant reduction ofplasma lipid levels that is cholesterol triglycerides LDL-cholesterol and apolipoprotein-B decreased by 40 2361 and 61 respectively and increase in HDL-cholesteroland apolipoprotein A1 by 85 and 58 respectively [88]

426 Hypoglycemic Activity The essential oil of F vulgareexhibits potential hypoglycemic and antioxidant activityagainst streptozotocin induced diabetes in rats Essentialoil (30mgkg body weight) of F vulgare works in the

correction of hyperglycemia from 1625 plusmn 319mgdL to8197 plusmn 197mgdL with 119875 lt 005 and the activity of serumglutathione peroxidase from 5972 plusmn 278Ug Hb to 9960 plusmn638Ug Hb with 119875 lt 005 Also essential oil of fennelimproves the pathological changes noticed in their kidneyand pancreas as compared with the control group of animalThis can prove its effect as antidiabetic in folk Medicine Thismakes the possibility of its inclusion in antidiabetic drugindustry [12]

427 Antispasmodic Activity The antispasmodic activity of25 and 100mLL of alcoholic extract of Foeniculum vulgarealong with other Germanic medicinal plants namelyMelissaofficinalis Rosmarinus officinalisMentha piperitaMatricariachamomilla Carum carvi and Citrus aurantium were testedemploying the guinea pig ileum and using acetylcholine andhistamine as spasmogens An alcoholic extract of the fruits ofFoeniculum vulgare possesses antispasmodic activity whichinhibits the acetylcholine and histamine-induced guineapig ileal contractions in vitro An essential oil which isobtained from the fruits of Foeniculum vulgare 25 120583gmL and10 120583gmL respectively inhibited oxytocin and prostaglandin[72]

428 Apoptotic Activity The apoptotic activities of ethanolextracts from fruits of seven species of Apiaceae familynamely Eryngium planum Archangelica officinalis Pasti-naca sativa Heracleum sibiricum Carum carvi Foenicu-lum vulgare and Levisticum officinale against ML-1mdashhumanacute myeloblastic leukaemia J-4501mdashhuman acute Tcell leukaemia EOLmdashhuman eosinophilic leukaemia HL-60mdashhuman Caucasian promyelocytic leukaemia 1301mdashhuman T cell leukaemia lymphoblast C-8166mdashhuman Tcell leukaemia U-266B1mdashhuman myeloma WICLmdashhumanCaucasian normal B cell and H-9mdashhuman T cell wereinvestigated with the help of Trypan blue assay and AnnexinV fluos assay [86] The ethanol extract from fruit F vulgareshowed the highest mortality in Trypan blue test for J45cell linemdash4 of viable cells and for C8166 cell linemdash100of mortality However the cells of other lines showed thehighest viability HL60mdash60 EOLmdash48 and MLmdash1ndash42The normal cell line H9 and WICL showed 35 and 25of viable cells respectively C8166 cell line and J-45 cell lineshowed the highest level of the apoptotic cells detected byAnnexin V methodmdash100 and 93 respectively Howeverthe cells of two lines HL60 and EOL-1 showed the lowerlevels of apoptotic cellsmdash52 and 60 respectively Highpercentage of apoptotic cells was observed inH9 andWICLmdash76 and 93 respectively [86]

429 Human Liver Cytochrome P450 3A4 Inhibitory ActivityThirteen compounds isolated from the methanolic extract offennel have been found to possess human liver cytochromeP450 3A4 inhibitory activity Among these compounds 5-methoxypsoralen (5-MoP) showed the strongest inhibitionwith an IC50 value of 183120583m and with a mixed type ofinhibition [83]

430 Antiaging Effects Rasul and his coworker developeda base and formulation containing 4 concentrated seedextract of F vulgare This formulation shows notable antiag-ing effect with supporting experimental data related to skinmoisture and transepidermal water loss (TEWL) The basewas insignificant while the formulation showed significanteffects on skin moisture and TEWL The texture parameterenergy showed a significant increase proving that the formu-lation possesses potential antiaging effects [50]

431 Bronchodilatory Effect Ethanol extract and essential oilfrom F vulgare exhibited bronchodilatory activity on con-tracted tracheal chains of guinea pig The potassium channelopening effect of fennel may contribute on its relaxant effecton guinea pig tracheal chains [111] Moreover anethole bearsa striking resemblance to the catecholamines epinephrinenorepinephrine and dopamine This structural similarityappears to be responsible for the various sympathomimeticactivities of F vulgare such as bronchodilatory effect [71]

432 Antioxidant Activities Naturally occurring antioxi-dants can be used to protect human beings from oxidativestress damage [112] Fennel was known as excellent source ofnatural antioxidants and contributed to the daily antioxidantdiet [113]Wild fennel was found to exhibit a free radical scav-enging activity with higher content phenolic and flavonoidthan medicinal and edible fennel and the aerial parts ofthe Italian fennel populations showed the highest DPPHscavenging activity [65] Phenolic compounds of fennelincluding caffeoylquinic acid rosmarinic acid eriodictyol-7-orutinoside quercetin-3-O-galactoside and kaempferol-3-O-glucoside showed antioxidant activities [67] The volatileoil showed strong antioxidant activity in comparison withbutyrated hydroxyanisole and butylated hydroxytolueneEthanol and water extracts of fennel showed less antioxidantactivity compared with essential oil [114]

5 Environmental Application

Foeniculum vulgare that is fennel not only exhibited phar-macological activities but also revealed a few environmentalactivities These activities play a key role in the managementof nematode insect mosquitoes and some harmful larvae ofmalaria producing vector Thus the extracts of F vulgare andisolated biologically active compounds have been evaluatedfor their insecticidal repellent acaricidal larvicidal andnematicidal activity [115ndash119] A brief review on the differenttype of ecofriendly environmental activities as reported onthis plant is summarized below

51 Insecticidal Activities The fruit derived phytoconstitu-ents of F vulgare exhibited prominent insecticidal activi-ties against Sitophilus oryzae Callosobruchus chinensis andLasioderma serricorne This activity was examined usingdirect contact application and fumigation methods Thebiologically active constituents that is phenylpropenes (E)-anethole and estragole and the monoterpene (+)-fenchonewere characterized from Foeniculum fruit By using a filter

26 BioMed Research International

paper diffusion test estragole (0168mg cmminus2) caused 91mortality to S oryzae within 1 day after treatment whereas(+)-fenchone and (E)-anethole gave over 90 mortality at 2and 4 day after treatment respectively

After 2 days of treatment all test compounds (0021mg cmminus2 concentration) revealed potent insecticidal activityagainst C chinensis Whereas after 1 day of treatment (E)-anethole (0105mg cmminus2) gave 100mortality of L serricornewhereas 90 and 60 mortality at 4 day after treatment wasachieved with estragole and (+)-fenchone respectively In afumigation test the compounds were much more effectiveagainst adults of S oryzae C chinensis and L serricorne inclosed cups than in open ones indicating that the insecticidalactivity of test compounds was largely attributable to fumi-gant action As naturally occurring insect-control agents theF vulgare fruit-derived materials described could be usefulfor managing field populations of S oryzae C chinensis andL serricorne [116]

52 Acaricidal Activity Fennel oil shows significant acaricid-al activity againstDermatophagoides farinae andDermatoph-agoides pteronyssinus (+)-fenchone and p-anisaldehyde aremajor constituents of fruit oil of F vulgare P-anisaldehydewas the most toxic compound against D farinae and is muchmore effective compared with benzyl benzoate thymol andestragol [118]

53 Repellent Activity The methanolic extract of fruits ofF vulgare was spectroscopically characterized for the pres-ence of biologically active constituents called (+)-fenchoneand (E)-9-octadecenoic acid The repellent activity of theseconstituents was tested against hungry Aedes aegypti femaleswith the help of skin and patch tests and compared withthat of the commercial repellent agent called NN-diethyl-m-toluamide (DEET) and (Z)-9-octadecenoic acid In askin test with female mosquitoes (+)-fenchone and (Z)-9-octadecenoic acid (04mgcm2) exhibitedmoderate repellentactivity at 30min after treatment whereas DEET providedgt1 h of protection against adult mosquitoes at (02mgcm2)Thus (+)-Fenchone and (E)-9-octadecenoic acid are poten-tial mosquito repellent agents or lead compounds [117]

54 Larvicidal Activity Plant extracts and oils may act asalternatives to conventional pesticides for malaria vectorcontrol By considering this aspect Sedaghat et al [119] inves-tigated the larvicidal activity of essential oils of three plantsof Apiaceae family against malaria vector called Anophe-les stephensi The larvicidal activity was evaluated againstlaboratory-reared larvae by standard method of WHO TheF vulgare oil was the most effective against A stephensiwith LC(50) and LC(90) values of 2010 and 4451 ppmrespectively [119] Additionally the essential oil extracts fromleaves flowers and roots of F vulgare exhibit noticeablelarvicidal activity against fourth-instar larvae of themosquitoCulex pipiens molestus Terpineol and 18-cineole content of Fvulgare are the most effective phytoconstituent against Culexpipiens molestus bites offering complete protection for 16 and2 h respectively [120] Recently Zoubiri et al [57] reported

the larvicidal activity of essential oil of fennel seed againstCulex pipiensmosquitoThus F vulgare can serve as a naturallarvicidal agent

55 Nematicidal Activity Oka et al investigated the in vitronematicidal activity of essential oils extracted from 27 spicesand aromatic plants in pot experiments Twelve of thetwenty-seven essential oils immobilized more than 80 ofjuveniles of the root-knot nematodeMeloidogyne javanica ata concentration of 1000 120583Lliter At this concentration mostof these oils also inhibited nematode hatching Essential oilsof Carum carvi Foeniculum vulgare Mentha rotundifoliaand Mentha spicata showed the highest nematicidal activityamong the in vitro tested oils In 3-liter pot experimentsnematicidal activity of the essential oils and their componentswas confirmed at 200 and 150mgkg respectivelyThe resultssuggest that the essential oils and theirmain componentsmayserve as nematicides [115]

6 Toxicity

The long history of ethnomedicinal application with noreports of any serious side effects suggests that F vulgarecould be considered as safe Inmost toxicity experiments car-ried out on F vulgare no sign of toxicity was observed Shahand his coworker in 1991 investigated the detailed toxicityaccount of ethanolic extract of fennel fruit in experimentalmice with respect to acute and 90 days longer term toxicity[121] In experimentation Shah and his coworker observedthe general symptoms of toxicity and mortality for only 24 hin acute toxicity Whereas in another part of toxicity theystudied the effect of fennel extract on mice with 90 dayslong term treatment Acute toxicity of ethanolic extract of Fvulgarewas assessed in 35mice by using three concentrationsnamely 05 1 and 3 gkg body weight In this investigation Fvulgare exhibited no signs of toxicity and no mortality wasobserved upto the dose level 3 gkg body weight In case oflonger term toxicity ethanolic extract of F vulgare (100mgkgbody weightday) was given in drinking water of animals(30 male and 30 female mice) All external morphologicalhaematological and spermatogenic changes in addition tobody and vital organ weights were recorded The extractcaused no significant chronic mortality as compared tocontrols during this investigation The treated male micegained significant weight during chronic treatment while aloss or no significant change in weight was noticed in thefemale mice treated with the same extract The extracts didnot show spermatotoxic effects Thus Shah and his coworkerconcluded that fennel extract is safe based on both acuteandor long term toxicity studies [121] Additionally the plantextract in doses of 05 1 and 3 gkg (orally) did not causeany deaths These doses do not show any type of toxicityagainst several parameters tested namely locomotor activitybizarre reactions sensitivity to sound social interaction tailposture aggressive behaviour ataxia paralysis convulsionstremors prostration exophthalmos pupil size defecationsalivation urination pattern of respiration nasal dischargecyanosis and piloerection Exceptionally only the 3 gkg dose

BioMed Research International 27

showed signs of reduced locomotor activity and piloerec-tion Otherwise all other parameters were negative [108]In another experiment of acute toxicity different solventextracts namely n-hexane methylene chloride ethyl acetateand methanol extracts of F vulgare upto 55 gkg concentra-tion did not revealed any kind of toxicity in mice LD50being 675 110 692 and 15 gkg for n-hexane methylenechloride ethyl acetate and methanol extracts respectively[68] The plant extract of F vulgare was administered orallyat a dose of 100 200 400 600 800 1000 and 2000mgkgof body weight of mice Each group of animals was undervisual observation for 10 days for the external behavior ofneurological toxicity created by plant extract Even the micereceiving highest dose of F vulgare extract did not show anymortality or toxicity demonstrating the safety profile of theplant extract [89]

The acute oral 50 LD50 for anethole in rats was foundto be 2090mgkg Repeated doses of one-third the LD50 ofanethole (695mgkg) given to rat caused mild liver lesionsIt would therefore appear that in normal therapeutic dosagesanethole would have minimal hepatotoxicity When anetholewas fed to rats daily for one year as 025 of the dietno hepatic damage was seen [122] The acute oral LD50 ofessential oil in rats is 1326mgkg [76] The use of F vulgareessential oil as a remedy for control of primary dysmenorrheaincreases concern about its potential teratogenicity due toits estrogen like activity Evaluation of teratogenicity ofessential oil using limb bud mesenchymal cells showed thatthe essential oil may have toxic effect on fetal cells butthere was no evidence of teratogenicity upto concentrationof 93mgmL of culture medium [123] The overall toxicitystudies carried out on F vulgare accounts for its safety at therecommended therapeutic doses

7 Conclusions

The available scientific research on Foeniculum vulgarehas shown that it is an important medicinal plant used ina wide range of ethnomedical treatments especially forabdominal pains antiemetic aperitif arthritis cancer colicin children conjunctivitis constipation depurative diarrheadieresis emmenagogue fever flatulence gastralgia gastritisinsomnia irritable colon kidney ailments as a laxativeleucorrhoea liver pain mouth ulcer and stomachache Thisplant has been in use for a long period of time withoutany documented serious adverse effects Studies carriedout in the past and present indicate that fennel possessesdiverse health benefits and are an important constituentof food Studies have shown that various extracts offennel possess a range of pharmacological actions such asantiaging antiallergic anticolitic antihirsutism anti-inflam-matory antimicrobial and antiviral antimutagenic antino-ciceptive antipyretic antispasmodic antistress antithromb-otic anxiolytic apoptotic cardiovascular chemomodulatoryaction cytoprotection and antitumor cytotoxicity diureticestrogenic properties expectorant galactogenic gastrointes-tinal effect hepatoprotective human liver cytochrome P4503A4 inhibitory hypoglycemic hypolipidemic memory-en-hancing property nootropic and oculohypotensive activity

supporting its traditional use However the most prominentand the well studied effects are the antimicrobial andantioxidant effects of essential oil of fennel in differentexperimental models The observed health benefits may becredited to the presence of the various phytochemicals likevolatile compounds flavonoids phenolic compounds fattyacids and amino acids

Fennel also contains mineral and trace elements likealuminum barium calcium cadmium cobalt chromiumcopper ironmagnesiummanganese nickel lead strontiumand zinc [124] fat soluble vitamins such as vitamins A Eand K water soluble vitamins like ascorbic acid thiamineriboflavin niacin and pyridoxine essential amino acidslike leucine isoleucine phenylalanine and tryptophane maycontribute to the myriad health beneficial effects at least inpart

Most of the pharmacological studies were conductedusing uncharacterized crude extracts of fennel It is difficultto reproduce the results of these studies and pinpoint thebioactive compounds Hence there is a need for chemi-cal standardization and bioactivity-guided identification ofbioactive compounds Among several classes of chemicalconstituents identified in fennel volatile components of fen-nel essential oil and phenolic compounds are assumed to bethe main bioactive compounds responsible for the majorityof its pharmacological effects However the vast traditionaluse and proven pharmacological activities of fennel indicatethat an immense scope still exists for its chemical explorationFuture studies should be focused on validating the mecha-nism of action responsible for the various beneficial effectsand also on understanding which plant based compounds areresponsible for the reported effectsThe required informationwhen available will enhance our knowledge and appreciationfor the use of fennel in our daily diet Also the outcomeof such chemical studies may further expand its existingtherapeutic potential

Thus there are many areas of research related to thisplant that need to be further explored to fully recognize itsbeneficial effects for society Factors such as geographical andseasonal variation play an important role in the authentica-tion of the chemical constituents responsible for the activitywhich also can be an area of interest Thus it is incumbenton researchers to fill the huge gap of insufficient knowledgeand create awareness among pharmacologists as well as inves-tigators towards providing better medicinal value derivedfrom this plant This can be fulfilled only by generatinginterest among the research community through writing ofcritical appraisals (paper) and extending the interdisciplinaryresearch area to focused studies on Foeniculum vulgare

About twenty-one fatty acids were identified and quanti-fied from the abovementioned parts of fennel (Table 3)Theseare caproic acid caprylic acid capric acid undecanoic acidlauric acid myristic acid myristoleic acid pentadecanoicacid palmitic acid heptadecanoic acid stearic acid oleicacid linoleic acid 120572-linolenic acid arachidic acid eicosanoicacid cis-1114-eicosadienoic acid cis-111417-eicosatrienoicacid + heneicosanoic acid behenic acid tricosanoic acidand lignoceric acid Thus Barros and his coworker concludepolyunsaturated fatty acids (PUFA) to be the main groupof fatty acids present in all the fennel parts On the otherhand Vardavas and his coworker reported monounsaturatedfatty acids (MUFA) as the main group of fatty acids infennel [22] Nevertheless unsaturated fatty acids (UFA) rangefrom 66 to 80 and predominate over saturated fatty acids[14] The highest concentration of n-3 fatty acids was foundin fennel leaves while the lowest concentration was found

in inflorescences The ratio of 1205966 to 1205963 fatty acids has animportant role in the human diet The highest levels of n-3fatty acids found in leaves contributed to its lowest ratio of1205966 to 1205963 fatty acids The lowest levels of n-3 fatty acids foundin inflorescences contributed to its highest ratio of 1205966 to 1205963fatty acids

Fennels have smaller amounts of many other nutrientsOn a weight basis fennels contain more calcium (49mg100 g) as compared with apples (714mg100 g) bananas(388mg100 g) dates (250mg100 g) grapes (1086mg100 g) orange (4025mg100 g) prunes (180mg100 g) rais-ins (400mg100 g) and strawberries (1401mg100 g) Phe-nolics are an important constituent of fruit quality becauseof their contribution to the taste colour and nutritionalproperties of fruit Amongst the phenolics analyzed in thefruit of this plant are neochlorogenic acid (140) chloro-genic acid (298) gallic acid (0169) chlorogenic acid(6873) caffeic acid (2960) p-coumaric acid (4325)ferulic acid-7-o-glucoside (5223) quercetin-7-o-glucoside

Thus as a typical seasonal fresh fruit fennels are animportant constituent of the regional diet of Europe and otherregions Different varieties of fennel parts are widely used inmany of the cooking dishes all over world (Table 4) Shootstender leaves and stems are chewed and sucked due to theirexquisite aniseed flavor All these parts are also commonlyused as vegetables They are added raw to salads stewedwith beans and chickpeas used to stuff fish for grilling

and placed in soups and bread bouillons Besides seasoningfennel is used to preserve food Flowering stems sugar andhoneymacerating in brandy produce a highly valorized spiritHerbal teas prepared with fresh tender or dried floweringstems are consumed chilled or hot depending on the seasonF vulgare is famous for its essential oil The characteristicanise odour of F vulgare which is due to its essential oilmakes it an excellent flavoring agent in baked goods meatand fish dishes ice-cream and alcoholic beverages Theculinary uses of fennel are so diversewidespread that it hasbeen exported from country to country for centuries [14]

32 Flavonoids Flavonoids are generally considered as animportant category of antioxidants in the human dietFlavonoids are abundant in the plants of Apiaceae family Ithas been reported that the presence of flavonol glycosidesin fennel species is related to its morphological hetero-geneity and variation Total flavonoid content of hydroal-coholic extracts is about 123 plusmn 018mgg Flavonoids likeeriodictyol-7-rutinoside quercetin-3-rutinoside and ros-marinic acid have been isolated from F vulgare [65]Amongst the flavonoids present in F vulgare the most preva-lent are quercetin-3-glucuronide isoquercitrin quercetin-3-arabinoside kaempferol-3-glucuronide and kaempferol-3-arabinoside and isorhamnetin glucoside [66] Quercetin-3-O-galactoside kaempferol-3-O-rutinoside and kaempferol-3-O-glucoside have also been reported to occur in the aque-ous extract of F vulgare [67] The flavonoids like isorham-netin 3-O-120572-rhamnoside quercetin and kaempferol werealso isolated from the ethyl acetate extract whereas quercetin3-O-rutinoside kaempferol 3-O-rutinoside and quercetin3-O-120573-glucoside were isolated from the methanol extractThese flavonoids exhibit remarkable antinociceptive and anti-inflammatory activity [68] Further quercetin rutin andisoquercitrin were reported to have the immunomodulatoryactivities [69]

33 Phenolic Compounds There has been a growing interestin phenolic components of fruits and vegetables which maypromote human health or lower the risk of disease Aqueous

extract of fennel fruits are rich in phenolic compoundsMany of them have antioxidant activities and hepatopro-tective properties The phenolic compounds present in Fvulgare are considered to be associated with the preventionof diseases possibly induced by oxidative stress such ascardiovascular diseases cancer and inflammation Thesephenolic compounds have received tremendous attentionamong nutritionists food scientists and consumers dueto their role in human health Fennel has been reportedto contain hydroxyl cinnamic acid derivatives flavonoidglycosides and flavonoid aglycones [67] The methanolicextract of fennel seeds contains rosmarinic acid chlorogenicacids as major phenolic compounds (149 and 68 resp)and quercetin and apigenin as themajor flavonoids (171 and125 resp) Also the total phenolic compounds in fennelmethanol extract were higher than the flavonoid compounds[23] F vulgare has been reported to contain phenolic acidslike 3-O-caffeoylquinic acid 4-O-caffeoylquinic acid 5-O-caffeoylquinic acid 13-O-di-caffeoylquinic acid 14-O-di-caffeoylquinic acid and 15-O-di-caffeoylquinic acid [65]Two compounds A and B were isolated and character-ized for the first time from the wild fennel and identi-fied as 34-dihydroxyphenethylalchohol-6-O-caffeoyl-120573-D-glucopyranoside and 3101584081015840-binaringenin respectively Thetotal phenolic and flavonoid contents ofwild fennel (24 and12 resp) were less as compared to cultivated fennel (31and 16 resp) [70]

4 Pharmacological Activities

Foeniculum vulgare is officially noted in Ayurvedic Pharma-copoeia as an important part of polyherbal formulations inthe treatment of different diseases and disorders A numberof biological-pharmacological studies have been undertakento evaluate the indigenous uses of F vulgare Few extracts of Fvulgare and isolated compounds have been evaluated for sev-eral activities namely antiaging antiallergic anticolitic anti-hirsutism anti-inflammatory antimicrobial and antiviralantimutagenic antinociceptive antipyretic antispasmodic

Bacillus subtilis Escherichia coliKlebsiella pneumoniaMicro-coccus luteus Pseudomonas putida Pseudomonas syringaeand Candida albicans According to the results reported byGulfraz et al [92] essential oil of F vulage had significantantimicrobial activities against some of microorganisms ascompared to the methanolic and ethanolic extracts Thediameters of growth inhibition zone ranged from 14 to 31mm(including the diameter of the disc 6mm) with the highestinhibition zone values observed against Bacillus megaterium(31mm) and Bacillus subtilis (29mm) Roby et al [23]investigated antimicrobial effect of the methanol ethanoldiethyl ether and hexane extracts of seed of F vulgare againsttwo species of Gram negative bacteria (Escherichia coli andSalmonella typhi) two species of Gram positive bacteria(Bacillus cereus and Staphylococcus aureus) one species ofyeast (Candida albicans) and one species ofmold (Aspergillusflavus)Themethanolic extract showedmore effective antimi-crobial activity than the other extracts The results fromthe disc diffusion method followed by measurement ofminimum inhibitory concentration (MIC) indicated thatBacillus cereus and Aspergillus flavus were the most sensitivemicroorganisms tested showing the largest inhibition zonesand the lowest MIC values Least activity was exhibitedagainstEscherichia coli with the smallest inhibition zones andthe highest MIC value [23] Shrivastava and Bhargava [93]investigated the antibacterial effect of the crude chloroformand methanol extract of leaves and flowers of F vulgarealong with Raphanus sativus and Brassica nigrum againstEscherichia coli and Staphylococcus aureus Methanol extractof flower of F vulgare showed significant activity againstEscherichia coli whereas crude and chloroform extractsfailed to exhibit antimicrobial activity against Staphylococcusaureus (Table 9) Among different tested bacterial strains the

methanolic fruit extract of F vulgare inhibited the growthof Staphylococcus aureus and Bacillus pumilus with 1127 and1267mm zone of inhibition respectively [7]

Several studies indicating the antifungal effect of Fvulgare along with antibacterial effect are also reported inthe literature Martins et al [94] investigated the antibacterialand antifungal effects of three essential oils of Portugueseplants namely Foeniculum vulgareMentha spicata and Ros-marinus officinalis against Staphylococcus aureus Escherichiacoli Klebsiella pneumonia Pseudomona aeruginosa Staphy-lococcus epidermidis Candida albicans and phytopathogenic

diseases [97] In an in vitro study aqueous and alcoholicseed extracts of F vulgare exhibited inhibitory effect againstAlternaria alternata Mucor rouxii and Aspergillus flavus[98] Interestingly aqueous seed extract of F vulgare showedstrongest antifungal activity as compared to reference fungi-cidal agent that is griseofulvin [99]

All of the above mentioned studies were carried outon the crude extracts and it is difficult to pinpoint theactive antimicrobial metabolite A phenylpropanoid deriva-tive called dillapional characterized from F vulgare stem wasfound to be an antimicrobial constituent with MIC values of125 250 and 125 against Bacillus subtilis Aspergillus nigerand Cladosporium cladosporioides respectively A coumarinderivative scopoletin was also isolated as a marginallyantimicrobial agent [100] The characterization of sevendifferent types of oxygenatedmonoterpenes frommethylene

chloride crude extract of F vulgare [101] suggested thatthe crude extract containing monoterpenes could be a newmedicinal resource for antibacterial agents

A total of 78 compounds were identified from theactive antimycobacterial fraction of F vulgare with thehelp of gas chromatography-mass spectra (GC-MS) Outof these twenty compounds were tested against one sensi-tive and three MDR strains of Mycobacterium tuberculosisusing the Alamar Blue microassay Compounds that showedsome degree of antimycobacterial activity against all strainstested were the following linoleic acid (MIC 100 120583gmL)oleic acid (MIC 100 120583gmL) 13-benzenediol (MIC 100ndash200120583gmL) undecanal (MIC 50ndash200120583gmL) and 24-undecadienal (MIC 25ndash50120583gmL) 24-Undecadienal wasthe most active compound against multidrug resistant Mtuberculosis speciesThus the dietary intake of F vulgaremaylower the risk ofM tuberculosis infection [63]

Orhan et al [5] studied the antiviral activity of theessential oil of fruit sample of F vulgare along with 12other Turkish medicinal plants against the DNA virusHerpessimplex type-1 (HSV-1) and the RNA virus parainfluenzatype-3 (PI-3) Most of the oils and compounds displayedstrong antiviral effects against HSV-1 ranging between 08and 0025 120583gmL However the samples tested were lesseffective against PI-3 with results ranging between 16 and02 120583gmL Only the essential oils of Anethum graveolensFoeniculum vulgare (fully mature) Mentha piperita Menthaspicata Ocimum minutiflorum Ocimum vulgaris and Sat-ureja cuneifolia inhibited this virus significantly

All these literature findings validated the traditional usesof Foeniculum vulgare in infectious disorders like abdomi-nal pains antiemetic arthritis conjunctivitis constipationdepurative diarrhea dieresis fever flatulence gastralgia gas-tritis insomnia irritable colon mouth ulcer stomachacherespiratory disorders skin diseases and so forth There isalways a need for new antimicrobial agents due to rapiddevelopment of resistance Bioactive metabolites of F vulgaremay be a potential source for new antimicrobial agents

42 Anti-Inflammatory Activity Oral administration ofmethanol extract of F vulgare fruit to rat and mice exhibitedinhibitory effects against acute and subacute inflammatorydiseases The anti-inflammatory activity of methanol extractwas evaluated by using three screening protocols namelycarrageenan-induced paw edema arachidonic acid-inducedear edema and formaldehyde-induced arthritis Theseare widely used for testing nonsteroidal anti-inflammatorydrugs For acute inflammationmethanol extract (200mgkg)exhibits significant inhibition of paw edema (69) inducedby carrageenan injection as compared to the control groupof animals Methanol extract of F vulgare also inhibitsear-edema (70) induced by arachidonic acid in mice Thelevel of serum transaminase aspartate aminotransferase(AST) and alanine aminotransferase (ALT) significantlyincreases in the presence of methanolic extract of F vulgareon inflammation induced by formaldehyde as comparedto control group The assessment of the level of AST and

ALT provides a good and simple tool to measure the anti-inflammatory activity of the target compounds [102] Theseoverall results seem to suggest that F vulgare FME mayact on both the cyclooxygenase and lipoxygenase pathways[79]

43 Antiallergic Activity Methanolic extract of F vulgarefruit showed significant inhibitory effect on DNFB- (24-dinitrofluorobenzene-) induced delayed type hypersensitiv-ity after oral administration of 200mgkg once a day for7 days The inhibitory effect on immunologically inducedswelling suggests the possible immunosuppressive propertiesof F vulgare [79]

44 Hepatoprotective Activity Essential oil of F vulgareseeds revealed a potent hepatoprotective effect against acutehepatotoxicity produced by carbon tetrachloride in ratsOral administration of F vulgare essential oil decreases thelevels of serum aspartate aminotransferase (AST) alanineaminotransferase (ALT) alkaline phosphatase (ALP) andbilirubin as compared to the control group Ozbek et alsuggest that the constituents (d-limonene and 120573-myrcene) ofessential oil may have played a key role in the protection ofliver from CCl

4toxicity [9]

45 Anxiolytic Activity Anxiety is the unpleasant feeling offear and concern When anxiety becomes excessive it maybe considered as an anxiety disorder Anxiolytic fennel isa drug used for the treatment of anxiety and its relatedpsychological and physical symptoms Naga Kishore et al[89] investigated the anxiolytic activity of ethanolic extract ofF vulgare fruit with the help of elevated plus maze rota rodopen field test and whole board models The 100 to 200mgdose of extract per kg of body weight of animal revealedsignificant activity when compared to reference anxiolyticdrug called diazepam (1mgkg) Thus fennel extract maypossess anxiolytic activity supporting its traditional claimabout anxiolytic activity reported in 19th edition of Pharma-cology and Pharmacotherapeutics by Sathodkar Bhandarkarand Rege

46 Antistress Activity Drug and food of natural originplay a significant role in public healthcare systems and arebeing investigated as remedies for a number of stress-relateddisorders [103]Thewhole plant extract of F vulgare exhibitednotable antistress effect against stress induced by forcefulswimming of test animals The key parameters that isurinary levels of vanillyl mandelic acid (VMA) and ascorbicacid in rats were used to evaluate antistress activity Theplant extract (50 100 and 200mgkg body weight) showeda significant improvement in urinary levels of VMA (119875 lt0001) and ascorbic acid excretion levels (119875 lt 0001) in testanimals when compared to the normal basal levels in controlgroup of animalsThus the extract of entire plant of F vulgareacts as an antistress agent [13]

47 Memory-Enhancing Property There are a number ofplants whose consumption is believed to enhance memory

22 BioMed Research International

and intelligence These were usually given to children as partof their food F vulgaris an ayurvedic rasayana (mixture)possessing multiple neuropharmacological activities Theantidepressant activity of fennel has been well documentedin ethnomedicine The whole plants extract (50 100 and200mgkg) of F vulgare exhibited memory-enhancing effectagainst scopolamine-induced amnesic rats This experimentwas evaluated by conditioned avoidance response (CAR)technique The CAR of rats administered with the extractincreased gradually to 95 over 7 to 12 days The acquisition(time to achieve 95 CAR) for rats administered with theextract was dose- and time-dependent compared to controlgroup which took 12 days for acquisition The percentavoidance was always higher in the extract-treated groupsas compared to control group Animals receiving 200mgkgbody weight of the extract took ten days while groups treatedwith 100 and 50mgkg doses of the extract required elevenand twelve days respectively to reach the point of acquisitionAdministration of scopolamine produced amnesia as seenfrom reduction in the observed CAR Amnesia was greaterin the control group than in extract-treated groups How-ever continued treatment with F vulgare produced betterretention and recovery in a dose-dependent manner thanthe vehicle-treated animals Recovery from scopolamine-induced amnesia in the extract-treated groups took 3ndash5 dayswhen compared to normal (control) group which took over6 days This overall progress suggests that F vulgare extractpossesses memory-enhancing property [13]

48 Nootropic Activity Alzheimerrsquos disease is a neurode-generative disorder associated with a decline in cognitiveabilities Dementia is one of the age-related mental problemsand a characteristic symptom of Alzheimerrsquos disease Thereis some evidence in favor of use of F vulgare for the treat-ment of cognitive disorders like dementia and Alzheimerrsquosdisease Methanol extract of the whole plant of F vul-gare administered for eight successive days ameliorated theamnesic effect of scopolamine and aging-induced memorydeficits inmiceThis extract increased step-down latency andacetylcholinesterase inhibition in mice significantly Thus Fvulgaremay be employed in treatment of cognitive disorderssuch as dementia and Alzheimerrsquos disease as a nootropic andanticholinesterase agent [80]

49 Antihirsutism Activity Idiopathic hirsutism is definedas the occurrence of excessive male pattern hair growth inwomen who have a normal ovulatory menstrual cycle andnormal levels of serum androgens It may be a disorder ofperipheral androgen metabolism Traditionally Foeniculumvulgare has been used as an estrogenic agent It has beenreputed to increase milk secretion promote menstruationfacilitate birth and increase libido On considering aboveaspect Javidnia and his research team evaluated the antihir-sutism activity of ethanolic extract of F vulgare seed againstidiopathic hirsutism by preparing cream containing 1 and 2of fennel extract The efficacy of treatment with the creamcontaining 2 fennel is better than the cream containing 1fennel and these two were more potent than placebo (control

group) The mean values of hair diameter reduction were78 183 and minus05 for patients receiving the creamscontaining 1 2 and 0 (placebo) respectively [78]

410 Estrogenic Properties Since the discovery of the estrusinducing effects of some plant products in 1926 consider-able effort has been devoted towards the characterizationof phytoestrogens including flavonoids isoflavonoids chal-cones coumestans stilbenes lignans saponins and essentialoils [16] F vulgare has estrogen-like activity In male ratstotal concentration of protein was found to be significantlydecreased in testes and in vasa deferentia whereas increasedin seminal vesicles and in prostate gland On the otherhand simultaneous decrease in the activities of acid andalkaline phosphatase in all these regions (except that alka-line phosphatase was unchanged in vasa) due to the oraladministration of acetone extract of F vulgare fruit wasobserved In female rats oral administration of the extract for10 days led to vaginal cornification and oestrus cycle [8] Totalconcentration of nucleic acids and protein as well as the organweights increased in both the tissues namely mammaryglands and oviducts due to the oral administration of acetoneextract (50 150 and 250120583g100 g body wt) of F vulgare seeds[104] Fennel oil was reported to exhibit estrogenic activitypromote menstruation and alleviate the symptoms of femaleclimacteric and increase libido [71] Administration of fenneloil (25 and 50 120583gmL final concentration in the organ bath)failed to exhibit any remarkable effect in uterine contrac-tion While 10 20 and 40 120583gml concentration of fennel oilrevealed significant inhibitory effect against prostaglandinE2 Fennel oil significantly reduces the frequency of uterinecontraction induced by prostaglandin E2 Thus the extractsof F vulgare have strong estrogenic activity [76]

411 Galactogenic Activity Foeniculum vulgare has been usedformillennia to increasemilk secretion [105]Thus F vulgarebelongs to galactagogue substance Structural similarity ofits main constituent anethole to dopamine seems to beresponsible for galactogenic activityDopamine acts to inhibitthe secretion of the milk-producing hormone prolactinAnethole might influence milk secretion by competing withdopamine at the appropriate receptor sites thereby inhibitingthe antisecretory action of dopamine on prolactin [71] It wasreported that anol (demethylated anethole) causes growthof the lobule-alveolar system in the mammary glands ofimmature female rabbits and induces menstruation in miceand other experimental animals Anol also gave positiveresults in the Jadassohn nipple test a test which involvesthe measurement of changes induced in the nipples ofguinea pigs subjected to the cutaneous application of sexhormones However further research suggests that the actualpharmacologically active agents responsible for galactogenicactivity are polymers of anethole such as dianethole andphotoanethole rather than anol or anethole itself [20 76]

412 Expectorant Activity F vulgare seeds stimulate theciliary motility of the respiratory apparatus and enhance the

BioMed Research International 23

external transport of extraneous corpuscles This action sug-gests a use for fennel in treating bronchial and bronchopul-monary afflictions and in particularly polluted environments[106] The volatile oil of F vulgare stimulates the contractionof the smooth muscles of the trachea an action that couldfacilitate the expectoration of mucus bacteria and othercorpuscles extraneous to the respiratory tracts [74]

413 Anticolitic Activity Essential oil of fennel regulates themotility of smooth muscles of the intestine while at thesame time reducing intestinal gas Alone or combined withother plant medicinals Foeniculum vulgare is indicated in thetreatment of spastic gastrointestinal disturbances in someforms of chronic colitis (which resist other treatments) indyspepsias from gastrointestinal atony in dyspepsias withthe sensation of heaviness in the stomach and so forthTheaddition of fennel to preparations containing anthraquinoniccomponents reduces the occurrence of abdominal pain oftenassociated with this type of laxative [73]

414 Antinociceptive Activity Antinociceptive means anysubstance that inhibits nociception which is a physiologicalprocess underlying the sensation of pain Briefly it reducesthe sensitivity to painful stimuli The various extracts ofaerial part of F vulgare namely hexane methylene chlorideethyl acetate and methanolic extract showed remarkableantinociceptive activity against acetic acid induced writhingin mice [68] The methanolic extract of the aerial parts ofF vulgare exhibited the highest antinociceptive activity at adose level of 2000mgkg while the activity exhibited by theethyl acetate extract was at dose level 800mgkgOn the otherhand n-hexane extract (700mgkg) and methylene chlorideextract (500mgkg) exhibited similar antinociceptive activi-ties being less than peripheral antinociceptive reference drug(acetyl salicylic acid) [68]

415 Diuretic Activity A diuretic is any substance thatpromotes the production of urine Briefly it is an agentthat promotes diuresis Diuretics work by promoting theexpulsion of urine (measured as the urine volume [UV]excreted) and urinary sodium (UNa) from the body and thishelps reduce the volume of blood circulating through thecardiovascular system Caceres et al [107] performed a studyin conscious animals and administered a powdered extractof the whole plant (F vulgare) which had no effect on UVor UNa The ethanolic extract of F vulgare fruit revealedexcellent diuretic activity and proves the earlier folk claimof F vulgare which was reported in the United State ofAmerica (Table 5) The fruit extract showed statistically ahighly significant diuretic effect F vulgare induced diuresis(500mgkg dose)was comparable to that of reference diureticagent urea (960mgkg dose) in mice with a urine outputthat was almost double that of the control group Thediuresis was not associated with changes in sodium andorpotassium excretion [108] In another part of the study theauthors showed that Foeniculum vulgare had little effect onthe noradrenalin contractile responses of aortic rings thus

suggesting that it worked mainly as a diuretic and natriureticwith little effect on arterial vascular tone [77]

416 Cardiovascular Activity An aqueous extract of F vul-gare leaves possesses potential cardiovascular action Thiseffect was investigated using pentobarbital-anaesthetisedmale albino Sprague-Dawley rats [75] An intravenousadministration of the lyophilized boiled water extract ofleaves produced a significant dose-related reduction in arte-rial blood pressure without affecting the heart rate or respi-ratory rate On the other hand the nonboiled aqueous extractshowed very little hypotensive activityThe hypotensive effectof the boiling water extract appeared not to be mediated viaadrenergicmuscarinic ganglionic or serotonergic receptorshowever histamine antagonists inhibited the hypotensiveeffect in a dose-related manner [75]

417 Oculohypotensive Activity The aqueous seed extract ofF vulgare demonstrated significant oculohypotensive activityusing water loading and steroid induced glaucoma modelThis extract exhibited 1749 2116 and 2203 reduction ofintraocular pressure in normotensive rabbits at 03 06and 12 (wv) concentrations respectively A maximummean difference of 3120 was observed between vehiclestreated and extracts treated eyes in water loading experi-mental animal model while a maximum mean intraocularpressure lowering of 3129 was observed in steroid inducedmodel of glaucoma Thus the aqueous extract of F vulgarerevealed oculohypotensive activity which was found to be asgood as that of reference standard antiglaucoma drugs calledtimolol [84]

418 Antithrombotic Activity Tognolini et al [55] providedevidence of potent inhibitory activity of essential oil of F vul-gare against platelet aggregation induced byADP arachidonicacid and collagen in guinea pig plasma Similar findingswere reported by Yoshioka and Tamada [109] for aggregationof rabbit platelets by an aromatic factor of fennel oil Theessential oil and anethole (a constituent of oil) of F vulgaretested in vitro in rat aorta with or without endotheliumdisplayed comparable NO-independent vasorelaxant activityat antiplatelet concentrations It supports the safety of Fvulgare that is free from cytotoxic effects Anethole and Fvulgare did not cause cytotoxicity when incubated for 30minupto 300 120583gmL in platelet viability test This concentrationwas largely compatible with those adopted in the functionalin vitro tests In vivo both F vulgare essential oil andanethole orally administered in a subacute treatment to mice(30mgkgday for 5 days) showed significant antithrom-botic activity preventing the paralysis induced by collagen-epinephrine intravenous injection (70 and 83 protectionresp)Thus essential oil and its main component anethole ofF vulgare showed a safe antithrombotic activity in guinea pigplasma that seems due to their broad spectrum antiplateletactivity clot destabilizing effect and vasorelaxant action [55]

419 Antimutagenic Effect Essential oil of F vulgare revealednoteworthy protective effects against genotoxicity in mice

24 BioMed Research International

induced by cyclophosphamide Genotoxicity and cytotoxicitywere assessed by using mice bone marrow chromosomalaberration micronucleus and sperm abnormality assaysrespectively Oral administration of essential oil (1 and2mLkg) significantly inhibited the frequencies of aberrantmetaphases chromosomal aberrations micronuclei forma-tion and cytotoxicity in mouse bone marrow cells inducedby cyclophosphamide and also produced a significant reduc-tion of abnormal sperm and antagonized the reduction ofcyclophosphamide induced superoxide dismutase catalaseand glutathione activities and inhibited increased malondi-aldehyde content in the liver Additionally F vulgare inhibitsthe oxidative stress induced by cyclophosphamide [90]

420 Gastrointestinal Effect Theaqueous extract of F vulgareshowed remarkable antiulcerogenic effect against ethanol-induced gastric lesions in rats It was found that pretreatmentwith aqueous extract significantly reduced ethanol-inducedgastric damageThis effect of aqueous extract was highest andstatistically significant in 300mgkg group comparedwith thecontrol (119875 lt 0001) group of animal Additionally aqueousextract of F vulgare significantly reduced the whole bloodmalondialdehyde levels while significantly increased nitritenitrate ascorbic acid retinol and beta-carotene levels Thusaqueous extract of F vulgare fruit had clearly a protectiveeffect against ethanol-induced gastric mucosal lesion in rats[81]

421 Chemomodulatory Action The chemopreventive effectof different doses of test diet of Foeniculum vulgare seeds wasexamined against 712-dimethylbenz(a)anthracene- (DMBA-) induced skin papillomagenesis and benzo(a)pyrene-[B(a)P-] induced forestomach papillomagenesis at the peri-initiational level in Swiss albino mice Fennel seeds exhibita significant reduction in the skin and the fore-stomachtumor incidence and tumor multiplicity as compared tothe control group Further biochemical assays showeda significant increase in the contentactivities of phase Ienzymes especially in the case of 6 test diet A concomitantincrease in the activities of the phase II enzymes wasobserved with all the doses of test diet under study Asignificant enhancement in the activities of antioxidantenzymes was observed especially at 4 and 6 test diets offennel These findings were indicative of chemopreventivepotential of fennel against carcinogenesis This is the firstreport showing chemopreventive potential of seeds of fennelagainst carcinogenesis [85]

422 Cytoprotection and Antitumor Activity Anethole is theprincipal active component of fennel seeds which has exhib-ited anticancer activity Al-Harbi et al studied the antitumoractivity of anethole against Ehrlich ascites carcinoma inducedin a tumor model in Swiss albino mice The study revealedthat anethole increased survival time reduced tumor weightand reduced the volume and body weight of the Ehrlichascites tumour-bearing mice It also produced a significantcytotoxic effect in the Ehrlich ascites tumour cells in the pawreduced the levels of nucleic acids and malondialdehyde and

increased glutathione concentrations [110] In vitro cytopro-tection activity of methanolic extract of Foeniculum vulgarewas evaluated against normal human blood lymphocytes bymicronucleus assay and antitumor activity against B16F10melanoma cell line by Trypan blue exclusion assay for cellviability Lymphocyte culture treated with 70 methanolicextract of Foeniculum vulgare showed very less percentage ofmicronucleus that is 0006 as compared to standard drugdoxorubicin which showed 0018 micronucleus On theother hand 70methanolic extract of Foeniculum vulgare haspotent antitumor activity at the concentration of 200120583gmLThe results suggest that the Foeniculum vulgare could beconsidered as a natural resource of antitumor agents as wellas cytoprotective to normal cells [11]

423 Cytotoxicity Kaileh and his coworker investigated thecytotoxic effect of organic extracts of 24 selected Palestinianmedicinal plant species The plant selection was based onexisting ethnobotanic information and interviews with localhealers The extracts of the plants under investigation weretested for their potential antitumor (cytotoxic) effect on themurine fibrosarcoma L929sA cells and on the human breastcancer cells MDA-MB231 and MCF7 The extract from Fvulgare presented an IC (50) value at 24 h of 700 plusmn 28 and500plusmn17 120583gmL on L929sA andMCF7 cells respectivelyThenuclear transcription factor NFkappaB or NF120581B regulatesthe expression of various genes They further investigatedthe effect of nine promising plant extracts withheld fromthe first cell viability screening on NF120581B activation Thedichloromethane and methanol (1 1) extract of aerial part ofF vulgare revealed immunomodulatory NF120581B activities [82]Also Berrington and Lall investigated the in vitro cytotoxicityof acetone extracts of F vulgare and other eight medicinalplants against a noncancerous African green monkey kidney(Vero) cell line and an adenocarcinoma cervical cancer(HeLa) cell line [87]

424 Antipyretic Activity F vulgare extract showedantipyretic activity against hyperpyrexia in mice It wasinduced by SC administration of 2mL100 g of a 20aqueous suspension of brewerrsquos yeast As an antipyreticagent ethanolic extract of F vulgare fruit showed a moderateantipyretic activity that was statistically significant after 30and 90min (119875 lt 001) [108]

425 Hypolipidemic Activity The aqueous extract of F vul-gare revealed notable hypolipidemic and antiatherogenicactivity against Triton WR-1339 induced hyperlipidemiain mice Aqueous extract causes significant reduction ofplasma lipid levels that is cholesterol triglycerides LDL-cholesterol and apolipoprotein-B decreased by 40 2361 and 61 respectively and increase in HDL-cholesteroland apolipoprotein A1 by 85 and 58 respectively [88]

426 Hypoglycemic Activity The essential oil of F vulgareexhibits potential hypoglycemic and antioxidant activityagainst streptozotocin induced diabetes in rats Essentialoil (30mgkg body weight) of F vulgare works in the

correction of hyperglycemia from 1625 plusmn 319mgdL to8197 plusmn 197mgdL with 119875 lt 005 and the activity of serumglutathione peroxidase from 5972 plusmn 278Ug Hb to 9960 plusmn638Ug Hb with 119875 lt 005 Also essential oil of fennelimproves the pathological changes noticed in their kidneyand pancreas as compared with the control group of animalThis can prove its effect as antidiabetic in folk Medicine Thismakes the possibility of its inclusion in antidiabetic drugindustry [12]

427 Antispasmodic Activity The antispasmodic activity of25 and 100mLL of alcoholic extract of Foeniculum vulgarealong with other Germanic medicinal plants namelyMelissaofficinalis Rosmarinus officinalisMentha piperitaMatricariachamomilla Carum carvi and Citrus aurantium were testedemploying the guinea pig ileum and using acetylcholine andhistamine as spasmogens An alcoholic extract of the fruits ofFoeniculum vulgare possesses antispasmodic activity whichinhibits the acetylcholine and histamine-induced guineapig ileal contractions in vitro An essential oil which isobtained from the fruits of Foeniculum vulgare 25 120583gmL and10 120583gmL respectively inhibited oxytocin and prostaglandin[72]

428 Apoptotic Activity The apoptotic activities of ethanolextracts from fruits of seven species of Apiaceae familynamely Eryngium planum Archangelica officinalis Pasti-naca sativa Heracleum sibiricum Carum carvi Foenicu-lum vulgare and Levisticum officinale against ML-1mdashhumanacute myeloblastic leukaemia J-4501mdashhuman acute Tcell leukaemia EOLmdashhuman eosinophilic leukaemia HL-60mdashhuman Caucasian promyelocytic leukaemia 1301mdashhuman T cell leukaemia lymphoblast C-8166mdashhuman Tcell leukaemia U-266B1mdashhuman myeloma WICLmdashhumanCaucasian normal B cell and H-9mdashhuman T cell wereinvestigated with the help of Trypan blue assay and AnnexinV fluos assay [86] The ethanol extract from fruit F vulgareshowed the highest mortality in Trypan blue test for J45cell linemdash4 of viable cells and for C8166 cell linemdash100of mortality However the cells of other lines showed thehighest viability HL60mdash60 EOLmdash48 and MLmdash1ndash42The normal cell line H9 and WICL showed 35 and 25of viable cells respectively C8166 cell line and J-45 cell lineshowed the highest level of the apoptotic cells detected byAnnexin V methodmdash100 and 93 respectively Howeverthe cells of two lines HL60 and EOL-1 showed the lowerlevels of apoptotic cellsmdash52 and 60 respectively Highpercentage of apoptotic cells was observed inH9 andWICLmdash76 and 93 respectively [86]

429 Human Liver Cytochrome P450 3A4 Inhibitory ActivityThirteen compounds isolated from the methanolic extract offennel have been found to possess human liver cytochromeP450 3A4 inhibitory activity Among these compounds 5-methoxypsoralen (5-MoP) showed the strongest inhibitionwith an IC50 value of 183120583m and with a mixed type ofinhibition [83]

430 Antiaging Effects Rasul and his coworker developeda base and formulation containing 4 concentrated seedextract of F vulgare This formulation shows notable antiag-ing effect with supporting experimental data related to skinmoisture and transepidermal water loss (TEWL) The basewas insignificant while the formulation showed significanteffects on skin moisture and TEWL The texture parameterenergy showed a significant increase proving that the formu-lation possesses potential antiaging effects [50]

431 Bronchodilatory Effect Ethanol extract and essential oilfrom F vulgare exhibited bronchodilatory activity on con-tracted tracheal chains of guinea pig The potassium channelopening effect of fennel may contribute on its relaxant effecton guinea pig tracheal chains [111] Moreover anethole bearsa striking resemblance to the catecholamines epinephrinenorepinephrine and dopamine This structural similarityappears to be responsible for the various sympathomimeticactivities of F vulgare such as bronchodilatory effect [71]

432 Antioxidant Activities Naturally occurring antioxi-dants can be used to protect human beings from oxidativestress damage [112] Fennel was known as excellent source ofnatural antioxidants and contributed to the daily antioxidantdiet [113]Wild fennel was found to exhibit a free radical scav-enging activity with higher content phenolic and flavonoidthan medicinal and edible fennel and the aerial parts ofthe Italian fennel populations showed the highest DPPHscavenging activity [65] Phenolic compounds of fennelincluding caffeoylquinic acid rosmarinic acid eriodictyol-7-orutinoside quercetin-3-O-galactoside and kaempferol-3-O-glucoside showed antioxidant activities [67] The volatileoil showed strong antioxidant activity in comparison withbutyrated hydroxyanisole and butylated hydroxytolueneEthanol and water extracts of fennel showed less antioxidantactivity compared with essential oil [114]

5 Environmental Application

Foeniculum vulgare that is fennel not only exhibited phar-macological activities but also revealed a few environmentalactivities These activities play a key role in the managementof nematode insect mosquitoes and some harmful larvae ofmalaria producing vector Thus the extracts of F vulgare andisolated biologically active compounds have been evaluatedfor their insecticidal repellent acaricidal larvicidal andnematicidal activity [115ndash119] A brief review on the differenttype of ecofriendly environmental activities as reported onthis plant is summarized below

51 Insecticidal Activities The fruit derived phytoconstitu-ents of F vulgare exhibited prominent insecticidal activi-ties against Sitophilus oryzae Callosobruchus chinensis andLasioderma serricorne This activity was examined usingdirect contact application and fumigation methods Thebiologically active constituents that is phenylpropenes (E)-anethole and estragole and the monoterpene (+)-fenchonewere characterized from Foeniculum fruit By using a filter

26 BioMed Research International

paper diffusion test estragole (0168mg cmminus2) caused 91mortality to S oryzae within 1 day after treatment whereas(+)-fenchone and (E)-anethole gave over 90 mortality at 2and 4 day after treatment respectively

After 2 days of treatment all test compounds (0021mg cmminus2 concentration) revealed potent insecticidal activityagainst C chinensis Whereas after 1 day of treatment (E)-anethole (0105mg cmminus2) gave 100mortality of L serricornewhereas 90 and 60 mortality at 4 day after treatment wasachieved with estragole and (+)-fenchone respectively In afumigation test the compounds were much more effectiveagainst adults of S oryzae C chinensis and L serricorne inclosed cups than in open ones indicating that the insecticidalactivity of test compounds was largely attributable to fumi-gant action As naturally occurring insect-control agents theF vulgare fruit-derived materials described could be usefulfor managing field populations of S oryzae C chinensis andL serricorne [116]

52 Acaricidal Activity Fennel oil shows significant acaricid-al activity againstDermatophagoides farinae andDermatoph-agoides pteronyssinus (+)-fenchone and p-anisaldehyde aremajor constituents of fruit oil of F vulgare P-anisaldehydewas the most toxic compound against D farinae and is muchmore effective compared with benzyl benzoate thymol andestragol [118]

53 Repellent Activity The methanolic extract of fruits ofF vulgare was spectroscopically characterized for the pres-ence of biologically active constituents called (+)-fenchoneand (E)-9-octadecenoic acid The repellent activity of theseconstituents was tested against hungry Aedes aegypti femaleswith the help of skin and patch tests and compared withthat of the commercial repellent agent called NN-diethyl-m-toluamide (DEET) and (Z)-9-octadecenoic acid In askin test with female mosquitoes (+)-fenchone and (Z)-9-octadecenoic acid (04mgcm2) exhibitedmoderate repellentactivity at 30min after treatment whereas DEET providedgt1 h of protection against adult mosquitoes at (02mgcm2)Thus (+)-Fenchone and (E)-9-octadecenoic acid are poten-tial mosquito repellent agents or lead compounds [117]

54 Larvicidal Activity Plant extracts and oils may act asalternatives to conventional pesticides for malaria vectorcontrol By considering this aspect Sedaghat et al [119] inves-tigated the larvicidal activity of essential oils of three plantsof Apiaceae family against malaria vector called Anophe-les stephensi The larvicidal activity was evaluated againstlaboratory-reared larvae by standard method of WHO TheF vulgare oil was the most effective against A stephensiwith LC(50) and LC(90) values of 2010 and 4451 ppmrespectively [119] Additionally the essential oil extracts fromleaves flowers and roots of F vulgare exhibit noticeablelarvicidal activity against fourth-instar larvae of themosquitoCulex pipiens molestus Terpineol and 18-cineole content of Fvulgare are the most effective phytoconstituent against Culexpipiens molestus bites offering complete protection for 16 and2 h respectively [120] Recently Zoubiri et al [57] reported

the larvicidal activity of essential oil of fennel seed againstCulex pipiensmosquitoThus F vulgare can serve as a naturallarvicidal agent

55 Nematicidal Activity Oka et al investigated the in vitronematicidal activity of essential oils extracted from 27 spicesand aromatic plants in pot experiments Twelve of thetwenty-seven essential oils immobilized more than 80 ofjuveniles of the root-knot nematodeMeloidogyne javanica ata concentration of 1000 120583Lliter At this concentration mostof these oils also inhibited nematode hatching Essential oilsof Carum carvi Foeniculum vulgare Mentha rotundifoliaand Mentha spicata showed the highest nematicidal activityamong the in vitro tested oils In 3-liter pot experimentsnematicidal activity of the essential oils and their componentswas confirmed at 200 and 150mgkg respectivelyThe resultssuggest that the essential oils and theirmain componentsmayserve as nematicides [115]

6 Toxicity

The long history of ethnomedicinal application with noreports of any serious side effects suggests that F vulgarecould be considered as safe Inmost toxicity experiments car-ried out on F vulgare no sign of toxicity was observed Shahand his coworker in 1991 investigated the detailed toxicityaccount of ethanolic extract of fennel fruit in experimentalmice with respect to acute and 90 days longer term toxicity[121] In experimentation Shah and his coworker observedthe general symptoms of toxicity and mortality for only 24 hin acute toxicity Whereas in another part of toxicity theystudied the effect of fennel extract on mice with 90 dayslong term treatment Acute toxicity of ethanolic extract of Fvulgarewas assessed in 35mice by using three concentrationsnamely 05 1 and 3 gkg body weight In this investigation Fvulgare exhibited no signs of toxicity and no mortality wasobserved upto the dose level 3 gkg body weight In case oflonger term toxicity ethanolic extract of F vulgare (100mgkgbody weightday) was given in drinking water of animals(30 male and 30 female mice) All external morphologicalhaematological and spermatogenic changes in addition tobody and vital organ weights were recorded The extractcaused no significant chronic mortality as compared tocontrols during this investigation The treated male micegained significant weight during chronic treatment while aloss or no significant change in weight was noticed in thefemale mice treated with the same extract The extracts didnot show spermatotoxic effects Thus Shah and his coworkerconcluded that fennel extract is safe based on both acuteandor long term toxicity studies [121] Additionally the plantextract in doses of 05 1 and 3 gkg (orally) did not causeany deaths These doses do not show any type of toxicityagainst several parameters tested namely locomotor activitybizarre reactions sensitivity to sound social interaction tailposture aggressive behaviour ataxia paralysis convulsionstremors prostration exophthalmos pupil size defecationsalivation urination pattern of respiration nasal dischargecyanosis and piloerection Exceptionally only the 3 gkg dose

BioMed Research International 27

showed signs of reduced locomotor activity and piloerec-tion Otherwise all other parameters were negative [108]In another experiment of acute toxicity different solventextracts namely n-hexane methylene chloride ethyl acetateand methanol extracts of F vulgare upto 55 gkg concentra-tion did not revealed any kind of toxicity in mice LD50being 675 110 692 and 15 gkg for n-hexane methylenechloride ethyl acetate and methanol extracts respectively[68] The plant extract of F vulgare was administered orallyat a dose of 100 200 400 600 800 1000 and 2000mgkgof body weight of mice Each group of animals was undervisual observation for 10 days for the external behavior ofneurological toxicity created by plant extract Even the micereceiving highest dose of F vulgare extract did not show anymortality or toxicity demonstrating the safety profile of theplant extract [89]

The acute oral 50 LD50 for anethole in rats was foundto be 2090mgkg Repeated doses of one-third the LD50 ofanethole (695mgkg) given to rat caused mild liver lesionsIt would therefore appear that in normal therapeutic dosagesanethole would have minimal hepatotoxicity When anetholewas fed to rats daily for one year as 025 of the dietno hepatic damage was seen [122] The acute oral LD50 ofessential oil in rats is 1326mgkg [76] The use of F vulgareessential oil as a remedy for control of primary dysmenorrheaincreases concern about its potential teratogenicity due toits estrogen like activity Evaluation of teratogenicity ofessential oil using limb bud mesenchymal cells showed thatthe essential oil may have toxic effect on fetal cells butthere was no evidence of teratogenicity upto concentrationof 93mgmL of culture medium [123] The overall toxicitystudies carried out on F vulgare accounts for its safety at therecommended therapeutic doses

7 Conclusions

The available scientific research on Foeniculum vulgarehas shown that it is an important medicinal plant used ina wide range of ethnomedical treatments especially forabdominal pains antiemetic aperitif arthritis cancer colicin children conjunctivitis constipation depurative diarrheadieresis emmenagogue fever flatulence gastralgia gastritisinsomnia irritable colon kidney ailments as a laxativeleucorrhoea liver pain mouth ulcer and stomachache Thisplant has been in use for a long period of time withoutany documented serious adverse effects Studies carriedout in the past and present indicate that fennel possessesdiverse health benefits and are an important constituentof food Studies have shown that various extracts offennel possess a range of pharmacological actions such asantiaging antiallergic anticolitic antihirsutism anti-inflam-matory antimicrobial and antiviral antimutagenic antino-ciceptive antipyretic antispasmodic antistress antithromb-otic anxiolytic apoptotic cardiovascular chemomodulatoryaction cytoprotection and antitumor cytotoxicity diureticestrogenic properties expectorant galactogenic gastrointes-tinal effect hepatoprotective human liver cytochrome P4503A4 inhibitory hypoglycemic hypolipidemic memory-en-hancing property nootropic and oculohypotensive activity

supporting its traditional use However the most prominentand the well studied effects are the antimicrobial andantioxidant effects of essential oil of fennel in differentexperimental models The observed health benefits may becredited to the presence of the various phytochemicals likevolatile compounds flavonoids phenolic compounds fattyacids and amino acids

Fennel also contains mineral and trace elements likealuminum barium calcium cadmium cobalt chromiumcopper ironmagnesiummanganese nickel lead strontiumand zinc [124] fat soluble vitamins such as vitamins A Eand K water soluble vitamins like ascorbic acid thiamineriboflavin niacin and pyridoxine essential amino acidslike leucine isoleucine phenylalanine and tryptophane maycontribute to the myriad health beneficial effects at least inpart

Most of the pharmacological studies were conductedusing uncharacterized crude extracts of fennel It is difficultto reproduce the results of these studies and pinpoint thebioactive compounds Hence there is a need for chemi-cal standardization and bioactivity-guided identification ofbioactive compounds Among several classes of chemicalconstituents identified in fennel volatile components of fen-nel essential oil and phenolic compounds are assumed to bethe main bioactive compounds responsible for the majorityof its pharmacological effects However the vast traditionaluse and proven pharmacological activities of fennel indicatethat an immense scope still exists for its chemical explorationFuture studies should be focused on validating the mecha-nism of action responsible for the various beneficial effectsand also on understanding which plant based compounds areresponsible for the reported effectsThe required informationwhen available will enhance our knowledge and appreciationfor the use of fennel in our daily diet Also the outcomeof such chemical studies may further expand its existingtherapeutic potential

Thus there are many areas of research related to thisplant that need to be further explored to fully recognize itsbeneficial effects for society Factors such as geographical andseasonal variation play an important role in the authentica-tion of the chemical constituents responsible for the activitywhich also can be an area of interest Thus it is incumbenton researchers to fill the huge gap of insufficient knowledgeand create awareness among pharmacologists as well as inves-tigators towards providing better medicinal value derivedfrom this plant This can be fulfilled only by generatinginterest among the research community through writing ofcritical appraisals (paper) and extending the interdisciplinaryresearch area to focused studies on Foeniculum vulgare

32 Flavonoids Flavonoids are generally considered as animportant category of antioxidants in the human dietFlavonoids are abundant in the plants of Apiaceae family Ithas been reported that the presence of flavonol glycosidesin fennel species is related to its morphological hetero-geneity and variation Total flavonoid content of hydroal-coholic extracts is about 123 plusmn 018mgg Flavonoids likeeriodictyol-7-rutinoside quercetin-3-rutinoside and ros-marinic acid have been isolated from F vulgare [65]Amongst the flavonoids present in F vulgare the most preva-lent are quercetin-3-glucuronide isoquercitrin quercetin-3-arabinoside kaempferol-3-glucuronide and kaempferol-3-arabinoside and isorhamnetin glucoside [66] Quercetin-3-O-galactoside kaempferol-3-O-rutinoside and kaempferol-3-O-glucoside have also been reported to occur in the aque-ous extract of F vulgare [67] The flavonoids like isorham-netin 3-O-120572-rhamnoside quercetin and kaempferol werealso isolated from the ethyl acetate extract whereas quercetin3-O-rutinoside kaempferol 3-O-rutinoside and quercetin3-O-120573-glucoside were isolated from the methanol extractThese flavonoids exhibit remarkable antinociceptive and anti-inflammatory activity [68] Further quercetin rutin andisoquercitrin were reported to have the immunomodulatoryactivities [69]

33 Phenolic Compounds There has been a growing interestin phenolic components of fruits and vegetables which maypromote human health or lower the risk of disease Aqueous

extract of fennel fruits are rich in phenolic compoundsMany of them have antioxidant activities and hepatopro-tective properties The phenolic compounds present in Fvulgare are considered to be associated with the preventionof diseases possibly induced by oxidative stress such ascardiovascular diseases cancer and inflammation Thesephenolic compounds have received tremendous attentionamong nutritionists food scientists and consumers dueto their role in human health Fennel has been reportedto contain hydroxyl cinnamic acid derivatives flavonoidglycosides and flavonoid aglycones [67] The methanolicextract of fennel seeds contains rosmarinic acid chlorogenicacids as major phenolic compounds (149 and 68 resp)and quercetin and apigenin as themajor flavonoids (171 and125 resp) Also the total phenolic compounds in fennelmethanol extract were higher than the flavonoid compounds[23] F vulgare has been reported to contain phenolic acidslike 3-O-caffeoylquinic acid 4-O-caffeoylquinic acid 5-O-caffeoylquinic acid 13-O-di-caffeoylquinic acid 14-O-di-caffeoylquinic acid and 15-O-di-caffeoylquinic acid [65]Two compounds A and B were isolated and character-ized for the first time from the wild fennel and identi-fied as 34-dihydroxyphenethylalchohol-6-O-caffeoyl-120573-D-glucopyranoside and 3101584081015840-binaringenin respectively Thetotal phenolic and flavonoid contents ofwild fennel (24 and12 resp) were less as compared to cultivated fennel (31and 16 resp) [70]

4 Pharmacological Activities

Foeniculum vulgare is officially noted in Ayurvedic Pharma-copoeia as an important part of polyherbal formulations inthe treatment of different diseases and disorders A numberof biological-pharmacological studies have been undertakento evaluate the indigenous uses of F vulgare Few extracts of Fvulgare and isolated compounds have been evaluated for sev-eral activities namely antiaging antiallergic anticolitic anti-hirsutism anti-inflammatory antimicrobial and antiviralantimutagenic antinociceptive antipyretic antispasmodic

Bacillus subtilis Escherichia coliKlebsiella pneumoniaMicro-coccus luteus Pseudomonas putida Pseudomonas syringaeand Candida albicans According to the results reported byGulfraz et al [92] essential oil of F vulage had significantantimicrobial activities against some of microorganisms ascompared to the methanolic and ethanolic extracts Thediameters of growth inhibition zone ranged from 14 to 31mm(including the diameter of the disc 6mm) with the highestinhibition zone values observed against Bacillus megaterium(31mm) and Bacillus subtilis (29mm) Roby et al [23]investigated antimicrobial effect of the methanol ethanoldiethyl ether and hexane extracts of seed of F vulgare againsttwo species of Gram negative bacteria (Escherichia coli andSalmonella typhi) two species of Gram positive bacteria(Bacillus cereus and Staphylococcus aureus) one species ofyeast (Candida albicans) and one species ofmold (Aspergillusflavus)Themethanolic extract showedmore effective antimi-crobial activity than the other extracts The results fromthe disc diffusion method followed by measurement ofminimum inhibitory concentration (MIC) indicated thatBacillus cereus and Aspergillus flavus were the most sensitivemicroorganisms tested showing the largest inhibition zonesand the lowest MIC values Least activity was exhibitedagainstEscherichia coli with the smallest inhibition zones andthe highest MIC value [23] Shrivastava and Bhargava [93]investigated the antibacterial effect of the crude chloroformand methanol extract of leaves and flowers of F vulgarealong with Raphanus sativus and Brassica nigrum againstEscherichia coli and Staphylococcus aureus Methanol extractof flower of F vulgare showed significant activity againstEscherichia coli whereas crude and chloroform extractsfailed to exhibit antimicrobial activity against Staphylococcusaureus (Table 9) Among different tested bacterial strains the

methanolic fruit extract of F vulgare inhibited the growthof Staphylococcus aureus and Bacillus pumilus with 1127 and1267mm zone of inhibition respectively [7]

Several studies indicating the antifungal effect of Fvulgare along with antibacterial effect are also reported inthe literature Martins et al [94] investigated the antibacterialand antifungal effects of three essential oils of Portugueseplants namely Foeniculum vulgareMentha spicata and Ros-marinus officinalis against Staphylococcus aureus Escherichiacoli Klebsiella pneumonia Pseudomona aeruginosa Staphy-lococcus epidermidis Candida albicans and phytopathogenic

diseases [97] In an in vitro study aqueous and alcoholicseed extracts of F vulgare exhibited inhibitory effect againstAlternaria alternata Mucor rouxii and Aspergillus flavus[98] Interestingly aqueous seed extract of F vulgare showedstrongest antifungal activity as compared to reference fungi-cidal agent that is griseofulvin [99]

All of the above mentioned studies were carried outon the crude extracts and it is difficult to pinpoint theactive antimicrobial metabolite A phenylpropanoid deriva-tive called dillapional characterized from F vulgare stem wasfound to be an antimicrobial constituent with MIC values of125 250 and 125 against Bacillus subtilis Aspergillus nigerand Cladosporium cladosporioides respectively A coumarinderivative scopoletin was also isolated as a marginallyantimicrobial agent [100] The characterization of sevendifferent types of oxygenatedmonoterpenes frommethylene

chloride crude extract of F vulgare [101] suggested thatthe crude extract containing monoterpenes could be a newmedicinal resource for antibacterial agents

A total of 78 compounds were identified from theactive antimycobacterial fraction of F vulgare with thehelp of gas chromatography-mass spectra (GC-MS) Outof these twenty compounds were tested against one sensi-tive and three MDR strains of Mycobacterium tuberculosisusing the Alamar Blue microassay Compounds that showedsome degree of antimycobacterial activity against all strainstested were the following linoleic acid (MIC 100 120583gmL)oleic acid (MIC 100 120583gmL) 13-benzenediol (MIC 100ndash200120583gmL) undecanal (MIC 50ndash200120583gmL) and 24-undecadienal (MIC 25ndash50120583gmL) 24-Undecadienal wasthe most active compound against multidrug resistant Mtuberculosis speciesThus the dietary intake of F vulgaremaylower the risk ofM tuberculosis infection [63]

Orhan et al [5] studied the antiviral activity of theessential oil of fruit sample of F vulgare along with 12other Turkish medicinal plants against the DNA virusHerpessimplex type-1 (HSV-1) and the RNA virus parainfluenzatype-3 (PI-3) Most of the oils and compounds displayedstrong antiviral effects against HSV-1 ranging between 08and 0025 120583gmL However the samples tested were lesseffective against PI-3 with results ranging between 16 and02 120583gmL Only the essential oils of Anethum graveolensFoeniculum vulgare (fully mature) Mentha piperita Menthaspicata Ocimum minutiflorum Ocimum vulgaris and Sat-ureja cuneifolia inhibited this virus significantly

All these literature findings validated the traditional usesof Foeniculum vulgare in infectious disorders like abdomi-nal pains antiemetic arthritis conjunctivitis constipationdepurative diarrhea dieresis fever flatulence gastralgia gas-tritis insomnia irritable colon mouth ulcer stomachacherespiratory disorders skin diseases and so forth There isalways a need for new antimicrobial agents due to rapiddevelopment of resistance Bioactive metabolites of F vulgaremay be a potential source for new antimicrobial agents

42 Anti-Inflammatory Activity Oral administration ofmethanol extract of F vulgare fruit to rat and mice exhibitedinhibitory effects against acute and subacute inflammatorydiseases The anti-inflammatory activity of methanol extractwas evaluated by using three screening protocols namelycarrageenan-induced paw edema arachidonic acid-inducedear edema and formaldehyde-induced arthritis Theseare widely used for testing nonsteroidal anti-inflammatorydrugs For acute inflammationmethanol extract (200mgkg)exhibits significant inhibition of paw edema (69) inducedby carrageenan injection as compared to the control groupof animals Methanol extract of F vulgare also inhibitsear-edema (70) induced by arachidonic acid in mice Thelevel of serum transaminase aspartate aminotransferase(AST) and alanine aminotransferase (ALT) significantlyincreases in the presence of methanolic extract of F vulgareon inflammation induced by formaldehyde as comparedto control group The assessment of the level of AST and

ALT provides a good and simple tool to measure the anti-inflammatory activity of the target compounds [102] Theseoverall results seem to suggest that F vulgare FME mayact on both the cyclooxygenase and lipoxygenase pathways[79]

43 Antiallergic Activity Methanolic extract of F vulgarefruit showed significant inhibitory effect on DNFB- (24-dinitrofluorobenzene-) induced delayed type hypersensitiv-ity after oral administration of 200mgkg once a day for7 days The inhibitory effect on immunologically inducedswelling suggests the possible immunosuppressive propertiesof F vulgare [79]

44 Hepatoprotective Activity Essential oil of F vulgareseeds revealed a potent hepatoprotective effect against acutehepatotoxicity produced by carbon tetrachloride in ratsOral administration of F vulgare essential oil decreases thelevels of serum aspartate aminotransferase (AST) alanineaminotransferase (ALT) alkaline phosphatase (ALP) andbilirubin as compared to the control group Ozbek et alsuggest that the constituents (d-limonene and 120573-myrcene) ofessential oil may have played a key role in the protection ofliver from CCl

4toxicity [9]

45 Anxiolytic Activity Anxiety is the unpleasant feeling offear and concern When anxiety becomes excessive it maybe considered as an anxiety disorder Anxiolytic fennel isa drug used for the treatment of anxiety and its relatedpsychological and physical symptoms Naga Kishore et al[89] investigated the anxiolytic activity of ethanolic extract ofF vulgare fruit with the help of elevated plus maze rota rodopen field test and whole board models The 100 to 200mgdose of extract per kg of body weight of animal revealedsignificant activity when compared to reference anxiolyticdrug called diazepam (1mgkg) Thus fennel extract maypossess anxiolytic activity supporting its traditional claimabout anxiolytic activity reported in 19th edition of Pharma-cology and Pharmacotherapeutics by Sathodkar Bhandarkarand Rege

46 Antistress Activity Drug and food of natural originplay a significant role in public healthcare systems and arebeing investigated as remedies for a number of stress-relateddisorders [103]Thewhole plant extract of F vulgare exhibitednotable antistress effect against stress induced by forcefulswimming of test animals The key parameters that isurinary levels of vanillyl mandelic acid (VMA) and ascorbicacid in rats were used to evaluate antistress activity Theplant extract (50 100 and 200mgkg body weight) showeda significant improvement in urinary levels of VMA (119875 lt0001) and ascorbic acid excretion levels (119875 lt 0001) in testanimals when compared to the normal basal levels in controlgroup of animalsThus the extract of entire plant of F vulgareacts as an antistress agent [13]

47 Memory-Enhancing Property There are a number ofplants whose consumption is believed to enhance memory

22 BioMed Research International

and intelligence These were usually given to children as partof their food F vulgaris an ayurvedic rasayana (mixture)possessing multiple neuropharmacological activities Theantidepressant activity of fennel has been well documentedin ethnomedicine The whole plants extract (50 100 and200mgkg) of F vulgare exhibited memory-enhancing effectagainst scopolamine-induced amnesic rats This experimentwas evaluated by conditioned avoidance response (CAR)technique The CAR of rats administered with the extractincreased gradually to 95 over 7 to 12 days The acquisition(time to achieve 95 CAR) for rats administered with theextract was dose- and time-dependent compared to controlgroup which took 12 days for acquisition The percentavoidance was always higher in the extract-treated groupsas compared to control group Animals receiving 200mgkgbody weight of the extract took ten days while groups treatedwith 100 and 50mgkg doses of the extract required elevenand twelve days respectively to reach the point of acquisitionAdministration of scopolamine produced amnesia as seenfrom reduction in the observed CAR Amnesia was greaterin the control group than in extract-treated groups How-ever continued treatment with F vulgare produced betterretention and recovery in a dose-dependent manner thanthe vehicle-treated animals Recovery from scopolamine-induced amnesia in the extract-treated groups took 3ndash5 dayswhen compared to normal (control) group which took over6 days This overall progress suggests that F vulgare extractpossesses memory-enhancing property [13]

48 Nootropic Activity Alzheimerrsquos disease is a neurode-generative disorder associated with a decline in cognitiveabilities Dementia is one of the age-related mental problemsand a characteristic symptom of Alzheimerrsquos disease Thereis some evidence in favor of use of F vulgare for the treat-ment of cognitive disorders like dementia and Alzheimerrsquosdisease Methanol extract of the whole plant of F vul-gare administered for eight successive days ameliorated theamnesic effect of scopolamine and aging-induced memorydeficits inmiceThis extract increased step-down latency andacetylcholinesterase inhibition in mice significantly Thus Fvulgaremay be employed in treatment of cognitive disorderssuch as dementia and Alzheimerrsquos disease as a nootropic andanticholinesterase agent [80]

49 Antihirsutism Activity Idiopathic hirsutism is definedas the occurrence of excessive male pattern hair growth inwomen who have a normal ovulatory menstrual cycle andnormal levels of serum androgens It may be a disorder ofperipheral androgen metabolism Traditionally Foeniculumvulgare has been used as an estrogenic agent It has beenreputed to increase milk secretion promote menstruationfacilitate birth and increase libido On considering aboveaspect Javidnia and his research team evaluated the antihir-sutism activity of ethanolic extract of F vulgare seed againstidiopathic hirsutism by preparing cream containing 1 and 2of fennel extract The efficacy of treatment with the creamcontaining 2 fennel is better than the cream containing 1fennel and these two were more potent than placebo (control

group) The mean values of hair diameter reduction were78 183 and minus05 for patients receiving the creamscontaining 1 2 and 0 (placebo) respectively [78]

410 Estrogenic Properties Since the discovery of the estrusinducing effects of some plant products in 1926 consider-able effort has been devoted towards the characterizationof phytoestrogens including flavonoids isoflavonoids chal-cones coumestans stilbenes lignans saponins and essentialoils [16] F vulgare has estrogen-like activity In male ratstotal concentration of protein was found to be significantlydecreased in testes and in vasa deferentia whereas increasedin seminal vesicles and in prostate gland On the otherhand simultaneous decrease in the activities of acid andalkaline phosphatase in all these regions (except that alka-line phosphatase was unchanged in vasa) due to the oraladministration of acetone extract of F vulgare fruit wasobserved In female rats oral administration of the extract for10 days led to vaginal cornification and oestrus cycle [8] Totalconcentration of nucleic acids and protein as well as the organweights increased in both the tissues namely mammaryglands and oviducts due to the oral administration of acetoneextract (50 150 and 250120583g100 g body wt) of F vulgare seeds[104] Fennel oil was reported to exhibit estrogenic activitypromote menstruation and alleviate the symptoms of femaleclimacteric and increase libido [71] Administration of fenneloil (25 and 50 120583gmL final concentration in the organ bath)failed to exhibit any remarkable effect in uterine contrac-tion While 10 20 and 40 120583gml concentration of fennel oilrevealed significant inhibitory effect against prostaglandinE2 Fennel oil significantly reduces the frequency of uterinecontraction induced by prostaglandin E2 Thus the extractsof F vulgare have strong estrogenic activity [76]

411 Galactogenic Activity Foeniculum vulgare has been usedformillennia to increasemilk secretion [105]Thus F vulgarebelongs to galactagogue substance Structural similarity ofits main constituent anethole to dopamine seems to beresponsible for galactogenic activityDopamine acts to inhibitthe secretion of the milk-producing hormone prolactinAnethole might influence milk secretion by competing withdopamine at the appropriate receptor sites thereby inhibitingthe antisecretory action of dopamine on prolactin [71] It wasreported that anol (demethylated anethole) causes growthof the lobule-alveolar system in the mammary glands ofimmature female rabbits and induces menstruation in miceand other experimental animals Anol also gave positiveresults in the Jadassohn nipple test a test which involvesthe measurement of changes induced in the nipples ofguinea pigs subjected to the cutaneous application of sexhormones However further research suggests that the actualpharmacologically active agents responsible for galactogenicactivity are polymers of anethole such as dianethole andphotoanethole rather than anol or anethole itself [20 76]

412 Expectorant Activity F vulgare seeds stimulate theciliary motility of the respiratory apparatus and enhance the

BioMed Research International 23

external transport of extraneous corpuscles This action sug-gests a use for fennel in treating bronchial and bronchopul-monary afflictions and in particularly polluted environments[106] The volatile oil of F vulgare stimulates the contractionof the smooth muscles of the trachea an action that couldfacilitate the expectoration of mucus bacteria and othercorpuscles extraneous to the respiratory tracts [74]

413 Anticolitic Activity Essential oil of fennel regulates themotility of smooth muscles of the intestine while at thesame time reducing intestinal gas Alone or combined withother plant medicinals Foeniculum vulgare is indicated in thetreatment of spastic gastrointestinal disturbances in someforms of chronic colitis (which resist other treatments) indyspepsias from gastrointestinal atony in dyspepsias withthe sensation of heaviness in the stomach and so forthTheaddition of fennel to preparations containing anthraquinoniccomponents reduces the occurrence of abdominal pain oftenassociated with this type of laxative [73]

414 Antinociceptive Activity Antinociceptive means anysubstance that inhibits nociception which is a physiologicalprocess underlying the sensation of pain Briefly it reducesthe sensitivity to painful stimuli The various extracts ofaerial part of F vulgare namely hexane methylene chlorideethyl acetate and methanolic extract showed remarkableantinociceptive activity against acetic acid induced writhingin mice [68] The methanolic extract of the aerial parts ofF vulgare exhibited the highest antinociceptive activity at adose level of 2000mgkg while the activity exhibited by theethyl acetate extract was at dose level 800mgkgOn the otherhand n-hexane extract (700mgkg) and methylene chlorideextract (500mgkg) exhibited similar antinociceptive activi-ties being less than peripheral antinociceptive reference drug(acetyl salicylic acid) [68]

415 Diuretic Activity A diuretic is any substance thatpromotes the production of urine Briefly it is an agentthat promotes diuresis Diuretics work by promoting theexpulsion of urine (measured as the urine volume [UV]excreted) and urinary sodium (UNa) from the body and thishelps reduce the volume of blood circulating through thecardiovascular system Caceres et al [107] performed a studyin conscious animals and administered a powdered extractof the whole plant (F vulgare) which had no effect on UVor UNa The ethanolic extract of F vulgare fruit revealedexcellent diuretic activity and proves the earlier folk claimof F vulgare which was reported in the United State ofAmerica (Table 5) The fruit extract showed statistically ahighly significant diuretic effect F vulgare induced diuresis(500mgkg dose)was comparable to that of reference diureticagent urea (960mgkg dose) in mice with a urine outputthat was almost double that of the control group Thediuresis was not associated with changes in sodium andorpotassium excretion [108] In another part of the study theauthors showed that Foeniculum vulgare had little effect onthe noradrenalin contractile responses of aortic rings thus

suggesting that it worked mainly as a diuretic and natriureticwith little effect on arterial vascular tone [77]

416 Cardiovascular Activity An aqueous extract of F vul-gare leaves possesses potential cardiovascular action Thiseffect was investigated using pentobarbital-anaesthetisedmale albino Sprague-Dawley rats [75] An intravenousadministration of the lyophilized boiled water extract ofleaves produced a significant dose-related reduction in arte-rial blood pressure without affecting the heart rate or respi-ratory rate On the other hand the nonboiled aqueous extractshowed very little hypotensive activityThe hypotensive effectof the boiling water extract appeared not to be mediated viaadrenergicmuscarinic ganglionic or serotonergic receptorshowever histamine antagonists inhibited the hypotensiveeffect in a dose-related manner [75]

417 Oculohypotensive Activity The aqueous seed extract ofF vulgare demonstrated significant oculohypotensive activityusing water loading and steroid induced glaucoma modelThis extract exhibited 1749 2116 and 2203 reduction ofintraocular pressure in normotensive rabbits at 03 06and 12 (wv) concentrations respectively A maximummean difference of 3120 was observed between vehiclestreated and extracts treated eyes in water loading experi-mental animal model while a maximum mean intraocularpressure lowering of 3129 was observed in steroid inducedmodel of glaucoma Thus the aqueous extract of F vulgarerevealed oculohypotensive activity which was found to be asgood as that of reference standard antiglaucoma drugs calledtimolol [84]

418 Antithrombotic Activity Tognolini et al [55] providedevidence of potent inhibitory activity of essential oil of F vul-gare against platelet aggregation induced byADP arachidonicacid and collagen in guinea pig plasma Similar findingswere reported by Yoshioka and Tamada [109] for aggregationof rabbit platelets by an aromatic factor of fennel oil Theessential oil and anethole (a constituent of oil) of F vulgaretested in vitro in rat aorta with or without endotheliumdisplayed comparable NO-independent vasorelaxant activityat antiplatelet concentrations It supports the safety of Fvulgare that is free from cytotoxic effects Anethole and Fvulgare did not cause cytotoxicity when incubated for 30minupto 300 120583gmL in platelet viability test This concentrationwas largely compatible with those adopted in the functionalin vitro tests In vivo both F vulgare essential oil andanethole orally administered in a subacute treatment to mice(30mgkgday for 5 days) showed significant antithrom-botic activity preventing the paralysis induced by collagen-epinephrine intravenous injection (70 and 83 protectionresp)Thus essential oil and its main component anethole ofF vulgare showed a safe antithrombotic activity in guinea pigplasma that seems due to their broad spectrum antiplateletactivity clot destabilizing effect and vasorelaxant action [55]

419 Antimutagenic Effect Essential oil of F vulgare revealednoteworthy protective effects against genotoxicity in mice

24 BioMed Research International

induced by cyclophosphamide Genotoxicity and cytotoxicitywere assessed by using mice bone marrow chromosomalaberration micronucleus and sperm abnormality assaysrespectively Oral administration of essential oil (1 and2mLkg) significantly inhibited the frequencies of aberrantmetaphases chromosomal aberrations micronuclei forma-tion and cytotoxicity in mouse bone marrow cells inducedby cyclophosphamide and also produced a significant reduc-tion of abnormal sperm and antagonized the reduction ofcyclophosphamide induced superoxide dismutase catalaseand glutathione activities and inhibited increased malondi-aldehyde content in the liver Additionally F vulgare inhibitsthe oxidative stress induced by cyclophosphamide [90]

420 Gastrointestinal Effect Theaqueous extract of F vulgareshowed remarkable antiulcerogenic effect against ethanol-induced gastric lesions in rats It was found that pretreatmentwith aqueous extract significantly reduced ethanol-inducedgastric damageThis effect of aqueous extract was highest andstatistically significant in 300mgkg group comparedwith thecontrol (119875 lt 0001) group of animal Additionally aqueousextract of F vulgare significantly reduced the whole bloodmalondialdehyde levels while significantly increased nitritenitrate ascorbic acid retinol and beta-carotene levels Thusaqueous extract of F vulgare fruit had clearly a protectiveeffect against ethanol-induced gastric mucosal lesion in rats[81]

421 Chemomodulatory Action The chemopreventive effectof different doses of test diet of Foeniculum vulgare seeds wasexamined against 712-dimethylbenz(a)anthracene- (DMBA-) induced skin papillomagenesis and benzo(a)pyrene-[B(a)P-] induced forestomach papillomagenesis at the peri-initiational level in Swiss albino mice Fennel seeds exhibita significant reduction in the skin and the fore-stomachtumor incidence and tumor multiplicity as compared tothe control group Further biochemical assays showeda significant increase in the contentactivities of phase Ienzymes especially in the case of 6 test diet A concomitantincrease in the activities of the phase II enzymes wasobserved with all the doses of test diet under study Asignificant enhancement in the activities of antioxidantenzymes was observed especially at 4 and 6 test diets offennel These findings were indicative of chemopreventivepotential of fennel against carcinogenesis This is the firstreport showing chemopreventive potential of seeds of fennelagainst carcinogenesis [85]

422 Cytoprotection and Antitumor Activity Anethole is theprincipal active component of fennel seeds which has exhib-ited anticancer activity Al-Harbi et al studied the antitumoractivity of anethole against Ehrlich ascites carcinoma inducedin a tumor model in Swiss albino mice The study revealedthat anethole increased survival time reduced tumor weightand reduced the volume and body weight of the Ehrlichascites tumour-bearing mice It also produced a significantcytotoxic effect in the Ehrlich ascites tumour cells in the pawreduced the levels of nucleic acids and malondialdehyde and

increased glutathione concentrations [110] In vitro cytopro-tection activity of methanolic extract of Foeniculum vulgarewas evaluated against normal human blood lymphocytes bymicronucleus assay and antitumor activity against B16F10melanoma cell line by Trypan blue exclusion assay for cellviability Lymphocyte culture treated with 70 methanolicextract of Foeniculum vulgare showed very less percentage ofmicronucleus that is 0006 as compared to standard drugdoxorubicin which showed 0018 micronucleus On theother hand 70methanolic extract of Foeniculum vulgare haspotent antitumor activity at the concentration of 200120583gmLThe results suggest that the Foeniculum vulgare could beconsidered as a natural resource of antitumor agents as wellas cytoprotective to normal cells [11]

423 Cytotoxicity Kaileh and his coworker investigated thecytotoxic effect of organic extracts of 24 selected Palestinianmedicinal plant species The plant selection was based onexisting ethnobotanic information and interviews with localhealers The extracts of the plants under investigation weretested for their potential antitumor (cytotoxic) effect on themurine fibrosarcoma L929sA cells and on the human breastcancer cells MDA-MB231 and MCF7 The extract from Fvulgare presented an IC (50) value at 24 h of 700 plusmn 28 and500plusmn17 120583gmL on L929sA andMCF7 cells respectivelyThenuclear transcription factor NFkappaB or NF120581B regulatesthe expression of various genes They further investigatedthe effect of nine promising plant extracts withheld fromthe first cell viability screening on NF120581B activation Thedichloromethane and methanol (1 1) extract of aerial part ofF vulgare revealed immunomodulatory NF120581B activities [82]Also Berrington and Lall investigated the in vitro cytotoxicityof acetone extracts of F vulgare and other eight medicinalplants against a noncancerous African green monkey kidney(Vero) cell line and an adenocarcinoma cervical cancer(HeLa) cell line [87]

424 Antipyretic Activity F vulgare extract showedantipyretic activity against hyperpyrexia in mice It wasinduced by SC administration of 2mL100 g of a 20aqueous suspension of brewerrsquos yeast As an antipyreticagent ethanolic extract of F vulgare fruit showed a moderateantipyretic activity that was statistically significant after 30and 90min (119875 lt 001) [108]

425 Hypolipidemic Activity The aqueous extract of F vul-gare revealed notable hypolipidemic and antiatherogenicactivity against Triton WR-1339 induced hyperlipidemiain mice Aqueous extract causes significant reduction ofplasma lipid levels that is cholesterol triglycerides LDL-cholesterol and apolipoprotein-B decreased by 40 2361 and 61 respectively and increase in HDL-cholesteroland apolipoprotein A1 by 85 and 58 respectively [88]

426 Hypoglycemic Activity The essential oil of F vulgareexhibits potential hypoglycemic and antioxidant activityagainst streptozotocin induced diabetes in rats Essentialoil (30mgkg body weight) of F vulgare works in the

correction of hyperglycemia from 1625 plusmn 319mgdL to8197 plusmn 197mgdL with 119875 lt 005 and the activity of serumglutathione peroxidase from 5972 plusmn 278Ug Hb to 9960 plusmn638Ug Hb with 119875 lt 005 Also essential oil of fennelimproves the pathological changes noticed in their kidneyand pancreas as compared with the control group of animalThis can prove its effect as antidiabetic in folk Medicine Thismakes the possibility of its inclusion in antidiabetic drugindustry [12]

427 Antispasmodic Activity The antispasmodic activity of25 and 100mLL of alcoholic extract of Foeniculum vulgarealong with other Germanic medicinal plants namelyMelissaofficinalis Rosmarinus officinalisMentha piperitaMatricariachamomilla Carum carvi and Citrus aurantium were testedemploying the guinea pig ileum and using acetylcholine andhistamine as spasmogens An alcoholic extract of the fruits ofFoeniculum vulgare possesses antispasmodic activity whichinhibits the acetylcholine and histamine-induced guineapig ileal contractions in vitro An essential oil which isobtained from the fruits of Foeniculum vulgare 25 120583gmL and10 120583gmL respectively inhibited oxytocin and prostaglandin[72]

428 Apoptotic Activity The apoptotic activities of ethanolextracts from fruits of seven species of Apiaceae familynamely Eryngium planum Archangelica officinalis Pasti-naca sativa Heracleum sibiricum Carum carvi Foenicu-lum vulgare and Levisticum officinale against ML-1mdashhumanacute myeloblastic leukaemia J-4501mdashhuman acute Tcell leukaemia EOLmdashhuman eosinophilic leukaemia HL-60mdashhuman Caucasian promyelocytic leukaemia 1301mdashhuman T cell leukaemia lymphoblast C-8166mdashhuman Tcell leukaemia U-266B1mdashhuman myeloma WICLmdashhumanCaucasian normal B cell and H-9mdashhuman T cell wereinvestigated with the help of Trypan blue assay and AnnexinV fluos assay [86] The ethanol extract from fruit F vulgareshowed the highest mortality in Trypan blue test for J45cell linemdash4 of viable cells and for C8166 cell linemdash100of mortality However the cells of other lines showed thehighest viability HL60mdash60 EOLmdash48 and MLmdash1ndash42The normal cell line H9 and WICL showed 35 and 25of viable cells respectively C8166 cell line and J-45 cell lineshowed the highest level of the apoptotic cells detected byAnnexin V methodmdash100 and 93 respectively Howeverthe cells of two lines HL60 and EOL-1 showed the lowerlevels of apoptotic cellsmdash52 and 60 respectively Highpercentage of apoptotic cells was observed inH9 andWICLmdash76 and 93 respectively [86]

429 Human Liver Cytochrome P450 3A4 Inhibitory ActivityThirteen compounds isolated from the methanolic extract offennel have been found to possess human liver cytochromeP450 3A4 inhibitory activity Among these compounds 5-methoxypsoralen (5-MoP) showed the strongest inhibitionwith an IC50 value of 183120583m and with a mixed type ofinhibition [83]

430 Antiaging Effects Rasul and his coworker developeda base and formulation containing 4 concentrated seedextract of F vulgare This formulation shows notable antiag-ing effect with supporting experimental data related to skinmoisture and transepidermal water loss (TEWL) The basewas insignificant while the formulation showed significanteffects on skin moisture and TEWL The texture parameterenergy showed a significant increase proving that the formu-lation possesses potential antiaging effects [50]

431 Bronchodilatory Effect Ethanol extract and essential oilfrom F vulgare exhibited bronchodilatory activity on con-tracted tracheal chains of guinea pig The potassium channelopening effect of fennel may contribute on its relaxant effecton guinea pig tracheal chains [111] Moreover anethole bearsa striking resemblance to the catecholamines epinephrinenorepinephrine and dopamine This structural similarityappears to be responsible for the various sympathomimeticactivities of F vulgare such as bronchodilatory effect [71]

432 Antioxidant Activities Naturally occurring antioxi-dants can be used to protect human beings from oxidativestress damage [112] Fennel was known as excellent source ofnatural antioxidants and contributed to the daily antioxidantdiet [113]Wild fennel was found to exhibit a free radical scav-enging activity with higher content phenolic and flavonoidthan medicinal and edible fennel and the aerial parts ofthe Italian fennel populations showed the highest DPPHscavenging activity [65] Phenolic compounds of fennelincluding caffeoylquinic acid rosmarinic acid eriodictyol-7-orutinoside quercetin-3-O-galactoside and kaempferol-3-O-glucoside showed antioxidant activities [67] The volatileoil showed strong antioxidant activity in comparison withbutyrated hydroxyanisole and butylated hydroxytolueneEthanol and water extracts of fennel showed less antioxidantactivity compared with essential oil [114]

5 Environmental Application

Foeniculum vulgare that is fennel not only exhibited phar-macological activities but also revealed a few environmentalactivities These activities play a key role in the managementof nematode insect mosquitoes and some harmful larvae ofmalaria producing vector Thus the extracts of F vulgare andisolated biologically active compounds have been evaluatedfor their insecticidal repellent acaricidal larvicidal andnematicidal activity [115ndash119] A brief review on the differenttype of ecofriendly environmental activities as reported onthis plant is summarized below

51 Insecticidal Activities The fruit derived phytoconstitu-ents of F vulgare exhibited prominent insecticidal activi-ties against Sitophilus oryzae Callosobruchus chinensis andLasioderma serricorne This activity was examined usingdirect contact application and fumigation methods Thebiologically active constituents that is phenylpropenes (E)-anethole and estragole and the monoterpene (+)-fenchonewere characterized from Foeniculum fruit By using a filter

26 BioMed Research International

paper diffusion test estragole (0168mg cmminus2) caused 91mortality to S oryzae within 1 day after treatment whereas(+)-fenchone and (E)-anethole gave over 90 mortality at 2and 4 day after treatment respectively

After 2 days of treatment all test compounds (0021mg cmminus2 concentration) revealed potent insecticidal activityagainst C chinensis Whereas after 1 day of treatment (E)-anethole (0105mg cmminus2) gave 100mortality of L serricornewhereas 90 and 60 mortality at 4 day after treatment wasachieved with estragole and (+)-fenchone respectively In afumigation test the compounds were much more effectiveagainst adults of S oryzae C chinensis and L serricorne inclosed cups than in open ones indicating that the insecticidalactivity of test compounds was largely attributable to fumi-gant action As naturally occurring insect-control agents theF vulgare fruit-derived materials described could be usefulfor managing field populations of S oryzae C chinensis andL serricorne [116]

52 Acaricidal Activity Fennel oil shows significant acaricid-al activity againstDermatophagoides farinae andDermatoph-agoides pteronyssinus (+)-fenchone and p-anisaldehyde aremajor constituents of fruit oil of F vulgare P-anisaldehydewas the most toxic compound against D farinae and is muchmore effective compared with benzyl benzoate thymol andestragol [118]

53 Repellent Activity The methanolic extract of fruits ofF vulgare was spectroscopically characterized for the pres-ence of biologically active constituents called (+)-fenchoneand (E)-9-octadecenoic acid The repellent activity of theseconstituents was tested against hungry Aedes aegypti femaleswith the help of skin and patch tests and compared withthat of the commercial repellent agent called NN-diethyl-m-toluamide (DEET) and (Z)-9-octadecenoic acid In askin test with female mosquitoes (+)-fenchone and (Z)-9-octadecenoic acid (04mgcm2) exhibitedmoderate repellentactivity at 30min after treatment whereas DEET providedgt1 h of protection against adult mosquitoes at (02mgcm2)Thus (+)-Fenchone and (E)-9-octadecenoic acid are poten-tial mosquito repellent agents or lead compounds [117]

54 Larvicidal Activity Plant extracts and oils may act asalternatives to conventional pesticides for malaria vectorcontrol By considering this aspect Sedaghat et al [119] inves-tigated the larvicidal activity of essential oils of three plantsof Apiaceae family against malaria vector called Anophe-les stephensi The larvicidal activity was evaluated againstlaboratory-reared larvae by standard method of WHO TheF vulgare oil was the most effective against A stephensiwith LC(50) and LC(90) values of 2010 and 4451 ppmrespectively [119] Additionally the essential oil extracts fromleaves flowers and roots of F vulgare exhibit noticeablelarvicidal activity against fourth-instar larvae of themosquitoCulex pipiens molestus Terpineol and 18-cineole content of Fvulgare are the most effective phytoconstituent against Culexpipiens molestus bites offering complete protection for 16 and2 h respectively [120] Recently Zoubiri et al [57] reported

the larvicidal activity of essential oil of fennel seed againstCulex pipiensmosquitoThus F vulgare can serve as a naturallarvicidal agent

55 Nematicidal Activity Oka et al investigated the in vitronematicidal activity of essential oils extracted from 27 spicesand aromatic plants in pot experiments Twelve of thetwenty-seven essential oils immobilized more than 80 ofjuveniles of the root-knot nematodeMeloidogyne javanica ata concentration of 1000 120583Lliter At this concentration mostof these oils also inhibited nematode hatching Essential oilsof Carum carvi Foeniculum vulgare Mentha rotundifoliaand Mentha spicata showed the highest nematicidal activityamong the in vitro tested oils In 3-liter pot experimentsnematicidal activity of the essential oils and their componentswas confirmed at 200 and 150mgkg respectivelyThe resultssuggest that the essential oils and theirmain componentsmayserve as nematicides [115]

6 Toxicity

The long history of ethnomedicinal application with noreports of any serious side effects suggests that F vulgarecould be considered as safe Inmost toxicity experiments car-ried out on F vulgare no sign of toxicity was observed Shahand his coworker in 1991 investigated the detailed toxicityaccount of ethanolic extract of fennel fruit in experimentalmice with respect to acute and 90 days longer term toxicity[121] In experimentation Shah and his coworker observedthe general symptoms of toxicity and mortality for only 24 hin acute toxicity Whereas in another part of toxicity theystudied the effect of fennel extract on mice with 90 dayslong term treatment Acute toxicity of ethanolic extract of Fvulgarewas assessed in 35mice by using three concentrationsnamely 05 1 and 3 gkg body weight In this investigation Fvulgare exhibited no signs of toxicity and no mortality wasobserved upto the dose level 3 gkg body weight In case oflonger term toxicity ethanolic extract of F vulgare (100mgkgbody weightday) was given in drinking water of animals(30 male and 30 female mice) All external morphologicalhaematological and spermatogenic changes in addition tobody and vital organ weights were recorded The extractcaused no significant chronic mortality as compared tocontrols during this investigation The treated male micegained significant weight during chronic treatment while aloss or no significant change in weight was noticed in thefemale mice treated with the same extract The extracts didnot show spermatotoxic effects Thus Shah and his coworkerconcluded that fennel extract is safe based on both acuteandor long term toxicity studies [121] Additionally the plantextract in doses of 05 1 and 3 gkg (orally) did not causeany deaths These doses do not show any type of toxicityagainst several parameters tested namely locomotor activitybizarre reactions sensitivity to sound social interaction tailposture aggressive behaviour ataxia paralysis convulsionstremors prostration exophthalmos pupil size defecationsalivation urination pattern of respiration nasal dischargecyanosis and piloerection Exceptionally only the 3 gkg dose

BioMed Research International 27

showed signs of reduced locomotor activity and piloerec-tion Otherwise all other parameters were negative [108]In another experiment of acute toxicity different solventextracts namely n-hexane methylene chloride ethyl acetateand methanol extracts of F vulgare upto 55 gkg concentra-tion did not revealed any kind of toxicity in mice LD50being 675 110 692 and 15 gkg for n-hexane methylenechloride ethyl acetate and methanol extracts respectively[68] The plant extract of F vulgare was administered orallyat a dose of 100 200 400 600 800 1000 and 2000mgkgof body weight of mice Each group of animals was undervisual observation for 10 days for the external behavior ofneurological toxicity created by plant extract Even the micereceiving highest dose of F vulgare extract did not show anymortality or toxicity demonstrating the safety profile of theplant extract [89]

The acute oral 50 LD50 for anethole in rats was foundto be 2090mgkg Repeated doses of one-third the LD50 ofanethole (695mgkg) given to rat caused mild liver lesionsIt would therefore appear that in normal therapeutic dosagesanethole would have minimal hepatotoxicity When anetholewas fed to rats daily for one year as 025 of the dietno hepatic damage was seen [122] The acute oral LD50 ofessential oil in rats is 1326mgkg [76] The use of F vulgareessential oil as a remedy for control of primary dysmenorrheaincreases concern about its potential teratogenicity due toits estrogen like activity Evaluation of teratogenicity ofessential oil using limb bud mesenchymal cells showed thatthe essential oil may have toxic effect on fetal cells butthere was no evidence of teratogenicity upto concentrationof 93mgmL of culture medium [123] The overall toxicitystudies carried out on F vulgare accounts for its safety at therecommended therapeutic doses

7 Conclusions

The available scientific research on Foeniculum vulgarehas shown that it is an important medicinal plant used ina wide range of ethnomedical treatments especially forabdominal pains antiemetic aperitif arthritis cancer colicin children conjunctivitis constipation depurative diarrheadieresis emmenagogue fever flatulence gastralgia gastritisinsomnia irritable colon kidney ailments as a laxativeleucorrhoea liver pain mouth ulcer and stomachache Thisplant has been in use for a long period of time withoutany documented serious adverse effects Studies carriedout in the past and present indicate that fennel possessesdiverse health benefits and are an important constituentof food Studies have shown that various extracts offennel possess a range of pharmacological actions such asantiaging antiallergic anticolitic antihirsutism anti-inflam-matory antimicrobial and antiviral antimutagenic antino-ciceptive antipyretic antispasmodic antistress antithromb-otic anxiolytic apoptotic cardiovascular chemomodulatoryaction cytoprotection and antitumor cytotoxicity diureticestrogenic properties expectorant galactogenic gastrointes-tinal effect hepatoprotective human liver cytochrome P4503A4 inhibitory hypoglycemic hypolipidemic memory-en-hancing property nootropic and oculohypotensive activity

supporting its traditional use However the most prominentand the well studied effects are the antimicrobial andantioxidant effects of essential oil of fennel in differentexperimental models The observed health benefits may becredited to the presence of the various phytochemicals likevolatile compounds flavonoids phenolic compounds fattyacids and amino acids

Fennel also contains mineral and trace elements likealuminum barium calcium cadmium cobalt chromiumcopper ironmagnesiummanganese nickel lead strontiumand zinc [124] fat soluble vitamins such as vitamins A Eand K water soluble vitamins like ascorbic acid thiamineriboflavin niacin and pyridoxine essential amino acidslike leucine isoleucine phenylalanine and tryptophane maycontribute to the myriad health beneficial effects at least inpart

Most of the pharmacological studies were conductedusing uncharacterized crude extracts of fennel It is difficultto reproduce the results of these studies and pinpoint thebioactive compounds Hence there is a need for chemi-cal standardization and bioactivity-guided identification ofbioactive compounds Among several classes of chemicalconstituents identified in fennel volatile components of fen-nel essential oil and phenolic compounds are assumed to bethe main bioactive compounds responsible for the majorityof its pharmacological effects However the vast traditionaluse and proven pharmacological activities of fennel indicatethat an immense scope still exists for its chemical explorationFuture studies should be focused on validating the mecha-nism of action responsible for the various beneficial effectsand also on understanding which plant based compounds areresponsible for the reported effectsThe required informationwhen available will enhance our knowledge and appreciationfor the use of fennel in our daily diet Also the outcomeof such chemical studies may further expand its existingtherapeutic potential

Thus there are many areas of research related to thisplant that need to be further explored to fully recognize itsbeneficial effects for society Factors such as geographical andseasonal variation play an important role in the authentica-tion of the chemical constituents responsible for the activitywhich also can be an area of interest Thus it is incumbenton researchers to fill the huge gap of insufficient knowledgeand create awareness among pharmacologists as well as inves-tigators towards providing better medicinal value derivedfrom this plant This can be fulfilled only by generatinginterest among the research community through writing ofcritical appraisals (paper) and extending the interdisciplinaryresearch area to focused studies on Foeniculum vulgare

3 Phytochemistry

Phytochemical research carried out on Foeniculum vulgarehas led to the isolation of fatty acids phenolic componentshydrocarbons volatile components and few other classesof secondary metabolites from its different parts (Figure 4)Mostly these phytochemicals are found in essential oil(Table 6) Some of the phytoconstituents of F vulgare werefind application as coloring and antiaging agents [49 50]They also have noteworthy biological and pharmacologicalactivities (Table 7)

31 Volatile Compounds Table 6 summarizes the volatilecompounds present in the essential oil of F vulgareThe aniseodor of F vulgare is due to its essential oil content It makesan excellent flavoring agent in various types of food and foodrelated productsThe essential oil of fennel has been reportedto contain more than 87 volatile compounds [51ndash57] Theaccumulation of these volatile compounds inside the plantis variable appearing practically in any of its parts namelyroots stem shoots flowers and fruits [58 59]Themolecularstructures of major volatile components of F vulgare seedessential oil have been illustrated in Figure 4

32 Flavonoids Flavonoids are generally considered as animportant category of antioxidants in the human dietFlavonoids are abundant in the plants of Apiaceae family Ithas been reported that the presence of flavonol glycosidesin fennel species is related to its morphological hetero-geneity and variation Total flavonoid content of hydroal-coholic extracts is about 123 plusmn 018mgg Flavonoids likeeriodictyol-7-rutinoside quercetin-3-rutinoside and ros-marinic acid have been isolated from F vulgare [65]Amongst the flavonoids present in F vulgare the most preva-lent are quercetin-3-glucuronide isoquercitrin quercetin-3-arabinoside kaempferol-3-glucuronide and kaempferol-3-arabinoside and isorhamnetin glucoside [66] Quercetin-3-O-galactoside kaempferol-3-O-rutinoside and kaempferol-3-O-glucoside have also been reported to occur in the aque-ous extract of F vulgare [67] The flavonoids like isorham-netin 3-O-120572-rhamnoside quercetin and kaempferol werealso isolated from the ethyl acetate extract whereas quercetin3-O-rutinoside kaempferol 3-O-rutinoside and quercetin3-O-120573-glucoside were isolated from the methanol extractThese flavonoids exhibit remarkable antinociceptive and anti-inflammatory activity [68] Further quercetin rutin andisoquercitrin were reported to have the immunomodulatoryactivities [69]

33 Phenolic Compounds There has been a growing interestin phenolic components of fruits and vegetables which maypromote human health or lower the risk of disease Aqueous

extract of fennel fruits are rich in phenolic compoundsMany of them have antioxidant activities and hepatopro-tective properties The phenolic compounds present in Fvulgare are considered to be associated with the preventionof diseases possibly induced by oxidative stress such ascardiovascular diseases cancer and inflammation Thesephenolic compounds have received tremendous attentionamong nutritionists food scientists and consumers dueto their role in human health Fennel has been reportedto contain hydroxyl cinnamic acid derivatives flavonoidglycosides and flavonoid aglycones [67] The methanolicextract of fennel seeds contains rosmarinic acid chlorogenicacids as major phenolic compounds (149 and 68 resp)and quercetin and apigenin as themajor flavonoids (171 and125 resp) Also the total phenolic compounds in fennelmethanol extract were higher than the flavonoid compounds[23] F vulgare has been reported to contain phenolic acidslike 3-O-caffeoylquinic acid 4-O-caffeoylquinic acid 5-O-caffeoylquinic acid 13-O-di-caffeoylquinic acid 14-O-di-caffeoylquinic acid and 15-O-di-caffeoylquinic acid [65]Two compounds A and B were isolated and character-ized for the first time from the wild fennel and identi-fied as 34-dihydroxyphenethylalchohol-6-O-caffeoyl-120573-D-glucopyranoside and 3101584081015840-binaringenin respectively Thetotal phenolic and flavonoid contents ofwild fennel (24 and12 resp) were less as compared to cultivated fennel (31and 16 resp) [70]

chloride crude extract of F vulgare [101] suggested thatthe crude extract containing monoterpenes could be a newmedicinal resource for antibacterial agents

A total of 78 compounds were identified from theactive antimycobacterial fraction of F vulgare with thehelp of gas chromatography-mass spectra (GC-MS) Outof these twenty compounds were tested against one sensi-tive and three MDR strains of Mycobacterium tuberculosisusing the Alamar Blue microassay Compounds that showedsome degree of antimycobacterial activity against all strainstested were the following linoleic acid (MIC 100 120583gmL)oleic acid (MIC 100 120583gmL) 13-benzenediol (MIC 100ndash200120583gmL) undecanal (MIC 50ndash200120583gmL) and 24-undecadienal (MIC 25ndash50120583gmL) 24-Undecadienal wasthe most active compound against multidrug resistant Mtuberculosis speciesThus the dietary intake of F vulgaremaylower the risk ofM tuberculosis infection [63]

Orhan et al [5] studied the antiviral activity of theessential oil of fruit sample of F vulgare along with 12other Turkish medicinal plants against the DNA virusHerpessimplex type-1 (HSV-1) and the RNA virus parainfluenzatype-3 (PI-3) Most of the oils and compounds displayedstrong antiviral effects against HSV-1 ranging between 08and 0025 120583gmL However the samples tested were lesseffective against PI-3 with results ranging between 16 and02 120583gmL Only the essential oils of Anethum graveolensFoeniculum vulgare (fully mature) Mentha piperita Menthaspicata Ocimum minutiflorum Ocimum vulgaris and Sat-ureja cuneifolia inhibited this virus significantly

All these literature findings validated the traditional usesof Foeniculum vulgare in infectious disorders like abdomi-nal pains antiemetic arthritis conjunctivitis constipationdepurative diarrhea dieresis fever flatulence gastralgia gas-tritis insomnia irritable colon mouth ulcer stomachacherespiratory disorders skin diseases and so forth There isalways a need for new antimicrobial agents due to rapiddevelopment of resistance Bioactive metabolites of F vulgaremay be a potential source for new antimicrobial agents

42 Anti-Inflammatory Activity Oral administration ofmethanol extract of F vulgare fruit to rat and mice exhibitedinhibitory effects against acute and subacute inflammatorydiseases The anti-inflammatory activity of methanol extractwas evaluated by using three screening protocols namelycarrageenan-induced paw edema arachidonic acid-inducedear edema and formaldehyde-induced arthritis Theseare widely used for testing nonsteroidal anti-inflammatorydrugs For acute inflammationmethanol extract (200mgkg)exhibits significant inhibition of paw edema (69) inducedby carrageenan injection as compared to the control groupof animals Methanol extract of F vulgare also inhibitsear-edema (70) induced by arachidonic acid in mice Thelevel of serum transaminase aspartate aminotransferase(AST) and alanine aminotransferase (ALT) significantlyincreases in the presence of methanolic extract of F vulgareon inflammation induced by formaldehyde as comparedto control group The assessment of the level of AST and

ALT provides a good and simple tool to measure the anti-inflammatory activity of the target compounds [102] Theseoverall results seem to suggest that F vulgare FME mayact on both the cyclooxygenase and lipoxygenase pathways[79]

43 Antiallergic Activity Methanolic extract of F vulgarefruit showed significant inhibitory effect on DNFB- (24-dinitrofluorobenzene-) induced delayed type hypersensitiv-ity after oral administration of 200mgkg once a day for7 days The inhibitory effect on immunologically inducedswelling suggests the possible immunosuppressive propertiesof F vulgare [79]

44 Hepatoprotective Activity Essential oil of F vulgareseeds revealed a potent hepatoprotective effect against acutehepatotoxicity produced by carbon tetrachloride in ratsOral administration of F vulgare essential oil decreases thelevels of serum aspartate aminotransferase (AST) alanineaminotransferase (ALT) alkaline phosphatase (ALP) andbilirubin as compared to the control group Ozbek et alsuggest that the constituents (d-limonene and 120573-myrcene) ofessential oil may have played a key role in the protection ofliver from CCl

4toxicity [9]

45 Anxiolytic Activity Anxiety is the unpleasant feeling offear and concern When anxiety becomes excessive it maybe considered as an anxiety disorder Anxiolytic fennel isa drug used for the treatment of anxiety and its relatedpsychological and physical symptoms Naga Kishore et al[89] investigated the anxiolytic activity of ethanolic extract ofF vulgare fruit with the help of elevated plus maze rota rodopen field test and whole board models The 100 to 200mgdose of extract per kg of body weight of animal revealedsignificant activity when compared to reference anxiolyticdrug called diazepam (1mgkg) Thus fennel extract maypossess anxiolytic activity supporting its traditional claimabout anxiolytic activity reported in 19th edition of Pharma-cology and Pharmacotherapeutics by Sathodkar Bhandarkarand Rege

46 Antistress Activity Drug and food of natural originplay a significant role in public healthcare systems and arebeing investigated as remedies for a number of stress-relateddisorders [103]Thewhole plant extract of F vulgare exhibitednotable antistress effect against stress induced by forcefulswimming of test animals The key parameters that isurinary levels of vanillyl mandelic acid (VMA) and ascorbicacid in rats were used to evaluate antistress activity Theplant extract (50 100 and 200mgkg body weight) showeda significant improvement in urinary levels of VMA (119875 lt0001) and ascorbic acid excretion levels (119875 lt 0001) in testanimals when compared to the normal basal levels in controlgroup of animalsThus the extract of entire plant of F vulgareacts as an antistress agent [13]

47 Memory-Enhancing Property There are a number ofplants whose consumption is believed to enhance memory

22 BioMed Research International

and intelligence These were usually given to children as partof their food F vulgaris an ayurvedic rasayana (mixture)possessing multiple neuropharmacological activities Theantidepressant activity of fennel has been well documentedin ethnomedicine The whole plants extract (50 100 and200mgkg) of F vulgare exhibited memory-enhancing effectagainst scopolamine-induced amnesic rats This experimentwas evaluated by conditioned avoidance response (CAR)technique The CAR of rats administered with the extractincreased gradually to 95 over 7 to 12 days The acquisition(time to achieve 95 CAR) for rats administered with theextract was dose- and time-dependent compared to controlgroup which took 12 days for acquisition The percentavoidance was always higher in the extract-treated groupsas compared to control group Animals receiving 200mgkgbody weight of the extract took ten days while groups treatedwith 100 and 50mgkg doses of the extract required elevenand twelve days respectively to reach the point of acquisitionAdministration of scopolamine produced amnesia as seenfrom reduction in the observed CAR Amnesia was greaterin the control group than in extract-treated groups How-ever continued treatment with F vulgare produced betterretention and recovery in a dose-dependent manner thanthe vehicle-treated animals Recovery from scopolamine-induced amnesia in the extract-treated groups took 3ndash5 dayswhen compared to normal (control) group which took over6 days This overall progress suggests that F vulgare extractpossesses memory-enhancing property [13]

48 Nootropic Activity Alzheimerrsquos disease is a neurode-generative disorder associated with a decline in cognitiveabilities Dementia is one of the age-related mental problemsand a characteristic symptom of Alzheimerrsquos disease Thereis some evidence in favor of use of F vulgare for the treat-ment of cognitive disorders like dementia and Alzheimerrsquosdisease Methanol extract of the whole plant of F vul-gare administered for eight successive days ameliorated theamnesic effect of scopolamine and aging-induced memorydeficits inmiceThis extract increased step-down latency andacetylcholinesterase inhibition in mice significantly Thus Fvulgaremay be employed in treatment of cognitive disorderssuch as dementia and Alzheimerrsquos disease as a nootropic andanticholinesterase agent [80]

49 Antihirsutism Activity Idiopathic hirsutism is definedas the occurrence of excessive male pattern hair growth inwomen who have a normal ovulatory menstrual cycle andnormal levels of serum androgens It may be a disorder ofperipheral androgen metabolism Traditionally Foeniculumvulgare has been used as an estrogenic agent It has beenreputed to increase milk secretion promote menstruationfacilitate birth and increase libido On considering aboveaspect Javidnia and his research team evaluated the antihir-sutism activity of ethanolic extract of F vulgare seed againstidiopathic hirsutism by preparing cream containing 1 and 2of fennel extract The efficacy of treatment with the creamcontaining 2 fennel is better than the cream containing 1fennel and these two were more potent than placebo (control

group) The mean values of hair diameter reduction were78 183 and minus05 for patients receiving the creamscontaining 1 2 and 0 (placebo) respectively [78]

410 Estrogenic Properties Since the discovery of the estrusinducing effects of some plant products in 1926 consider-able effort has been devoted towards the characterizationof phytoestrogens including flavonoids isoflavonoids chal-cones coumestans stilbenes lignans saponins and essentialoils [16] F vulgare has estrogen-like activity In male ratstotal concentration of protein was found to be significantlydecreased in testes and in vasa deferentia whereas increasedin seminal vesicles and in prostate gland On the otherhand simultaneous decrease in the activities of acid andalkaline phosphatase in all these regions (except that alka-line phosphatase was unchanged in vasa) due to the oraladministration of acetone extract of F vulgare fruit wasobserved In female rats oral administration of the extract for10 days led to vaginal cornification and oestrus cycle [8] Totalconcentration of nucleic acids and protein as well as the organweights increased in both the tissues namely mammaryglands and oviducts due to the oral administration of acetoneextract (50 150 and 250120583g100 g body wt) of F vulgare seeds[104] Fennel oil was reported to exhibit estrogenic activitypromote menstruation and alleviate the symptoms of femaleclimacteric and increase libido [71] Administration of fenneloil (25 and 50 120583gmL final concentration in the organ bath)failed to exhibit any remarkable effect in uterine contrac-tion While 10 20 and 40 120583gml concentration of fennel oilrevealed significant inhibitory effect against prostaglandinE2 Fennel oil significantly reduces the frequency of uterinecontraction induced by prostaglandin E2 Thus the extractsof F vulgare have strong estrogenic activity [76]

411 Galactogenic Activity Foeniculum vulgare has been usedformillennia to increasemilk secretion [105]Thus F vulgarebelongs to galactagogue substance Structural similarity ofits main constituent anethole to dopamine seems to beresponsible for galactogenic activityDopamine acts to inhibitthe secretion of the milk-producing hormone prolactinAnethole might influence milk secretion by competing withdopamine at the appropriate receptor sites thereby inhibitingthe antisecretory action of dopamine on prolactin [71] It wasreported that anol (demethylated anethole) causes growthof the lobule-alveolar system in the mammary glands ofimmature female rabbits and induces menstruation in miceand other experimental animals Anol also gave positiveresults in the Jadassohn nipple test a test which involvesthe measurement of changes induced in the nipples ofguinea pigs subjected to the cutaneous application of sexhormones However further research suggests that the actualpharmacologically active agents responsible for galactogenicactivity are polymers of anethole such as dianethole andphotoanethole rather than anol or anethole itself [20 76]

412 Expectorant Activity F vulgare seeds stimulate theciliary motility of the respiratory apparatus and enhance the

BioMed Research International 23

external transport of extraneous corpuscles This action sug-gests a use for fennel in treating bronchial and bronchopul-monary afflictions and in particularly polluted environments[106] The volatile oil of F vulgare stimulates the contractionof the smooth muscles of the trachea an action that couldfacilitate the expectoration of mucus bacteria and othercorpuscles extraneous to the respiratory tracts [74]

413 Anticolitic Activity Essential oil of fennel regulates themotility of smooth muscles of the intestine while at thesame time reducing intestinal gas Alone or combined withother plant medicinals Foeniculum vulgare is indicated in thetreatment of spastic gastrointestinal disturbances in someforms of chronic colitis (which resist other treatments) indyspepsias from gastrointestinal atony in dyspepsias withthe sensation of heaviness in the stomach and so forthTheaddition of fennel to preparations containing anthraquinoniccomponents reduces the occurrence of abdominal pain oftenassociated with this type of laxative [73]

414 Antinociceptive Activity Antinociceptive means anysubstance that inhibits nociception which is a physiologicalprocess underlying the sensation of pain Briefly it reducesthe sensitivity to painful stimuli The various extracts ofaerial part of F vulgare namely hexane methylene chlorideethyl acetate and methanolic extract showed remarkableantinociceptive activity against acetic acid induced writhingin mice [68] The methanolic extract of the aerial parts ofF vulgare exhibited the highest antinociceptive activity at adose level of 2000mgkg while the activity exhibited by theethyl acetate extract was at dose level 800mgkgOn the otherhand n-hexane extract (700mgkg) and methylene chlorideextract (500mgkg) exhibited similar antinociceptive activi-ties being less than peripheral antinociceptive reference drug(acetyl salicylic acid) [68]

415 Diuretic Activity A diuretic is any substance thatpromotes the production of urine Briefly it is an agentthat promotes diuresis Diuretics work by promoting theexpulsion of urine (measured as the urine volume [UV]excreted) and urinary sodium (UNa) from the body and thishelps reduce the volume of blood circulating through thecardiovascular system Caceres et al [107] performed a studyin conscious animals and administered a powdered extractof the whole plant (F vulgare) which had no effect on UVor UNa The ethanolic extract of F vulgare fruit revealedexcellent diuretic activity and proves the earlier folk claimof F vulgare which was reported in the United State ofAmerica (Table 5) The fruit extract showed statistically ahighly significant diuretic effect F vulgare induced diuresis(500mgkg dose)was comparable to that of reference diureticagent urea (960mgkg dose) in mice with a urine outputthat was almost double that of the control group Thediuresis was not associated with changes in sodium andorpotassium excretion [108] In another part of the study theauthors showed that Foeniculum vulgare had little effect onthe noradrenalin contractile responses of aortic rings thus

suggesting that it worked mainly as a diuretic and natriureticwith little effect on arterial vascular tone [77]

416 Cardiovascular Activity An aqueous extract of F vul-gare leaves possesses potential cardiovascular action Thiseffect was investigated using pentobarbital-anaesthetisedmale albino Sprague-Dawley rats [75] An intravenousadministration of the lyophilized boiled water extract ofleaves produced a significant dose-related reduction in arte-rial blood pressure without affecting the heart rate or respi-ratory rate On the other hand the nonboiled aqueous extractshowed very little hypotensive activityThe hypotensive effectof the boiling water extract appeared not to be mediated viaadrenergicmuscarinic ganglionic or serotonergic receptorshowever histamine antagonists inhibited the hypotensiveeffect in a dose-related manner [75]

417 Oculohypotensive Activity The aqueous seed extract ofF vulgare demonstrated significant oculohypotensive activityusing water loading and steroid induced glaucoma modelThis extract exhibited 1749 2116 and 2203 reduction ofintraocular pressure in normotensive rabbits at 03 06and 12 (wv) concentrations respectively A maximummean difference of 3120 was observed between vehiclestreated and extracts treated eyes in water loading experi-mental animal model while a maximum mean intraocularpressure lowering of 3129 was observed in steroid inducedmodel of glaucoma Thus the aqueous extract of F vulgarerevealed oculohypotensive activity which was found to be asgood as that of reference standard antiglaucoma drugs calledtimolol [84]

418 Antithrombotic Activity Tognolini et al [55] providedevidence of potent inhibitory activity of essential oil of F vul-gare against platelet aggregation induced byADP arachidonicacid and collagen in guinea pig plasma Similar findingswere reported by Yoshioka and Tamada [109] for aggregationof rabbit platelets by an aromatic factor of fennel oil Theessential oil and anethole (a constituent of oil) of F vulgaretested in vitro in rat aorta with or without endotheliumdisplayed comparable NO-independent vasorelaxant activityat antiplatelet concentrations It supports the safety of Fvulgare that is free from cytotoxic effects Anethole and Fvulgare did not cause cytotoxicity when incubated for 30minupto 300 120583gmL in platelet viability test This concentrationwas largely compatible with those adopted in the functionalin vitro tests In vivo both F vulgare essential oil andanethole orally administered in a subacute treatment to mice(30mgkgday for 5 days) showed significant antithrom-botic activity preventing the paralysis induced by collagen-epinephrine intravenous injection (70 and 83 protectionresp)Thus essential oil and its main component anethole ofF vulgare showed a safe antithrombotic activity in guinea pigplasma that seems due to their broad spectrum antiplateletactivity clot destabilizing effect and vasorelaxant action [55]

419 Antimutagenic Effect Essential oil of F vulgare revealednoteworthy protective effects against genotoxicity in mice

induced by cyclophosphamide Genotoxicity and cytotoxicitywere assessed by using mice bone marrow chromosomalaberration micronucleus and sperm abnormality assaysrespectively Oral administration of essential oil (1 and2mLkg) significantly inhibited the frequencies of aberrantmetaphases chromosomal aberrations micronuclei forma-tion and cytotoxicity in mouse bone marrow cells inducedby cyclophosphamide and also produced a significant reduc-tion of abnormal sperm and antagonized the reduction ofcyclophosphamide induced superoxide dismutase catalaseand glutathione activities and inhibited increased malondi-aldehyde content in the liver Additionally F vulgare inhibitsthe oxidative stress induced by cyclophosphamide [90]

420 Gastrointestinal Effect Theaqueous extract of F vulgareshowed remarkable antiulcerogenic effect against ethanol-induced gastric lesions in rats It was found that pretreatmentwith aqueous extract significantly reduced ethanol-inducedgastric damageThis effect of aqueous extract was highest andstatistically significant in 300mgkg group comparedwith thecontrol (119875 lt 0001) group of animal Additionally aqueousextract of F vulgare significantly reduced the whole bloodmalondialdehyde levels while significantly increased nitritenitrate ascorbic acid retinol and beta-carotene levels Thusaqueous extract of F vulgare fruit had clearly a protectiveeffect against ethanol-induced gastric mucosal lesion in rats[81]

421 Chemomodulatory Action The chemopreventive effectof different doses of test diet of Foeniculum vulgare seeds wasexamined against 712-dimethylbenz(a)anthracene- (DMBA-) induced skin papillomagenesis and benzo(a)pyrene-[B(a)P-] induced forestomach papillomagenesis at the peri-initiational level in Swiss albino mice Fennel seeds exhibita significant reduction in the skin and the fore-stomachtumor incidence and tumor multiplicity as compared tothe control group Further biochemical assays showeda significant increase in the contentactivities of phase Ienzymes especially in the case of 6 test diet A concomitantincrease in the activities of the phase II enzymes wasobserved with all the doses of test diet under study Asignificant enhancement in the activities of antioxidantenzymes was observed especially at 4 and 6 test diets offennel These findings were indicative of chemopreventivepotential of fennel against carcinogenesis This is the firstreport showing chemopreventive potential of seeds of fennelagainst carcinogenesis [85]

422 Cytoprotection and Antitumor Activity Anethole is theprincipal active component of fennel seeds which has exhib-ited anticancer activity Al-Harbi et al studied the antitumoractivity of anethole against Ehrlich ascites carcinoma inducedin a tumor model in Swiss albino mice The study revealedthat anethole increased survival time reduced tumor weightand reduced the volume and body weight of the Ehrlichascites tumour-bearing mice It also produced a significantcytotoxic effect in the Ehrlich ascites tumour cells in the pawreduced the levels of nucleic acids and malondialdehyde and

increased glutathione concentrations [110] In vitro cytopro-tection activity of methanolic extract of Foeniculum vulgarewas evaluated against normal human blood lymphocytes bymicronucleus assay and antitumor activity against B16F10melanoma cell line by Trypan blue exclusion assay for cellviability Lymphocyte culture treated with 70 methanolicextract of Foeniculum vulgare showed very less percentage ofmicronucleus that is 0006 as compared to standard drugdoxorubicin which showed 0018 micronucleus On theother hand 70methanolic extract of Foeniculum vulgare haspotent antitumor activity at the concentration of 200120583gmLThe results suggest that the Foeniculum vulgare could beconsidered as a natural resource of antitumor agents as wellas cytoprotective to normal cells [11]

423 Cytotoxicity Kaileh and his coworker investigated thecytotoxic effect of organic extracts of 24 selected Palestinianmedicinal plant species The plant selection was based onexisting ethnobotanic information and interviews with localhealers The extracts of the plants under investigation weretested for their potential antitumor (cytotoxic) effect on themurine fibrosarcoma L929sA cells and on the human breastcancer cells MDA-MB231 and MCF7 The extract from Fvulgare presented an IC (50) value at 24 h of 700 plusmn 28 and500plusmn17 120583gmL on L929sA andMCF7 cells respectivelyThenuclear transcription factor NFkappaB or NF120581B regulatesthe expression of various genes They further investigatedthe effect of nine promising plant extracts withheld fromthe first cell viability screening on NF120581B activation Thedichloromethane and methanol (1 1) extract of aerial part ofF vulgare revealed immunomodulatory NF120581B activities [82]Also Berrington and Lall investigated the in vitro cytotoxicityof acetone extracts of F vulgare and other eight medicinalplants against a noncancerous African green monkey kidney(Vero) cell line and an adenocarcinoma cervical cancer(HeLa) cell line [87]

424 Antipyretic Activity F vulgare extract showedantipyretic activity against hyperpyrexia in mice It wasinduced by SC administration of 2mL100 g of a 20aqueous suspension of brewerrsquos yeast As an antipyreticagent ethanolic extract of F vulgare fruit showed a moderateantipyretic activity that was statistically significant after 30and 90min (119875 lt 001) [108]

425 Hypolipidemic Activity The aqueous extract of F vul-gare revealed notable hypolipidemic and antiatherogenicactivity against Triton WR-1339 induced hyperlipidemiain mice Aqueous extract causes significant reduction ofplasma lipid levels that is cholesterol triglycerides LDL-cholesterol and apolipoprotein-B decreased by 40 2361 and 61 respectively and increase in HDL-cholesteroland apolipoprotein A1 by 85 and 58 respectively [88]

426 Hypoglycemic Activity The essential oil of F vulgareexhibits potential hypoglycemic and antioxidant activityagainst streptozotocin induced diabetes in rats Essentialoil (30mgkg body weight) of F vulgare works in the

correction of hyperglycemia from 1625 plusmn 319mgdL to8197 plusmn 197mgdL with 119875 lt 005 and the activity of serumglutathione peroxidase from 5972 plusmn 278Ug Hb to 9960 plusmn638Ug Hb with 119875 lt 005 Also essential oil of fennelimproves the pathological changes noticed in their kidneyand pancreas as compared with the control group of animalThis can prove its effect as antidiabetic in folk Medicine Thismakes the possibility of its inclusion in antidiabetic drugindustry [12]

427 Antispasmodic Activity The antispasmodic activity of25 and 100mLL of alcoholic extract of Foeniculum vulgarealong with other Germanic medicinal plants namelyMelissaofficinalis Rosmarinus officinalisMentha piperitaMatricariachamomilla Carum carvi and Citrus aurantium were testedemploying the guinea pig ileum and using acetylcholine andhistamine as spasmogens An alcoholic extract of the fruits ofFoeniculum vulgare possesses antispasmodic activity whichinhibits the acetylcholine and histamine-induced guineapig ileal contractions in vitro An essential oil which isobtained from the fruits of Foeniculum vulgare 25 120583gmL and10 120583gmL respectively inhibited oxytocin and prostaglandin[72]

428 Apoptotic Activity The apoptotic activities of ethanolextracts from fruits of seven species of Apiaceae familynamely Eryngium planum Archangelica officinalis Pasti-naca sativa Heracleum sibiricum Carum carvi Foenicu-lum vulgare and Levisticum officinale against ML-1mdashhumanacute myeloblastic leukaemia J-4501mdashhuman acute Tcell leukaemia EOLmdashhuman eosinophilic leukaemia HL-60mdashhuman Caucasian promyelocytic leukaemia 1301mdashhuman T cell leukaemia lymphoblast C-8166mdashhuman Tcell leukaemia U-266B1mdashhuman myeloma WICLmdashhumanCaucasian normal B cell and H-9mdashhuman T cell wereinvestigated with the help of Trypan blue assay and AnnexinV fluos assay [86] The ethanol extract from fruit F vulgareshowed the highest mortality in Trypan blue test for J45cell linemdash4 of viable cells and for C8166 cell linemdash100of mortality However the cells of other lines showed thehighest viability HL60mdash60 EOLmdash48 and MLmdash1ndash42The normal cell line H9 and WICL showed 35 and 25of viable cells respectively C8166 cell line and J-45 cell lineshowed the highest level of the apoptotic cells detected byAnnexin V methodmdash100 and 93 respectively Howeverthe cells of two lines HL60 and EOL-1 showed the lowerlevels of apoptotic cellsmdash52 and 60 respectively Highpercentage of apoptotic cells was observed inH9 andWICLmdash76 and 93 respectively [86]

429 Human Liver Cytochrome P450 3A4 Inhibitory ActivityThirteen compounds isolated from the methanolic extract offennel have been found to possess human liver cytochromeP450 3A4 inhibitory activity Among these compounds 5-methoxypsoralen (5-MoP) showed the strongest inhibitionwith an IC50 value of 183120583m and with a mixed type ofinhibition [83]

430 Antiaging Effects Rasul and his coworker developeda base and formulation containing 4 concentrated seedextract of F vulgare This formulation shows notable antiag-ing effect with supporting experimental data related to skinmoisture and transepidermal water loss (TEWL) The basewas insignificant while the formulation showed significanteffects on skin moisture and TEWL The texture parameterenergy showed a significant increase proving that the formu-lation possesses potential antiaging effects [50]

431 Bronchodilatory Effect Ethanol extract and essential oilfrom F vulgare exhibited bronchodilatory activity on con-tracted tracheal chains of guinea pig The potassium channelopening effect of fennel may contribute on its relaxant effecton guinea pig tracheal chains [111] Moreover anethole bearsa striking resemblance to the catecholamines epinephrinenorepinephrine and dopamine This structural similarityappears to be responsible for the various sympathomimeticactivities of F vulgare such as bronchodilatory effect [71]

432 Antioxidant Activities Naturally occurring antioxi-dants can be used to protect human beings from oxidativestress damage [112] Fennel was known as excellent source ofnatural antioxidants and contributed to the daily antioxidantdiet [113]Wild fennel was found to exhibit a free radical scav-enging activity with higher content phenolic and flavonoidthan medicinal and edible fennel and the aerial parts ofthe Italian fennel populations showed the highest DPPHscavenging activity [65] Phenolic compounds of fennelincluding caffeoylquinic acid rosmarinic acid eriodictyol-7-orutinoside quercetin-3-O-galactoside and kaempferol-3-O-glucoside showed antioxidant activities [67] The volatileoil showed strong antioxidant activity in comparison withbutyrated hydroxyanisole and butylated hydroxytolueneEthanol and water extracts of fennel showed less antioxidantactivity compared with essential oil [114]

5 Environmental Application

Foeniculum vulgare that is fennel not only exhibited phar-macological activities but also revealed a few environmentalactivities These activities play a key role in the managementof nematode insect mosquitoes and some harmful larvae ofmalaria producing vector Thus the extracts of F vulgare andisolated biologically active compounds have been evaluatedfor their insecticidal repellent acaricidal larvicidal andnematicidal activity [115ndash119] A brief review on the differenttype of ecofriendly environmental activities as reported onthis plant is summarized below

51 Insecticidal Activities The fruit derived phytoconstitu-ents of F vulgare exhibited prominent insecticidal activi-ties against Sitophilus oryzae Callosobruchus chinensis andLasioderma serricorne This activity was examined usingdirect contact application and fumigation methods Thebiologically active constituents that is phenylpropenes (E)-anethole and estragole and the monoterpene (+)-fenchonewere characterized from Foeniculum fruit By using a filter

26 BioMed Research International

paper diffusion test estragole (0168mg cmminus2) caused 91mortality to S oryzae within 1 day after treatment whereas(+)-fenchone and (E)-anethole gave over 90 mortality at 2and 4 day after treatment respectively

After 2 days of treatment all test compounds (0021mg cmminus2 concentration) revealed potent insecticidal activityagainst C chinensis Whereas after 1 day of treatment (E)-anethole (0105mg cmminus2) gave 100mortality of L serricornewhereas 90 and 60 mortality at 4 day after treatment wasachieved with estragole and (+)-fenchone respectively In afumigation test the compounds were much more effectiveagainst adults of S oryzae C chinensis and L serricorne inclosed cups than in open ones indicating that the insecticidalactivity of test compounds was largely attributable to fumi-gant action As naturally occurring insect-control agents theF vulgare fruit-derived materials described could be usefulfor managing field populations of S oryzae C chinensis andL serricorne [116]

52 Acaricidal Activity Fennel oil shows significant acaricid-al activity againstDermatophagoides farinae andDermatoph-agoides pteronyssinus (+)-fenchone and p-anisaldehyde aremajor constituents of fruit oil of F vulgare P-anisaldehydewas the most toxic compound against D farinae and is muchmore effective compared with benzyl benzoate thymol andestragol [118]

53 Repellent Activity The methanolic extract of fruits ofF vulgare was spectroscopically characterized for the pres-ence of biologically active constituents called (+)-fenchoneand (E)-9-octadecenoic acid The repellent activity of theseconstituents was tested against hungry Aedes aegypti femaleswith the help of skin and patch tests and compared withthat of the commercial repellent agent called NN-diethyl-m-toluamide (DEET) and (Z)-9-octadecenoic acid In askin test with female mosquitoes (+)-fenchone and (Z)-9-octadecenoic acid (04mgcm2) exhibitedmoderate repellentactivity at 30min after treatment whereas DEET providedgt1 h of protection against adult mosquitoes at (02mgcm2)Thus (+)-Fenchone and (E)-9-octadecenoic acid are poten-tial mosquito repellent agents or lead compounds [117]

54 Larvicidal Activity Plant extracts and oils may act asalternatives to conventional pesticides for malaria vectorcontrol By considering this aspect Sedaghat et al [119] inves-tigated the larvicidal activity of essential oils of three plantsof Apiaceae family against malaria vector called Anophe-les stephensi The larvicidal activity was evaluated againstlaboratory-reared larvae by standard method of WHO TheF vulgare oil was the most effective against A stephensiwith LC(50) and LC(90) values of 2010 and 4451 ppmrespectively [119] Additionally the essential oil extracts fromleaves flowers and roots of F vulgare exhibit noticeablelarvicidal activity against fourth-instar larvae of themosquitoCulex pipiens molestus Terpineol and 18-cineole content of Fvulgare are the most effective phytoconstituent against Culexpipiens molestus bites offering complete protection for 16 and2 h respectively [120] Recently Zoubiri et al [57] reported

the larvicidal activity of essential oil of fennel seed againstCulex pipiensmosquitoThus F vulgare can serve as a naturallarvicidal agent

55 Nematicidal Activity Oka et al investigated the in vitronematicidal activity of essential oils extracted from 27 spicesand aromatic plants in pot experiments Twelve of thetwenty-seven essential oils immobilized more than 80 ofjuveniles of the root-knot nematodeMeloidogyne javanica ata concentration of 1000 120583Lliter At this concentration mostof these oils also inhibited nematode hatching Essential oilsof Carum carvi Foeniculum vulgare Mentha rotundifoliaand Mentha spicata showed the highest nematicidal activityamong the in vitro tested oils In 3-liter pot experimentsnematicidal activity of the essential oils and their componentswas confirmed at 200 and 150mgkg respectivelyThe resultssuggest that the essential oils and theirmain componentsmayserve as nematicides [115]

6 Toxicity

The long history of ethnomedicinal application with noreports of any serious side effects suggests that F vulgarecould be considered as safe Inmost toxicity experiments car-ried out on F vulgare no sign of toxicity was observed Shahand his coworker in 1991 investigated the detailed toxicityaccount of ethanolic extract of fennel fruit in experimentalmice with respect to acute and 90 days longer term toxicity[121] In experimentation Shah and his coworker observedthe general symptoms of toxicity and mortality for only 24 hin acute toxicity Whereas in another part of toxicity theystudied the effect of fennel extract on mice with 90 dayslong term treatment Acute toxicity of ethanolic extract of Fvulgarewas assessed in 35mice by using three concentrationsnamely 05 1 and 3 gkg body weight In this investigation Fvulgare exhibited no signs of toxicity and no mortality wasobserved upto the dose level 3 gkg body weight In case oflonger term toxicity ethanolic extract of F vulgare (100mgkgbody weightday) was given in drinking water of animals(30 male and 30 female mice) All external morphologicalhaematological and spermatogenic changes in addition tobody and vital organ weights were recorded The extractcaused no significant chronic mortality as compared tocontrols during this investigation The treated male micegained significant weight during chronic treatment while aloss or no significant change in weight was noticed in thefemale mice treated with the same extract The extracts didnot show spermatotoxic effects Thus Shah and his coworkerconcluded that fennel extract is safe based on both acuteandor long term toxicity studies [121] Additionally the plantextract in doses of 05 1 and 3 gkg (orally) did not causeany deaths These doses do not show any type of toxicityagainst several parameters tested namely locomotor activitybizarre reactions sensitivity to sound social interaction tailposture aggressive behaviour ataxia paralysis convulsionstremors prostration exophthalmos pupil size defecationsalivation urination pattern of respiration nasal dischargecyanosis and piloerection Exceptionally only the 3 gkg dose

BioMed Research International 27

showed signs of reduced locomotor activity and piloerec-tion Otherwise all other parameters were negative [108]In another experiment of acute toxicity different solventextracts namely n-hexane methylene chloride ethyl acetateand methanol extracts of F vulgare upto 55 gkg concentra-tion did not revealed any kind of toxicity in mice LD50being 675 110 692 and 15 gkg for n-hexane methylenechloride ethyl acetate and methanol extracts respectively[68] The plant extract of F vulgare was administered orallyat a dose of 100 200 400 600 800 1000 and 2000mgkgof body weight of mice Each group of animals was undervisual observation for 10 days for the external behavior ofneurological toxicity created by plant extract Even the micereceiving highest dose of F vulgare extract did not show anymortality or toxicity demonstrating the safety profile of theplant extract [89]

The acute oral 50 LD50 for anethole in rats was foundto be 2090mgkg Repeated doses of one-third the LD50 ofanethole (695mgkg) given to rat caused mild liver lesionsIt would therefore appear that in normal therapeutic dosagesanethole would have minimal hepatotoxicity When anetholewas fed to rats daily for one year as 025 of the dietno hepatic damage was seen [122] The acute oral LD50 ofessential oil in rats is 1326mgkg [76] The use of F vulgareessential oil as a remedy for control of primary dysmenorrheaincreases concern about its potential teratogenicity due toits estrogen like activity Evaluation of teratogenicity ofessential oil using limb bud mesenchymal cells showed thatthe essential oil may have toxic effect on fetal cells butthere was no evidence of teratogenicity upto concentrationof 93mgmL of culture medium [123] The overall toxicitystudies carried out on F vulgare accounts for its safety at therecommended therapeutic doses

7 Conclusions

The available scientific research on Foeniculum vulgarehas shown that it is an important medicinal plant used ina wide range of ethnomedical treatments especially forabdominal pains antiemetic aperitif arthritis cancer colicin children conjunctivitis constipation depurative diarrheadieresis emmenagogue fever flatulence gastralgia gastritisinsomnia irritable colon kidney ailments as a laxativeleucorrhoea liver pain mouth ulcer and stomachache Thisplant has been in use for a long period of time withoutany documented serious adverse effects Studies carriedout in the past and present indicate that fennel possessesdiverse health benefits and are an important constituentof food Studies have shown that various extracts offennel possess a range of pharmacological actions such asantiaging antiallergic anticolitic antihirsutism anti-inflam-matory antimicrobial and antiviral antimutagenic antino-ciceptive antipyretic antispasmodic antistress antithromb-otic anxiolytic apoptotic cardiovascular chemomodulatoryaction cytoprotection and antitumor cytotoxicity diureticestrogenic properties expectorant galactogenic gastrointes-tinal effect hepatoprotective human liver cytochrome P4503A4 inhibitory hypoglycemic hypolipidemic memory-en-hancing property nootropic and oculohypotensive activity

supporting its traditional use However the most prominentand the well studied effects are the antimicrobial andantioxidant effects of essential oil of fennel in differentexperimental models The observed health benefits may becredited to the presence of the various phytochemicals likevolatile compounds flavonoids phenolic compounds fattyacids and amino acids

Fennel also contains mineral and trace elements likealuminum barium calcium cadmium cobalt chromiumcopper ironmagnesiummanganese nickel lead strontiumand zinc [124] fat soluble vitamins such as vitamins A Eand K water soluble vitamins like ascorbic acid thiamineriboflavin niacin and pyridoxine essential amino acidslike leucine isoleucine phenylalanine and tryptophane maycontribute to the myriad health beneficial effects at least inpart

Most of the pharmacological studies were conductedusing uncharacterized crude extracts of fennel It is difficultto reproduce the results of these studies and pinpoint thebioactive compounds Hence there is a need for chemi-cal standardization and bioactivity-guided identification ofbioactive compounds Among several classes of chemicalconstituents identified in fennel volatile components of fen-nel essential oil and phenolic compounds are assumed to bethe main bioactive compounds responsible for the majorityof its pharmacological effects However the vast traditionaluse and proven pharmacological activities of fennel indicatethat an immense scope still exists for its chemical explorationFuture studies should be focused on validating the mecha-nism of action responsible for the various beneficial effectsand also on understanding which plant based compounds areresponsible for the reported effectsThe required informationwhen available will enhance our knowledge and appreciationfor the use of fennel in our daily diet Also the outcomeof such chemical studies may further expand its existingtherapeutic potential

Thus there are many areas of research related to thisplant that need to be further explored to fully recognize itsbeneficial effects for society Factors such as geographical andseasonal variation play an important role in the authentica-tion of the chemical constituents responsible for the activitywhich also can be an area of interest Thus it is incumbenton researchers to fill the huge gap of insufficient knowledgeand create awareness among pharmacologists as well as inves-tigators towards providing better medicinal value derivedfrom this plant This can be fulfilled only by generatinginterest among the research community through writing ofcritical appraisals (paper) and extending the interdisciplinaryresearch area to focused studies on Foeniculum vulgare

32 Flavonoids Flavonoids are generally considered as animportant category of antioxidants in the human dietFlavonoids are abundant in the plants of Apiaceae family Ithas been reported that the presence of flavonol glycosidesin fennel species is related to its morphological hetero-geneity and variation Total flavonoid content of hydroal-coholic extracts is about 123 plusmn 018mgg Flavonoids likeeriodictyol-7-rutinoside quercetin-3-rutinoside and ros-marinic acid have been isolated from F vulgare [65]Amongst the flavonoids present in F vulgare the most preva-lent are quercetin-3-glucuronide isoquercitrin quercetin-3-arabinoside kaempferol-3-glucuronide and kaempferol-3-arabinoside and isorhamnetin glucoside [66] Quercetin-3-O-galactoside kaempferol-3-O-rutinoside and kaempferol-3-O-glucoside have also been reported to occur in the aque-ous extract of F vulgare [67] The flavonoids like isorham-netin 3-O-120572-rhamnoside quercetin and kaempferol werealso isolated from the ethyl acetate extract whereas quercetin3-O-rutinoside kaempferol 3-O-rutinoside and quercetin3-O-120573-glucoside were isolated from the methanol extractThese flavonoids exhibit remarkable antinociceptive and anti-inflammatory activity [68] Further quercetin rutin andisoquercitrin were reported to have the immunomodulatoryactivities [69]

33 Phenolic Compounds There has been a growing interestin phenolic components of fruits and vegetables which maypromote human health or lower the risk of disease Aqueous

extract of fennel fruits are rich in phenolic compoundsMany of them have antioxidant activities and hepatopro-tective properties The phenolic compounds present in Fvulgare are considered to be associated with the preventionof diseases possibly induced by oxidative stress such ascardiovascular diseases cancer and inflammation Thesephenolic compounds have received tremendous attentionamong nutritionists food scientists and consumers dueto their role in human health Fennel has been reportedto contain hydroxyl cinnamic acid derivatives flavonoidglycosides and flavonoid aglycones [67] The methanolicextract of fennel seeds contains rosmarinic acid chlorogenicacids as major phenolic compounds (149 and 68 resp)and quercetin and apigenin as themajor flavonoids (171 and125 resp) Also the total phenolic compounds in fennelmethanol extract were higher than the flavonoid compounds[23] F vulgare has been reported to contain phenolic acidslike 3-O-caffeoylquinic acid 4-O-caffeoylquinic acid 5-O-caffeoylquinic acid 13-O-di-caffeoylquinic acid 14-O-di-caffeoylquinic acid and 15-O-di-caffeoylquinic acid [65]Two compounds A and B were isolated and character-ized for the first time from the wild fennel and identi-fied as 34-dihydroxyphenethylalchohol-6-O-caffeoyl-120573-D-glucopyranoside and 3101584081015840-binaringenin respectively Thetotal phenolic and flavonoid contents ofwild fennel (24 and12 resp) were less as compared to cultivated fennel (31and 16 resp) [70]

4 Pharmacological Activities

Foeniculum vulgare is officially noted in Ayurvedic Pharma-copoeia as an important part of polyherbal formulations inthe treatment of different diseases and disorders A numberof biological-pharmacological studies have been undertakento evaluate the indigenous uses of F vulgare Few extracts of Fvulgare and isolated compounds have been evaluated for sev-eral activities namely antiaging antiallergic anticolitic anti-hirsutism anti-inflammatory antimicrobial and antiviralantimutagenic antinociceptive antipyretic antispasmodic

methanolic fruit extract of F vulgare inhibited the growthof Staphylococcus aureus and Bacillus pumilus with 1127 and1267mm zone of inhibition respectively [7]

Several studies indicating the antifungal effect of Fvulgare along with antibacterial effect are also reported inthe literature Martins et al [94] investigated the antibacterialand antifungal effects of three essential oils of Portugueseplants namely Foeniculum vulgareMentha spicata and Ros-marinus officinalis against Staphylococcus aureus Escherichiacoli Klebsiella pneumonia Pseudomona aeruginosa Staphy-lococcus epidermidis Candida albicans and phytopathogenic

diseases [97] In an in vitro study aqueous and alcoholicseed extracts of F vulgare exhibited inhibitory effect againstAlternaria alternata Mucor rouxii and Aspergillus flavus[98] Interestingly aqueous seed extract of F vulgare showedstrongest antifungal activity as compared to reference fungi-cidal agent that is griseofulvin [99]

All of the above mentioned studies were carried outon the crude extracts and it is difficult to pinpoint theactive antimicrobial metabolite A phenylpropanoid deriva-tive called dillapional characterized from F vulgare stem wasfound to be an antimicrobial constituent with MIC values of125 250 and 125 against Bacillus subtilis Aspergillus nigerand Cladosporium cladosporioides respectively A coumarinderivative scopoletin was also isolated as a marginallyantimicrobial agent [100] The characterization of sevendifferent types of oxygenatedmonoterpenes frommethylene

chloride crude extract of F vulgare [101] suggested thatthe crude extract containing monoterpenes could be a newmedicinal resource for antibacterial agents

A total of 78 compounds were identified from theactive antimycobacterial fraction of F vulgare with thehelp of gas chromatography-mass spectra (GC-MS) Outof these twenty compounds were tested against one sensi-tive and three MDR strains of Mycobacterium tuberculosisusing the Alamar Blue microassay Compounds that showedsome degree of antimycobacterial activity against all strainstested were the following linoleic acid (MIC 100 120583gmL)oleic acid (MIC 100 120583gmL) 13-benzenediol (MIC 100ndash200120583gmL) undecanal (MIC 50ndash200120583gmL) and 24-undecadienal (MIC 25ndash50120583gmL) 24-Undecadienal wasthe most active compound against multidrug resistant Mtuberculosis speciesThus the dietary intake of F vulgaremaylower the risk ofM tuberculosis infection [63]

Orhan et al [5] studied the antiviral activity of theessential oil of fruit sample of F vulgare along with 12other Turkish medicinal plants against the DNA virusHerpessimplex type-1 (HSV-1) and the RNA virus parainfluenzatype-3 (PI-3) Most of the oils and compounds displayedstrong antiviral effects against HSV-1 ranging between 08and 0025 120583gmL However the samples tested were lesseffective against PI-3 with results ranging between 16 and02 120583gmL Only the essential oils of Anethum graveolensFoeniculum vulgare (fully mature) Mentha piperita Menthaspicata Ocimum minutiflorum Ocimum vulgaris and Sat-ureja cuneifolia inhibited this virus significantly

All these literature findings validated the traditional usesof Foeniculum vulgare in infectious disorders like abdomi-nal pains antiemetic arthritis conjunctivitis constipationdepurative diarrhea dieresis fever flatulence gastralgia gas-tritis insomnia irritable colon mouth ulcer stomachacherespiratory disorders skin diseases and so forth There isalways a need for new antimicrobial agents due to rapiddevelopment of resistance Bioactive metabolites of F vulgaremay be a potential source for new antimicrobial agents

42 Anti-Inflammatory Activity Oral administration ofmethanol extract of F vulgare fruit to rat and mice exhibitedinhibitory effects against acute and subacute inflammatorydiseases The anti-inflammatory activity of methanol extractwas evaluated by using three screening protocols namelycarrageenan-induced paw edema arachidonic acid-inducedear edema and formaldehyde-induced arthritis Theseare widely used for testing nonsteroidal anti-inflammatorydrugs For acute inflammationmethanol extract (200mgkg)exhibits significant inhibition of paw edema (69) inducedby carrageenan injection as compared to the control groupof animals Methanol extract of F vulgare also inhibitsear-edema (70) induced by arachidonic acid in mice Thelevel of serum transaminase aspartate aminotransferase(AST) and alanine aminotransferase (ALT) significantlyincreases in the presence of methanolic extract of F vulgareon inflammation induced by formaldehyde as comparedto control group The assessment of the level of AST and

ALT provides a good and simple tool to measure the anti-inflammatory activity of the target compounds [102] Theseoverall results seem to suggest that F vulgare FME mayact on both the cyclooxygenase and lipoxygenase pathways[79]

43 Antiallergic Activity Methanolic extract of F vulgarefruit showed significant inhibitory effect on DNFB- (24-dinitrofluorobenzene-) induced delayed type hypersensitiv-ity after oral administration of 200mgkg once a day for7 days The inhibitory effect on immunologically inducedswelling suggests the possible immunosuppressive propertiesof F vulgare [79]

44 Hepatoprotective Activity Essential oil of F vulgareseeds revealed a potent hepatoprotective effect against acutehepatotoxicity produced by carbon tetrachloride in ratsOral administration of F vulgare essential oil decreases thelevels of serum aspartate aminotransferase (AST) alanineaminotransferase (ALT) alkaline phosphatase (ALP) andbilirubin as compared to the control group Ozbek et alsuggest that the constituents (d-limonene and 120573-myrcene) ofessential oil may have played a key role in the protection ofliver from CCl

4toxicity [9]

45 Anxiolytic Activity Anxiety is the unpleasant feeling offear and concern When anxiety becomes excessive it maybe considered as an anxiety disorder Anxiolytic fennel isa drug used for the treatment of anxiety and its relatedpsychological and physical symptoms Naga Kishore et al[89] investigated the anxiolytic activity of ethanolic extract ofF vulgare fruit with the help of elevated plus maze rota rodopen field test and whole board models The 100 to 200mgdose of extract per kg of body weight of animal revealedsignificant activity when compared to reference anxiolyticdrug called diazepam (1mgkg) Thus fennel extract maypossess anxiolytic activity supporting its traditional claimabout anxiolytic activity reported in 19th edition of Pharma-cology and Pharmacotherapeutics by Sathodkar Bhandarkarand Rege

46 Antistress Activity Drug and food of natural originplay a significant role in public healthcare systems and arebeing investigated as remedies for a number of stress-relateddisorders [103]Thewhole plant extract of F vulgare exhibitednotable antistress effect against stress induced by forcefulswimming of test animals The key parameters that isurinary levels of vanillyl mandelic acid (VMA) and ascorbicacid in rats were used to evaluate antistress activity Theplant extract (50 100 and 200mgkg body weight) showeda significant improvement in urinary levels of VMA (119875 lt0001) and ascorbic acid excretion levels (119875 lt 0001) in testanimals when compared to the normal basal levels in controlgroup of animalsThus the extract of entire plant of F vulgareacts as an antistress agent [13]

47 Memory-Enhancing Property There are a number ofplants whose consumption is believed to enhance memory

22 BioMed Research International

and intelligence These were usually given to children as partof their food F vulgaris an ayurvedic rasayana (mixture)possessing multiple neuropharmacological activities Theantidepressant activity of fennel has been well documentedin ethnomedicine The whole plants extract (50 100 and200mgkg) of F vulgare exhibited memory-enhancing effectagainst scopolamine-induced amnesic rats This experimentwas evaluated by conditioned avoidance response (CAR)technique The CAR of rats administered with the extractincreased gradually to 95 over 7 to 12 days The acquisition(time to achieve 95 CAR) for rats administered with theextract was dose- and time-dependent compared to controlgroup which took 12 days for acquisition The percentavoidance was always higher in the extract-treated groupsas compared to control group Animals receiving 200mgkgbody weight of the extract took ten days while groups treatedwith 100 and 50mgkg doses of the extract required elevenand twelve days respectively to reach the point of acquisitionAdministration of scopolamine produced amnesia as seenfrom reduction in the observed CAR Amnesia was greaterin the control group than in extract-treated groups How-ever continued treatment with F vulgare produced betterretention and recovery in a dose-dependent manner thanthe vehicle-treated animals Recovery from scopolamine-induced amnesia in the extract-treated groups took 3ndash5 dayswhen compared to normal (control) group which took over6 days This overall progress suggests that F vulgare extractpossesses memory-enhancing property [13]

48 Nootropic Activity Alzheimerrsquos disease is a neurode-generative disorder associated with a decline in cognitiveabilities Dementia is one of the age-related mental problemsand a characteristic symptom of Alzheimerrsquos disease Thereis some evidence in favor of use of F vulgare for the treat-ment of cognitive disorders like dementia and Alzheimerrsquosdisease Methanol extract of the whole plant of F vul-gare administered for eight successive days ameliorated theamnesic effect of scopolamine and aging-induced memorydeficits inmiceThis extract increased step-down latency andacetylcholinesterase inhibition in mice significantly Thus Fvulgaremay be employed in treatment of cognitive disorderssuch as dementia and Alzheimerrsquos disease as a nootropic andanticholinesterase agent [80]

49 Antihirsutism Activity Idiopathic hirsutism is definedas the occurrence of excessive male pattern hair growth inwomen who have a normal ovulatory menstrual cycle andnormal levels of serum androgens It may be a disorder ofperipheral androgen metabolism Traditionally Foeniculumvulgare has been used as an estrogenic agent It has beenreputed to increase milk secretion promote menstruationfacilitate birth and increase libido On considering aboveaspect Javidnia and his research team evaluated the antihir-sutism activity of ethanolic extract of F vulgare seed againstidiopathic hirsutism by preparing cream containing 1 and 2of fennel extract The efficacy of treatment with the creamcontaining 2 fennel is better than the cream containing 1fennel and these two were more potent than placebo (control

group) The mean values of hair diameter reduction were78 183 and minus05 for patients receiving the creamscontaining 1 2 and 0 (placebo) respectively [78]

410 Estrogenic Properties Since the discovery of the estrusinducing effects of some plant products in 1926 consider-able effort has been devoted towards the characterizationof phytoestrogens including flavonoids isoflavonoids chal-cones coumestans stilbenes lignans saponins and essentialoils [16] F vulgare has estrogen-like activity In male ratstotal concentration of protein was found to be significantlydecreased in testes and in vasa deferentia whereas increasedin seminal vesicles and in prostate gland On the otherhand simultaneous decrease in the activities of acid andalkaline phosphatase in all these regions (except that alka-line phosphatase was unchanged in vasa) due to the oraladministration of acetone extract of F vulgare fruit wasobserved In female rats oral administration of the extract for10 days led to vaginal cornification and oestrus cycle [8] Totalconcentration of nucleic acids and protein as well as the organweights increased in both the tissues namely mammaryglands and oviducts due to the oral administration of acetoneextract (50 150 and 250120583g100 g body wt) of F vulgare seeds[104] Fennel oil was reported to exhibit estrogenic activitypromote menstruation and alleviate the symptoms of femaleclimacteric and increase libido [71] Administration of fenneloil (25 and 50 120583gmL final concentration in the organ bath)failed to exhibit any remarkable effect in uterine contrac-tion While 10 20 and 40 120583gml concentration of fennel oilrevealed significant inhibitory effect against prostaglandinE2 Fennel oil significantly reduces the frequency of uterinecontraction induced by prostaglandin E2 Thus the extractsof F vulgare have strong estrogenic activity [76]

411 Galactogenic Activity Foeniculum vulgare has been usedformillennia to increasemilk secretion [105]Thus F vulgarebelongs to galactagogue substance Structural similarity ofits main constituent anethole to dopamine seems to beresponsible for galactogenic activityDopamine acts to inhibitthe secretion of the milk-producing hormone prolactinAnethole might influence milk secretion by competing withdopamine at the appropriate receptor sites thereby inhibitingthe antisecretory action of dopamine on prolactin [71] It wasreported that anol (demethylated anethole) causes growthof the lobule-alveolar system in the mammary glands ofimmature female rabbits and induces menstruation in miceand other experimental animals Anol also gave positiveresults in the Jadassohn nipple test a test which involvesthe measurement of changes induced in the nipples ofguinea pigs subjected to the cutaneous application of sexhormones However further research suggests that the actualpharmacologically active agents responsible for galactogenicactivity are polymers of anethole such as dianethole andphotoanethole rather than anol or anethole itself [20 76]

412 Expectorant Activity F vulgare seeds stimulate theciliary motility of the respiratory apparatus and enhance the

BioMed Research International 23

external transport of extraneous corpuscles This action sug-gests a use for fennel in treating bronchial and bronchopul-monary afflictions and in particularly polluted environments[106] The volatile oil of F vulgare stimulates the contractionof the smooth muscles of the trachea an action that couldfacilitate the expectoration of mucus bacteria and othercorpuscles extraneous to the respiratory tracts [74]

413 Anticolitic Activity Essential oil of fennel regulates themotility of smooth muscles of the intestine while at thesame time reducing intestinal gas Alone or combined withother plant medicinals Foeniculum vulgare is indicated in thetreatment of spastic gastrointestinal disturbances in someforms of chronic colitis (which resist other treatments) indyspepsias from gastrointestinal atony in dyspepsias withthe sensation of heaviness in the stomach and so forthTheaddition of fennel to preparations containing anthraquinoniccomponents reduces the occurrence of abdominal pain oftenassociated with this type of laxative [73]

414 Antinociceptive Activity Antinociceptive means anysubstance that inhibits nociception which is a physiologicalprocess underlying the sensation of pain Briefly it reducesthe sensitivity to painful stimuli The various extracts ofaerial part of F vulgare namely hexane methylene chlorideethyl acetate and methanolic extract showed remarkableantinociceptive activity against acetic acid induced writhingin mice [68] The methanolic extract of the aerial parts ofF vulgare exhibited the highest antinociceptive activity at adose level of 2000mgkg while the activity exhibited by theethyl acetate extract was at dose level 800mgkgOn the otherhand n-hexane extract (700mgkg) and methylene chlorideextract (500mgkg) exhibited similar antinociceptive activi-ties being less than peripheral antinociceptive reference drug(acetyl salicylic acid) [68]

415 Diuretic Activity A diuretic is any substance thatpromotes the production of urine Briefly it is an agentthat promotes diuresis Diuretics work by promoting theexpulsion of urine (measured as the urine volume [UV]excreted) and urinary sodium (UNa) from the body and thishelps reduce the volume of blood circulating through thecardiovascular system Caceres et al [107] performed a studyin conscious animals and administered a powdered extractof the whole plant (F vulgare) which had no effect on UVor UNa The ethanolic extract of F vulgare fruit revealedexcellent diuretic activity and proves the earlier folk claimof F vulgare which was reported in the United State ofAmerica (Table 5) The fruit extract showed statistically ahighly significant diuretic effect F vulgare induced diuresis(500mgkg dose)was comparable to that of reference diureticagent urea (960mgkg dose) in mice with a urine outputthat was almost double that of the control group Thediuresis was not associated with changes in sodium andorpotassium excretion [108] In another part of the study theauthors showed that Foeniculum vulgare had little effect onthe noradrenalin contractile responses of aortic rings thus

suggesting that it worked mainly as a diuretic and natriureticwith little effect on arterial vascular tone [77]

416 Cardiovascular Activity An aqueous extract of F vul-gare leaves possesses potential cardiovascular action Thiseffect was investigated using pentobarbital-anaesthetisedmale albino Sprague-Dawley rats [75] An intravenousadministration of the lyophilized boiled water extract ofleaves produced a significant dose-related reduction in arte-rial blood pressure without affecting the heart rate or respi-ratory rate On the other hand the nonboiled aqueous extractshowed very little hypotensive activityThe hypotensive effectof the boiling water extract appeared not to be mediated viaadrenergicmuscarinic ganglionic or serotonergic receptorshowever histamine antagonists inhibited the hypotensiveeffect in a dose-related manner [75]

417 Oculohypotensive Activity The aqueous seed extract ofF vulgare demonstrated significant oculohypotensive activityusing water loading and steroid induced glaucoma modelThis extract exhibited 1749 2116 and 2203 reduction ofintraocular pressure in normotensive rabbits at 03 06and 12 (wv) concentrations respectively A maximummean difference of 3120 was observed between vehiclestreated and extracts treated eyes in water loading experi-mental animal model while a maximum mean intraocularpressure lowering of 3129 was observed in steroid inducedmodel of glaucoma Thus the aqueous extract of F vulgarerevealed oculohypotensive activity which was found to be asgood as that of reference standard antiglaucoma drugs calledtimolol [84]

418 Antithrombotic Activity Tognolini et al [55] providedevidence of potent inhibitory activity of essential oil of F vul-gare against platelet aggregation induced byADP arachidonicacid and collagen in guinea pig plasma Similar findingswere reported by Yoshioka and Tamada [109] for aggregationof rabbit platelets by an aromatic factor of fennel oil Theessential oil and anethole (a constituent of oil) of F vulgaretested in vitro in rat aorta with or without endotheliumdisplayed comparable NO-independent vasorelaxant activityat antiplatelet concentrations It supports the safety of Fvulgare that is free from cytotoxic effects Anethole and Fvulgare did not cause cytotoxicity when incubated for 30minupto 300 120583gmL in platelet viability test This concentrationwas largely compatible with those adopted in the functionalin vitro tests In vivo both F vulgare essential oil andanethole orally administered in a subacute treatment to mice(30mgkgday for 5 days) showed significant antithrom-botic activity preventing the paralysis induced by collagen-epinephrine intravenous injection (70 and 83 protectionresp)Thus essential oil and its main component anethole ofF vulgare showed a safe antithrombotic activity in guinea pigplasma that seems due to their broad spectrum antiplateletactivity clot destabilizing effect and vasorelaxant action [55]

419 Antimutagenic Effect Essential oil of F vulgare revealednoteworthy protective effects against genotoxicity in mice

induced by cyclophosphamide Genotoxicity and cytotoxicitywere assessed by using mice bone marrow chromosomalaberration micronucleus and sperm abnormality assaysrespectively Oral administration of essential oil (1 and2mLkg) significantly inhibited the frequencies of aberrantmetaphases chromosomal aberrations micronuclei forma-tion and cytotoxicity in mouse bone marrow cells inducedby cyclophosphamide and also produced a significant reduc-tion of abnormal sperm and antagonized the reduction ofcyclophosphamide induced superoxide dismutase catalaseand glutathione activities and inhibited increased malondi-aldehyde content in the liver Additionally F vulgare inhibitsthe oxidative stress induced by cyclophosphamide [90]

420 Gastrointestinal Effect Theaqueous extract of F vulgareshowed remarkable antiulcerogenic effect against ethanol-induced gastric lesions in rats It was found that pretreatmentwith aqueous extract significantly reduced ethanol-inducedgastric damageThis effect of aqueous extract was highest andstatistically significant in 300mgkg group comparedwith thecontrol (119875 lt 0001) group of animal Additionally aqueousextract of F vulgare significantly reduced the whole bloodmalondialdehyde levels while significantly increased nitritenitrate ascorbic acid retinol and beta-carotene levels Thusaqueous extract of F vulgare fruit had clearly a protectiveeffect against ethanol-induced gastric mucosal lesion in rats[81]

421 Chemomodulatory Action The chemopreventive effectof different doses of test diet of Foeniculum vulgare seeds wasexamined against 712-dimethylbenz(a)anthracene- (DMBA-) induced skin papillomagenesis and benzo(a)pyrene-[B(a)P-] induced forestomach papillomagenesis at the peri-initiational level in Swiss albino mice Fennel seeds exhibita significant reduction in the skin and the fore-stomachtumor incidence and tumor multiplicity as compared tothe control group Further biochemical assays showeda significant increase in the contentactivities of phase Ienzymes especially in the case of 6 test diet A concomitantincrease in the activities of the phase II enzymes wasobserved with all the doses of test diet under study Asignificant enhancement in the activities of antioxidantenzymes was observed especially at 4 and 6 test diets offennel These findings were indicative of chemopreventivepotential of fennel against carcinogenesis This is the firstreport showing chemopreventive potential of seeds of fennelagainst carcinogenesis [85]

422 Cytoprotection and Antitumor Activity Anethole is theprincipal active component of fennel seeds which has exhib-ited anticancer activity Al-Harbi et al studied the antitumoractivity of anethole against Ehrlich ascites carcinoma inducedin a tumor model in Swiss albino mice The study revealedthat anethole increased survival time reduced tumor weightand reduced the volume and body weight of the Ehrlichascites tumour-bearing mice It also produced a significantcytotoxic effect in the Ehrlich ascites tumour cells in the pawreduced the levels of nucleic acids and malondialdehyde and

increased glutathione concentrations [110] In vitro cytopro-tection activity of methanolic extract of Foeniculum vulgarewas evaluated against normal human blood lymphocytes bymicronucleus assay and antitumor activity against B16F10melanoma cell line by Trypan blue exclusion assay for cellviability Lymphocyte culture treated with 70 methanolicextract of Foeniculum vulgare showed very less percentage ofmicronucleus that is 0006 as compared to standard drugdoxorubicin which showed 0018 micronucleus On theother hand 70methanolic extract of Foeniculum vulgare haspotent antitumor activity at the concentration of 200120583gmLThe results suggest that the Foeniculum vulgare could beconsidered as a natural resource of antitumor agents as wellas cytoprotective to normal cells [11]

423 Cytotoxicity Kaileh and his coworker investigated thecytotoxic effect of organic extracts of 24 selected Palestinianmedicinal plant species The plant selection was based onexisting ethnobotanic information and interviews with localhealers The extracts of the plants under investigation weretested for their potential antitumor (cytotoxic) effect on themurine fibrosarcoma L929sA cells and on the human breastcancer cells MDA-MB231 and MCF7 The extract from Fvulgare presented an IC (50) value at 24 h of 700 plusmn 28 and500plusmn17 120583gmL on L929sA andMCF7 cells respectivelyThenuclear transcription factor NFkappaB or NF120581B regulatesthe expression of various genes They further investigatedthe effect of nine promising plant extracts withheld fromthe first cell viability screening on NF120581B activation Thedichloromethane and methanol (1 1) extract of aerial part ofF vulgare revealed immunomodulatory NF120581B activities [82]Also Berrington and Lall investigated the in vitro cytotoxicityof acetone extracts of F vulgare and other eight medicinalplants against a noncancerous African green monkey kidney(Vero) cell line and an adenocarcinoma cervical cancer(HeLa) cell line [87]

424 Antipyretic Activity F vulgare extract showedantipyretic activity against hyperpyrexia in mice It wasinduced by SC administration of 2mL100 g of a 20aqueous suspension of brewerrsquos yeast As an antipyreticagent ethanolic extract of F vulgare fruit showed a moderateantipyretic activity that was statistically significant after 30and 90min (119875 lt 001) [108]

425 Hypolipidemic Activity The aqueous extract of F vul-gare revealed notable hypolipidemic and antiatherogenicactivity against Triton WR-1339 induced hyperlipidemiain mice Aqueous extract causes significant reduction ofplasma lipid levels that is cholesterol triglycerides LDL-cholesterol and apolipoprotein-B decreased by 40 2361 and 61 respectively and increase in HDL-cholesteroland apolipoprotein A1 by 85 and 58 respectively [88]

426 Hypoglycemic Activity The essential oil of F vulgareexhibits potential hypoglycemic and antioxidant activityagainst streptozotocin induced diabetes in rats Essentialoil (30mgkg body weight) of F vulgare works in the

427 Antispasmodic Activity The antispasmodic activity of25 and 100mLL of alcoholic extract of Foeniculum vulgarealong with other Germanic medicinal plants namelyMelissaofficinalis Rosmarinus officinalisMentha piperitaMatricariachamomilla Carum carvi and Citrus aurantium were testedemploying the guinea pig ileum and using acetylcholine andhistamine as spasmogens An alcoholic extract of the fruits ofFoeniculum vulgare possesses antispasmodic activity whichinhibits the acetylcholine and histamine-induced guineapig ileal contractions in vitro An essential oil which isobtained from the fruits of Foeniculum vulgare 25 120583gmL and10 120583gmL respectively inhibited oxytocin and prostaglandin[72]

428 Apoptotic Activity The apoptotic activities of ethanolextracts from fruits of seven species of Apiaceae familynamely Eryngium planum Archangelica officinalis Pasti-naca sativa Heracleum sibiricum Carum carvi Foenicu-lum vulgare and Levisticum officinale against ML-1mdashhumanacute myeloblastic leukaemia J-4501mdashhuman acute Tcell leukaemia EOLmdashhuman eosinophilic leukaemia HL-60mdashhuman Caucasian promyelocytic leukaemia 1301mdashhuman T cell leukaemia lymphoblast C-8166mdashhuman Tcell leukaemia U-266B1mdashhuman myeloma WICLmdashhumanCaucasian normal B cell and H-9mdashhuman T cell wereinvestigated with the help of Trypan blue assay and AnnexinV fluos assay [86] The ethanol extract from fruit F vulgareshowed the highest mortality in Trypan blue test for J45cell linemdash4 of viable cells and for C8166 cell linemdash100of mortality However the cells of other lines showed thehighest viability HL60mdash60 EOLmdash48 and MLmdash1ndash42The normal cell line H9 and WICL showed 35 and 25of viable cells respectively C8166 cell line and J-45 cell lineshowed the highest level of the apoptotic cells detected byAnnexin V methodmdash100 and 93 respectively Howeverthe cells of two lines HL60 and EOL-1 showed the lowerlevels of apoptotic cellsmdash52 and 60 respectively Highpercentage of apoptotic cells was observed inH9 andWICLmdash76 and 93 respectively [86]

429 Human Liver Cytochrome P450 3A4 Inhibitory ActivityThirteen compounds isolated from the methanolic extract offennel have been found to possess human liver cytochromeP450 3A4 inhibitory activity Among these compounds 5-methoxypsoralen (5-MoP) showed the strongest inhibitionwith an IC50 value of 183120583m and with a mixed type ofinhibition [83]

430 Antiaging Effects Rasul and his coworker developeda base and formulation containing 4 concentrated seedextract of F vulgare This formulation shows notable antiag-ing effect with supporting experimental data related to skinmoisture and transepidermal water loss (TEWL) The basewas insignificant while the formulation showed significanteffects on skin moisture and TEWL The texture parameterenergy showed a significant increase proving that the formu-lation possesses potential antiaging effects [50]

431 Bronchodilatory Effect Ethanol extract and essential oilfrom F vulgare exhibited bronchodilatory activity on con-tracted tracheal chains of guinea pig The potassium channelopening effect of fennel may contribute on its relaxant effecton guinea pig tracheal chains [111] Moreover anethole bearsa striking resemblance to the catecholamines epinephrinenorepinephrine and dopamine This structural similarityappears to be responsible for the various sympathomimeticactivities of F vulgare such as bronchodilatory effect [71]

432 Antioxidant Activities Naturally occurring antioxi-dants can be used to protect human beings from oxidativestress damage [112] Fennel was known as excellent source ofnatural antioxidants and contributed to the daily antioxidantdiet [113]Wild fennel was found to exhibit a free radical scav-enging activity with higher content phenolic and flavonoidthan medicinal and edible fennel and the aerial parts ofthe Italian fennel populations showed the highest DPPHscavenging activity [65] Phenolic compounds of fennelincluding caffeoylquinic acid rosmarinic acid eriodictyol-7-orutinoside quercetin-3-O-galactoside and kaempferol-3-O-glucoside showed antioxidant activities [67] The volatileoil showed strong antioxidant activity in comparison withbutyrated hydroxyanisole and butylated hydroxytolueneEthanol and water extracts of fennel showed less antioxidantactivity compared with essential oil [114]

5 Environmental Application

Foeniculum vulgare that is fennel not only exhibited phar-macological activities but also revealed a few environmentalactivities These activities play a key role in the managementof nematode insect mosquitoes and some harmful larvae ofmalaria producing vector Thus the extracts of F vulgare andisolated biologically active compounds have been evaluatedfor their insecticidal repellent acaricidal larvicidal andnematicidal activity [115ndash119] A brief review on the differenttype of ecofriendly environmental activities as reported onthis plant is summarized below

51 Insecticidal Activities The fruit derived phytoconstitu-ents of F vulgare exhibited prominent insecticidal activi-ties against Sitophilus oryzae Callosobruchus chinensis andLasioderma serricorne This activity was examined usingdirect contact application and fumigation methods Thebiologically active constituents that is phenylpropenes (E)-anethole and estragole and the monoterpene (+)-fenchonewere characterized from Foeniculum fruit By using a filter

26 BioMed Research International

paper diffusion test estragole (0168mg cmminus2) caused 91mortality to S oryzae within 1 day after treatment whereas(+)-fenchone and (E)-anethole gave over 90 mortality at 2and 4 day after treatment respectively

After 2 days of treatment all test compounds (0021mg cmminus2 concentration) revealed potent insecticidal activityagainst C chinensis Whereas after 1 day of treatment (E)-anethole (0105mg cmminus2) gave 100mortality of L serricornewhereas 90 and 60 mortality at 4 day after treatment wasachieved with estragole and (+)-fenchone respectively In afumigation test the compounds were much more effectiveagainst adults of S oryzae C chinensis and L serricorne inclosed cups than in open ones indicating that the insecticidalactivity of test compounds was largely attributable to fumi-gant action As naturally occurring insect-control agents theF vulgare fruit-derived materials described could be usefulfor managing field populations of S oryzae C chinensis andL serricorne [116]

52 Acaricidal Activity Fennel oil shows significant acaricid-al activity againstDermatophagoides farinae andDermatoph-agoides pteronyssinus (+)-fenchone and p-anisaldehyde aremajor constituents of fruit oil of F vulgare P-anisaldehydewas the most toxic compound against D farinae and is muchmore effective compared with benzyl benzoate thymol andestragol [118]

53 Repellent Activity The methanolic extract of fruits ofF vulgare was spectroscopically characterized for the pres-ence of biologically active constituents called (+)-fenchoneand (E)-9-octadecenoic acid The repellent activity of theseconstituents was tested against hungry Aedes aegypti femaleswith the help of skin and patch tests and compared withthat of the commercial repellent agent called NN-diethyl-m-toluamide (DEET) and (Z)-9-octadecenoic acid In askin test with female mosquitoes (+)-fenchone and (Z)-9-octadecenoic acid (04mgcm2) exhibitedmoderate repellentactivity at 30min after treatment whereas DEET providedgt1 h of protection against adult mosquitoes at (02mgcm2)Thus (+)-Fenchone and (E)-9-octadecenoic acid are poten-tial mosquito repellent agents or lead compounds [117]

54 Larvicidal Activity Plant extracts and oils may act asalternatives to conventional pesticides for malaria vectorcontrol By considering this aspect Sedaghat et al [119] inves-tigated the larvicidal activity of essential oils of three plantsof Apiaceae family against malaria vector called Anophe-les stephensi The larvicidal activity was evaluated againstlaboratory-reared larvae by standard method of WHO TheF vulgare oil was the most effective against A stephensiwith LC(50) and LC(90) values of 2010 and 4451 ppmrespectively [119] Additionally the essential oil extracts fromleaves flowers and roots of F vulgare exhibit noticeablelarvicidal activity against fourth-instar larvae of themosquitoCulex pipiens molestus Terpineol and 18-cineole content of Fvulgare are the most effective phytoconstituent against Culexpipiens molestus bites offering complete protection for 16 and2 h respectively [120] Recently Zoubiri et al [57] reported

the larvicidal activity of essential oil of fennel seed againstCulex pipiensmosquitoThus F vulgare can serve as a naturallarvicidal agent

55 Nematicidal Activity Oka et al investigated the in vitronematicidal activity of essential oils extracted from 27 spicesand aromatic plants in pot experiments Twelve of thetwenty-seven essential oils immobilized more than 80 ofjuveniles of the root-knot nematodeMeloidogyne javanica ata concentration of 1000 120583Lliter At this concentration mostof these oils also inhibited nematode hatching Essential oilsof Carum carvi Foeniculum vulgare Mentha rotundifoliaand Mentha spicata showed the highest nematicidal activityamong the in vitro tested oils In 3-liter pot experimentsnematicidal activity of the essential oils and their componentswas confirmed at 200 and 150mgkg respectivelyThe resultssuggest that the essential oils and theirmain componentsmayserve as nematicides [115]

The long history of ethnomedicinal application with noreports of any serious side effects suggests that F vulgarecould be considered as safe Inmost toxicity experiments car-ried out on F vulgare no sign of toxicity was observed Shahand his coworker in 1991 investigated the detailed toxicityaccount of ethanolic extract of fennel fruit in experimentalmice with respect to acute and 90 days longer term toxicity[121] In experimentation Shah and his coworker observedthe general symptoms of toxicity and mortality for only 24 hin acute toxicity Whereas in another part of toxicity theystudied the effect of fennel extract on mice with 90 dayslong term treatment Acute toxicity of ethanolic extract of Fvulgarewas assessed in 35mice by using three concentrationsnamely 05 1 and 3 gkg body weight In this investigation Fvulgare exhibited no signs of toxicity and no mortality wasobserved upto the dose level 3 gkg body weight In case oflonger term toxicity ethanolic extract of F vulgare (100mgkgbody weightday) was given in drinking water of animals(30 male and 30 female mice) All external morphologicalhaematological and spermatogenic changes in addition tobody and vital organ weights were recorded The extractcaused no significant chronic mortality as compared tocontrols during this investigation The treated male micegained significant weight during chronic treatment while aloss or no significant change in weight was noticed in thefemale mice treated with the same extract The extracts didnot show spermatotoxic effects Thus Shah and his coworkerconcluded that fennel extract is safe based on both acuteandor long term toxicity studies [121] Additionally the plantextract in doses of 05 1 and 3 gkg (orally) did not causeany deaths These doses do not show any type of toxicityagainst several parameters tested namely locomotor activitybizarre reactions sensitivity to sound social interaction tailposture aggressive behaviour ataxia paralysis convulsionstremors prostration exophthalmos pupil size defecationsalivation urination pattern of respiration nasal dischargecyanosis and piloerection Exceptionally only the 3 gkg dose

showed signs of reduced locomotor activity and piloerec-tion Otherwise all other parameters were negative [108]In another experiment of acute toxicity different solventextracts namely n-hexane methylene chloride ethyl acetateand methanol extracts of F vulgare upto 55 gkg concentra-tion did not revealed any kind of toxicity in mice LD50being 675 110 692 and 15 gkg for n-hexane methylenechloride ethyl acetate and methanol extracts respectively[68] The plant extract of F vulgare was administered orallyat a dose of 100 200 400 600 800 1000 and 2000mgkgof body weight of mice Each group of animals was undervisual observation for 10 days for the external behavior ofneurological toxicity created by plant extract Even the micereceiving highest dose of F vulgare extract did not show anymortality or toxicity demonstrating the safety profile of theplant extract [89]

The acute oral 50 LD50 for anethole in rats was foundto be 2090mgkg Repeated doses of one-third the LD50 ofanethole (695mgkg) given to rat caused mild liver lesionsIt would therefore appear that in normal therapeutic dosagesanethole would have minimal hepatotoxicity When anetholewas fed to rats daily for one year as 025 of the dietno hepatic damage was seen [122] The acute oral LD50 ofessential oil in rats is 1326mgkg [76] The use of F vulgareessential oil as a remedy for control of primary dysmenorrheaincreases concern about its potential teratogenicity due toits estrogen like activity Evaluation of teratogenicity ofessential oil using limb bud mesenchymal cells showed thatthe essential oil may have toxic effect on fetal cells butthere was no evidence of teratogenicity upto concentrationof 93mgmL of culture medium [123] The overall toxicitystudies carried out on F vulgare accounts for its safety at therecommended therapeutic doses

7 Conclusions

The available scientific research on Foeniculum vulgarehas shown that it is an important medicinal plant used ina wide range of ethnomedical treatments especially forabdominal pains antiemetic aperitif arthritis cancer colicin children conjunctivitis constipation depurative diarrheadieresis emmenagogue fever flatulence gastralgia gastritisinsomnia irritable colon kidney ailments as a laxativeleucorrhoea liver pain mouth ulcer and stomachache Thisplant has been in use for a long period of time withoutany documented serious adverse effects Studies carriedout in the past and present indicate that fennel possessesdiverse health benefits and are an important constituentof food Studies have shown that various extracts offennel possess a range of pharmacological actions such asantiaging antiallergic anticolitic antihirsutism anti-inflam-matory antimicrobial and antiviral antimutagenic antino-ciceptive antipyretic antispasmodic antistress antithromb-otic anxiolytic apoptotic cardiovascular chemomodulatoryaction cytoprotection and antitumor cytotoxicity diureticestrogenic properties expectorant galactogenic gastrointes-tinal effect hepatoprotective human liver cytochrome P4503A4 inhibitory hypoglycemic hypolipidemic memory-en-hancing property nootropic and oculohypotensive activity

supporting its traditional use However the most prominentand the well studied effects are the antimicrobial andantioxidant effects of essential oil of fennel in differentexperimental models The observed health benefits may becredited to the presence of the various phytochemicals likevolatile compounds flavonoids phenolic compounds fattyacids and amino acids

Fennel also contains mineral and trace elements likealuminum barium calcium cadmium cobalt chromiumcopper ironmagnesiummanganese nickel lead strontiumand zinc [124] fat soluble vitamins such as vitamins A Eand K water soluble vitamins like ascorbic acid thiamineriboflavin niacin and pyridoxine essential amino acidslike leucine isoleucine phenylalanine and tryptophane maycontribute to the myriad health beneficial effects at least inpart

Most of the pharmacological studies were conductedusing uncharacterized crude extracts of fennel It is difficultto reproduce the results of these studies and pinpoint thebioactive compounds Hence there is a need for chemi-cal standardization and bioactivity-guided identification ofbioactive compounds Among several classes of chemicalconstituents identified in fennel volatile components of fen-nel essential oil and phenolic compounds are assumed to bethe main bioactive compounds responsible for the majorityof its pharmacological effects However the vast traditionaluse and proven pharmacological activities of fennel indicatethat an immense scope still exists for its chemical explorationFuture studies should be focused on validating the mecha-nism of action responsible for the various beneficial effectsand also on understanding which plant based compounds areresponsible for the reported effectsThe required informationwhen available will enhance our knowledge and appreciationfor the use of fennel in our daily diet Also the outcomeof such chemical studies may further expand its existingtherapeutic potential

Thus there are many areas of research related to thisplant that need to be further explored to fully recognize itsbeneficial effects for society Factors such as geographical andseasonal variation play an important role in the authentica-tion of the chemical constituents responsible for the activitywhich also can be an area of interest Thus it is incumbenton researchers to fill the huge gap of insufficient knowledgeand create awareness among pharmacologists as well as inves-tigators towards providing better medicinal value derivedfrom this plant This can be fulfilled only by generatinginterest among the research community through writing ofcritical appraisals (paper) and extending the interdisciplinaryresearch area to focused studies on Foeniculum vulgare

Turkish [51 56] Serbian [52] Indian [54] and Chinese [53]fennels The hexane extracts of fennel were analyzed by GC-MS and 78 compounds were identified from these extractsthe major compounds were identified as 13-benzenediol 1-methoxycyclohexene o-cymene sorbic acid 2-hydroxy-3-methyl-2-cyclopenten-1-one estragole limonene-10-ol and3-methyl-2-cyclopenten-1-one [63] Diao et al [64] identifya total of 28 components by GC and GCMS from fenneloil representing 958 of the total amount Trans-Anethole(6853) a phenylpropanoid was found to be the maincomponent followed by estragole (1042) with limonene(624) fenchone (545) and others as minor components

32 Flavonoids Flavonoids are generally considered as animportant category of antioxidants in the human dietFlavonoids are abundant in the plants of Apiaceae family Ithas been reported that the presence of flavonol glycosidesin fennel species is related to its morphological hetero-geneity and variation Total flavonoid content of hydroal-coholic extracts is about 123 plusmn 018mgg Flavonoids likeeriodictyol-7-rutinoside quercetin-3-rutinoside and ros-marinic acid have been isolated from F vulgare [65]Amongst the flavonoids present in F vulgare the most preva-lent are quercetin-3-glucuronide isoquercitrin quercetin-3-arabinoside kaempferol-3-glucuronide and kaempferol-3-arabinoside and isorhamnetin glucoside [66] Quercetin-3-O-galactoside kaempferol-3-O-rutinoside and kaempferol-3-O-glucoside have also been reported to occur in the aque-ous extract of F vulgare [67] The flavonoids like isorham-netin 3-O-120572-rhamnoside quercetin and kaempferol werealso isolated from the ethyl acetate extract whereas quercetin3-O-rutinoside kaempferol 3-O-rutinoside and quercetin3-O-120573-glucoside were isolated from the methanol extractThese flavonoids exhibit remarkable antinociceptive and anti-inflammatory activity [68] Further quercetin rutin andisoquercitrin were reported to have the immunomodulatoryactivities [69]

33 Phenolic Compounds There has been a growing interestin phenolic components of fruits and vegetables which maypromote human health or lower the risk of disease Aqueous

extract of fennel fruits are rich in phenolic compoundsMany of them have antioxidant activities and hepatopro-tective properties The phenolic compounds present in Fvulgare are considered to be associated with the preventionof diseases possibly induced by oxidative stress such ascardiovascular diseases cancer and inflammation Thesephenolic compounds have received tremendous attentionamong nutritionists food scientists and consumers dueto their role in human health Fennel has been reportedto contain hydroxyl cinnamic acid derivatives flavonoidglycosides and flavonoid aglycones [67] The methanolicextract of fennel seeds contains rosmarinic acid chlorogenicacids as major phenolic compounds (149 and 68 resp)and quercetin and apigenin as themajor flavonoids (171 and125 resp) Also the total phenolic compounds in fennelmethanol extract were higher than the flavonoid compounds[23] F vulgare has been reported to contain phenolic acidslike 3-O-caffeoylquinic acid 4-O-caffeoylquinic acid 5-O-caffeoylquinic acid 13-O-di-caffeoylquinic acid 14-O-di-caffeoylquinic acid and 15-O-di-caffeoylquinic acid [65]Two compounds A and B were isolated and character-ized for the first time from the wild fennel and identi-fied as 34-dihydroxyphenethylalchohol-6-O-caffeoyl-120573-D-glucopyranoside and 3101584081015840-binaringenin respectively Thetotal phenolic and flavonoid contents ofwild fennel (24 and12 resp) were less as compared to cultivated fennel (31and 16 resp) [70]

4 Pharmacological Activities

Foeniculum vulgare is officially noted in Ayurvedic Pharma-copoeia as an important part of polyherbal formulations inthe treatment of different diseases and disorders A numberof biological-pharmacological studies have been undertakento evaluate the indigenous uses of F vulgare Few extracts of Fvulgare and isolated compounds have been evaluated for sev-eral activities namely antiaging antiallergic anticolitic anti-hirsutism anti-inflammatory antimicrobial and antiviralantimutagenic antinociceptive antipyretic antispasmodic

41 Antimicrobial and Antiviral Activities Foeniculum vul-gare has been used as an ethnic remedy for the cure ofnumerous infectious disorders of bacterial fungal viral andmycobacterial origin Several studies have been carried outin the past validating its antimicrobial antimycobacterialand antiviral potential (summarized in the Table 9) Duskoet al [91] investigated the antibacterial effect of the aqueousextract of 12 medicinal plants of Apiaceae family includingF vulgare An aqueous extract of the aerial part of Fvulgare inhibited the growth of Agrobacterium radiobacterpv tumefaciensErwinia carotovoraPseudomonas fluorescensand Pseudomonas glycinea (Table 9) An aqueous extract ofseed sample inhibited the growth of Enterococcus faecalisStaphylococcus aureus Escherichia coli Klebsiella pneumo-nia Pseudomona aeruginosa Salmonella typhi Salmonellatyphimurium Shigella flexneri and Bacillus cereus with 13ndash22 22ndash24 14ndash24 20-21 21ndash24 11-12 14ndash18 17ndash18 and 24ndash26mm zone of inhibition respectively [3 4] Gulfraz et al[92] investigated the antibacterial effect of the essential oil aswell as ethanolic and methanolic fruit extracts of F vulgareagainst Bacillus cereus Bacillus megaterium Bacillus pumilus

Bacillus subtilis Escherichia coliKlebsiella pneumoniaMicro-coccus luteus Pseudomonas putida Pseudomonas syringaeand Candida albicans According to the results reported byGulfraz et al [92] essential oil of F vulage had significantantimicrobial activities against some of microorganisms ascompared to the methanolic and ethanolic extracts Thediameters of growth inhibition zone ranged from 14 to 31mm(including the diameter of the disc 6mm) with the highestinhibition zone values observed against Bacillus megaterium(31mm) and Bacillus subtilis (29mm) Roby et al [23]investigated antimicrobial effect of the methanol ethanoldiethyl ether and hexane extracts of seed of F vulgare againsttwo species of Gram negative bacteria (Escherichia coli andSalmonella typhi) two species of Gram positive bacteria(Bacillus cereus and Staphylococcus aureus) one species ofyeast (Candida albicans) and one species ofmold (Aspergillusflavus)Themethanolic extract showedmore effective antimi-crobial activity than the other extracts The results fromthe disc diffusion method followed by measurement ofminimum inhibitory concentration (MIC) indicated thatBacillus cereus and Aspergillus flavus were the most sensitivemicroorganisms tested showing the largest inhibition zonesand the lowest MIC values Least activity was exhibitedagainstEscherichia coli with the smallest inhibition zones andthe highest MIC value [23] Shrivastava and Bhargava [93]investigated the antibacterial effect of the crude chloroformand methanol extract of leaves and flowers of F vulgarealong with Raphanus sativus and Brassica nigrum againstEscherichia coli and Staphylococcus aureus Methanol extractof flower of F vulgare showed significant activity againstEscherichia coli whereas crude and chloroform extractsfailed to exhibit antimicrobial activity against Staphylococcusaureus (Table 9) Among different tested bacterial strains the

methanolic fruit extract of F vulgare inhibited the growthof Staphylococcus aureus and Bacillus pumilus with 1127 and1267mm zone of inhibition respectively [7]

Several studies indicating the antifungal effect of Fvulgare along with antibacterial effect are also reported inthe literature Martins et al [94] investigated the antibacterialand antifungal effects of three essential oils of Portugueseplants namely Foeniculum vulgareMentha spicata and Ros-marinus officinalis against Staphylococcus aureus Escherichiacoli Klebsiella pneumonia Pseudomona aeruginosa Staphy-lococcus epidermidis Candida albicans and phytopathogenic

diseases [97] In an in vitro study aqueous and alcoholicseed extracts of F vulgare exhibited inhibitory effect againstAlternaria alternata Mucor rouxii and Aspergillus flavus[98] Interestingly aqueous seed extract of F vulgare showedstrongest antifungal activity as compared to reference fungi-cidal agent that is griseofulvin [99]

All of the above mentioned studies were carried outon the crude extracts and it is difficult to pinpoint theactive antimicrobial metabolite A phenylpropanoid deriva-tive called dillapional characterized from F vulgare stem wasfound to be an antimicrobial constituent with MIC values of125 250 and 125 against Bacillus subtilis Aspergillus nigerand Cladosporium cladosporioides respectively A coumarinderivative scopoletin was also isolated as a marginallyantimicrobial agent [100] The characterization of sevendifferent types of oxygenatedmonoterpenes frommethylene

chloride crude extract of F vulgare [101] suggested thatthe crude extract containing monoterpenes could be a newmedicinal resource for antibacterial agents

A total of 78 compounds were identified from theactive antimycobacterial fraction of F vulgare with thehelp of gas chromatography-mass spectra (GC-MS) Outof these twenty compounds were tested against one sensi-tive and three MDR strains of Mycobacterium tuberculosisusing the Alamar Blue microassay Compounds that showedsome degree of antimycobacterial activity against all strainstested were the following linoleic acid (MIC 100 120583gmL)oleic acid (MIC 100 120583gmL) 13-benzenediol (MIC 100ndash200120583gmL) undecanal (MIC 50ndash200120583gmL) and 24-undecadienal (MIC 25ndash50120583gmL) 24-Undecadienal wasthe most active compound against multidrug resistant Mtuberculosis speciesThus the dietary intake of F vulgaremaylower the risk ofM tuberculosis infection [63]

Orhan et al [5] studied the antiviral activity of theessential oil of fruit sample of F vulgare along with 12other Turkish medicinal plants against the DNA virusHerpessimplex type-1 (HSV-1) and the RNA virus parainfluenzatype-3 (PI-3) Most of the oils and compounds displayedstrong antiviral effects against HSV-1 ranging between 08and 0025 120583gmL However the samples tested were lesseffective against PI-3 with results ranging between 16 and02 120583gmL Only the essential oils of Anethum graveolensFoeniculum vulgare (fully mature) Mentha piperita Menthaspicata Ocimum minutiflorum Ocimum vulgaris and Sat-ureja cuneifolia inhibited this virus significantly

All these literature findings validated the traditional usesof Foeniculum vulgare in infectious disorders like abdomi-nal pains antiemetic arthritis conjunctivitis constipationdepurative diarrhea dieresis fever flatulence gastralgia gas-tritis insomnia irritable colon mouth ulcer stomachacherespiratory disorders skin diseases and so forth There isalways a need for new antimicrobial agents due to rapiddevelopment of resistance Bioactive metabolites of F vulgaremay be a potential source for new antimicrobial agents

42 Anti-Inflammatory Activity Oral administration ofmethanol extract of F vulgare fruit to rat and mice exhibitedinhibitory effects against acute and subacute inflammatorydiseases The anti-inflammatory activity of methanol extractwas evaluated by using three screening protocols namelycarrageenan-induced paw edema arachidonic acid-inducedear edema and formaldehyde-induced arthritis Theseare widely used for testing nonsteroidal anti-inflammatorydrugs For acute inflammationmethanol extract (200mgkg)exhibits significant inhibition of paw edema (69) inducedby carrageenan injection as compared to the control groupof animals Methanol extract of F vulgare also inhibitsear-edema (70) induced by arachidonic acid in mice Thelevel of serum transaminase aspartate aminotransferase(AST) and alanine aminotransferase (ALT) significantlyincreases in the presence of methanolic extract of F vulgareon inflammation induced by formaldehyde as comparedto control group The assessment of the level of AST and

ALT provides a good and simple tool to measure the anti-inflammatory activity of the target compounds [102] Theseoverall results seem to suggest that F vulgare FME mayact on both the cyclooxygenase and lipoxygenase pathways[79]

43 Antiallergic Activity Methanolic extract of F vulgarefruit showed significant inhibitory effect on DNFB- (24-dinitrofluorobenzene-) induced delayed type hypersensitiv-ity after oral administration of 200mgkg once a day for7 days The inhibitory effect on immunologically inducedswelling suggests the possible immunosuppressive propertiesof F vulgare [79]

44 Hepatoprotective Activity Essential oil of F vulgareseeds revealed a potent hepatoprotective effect against acutehepatotoxicity produced by carbon tetrachloride in ratsOral administration of F vulgare essential oil decreases thelevels of serum aspartate aminotransferase (AST) alanineaminotransferase (ALT) alkaline phosphatase (ALP) andbilirubin as compared to the control group Ozbek et alsuggest that the constituents (d-limonene and 120573-myrcene) ofessential oil may have played a key role in the protection ofliver from CCl

4toxicity [9]

45 Anxiolytic Activity Anxiety is the unpleasant feeling offear and concern When anxiety becomes excessive it maybe considered as an anxiety disorder Anxiolytic fennel isa drug used for the treatment of anxiety and its relatedpsychological and physical symptoms Naga Kishore et al[89] investigated the anxiolytic activity of ethanolic extract ofF vulgare fruit with the help of elevated plus maze rota rodopen field test and whole board models The 100 to 200mgdose of extract per kg of body weight of animal revealedsignificant activity when compared to reference anxiolyticdrug called diazepam (1mgkg) Thus fennel extract maypossess anxiolytic activity supporting its traditional claimabout anxiolytic activity reported in 19th edition of Pharma-cology and Pharmacotherapeutics by Sathodkar Bhandarkarand Rege

46 Antistress Activity Drug and food of natural originplay a significant role in public healthcare systems and arebeing investigated as remedies for a number of stress-relateddisorders [103]Thewhole plant extract of F vulgare exhibitednotable antistress effect against stress induced by forcefulswimming of test animals The key parameters that isurinary levels of vanillyl mandelic acid (VMA) and ascorbicacid in rats were used to evaluate antistress activity Theplant extract (50 100 and 200mgkg body weight) showeda significant improvement in urinary levels of VMA (119875 lt0001) and ascorbic acid excretion levels (119875 lt 0001) in testanimals when compared to the normal basal levels in controlgroup of animalsThus the extract of entire plant of F vulgareacts as an antistress agent [13]

47 Memory-Enhancing Property There are a number ofplants whose consumption is believed to enhance memory

22 BioMed Research International

and intelligence These were usually given to children as partof their food F vulgaris an ayurvedic rasayana (mixture)possessing multiple neuropharmacological activities Theantidepressant activity of fennel has been well documentedin ethnomedicine The whole plants extract (50 100 and200mgkg) of F vulgare exhibited memory-enhancing effectagainst scopolamine-induced amnesic rats This experimentwas evaluated by conditioned avoidance response (CAR)technique The CAR of rats administered with the extractincreased gradually to 95 over 7 to 12 days The acquisition(time to achieve 95 CAR) for rats administered with theextract was dose- and time-dependent compared to controlgroup which took 12 days for acquisition The percentavoidance was always higher in the extract-treated groupsas compared to control group Animals receiving 200mgkgbody weight of the extract took ten days while groups treatedwith 100 and 50mgkg doses of the extract required elevenand twelve days respectively to reach the point of acquisitionAdministration of scopolamine produced amnesia as seenfrom reduction in the observed CAR Amnesia was greaterin the control group than in extract-treated groups How-ever continued treatment with F vulgare produced betterretention and recovery in a dose-dependent manner thanthe vehicle-treated animals Recovery from scopolamine-induced amnesia in the extract-treated groups took 3ndash5 dayswhen compared to normal (control) group which took over6 days This overall progress suggests that F vulgare extractpossesses memory-enhancing property [13]

48 Nootropic Activity Alzheimerrsquos disease is a neurode-generative disorder associated with a decline in cognitiveabilities Dementia is one of the age-related mental problemsand a characteristic symptom of Alzheimerrsquos disease Thereis some evidence in favor of use of F vulgare for the treat-ment of cognitive disorders like dementia and Alzheimerrsquosdisease Methanol extract of the whole plant of F vul-gare administered for eight successive days ameliorated theamnesic effect of scopolamine and aging-induced memorydeficits inmiceThis extract increased step-down latency andacetylcholinesterase inhibition in mice significantly Thus Fvulgaremay be employed in treatment of cognitive disorderssuch as dementia and Alzheimerrsquos disease as a nootropic andanticholinesterase agent [80]

49 Antihirsutism Activity Idiopathic hirsutism is definedas the occurrence of excessive male pattern hair growth inwomen who have a normal ovulatory menstrual cycle andnormal levels of serum androgens It may be a disorder ofperipheral androgen metabolism Traditionally Foeniculumvulgare has been used as an estrogenic agent It has beenreputed to increase milk secretion promote menstruationfacilitate birth and increase libido On considering aboveaspect Javidnia and his research team evaluated the antihir-sutism activity of ethanolic extract of F vulgare seed againstidiopathic hirsutism by preparing cream containing 1 and 2of fennel extract The efficacy of treatment with the creamcontaining 2 fennel is better than the cream containing 1fennel and these two were more potent than placebo (control

group) The mean values of hair diameter reduction were78 183 and minus05 for patients receiving the creamscontaining 1 2 and 0 (placebo) respectively [78]

410 Estrogenic Properties Since the discovery of the estrusinducing effects of some plant products in 1926 consider-able effort has been devoted towards the characterizationof phytoestrogens including flavonoids isoflavonoids chal-cones coumestans stilbenes lignans saponins and essentialoils [16] F vulgare has estrogen-like activity In male ratstotal concentration of protein was found to be significantlydecreased in testes and in vasa deferentia whereas increasedin seminal vesicles and in prostate gland On the otherhand simultaneous decrease in the activities of acid andalkaline phosphatase in all these regions (except that alka-line phosphatase was unchanged in vasa) due to the oraladministration of acetone extract of F vulgare fruit wasobserved In female rats oral administration of the extract for10 days led to vaginal cornification and oestrus cycle [8] Totalconcentration of nucleic acids and protein as well as the organweights increased in both the tissues namely mammaryglands and oviducts due to the oral administration of acetoneextract (50 150 and 250120583g100 g body wt) of F vulgare seeds[104] Fennel oil was reported to exhibit estrogenic activitypromote menstruation and alleviate the symptoms of femaleclimacteric and increase libido [71] Administration of fenneloil (25 and 50 120583gmL final concentration in the organ bath)failed to exhibit any remarkable effect in uterine contrac-tion While 10 20 and 40 120583gml concentration of fennel oilrevealed significant inhibitory effect against prostaglandinE2 Fennel oil significantly reduces the frequency of uterinecontraction induced by prostaglandin E2 Thus the extractsof F vulgare have strong estrogenic activity [76]

411 Galactogenic Activity Foeniculum vulgare has been usedformillennia to increasemilk secretion [105]Thus F vulgarebelongs to galactagogue substance Structural similarity ofits main constituent anethole to dopamine seems to beresponsible for galactogenic activityDopamine acts to inhibitthe secretion of the milk-producing hormone prolactinAnethole might influence milk secretion by competing withdopamine at the appropriate receptor sites thereby inhibitingthe antisecretory action of dopamine on prolactin [71] It wasreported that anol (demethylated anethole) causes growthof the lobule-alveolar system in the mammary glands ofimmature female rabbits and induces menstruation in miceand other experimental animals Anol also gave positiveresults in the Jadassohn nipple test a test which involvesthe measurement of changes induced in the nipples ofguinea pigs subjected to the cutaneous application of sexhormones However further research suggests that the actualpharmacologically active agents responsible for galactogenicactivity are polymers of anethole such as dianethole andphotoanethole rather than anol or anethole itself [20 76]

412 Expectorant Activity F vulgare seeds stimulate theciliary motility of the respiratory apparatus and enhance the

BioMed Research International 23

external transport of extraneous corpuscles This action sug-gests a use for fennel in treating bronchial and bronchopul-monary afflictions and in particularly polluted environments[106] The volatile oil of F vulgare stimulates the contractionof the smooth muscles of the trachea an action that couldfacilitate the expectoration of mucus bacteria and othercorpuscles extraneous to the respiratory tracts [74]

413 Anticolitic Activity Essential oil of fennel regulates themotility of smooth muscles of the intestine while at thesame time reducing intestinal gas Alone or combined withother plant medicinals Foeniculum vulgare is indicated in thetreatment of spastic gastrointestinal disturbances in someforms of chronic colitis (which resist other treatments) indyspepsias from gastrointestinal atony in dyspepsias withthe sensation of heaviness in the stomach and so forthTheaddition of fennel to preparations containing anthraquinoniccomponents reduces the occurrence of abdominal pain oftenassociated with this type of laxative [73]

414 Antinociceptive Activity Antinociceptive means anysubstance that inhibits nociception which is a physiologicalprocess underlying the sensation of pain Briefly it reducesthe sensitivity to painful stimuli The various extracts ofaerial part of F vulgare namely hexane methylene chlorideethyl acetate and methanolic extract showed remarkableantinociceptive activity against acetic acid induced writhingin mice [68] The methanolic extract of the aerial parts ofF vulgare exhibited the highest antinociceptive activity at adose level of 2000mgkg while the activity exhibited by theethyl acetate extract was at dose level 800mgkgOn the otherhand n-hexane extract (700mgkg) and methylene chlorideextract (500mgkg) exhibited similar antinociceptive activi-ties being less than peripheral antinociceptive reference drug(acetyl salicylic acid) [68]

415 Diuretic Activity A diuretic is any substance thatpromotes the production of urine Briefly it is an agentthat promotes diuresis Diuretics work by promoting theexpulsion of urine (measured as the urine volume [UV]excreted) and urinary sodium (UNa) from the body and thishelps reduce the volume of blood circulating through thecardiovascular system Caceres et al [107] performed a studyin conscious animals and administered a powdered extractof the whole plant (F vulgare) which had no effect on UVor UNa The ethanolic extract of F vulgare fruit revealedexcellent diuretic activity and proves the earlier folk claimof F vulgare which was reported in the United State ofAmerica (Table 5) The fruit extract showed statistically ahighly significant diuretic effect F vulgare induced diuresis(500mgkg dose)was comparable to that of reference diureticagent urea (960mgkg dose) in mice with a urine outputthat was almost double that of the control group Thediuresis was not associated with changes in sodium andorpotassium excretion [108] In another part of the study theauthors showed that Foeniculum vulgare had little effect onthe noradrenalin contractile responses of aortic rings thus

suggesting that it worked mainly as a diuretic and natriureticwith little effect on arterial vascular tone [77]

416 Cardiovascular Activity An aqueous extract of F vul-gare leaves possesses potential cardiovascular action Thiseffect was investigated using pentobarbital-anaesthetisedmale albino Sprague-Dawley rats [75] An intravenousadministration of the lyophilized boiled water extract ofleaves produced a significant dose-related reduction in arte-rial blood pressure without affecting the heart rate or respi-ratory rate On the other hand the nonboiled aqueous extractshowed very little hypotensive activityThe hypotensive effectof the boiling water extract appeared not to be mediated viaadrenergicmuscarinic ganglionic or serotonergic receptorshowever histamine antagonists inhibited the hypotensiveeffect in a dose-related manner [75]

417 Oculohypotensive Activity The aqueous seed extract ofF vulgare demonstrated significant oculohypotensive activityusing water loading and steroid induced glaucoma modelThis extract exhibited 1749 2116 and 2203 reduction ofintraocular pressure in normotensive rabbits at 03 06and 12 (wv) concentrations respectively A maximummean difference of 3120 was observed between vehiclestreated and extracts treated eyes in water loading experi-mental animal model while a maximum mean intraocularpressure lowering of 3129 was observed in steroid inducedmodel of glaucoma Thus the aqueous extract of F vulgarerevealed oculohypotensive activity which was found to be asgood as that of reference standard antiglaucoma drugs calledtimolol [84]

418 Antithrombotic Activity Tognolini et al [55] providedevidence of potent inhibitory activity of essential oil of F vul-gare against platelet aggregation induced byADP arachidonicacid and collagen in guinea pig plasma Similar findingswere reported by Yoshioka and Tamada [109] for aggregationof rabbit platelets by an aromatic factor of fennel oil Theessential oil and anethole (a constituent of oil) of F vulgaretested in vitro in rat aorta with or without endotheliumdisplayed comparable NO-independent vasorelaxant activityat antiplatelet concentrations It supports the safety of Fvulgare that is free from cytotoxic effects Anethole and Fvulgare did not cause cytotoxicity when incubated for 30minupto 300 120583gmL in platelet viability test This concentrationwas largely compatible with those adopted in the functionalin vitro tests In vivo both F vulgare essential oil andanethole orally administered in a subacute treatment to mice(30mgkgday for 5 days) showed significant antithrom-botic activity preventing the paralysis induced by collagen-epinephrine intravenous injection (70 and 83 protectionresp)Thus essential oil and its main component anethole ofF vulgare showed a safe antithrombotic activity in guinea pigplasma that seems due to their broad spectrum antiplateletactivity clot destabilizing effect and vasorelaxant action [55]

419 Antimutagenic Effect Essential oil of F vulgare revealednoteworthy protective effects against genotoxicity in mice

24 BioMed Research International

induced by cyclophosphamide Genotoxicity and cytotoxicitywere assessed by using mice bone marrow chromosomalaberration micronucleus and sperm abnormality assaysrespectively Oral administration of essential oil (1 and2mLkg) significantly inhibited the frequencies of aberrantmetaphases chromosomal aberrations micronuclei forma-tion and cytotoxicity in mouse bone marrow cells inducedby cyclophosphamide and also produced a significant reduc-tion of abnormal sperm and antagonized the reduction ofcyclophosphamide induced superoxide dismutase catalaseand glutathione activities and inhibited increased malondi-aldehyde content in the liver Additionally F vulgare inhibitsthe oxidative stress induced by cyclophosphamide [90]

420 Gastrointestinal Effect Theaqueous extract of F vulgareshowed remarkable antiulcerogenic effect against ethanol-induced gastric lesions in rats It was found that pretreatmentwith aqueous extract significantly reduced ethanol-inducedgastric damageThis effect of aqueous extract was highest andstatistically significant in 300mgkg group comparedwith thecontrol (119875 lt 0001) group of animal Additionally aqueousextract of F vulgare significantly reduced the whole bloodmalondialdehyde levels while significantly increased nitritenitrate ascorbic acid retinol and beta-carotene levels Thusaqueous extract of F vulgare fruit had clearly a protectiveeffect against ethanol-induced gastric mucosal lesion in rats[81]

421 Chemomodulatory Action The chemopreventive effectof different doses of test diet of Foeniculum vulgare seeds wasexamined against 712-dimethylbenz(a)anthracene- (DMBA-) induced skin papillomagenesis and benzo(a)pyrene-[B(a)P-] induced forestomach papillomagenesis at the peri-initiational level in Swiss albino mice Fennel seeds exhibita significant reduction in the skin and the fore-stomachtumor incidence and tumor multiplicity as compared tothe control group Further biochemical assays showeda significant increase in the contentactivities of phase Ienzymes especially in the case of 6 test diet A concomitantincrease in the activities of the phase II enzymes wasobserved with all the doses of test diet under study Asignificant enhancement in the activities of antioxidantenzymes was observed especially at 4 and 6 test diets offennel These findings were indicative of chemopreventivepotential of fennel against carcinogenesis This is the firstreport showing chemopreventive potential of seeds of fennelagainst carcinogenesis [85]

422 Cytoprotection and Antitumor Activity Anethole is theprincipal active component of fennel seeds which has exhib-ited anticancer activity Al-Harbi et al studied the antitumoractivity of anethole against Ehrlich ascites carcinoma inducedin a tumor model in Swiss albino mice The study revealedthat anethole increased survival time reduced tumor weightand reduced the volume and body weight of the Ehrlichascites tumour-bearing mice It also produced a significantcytotoxic effect in the Ehrlich ascites tumour cells in the pawreduced the levels of nucleic acids and malondialdehyde and

increased glutathione concentrations [110] In vitro cytopro-tection activity of methanolic extract of Foeniculum vulgarewas evaluated against normal human blood lymphocytes bymicronucleus assay and antitumor activity against B16F10melanoma cell line by Trypan blue exclusion assay for cellviability Lymphocyte culture treated with 70 methanolicextract of Foeniculum vulgare showed very less percentage ofmicronucleus that is 0006 as compared to standard drugdoxorubicin which showed 0018 micronucleus On theother hand 70methanolic extract of Foeniculum vulgare haspotent antitumor activity at the concentration of 200120583gmLThe results suggest that the Foeniculum vulgare could beconsidered as a natural resource of antitumor agents as wellas cytoprotective to normal cells [11]

423 Cytotoxicity Kaileh and his coworker investigated thecytotoxic effect of organic extracts of 24 selected Palestinianmedicinal plant species The plant selection was based onexisting ethnobotanic information and interviews with localhealers The extracts of the plants under investigation weretested for their potential antitumor (cytotoxic) effect on themurine fibrosarcoma L929sA cells and on the human breastcancer cells MDA-MB231 and MCF7 The extract from Fvulgare presented an IC (50) value at 24 h of 700 plusmn 28 and500plusmn17 120583gmL on L929sA andMCF7 cells respectivelyThenuclear transcription factor NFkappaB or NF120581B regulatesthe expression of various genes They further investigatedthe effect of nine promising plant extracts withheld fromthe first cell viability screening on NF120581B activation Thedichloromethane and methanol (1 1) extract of aerial part ofF vulgare revealed immunomodulatory NF120581B activities [82]Also Berrington and Lall investigated the in vitro cytotoxicityof acetone extracts of F vulgare and other eight medicinalplants against a noncancerous African green monkey kidney(Vero) cell line and an adenocarcinoma cervical cancer(HeLa) cell line [87]

424 Antipyretic Activity F vulgare extract showedantipyretic activity against hyperpyrexia in mice It wasinduced by SC administration of 2mL100 g of a 20aqueous suspension of brewerrsquos yeast As an antipyreticagent ethanolic extract of F vulgare fruit showed a moderateantipyretic activity that was statistically significant after 30and 90min (119875 lt 001) [108]

425 Hypolipidemic Activity The aqueous extract of F vul-gare revealed notable hypolipidemic and antiatherogenicactivity against Triton WR-1339 induced hyperlipidemiain mice Aqueous extract causes significant reduction ofplasma lipid levels that is cholesterol triglycerides LDL-cholesterol and apolipoprotein-B decreased by 40 2361 and 61 respectively and increase in HDL-cholesteroland apolipoprotein A1 by 85 and 58 respectively [88]

426 Hypoglycemic Activity The essential oil of F vulgareexhibits potential hypoglycemic and antioxidant activityagainst streptozotocin induced diabetes in rats Essentialoil (30mgkg body weight) of F vulgare works in the

correction of hyperglycemia from 1625 plusmn 319mgdL to8197 plusmn 197mgdL with 119875 lt 005 and the activity of serumglutathione peroxidase from 5972 plusmn 278Ug Hb to 9960 plusmn638Ug Hb with 119875 lt 005 Also essential oil of fennelimproves the pathological changes noticed in their kidneyand pancreas as compared with the control group of animalThis can prove its effect as antidiabetic in folk Medicine Thismakes the possibility of its inclusion in antidiabetic drugindustry [12]

427 Antispasmodic Activity The antispasmodic activity of25 and 100mLL of alcoholic extract of Foeniculum vulgarealong with other Germanic medicinal plants namelyMelissaofficinalis Rosmarinus officinalisMentha piperitaMatricariachamomilla Carum carvi and Citrus aurantium were testedemploying the guinea pig ileum and using acetylcholine andhistamine as spasmogens An alcoholic extract of the fruits ofFoeniculum vulgare possesses antispasmodic activity whichinhibits the acetylcholine and histamine-induced guineapig ileal contractions in vitro An essential oil which isobtained from the fruits of Foeniculum vulgare 25 120583gmL and10 120583gmL respectively inhibited oxytocin and prostaglandin[72]

428 Apoptotic Activity The apoptotic activities of ethanolextracts from fruits of seven species of Apiaceae familynamely Eryngium planum Archangelica officinalis Pasti-naca sativa Heracleum sibiricum Carum carvi Foenicu-lum vulgare and Levisticum officinale against ML-1mdashhumanacute myeloblastic leukaemia J-4501mdashhuman acute Tcell leukaemia EOLmdashhuman eosinophilic leukaemia HL-60mdashhuman Caucasian promyelocytic leukaemia 1301mdashhuman T cell leukaemia lymphoblast C-8166mdashhuman Tcell leukaemia U-266B1mdashhuman myeloma WICLmdashhumanCaucasian normal B cell and H-9mdashhuman T cell wereinvestigated with the help of Trypan blue assay and AnnexinV fluos assay [86] The ethanol extract from fruit F vulgareshowed the highest mortality in Trypan blue test for J45cell linemdash4 of viable cells and for C8166 cell linemdash100of mortality However the cells of other lines showed thehighest viability HL60mdash60 EOLmdash48 and MLmdash1ndash42The normal cell line H9 and WICL showed 35 and 25of viable cells respectively C8166 cell line and J-45 cell lineshowed the highest level of the apoptotic cells detected byAnnexin V methodmdash100 and 93 respectively Howeverthe cells of two lines HL60 and EOL-1 showed the lowerlevels of apoptotic cellsmdash52 and 60 respectively Highpercentage of apoptotic cells was observed inH9 andWICLmdash76 and 93 respectively [86]

429 Human Liver Cytochrome P450 3A4 Inhibitory ActivityThirteen compounds isolated from the methanolic extract offennel have been found to possess human liver cytochromeP450 3A4 inhibitory activity Among these compounds 5-methoxypsoralen (5-MoP) showed the strongest inhibitionwith an IC50 value of 183120583m and with a mixed type ofinhibition [83]

430 Antiaging Effects Rasul and his coworker developeda base and formulation containing 4 concentrated seedextract of F vulgare This formulation shows notable antiag-ing effect with supporting experimental data related to skinmoisture and transepidermal water loss (TEWL) The basewas insignificant while the formulation showed significanteffects on skin moisture and TEWL The texture parameterenergy showed a significant increase proving that the formu-lation possesses potential antiaging effects [50]

431 Bronchodilatory Effect Ethanol extract and essential oilfrom F vulgare exhibited bronchodilatory activity on con-tracted tracheal chains of guinea pig The potassium channelopening effect of fennel may contribute on its relaxant effecton guinea pig tracheal chains [111] Moreover anethole bearsa striking resemblance to the catecholamines epinephrinenorepinephrine and dopamine This structural similarityappears to be responsible for the various sympathomimeticactivities of F vulgare such as bronchodilatory effect [71]

432 Antioxidant Activities Naturally occurring antioxi-dants can be used to protect human beings from oxidativestress damage [112] Fennel was known as excellent source ofnatural antioxidants and contributed to the daily antioxidantdiet [113]Wild fennel was found to exhibit a free radical scav-enging activity with higher content phenolic and flavonoidthan medicinal and edible fennel and the aerial parts ofthe Italian fennel populations showed the highest DPPHscavenging activity [65] Phenolic compounds of fennelincluding caffeoylquinic acid rosmarinic acid eriodictyol-7-orutinoside quercetin-3-O-galactoside and kaempferol-3-O-glucoside showed antioxidant activities [67] The volatileoil showed strong antioxidant activity in comparison withbutyrated hydroxyanisole and butylated hydroxytolueneEthanol and water extracts of fennel showed less antioxidantactivity compared with essential oil [114]

5 Environmental Application

Foeniculum vulgare that is fennel not only exhibited phar-macological activities but also revealed a few environmentalactivities These activities play a key role in the managementof nematode insect mosquitoes and some harmful larvae ofmalaria producing vector Thus the extracts of F vulgare andisolated biologically active compounds have been evaluatedfor their insecticidal repellent acaricidal larvicidal andnematicidal activity [115ndash119] A brief review on the differenttype of ecofriendly environmental activities as reported onthis plant is summarized below

51 Insecticidal Activities The fruit derived phytoconstitu-ents of F vulgare exhibited prominent insecticidal activi-ties against Sitophilus oryzae Callosobruchus chinensis andLasioderma serricorne This activity was examined usingdirect contact application and fumigation methods Thebiologically active constituents that is phenylpropenes (E)-anethole and estragole and the monoterpene (+)-fenchonewere characterized from Foeniculum fruit By using a filter

paper diffusion test estragole (0168mg cmminus2) caused 91mortality to S oryzae within 1 day after treatment whereas(+)-fenchone and (E)-anethole gave over 90 mortality at 2and 4 day after treatment respectively

After 2 days of treatment all test compounds (0021mg cmminus2 concentration) revealed potent insecticidal activityagainst C chinensis Whereas after 1 day of treatment (E)-anethole (0105mg cmminus2) gave 100mortality of L serricornewhereas 90 and 60 mortality at 4 day after treatment wasachieved with estragole and (+)-fenchone respectively In afumigation test the compounds were much more effectiveagainst adults of S oryzae C chinensis and L serricorne inclosed cups than in open ones indicating that the insecticidalactivity of test compounds was largely attributable to fumi-gant action As naturally occurring insect-control agents theF vulgare fruit-derived materials described could be usefulfor managing field populations of S oryzae C chinensis andL serricorne [116]

52 Acaricidal Activity Fennel oil shows significant acaricid-al activity againstDermatophagoides farinae andDermatoph-agoides pteronyssinus (+)-fenchone and p-anisaldehyde aremajor constituents of fruit oil of F vulgare P-anisaldehydewas the most toxic compound against D farinae and is muchmore effective compared with benzyl benzoate thymol andestragol [118]

53 Repellent Activity The methanolic extract of fruits ofF vulgare was spectroscopically characterized for the pres-ence of biologically active constituents called (+)-fenchoneand (E)-9-octadecenoic acid The repellent activity of theseconstituents was tested against hungry Aedes aegypti femaleswith the help of skin and patch tests and compared withthat of the commercial repellent agent called NN-diethyl-m-toluamide (DEET) and (Z)-9-octadecenoic acid In askin test with female mosquitoes (+)-fenchone and (Z)-9-octadecenoic acid (04mgcm2) exhibitedmoderate repellentactivity at 30min after treatment whereas DEET providedgt1 h of protection against adult mosquitoes at (02mgcm2)Thus (+)-Fenchone and (E)-9-octadecenoic acid are poten-tial mosquito repellent agents or lead compounds [117]

54 Larvicidal Activity Plant extracts and oils may act asalternatives to conventional pesticides for malaria vectorcontrol By considering this aspect Sedaghat et al [119] inves-tigated the larvicidal activity of essential oils of three plantsof Apiaceae family against malaria vector called Anophe-les stephensi The larvicidal activity was evaluated againstlaboratory-reared larvae by standard method of WHO TheF vulgare oil was the most effective against A stephensiwith LC(50) and LC(90) values of 2010 and 4451 ppmrespectively [119] Additionally the essential oil extracts fromleaves flowers and roots of F vulgare exhibit noticeablelarvicidal activity against fourth-instar larvae of themosquitoCulex pipiens molestus Terpineol and 18-cineole content of Fvulgare are the most effective phytoconstituent against Culexpipiens molestus bites offering complete protection for 16 and2 h respectively [120] Recently Zoubiri et al [57] reported

the larvicidal activity of essential oil of fennel seed againstCulex pipiensmosquitoThus F vulgare can serve as a naturallarvicidal agent

55 Nematicidal Activity Oka et al investigated the in vitronematicidal activity of essential oils extracted from 27 spicesand aromatic plants in pot experiments Twelve of thetwenty-seven essential oils immobilized more than 80 ofjuveniles of the root-knot nematodeMeloidogyne javanica ata concentration of 1000 120583Lliter At this concentration mostof these oils also inhibited nematode hatching Essential oilsof Carum carvi Foeniculum vulgare Mentha rotundifoliaand Mentha spicata showed the highest nematicidal activityamong the in vitro tested oils In 3-liter pot experimentsnematicidal activity of the essential oils and their componentswas confirmed at 200 and 150mgkg respectivelyThe resultssuggest that the essential oils and theirmain componentsmayserve as nematicides [115]

6 Toxicity

The long history of ethnomedicinal application with noreports of any serious side effects suggests that F vulgarecould be considered as safe Inmost toxicity experiments car-ried out on F vulgare no sign of toxicity was observed Shahand his coworker in 1991 investigated the detailed toxicityaccount of ethanolic extract of fennel fruit in experimentalmice with respect to acute and 90 days longer term toxicity[121] In experimentation Shah and his coworker observedthe general symptoms of toxicity and mortality for only 24 hin acute toxicity Whereas in another part of toxicity theystudied the effect of fennel extract on mice with 90 dayslong term treatment Acute toxicity of ethanolic extract of Fvulgarewas assessed in 35mice by using three concentrationsnamely 05 1 and 3 gkg body weight In this investigation Fvulgare exhibited no signs of toxicity and no mortality wasobserved upto the dose level 3 gkg body weight In case oflonger term toxicity ethanolic extract of F vulgare (100mgkgbody weightday) was given in drinking water of animals(30 male and 30 female mice) All external morphologicalhaematological and spermatogenic changes in addition tobody and vital organ weights were recorded The extractcaused no significant chronic mortality as compared tocontrols during this investigation The treated male micegained significant weight during chronic treatment while aloss or no significant change in weight was noticed in thefemale mice treated with the same extract The extracts didnot show spermatotoxic effects Thus Shah and his coworkerconcluded that fennel extract is safe based on both acuteandor long term toxicity studies [121] Additionally the plantextract in doses of 05 1 and 3 gkg (orally) did not causeany deaths These doses do not show any type of toxicityagainst several parameters tested namely locomotor activitybizarre reactions sensitivity to sound social interaction tailposture aggressive behaviour ataxia paralysis convulsionstremors prostration exophthalmos pupil size defecationsalivation urination pattern of respiration nasal dischargecyanosis and piloerection Exceptionally only the 3 gkg dose

BioMed Research International 27

showed signs of reduced locomotor activity and piloerec-tion Otherwise all other parameters were negative [108]In another experiment of acute toxicity different solventextracts namely n-hexane methylene chloride ethyl acetateand methanol extracts of F vulgare upto 55 gkg concentra-tion did not revealed any kind of toxicity in mice LD50being 675 110 692 and 15 gkg for n-hexane methylenechloride ethyl acetate and methanol extracts respectively[68] The plant extract of F vulgare was administered orallyat a dose of 100 200 400 600 800 1000 and 2000mgkgof body weight of mice Each group of animals was undervisual observation for 10 days for the external behavior ofneurological toxicity created by plant extract Even the micereceiving highest dose of F vulgare extract did not show anymortality or toxicity demonstrating the safety profile of theplant extract [89]

The acute oral 50 LD50 for anethole in rats was foundto be 2090mgkg Repeated doses of one-third the LD50 ofanethole (695mgkg) given to rat caused mild liver lesionsIt would therefore appear that in normal therapeutic dosagesanethole would have minimal hepatotoxicity When anetholewas fed to rats daily for one year as 025 of the dietno hepatic damage was seen [122] The acute oral LD50 ofessential oil in rats is 1326mgkg [76] The use of F vulgareessential oil as a remedy for control of primary dysmenorrheaincreases concern about its potential teratogenicity due toits estrogen like activity Evaluation of teratogenicity ofessential oil using limb bud mesenchymal cells showed thatthe essential oil may have toxic effect on fetal cells butthere was no evidence of teratogenicity upto concentrationof 93mgmL of culture medium [123] The overall toxicitystudies carried out on F vulgare accounts for its safety at therecommended therapeutic doses

7 Conclusions

The available scientific research on Foeniculum vulgarehas shown that it is an important medicinal plant used ina wide range of ethnomedical treatments especially forabdominal pains antiemetic aperitif arthritis cancer colicin children conjunctivitis constipation depurative diarrheadieresis emmenagogue fever flatulence gastralgia gastritisinsomnia irritable colon kidney ailments as a laxativeleucorrhoea liver pain mouth ulcer and stomachache Thisplant has been in use for a long period of time withoutany documented serious adverse effects Studies carriedout in the past and present indicate that fennel possessesdiverse health benefits and are an important constituentof food Studies have shown that various extracts offennel possess a range of pharmacological actions such asantiaging antiallergic anticolitic antihirsutism anti-inflam-matory antimicrobial and antiviral antimutagenic antino-ciceptive antipyretic antispasmodic antistress antithromb-otic anxiolytic apoptotic cardiovascular chemomodulatoryaction cytoprotection and antitumor cytotoxicity diureticestrogenic properties expectorant galactogenic gastrointes-tinal effect hepatoprotective human liver cytochrome P4503A4 inhibitory hypoglycemic hypolipidemic memory-en-hancing property nootropic and oculohypotensive activity

supporting its traditional use However the most prominentand the well studied effects are the antimicrobial andantioxidant effects of essential oil of fennel in differentexperimental models The observed health benefits may becredited to the presence of the various phytochemicals likevolatile compounds flavonoids phenolic compounds fattyacids and amino acids

Fennel also contains mineral and trace elements likealuminum barium calcium cadmium cobalt chromiumcopper ironmagnesiummanganese nickel lead strontiumand zinc [124] fat soluble vitamins such as vitamins A Eand K water soluble vitamins like ascorbic acid thiamineriboflavin niacin and pyridoxine essential amino acidslike leucine isoleucine phenylalanine and tryptophane maycontribute to the myriad health beneficial effects at least inpart

Most of the pharmacological studies were conductedusing uncharacterized crude extracts of fennel It is difficultto reproduce the results of these studies and pinpoint thebioactive compounds Hence there is a need for chemi-cal standardization and bioactivity-guided identification ofbioactive compounds Among several classes of chemicalconstituents identified in fennel volatile components of fen-nel essential oil and phenolic compounds are assumed to bethe main bioactive compounds responsible for the majorityof its pharmacological effects However the vast traditionaluse and proven pharmacological activities of fennel indicatethat an immense scope still exists for its chemical explorationFuture studies should be focused on validating the mecha-nism of action responsible for the various beneficial effectsand also on understanding which plant based compounds areresponsible for the reported effectsThe required informationwhen available will enhance our knowledge and appreciationfor the use of fennel in our daily diet Also the outcomeof such chemical studies may further expand its existingtherapeutic potential

Thus there are many areas of research related to thisplant that need to be further explored to fully recognize itsbeneficial effects for society Factors such as geographical andseasonal variation play an important role in the authentica-tion of the chemical constituents responsible for the activitywhich also can be an area of interest Thus it is incumbenton researchers to fill the huge gap of insufficient knowledgeand create awareness among pharmacologists as well as inves-tigators towards providing better medicinal value derivedfrom this plant This can be fulfilled only by generatinginterest among the research community through writing ofcritical appraisals (paper) and extending the interdisciplinaryresearch area to focused studies on Foeniculum vulgare

Turkish [51 56] Serbian [52] Indian [54] and Chinese [53]fennels The hexane extracts of fennel were analyzed by GC-MS and 78 compounds were identified from these extractsthe major compounds were identified as 13-benzenediol 1-methoxycyclohexene o-cymene sorbic acid 2-hydroxy-3-methyl-2-cyclopenten-1-one estragole limonene-10-ol and3-methyl-2-cyclopenten-1-one [63] Diao et al [64] identifya total of 28 components by GC and GCMS from fenneloil representing 958 of the total amount Trans-Anethole(6853) a phenylpropanoid was found to be the maincomponent followed by estragole (1042) with limonene(624) fenchone (545) and others as minor components

32 Flavonoids Flavonoids are generally considered as animportant category of antioxidants in the human dietFlavonoids are abundant in the plants of Apiaceae family Ithas been reported that the presence of flavonol glycosidesin fennel species is related to its morphological hetero-geneity and variation Total flavonoid content of hydroal-coholic extracts is about 123 plusmn 018mgg Flavonoids likeeriodictyol-7-rutinoside quercetin-3-rutinoside and ros-marinic acid have been isolated from F vulgare [65]Amongst the flavonoids present in F vulgare the most preva-lent are quercetin-3-glucuronide isoquercitrin quercetin-3-arabinoside kaempferol-3-glucuronide and kaempferol-3-arabinoside and isorhamnetin glucoside [66] Quercetin-3-O-galactoside kaempferol-3-O-rutinoside and kaempferol-3-O-glucoside have also been reported to occur in the aque-ous extract of F vulgare [67] The flavonoids like isorham-netin 3-O-120572-rhamnoside quercetin and kaempferol werealso isolated from the ethyl acetate extract whereas quercetin3-O-rutinoside kaempferol 3-O-rutinoside and quercetin3-O-120573-glucoside were isolated from the methanol extractThese flavonoids exhibit remarkable antinociceptive and anti-inflammatory activity [68] Further quercetin rutin andisoquercitrin were reported to have the immunomodulatoryactivities [69]

33 Phenolic Compounds There has been a growing interestin phenolic components of fruits and vegetables which maypromote human health or lower the risk of disease Aqueous

extract of fennel fruits are rich in phenolic compoundsMany of them have antioxidant activities and hepatopro-tective properties The phenolic compounds present in Fvulgare are considered to be associated with the preventionof diseases possibly induced by oxidative stress such ascardiovascular diseases cancer and inflammation Thesephenolic compounds have received tremendous attentionamong nutritionists food scientists and consumers dueto their role in human health Fennel has been reportedto contain hydroxyl cinnamic acid derivatives flavonoidglycosides and flavonoid aglycones [67] The methanolicextract of fennel seeds contains rosmarinic acid chlorogenicacids as major phenolic compounds (149 and 68 resp)and quercetin and apigenin as themajor flavonoids (171 and125 resp) Also the total phenolic compounds in fennelmethanol extract were higher than the flavonoid compounds[23] F vulgare has been reported to contain phenolic acidslike 3-O-caffeoylquinic acid 4-O-caffeoylquinic acid 5-O-caffeoylquinic acid 13-O-di-caffeoylquinic acid 14-O-di-caffeoylquinic acid and 15-O-di-caffeoylquinic acid [65]Two compounds A and B were isolated and character-ized for the first time from the wild fennel and identi-fied as 34-dihydroxyphenethylalchohol-6-O-caffeoyl-120573-D-glucopyranoside and 3101584081015840-binaringenin respectively Thetotal phenolic and flavonoid contents ofwild fennel (24 and12 resp) were less as compared to cultivated fennel (31and 16 resp) [70]

4 Pharmacological Activities

Foeniculum vulgare is officially noted in Ayurvedic Pharma-copoeia as an important part of polyherbal formulations inthe treatment of different diseases and disorders A numberof biological-pharmacological studies have been undertakento evaluate the indigenous uses of F vulgare Few extracts of Fvulgare and isolated compounds have been evaluated for sev-eral activities namely antiaging antiallergic anticolitic anti-hirsutism anti-inflammatory antimicrobial and antiviralantimutagenic antinociceptive antipyretic antispasmodic

methanolic fruit extract of F vulgare inhibited the growthof Staphylococcus aureus and Bacillus pumilus with 1127 and1267mm zone of inhibition respectively [7]

Several studies indicating the antifungal effect of Fvulgare along with antibacterial effect are also reported inthe literature Martins et al [94] investigated the antibacterialand antifungal effects of three essential oils of Portugueseplants namely Foeniculum vulgareMentha spicata and Ros-marinus officinalis against Staphylococcus aureus Escherichiacoli Klebsiella pneumonia Pseudomona aeruginosa Staphy-lococcus epidermidis Candida albicans and phytopathogenic

diseases [97] In an in vitro study aqueous and alcoholicseed extracts of F vulgare exhibited inhibitory effect againstAlternaria alternata Mucor rouxii and Aspergillus flavus[98] Interestingly aqueous seed extract of F vulgare showedstrongest antifungal activity as compared to reference fungi-cidal agent that is griseofulvin [99]

All of the above mentioned studies were carried outon the crude extracts and it is difficult to pinpoint theactive antimicrobial metabolite A phenylpropanoid deriva-tive called dillapional characterized from F vulgare stem wasfound to be an antimicrobial constituent with MIC values of125 250 and 125 against Bacillus subtilis Aspergillus nigerand Cladosporium cladosporioides respectively A coumarinderivative scopoletin was also isolated as a marginallyantimicrobial agent [100] The characterization of sevendifferent types of oxygenatedmonoterpenes frommethylene

chloride crude extract of F vulgare [101] suggested thatthe crude extract containing monoterpenes could be a newmedicinal resource for antibacterial agents

A total of 78 compounds were identified from theactive antimycobacterial fraction of F vulgare with thehelp of gas chromatography-mass spectra (GC-MS) Outof these twenty compounds were tested against one sensi-tive and three MDR strains of Mycobacterium tuberculosisusing the Alamar Blue microassay Compounds that showedsome degree of antimycobacterial activity against all strainstested were the following linoleic acid (MIC 100 120583gmL)oleic acid (MIC 100 120583gmL) 13-benzenediol (MIC 100ndash200120583gmL) undecanal (MIC 50ndash200120583gmL) and 24-undecadienal (MIC 25ndash50120583gmL) 24-Undecadienal wasthe most active compound against multidrug resistant Mtuberculosis speciesThus the dietary intake of F vulgaremaylower the risk ofM tuberculosis infection [63]

Orhan et al [5] studied the antiviral activity of theessential oil of fruit sample of F vulgare along with 12other Turkish medicinal plants against the DNA virusHerpessimplex type-1 (HSV-1) and the RNA virus parainfluenzatype-3 (PI-3) Most of the oils and compounds displayedstrong antiviral effects against HSV-1 ranging between 08and 0025 120583gmL However the samples tested were lesseffective against PI-3 with results ranging between 16 and02 120583gmL Only the essential oils of Anethum graveolensFoeniculum vulgare (fully mature) Mentha piperita Menthaspicata Ocimum minutiflorum Ocimum vulgaris and Sat-ureja cuneifolia inhibited this virus significantly

All these literature findings validated the traditional usesof Foeniculum vulgare in infectious disorders like abdomi-nal pains antiemetic arthritis conjunctivitis constipationdepurative diarrhea dieresis fever flatulence gastralgia gas-tritis insomnia irritable colon mouth ulcer stomachacherespiratory disorders skin diseases and so forth There isalways a need for new antimicrobial agents due to rapiddevelopment of resistance Bioactive metabolites of F vulgaremay be a potential source for new antimicrobial agents

42 Anti-Inflammatory Activity Oral administration ofmethanol extract of F vulgare fruit to rat and mice exhibitedinhibitory effects against acute and subacute inflammatorydiseases The anti-inflammatory activity of methanol extractwas evaluated by using three screening protocols namelycarrageenan-induced paw edema arachidonic acid-inducedear edema and formaldehyde-induced arthritis Theseare widely used for testing nonsteroidal anti-inflammatorydrugs For acute inflammationmethanol extract (200mgkg)exhibits significant inhibition of paw edema (69) inducedby carrageenan injection as compared to the control groupof animals Methanol extract of F vulgare also inhibitsear-edema (70) induced by arachidonic acid in mice Thelevel of serum transaminase aspartate aminotransferase(AST) and alanine aminotransferase (ALT) significantlyincreases in the presence of methanolic extract of F vulgareon inflammation induced by formaldehyde as comparedto control group The assessment of the level of AST and

ALT provides a good and simple tool to measure the anti-inflammatory activity of the target compounds [102] Theseoverall results seem to suggest that F vulgare FME mayact on both the cyclooxygenase and lipoxygenase pathways[79]

43 Antiallergic Activity Methanolic extract of F vulgarefruit showed significant inhibitory effect on DNFB- (24-dinitrofluorobenzene-) induced delayed type hypersensitiv-ity after oral administration of 200mgkg once a day for7 days The inhibitory effect on immunologically inducedswelling suggests the possible immunosuppressive propertiesof F vulgare [79]

44 Hepatoprotective Activity Essential oil of F vulgareseeds revealed a potent hepatoprotective effect against acutehepatotoxicity produced by carbon tetrachloride in ratsOral administration of F vulgare essential oil decreases thelevels of serum aspartate aminotransferase (AST) alanineaminotransferase (ALT) alkaline phosphatase (ALP) andbilirubin as compared to the control group Ozbek et alsuggest that the constituents (d-limonene and 120573-myrcene) ofessential oil may have played a key role in the protection ofliver from CCl

4toxicity [9]

45 Anxiolytic Activity Anxiety is the unpleasant feeling offear and concern When anxiety becomes excessive it maybe considered as an anxiety disorder Anxiolytic fennel isa drug used for the treatment of anxiety and its relatedpsychological and physical symptoms Naga Kishore et al[89] investigated the anxiolytic activity of ethanolic extract ofF vulgare fruit with the help of elevated plus maze rota rodopen field test and whole board models The 100 to 200mgdose of extract per kg of body weight of animal revealedsignificant activity when compared to reference anxiolyticdrug called diazepam (1mgkg) Thus fennel extract maypossess anxiolytic activity supporting its traditional claimabout anxiolytic activity reported in 19th edition of Pharma-cology and Pharmacotherapeutics by Sathodkar Bhandarkarand Rege

46 Antistress Activity Drug and food of natural originplay a significant role in public healthcare systems and arebeing investigated as remedies for a number of stress-relateddisorders [103]Thewhole plant extract of F vulgare exhibitednotable antistress effect against stress induced by forcefulswimming of test animals The key parameters that isurinary levels of vanillyl mandelic acid (VMA) and ascorbicacid in rats were used to evaluate antistress activity Theplant extract (50 100 and 200mgkg body weight) showeda significant improvement in urinary levels of VMA (119875 lt0001) and ascorbic acid excretion levels (119875 lt 0001) in testanimals when compared to the normal basal levels in controlgroup of animalsThus the extract of entire plant of F vulgareacts as an antistress agent [13]

47 Memory-Enhancing Property There are a number ofplants whose consumption is believed to enhance memory

22 BioMed Research International

and intelligence These were usually given to children as partof their food F vulgaris an ayurvedic rasayana (mixture)possessing multiple neuropharmacological activities Theantidepressant activity of fennel has been well documentedin ethnomedicine The whole plants extract (50 100 and200mgkg) of F vulgare exhibited memory-enhancing effectagainst scopolamine-induced amnesic rats This experimentwas evaluated by conditioned avoidance response (CAR)technique The CAR of rats administered with the extractincreased gradually to 95 over 7 to 12 days The acquisition(time to achieve 95 CAR) for rats administered with theextract was dose- and time-dependent compared to controlgroup which took 12 days for acquisition The percentavoidance was always higher in the extract-treated groupsas compared to control group Animals receiving 200mgkgbody weight of the extract took ten days while groups treatedwith 100 and 50mgkg doses of the extract required elevenand twelve days respectively to reach the point of acquisitionAdministration of scopolamine produced amnesia as seenfrom reduction in the observed CAR Amnesia was greaterin the control group than in extract-treated groups How-ever continued treatment with F vulgare produced betterretention and recovery in a dose-dependent manner thanthe vehicle-treated animals Recovery from scopolamine-induced amnesia in the extract-treated groups took 3ndash5 dayswhen compared to normal (control) group which took over6 days This overall progress suggests that F vulgare extractpossesses memory-enhancing property [13]

48 Nootropic Activity Alzheimerrsquos disease is a neurode-generative disorder associated with a decline in cognitiveabilities Dementia is one of the age-related mental problemsand a characteristic symptom of Alzheimerrsquos disease Thereis some evidence in favor of use of F vulgare for the treat-ment of cognitive disorders like dementia and Alzheimerrsquosdisease Methanol extract of the whole plant of F vul-gare administered for eight successive days ameliorated theamnesic effect of scopolamine and aging-induced memorydeficits inmiceThis extract increased step-down latency andacetylcholinesterase inhibition in mice significantly Thus Fvulgaremay be employed in treatment of cognitive disorderssuch as dementia and Alzheimerrsquos disease as a nootropic andanticholinesterase agent [80]

49 Antihirsutism Activity Idiopathic hirsutism is definedas the occurrence of excessive male pattern hair growth inwomen who have a normal ovulatory menstrual cycle andnormal levels of serum androgens It may be a disorder ofperipheral androgen metabolism Traditionally Foeniculumvulgare has been used as an estrogenic agent It has beenreputed to increase milk secretion promote menstruationfacilitate birth and increase libido On considering aboveaspect Javidnia and his research team evaluated the antihir-sutism activity of ethanolic extract of F vulgare seed againstidiopathic hirsutism by preparing cream containing 1 and 2of fennel extract The efficacy of treatment with the creamcontaining 2 fennel is better than the cream containing 1fennel and these two were more potent than placebo (control

group) The mean values of hair diameter reduction were78 183 and minus05 for patients receiving the creamscontaining 1 2 and 0 (placebo) respectively [78]

410 Estrogenic Properties Since the discovery of the estrusinducing effects of some plant products in 1926 consider-able effort has been devoted towards the characterizationof phytoestrogens including flavonoids isoflavonoids chal-cones coumestans stilbenes lignans saponins and essentialoils [16] F vulgare has estrogen-like activity In male ratstotal concentration of protein was found to be significantlydecreased in testes and in vasa deferentia whereas increasedin seminal vesicles and in prostate gland On the otherhand simultaneous decrease in the activities of acid andalkaline phosphatase in all these regions (except that alka-line phosphatase was unchanged in vasa) due to the oraladministration of acetone extract of F vulgare fruit wasobserved In female rats oral administration of the extract for10 days led to vaginal cornification and oestrus cycle [8] Totalconcentration of nucleic acids and protein as well as the organweights increased in both the tissues namely mammaryglands and oviducts due to the oral administration of acetoneextract (50 150 and 250120583g100 g body wt) of F vulgare seeds[104] Fennel oil was reported to exhibit estrogenic activitypromote menstruation and alleviate the symptoms of femaleclimacteric and increase libido [71] Administration of fenneloil (25 and 50 120583gmL final concentration in the organ bath)failed to exhibit any remarkable effect in uterine contrac-tion While 10 20 and 40 120583gml concentration of fennel oilrevealed significant inhibitory effect against prostaglandinE2 Fennel oil significantly reduces the frequency of uterinecontraction induced by prostaglandin E2 Thus the extractsof F vulgare have strong estrogenic activity [76]

411 Galactogenic Activity Foeniculum vulgare has been usedformillennia to increasemilk secretion [105]Thus F vulgarebelongs to galactagogue substance Structural similarity ofits main constituent anethole to dopamine seems to beresponsible for galactogenic activityDopamine acts to inhibitthe secretion of the milk-producing hormone prolactinAnethole might influence milk secretion by competing withdopamine at the appropriate receptor sites thereby inhibitingthe antisecretory action of dopamine on prolactin [71] It wasreported that anol (demethylated anethole) causes growthof the lobule-alveolar system in the mammary glands ofimmature female rabbits and induces menstruation in miceand other experimental animals Anol also gave positiveresults in the Jadassohn nipple test a test which involvesthe measurement of changes induced in the nipples ofguinea pigs subjected to the cutaneous application of sexhormones However further research suggests that the actualpharmacologically active agents responsible for galactogenicactivity are polymers of anethole such as dianethole andphotoanethole rather than anol or anethole itself [20 76]

412 Expectorant Activity F vulgare seeds stimulate theciliary motility of the respiratory apparatus and enhance the

BioMed Research International 23

external transport of extraneous corpuscles This action sug-gests a use for fennel in treating bronchial and bronchopul-monary afflictions and in particularly polluted environments[106] The volatile oil of F vulgare stimulates the contractionof the smooth muscles of the trachea an action that couldfacilitate the expectoration of mucus bacteria and othercorpuscles extraneous to the respiratory tracts [74]

413 Anticolitic Activity Essential oil of fennel regulates themotility of smooth muscles of the intestine while at thesame time reducing intestinal gas Alone or combined withother plant medicinals Foeniculum vulgare is indicated in thetreatment of spastic gastrointestinal disturbances in someforms of chronic colitis (which resist other treatments) indyspepsias from gastrointestinal atony in dyspepsias withthe sensation of heaviness in the stomach and so forthTheaddition of fennel to preparations containing anthraquinoniccomponents reduces the occurrence of abdominal pain oftenassociated with this type of laxative [73]

414 Antinociceptive Activity Antinociceptive means anysubstance that inhibits nociception which is a physiologicalprocess underlying the sensation of pain Briefly it reducesthe sensitivity to painful stimuli The various extracts ofaerial part of F vulgare namely hexane methylene chlorideethyl acetate and methanolic extract showed remarkableantinociceptive activity against acetic acid induced writhingin mice [68] The methanolic extract of the aerial parts ofF vulgare exhibited the highest antinociceptive activity at adose level of 2000mgkg while the activity exhibited by theethyl acetate extract was at dose level 800mgkgOn the otherhand n-hexane extract (700mgkg) and methylene chlorideextract (500mgkg) exhibited similar antinociceptive activi-ties being less than peripheral antinociceptive reference drug(acetyl salicylic acid) [68]

415 Diuretic Activity A diuretic is any substance thatpromotes the production of urine Briefly it is an agentthat promotes diuresis Diuretics work by promoting theexpulsion of urine (measured as the urine volume [UV]excreted) and urinary sodium (UNa) from the body and thishelps reduce the volume of blood circulating through thecardiovascular system Caceres et al [107] performed a studyin conscious animals and administered a powdered extractof the whole plant (F vulgare) which had no effect on UVor UNa The ethanolic extract of F vulgare fruit revealedexcellent diuretic activity and proves the earlier folk claimof F vulgare which was reported in the United State ofAmerica (Table 5) The fruit extract showed statistically ahighly significant diuretic effect F vulgare induced diuresis(500mgkg dose)was comparable to that of reference diureticagent urea (960mgkg dose) in mice with a urine outputthat was almost double that of the control group Thediuresis was not associated with changes in sodium andorpotassium excretion [108] In another part of the study theauthors showed that Foeniculum vulgare had little effect onthe noradrenalin contractile responses of aortic rings thus

suggesting that it worked mainly as a diuretic and natriureticwith little effect on arterial vascular tone [77]

416 Cardiovascular Activity An aqueous extract of F vul-gare leaves possesses potential cardiovascular action Thiseffect was investigated using pentobarbital-anaesthetisedmale albino Sprague-Dawley rats [75] An intravenousadministration of the lyophilized boiled water extract ofleaves produced a significant dose-related reduction in arte-rial blood pressure without affecting the heart rate or respi-ratory rate On the other hand the nonboiled aqueous extractshowed very little hypotensive activityThe hypotensive effectof the boiling water extract appeared not to be mediated viaadrenergicmuscarinic ganglionic or serotonergic receptorshowever histamine antagonists inhibited the hypotensiveeffect in a dose-related manner [75]

417 Oculohypotensive Activity The aqueous seed extract ofF vulgare demonstrated significant oculohypotensive activityusing water loading and steroid induced glaucoma modelThis extract exhibited 1749 2116 and 2203 reduction ofintraocular pressure in normotensive rabbits at 03 06and 12 (wv) concentrations respectively A maximummean difference of 3120 was observed between vehiclestreated and extracts treated eyes in water loading experi-mental animal model while a maximum mean intraocularpressure lowering of 3129 was observed in steroid inducedmodel of glaucoma Thus the aqueous extract of F vulgarerevealed oculohypotensive activity which was found to be asgood as that of reference standard antiglaucoma drugs calledtimolol [84]

418 Antithrombotic Activity Tognolini et al [55] providedevidence of potent inhibitory activity of essential oil of F vul-gare against platelet aggregation induced byADP arachidonicacid and collagen in guinea pig plasma Similar findingswere reported by Yoshioka and Tamada [109] for aggregationof rabbit platelets by an aromatic factor of fennel oil Theessential oil and anethole (a constituent of oil) of F vulgaretested in vitro in rat aorta with or without endotheliumdisplayed comparable NO-independent vasorelaxant activityat antiplatelet concentrations It supports the safety of Fvulgare that is free from cytotoxic effects Anethole and Fvulgare did not cause cytotoxicity when incubated for 30minupto 300 120583gmL in platelet viability test This concentrationwas largely compatible with those adopted in the functionalin vitro tests In vivo both F vulgare essential oil andanethole orally administered in a subacute treatment to mice(30mgkgday for 5 days) showed significant antithrom-botic activity preventing the paralysis induced by collagen-epinephrine intravenous injection (70 and 83 protectionresp)Thus essential oil and its main component anethole ofF vulgare showed a safe antithrombotic activity in guinea pigplasma that seems due to their broad spectrum antiplateletactivity clot destabilizing effect and vasorelaxant action [55]

419 Antimutagenic Effect Essential oil of F vulgare revealednoteworthy protective effects against genotoxicity in mice

24 BioMed Research International

induced by cyclophosphamide Genotoxicity and cytotoxicitywere assessed by using mice bone marrow chromosomalaberration micronucleus and sperm abnormality assaysrespectively Oral administration of essential oil (1 and2mLkg) significantly inhibited the frequencies of aberrantmetaphases chromosomal aberrations micronuclei forma-tion and cytotoxicity in mouse bone marrow cells inducedby cyclophosphamide and also produced a significant reduc-tion of abnormal sperm and antagonized the reduction ofcyclophosphamide induced superoxide dismutase catalaseand glutathione activities and inhibited increased malondi-aldehyde content in the liver Additionally F vulgare inhibitsthe oxidative stress induced by cyclophosphamide [90]

420 Gastrointestinal Effect Theaqueous extract of F vulgareshowed remarkable antiulcerogenic effect against ethanol-induced gastric lesions in rats It was found that pretreatmentwith aqueous extract significantly reduced ethanol-inducedgastric damageThis effect of aqueous extract was highest andstatistically significant in 300mgkg group comparedwith thecontrol (119875 lt 0001) group of animal Additionally aqueousextract of F vulgare significantly reduced the whole bloodmalondialdehyde levels while significantly increased nitritenitrate ascorbic acid retinol and beta-carotene levels Thusaqueous extract of F vulgare fruit had clearly a protectiveeffect against ethanol-induced gastric mucosal lesion in rats[81]

421 Chemomodulatory Action The chemopreventive effectof different doses of test diet of Foeniculum vulgare seeds wasexamined against 712-dimethylbenz(a)anthracene- (DMBA-) induced skin papillomagenesis and benzo(a)pyrene-[B(a)P-] induced forestomach papillomagenesis at the peri-initiational level in Swiss albino mice Fennel seeds exhibita significant reduction in the skin and the fore-stomachtumor incidence and tumor multiplicity as compared tothe control group Further biochemical assays showeda significant increase in the contentactivities of phase Ienzymes especially in the case of 6 test diet A concomitantincrease in the activities of the phase II enzymes wasobserved with all the doses of test diet under study Asignificant enhancement in the activities of antioxidantenzymes was observed especially at 4 and 6 test diets offennel These findings were indicative of chemopreventivepotential of fennel against carcinogenesis This is the firstreport showing chemopreventive potential of seeds of fennelagainst carcinogenesis [85]

422 Cytoprotection and Antitumor Activity Anethole is theprincipal active component of fennel seeds which has exhib-ited anticancer activity Al-Harbi et al studied the antitumoractivity of anethole against Ehrlich ascites carcinoma inducedin a tumor model in Swiss albino mice The study revealedthat anethole increased survival time reduced tumor weightand reduced the volume and body weight of the Ehrlichascites tumour-bearing mice It also produced a significantcytotoxic effect in the Ehrlich ascites tumour cells in the pawreduced the levels of nucleic acids and malondialdehyde and

increased glutathione concentrations [110] In vitro cytopro-tection activity of methanolic extract of Foeniculum vulgarewas evaluated against normal human blood lymphocytes bymicronucleus assay and antitumor activity against B16F10melanoma cell line by Trypan blue exclusion assay for cellviability Lymphocyte culture treated with 70 methanolicextract of Foeniculum vulgare showed very less percentage ofmicronucleus that is 0006 as compared to standard drugdoxorubicin which showed 0018 micronucleus On theother hand 70methanolic extract of Foeniculum vulgare haspotent antitumor activity at the concentration of 200120583gmLThe results suggest that the Foeniculum vulgare could beconsidered as a natural resource of antitumor agents as wellas cytoprotective to normal cells [11]

423 Cytotoxicity Kaileh and his coworker investigated thecytotoxic effect of organic extracts of 24 selected Palestinianmedicinal plant species The plant selection was based onexisting ethnobotanic information and interviews with localhealers The extracts of the plants under investigation weretested for their potential antitumor (cytotoxic) effect on themurine fibrosarcoma L929sA cells and on the human breastcancer cells MDA-MB231 and MCF7 The extract from Fvulgare presented an IC (50) value at 24 h of 700 plusmn 28 and500plusmn17 120583gmL on L929sA andMCF7 cells respectivelyThenuclear transcription factor NFkappaB or NF120581B regulatesthe expression of various genes They further investigatedthe effect of nine promising plant extracts withheld fromthe first cell viability screening on NF120581B activation Thedichloromethane and methanol (1 1) extract of aerial part ofF vulgare revealed immunomodulatory NF120581B activities [82]Also Berrington and Lall investigated the in vitro cytotoxicityof acetone extracts of F vulgare and other eight medicinalplants against a noncancerous African green monkey kidney(Vero) cell line and an adenocarcinoma cervical cancer(HeLa) cell line [87]

424 Antipyretic Activity F vulgare extract showedantipyretic activity against hyperpyrexia in mice It wasinduced by SC administration of 2mL100 g of a 20aqueous suspension of brewerrsquos yeast As an antipyreticagent ethanolic extract of F vulgare fruit showed a moderateantipyretic activity that was statistically significant after 30and 90min (119875 lt 001) [108]

425 Hypolipidemic Activity The aqueous extract of F vul-gare revealed notable hypolipidemic and antiatherogenicactivity against Triton WR-1339 induced hyperlipidemiain mice Aqueous extract causes significant reduction ofplasma lipid levels that is cholesterol triglycerides LDL-cholesterol and apolipoprotein-B decreased by 40 2361 and 61 respectively and increase in HDL-cholesteroland apolipoprotein A1 by 85 and 58 respectively [88]

426 Hypoglycemic Activity The essential oil of F vulgareexhibits potential hypoglycemic and antioxidant activityagainst streptozotocin induced diabetes in rats Essentialoil (30mgkg body weight) of F vulgare works in the

427 Antispasmodic Activity The antispasmodic activity of25 and 100mLL of alcoholic extract of Foeniculum vulgarealong with other Germanic medicinal plants namelyMelissaofficinalis Rosmarinus officinalisMentha piperitaMatricariachamomilla Carum carvi and Citrus aurantium were testedemploying the guinea pig ileum and using acetylcholine andhistamine as spasmogens An alcoholic extract of the fruits ofFoeniculum vulgare possesses antispasmodic activity whichinhibits the acetylcholine and histamine-induced guineapig ileal contractions in vitro An essential oil which isobtained from the fruits of Foeniculum vulgare 25 120583gmL and10 120583gmL respectively inhibited oxytocin and prostaglandin[72]

428 Apoptotic Activity The apoptotic activities of ethanolextracts from fruits of seven species of Apiaceae familynamely Eryngium planum Archangelica officinalis Pasti-naca sativa Heracleum sibiricum Carum carvi Foenicu-lum vulgare and Levisticum officinale against ML-1mdashhumanacute myeloblastic leukaemia J-4501mdashhuman acute Tcell leukaemia EOLmdashhuman eosinophilic leukaemia HL-60mdashhuman Caucasian promyelocytic leukaemia 1301mdashhuman T cell leukaemia lymphoblast C-8166mdashhuman Tcell leukaemia U-266B1mdashhuman myeloma WICLmdashhumanCaucasian normal B cell and H-9mdashhuman T cell wereinvestigated with the help of Trypan blue assay and AnnexinV fluos assay [86] The ethanol extract from fruit F vulgareshowed the highest mortality in Trypan blue test for J45cell linemdash4 of viable cells and for C8166 cell linemdash100of mortality However the cells of other lines showed thehighest viability HL60mdash60 EOLmdash48 and MLmdash1ndash42The normal cell line H9 and WICL showed 35 and 25of viable cells respectively C8166 cell line and J-45 cell lineshowed the highest level of the apoptotic cells detected byAnnexin V methodmdash100 and 93 respectively Howeverthe cells of two lines HL60 and EOL-1 showed the lowerlevels of apoptotic cellsmdash52 and 60 respectively Highpercentage of apoptotic cells was observed inH9 andWICLmdash76 and 93 respectively [86]

429 Human Liver Cytochrome P450 3A4 Inhibitory ActivityThirteen compounds isolated from the methanolic extract offennel have been found to possess human liver cytochromeP450 3A4 inhibitory activity Among these compounds 5-methoxypsoralen (5-MoP) showed the strongest inhibitionwith an IC50 value of 183120583m and with a mixed type ofinhibition [83]

430 Antiaging Effects Rasul and his coworker developeda base and formulation containing 4 concentrated seedextract of F vulgare This formulation shows notable antiag-ing effect with supporting experimental data related to skinmoisture and transepidermal water loss (TEWL) The basewas insignificant while the formulation showed significanteffects on skin moisture and TEWL The texture parameterenergy showed a significant increase proving that the formu-lation possesses potential antiaging effects [50]

431 Bronchodilatory Effect Ethanol extract and essential oilfrom F vulgare exhibited bronchodilatory activity on con-tracted tracheal chains of guinea pig The potassium channelopening effect of fennel may contribute on its relaxant effecton guinea pig tracheal chains [111] Moreover anethole bearsa striking resemblance to the catecholamines epinephrinenorepinephrine and dopamine This structural similarityappears to be responsible for the various sympathomimeticactivities of F vulgare such as bronchodilatory effect [71]

432 Antioxidant Activities Naturally occurring antioxi-dants can be used to protect human beings from oxidativestress damage [112] Fennel was known as excellent source ofnatural antioxidants and contributed to the daily antioxidantdiet [113]Wild fennel was found to exhibit a free radical scav-enging activity with higher content phenolic and flavonoidthan medicinal and edible fennel and the aerial parts ofthe Italian fennel populations showed the highest DPPHscavenging activity [65] Phenolic compounds of fennelincluding caffeoylquinic acid rosmarinic acid eriodictyol-7-orutinoside quercetin-3-O-galactoside and kaempferol-3-O-glucoside showed antioxidant activities [67] The volatileoil showed strong antioxidant activity in comparison withbutyrated hydroxyanisole and butylated hydroxytolueneEthanol and water extracts of fennel showed less antioxidantactivity compared with essential oil [114]

5 Environmental Application

Foeniculum vulgare that is fennel not only exhibited phar-macological activities but also revealed a few environmentalactivities These activities play a key role in the managementof nematode insect mosquitoes and some harmful larvae ofmalaria producing vector Thus the extracts of F vulgare andisolated biologically active compounds have been evaluatedfor their insecticidal repellent acaricidal larvicidal andnematicidal activity [115ndash119] A brief review on the differenttype of ecofriendly environmental activities as reported onthis plant is summarized below

51 Insecticidal Activities The fruit derived phytoconstitu-ents of F vulgare exhibited prominent insecticidal activi-ties against Sitophilus oryzae Callosobruchus chinensis andLasioderma serricorne This activity was examined usingdirect contact application and fumigation methods Thebiologically active constituents that is phenylpropenes (E)-anethole and estragole and the monoterpene (+)-fenchonewere characterized from Foeniculum fruit By using a filter

26 BioMed Research International

paper diffusion test estragole (0168mg cmminus2) caused 91mortality to S oryzae within 1 day after treatment whereas(+)-fenchone and (E)-anethole gave over 90 mortality at 2and 4 day after treatment respectively

After 2 days of treatment all test compounds (0021mg cmminus2 concentration) revealed potent insecticidal activityagainst C chinensis Whereas after 1 day of treatment (E)-anethole (0105mg cmminus2) gave 100mortality of L serricornewhereas 90 and 60 mortality at 4 day after treatment wasachieved with estragole and (+)-fenchone respectively In afumigation test the compounds were much more effectiveagainst adults of S oryzae C chinensis and L serricorne inclosed cups than in open ones indicating that the insecticidalactivity of test compounds was largely attributable to fumi-gant action As naturally occurring insect-control agents theF vulgare fruit-derived materials described could be usefulfor managing field populations of S oryzae C chinensis andL serricorne [116]

52 Acaricidal Activity Fennel oil shows significant acaricid-al activity againstDermatophagoides farinae andDermatoph-agoides pteronyssinus (+)-fenchone and p-anisaldehyde aremajor constituents of fruit oil of F vulgare P-anisaldehydewas the most toxic compound against D farinae and is muchmore effective compared with benzyl benzoate thymol andestragol [118]

53 Repellent Activity The methanolic extract of fruits ofF vulgare was spectroscopically characterized for the pres-ence of biologically active constituents called (+)-fenchoneand (E)-9-octadecenoic acid The repellent activity of theseconstituents was tested against hungry Aedes aegypti femaleswith the help of skin and patch tests and compared withthat of the commercial repellent agent called NN-diethyl-m-toluamide (DEET) and (Z)-9-octadecenoic acid In askin test with female mosquitoes (+)-fenchone and (Z)-9-octadecenoic acid (04mgcm2) exhibitedmoderate repellentactivity at 30min after treatment whereas DEET providedgt1 h of protection against adult mosquitoes at (02mgcm2)Thus (+)-Fenchone and (E)-9-octadecenoic acid are poten-tial mosquito repellent agents or lead compounds [117]

54 Larvicidal Activity Plant extracts and oils may act asalternatives to conventional pesticides for malaria vectorcontrol By considering this aspect Sedaghat et al [119] inves-tigated the larvicidal activity of essential oils of three plantsof Apiaceae family against malaria vector called Anophe-les stephensi The larvicidal activity was evaluated againstlaboratory-reared larvae by standard method of WHO TheF vulgare oil was the most effective against A stephensiwith LC(50) and LC(90) values of 2010 and 4451 ppmrespectively [119] Additionally the essential oil extracts fromleaves flowers and roots of F vulgare exhibit noticeablelarvicidal activity against fourth-instar larvae of themosquitoCulex pipiens molestus Terpineol and 18-cineole content of Fvulgare are the most effective phytoconstituent against Culexpipiens molestus bites offering complete protection for 16 and2 h respectively [120] Recently Zoubiri et al [57] reported

the larvicidal activity of essential oil of fennel seed againstCulex pipiensmosquitoThus F vulgare can serve as a naturallarvicidal agent

55 Nematicidal Activity Oka et al investigated the in vitronematicidal activity of essential oils extracted from 27 spicesand aromatic plants in pot experiments Twelve of thetwenty-seven essential oils immobilized more than 80 ofjuveniles of the root-knot nematodeMeloidogyne javanica ata concentration of 1000 120583Lliter At this concentration mostof these oils also inhibited nematode hatching Essential oilsof Carum carvi Foeniculum vulgare Mentha rotundifoliaand Mentha spicata showed the highest nematicidal activityamong the in vitro tested oils In 3-liter pot experimentsnematicidal activity of the essential oils and their componentswas confirmed at 200 and 150mgkg respectivelyThe resultssuggest that the essential oils and theirmain componentsmayserve as nematicides [115]

6 Toxicity

The long history of ethnomedicinal application with noreports of any serious side effects suggests that F vulgarecould be considered as safe Inmost toxicity experiments car-ried out on F vulgare no sign of toxicity was observed Shahand his coworker in 1991 investigated the detailed toxicityaccount of ethanolic extract of fennel fruit in experimentalmice with respect to acute and 90 days longer term toxicity[121] In experimentation Shah and his coworker observedthe general symptoms of toxicity and mortality for only 24 hin acute toxicity Whereas in another part of toxicity theystudied the effect of fennel extract on mice with 90 dayslong term treatment Acute toxicity of ethanolic extract of Fvulgarewas assessed in 35mice by using three concentrationsnamely 05 1 and 3 gkg body weight In this investigation Fvulgare exhibited no signs of toxicity and no mortality wasobserved upto the dose level 3 gkg body weight In case oflonger term toxicity ethanolic extract of F vulgare (100mgkgbody weightday) was given in drinking water of animals(30 male and 30 female mice) All external morphologicalhaematological and spermatogenic changes in addition tobody and vital organ weights were recorded The extractcaused no significant chronic mortality as compared tocontrols during this investigation The treated male micegained significant weight during chronic treatment while aloss or no significant change in weight was noticed in thefemale mice treated with the same extract The extracts didnot show spermatotoxic effects Thus Shah and his coworkerconcluded that fennel extract is safe based on both acuteandor long term toxicity studies [121] Additionally the plantextract in doses of 05 1 and 3 gkg (orally) did not causeany deaths These doses do not show any type of toxicityagainst several parameters tested namely locomotor activitybizarre reactions sensitivity to sound social interaction tailposture aggressive behaviour ataxia paralysis convulsionstremors prostration exophthalmos pupil size defecationsalivation urination pattern of respiration nasal dischargecyanosis and piloerection Exceptionally only the 3 gkg dose

BioMed Research International 27

showed signs of reduced locomotor activity and piloerec-tion Otherwise all other parameters were negative [108]In another experiment of acute toxicity different solventextracts namely n-hexane methylene chloride ethyl acetateand methanol extracts of F vulgare upto 55 gkg concentra-tion did not revealed any kind of toxicity in mice LD50being 675 110 692 and 15 gkg for n-hexane methylenechloride ethyl acetate and methanol extracts respectively[68] The plant extract of F vulgare was administered orallyat a dose of 100 200 400 600 800 1000 and 2000mgkgof body weight of mice Each group of animals was undervisual observation for 10 days for the external behavior ofneurological toxicity created by plant extract Even the micereceiving highest dose of F vulgare extract did not show anymortality or toxicity demonstrating the safety profile of theplant extract [89]

The acute oral 50 LD50 for anethole in rats was foundto be 2090mgkg Repeated doses of one-third the LD50 ofanethole (695mgkg) given to rat caused mild liver lesionsIt would therefore appear that in normal therapeutic dosagesanethole would have minimal hepatotoxicity When anetholewas fed to rats daily for one year as 025 of the dietno hepatic damage was seen [122] The acute oral LD50 ofessential oil in rats is 1326mgkg [76] The use of F vulgareessential oil as a remedy for control of primary dysmenorrheaincreases concern about its potential teratogenicity due toits estrogen like activity Evaluation of teratogenicity ofessential oil using limb bud mesenchymal cells showed thatthe essential oil may have toxic effect on fetal cells butthere was no evidence of teratogenicity upto concentrationof 93mgmL of culture medium [123] The overall toxicitystudies carried out on F vulgare accounts for its safety at therecommended therapeutic doses

7 Conclusions

The available scientific research on Foeniculum vulgarehas shown that it is an important medicinal plant used ina wide range of ethnomedical treatments especially forabdominal pains antiemetic aperitif arthritis cancer colicin children conjunctivitis constipation depurative diarrheadieresis emmenagogue fever flatulence gastralgia gastritisinsomnia irritable colon kidney ailments as a laxativeleucorrhoea liver pain mouth ulcer and stomachache Thisplant has been in use for a long period of time withoutany documented serious adverse effects Studies carriedout in the past and present indicate that fennel possessesdiverse health benefits and are an important constituentof food Studies have shown that various extracts offennel possess a range of pharmacological actions such asantiaging antiallergic anticolitic antihirsutism anti-inflam-matory antimicrobial and antiviral antimutagenic antino-ciceptive antipyretic antispasmodic antistress antithromb-otic anxiolytic apoptotic cardiovascular chemomodulatoryaction cytoprotection and antitumor cytotoxicity diureticestrogenic properties expectorant galactogenic gastrointes-tinal effect hepatoprotective human liver cytochrome P4503A4 inhibitory hypoglycemic hypolipidemic memory-en-hancing property nootropic and oculohypotensive activity

supporting its traditional use However the most prominentand the well studied effects are the antimicrobial andantioxidant effects of essential oil of fennel in differentexperimental models The observed health benefits may becredited to the presence of the various phytochemicals likevolatile compounds flavonoids phenolic compounds fattyacids and amino acids

Fennel also contains mineral and trace elements likealuminum barium calcium cadmium cobalt chromiumcopper ironmagnesiummanganese nickel lead strontiumand zinc [124] fat soluble vitamins such as vitamins A Eand K water soluble vitamins like ascorbic acid thiamineriboflavin niacin and pyridoxine essential amino acidslike leucine isoleucine phenylalanine and tryptophane maycontribute to the myriad health beneficial effects at least inpart

Most of the pharmacological studies were conductedusing uncharacterized crude extracts of fennel It is difficultto reproduce the results of these studies and pinpoint thebioactive compounds Hence there is a need for chemi-cal standardization and bioactivity-guided identification ofbioactive compounds Among several classes of chemicalconstituents identified in fennel volatile components of fen-nel essential oil and phenolic compounds are assumed to bethe main bioactive compounds responsible for the majorityof its pharmacological effects However the vast traditionaluse and proven pharmacological activities of fennel indicatethat an immense scope still exists for its chemical explorationFuture studies should be focused on validating the mecha-nism of action responsible for the various beneficial effectsand also on understanding which plant based compounds areresponsible for the reported effectsThe required informationwhen available will enhance our knowledge and appreciationfor the use of fennel in our daily diet Also the outcomeof such chemical studies may further expand its existingtherapeutic potential

Thus there are many areas of research related to thisplant that need to be further explored to fully recognize itsbeneficial effects for society Factors such as geographical andseasonal variation play an important role in the authentica-tion of the chemical constituents responsible for the activitywhich also can be an area of interest Thus it is incumbenton researchers to fill the huge gap of insufficient knowledgeand create awareness among pharmacologists as well as inves-tigators towards providing better medicinal value derivedfrom this plant This can be fulfilled only by generatinginterest among the research community through writing ofcritical appraisals (paper) and extending the interdisciplinaryresearch area to focused studies on Foeniculum vulgare

Turkish [51 56] Serbian [52] Indian [54] and Chinese [53]fennels The hexane extracts of fennel were analyzed by GC-MS and 78 compounds were identified from these extractsthe major compounds were identified as 13-benzenediol 1-methoxycyclohexene o-cymene sorbic acid 2-hydroxy-3-methyl-2-cyclopenten-1-one estragole limonene-10-ol and3-methyl-2-cyclopenten-1-one [63] Diao et al [64] identifya total of 28 components by GC and GCMS from fenneloil representing 958 of the total amount Trans-Anethole(6853) a phenylpropanoid was found to be the maincomponent followed by estragole (1042) with limonene(624) fenchone (545) and others as minor components

32 Flavonoids Flavonoids are generally considered as animportant category of antioxidants in the human dietFlavonoids are abundant in the plants of Apiaceae family Ithas been reported that the presence of flavonol glycosidesin fennel species is related to its morphological hetero-geneity and variation Total flavonoid content of hydroal-coholic extracts is about 123 plusmn 018mgg Flavonoids likeeriodictyol-7-rutinoside quercetin-3-rutinoside and ros-marinic acid have been isolated from F vulgare [65]Amongst the flavonoids present in F vulgare the most preva-lent are quercetin-3-glucuronide isoquercitrin quercetin-3-arabinoside kaempferol-3-glucuronide and kaempferol-3-arabinoside and isorhamnetin glucoside [66] Quercetin-3-O-galactoside kaempferol-3-O-rutinoside and kaempferol-3-O-glucoside have also been reported to occur in the aque-ous extract of F vulgare [67] The flavonoids like isorham-netin 3-O-120572-rhamnoside quercetin and kaempferol werealso isolated from the ethyl acetate extract whereas quercetin3-O-rutinoside kaempferol 3-O-rutinoside and quercetin3-O-120573-glucoside were isolated from the methanol extractThese flavonoids exhibit remarkable antinociceptive and anti-inflammatory activity [68] Further quercetin rutin andisoquercitrin were reported to have the immunomodulatoryactivities [69]

33 Phenolic Compounds There has been a growing interestin phenolic components of fruits and vegetables which maypromote human health or lower the risk of disease Aqueous

extract of fennel fruits are rich in phenolic compoundsMany of them have antioxidant activities and hepatopro-tective properties The phenolic compounds present in Fvulgare are considered to be associated with the preventionof diseases possibly induced by oxidative stress such ascardiovascular diseases cancer and inflammation Thesephenolic compounds have received tremendous attentionamong nutritionists food scientists and consumers dueto their role in human health Fennel has been reportedto contain hydroxyl cinnamic acid derivatives flavonoidglycosides and flavonoid aglycones [67] The methanolicextract of fennel seeds contains rosmarinic acid chlorogenicacids as major phenolic compounds (149 and 68 resp)and quercetin and apigenin as themajor flavonoids (171 and125 resp) Also the total phenolic compounds in fennelmethanol extract were higher than the flavonoid compounds[23] F vulgare has been reported to contain phenolic acidslike 3-O-caffeoylquinic acid 4-O-caffeoylquinic acid 5-O-caffeoylquinic acid 13-O-di-caffeoylquinic acid 14-O-di-caffeoylquinic acid and 15-O-di-caffeoylquinic acid [65]Two compounds A and B were isolated and character-ized for the first time from the wild fennel and identi-fied as 34-dihydroxyphenethylalchohol-6-O-caffeoyl-120573-D-glucopyranoside and 3101584081015840-binaringenin respectively Thetotal phenolic and flavonoid contents ofwild fennel (24 and12 resp) were less as compared to cultivated fennel (31and 16 resp) [70]

4 Pharmacological Activities

Foeniculum vulgare is officially noted in Ayurvedic Pharma-copoeia as an important part of polyherbal formulations inthe treatment of different diseases and disorders A numberof biological-pharmacological studies have been undertakento evaluate the indigenous uses of F vulgare Few extracts of Fvulgare and isolated compounds have been evaluated for sev-eral activities namely antiaging antiallergic anticolitic anti-hirsutism anti-inflammatory antimicrobial and antiviralantimutagenic antinociceptive antipyretic antispasmodic

methanolic fruit extract of F vulgare inhibited the growthof Staphylococcus aureus and Bacillus pumilus with 1127 and1267mm zone of inhibition respectively [7]

Several studies indicating the antifungal effect of Fvulgare along with antibacterial effect are also reported inthe literature Martins et al [94] investigated the antibacterialand antifungal effects of three essential oils of Portugueseplants namely Foeniculum vulgareMentha spicata and Ros-marinus officinalis against Staphylococcus aureus Escherichiacoli Klebsiella pneumonia Pseudomona aeruginosa Staphy-lococcus epidermidis Candida albicans and phytopathogenic

diseases [97] In an in vitro study aqueous and alcoholicseed extracts of F vulgare exhibited inhibitory effect againstAlternaria alternata Mucor rouxii and Aspergillus flavus[98] Interestingly aqueous seed extract of F vulgare showedstrongest antifungal activity as compared to reference fungi-cidal agent that is griseofulvin [99]

All of the above mentioned studies were carried outon the crude extracts and it is difficult to pinpoint theactive antimicrobial metabolite A phenylpropanoid deriva-tive called dillapional characterized from F vulgare stem wasfound to be an antimicrobial constituent with MIC values of125 250 and 125 against Bacillus subtilis Aspergillus nigerand Cladosporium cladosporioides respectively A coumarinderivative scopoletin was also isolated as a marginallyantimicrobial agent [100] The characterization of sevendifferent types of oxygenatedmonoterpenes frommethylene

chloride crude extract of F vulgare [101] suggested thatthe crude extract containing monoterpenes could be a newmedicinal resource for antibacterial agents

A total of 78 compounds were identified from theactive antimycobacterial fraction of F vulgare with thehelp of gas chromatography-mass spectra (GC-MS) Outof these twenty compounds were tested against one sensi-tive and three MDR strains of Mycobacterium tuberculosisusing the Alamar Blue microassay Compounds that showedsome degree of antimycobacterial activity against all strainstested were the following linoleic acid (MIC 100 120583gmL)oleic acid (MIC 100 120583gmL) 13-benzenediol (MIC 100ndash200120583gmL) undecanal (MIC 50ndash200120583gmL) and 24-undecadienal (MIC 25ndash50120583gmL) 24-Undecadienal wasthe most active compound against multidrug resistant Mtuberculosis speciesThus the dietary intake of F vulgaremaylower the risk ofM tuberculosis infection [63]

Orhan et al [5] studied the antiviral activity of theessential oil of fruit sample of F vulgare along with 12other Turkish medicinal plants against the DNA virusHerpessimplex type-1 (HSV-1) and the RNA virus parainfluenzatype-3 (PI-3) Most of the oils and compounds displayedstrong antiviral effects against HSV-1 ranging between 08and 0025 120583gmL However the samples tested were lesseffective against PI-3 with results ranging between 16 and02 120583gmL Only the essential oils of Anethum graveolensFoeniculum vulgare (fully mature) Mentha piperita Menthaspicata Ocimum minutiflorum Ocimum vulgaris and Sat-ureja cuneifolia inhibited this virus significantly

All these literature findings validated the traditional usesof Foeniculum vulgare in infectious disorders like abdomi-nal pains antiemetic arthritis conjunctivitis constipationdepurative diarrhea dieresis fever flatulence gastralgia gas-tritis insomnia irritable colon mouth ulcer stomachacherespiratory disorders skin diseases and so forth There isalways a need for new antimicrobial agents due to rapiddevelopment of resistance Bioactive metabolites of F vulgaremay be a potential source for new antimicrobial agents

42 Anti-Inflammatory Activity Oral administration ofmethanol extract of F vulgare fruit to rat and mice exhibitedinhibitory effects against acute and subacute inflammatorydiseases The anti-inflammatory activity of methanol extractwas evaluated by using three screening protocols namelycarrageenan-induced paw edema arachidonic acid-inducedear edema and formaldehyde-induced arthritis Theseare widely used for testing nonsteroidal anti-inflammatorydrugs For acute inflammationmethanol extract (200mgkg)exhibits significant inhibition of paw edema (69) inducedby carrageenan injection as compared to the control groupof animals Methanol extract of F vulgare also inhibitsear-edema (70) induced by arachidonic acid in mice Thelevel of serum transaminase aspartate aminotransferase(AST) and alanine aminotransferase (ALT) significantlyincreases in the presence of methanolic extract of F vulgareon inflammation induced by formaldehyde as comparedto control group The assessment of the level of AST and

ALT provides a good and simple tool to measure the anti-inflammatory activity of the target compounds [102] Theseoverall results seem to suggest that F vulgare FME mayact on both the cyclooxygenase and lipoxygenase pathways[79]

43 Antiallergic Activity Methanolic extract of F vulgarefruit showed significant inhibitory effect on DNFB- (24-dinitrofluorobenzene-) induced delayed type hypersensitiv-ity after oral administration of 200mgkg once a day for7 days The inhibitory effect on immunologically inducedswelling suggests the possible immunosuppressive propertiesof F vulgare [79]

44 Hepatoprotective Activity Essential oil of F vulgareseeds revealed a potent hepatoprotective effect against acutehepatotoxicity produced by carbon tetrachloride in ratsOral administration of F vulgare essential oil decreases thelevels of serum aspartate aminotransferase (AST) alanineaminotransferase (ALT) alkaline phosphatase (ALP) andbilirubin as compared to the control group Ozbek et alsuggest that the constituents (d-limonene and 120573-myrcene) ofessential oil may have played a key role in the protection ofliver from CCl

4toxicity [9]

45 Anxiolytic Activity Anxiety is the unpleasant feeling offear and concern When anxiety becomes excessive it maybe considered as an anxiety disorder Anxiolytic fennel isa drug used for the treatment of anxiety and its relatedpsychological and physical symptoms Naga Kishore et al[89] investigated the anxiolytic activity of ethanolic extract ofF vulgare fruit with the help of elevated plus maze rota rodopen field test and whole board models The 100 to 200mgdose of extract per kg of body weight of animal revealedsignificant activity when compared to reference anxiolyticdrug called diazepam (1mgkg) Thus fennel extract maypossess anxiolytic activity supporting its traditional claimabout anxiolytic activity reported in 19th edition of Pharma-cology and Pharmacotherapeutics by Sathodkar Bhandarkarand Rege

46 Antistress Activity Drug and food of natural originplay a significant role in public healthcare systems and arebeing investigated as remedies for a number of stress-relateddisorders [103]Thewhole plant extract of F vulgare exhibitednotable antistress effect against stress induced by forcefulswimming of test animals The key parameters that isurinary levels of vanillyl mandelic acid (VMA) and ascorbicacid in rats were used to evaluate antistress activity Theplant extract (50 100 and 200mgkg body weight) showeda significant improvement in urinary levels of VMA (119875 lt0001) and ascorbic acid excretion levels (119875 lt 0001) in testanimals when compared to the normal basal levels in controlgroup of animalsThus the extract of entire plant of F vulgareacts as an antistress agent [13]

47 Memory-Enhancing Property There are a number ofplants whose consumption is believed to enhance memory

22 BioMed Research International

and intelligence These were usually given to children as partof their food F vulgaris an ayurvedic rasayana (mixture)possessing multiple neuropharmacological activities Theantidepressant activity of fennel has been well documentedin ethnomedicine The whole plants extract (50 100 and200mgkg) of F vulgare exhibited memory-enhancing effectagainst scopolamine-induced amnesic rats This experimentwas evaluated by conditioned avoidance response (CAR)technique The CAR of rats administered with the extractincreased gradually to 95 over 7 to 12 days The acquisition(time to achieve 95 CAR) for rats administered with theextract was dose- and time-dependent compared to controlgroup which took 12 days for acquisition The percentavoidance was always higher in the extract-treated groupsas compared to control group Animals receiving 200mgkgbody weight of the extract took ten days while groups treatedwith 100 and 50mgkg doses of the extract required elevenand twelve days respectively to reach the point of acquisitionAdministration of scopolamine produced amnesia as seenfrom reduction in the observed CAR Amnesia was greaterin the control group than in extract-treated groups How-ever continued treatment with F vulgare produced betterretention and recovery in a dose-dependent manner thanthe vehicle-treated animals Recovery from scopolamine-induced amnesia in the extract-treated groups took 3ndash5 dayswhen compared to normal (control) group which took over6 days This overall progress suggests that F vulgare extractpossesses memory-enhancing property [13]

48 Nootropic Activity Alzheimerrsquos disease is a neurode-generative disorder associated with a decline in cognitiveabilities Dementia is one of the age-related mental problemsand a characteristic symptom of Alzheimerrsquos disease Thereis some evidence in favor of use of F vulgare for the treat-ment of cognitive disorders like dementia and Alzheimerrsquosdisease Methanol extract of the whole plant of F vul-gare administered for eight successive days ameliorated theamnesic effect of scopolamine and aging-induced memorydeficits inmiceThis extract increased step-down latency andacetylcholinesterase inhibition in mice significantly Thus Fvulgaremay be employed in treatment of cognitive disorderssuch as dementia and Alzheimerrsquos disease as a nootropic andanticholinesterase agent [80]

49 Antihirsutism Activity Idiopathic hirsutism is definedas the occurrence of excessive male pattern hair growth inwomen who have a normal ovulatory menstrual cycle andnormal levels of serum androgens It may be a disorder ofperipheral androgen metabolism Traditionally Foeniculumvulgare has been used as an estrogenic agent It has beenreputed to increase milk secretion promote menstruationfacilitate birth and increase libido On considering aboveaspect Javidnia and his research team evaluated the antihir-sutism activity of ethanolic extract of F vulgare seed againstidiopathic hirsutism by preparing cream containing 1 and 2of fennel extract The efficacy of treatment with the creamcontaining 2 fennel is better than the cream containing 1fennel and these two were more potent than placebo (control

group) The mean values of hair diameter reduction were78 183 and minus05 for patients receiving the creamscontaining 1 2 and 0 (placebo) respectively [78]

410 Estrogenic Properties Since the discovery of the estrusinducing effects of some plant products in 1926 consider-able effort has been devoted towards the characterizationof phytoestrogens including flavonoids isoflavonoids chal-cones coumestans stilbenes lignans saponins and essentialoils [16] F vulgare has estrogen-like activity In male ratstotal concentration of protein was found to be significantlydecreased in testes and in vasa deferentia whereas increasedin seminal vesicles and in prostate gland On the otherhand simultaneous decrease in the activities of acid andalkaline phosphatase in all these regions (except that alka-line phosphatase was unchanged in vasa) due to the oraladministration of acetone extract of F vulgare fruit wasobserved In female rats oral administration of the extract for10 days led to vaginal cornification and oestrus cycle [8] Totalconcentration of nucleic acids and protein as well as the organweights increased in both the tissues namely mammaryglands and oviducts due to the oral administration of acetoneextract (50 150 and 250120583g100 g body wt) of F vulgare seeds[104] Fennel oil was reported to exhibit estrogenic activitypromote menstruation and alleviate the symptoms of femaleclimacteric and increase libido [71] Administration of fenneloil (25 and 50 120583gmL final concentration in the organ bath)failed to exhibit any remarkable effect in uterine contrac-tion While 10 20 and 40 120583gml concentration of fennel oilrevealed significant inhibitory effect against prostaglandinE2 Fennel oil significantly reduces the frequency of uterinecontraction induced by prostaglandin E2 Thus the extractsof F vulgare have strong estrogenic activity [76]

411 Galactogenic Activity Foeniculum vulgare has been usedformillennia to increasemilk secretion [105]Thus F vulgarebelongs to galactagogue substance Structural similarity ofits main constituent anethole to dopamine seems to beresponsible for galactogenic activityDopamine acts to inhibitthe secretion of the milk-producing hormone prolactinAnethole might influence milk secretion by competing withdopamine at the appropriate receptor sites thereby inhibitingthe antisecretory action of dopamine on prolactin [71] It wasreported that anol (demethylated anethole) causes growthof the lobule-alveolar system in the mammary glands ofimmature female rabbits and induces menstruation in miceand other experimental animals Anol also gave positiveresults in the Jadassohn nipple test a test which involvesthe measurement of changes induced in the nipples ofguinea pigs subjected to the cutaneous application of sexhormones However further research suggests that the actualpharmacologically active agents responsible for galactogenicactivity are polymers of anethole such as dianethole andphotoanethole rather than anol or anethole itself [20 76]

412 Expectorant Activity F vulgare seeds stimulate theciliary motility of the respiratory apparatus and enhance the

BioMed Research International 23

external transport of extraneous corpuscles This action sug-gests a use for fennel in treating bronchial and bronchopul-monary afflictions and in particularly polluted environments[106] The volatile oil of F vulgare stimulates the contractionof the smooth muscles of the trachea an action that couldfacilitate the expectoration of mucus bacteria and othercorpuscles extraneous to the respiratory tracts [74]

413 Anticolitic Activity Essential oil of fennel regulates themotility of smooth muscles of the intestine while at thesame time reducing intestinal gas Alone or combined withother plant medicinals Foeniculum vulgare is indicated in thetreatment of spastic gastrointestinal disturbances in someforms of chronic colitis (which resist other treatments) indyspepsias from gastrointestinal atony in dyspepsias withthe sensation of heaviness in the stomach and so forthTheaddition of fennel to preparations containing anthraquinoniccomponents reduces the occurrence of abdominal pain oftenassociated with this type of laxative [73]

414 Antinociceptive Activity Antinociceptive means anysubstance that inhibits nociception which is a physiologicalprocess underlying the sensation of pain Briefly it reducesthe sensitivity to painful stimuli The various extracts ofaerial part of F vulgare namely hexane methylene chlorideethyl acetate and methanolic extract showed remarkableantinociceptive activity against acetic acid induced writhingin mice [68] The methanolic extract of the aerial parts ofF vulgare exhibited the highest antinociceptive activity at adose level of 2000mgkg while the activity exhibited by theethyl acetate extract was at dose level 800mgkgOn the otherhand n-hexane extract (700mgkg) and methylene chlorideextract (500mgkg) exhibited similar antinociceptive activi-ties being less than peripheral antinociceptive reference drug(acetyl salicylic acid) [68]

415 Diuretic Activity A diuretic is any substance thatpromotes the production of urine Briefly it is an agentthat promotes diuresis Diuretics work by promoting theexpulsion of urine (measured as the urine volume [UV]excreted) and urinary sodium (UNa) from the body and thishelps reduce the volume of blood circulating through thecardiovascular system Caceres et al [107] performed a studyin conscious animals and administered a powdered extractof the whole plant (F vulgare) which had no effect on UVor UNa The ethanolic extract of F vulgare fruit revealedexcellent diuretic activity and proves the earlier folk claimof F vulgare which was reported in the United State ofAmerica (Table 5) The fruit extract showed statistically ahighly significant diuretic effect F vulgare induced diuresis(500mgkg dose)was comparable to that of reference diureticagent urea (960mgkg dose) in mice with a urine outputthat was almost double that of the control group Thediuresis was not associated with changes in sodium andorpotassium excretion [108] In another part of the study theauthors showed that Foeniculum vulgare had little effect onthe noradrenalin contractile responses of aortic rings thus

suggesting that it worked mainly as a diuretic and natriureticwith little effect on arterial vascular tone [77]

416 Cardiovascular Activity An aqueous extract of F vul-gare leaves possesses potential cardiovascular action Thiseffect was investigated using pentobarbital-anaesthetisedmale albino Sprague-Dawley rats [75] An intravenousadministration of the lyophilized boiled water extract ofleaves produced a significant dose-related reduction in arte-rial blood pressure without affecting the heart rate or respi-ratory rate On the other hand the nonboiled aqueous extractshowed very little hypotensive activityThe hypotensive effectof the boiling water extract appeared not to be mediated viaadrenergicmuscarinic ganglionic or serotonergic receptorshowever histamine antagonists inhibited the hypotensiveeffect in a dose-related manner [75]

417 Oculohypotensive Activity The aqueous seed extract ofF vulgare demonstrated significant oculohypotensive activityusing water loading and steroid induced glaucoma modelThis extract exhibited 1749 2116 and 2203 reduction ofintraocular pressure in normotensive rabbits at 03 06and 12 (wv) concentrations respectively A maximummean difference of 3120 was observed between vehiclestreated and extracts treated eyes in water loading experi-mental animal model while a maximum mean intraocularpressure lowering of 3129 was observed in steroid inducedmodel of glaucoma Thus the aqueous extract of F vulgarerevealed oculohypotensive activity which was found to be asgood as that of reference standard antiglaucoma drugs calledtimolol [84]

418 Antithrombotic Activity Tognolini et al [55] providedevidence of potent inhibitory activity of essential oil of F vul-gare against platelet aggregation induced byADP arachidonicacid and collagen in guinea pig plasma Similar findingswere reported by Yoshioka and Tamada [109] for aggregationof rabbit platelets by an aromatic factor of fennel oil Theessential oil and anethole (a constituent of oil) of F vulgaretested in vitro in rat aorta with or without endotheliumdisplayed comparable NO-independent vasorelaxant activityat antiplatelet concentrations It supports the safety of Fvulgare that is free from cytotoxic effects Anethole and Fvulgare did not cause cytotoxicity when incubated for 30minupto 300 120583gmL in platelet viability test This concentrationwas largely compatible with those adopted in the functionalin vitro tests In vivo both F vulgare essential oil andanethole orally administered in a subacute treatment to mice(30mgkgday for 5 days) showed significant antithrom-botic activity preventing the paralysis induced by collagen-epinephrine intravenous injection (70 and 83 protectionresp)Thus essential oil and its main component anethole ofF vulgare showed a safe antithrombotic activity in guinea pigplasma that seems due to their broad spectrum antiplateletactivity clot destabilizing effect and vasorelaxant action [55]

419 Antimutagenic Effect Essential oil of F vulgare revealednoteworthy protective effects against genotoxicity in mice

24 BioMed Research International

induced by cyclophosphamide Genotoxicity and cytotoxicitywere assessed by using mice bone marrow chromosomalaberration micronucleus and sperm abnormality assaysrespectively Oral administration of essential oil (1 and2mLkg) significantly inhibited the frequencies of aberrantmetaphases chromosomal aberrations micronuclei forma-tion and cytotoxicity in mouse bone marrow cells inducedby cyclophosphamide and also produced a significant reduc-tion of abnormal sperm and antagonized the reduction ofcyclophosphamide induced superoxide dismutase catalaseand glutathione activities and inhibited increased malondi-aldehyde content in the liver Additionally F vulgare inhibitsthe oxidative stress induced by cyclophosphamide [90]

420 Gastrointestinal Effect Theaqueous extract of F vulgareshowed remarkable antiulcerogenic effect against ethanol-induced gastric lesions in rats It was found that pretreatmentwith aqueous extract significantly reduced ethanol-inducedgastric damageThis effect of aqueous extract was highest andstatistically significant in 300mgkg group comparedwith thecontrol (119875 lt 0001) group of animal Additionally aqueousextract of F vulgare significantly reduced the whole bloodmalondialdehyde levels while significantly increased nitritenitrate ascorbic acid retinol and beta-carotene levels Thusaqueous extract of F vulgare fruit had clearly a protectiveeffect against ethanol-induced gastric mucosal lesion in rats[81]

421 Chemomodulatory Action The chemopreventive effectof different doses of test diet of Foeniculum vulgare seeds wasexamined against 712-dimethylbenz(a)anthracene- (DMBA-) induced skin papillomagenesis and benzo(a)pyrene-[B(a)P-] induced forestomach papillomagenesis at the peri-initiational level in Swiss albino mice Fennel seeds exhibita significant reduction in the skin and the fore-stomachtumor incidence and tumor multiplicity as compared tothe control group Further biochemical assays showeda significant increase in the contentactivities of phase Ienzymes especially in the case of 6 test diet A concomitantincrease in the activities of the phase II enzymes wasobserved with all the doses of test diet under study Asignificant enhancement in the activities of antioxidantenzymes was observed especially at 4 and 6 test diets offennel These findings were indicative of chemopreventivepotential of fennel against carcinogenesis This is the firstreport showing chemopreventive potential of seeds of fennelagainst carcinogenesis [85]

422 Cytoprotection and Antitumor Activity Anethole is theprincipal active component of fennel seeds which has exhib-ited anticancer activity Al-Harbi et al studied the antitumoractivity of anethole against Ehrlich ascites carcinoma inducedin a tumor model in Swiss albino mice The study revealedthat anethole increased survival time reduced tumor weightand reduced the volume and body weight of the Ehrlichascites tumour-bearing mice It also produced a significantcytotoxic effect in the Ehrlich ascites tumour cells in the pawreduced the levels of nucleic acids and malondialdehyde and

increased glutathione concentrations [110] In vitro cytopro-tection activity of methanolic extract of Foeniculum vulgarewas evaluated against normal human blood lymphocytes bymicronucleus assay and antitumor activity against B16F10melanoma cell line by Trypan blue exclusion assay for cellviability Lymphocyte culture treated with 70 methanolicextract of Foeniculum vulgare showed very less percentage ofmicronucleus that is 0006 as compared to standard drugdoxorubicin which showed 0018 micronucleus On theother hand 70methanolic extract of Foeniculum vulgare haspotent antitumor activity at the concentration of 200120583gmLThe results suggest that the Foeniculum vulgare could beconsidered as a natural resource of antitumor agents as wellas cytoprotective to normal cells [11]

423 Cytotoxicity Kaileh and his coworker investigated thecytotoxic effect of organic extracts of 24 selected Palestinianmedicinal plant species The plant selection was based onexisting ethnobotanic information and interviews with localhealers The extracts of the plants under investigation weretested for their potential antitumor (cytotoxic) effect on themurine fibrosarcoma L929sA cells and on the human breastcancer cells MDA-MB231 and MCF7 The extract from Fvulgare presented an IC (50) value at 24 h of 700 plusmn 28 and500plusmn17 120583gmL on L929sA andMCF7 cells respectivelyThenuclear transcription factor NFkappaB or NF120581B regulatesthe expression of various genes They further investigatedthe effect of nine promising plant extracts withheld fromthe first cell viability screening on NF120581B activation Thedichloromethane and methanol (1 1) extract of aerial part ofF vulgare revealed immunomodulatory NF120581B activities [82]Also Berrington and Lall investigated the in vitro cytotoxicityof acetone extracts of F vulgare and other eight medicinalplants against a noncancerous African green monkey kidney(Vero) cell line and an adenocarcinoma cervical cancer(HeLa) cell line [87]

424 Antipyretic Activity F vulgare extract showedantipyretic activity against hyperpyrexia in mice It wasinduced by SC administration of 2mL100 g of a 20aqueous suspension of brewerrsquos yeast As an antipyreticagent ethanolic extract of F vulgare fruit showed a moderateantipyretic activity that was statistically significant after 30and 90min (119875 lt 001) [108]

425 Hypolipidemic Activity The aqueous extract of F vul-gare revealed notable hypolipidemic and antiatherogenicactivity against Triton WR-1339 induced hyperlipidemiain mice Aqueous extract causes significant reduction ofplasma lipid levels that is cholesterol triglycerides LDL-cholesterol and apolipoprotein-B decreased by 40 2361 and 61 respectively and increase in HDL-cholesteroland apolipoprotein A1 by 85 and 58 respectively [88]

426 Hypoglycemic Activity The essential oil of F vulgareexhibits potential hypoglycemic and antioxidant activityagainst streptozotocin induced diabetes in rats Essentialoil (30mgkg body weight) of F vulgare works in the

correction of hyperglycemia from 1625 plusmn 319mgdL to8197 plusmn 197mgdL with 119875 lt 005 and the activity of serumglutathione peroxidase from 5972 plusmn 278Ug Hb to 9960 plusmn638Ug Hb with 119875 lt 005 Also essential oil of fennelimproves the pathological changes noticed in their kidneyand pancreas as compared with the control group of animalThis can prove its effect as antidiabetic in folk Medicine Thismakes the possibility of its inclusion in antidiabetic drugindustry [12]

427 Antispasmodic Activity The antispasmodic activity of25 and 100mLL of alcoholic extract of Foeniculum vulgarealong with other Germanic medicinal plants namelyMelissaofficinalis Rosmarinus officinalisMentha piperitaMatricariachamomilla Carum carvi and Citrus aurantium were testedemploying the guinea pig ileum and using acetylcholine andhistamine as spasmogens An alcoholic extract of the fruits ofFoeniculum vulgare possesses antispasmodic activity whichinhibits the acetylcholine and histamine-induced guineapig ileal contractions in vitro An essential oil which isobtained from the fruits of Foeniculum vulgare 25 120583gmL and10 120583gmL respectively inhibited oxytocin and prostaglandin[72]

428 Apoptotic Activity The apoptotic activities of ethanolextracts from fruits of seven species of Apiaceae familynamely Eryngium planum Archangelica officinalis Pasti-naca sativa Heracleum sibiricum Carum carvi Foenicu-lum vulgare and Levisticum officinale against ML-1mdashhumanacute myeloblastic leukaemia J-4501mdashhuman acute Tcell leukaemia EOLmdashhuman eosinophilic leukaemia HL-60mdashhuman Caucasian promyelocytic leukaemia 1301mdashhuman T cell leukaemia lymphoblast C-8166mdashhuman Tcell leukaemia U-266B1mdashhuman myeloma WICLmdashhumanCaucasian normal B cell and H-9mdashhuman T cell wereinvestigated with the help of Trypan blue assay and AnnexinV fluos assay [86] The ethanol extract from fruit F vulgareshowed the highest mortality in Trypan blue test for J45cell linemdash4 of viable cells and for C8166 cell linemdash100of mortality However the cells of other lines showed thehighest viability HL60mdash60 EOLmdash48 and MLmdash1ndash42The normal cell line H9 and WICL showed 35 and 25of viable cells respectively C8166 cell line and J-45 cell lineshowed the highest level of the apoptotic cells detected byAnnexin V methodmdash100 and 93 respectively Howeverthe cells of two lines HL60 and EOL-1 showed the lowerlevels of apoptotic cellsmdash52 and 60 respectively Highpercentage of apoptotic cells was observed inH9 andWICLmdash76 and 93 respectively [86]

429 Human Liver Cytochrome P450 3A4 Inhibitory ActivityThirteen compounds isolated from the methanolic extract offennel have been found to possess human liver cytochromeP450 3A4 inhibitory activity Among these compounds 5-methoxypsoralen (5-MoP) showed the strongest inhibitionwith an IC50 value of 183120583m and with a mixed type ofinhibition [83]

430 Antiaging Effects Rasul and his coworker developeda base and formulation containing 4 concentrated seedextract of F vulgare This formulation shows notable antiag-ing effect with supporting experimental data related to skinmoisture and transepidermal water loss (TEWL) The basewas insignificant while the formulation showed significanteffects on skin moisture and TEWL The texture parameterenergy showed a significant increase proving that the formu-lation possesses potential antiaging effects [50]

431 Bronchodilatory Effect Ethanol extract and essential oilfrom F vulgare exhibited bronchodilatory activity on con-tracted tracheal chains of guinea pig The potassium channelopening effect of fennel may contribute on its relaxant effecton guinea pig tracheal chains [111] Moreover anethole bearsa striking resemblance to the catecholamines epinephrinenorepinephrine and dopamine This structural similarityappears to be responsible for the various sympathomimeticactivities of F vulgare such as bronchodilatory effect [71]

432 Antioxidant Activities Naturally occurring antioxi-dants can be used to protect human beings from oxidativestress damage [112] Fennel was known as excellent source ofnatural antioxidants and contributed to the daily antioxidantdiet [113]Wild fennel was found to exhibit a free radical scav-enging activity with higher content phenolic and flavonoidthan medicinal and edible fennel and the aerial parts ofthe Italian fennel populations showed the highest DPPHscavenging activity [65] Phenolic compounds of fennelincluding caffeoylquinic acid rosmarinic acid eriodictyol-7-orutinoside quercetin-3-O-galactoside and kaempferol-3-O-glucoside showed antioxidant activities [67] The volatileoil showed strong antioxidant activity in comparison withbutyrated hydroxyanisole and butylated hydroxytolueneEthanol and water extracts of fennel showed less antioxidantactivity compared with essential oil [114]

5 Environmental Application

Foeniculum vulgare that is fennel not only exhibited phar-macological activities but also revealed a few environmentalactivities These activities play a key role in the managementof nematode insect mosquitoes and some harmful larvae ofmalaria producing vector Thus the extracts of F vulgare andisolated biologically active compounds have been evaluatedfor their insecticidal repellent acaricidal larvicidal andnematicidal activity [115ndash119] A brief review on the differenttype of ecofriendly environmental activities as reported onthis plant is summarized below

51 Insecticidal Activities The fruit derived phytoconstitu-ents of F vulgare exhibited prominent insecticidal activi-ties against Sitophilus oryzae Callosobruchus chinensis andLasioderma serricorne This activity was examined usingdirect contact application and fumigation methods Thebiologically active constituents that is phenylpropenes (E)-anethole and estragole and the monoterpene (+)-fenchonewere characterized from Foeniculum fruit By using a filter

26 BioMed Research International

paper diffusion test estragole (0168mg cmminus2) caused 91mortality to S oryzae within 1 day after treatment whereas(+)-fenchone and (E)-anethole gave over 90 mortality at 2and 4 day after treatment respectively

After 2 days of treatment all test compounds (0021mg cmminus2 concentration) revealed potent insecticidal activityagainst C chinensis Whereas after 1 day of treatment (E)-anethole (0105mg cmminus2) gave 100mortality of L serricornewhereas 90 and 60 mortality at 4 day after treatment wasachieved with estragole and (+)-fenchone respectively In afumigation test the compounds were much more effectiveagainst adults of S oryzae C chinensis and L serricorne inclosed cups than in open ones indicating that the insecticidalactivity of test compounds was largely attributable to fumi-gant action As naturally occurring insect-control agents theF vulgare fruit-derived materials described could be usefulfor managing field populations of S oryzae C chinensis andL serricorne [116]

52 Acaricidal Activity Fennel oil shows significant acaricid-al activity againstDermatophagoides farinae andDermatoph-agoides pteronyssinus (+)-fenchone and p-anisaldehyde aremajor constituents of fruit oil of F vulgare P-anisaldehydewas the most toxic compound against D farinae and is muchmore effective compared with benzyl benzoate thymol andestragol [118]

53 Repellent Activity The methanolic extract of fruits ofF vulgare was spectroscopically characterized for the pres-ence of biologically active constituents called (+)-fenchoneand (E)-9-octadecenoic acid The repellent activity of theseconstituents was tested against hungry Aedes aegypti femaleswith the help of skin and patch tests and compared withthat of the commercial repellent agent called NN-diethyl-m-toluamide (DEET) and (Z)-9-octadecenoic acid In askin test with female mosquitoes (+)-fenchone and (Z)-9-octadecenoic acid (04mgcm2) exhibitedmoderate repellentactivity at 30min after treatment whereas DEET providedgt1 h of protection against adult mosquitoes at (02mgcm2)Thus (+)-Fenchone and (E)-9-octadecenoic acid are poten-tial mosquito repellent agents or lead compounds [117]

54 Larvicidal Activity Plant extracts and oils may act asalternatives to conventional pesticides for malaria vectorcontrol By considering this aspect Sedaghat et al [119] inves-tigated the larvicidal activity of essential oils of three plantsof Apiaceae family against malaria vector called Anophe-les stephensi The larvicidal activity was evaluated againstlaboratory-reared larvae by standard method of WHO TheF vulgare oil was the most effective against A stephensiwith LC(50) and LC(90) values of 2010 and 4451 ppmrespectively [119] Additionally the essential oil extracts fromleaves flowers and roots of F vulgare exhibit noticeablelarvicidal activity against fourth-instar larvae of themosquitoCulex pipiens molestus Terpineol and 18-cineole content of Fvulgare are the most effective phytoconstituent against Culexpipiens molestus bites offering complete protection for 16 and2 h respectively [120] Recently Zoubiri et al [57] reported

the larvicidal activity of essential oil of fennel seed againstCulex pipiensmosquitoThus F vulgare can serve as a naturallarvicidal agent

55 Nematicidal Activity Oka et al investigated the in vitronematicidal activity of essential oils extracted from 27 spicesand aromatic plants in pot experiments Twelve of thetwenty-seven essential oils immobilized more than 80 ofjuveniles of the root-knot nematodeMeloidogyne javanica ata concentration of 1000 120583Lliter At this concentration mostof these oils also inhibited nematode hatching Essential oilsof Carum carvi Foeniculum vulgare Mentha rotundifoliaand Mentha spicata showed the highest nematicidal activityamong the in vitro tested oils In 3-liter pot experimentsnematicidal activity of the essential oils and their componentswas confirmed at 200 and 150mgkg respectivelyThe resultssuggest that the essential oils and theirmain componentsmayserve as nematicides [115]

6 Toxicity

The long history of ethnomedicinal application with noreports of any serious side effects suggests that F vulgarecould be considered as safe Inmost toxicity experiments car-ried out on F vulgare no sign of toxicity was observed Shahand his coworker in 1991 investigated the detailed toxicityaccount of ethanolic extract of fennel fruit in experimentalmice with respect to acute and 90 days longer term toxicity[121] In experimentation Shah and his coworker observedthe general symptoms of toxicity and mortality for only 24 hin acute toxicity Whereas in another part of toxicity theystudied the effect of fennel extract on mice with 90 dayslong term treatment Acute toxicity of ethanolic extract of Fvulgarewas assessed in 35mice by using three concentrationsnamely 05 1 and 3 gkg body weight In this investigation Fvulgare exhibited no signs of toxicity and no mortality wasobserved upto the dose level 3 gkg body weight In case oflonger term toxicity ethanolic extract of F vulgare (100mgkgbody weightday) was given in drinking water of animals(30 male and 30 female mice) All external morphologicalhaematological and spermatogenic changes in addition tobody and vital organ weights were recorded The extractcaused no significant chronic mortality as compared tocontrols during this investigation The treated male micegained significant weight during chronic treatment while aloss or no significant change in weight was noticed in thefemale mice treated with the same extract The extracts didnot show spermatotoxic effects Thus Shah and his coworkerconcluded that fennel extract is safe based on both acuteandor long term toxicity studies [121] Additionally the plantextract in doses of 05 1 and 3 gkg (orally) did not causeany deaths These doses do not show any type of toxicityagainst several parameters tested namely locomotor activitybizarre reactions sensitivity to sound social interaction tailposture aggressive behaviour ataxia paralysis convulsionstremors prostration exophthalmos pupil size defecationsalivation urination pattern of respiration nasal dischargecyanosis and piloerection Exceptionally only the 3 gkg dose

BioMed Research International 27

showed signs of reduced locomotor activity and piloerec-tion Otherwise all other parameters were negative [108]In another experiment of acute toxicity different solventextracts namely n-hexane methylene chloride ethyl acetateand methanol extracts of F vulgare upto 55 gkg concentra-tion did not revealed any kind of toxicity in mice LD50being 675 110 692 and 15 gkg for n-hexane methylenechloride ethyl acetate and methanol extracts respectively[68] The plant extract of F vulgare was administered orallyat a dose of 100 200 400 600 800 1000 and 2000mgkgof body weight of mice Each group of animals was undervisual observation for 10 days for the external behavior ofneurological toxicity created by plant extract Even the micereceiving highest dose of F vulgare extract did not show anymortality or toxicity demonstrating the safety profile of theplant extract [89]

The acute oral 50 LD50 for anethole in rats was foundto be 2090mgkg Repeated doses of one-third the LD50 ofanethole (695mgkg) given to rat caused mild liver lesionsIt would therefore appear that in normal therapeutic dosagesanethole would have minimal hepatotoxicity When anetholewas fed to rats daily for one year as 025 of the dietno hepatic damage was seen [122] The acute oral LD50 ofessential oil in rats is 1326mgkg [76] The use of F vulgareessential oil as a remedy for control of primary dysmenorrheaincreases concern about its potential teratogenicity due toits estrogen like activity Evaluation of teratogenicity ofessential oil using limb bud mesenchymal cells showed thatthe essential oil may have toxic effect on fetal cells butthere was no evidence of teratogenicity upto concentrationof 93mgmL of culture medium [123] The overall toxicitystudies carried out on F vulgare accounts for its safety at therecommended therapeutic doses

7 Conclusions

The available scientific research on Foeniculum vulgarehas shown that it is an important medicinal plant used ina wide range of ethnomedical treatments especially forabdominal pains antiemetic aperitif arthritis cancer colicin children conjunctivitis constipation depurative diarrheadieresis emmenagogue fever flatulence gastralgia gastritisinsomnia irritable colon kidney ailments as a laxativeleucorrhoea liver pain mouth ulcer and stomachache Thisplant has been in use for a long period of time withoutany documented serious adverse effects Studies carriedout in the past and present indicate that fennel possessesdiverse health benefits and are an important constituentof food Studies have shown that various extracts offennel possess a range of pharmacological actions such asantiaging antiallergic anticolitic antihirsutism anti-inflam-matory antimicrobial and antiviral antimutagenic antino-ciceptive antipyretic antispasmodic antistress antithromb-otic anxiolytic apoptotic cardiovascular chemomodulatoryaction cytoprotection and antitumor cytotoxicity diureticestrogenic properties expectorant galactogenic gastrointes-tinal effect hepatoprotective human liver cytochrome P4503A4 inhibitory hypoglycemic hypolipidemic memory-en-hancing property nootropic and oculohypotensive activity

supporting its traditional use However the most prominentand the well studied effects are the antimicrobial andantioxidant effects of essential oil of fennel in differentexperimental models The observed health benefits may becredited to the presence of the various phytochemicals likevolatile compounds flavonoids phenolic compounds fattyacids and amino acids

Fennel also contains mineral and trace elements likealuminum barium calcium cadmium cobalt chromiumcopper ironmagnesiummanganese nickel lead strontiumand zinc [124] fat soluble vitamins such as vitamins A Eand K water soluble vitamins like ascorbic acid thiamineriboflavin niacin and pyridoxine essential amino acidslike leucine isoleucine phenylalanine and tryptophane maycontribute to the myriad health beneficial effects at least inpart

Most of the pharmacological studies were conductedusing uncharacterized crude extracts of fennel It is difficultto reproduce the results of these studies and pinpoint thebioactive compounds Hence there is a need for chemi-cal standardization and bioactivity-guided identification ofbioactive compounds Among several classes of chemicalconstituents identified in fennel volatile components of fen-nel essential oil and phenolic compounds are assumed to bethe main bioactive compounds responsible for the majorityof its pharmacological effects However the vast traditionaluse and proven pharmacological activities of fennel indicatethat an immense scope still exists for its chemical explorationFuture studies should be focused on validating the mecha-nism of action responsible for the various beneficial effectsand also on understanding which plant based compounds areresponsible for the reported effectsThe required informationwhen available will enhance our knowledge and appreciationfor the use of fennel in our daily diet Also the outcomeof such chemical studies may further expand its existingtherapeutic potential

Thus there are many areas of research related to thisplant that need to be further explored to fully recognize itsbeneficial effects for society Factors such as geographical andseasonal variation play an important role in the authentica-tion of the chemical constituents responsible for the activitywhich also can be an area of interest Thus it is incumbenton researchers to fill the huge gap of insufficient knowledgeand create awareness among pharmacologists as well as inves-tigators towards providing better medicinal value derivedfrom this plant This can be fulfilled only by generatinginterest among the research community through writing ofcritical appraisals (paper) and extending the interdisciplinaryresearch area to focused studies on Foeniculum vulgare

41 Antimicrobial and Antiviral Activities Foeniculum vul-gare has been used as an ethnic remedy for the cure ofnumerous infectious disorders of bacterial fungal viral andmycobacterial origin Several studies have been carried outin the past validating its antimicrobial antimycobacterialand antiviral potential (summarized in the Table 9) Duskoet al [91] investigated the antibacterial effect of the aqueousextract of 12 medicinal plants of Apiaceae family includingF vulgare An aqueous extract of the aerial part of Fvulgare inhibited the growth of Agrobacterium radiobacterpv tumefaciensErwinia carotovoraPseudomonas fluorescensand Pseudomonas glycinea (Table 9) An aqueous extract ofseed sample inhibited the growth of Enterococcus faecalisStaphylococcus aureus Escherichia coli Klebsiella pneumo-nia Pseudomona aeruginosa Salmonella typhi Salmonellatyphimurium Shigella flexneri and Bacillus cereus with 13ndash22 22ndash24 14ndash24 20-21 21ndash24 11-12 14ndash18 17ndash18 and 24ndash26mm zone of inhibition respectively [3 4] Gulfraz et al[92] investigated the antibacterial effect of the essential oil aswell as ethanolic and methanolic fruit extracts of F vulgareagainst Bacillus cereus Bacillus megaterium Bacillus pumilus

Bacillus subtilis Escherichia coliKlebsiella pneumoniaMicro-coccus luteus Pseudomonas putida Pseudomonas syringaeand Candida albicans According to the results reported byGulfraz et al [92] essential oil of F vulage had significantantimicrobial activities against some of microorganisms ascompared to the methanolic and ethanolic extracts Thediameters of growth inhibition zone ranged from 14 to 31mm(including the diameter of the disc 6mm) with the highestinhibition zone values observed against Bacillus megaterium(31mm) and Bacillus subtilis (29mm) Roby et al [23]investigated antimicrobial effect of the methanol ethanoldiethyl ether and hexane extracts of seed of F vulgare againsttwo species of Gram negative bacteria (Escherichia coli andSalmonella typhi) two species of Gram positive bacteria(Bacillus cereus and Staphylococcus aureus) one species ofyeast (Candida albicans) and one species ofmold (Aspergillusflavus)Themethanolic extract showedmore effective antimi-crobial activity than the other extracts The results fromthe disc diffusion method followed by measurement ofminimum inhibitory concentration (MIC) indicated thatBacillus cereus and Aspergillus flavus were the most sensitivemicroorganisms tested showing the largest inhibition zonesand the lowest MIC values Least activity was exhibitedagainstEscherichia coli with the smallest inhibition zones andthe highest MIC value [23] Shrivastava and Bhargava [93]investigated the antibacterial effect of the crude chloroformand methanol extract of leaves and flowers of F vulgarealong with Raphanus sativus and Brassica nigrum againstEscherichia coli and Staphylococcus aureus Methanol extractof flower of F vulgare showed significant activity againstEscherichia coli whereas crude and chloroform extractsfailed to exhibit antimicrobial activity against Staphylococcusaureus (Table 9) Among different tested bacterial strains the

methanolic fruit extract of F vulgare inhibited the growthof Staphylococcus aureus and Bacillus pumilus with 1127 and1267mm zone of inhibition respectively [7]

Several studies indicating the antifungal effect of Fvulgare along with antibacterial effect are also reported inthe literature Martins et al [94] investigated the antibacterialand antifungal effects of three essential oils of Portugueseplants namely Foeniculum vulgareMentha spicata and Ros-marinus officinalis against Staphylococcus aureus Escherichiacoli Klebsiella pneumonia Pseudomona aeruginosa Staphy-lococcus epidermidis Candida albicans and phytopathogenic

diseases [97] In an in vitro study aqueous and alcoholicseed extracts of F vulgare exhibited inhibitory effect againstAlternaria alternata Mucor rouxii and Aspergillus flavus[98] Interestingly aqueous seed extract of F vulgare showedstrongest antifungal activity as compared to reference fungi-cidal agent that is griseofulvin [99]

All of the above mentioned studies were carried outon the crude extracts and it is difficult to pinpoint theactive antimicrobial metabolite A phenylpropanoid deriva-tive called dillapional characterized from F vulgare stem wasfound to be an antimicrobial constituent with MIC values of125 250 and 125 against Bacillus subtilis Aspergillus nigerand Cladosporium cladosporioides respectively A coumarinderivative scopoletin was also isolated as a marginallyantimicrobial agent [100] The characterization of sevendifferent types of oxygenatedmonoterpenes frommethylene

chloride crude extract of F vulgare [101] suggested thatthe crude extract containing monoterpenes could be a newmedicinal resource for antibacterial agents

A total of 78 compounds were identified from theactive antimycobacterial fraction of F vulgare with thehelp of gas chromatography-mass spectra (GC-MS) Outof these twenty compounds were tested against one sensi-tive and three MDR strains of Mycobacterium tuberculosisusing the Alamar Blue microassay Compounds that showedsome degree of antimycobacterial activity against all strainstested were the following linoleic acid (MIC 100 120583gmL)oleic acid (MIC 100 120583gmL) 13-benzenediol (MIC 100ndash200120583gmL) undecanal (MIC 50ndash200120583gmL) and 24-undecadienal (MIC 25ndash50120583gmL) 24-Undecadienal wasthe most active compound against multidrug resistant Mtuberculosis speciesThus the dietary intake of F vulgaremaylower the risk ofM tuberculosis infection [63]

Orhan et al [5] studied the antiviral activity of theessential oil of fruit sample of F vulgare along with 12other Turkish medicinal plants against the DNA virusHerpessimplex type-1 (HSV-1) and the RNA virus parainfluenzatype-3 (PI-3) Most of the oils and compounds displayedstrong antiviral effects against HSV-1 ranging between 08and 0025 120583gmL However the samples tested were lesseffective against PI-3 with results ranging between 16 and02 120583gmL Only the essential oils of Anethum graveolensFoeniculum vulgare (fully mature) Mentha piperita Menthaspicata Ocimum minutiflorum Ocimum vulgaris and Sat-ureja cuneifolia inhibited this virus significantly

All these literature findings validated the traditional usesof Foeniculum vulgare in infectious disorders like abdomi-nal pains antiemetic arthritis conjunctivitis constipationdepurative diarrhea dieresis fever flatulence gastralgia gas-tritis insomnia irritable colon mouth ulcer stomachacherespiratory disorders skin diseases and so forth There isalways a need for new antimicrobial agents due to rapiddevelopment of resistance Bioactive metabolites of F vulgaremay be a potential source for new antimicrobial agents

42 Anti-Inflammatory Activity Oral administration ofmethanol extract of F vulgare fruit to rat and mice exhibitedinhibitory effects against acute and subacute inflammatorydiseases The anti-inflammatory activity of methanol extractwas evaluated by using three screening protocols namelycarrageenan-induced paw edema arachidonic acid-inducedear edema and formaldehyde-induced arthritis Theseare widely used for testing nonsteroidal anti-inflammatorydrugs For acute inflammationmethanol extract (200mgkg)exhibits significant inhibition of paw edema (69) inducedby carrageenan injection as compared to the control groupof animals Methanol extract of F vulgare also inhibitsear-edema (70) induced by arachidonic acid in mice Thelevel of serum transaminase aspartate aminotransferase(AST) and alanine aminotransferase (ALT) significantlyincreases in the presence of methanolic extract of F vulgareon inflammation induced by formaldehyde as comparedto control group The assessment of the level of AST and

ALT provides a good and simple tool to measure the anti-inflammatory activity of the target compounds [102] Theseoverall results seem to suggest that F vulgare FME mayact on both the cyclooxygenase and lipoxygenase pathways[79]

43 Antiallergic Activity Methanolic extract of F vulgarefruit showed significant inhibitory effect on DNFB- (24-dinitrofluorobenzene-) induced delayed type hypersensitiv-ity after oral administration of 200mgkg once a day for7 days The inhibitory effect on immunologically inducedswelling suggests the possible immunosuppressive propertiesof F vulgare [79]

44 Hepatoprotective Activity Essential oil of F vulgareseeds revealed a potent hepatoprotective effect against acutehepatotoxicity produced by carbon tetrachloride in ratsOral administration of F vulgare essential oil decreases thelevels of serum aspartate aminotransferase (AST) alanineaminotransferase (ALT) alkaline phosphatase (ALP) andbilirubin as compared to the control group Ozbek et alsuggest that the constituents (d-limonene and 120573-myrcene) ofessential oil may have played a key role in the protection ofliver from CCl

4toxicity [9]

45 Anxiolytic Activity Anxiety is the unpleasant feeling offear and concern When anxiety becomes excessive it maybe considered as an anxiety disorder Anxiolytic fennel isa drug used for the treatment of anxiety and its relatedpsychological and physical symptoms Naga Kishore et al[89] investigated the anxiolytic activity of ethanolic extract ofF vulgare fruit with the help of elevated plus maze rota rodopen field test and whole board models The 100 to 200mgdose of extract per kg of body weight of animal revealedsignificant activity when compared to reference anxiolyticdrug called diazepam (1mgkg) Thus fennel extract maypossess anxiolytic activity supporting its traditional claimabout anxiolytic activity reported in 19th edition of Pharma-cology and Pharmacotherapeutics by Sathodkar Bhandarkarand Rege

46 Antistress Activity Drug and food of natural originplay a significant role in public healthcare systems and arebeing investigated as remedies for a number of stress-relateddisorders [103]Thewhole plant extract of F vulgare exhibitednotable antistress effect against stress induced by forcefulswimming of test animals The key parameters that isurinary levels of vanillyl mandelic acid (VMA) and ascorbicacid in rats were used to evaluate antistress activity Theplant extract (50 100 and 200mgkg body weight) showeda significant improvement in urinary levels of VMA (119875 lt0001) and ascorbic acid excretion levels (119875 lt 0001) in testanimals when compared to the normal basal levels in controlgroup of animalsThus the extract of entire plant of F vulgareacts as an antistress agent [13]

47 Memory-Enhancing Property There are a number ofplants whose consumption is believed to enhance memory

22 BioMed Research International

and intelligence These were usually given to children as partof their food F vulgaris an ayurvedic rasayana (mixture)possessing multiple neuropharmacological activities Theantidepressant activity of fennel has been well documentedin ethnomedicine The whole plants extract (50 100 and200mgkg) of F vulgare exhibited memory-enhancing effectagainst scopolamine-induced amnesic rats This experimentwas evaluated by conditioned avoidance response (CAR)technique The CAR of rats administered with the extractincreased gradually to 95 over 7 to 12 days The acquisition(time to achieve 95 CAR) for rats administered with theextract was dose- and time-dependent compared to controlgroup which took 12 days for acquisition The percentavoidance was always higher in the extract-treated groupsas compared to control group Animals receiving 200mgkgbody weight of the extract took ten days while groups treatedwith 100 and 50mgkg doses of the extract required elevenand twelve days respectively to reach the point of acquisitionAdministration of scopolamine produced amnesia as seenfrom reduction in the observed CAR Amnesia was greaterin the control group than in extract-treated groups How-ever continued treatment with F vulgare produced betterretention and recovery in a dose-dependent manner thanthe vehicle-treated animals Recovery from scopolamine-induced amnesia in the extract-treated groups took 3ndash5 dayswhen compared to normal (control) group which took over6 days This overall progress suggests that F vulgare extractpossesses memory-enhancing property [13]

48 Nootropic Activity Alzheimerrsquos disease is a neurode-generative disorder associated with a decline in cognitiveabilities Dementia is one of the age-related mental problemsand a characteristic symptom of Alzheimerrsquos disease Thereis some evidence in favor of use of F vulgare for the treat-ment of cognitive disorders like dementia and Alzheimerrsquosdisease Methanol extract of the whole plant of F vul-gare administered for eight successive days ameliorated theamnesic effect of scopolamine and aging-induced memorydeficits inmiceThis extract increased step-down latency andacetylcholinesterase inhibition in mice significantly Thus Fvulgaremay be employed in treatment of cognitive disorderssuch as dementia and Alzheimerrsquos disease as a nootropic andanticholinesterase agent [80]

49 Antihirsutism Activity Idiopathic hirsutism is definedas the occurrence of excessive male pattern hair growth inwomen who have a normal ovulatory menstrual cycle andnormal levels of serum androgens It may be a disorder ofperipheral androgen metabolism Traditionally Foeniculumvulgare has been used as an estrogenic agent It has beenreputed to increase milk secretion promote menstruationfacilitate birth and increase libido On considering aboveaspect Javidnia and his research team evaluated the antihir-sutism activity of ethanolic extract of F vulgare seed againstidiopathic hirsutism by preparing cream containing 1 and 2of fennel extract The efficacy of treatment with the creamcontaining 2 fennel is better than the cream containing 1fennel and these two were more potent than placebo (control

group) The mean values of hair diameter reduction were78 183 and minus05 for patients receiving the creamscontaining 1 2 and 0 (placebo) respectively [78]

410 Estrogenic Properties Since the discovery of the estrusinducing effects of some plant products in 1926 consider-able effort has been devoted towards the characterizationof phytoestrogens including flavonoids isoflavonoids chal-cones coumestans stilbenes lignans saponins and essentialoils [16] F vulgare has estrogen-like activity In male ratstotal concentration of protein was found to be significantlydecreased in testes and in vasa deferentia whereas increasedin seminal vesicles and in prostate gland On the otherhand simultaneous decrease in the activities of acid andalkaline phosphatase in all these regions (except that alka-line phosphatase was unchanged in vasa) due to the oraladministration of acetone extract of F vulgare fruit wasobserved In female rats oral administration of the extract for10 days led to vaginal cornification and oestrus cycle [8] Totalconcentration of nucleic acids and protein as well as the organweights increased in both the tissues namely mammaryglands and oviducts due to the oral administration of acetoneextract (50 150 and 250120583g100 g body wt) of F vulgare seeds[104] Fennel oil was reported to exhibit estrogenic activitypromote menstruation and alleviate the symptoms of femaleclimacteric and increase libido [71] Administration of fenneloil (25 and 50 120583gmL final concentration in the organ bath)failed to exhibit any remarkable effect in uterine contrac-tion While 10 20 and 40 120583gml concentration of fennel oilrevealed significant inhibitory effect against prostaglandinE2 Fennel oil significantly reduces the frequency of uterinecontraction induced by prostaglandin E2 Thus the extractsof F vulgare have strong estrogenic activity [76]

411 Galactogenic Activity Foeniculum vulgare has been usedformillennia to increasemilk secretion [105]Thus F vulgarebelongs to galactagogue substance Structural similarity ofits main constituent anethole to dopamine seems to beresponsible for galactogenic activityDopamine acts to inhibitthe secretion of the milk-producing hormone prolactinAnethole might influence milk secretion by competing withdopamine at the appropriate receptor sites thereby inhibitingthe antisecretory action of dopamine on prolactin [71] It wasreported that anol (demethylated anethole) causes growthof the lobule-alveolar system in the mammary glands ofimmature female rabbits and induces menstruation in miceand other experimental animals Anol also gave positiveresults in the Jadassohn nipple test a test which involvesthe measurement of changes induced in the nipples ofguinea pigs subjected to the cutaneous application of sexhormones However further research suggests that the actualpharmacologically active agents responsible for galactogenicactivity are polymers of anethole such as dianethole andphotoanethole rather than anol or anethole itself [20 76]

412 Expectorant Activity F vulgare seeds stimulate theciliary motility of the respiratory apparatus and enhance the

BioMed Research International 23

external transport of extraneous corpuscles This action sug-gests a use for fennel in treating bronchial and bronchopul-monary afflictions and in particularly polluted environments[106] The volatile oil of F vulgare stimulates the contractionof the smooth muscles of the trachea an action that couldfacilitate the expectoration of mucus bacteria and othercorpuscles extraneous to the respiratory tracts [74]

413 Anticolitic Activity Essential oil of fennel regulates themotility of smooth muscles of the intestine while at thesame time reducing intestinal gas Alone or combined withother plant medicinals Foeniculum vulgare is indicated in thetreatment of spastic gastrointestinal disturbances in someforms of chronic colitis (which resist other treatments) indyspepsias from gastrointestinal atony in dyspepsias withthe sensation of heaviness in the stomach and so forthTheaddition of fennel to preparations containing anthraquinoniccomponents reduces the occurrence of abdominal pain oftenassociated with this type of laxative [73]

414 Antinociceptive Activity Antinociceptive means anysubstance that inhibits nociception which is a physiologicalprocess underlying the sensation of pain Briefly it reducesthe sensitivity to painful stimuli The various extracts ofaerial part of F vulgare namely hexane methylene chlorideethyl acetate and methanolic extract showed remarkableantinociceptive activity against acetic acid induced writhingin mice [68] The methanolic extract of the aerial parts ofF vulgare exhibited the highest antinociceptive activity at adose level of 2000mgkg while the activity exhibited by theethyl acetate extract was at dose level 800mgkgOn the otherhand n-hexane extract (700mgkg) and methylene chlorideextract (500mgkg) exhibited similar antinociceptive activi-ties being less than peripheral antinociceptive reference drug(acetyl salicylic acid) [68]

415 Diuretic Activity A diuretic is any substance thatpromotes the production of urine Briefly it is an agentthat promotes diuresis Diuretics work by promoting theexpulsion of urine (measured as the urine volume [UV]excreted) and urinary sodium (UNa) from the body and thishelps reduce the volume of blood circulating through thecardiovascular system Caceres et al [107] performed a studyin conscious animals and administered a powdered extractof the whole plant (F vulgare) which had no effect on UVor UNa The ethanolic extract of F vulgare fruit revealedexcellent diuretic activity and proves the earlier folk claimof F vulgare which was reported in the United State ofAmerica (Table 5) The fruit extract showed statistically ahighly significant diuretic effect F vulgare induced diuresis(500mgkg dose)was comparable to that of reference diureticagent urea (960mgkg dose) in mice with a urine outputthat was almost double that of the control group Thediuresis was not associated with changes in sodium andorpotassium excretion [108] In another part of the study theauthors showed that Foeniculum vulgare had little effect onthe noradrenalin contractile responses of aortic rings thus

suggesting that it worked mainly as a diuretic and natriureticwith little effect on arterial vascular tone [77]

416 Cardiovascular Activity An aqueous extract of F vul-gare leaves possesses potential cardiovascular action Thiseffect was investigated using pentobarbital-anaesthetisedmale albino Sprague-Dawley rats [75] An intravenousadministration of the lyophilized boiled water extract ofleaves produced a significant dose-related reduction in arte-rial blood pressure without affecting the heart rate or respi-ratory rate On the other hand the nonboiled aqueous extractshowed very little hypotensive activityThe hypotensive effectof the boiling water extract appeared not to be mediated viaadrenergicmuscarinic ganglionic or serotonergic receptorshowever histamine antagonists inhibited the hypotensiveeffect in a dose-related manner [75]

417 Oculohypotensive Activity The aqueous seed extract ofF vulgare demonstrated significant oculohypotensive activityusing water loading and steroid induced glaucoma modelThis extract exhibited 1749 2116 and 2203 reduction ofintraocular pressure in normotensive rabbits at 03 06and 12 (wv) concentrations respectively A maximummean difference of 3120 was observed between vehiclestreated and extracts treated eyes in water loading experi-mental animal model while a maximum mean intraocularpressure lowering of 3129 was observed in steroid inducedmodel of glaucoma Thus the aqueous extract of F vulgarerevealed oculohypotensive activity which was found to be asgood as that of reference standard antiglaucoma drugs calledtimolol [84]

418 Antithrombotic Activity Tognolini et al [55] providedevidence of potent inhibitory activity of essential oil of F vul-gare against platelet aggregation induced byADP arachidonicacid and collagen in guinea pig plasma Similar findingswere reported by Yoshioka and Tamada [109] for aggregationof rabbit platelets by an aromatic factor of fennel oil Theessential oil and anethole (a constituent of oil) of F vulgaretested in vitro in rat aorta with or without endotheliumdisplayed comparable NO-independent vasorelaxant activityat antiplatelet concentrations It supports the safety of Fvulgare that is free from cytotoxic effects Anethole and Fvulgare did not cause cytotoxicity when incubated for 30minupto 300 120583gmL in platelet viability test This concentrationwas largely compatible with those adopted in the functionalin vitro tests In vivo both F vulgare essential oil andanethole orally administered in a subacute treatment to mice(30mgkgday for 5 days) showed significant antithrom-botic activity preventing the paralysis induced by collagen-epinephrine intravenous injection (70 and 83 protectionresp)Thus essential oil and its main component anethole ofF vulgare showed a safe antithrombotic activity in guinea pigplasma that seems due to their broad spectrum antiplateletactivity clot destabilizing effect and vasorelaxant action [55]

419 Antimutagenic Effect Essential oil of F vulgare revealednoteworthy protective effects against genotoxicity in mice

24 BioMed Research International

induced by cyclophosphamide Genotoxicity and cytotoxicitywere assessed by using mice bone marrow chromosomalaberration micronucleus and sperm abnormality assaysrespectively Oral administration of essential oil (1 and2mLkg) significantly inhibited the frequencies of aberrantmetaphases chromosomal aberrations micronuclei forma-tion and cytotoxicity in mouse bone marrow cells inducedby cyclophosphamide and also produced a significant reduc-tion of abnormal sperm and antagonized the reduction ofcyclophosphamide induced superoxide dismutase catalaseand glutathione activities and inhibited increased malondi-aldehyde content in the liver Additionally F vulgare inhibitsthe oxidative stress induced by cyclophosphamide [90]

420 Gastrointestinal Effect Theaqueous extract of F vulgareshowed remarkable antiulcerogenic effect against ethanol-induced gastric lesions in rats It was found that pretreatmentwith aqueous extract significantly reduced ethanol-inducedgastric damageThis effect of aqueous extract was highest andstatistically significant in 300mgkg group comparedwith thecontrol (119875 lt 0001) group of animal Additionally aqueousextract of F vulgare significantly reduced the whole bloodmalondialdehyde levels while significantly increased nitritenitrate ascorbic acid retinol and beta-carotene levels Thusaqueous extract of F vulgare fruit had clearly a protectiveeffect against ethanol-induced gastric mucosal lesion in rats[81]

421 Chemomodulatory Action The chemopreventive effectof different doses of test diet of Foeniculum vulgare seeds wasexamined against 712-dimethylbenz(a)anthracene- (DMBA-) induced skin papillomagenesis and benzo(a)pyrene-[B(a)P-] induced forestomach papillomagenesis at the peri-initiational level in Swiss albino mice Fennel seeds exhibita significant reduction in the skin and the fore-stomachtumor incidence and tumor multiplicity as compared tothe control group Further biochemical assays showeda significant increase in the contentactivities of phase Ienzymes especially in the case of 6 test diet A concomitantincrease in the activities of the phase II enzymes wasobserved with all the doses of test diet under study Asignificant enhancement in the activities of antioxidantenzymes was observed especially at 4 and 6 test diets offennel These findings were indicative of chemopreventivepotential of fennel against carcinogenesis This is the firstreport showing chemopreventive potential of seeds of fennelagainst carcinogenesis [85]

422 Cytoprotection and Antitumor Activity Anethole is theprincipal active component of fennel seeds which has exhib-ited anticancer activity Al-Harbi et al studied the antitumoractivity of anethole against Ehrlich ascites carcinoma inducedin a tumor model in Swiss albino mice The study revealedthat anethole increased survival time reduced tumor weightand reduced the volume and body weight of the Ehrlichascites tumour-bearing mice It also produced a significantcytotoxic effect in the Ehrlich ascites tumour cells in the pawreduced the levels of nucleic acids and malondialdehyde and

increased glutathione concentrations [110] In vitro cytopro-tection activity of methanolic extract of Foeniculum vulgarewas evaluated against normal human blood lymphocytes bymicronucleus assay and antitumor activity against B16F10melanoma cell line by Trypan blue exclusion assay for cellviability Lymphocyte culture treated with 70 methanolicextract of Foeniculum vulgare showed very less percentage ofmicronucleus that is 0006 as compared to standard drugdoxorubicin which showed 0018 micronucleus On theother hand 70methanolic extract of Foeniculum vulgare haspotent antitumor activity at the concentration of 200120583gmLThe results suggest that the Foeniculum vulgare could beconsidered as a natural resource of antitumor agents as wellas cytoprotective to normal cells [11]

423 Cytotoxicity Kaileh and his coworker investigated thecytotoxic effect of organic extracts of 24 selected Palestinianmedicinal plant species The plant selection was based onexisting ethnobotanic information and interviews with localhealers The extracts of the plants under investigation weretested for their potential antitumor (cytotoxic) effect on themurine fibrosarcoma L929sA cells and on the human breastcancer cells MDA-MB231 and MCF7 The extract from Fvulgare presented an IC (50) value at 24 h of 700 plusmn 28 and500plusmn17 120583gmL on L929sA andMCF7 cells respectivelyThenuclear transcription factor NFkappaB or NF120581B regulatesthe expression of various genes They further investigatedthe effect of nine promising plant extracts withheld fromthe first cell viability screening on NF120581B activation Thedichloromethane and methanol (1 1) extract of aerial part ofF vulgare revealed immunomodulatory NF120581B activities [82]Also Berrington and Lall investigated the in vitro cytotoxicityof acetone extracts of F vulgare and other eight medicinalplants against a noncancerous African green monkey kidney(Vero) cell line and an adenocarcinoma cervical cancer(HeLa) cell line [87]

424 Antipyretic Activity F vulgare extract showedantipyretic activity against hyperpyrexia in mice It wasinduced by SC administration of 2mL100 g of a 20aqueous suspension of brewerrsquos yeast As an antipyreticagent ethanolic extract of F vulgare fruit showed a moderateantipyretic activity that was statistically significant after 30and 90min (119875 lt 001) [108]

425 Hypolipidemic Activity The aqueous extract of F vul-gare revealed notable hypolipidemic and antiatherogenicactivity against Triton WR-1339 induced hyperlipidemiain mice Aqueous extract causes significant reduction ofplasma lipid levels that is cholesterol triglycerides LDL-cholesterol and apolipoprotein-B decreased by 40 2361 and 61 respectively and increase in HDL-cholesteroland apolipoprotein A1 by 85 and 58 respectively [88]

426 Hypoglycemic Activity The essential oil of F vulgareexhibits potential hypoglycemic and antioxidant activityagainst streptozotocin induced diabetes in rats Essentialoil (30mgkg body weight) of F vulgare works in the

correction of hyperglycemia from 1625 plusmn 319mgdL to8197 plusmn 197mgdL with 119875 lt 005 and the activity of serumglutathione peroxidase from 5972 plusmn 278Ug Hb to 9960 plusmn638Ug Hb with 119875 lt 005 Also essential oil of fennelimproves the pathological changes noticed in their kidneyand pancreas as compared with the control group of animalThis can prove its effect as antidiabetic in folk Medicine Thismakes the possibility of its inclusion in antidiabetic drugindustry [12]

427 Antispasmodic Activity The antispasmodic activity of25 and 100mLL of alcoholic extract of Foeniculum vulgarealong with other Germanic medicinal plants namelyMelissaofficinalis Rosmarinus officinalisMentha piperitaMatricariachamomilla Carum carvi and Citrus aurantium were testedemploying the guinea pig ileum and using acetylcholine andhistamine as spasmogens An alcoholic extract of the fruits ofFoeniculum vulgare possesses antispasmodic activity whichinhibits the acetylcholine and histamine-induced guineapig ileal contractions in vitro An essential oil which isobtained from the fruits of Foeniculum vulgare 25 120583gmL and10 120583gmL respectively inhibited oxytocin and prostaglandin[72]

428 Apoptotic Activity The apoptotic activities of ethanolextracts from fruits of seven species of Apiaceae familynamely Eryngium planum Archangelica officinalis Pasti-naca sativa Heracleum sibiricum Carum carvi Foenicu-lum vulgare and Levisticum officinale against ML-1mdashhumanacute myeloblastic leukaemia J-4501mdashhuman acute Tcell leukaemia EOLmdashhuman eosinophilic leukaemia HL-60mdashhuman Caucasian promyelocytic leukaemia 1301mdashhuman T cell leukaemia lymphoblast C-8166mdashhuman Tcell leukaemia U-266B1mdashhuman myeloma WICLmdashhumanCaucasian normal B cell and H-9mdashhuman T cell wereinvestigated with the help of Trypan blue assay and AnnexinV fluos assay [86] The ethanol extract from fruit F vulgareshowed the highest mortality in Trypan blue test for J45cell linemdash4 of viable cells and for C8166 cell linemdash100of mortality However the cells of other lines showed thehighest viability HL60mdash60 EOLmdash48 and MLmdash1ndash42The normal cell line H9 and WICL showed 35 and 25of viable cells respectively C8166 cell line and J-45 cell lineshowed the highest level of the apoptotic cells detected byAnnexin V methodmdash100 and 93 respectively Howeverthe cells of two lines HL60 and EOL-1 showed the lowerlevels of apoptotic cellsmdash52 and 60 respectively Highpercentage of apoptotic cells was observed inH9 andWICLmdash76 and 93 respectively [86]

429 Human Liver Cytochrome P450 3A4 Inhibitory ActivityThirteen compounds isolated from the methanolic extract offennel have been found to possess human liver cytochromeP450 3A4 inhibitory activity Among these compounds 5-methoxypsoralen (5-MoP) showed the strongest inhibitionwith an IC50 value of 183120583m and with a mixed type ofinhibition [83]

430 Antiaging Effects Rasul and his coworker developeda base and formulation containing 4 concentrated seedextract of F vulgare This formulation shows notable antiag-ing effect with supporting experimental data related to skinmoisture and transepidermal water loss (TEWL) The basewas insignificant while the formulation showed significanteffects on skin moisture and TEWL The texture parameterenergy showed a significant increase proving that the formu-lation possesses potential antiaging effects [50]

431 Bronchodilatory Effect Ethanol extract and essential oilfrom F vulgare exhibited bronchodilatory activity on con-tracted tracheal chains of guinea pig The potassium channelopening effect of fennel may contribute on its relaxant effecton guinea pig tracheal chains [111] Moreover anethole bearsa striking resemblance to the catecholamines epinephrinenorepinephrine and dopamine This structural similarityappears to be responsible for the various sympathomimeticactivities of F vulgare such as bronchodilatory effect [71]

432 Antioxidant Activities Naturally occurring antioxi-dants can be used to protect human beings from oxidativestress damage [112] Fennel was known as excellent source ofnatural antioxidants and contributed to the daily antioxidantdiet [113]Wild fennel was found to exhibit a free radical scav-enging activity with higher content phenolic and flavonoidthan medicinal and edible fennel and the aerial parts ofthe Italian fennel populations showed the highest DPPHscavenging activity [65] Phenolic compounds of fennelincluding caffeoylquinic acid rosmarinic acid eriodictyol-7-orutinoside quercetin-3-O-galactoside and kaempferol-3-O-glucoside showed antioxidant activities [67] The volatileoil showed strong antioxidant activity in comparison withbutyrated hydroxyanisole and butylated hydroxytolueneEthanol and water extracts of fennel showed less antioxidantactivity compared with essential oil [114]

5 Environmental Application

Foeniculum vulgare that is fennel not only exhibited phar-macological activities but also revealed a few environmentalactivities These activities play a key role in the managementof nematode insect mosquitoes and some harmful larvae ofmalaria producing vector Thus the extracts of F vulgare andisolated biologically active compounds have been evaluatedfor their insecticidal repellent acaricidal larvicidal andnematicidal activity [115ndash119] A brief review on the differenttype of ecofriendly environmental activities as reported onthis plant is summarized below

51 Insecticidal Activities The fruit derived phytoconstitu-ents of F vulgare exhibited prominent insecticidal activi-ties against Sitophilus oryzae Callosobruchus chinensis andLasioderma serricorne This activity was examined usingdirect contact application and fumigation methods Thebiologically active constituents that is phenylpropenes (E)-anethole and estragole and the monoterpene (+)-fenchonewere characterized from Foeniculum fruit By using a filter

26 BioMed Research International

paper diffusion test estragole (0168mg cmminus2) caused 91mortality to S oryzae within 1 day after treatment whereas(+)-fenchone and (E)-anethole gave over 90 mortality at 2and 4 day after treatment respectively

After 2 days of treatment all test compounds (0021mg cmminus2 concentration) revealed potent insecticidal activityagainst C chinensis Whereas after 1 day of treatment (E)-anethole (0105mg cmminus2) gave 100mortality of L serricornewhereas 90 and 60 mortality at 4 day after treatment wasachieved with estragole and (+)-fenchone respectively In afumigation test the compounds were much more effectiveagainst adults of S oryzae C chinensis and L serricorne inclosed cups than in open ones indicating that the insecticidalactivity of test compounds was largely attributable to fumi-gant action As naturally occurring insect-control agents theF vulgare fruit-derived materials described could be usefulfor managing field populations of S oryzae C chinensis andL serricorne [116]

52 Acaricidal Activity Fennel oil shows significant acaricid-al activity againstDermatophagoides farinae andDermatoph-agoides pteronyssinus (+)-fenchone and p-anisaldehyde aremajor constituents of fruit oil of F vulgare P-anisaldehydewas the most toxic compound against D farinae and is muchmore effective compared with benzyl benzoate thymol andestragol [118]

53 Repellent Activity The methanolic extract of fruits ofF vulgare was spectroscopically characterized for the pres-ence of biologically active constituents called (+)-fenchoneand (E)-9-octadecenoic acid The repellent activity of theseconstituents was tested against hungry Aedes aegypti femaleswith the help of skin and patch tests and compared withthat of the commercial repellent agent called NN-diethyl-m-toluamide (DEET) and (Z)-9-octadecenoic acid In askin test with female mosquitoes (+)-fenchone and (Z)-9-octadecenoic acid (04mgcm2) exhibitedmoderate repellentactivity at 30min after treatment whereas DEET providedgt1 h of protection against adult mosquitoes at (02mgcm2)Thus (+)-Fenchone and (E)-9-octadecenoic acid are poten-tial mosquito repellent agents or lead compounds [117]

54 Larvicidal Activity Plant extracts and oils may act asalternatives to conventional pesticides for malaria vectorcontrol By considering this aspect Sedaghat et al [119] inves-tigated the larvicidal activity of essential oils of three plantsof Apiaceae family against malaria vector called Anophe-les stephensi The larvicidal activity was evaluated againstlaboratory-reared larvae by standard method of WHO TheF vulgare oil was the most effective against A stephensiwith LC(50) and LC(90) values of 2010 and 4451 ppmrespectively [119] Additionally the essential oil extracts fromleaves flowers and roots of F vulgare exhibit noticeablelarvicidal activity against fourth-instar larvae of themosquitoCulex pipiens molestus Terpineol and 18-cineole content of Fvulgare are the most effective phytoconstituent against Culexpipiens molestus bites offering complete protection for 16 and2 h respectively [120] Recently Zoubiri et al [57] reported

the larvicidal activity of essential oil of fennel seed againstCulex pipiensmosquitoThus F vulgare can serve as a naturallarvicidal agent

55 Nematicidal Activity Oka et al investigated the in vitronematicidal activity of essential oils extracted from 27 spicesand aromatic plants in pot experiments Twelve of thetwenty-seven essential oils immobilized more than 80 ofjuveniles of the root-knot nematodeMeloidogyne javanica ata concentration of 1000 120583Lliter At this concentration mostof these oils also inhibited nematode hatching Essential oilsof Carum carvi Foeniculum vulgare Mentha rotundifoliaand Mentha spicata showed the highest nematicidal activityamong the in vitro tested oils In 3-liter pot experimentsnematicidal activity of the essential oils and their componentswas confirmed at 200 and 150mgkg respectivelyThe resultssuggest that the essential oils and theirmain componentsmayserve as nematicides [115]

6 Toxicity

The long history of ethnomedicinal application with noreports of any serious side effects suggests that F vulgarecould be considered as safe Inmost toxicity experiments car-ried out on F vulgare no sign of toxicity was observed Shahand his coworker in 1991 investigated the detailed toxicityaccount of ethanolic extract of fennel fruit in experimentalmice with respect to acute and 90 days longer term toxicity[121] In experimentation Shah and his coworker observedthe general symptoms of toxicity and mortality for only 24 hin acute toxicity Whereas in another part of toxicity theystudied the effect of fennel extract on mice with 90 dayslong term treatment Acute toxicity of ethanolic extract of Fvulgarewas assessed in 35mice by using three concentrationsnamely 05 1 and 3 gkg body weight In this investigation Fvulgare exhibited no signs of toxicity and no mortality wasobserved upto the dose level 3 gkg body weight In case oflonger term toxicity ethanolic extract of F vulgare (100mgkgbody weightday) was given in drinking water of animals(30 male and 30 female mice) All external morphologicalhaematological and spermatogenic changes in addition tobody and vital organ weights were recorded The extractcaused no significant chronic mortality as compared tocontrols during this investigation The treated male micegained significant weight during chronic treatment while aloss or no significant change in weight was noticed in thefemale mice treated with the same extract The extracts didnot show spermatotoxic effects Thus Shah and his coworkerconcluded that fennel extract is safe based on both acuteandor long term toxicity studies [121] Additionally the plantextract in doses of 05 1 and 3 gkg (orally) did not causeany deaths These doses do not show any type of toxicityagainst several parameters tested namely locomotor activitybizarre reactions sensitivity to sound social interaction tailposture aggressive behaviour ataxia paralysis convulsionstremors prostration exophthalmos pupil size defecationsalivation urination pattern of respiration nasal dischargecyanosis and piloerection Exceptionally only the 3 gkg dose

BioMed Research International 27

showed signs of reduced locomotor activity and piloerec-tion Otherwise all other parameters were negative [108]In another experiment of acute toxicity different solventextracts namely n-hexane methylene chloride ethyl acetateand methanol extracts of F vulgare upto 55 gkg concentra-tion did not revealed any kind of toxicity in mice LD50being 675 110 692 and 15 gkg for n-hexane methylenechloride ethyl acetate and methanol extracts respectively[68] The plant extract of F vulgare was administered orallyat a dose of 100 200 400 600 800 1000 and 2000mgkgof body weight of mice Each group of animals was undervisual observation for 10 days for the external behavior ofneurological toxicity created by plant extract Even the micereceiving highest dose of F vulgare extract did not show anymortality or toxicity demonstrating the safety profile of theplant extract [89]

The acute oral 50 LD50 for anethole in rats was foundto be 2090mgkg Repeated doses of one-third the LD50 ofanethole (695mgkg) given to rat caused mild liver lesionsIt would therefore appear that in normal therapeutic dosagesanethole would have minimal hepatotoxicity When anetholewas fed to rats daily for one year as 025 of the dietno hepatic damage was seen [122] The acute oral LD50 ofessential oil in rats is 1326mgkg [76] The use of F vulgareessential oil as a remedy for control of primary dysmenorrheaincreases concern about its potential teratogenicity due toits estrogen like activity Evaluation of teratogenicity ofessential oil using limb bud mesenchymal cells showed thatthe essential oil may have toxic effect on fetal cells butthere was no evidence of teratogenicity upto concentrationof 93mgmL of culture medium [123] The overall toxicitystudies carried out on F vulgare accounts for its safety at therecommended therapeutic doses

7 Conclusions

The available scientific research on Foeniculum vulgarehas shown that it is an important medicinal plant used ina wide range of ethnomedical treatments especially forabdominal pains antiemetic aperitif arthritis cancer colicin children conjunctivitis constipation depurative diarrheadieresis emmenagogue fever flatulence gastralgia gastritisinsomnia irritable colon kidney ailments as a laxativeleucorrhoea liver pain mouth ulcer and stomachache Thisplant has been in use for a long period of time withoutany documented serious adverse effects Studies carriedout in the past and present indicate that fennel possessesdiverse health benefits and are an important constituentof food Studies have shown that various extracts offennel possess a range of pharmacological actions such asantiaging antiallergic anticolitic antihirsutism anti-inflam-matory antimicrobial and antiviral antimutagenic antino-ciceptive antipyretic antispasmodic antistress antithromb-otic anxiolytic apoptotic cardiovascular chemomodulatoryaction cytoprotection and antitumor cytotoxicity diureticestrogenic properties expectorant galactogenic gastrointes-tinal effect hepatoprotective human liver cytochrome P4503A4 inhibitory hypoglycemic hypolipidemic memory-en-hancing property nootropic and oculohypotensive activity

supporting its traditional use However the most prominentand the well studied effects are the antimicrobial andantioxidant effects of essential oil of fennel in differentexperimental models The observed health benefits may becredited to the presence of the various phytochemicals likevolatile compounds flavonoids phenolic compounds fattyacids and amino acids

Fennel also contains mineral and trace elements likealuminum barium calcium cadmium cobalt chromiumcopper ironmagnesiummanganese nickel lead strontiumand zinc [124] fat soluble vitamins such as vitamins A Eand K water soluble vitamins like ascorbic acid thiamineriboflavin niacin and pyridoxine essential amino acidslike leucine isoleucine phenylalanine and tryptophane maycontribute to the myriad health beneficial effects at least inpart

Most of the pharmacological studies were conductedusing uncharacterized crude extracts of fennel It is difficultto reproduce the results of these studies and pinpoint thebioactive compounds Hence there is a need for chemi-cal standardization and bioactivity-guided identification ofbioactive compounds Among several classes of chemicalconstituents identified in fennel volatile components of fen-nel essential oil and phenolic compounds are assumed to bethe main bioactive compounds responsible for the majorityof its pharmacological effects However the vast traditionaluse and proven pharmacological activities of fennel indicatethat an immense scope still exists for its chemical explorationFuture studies should be focused on validating the mecha-nism of action responsible for the various beneficial effectsand also on understanding which plant based compounds areresponsible for the reported effectsThe required informationwhen available will enhance our knowledge and appreciationfor the use of fennel in our daily diet Also the outcomeof such chemical studies may further expand its existingtherapeutic potential

Thus there are many areas of research related to thisplant that need to be further explored to fully recognize itsbeneficial effects for society Factors such as geographical andseasonal variation play an important role in the authentica-tion of the chemical constituents responsible for the activitywhich also can be an area of interest Thus it is incumbenton researchers to fill the huge gap of insufficient knowledgeand create awareness among pharmacologists as well as inves-tigators towards providing better medicinal value derivedfrom this plant This can be fulfilled only by generatinginterest among the research community through writing ofcritical appraisals (paper) and extending the interdisciplinaryresearch area to focused studies on Foeniculum vulgare

41 Antimicrobial and Antiviral Activities Foeniculum vul-gare has been used as an ethnic remedy for the cure ofnumerous infectious disorders of bacterial fungal viral andmycobacterial origin Several studies have been carried outin the past validating its antimicrobial antimycobacterialand antiviral potential (summarized in the Table 9) Duskoet al [91] investigated the antibacterial effect of the aqueousextract of 12 medicinal plants of Apiaceae family includingF vulgare An aqueous extract of the aerial part of Fvulgare inhibited the growth of Agrobacterium radiobacterpv tumefaciensErwinia carotovoraPseudomonas fluorescensand Pseudomonas glycinea (Table 9) An aqueous extract ofseed sample inhibited the growth of Enterococcus faecalisStaphylococcus aureus Escherichia coli Klebsiella pneumo-nia Pseudomona aeruginosa Salmonella typhi Salmonellatyphimurium Shigella flexneri and Bacillus cereus with 13ndash22 22ndash24 14ndash24 20-21 21ndash24 11-12 14ndash18 17ndash18 and 24ndash26mm zone of inhibition respectively [3 4] Gulfraz et al[92] investigated the antibacterial effect of the essential oil aswell as ethanolic and methanolic fruit extracts of F vulgareagainst Bacillus cereus Bacillus megaterium Bacillus pumilus

Bacillus subtilis Escherichia coliKlebsiella pneumoniaMicro-coccus luteus Pseudomonas putida Pseudomonas syringaeand Candida albicans According to the results reported byGulfraz et al [92] essential oil of F vulage had significantantimicrobial activities against some of microorganisms ascompared to the methanolic and ethanolic extracts Thediameters of growth inhibition zone ranged from 14 to 31mm(including the diameter of the disc 6mm) with the highestinhibition zone values observed against Bacillus megaterium(31mm) and Bacillus subtilis (29mm) Roby et al [23]investigated antimicrobial effect of the methanol ethanoldiethyl ether and hexane extracts of seed of F vulgare againsttwo species of Gram negative bacteria (Escherichia coli andSalmonella typhi) two species of Gram positive bacteria(Bacillus cereus and Staphylococcus aureus) one species ofyeast (Candida albicans) and one species ofmold (Aspergillusflavus)Themethanolic extract showedmore effective antimi-crobial activity than the other extracts The results fromthe disc diffusion method followed by measurement ofminimum inhibitory concentration (MIC) indicated thatBacillus cereus and Aspergillus flavus were the most sensitivemicroorganisms tested showing the largest inhibition zonesand the lowest MIC values Least activity was exhibitedagainstEscherichia coli with the smallest inhibition zones andthe highest MIC value [23] Shrivastava and Bhargava [93]investigated the antibacterial effect of the crude chloroformand methanol extract of leaves and flowers of F vulgarealong with Raphanus sativus and Brassica nigrum againstEscherichia coli and Staphylococcus aureus Methanol extractof flower of F vulgare showed significant activity againstEscherichia coli whereas crude and chloroform extractsfailed to exhibit antimicrobial activity against Staphylococcusaureus (Table 9) Among different tested bacterial strains the

methanolic fruit extract of F vulgare inhibited the growthof Staphylococcus aureus and Bacillus pumilus with 1127 and1267mm zone of inhibition respectively [7]

Several studies indicating the antifungal effect of Fvulgare along with antibacterial effect are also reported inthe literature Martins et al [94] investigated the antibacterialand antifungal effects of three essential oils of Portugueseplants namely Foeniculum vulgareMentha spicata and Ros-marinus officinalis against Staphylococcus aureus Escherichiacoli Klebsiella pneumonia Pseudomona aeruginosa Staphy-lococcus epidermidis Candida albicans and phytopathogenic

diseases [97] In an in vitro study aqueous and alcoholicseed extracts of F vulgare exhibited inhibitory effect againstAlternaria alternata Mucor rouxii and Aspergillus flavus[98] Interestingly aqueous seed extract of F vulgare showedstrongest antifungal activity as compared to reference fungi-cidal agent that is griseofulvin [99]

All of the above mentioned studies were carried outon the crude extracts and it is difficult to pinpoint theactive antimicrobial metabolite A phenylpropanoid deriva-tive called dillapional characterized from F vulgare stem wasfound to be an antimicrobial constituent with MIC values of125 250 and 125 against Bacillus subtilis Aspergillus nigerand Cladosporium cladosporioides respectively A coumarinderivative scopoletin was also isolated as a marginallyantimicrobial agent [100] The characterization of sevendifferent types of oxygenatedmonoterpenes frommethylene

chloride crude extract of F vulgare [101] suggested thatthe crude extract containing monoterpenes could be a newmedicinal resource for antibacterial agents

A total of 78 compounds were identified from theactive antimycobacterial fraction of F vulgare with thehelp of gas chromatography-mass spectra (GC-MS) Outof these twenty compounds were tested against one sensi-tive and three MDR strains of Mycobacterium tuberculosisusing the Alamar Blue microassay Compounds that showedsome degree of antimycobacterial activity against all strainstested were the following linoleic acid (MIC 100 120583gmL)oleic acid (MIC 100 120583gmL) 13-benzenediol (MIC 100ndash200120583gmL) undecanal (MIC 50ndash200120583gmL) and 24-undecadienal (MIC 25ndash50120583gmL) 24-Undecadienal wasthe most active compound against multidrug resistant Mtuberculosis speciesThus the dietary intake of F vulgaremaylower the risk ofM tuberculosis infection [63]

Orhan et al [5] studied the antiviral activity of theessential oil of fruit sample of F vulgare along with 12other Turkish medicinal plants against the DNA virusHerpessimplex type-1 (HSV-1) and the RNA virus parainfluenzatype-3 (PI-3) Most of the oils and compounds displayedstrong antiviral effects against HSV-1 ranging between 08and 0025 120583gmL However the samples tested were lesseffective against PI-3 with results ranging between 16 and02 120583gmL Only the essential oils of Anethum graveolensFoeniculum vulgare (fully mature) Mentha piperita Menthaspicata Ocimum minutiflorum Ocimum vulgaris and Sat-ureja cuneifolia inhibited this virus significantly

All these literature findings validated the traditional usesof Foeniculum vulgare in infectious disorders like abdomi-nal pains antiemetic arthritis conjunctivitis constipationdepurative diarrhea dieresis fever flatulence gastralgia gas-tritis insomnia irritable colon mouth ulcer stomachacherespiratory disorders skin diseases and so forth There isalways a need for new antimicrobial agents due to rapiddevelopment of resistance Bioactive metabolites of F vulgaremay be a potential source for new antimicrobial agents

42 Anti-Inflammatory Activity Oral administration ofmethanol extract of F vulgare fruit to rat and mice exhibitedinhibitory effects against acute and subacute inflammatorydiseases The anti-inflammatory activity of methanol extractwas evaluated by using three screening protocols namelycarrageenan-induced paw edema arachidonic acid-inducedear edema and formaldehyde-induced arthritis Theseare widely used for testing nonsteroidal anti-inflammatorydrugs For acute inflammationmethanol extract (200mgkg)exhibits significant inhibition of paw edema (69) inducedby carrageenan injection as compared to the control groupof animals Methanol extract of F vulgare also inhibitsear-edema (70) induced by arachidonic acid in mice Thelevel of serum transaminase aspartate aminotransferase(AST) and alanine aminotransferase (ALT) significantlyincreases in the presence of methanolic extract of F vulgareon inflammation induced by formaldehyde as comparedto control group The assessment of the level of AST and

ALT provides a good and simple tool to measure the anti-inflammatory activity of the target compounds [102] Theseoverall results seem to suggest that F vulgare FME mayact on both the cyclooxygenase and lipoxygenase pathways[79]

43 Antiallergic Activity Methanolic extract of F vulgarefruit showed significant inhibitory effect on DNFB- (24-dinitrofluorobenzene-) induced delayed type hypersensitiv-ity after oral administration of 200mgkg once a day for7 days The inhibitory effect on immunologically inducedswelling suggests the possible immunosuppressive propertiesof F vulgare [79]

44 Hepatoprotective Activity Essential oil of F vulgareseeds revealed a potent hepatoprotective effect against acutehepatotoxicity produced by carbon tetrachloride in ratsOral administration of F vulgare essential oil decreases thelevels of serum aspartate aminotransferase (AST) alanineaminotransferase (ALT) alkaline phosphatase (ALP) andbilirubin as compared to the control group Ozbek et alsuggest that the constituents (d-limonene and 120573-myrcene) ofessential oil may have played a key role in the protection ofliver from CCl

4toxicity [9]

45 Anxiolytic Activity Anxiety is the unpleasant feeling offear and concern When anxiety becomes excessive it maybe considered as an anxiety disorder Anxiolytic fennel isa drug used for the treatment of anxiety and its relatedpsychological and physical symptoms Naga Kishore et al[89] investigated the anxiolytic activity of ethanolic extract ofF vulgare fruit with the help of elevated plus maze rota rodopen field test and whole board models The 100 to 200mgdose of extract per kg of body weight of animal revealedsignificant activity when compared to reference anxiolyticdrug called diazepam (1mgkg) Thus fennel extract maypossess anxiolytic activity supporting its traditional claimabout anxiolytic activity reported in 19th edition of Pharma-cology and Pharmacotherapeutics by Sathodkar Bhandarkarand Rege

46 Antistress Activity Drug and food of natural originplay a significant role in public healthcare systems and arebeing investigated as remedies for a number of stress-relateddisorders [103]Thewhole plant extract of F vulgare exhibitednotable antistress effect against stress induced by forcefulswimming of test animals The key parameters that isurinary levels of vanillyl mandelic acid (VMA) and ascorbicacid in rats were used to evaluate antistress activity Theplant extract (50 100 and 200mgkg body weight) showeda significant improvement in urinary levels of VMA (119875 lt0001) and ascorbic acid excretion levels (119875 lt 0001) in testanimals when compared to the normal basal levels in controlgroup of animalsThus the extract of entire plant of F vulgareacts as an antistress agent [13]

47 Memory-Enhancing Property There are a number ofplants whose consumption is believed to enhance memory

22 BioMed Research International

and intelligence These were usually given to children as partof their food F vulgaris an ayurvedic rasayana (mixture)possessing multiple neuropharmacological activities Theantidepressant activity of fennel has been well documentedin ethnomedicine The whole plants extract (50 100 and200mgkg) of F vulgare exhibited memory-enhancing effectagainst scopolamine-induced amnesic rats This experimentwas evaluated by conditioned avoidance response (CAR)technique The CAR of rats administered with the extractincreased gradually to 95 over 7 to 12 days The acquisition(time to achieve 95 CAR) for rats administered with theextract was dose- and time-dependent compared to controlgroup which took 12 days for acquisition The percentavoidance was always higher in the extract-treated groupsas compared to control group Animals receiving 200mgkgbody weight of the extract took ten days while groups treatedwith 100 and 50mgkg doses of the extract required elevenand twelve days respectively to reach the point of acquisitionAdministration of scopolamine produced amnesia as seenfrom reduction in the observed CAR Amnesia was greaterin the control group than in extract-treated groups How-ever continued treatment with F vulgare produced betterretention and recovery in a dose-dependent manner thanthe vehicle-treated animals Recovery from scopolamine-induced amnesia in the extract-treated groups took 3ndash5 dayswhen compared to normal (control) group which took over6 days This overall progress suggests that F vulgare extractpossesses memory-enhancing property [13]

48 Nootropic Activity Alzheimerrsquos disease is a neurode-generative disorder associated with a decline in cognitiveabilities Dementia is one of the age-related mental problemsand a characteristic symptom of Alzheimerrsquos disease Thereis some evidence in favor of use of F vulgare for the treat-ment of cognitive disorders like dementia and Alzheimerrsquosdisease Methanol extract of the whole plant of F vul-gare administered for eight successive days ameliorated theamnesic effect of scopolamine and aging-induced memorydeficits inmiceThis extract increased step-down latency andacetylcholinesterase inhibition in mice significantly Thus Fvulgaremay be employed in treatment of cognitive disorderssuch as dementia and Alzheimerrsquos disease as a nootropic andanticholinesterase agent [80]

49 Antihirsutism Activity Idiopathic hirsutism is definedas the occurrence of excessive male pattern hair growth inwomen who have a normal ovulatory menstrual cycle andnormal levels of serum androgens It may be a disorder ofperipheral androgen metabolism Traditionally Foeniculumvulgare has been used as an estrogenic agent It has beenreputed to increase milk secretion promote menstruationfacilitate birth and increase libido On considering aboveaspect Javidnia and his research team evaluated the antihir-sutism activity of ethanolic extract of F vulgare seed againstidiopathic hirsutism by preparing cream containing 1 and 2of fennel extract The efficacy of treatment with the creamcontaining 2 fennel is better than the cream containing 1fennel and these two were more potent than placebo (control

group) The mean values of hair diameter reduction were78 183 and minus05 for patients receiving the creamscontaining 1 2 and 0 (placebo) respectively [78]

410 Estrogenic Properties Since the discovery of the estrusinducing effects of some plant products in 1926 consider-able effort has been devoted towards the characterizationof phytoestrogens including flavonoids isoflavonoids chal-cones coumestans stilbenes lignans saponins and essentialoils [16] F vulgare has estrogen-like activity In male ratstotal concentration of protein was found to be significantlydecreased in testes and in vasa deferentia whereas increasedin seminal vesicles and in prostate gland On the otherhand simultaneous decrease in the activities of acid andalkaline phosphatase in all these regions (except that alka-line phosphatase was unchanged in vasa) due to the oraladministration of acetone extract of F vulgare fruit wasobserved In female rats oral administration of the extract for10 days led to vaginal cornification and oestrus cycle [8] Totalconcentration of nucleic acids and protein as well as the organweights increased in both the tissues namely mammaryglands and oviducts due to the oral administration of acetoneextract (50 150 and 250120583g100 g body wt) of F vulgare seeds[104] Fennel oil was reported to exhibit estrogenic activitypromote menstruation and alleviate the symptoms of femaleclimacteric and increase libido [71] Administration of fenneloil (25 and 50 120583gmL final concentration in the organ bath)failed to exhibit any remarkable effect in uterine contrac-tion While 10 20 and 40 120583gml concentration of fennel oilrevealed significant inhibitory effect against prostaglandinE2 Fennel oil significantly reduces the frequency of uterinecontraction induced by prostaglandin E2 Thus the extractsof F vulgare have strong estrogenic activity [76]

411 Galactogenic Activity Foeniculum vulgare has been usedformillennia to increasemilk secretion [105]Thus F vulgarebelongs to galactagogue substance Structural similarity ofits main constituent anethole to dopamine seems to beresponsible for galactogenic activityDopamine acts to inhibitthe secretion of the milk-producing hormone prolactinAnethole might influence milk secretion by competing withdopamine at the appropriate receptor sites thereby inhibitingthe antisecretory action of dopamine on prolactin [71] It wasreported that anol (demethylated anethole) causes growthof the lobule-alveolar system in the mammary glands ofimmature female rabbits and induces menstruation in miceand other experimental animals Anol also gave positiveresults in the Jadassohn nipple test a test which involvesthe measurement of changes induced in the nipples ofguinea pigs subjected to the cutaneous application of sexhormones However further research suggests that the actualpharmacologically active agents responsible for galactogenicactivity are polymers of anethole such as dianethole andphotoanethole rather than anol or anethole itself [20 76]

412 Expectorant Activity F vulgare seeds stimulate theciliary motility of the respiratory apparatus and enhance the

BioMed Research International 23

external transport of extraneous corpuscles This action sug-gests a use for fennel in treating bronchial and bronchopul-monary afflictions and in particularly polluted environments[106] The volatile oil of F vulgare stimulates the contractionof the smooth muscles of the trachea an action that couldfacilitate the expectoration of mucus bacteria and othercorpuscles extraneous to the respiratory tracts [74]

413 Anticolitic Activity Essential oil of fennel regulates themotility of smooth muscles of the intestine while at thesame time reducing intestinal gas Alone or combined withother plant medicinals Foeniculum vulgare is indicated in thetreatment of spastic gastrointestinal disturbances in someforms of chronic colitis (which resist other treatments) indyspepsias from gastrointestinal atony in dyspepsias withthe sensation of heaviness in the stomach and so forthTheaddition of fennel to preparations containing anthraquinoniccomponents reduces the occurrence of abdominal pain oftenassociated with this type of laxative [73]

414 Antinociceptive Activity Antinociceptive means anysubstance that inhibits nociception which is a physiologicalprocess underlying the sensation of pain Briefly it reducesthe sensitivity to painful stimuli The various extracts ofaerial part of F vulgare namely hexane methylene chlorideethyl acetate and methanolic extract showed remarkableantinociceptive activity against acetic acid induced writhingin mice [68] The methanolic extract of the aerial parts ofF vulgare exhibited the highest antinociceptive activity at adose level of 2000mgkg while the activity exhibited by theethyl acetate extract was at dose level 800mgkgOn the otherhand n-hexane extract (700mgkg) and methylene chlorideextract (500mgkg) exhibited similar antinociceptive activi-ties being less than peripheral antinociceptive reference drug(acetyl salicylic acid) [68]

415 Diuretic Activity A diuretic is any substance thatpromotes the production of urine Briefly it is an agentthat promotes diuresis Diuretics work by promoting theexpulsion of urine (measured as the urine volume [UV]excreted) and urinary sodium (UNa) from the body and thishelps reduce the volume of blood circulating through thecardiovascular system Caceres et al [107] performed a studyin conscious animals and administered a powdered extractof the whole plant (F vulgare) which had no effect on UVor UNa The ethanolic extract of F vulgare fruit revealedexcellent diuretic activity and proves the earlier folk claimof F vulgare which was reported in the United State ofAmerica (Table 5) The fruit extract showed statistically ahighly significant diuretic effect F vulgare induced diuresis(500mgkg dose)was comparable to that of reference diureticagent urea (960mgkg dose) in mice with a urine outputthat was almost double that of the control group Thediuresis was not associated with changes in sodium andorpotassium excretion [108] In another part of the study theauthors showed that Foeniculum vulgare had little effect onthe noradrenalin contractile responses of aortic rings thus

suggesting that it worked mainly as a diuretic and natriureticwith little effect on arterial vascular tone [77]

416 Cardiovascular Activity An aqueous extract of F vul-gare leaves possesses potential cardiovascular action Thiseffect was investigated using pentobarbital-anaesthetisedmale albino Sprague-Dawley rats [75] An intravenousadministration of the lyophilized boiled water extract ofleaves produced a significant dose-related reduction in arte-rial blood pressure without affecting the heart rate or respi-ratory rate On the other hand the nonboiled aqueous extractshowed very little hypotensive activityThe hypotensive effectof the boiling water extract appeared not to be mediated viaadrenergicmuscarinic ganglionic or serotonergic receptorshowever histamine antagonists inhibited the hypotensiveeffect in a dose-related manner [75]

417 Oculohypotensive Activity The aqueous seed extract ofF vulgare demonstrated significant oculohypotensive activityusing water loading and steroid induced glaucoma modelThis extract exhibited 1749 2116 and 2203 reduction ofintraocular pressure in normotensive rabbits at 03 06and 12 (wv) concentrations respectively A maximummean difference of 3120 was observed between vehiclestreated and extracts treated eyes in water loading experi-mental animal model while a maximum mean intraocularpressure lowering of 3129 was observed in steroid inducedmodel of glaucoma Thus the aqueous extract of F vulgarerevealed oculohypotensive activity which was found to be asgood as that of reference standard antiglaucoma drugs calledtimolol [84]

418 Antithrombotic Activity Tognolini et al [55] providedevidence of potent inhibitory activity of essential oil of F vul-gare against platelet aggregation induced byADP arachidonicacid and collagen in guinea pig plasma Similar findingswere reported by Yoshioka and Tamada [109] for aggregationof rabbit platelets by an aromatic factor of fennel oil Theessential oil and anethole (a constituent of oil) of F vulgaretested in vitro in rat aorta with or without endotheliumdisplayed comparable NO-independent vasorelaxant activityat antiplatelet concentrations It supports the safety of Fvulgare that is free from cytotoxic effects Anethole and Fvulgare did not cause cytotoxicity when incubated for 30minupto 300 120583gmL in platelet viability test This concentrationwas largely compatible with those adopted in the functionalin vitro tests In vivo both F vulgare essential oil andanethole orally administered in a subacute treatment to mice(30mgkgday for 5 days) showed significant antithrom-botic activity preventing the paralysis induced by collagen-epinephrine intravenous injection (70 and 83 protectionresp)Thus essential oil and its main component anethole ofF vulgare showed a safe antithrombotic activity in guinea pigplasma that seems due to their broad spectrum antiplateletactivity clot destabilizing effect and vasorelaxant action [55]

419 Antimutagenic Effect Essential oil of F vulgare revealednoteworthy protective effects against genotoxicity in mice

induced by cyclophosphamide Genotoxicity and cytotoxicitywere assessed by using mice bone marrow chromosomalaberration micronucleus and sperm abnormality assaysrespectively Oral administration of essential oil (1 and2mLkg) significantly inhibited the frequencies of aberrantmetaphases chromosomal aberrations micronuclei forma-tion and cytotoxicity in mouse bone marrow cells inducedby cyclophosphamide and also produced a significant reduc-tion of abnormal sperm and antagonized the reduction ofcyclophosphamide induced superoxide dismutase catalaseand glutathione activities and inhibited increased malondi-aldehyde content in the liver Additionally F vulgare inhibitsthe oxidative stress induced by cyclophosphamide [90]

420 Gastrointestinal Effect Theaqueous extract of F vulgareshowed remarkable antiulcerogenic effect against ethanol-induced gastric lesions in rats It was found that pretreatmentwith aqueous extract significantly reduced ethanol-inducedgastric damageThis effect of aqueous extract was highest andstatistically significant in 300mgkg group comparedwith thecontrol (119875 lt 0001) group of animal Additionally aqueousextract of F vulgare significantly reduced the whole bloodmalondialdehyde levels while significantly increased nitritenitrate ascorbic acid retinol and beta-carotene levels Thusaqueous extract of F vulgare fruit had clearly a protectiveeffect against ethanol-induced gastric mucosal lesion in rats[81]

421 Chemomodulatory Action The chemopreventive effectof different doses of test diet of Foeniculum vulgare seeds wasexamined against 712-dimethylbenz(a)anthracene- (DMBA-) induced skin papillomagenesis and benzo(a)pyrene-[B(a)P-] induced forestomach papillomagenesis at the peri-initiational level in Swiss albino mice Fennel seeds exhibita significant reduction in the skin and the fore-stomachtumor incidence and tumor multiplicity as compared tothe control group Further biochemical assays showeda significant increase in the contentactivities of phase Ienzymes especially in the case of 6 test diet A concomitantincrease in the activities of the phase II enzymes wasobserved with all the doses of test diet under study Asignificant enhancement in the activities of antioxidantenzymes was observed especially at 4 and 6 test diets offennel These findings were indicative of chemopreventivepotential of fennel against carcinogenesis This is the firstreport showing chemopreventive potential of seeds of fennelagainst carcinogenesis [85]

422 Cytoprotection and Antitumor Activity Anethole is theprincipal active component of fennel seeds which has exhib-ited anticancer activity Al-Harbi et al studied the antitumoractivity of anethole against Ehrlich ascites carcinoma inducedin a tumor model in Swiss albino mice The study revealedthat anethole increased survival time reduced tumor weightand reduced the volume and body weight of the Ehrlichascites tumour-bearing mice It also produced a significantcytotoxic effect in the Ehrlich ascites tumour cells in the pawreduced the levels of nucleic acids and malondialdehyde and

increased glutathione concentrations [110] In vitro cytopro-tection activity of methanolic extract of Foeniculum vulgarewas evaluated against normal human blood lymphocytes bymicronucleus assay and antitumor activity against B16F10melanoma cell line by Trypan blue exclusion assay for cellviability Lymphocyte culture treated with 70 methanolicextract of Foeniculum vulgare showed very less percentage ofmicronucleus that is 0006 as compared to standard drugdoxorubicin which showed 0018 micronucleus On theother hand 70methanolic extract of Foeniculum vulgare haspotent antitumor activity at the concentration of 200120583gmLThe results suggest that the Foeniculum vulgare could beconsidered as a natural resource of antitumor agents as wellas cytoprotective to normal cells [11]

423 Cytotoxicity Kaileh and his coworker investigated thecytotoxic effect of organic extracts of 24 selected Palestinianmedicinal plant species The plant selection was based onexisting ethnobotanic information and interviews with localhealers The extracts of the plants under investigation weretested for their potential antitumor (cytotoxic) effect on themurine fibrosarcoma L929sA cells and on the human breastcancer cells MDA-MB231 and MCF7 The extract from Fvulgare presented an IC (50) value at 24 h of 700 plusmn 28 and500plusmn17 120583gmL on L929sA andMCF7 cells respectivelyThenuclear transcription factor NFkappaB or NF120581B regulatesthe expression of various genes They further investigatedthe effect of nine promising plant extracts withheld fromthe first cell viability screening on NF120581B activation Thedichloromethane and methanol (1 1) extract of aerial part ofF vulgare revealed immunomodulatory NF120581B activities [82]Also Berrington and Lall investigated the in vitro cytotoxicityof acetone extracts of F vulgare and other eight medicinalplants against a noncancerous African green monkey kidney(Vero) cell line and an adenocarcinoma cervical cancer(HeLa) cell line [87]

424 Antipyretic Activity F vulgare extract showedantipyretic activity against hyperpyrexia in mice It wasinduced by SC administration of 2mL100 g of a 20aqueous suspension of brewerrsquos yeast As an antipyreticagent ethanolic extract of F vulgare fruit showed a moderateantipyretic activity that was statistically significant after 30and 90min (119875 lt 001) [108]

425 Hypolipidemic Activity The aqueous extract of F vul-gare revealed notable hypolipidemic and antiatherogenicactivity against Triton WR-1339 induced hyperlipidemiain mice Aqueous extract causes significant reduction ofplasma lipid levels that is cholesterol triglycerides LDL-cholesterol and apolipoprotein-B decreased by 40 2361 and 61 respectively and increase in HDL-cholesteroland apolipoprotein A1 by 85 and 58 respectively [88]

426 Hypoglycemic Activity The essential oil of F vulgareexhibits potential hypoglycemic and antioxidant activityagainst streptozotocin induced diabetes in rats Essentialoil (30mgkg body weight) of F vulgare works in the

427 Antispasmodic Activity The antispasmodic activity of25 and 100mLL of alcoholic extract of Foeniculum vulgarealong with other Germanic medicinal plants namelyMelissaofficinalis Rosmarinus officinalisMentha piperitaMatricariachamomilla Carum carvi and Citrus aurantium were testedemploying the guinea pig ileum and using acetylcholine andhistamine as spasmogens An alcoholic extract of the fruits ofFoeniculum vulgare possesses antispasmodic activity whichinhibits the acetylcholine and histamine-induced guineapig ileal contractions in vitro An essential oil which isobtained from the fruits of Foeniculum vulgare 25 120583gmL and10 120583gmL respectively inhibited oxytocin and prostaglandin[72]

428 Apoptotic Activity The apoptotic activities of ethanolextracts from fruits of seven species of Apiaceae familynamely Eryngium planum Archangelica officinalis Pasti-naca sativa Heracleum sibiricum Carum carvi Foenicu-lum vulgare and Levisticum officinale against ML-1mdashhumanacute myeloblastic leukaemia J-4501mdashhuman acute Tcell leukaemia EOLmdashhuman eosinophilic leukaemia HL-60mdashhuman Caucasian promyelocytic leukaemia 1301mdashhuman T cell leukaemia lymphoblast C-8166mdashhuman Tcell leukaemia U-266B1mdashhuman myeloma WICLmdashhumanCaucasian normal B cell and H-9mdashhuman T cell wereinvestigated with the help of Trypan blue assay and AnnexinV fluos assay [86] The ethanol extract from fruit F vulgareshowed the highest mortality in Trypan blue test for J45cell linemdash4 of viable cells and for C8166 cell linemdash100of mortality However the cells of other lines showed thehighest viability HL60mdash60 EOLmdash48 and MLmdash1ndash42The normal cell line H9 and WICL showed 35 and 25of viable cells respectively C8166 cell line and J-45 cell lineshowed the highest level of the apoptotic cells detected byAnnexin V methodmdash100 and 93 respectively Howeverthe cells of two lines HL60 and EOL-1 showed the lowerlevels of apoptotic cellsmdash52 and 60 respectively Highpercentage of apoptotic cells was observed inH9 andWICLmdash76 and 93 respectively [86]

429 Human Liver Cytochrome P450 3A4 Inhibitory ActivityThirteen compounds isolated from the methanolic extract offennel have been found to possess human liver cytochromeP450 3A4 inhibitory activity Among these compounds 5-methoxypsoralen (5-MoP) showed the strongest inhibitionwith an IC50 value of 183120583m and with a mixed type ofinhibition [83]

430 Antiaging Effects Rasul and his coworker developeda base and formulation containing 4 concentrated seedextract of F vulgare This formulation shows notable antiag-ing effect with supporting experimental data related to skinmoisture and transepidermal water loss (TEWL) The basewas insignificant while the formulation showed significanteffects on skin moisture and TEWL The texture parameterenergy showed a significant increase proving that the formu-lation possesses potential antiaging effects [50]

431 Bronchodilatory Effect Ethanol extract and essential oilfrom F vulgare exhibited bronchodilatory activity on con-tracted tracheal chains of guinea pig The potassium channelopening effect of fennel may contribute on its relaxant effecton guinea pig tracheal chains [111] Moreover anethole bearsa striking resemblance to the catecholamines epinephrinenorepinephrine and dopamine This structural similarityappears to be responsible for the various sympathomimeticactivities of F vulgare such as bronchodilatory effect [71]

432 Antioxidant Activities Naturally occurring antioxi-dants can be used to protect human beings from oxidativestress damage [112] Fennel was known as excellent source ofnatural antioxidants and contributed to the daily antioxidantdiet [113]Wild fennel was found to exhibit a free radical scav-enging activity with higher content phenolic and flavonoidthan medicinal and edible fennel and the aerial parts ofthe Italian fennel populations showed the highest DPPHscavenging activity [65] Phenolic compounds of fennelincluding caffeoylquinic acid rosmarinic acid eriodictyol-7-orutinoside quercetin-3-O-galactoside and kaempferol-3-O-glucoside showed antioxidant activities [67] The volatileoil showed strong antioxidant activity in comparison withbutyrated hydroxyanisole and butylated hydroxytolueneEthanol and water extracts of fennel showed less antioxidantactivity compared with essential oil [114]

5 Environmental Application

Foeniculum vulgare that is fennel not only exhibited phar-macological activities but also revealed a few environmentalactivities These activities play a key role in the managementof nematode insect mosquitoes and some harmful larvae ofmalaria producing vector Thus the extracts of F vulgare andisolated biologically active compounds have been evaluatedfor their insecticidal repellent acaricidal larvicidal andnematicidal activity [115ndash119] A brief review on the differenttype of ecofriendly environmental activities as reported onthis plant is summarized below

51 Insecticidal Activities The fruit derived phytoconstitu-ents of F vulgare exhibited prominent insecticidal activi-ties against Sitophilus oryzae Callosobruchus chinensis andLasioderma serricorne This activity was examined usingdirect contact application and fumigation methods Thebiologically active constituents that is phenylpropenes (E)-anethole and estragole and the monoterpene (+)-fenchonewere characterized from Foeniculum fruit By using a filter

26 BioMed Research International

paper diffusion test estragole (0168mg cmminus2) caused 91mortality to S oryzae within 1 day after treatment whereas(+)-fenchone and (E)-anethole gave over 90 mortality at 2and 4 day after treatment respectively

After 2 days of treatment all test compounds (0021mg cmminus2 concentration) revealed potent insecticidal activityagainst C chinensis Whereas after 1 day of treatment (E)-anethole (0105mg cmminus2) gave 100mortality of L serricornewhereas 90 and 60 mortality at 4 day after treatment wasachieved with estragole and (+)-fenchone respectively In afumigation test the compounds were much more effectiveagainst adults of S oryzae C chinensis and L serricorne inclosed cups than in open ones indicating that the insecticidalactivity of test compounds was largely attributable to fumi-gant action As naturally occurring insect-control agents theF vulgare fruit-derived materials described could be usefulfor managing field populations of S oryzae C chinensis andL serricorne [116]

52 Acaricidal Activity Fennel oil shows significant acaricid-al activity againstDermatophagoides farinae andDermatoph-agoides pteronyssinus (+)-fenchone and p-anisaldehyde aremajor constituents of fruit oil of F vulgare P-anisaldehydewas the most toxic compound against D farinae and is muchmore effective compared with benzyl benzoate thymol andestragol [118]

53 Repellent Activity The methanolic extract of fruits ofF vulgare was spectroscopically characterized for the pres-ence of biologically active constituents called (+)-fenchoneand (E)-9-octadecenoic acid The repellent activity of theseconstituents was tested against hungry Aedes aegypti femaleswith the help of skin and patch tests and compared withthat of the commercial repellent agent called NN-diethyl-m-toluamide (DEET) and (Z)-9-octadecenoic acid In askin test with female mosquitoes (+)-fenchone and (Z)-9-octadecenoic acid (04mgcm2) exhibitedmoderate repellentactivity at 30min after treatment whereas DEET providedgt1 h of protection against adult mosquitoes at (02mgcm2)Thus (+)-Fenchone and (E)-9-octadecenoic acid are poten-tial mosquito repellent agents or lead compounds [117]

54 Larvicidal Activity Plant extracts and oils may act asalternatives to conventional pesticides for malaria vectorcontrol By considering this aspect Sedaghat et al [119] inves-tigated the larvicidal activity of essential oils of three plantsof Apiaceae family against malaria vector called Anophe-les stephensi The larvicidal activity was evaluated againstlaboratory-reared larvae by standard method of WHO TheF vulgare oil was the most effective against A stephensiwith LC(50) and LC(90) values of 2010 and 4451 ppmrespectively [119] Additionally the essential oil extracts fromleaves flowers and roots of F vulgare exhibit noticeablelarvicidal activity against fourth-instar larvae of themosquitoCulex pipiens molestus Terpineol and 18-cineole content of Fvulgare are the most effective phytoconstituent against Culexpipiens molestus bites offering complete protection for 16 and2 h respectively [120] Recently Zoubiri et al [57] reported

the larvicidal activity of essential oil of fennel seed againstCulex pipiensmosquitoThus F vulgare can serve as a naturallarvicidal agent

55 Nematicidal Activity Oka et al investigated the in vitronematicidal activity of essential oils extracted from 27 spicesand aromatic plants in pot experiments Twelve of thetwenty-seven essential oils immobilized more than 80 ofjuveniles of the root-knot nematodeMeloidogyne javanica ata concentration of 1000 120583Lliter At this concentration mostof these oils also inhibited nematode hatching Essential oilsof Carum carvi Foeniculum vulgare Mentha rotundifoliaand Mentha spicata showed the highest nematicidal activityamong the in vitro tested oils In 3-liter pot experimentsnematicidal activity of the essential oils and their componentswas confirmed at 200 and 150mgkg respectivelyThe resultssuggest that the essential oils and theirmain componentsmayserve as nematicides [115]

The long history of ethnomedicinal application with noreports of any serious side effects suggests that F vulgarecould be considered as safe Inmost toxicity experiments car-ried out on F vulgare no sign of toxicity was observed Shahand his coworker in 1991 investigated the detailed toxicityaccount of ethanolic extract of fennel fruit in experimentalmice with respect to acute and 90 days longer term toxicity[121] In experimentation Shah and his coworker observedthe general symptoms of toxicity and mortality for only 24 hin acute toxicity Whereas in another part of toxicity theystudied the effect of fennel extract on mice with 90 dayslong term treatment Acute toxicity of ethanolic extract of Fvulgarewas assessed in 35mice by using three concentrationsnamely 05 1 and 3 gkg body weight In this investigation Fvulgare exhibited no signs of toxicity and no mortality wasobserved upto the dose level 3 gkg body weight In case oflonger term toxicity ethanolic extract of F vulgare (100mgkgbody weightday) was given in drinking water of animals(30 male and 30 female mice) All external morphologicalhaematological and spermatogenic changes in addition tobody and vital organ weights were recorded The extractcaused no significant chronic mortality as compared tocontrols during this investigation The treated male micegained significant weight during chronic treatment while aloss or no significant change in weight was noticed in thefemale mice treated with the same extract The extracts didnot show spermatotoxic effects Thus Shah and his coworkerconcluded that fennel extract is safe based on both acuteandor long term toxicity studies [121] Additionally the plantextract in doses of 05 1 and 3 gkg (orally) did not causeany deaths These doses do not show any type of toxicityagainst several parameters tested namely locomotor activitybizarre reactions sensitivity to sound social interaction tailposture aggressive behaviour ataxia paralysis convulsionstremors prostration exophthalmos pupil size defecationsalivation urination pattern of respiration nasal dischargecyanosis and piloerection Exceptionally only the 3 gkg dose

showed signs of reduced locomotor activity and piloerec-tion Otherwise all other parameters were negative [108]In another experiment of acute toxicity different solventextracts namely n-hexane methylene chloride ethyl acetateand methanol extracts of F vulgare upto 55 gkg concentra-tion did not revealed any kind of toxicity in mice LD50being 675 110 692 and 15 gkg for n-hexane methylenechloride ethyl acetate and methanol extracts respectively[68] The plant extract of F vulgare was administered orallyat a dose of 100 200 400 600 800 1000 and 2000mgkgof body weight of mice Each group of animals was undervisual observation for 10 days for the external behavior ofneurological toxicity created by plant extract Even the micereceiving highest dose of F vulgare extract did not show anymortality or toxicity demonstrating the safety profile of theplant extract [89]

The acute oral 50 LD50 for anethole in rats was foundto be 2090mgkg Repeated doses of one-third the LD50 ofanethole (695mgkg) given to rat caused mild liver lesionsIt would therefore appear that in normal therapeutic dosagesanethole would have minimal hepatotoxicity When anetholewas fed to rats daily for one year as 025 of the dietno hepatic damage was seen [122] The acute oral LD50 ofessential oil in rats is 1326mgkg [76] The use of F vulgareessential oil as a remedy for control of primary dysmenorrheaincreases concern about its potential teratogenicity due toits estrogen like activity Evaluation of teratogenicity ofessential oil using limb bud mesenchymal cells showed thatthe essential oil may have toxic effect on fetal cells butthere was no evidence of teratogenicity upto concentrationof 93mgmL of culture medium [123] The overall toxicitystudies carried out on F vulgare accounts for its safety at therecommended therapeutic doses

7 Conclusions

The available scientific research on Foeniculum vulgarehas shown that it is an important medicinal plant used ina wide range of ethnomedical treatments especially forabdominal pains antiemetic aperitif arthritis cancer colicin children conjunctivitis constipation depurative diarrheadieresis emmenagogue fever flatulence gastralgia gastritisinsomnia irritable colon kidney ailments as a laxativeleucorrhoea liver pain mouth ulcer and stomachache Thisplant has been in use for a long period of time withoutany documented serious adverse effects Studies carriedout in the past and present indicate that fennel possessesdiverse health benefits and are an important constituentof food Studies have shown that various extracts offennel possess a range of pharmacological actions such asantiaging antiallergic anticolitic antihirsutism anti-inflam-matory antimicrobial and antiviral antimutagenic antino-ciceptive antipyretic antispasmodic antistress antithromb-otic anxiolytic apoptotic cardiovascular chemomodulatoryaction cytoprotection and antitumor cytotoxicity diureticestrogenic properties expectorant galactogenic gastrointes-tinal effect hepatoprotective human liver cytochrome P4503A4 inhibitory hypoglycemic hypolipidemic memory-en-hancing property nootropic and oculohypotensive activity

supporting its traditional use However the most prominentand the well studied effects are the antimicrobial andantioxidant effects of essential oil of fennel in differentexperimental models The observed health benefits may becredited to the presence of the various phytochemicals likevolatile compounds flavonoids phenolic compounds fattyacids and amino acids

Fennel also contains mineral and trace elements likealuminum barium calcium cadmium cobalt chromiumcopper ironmagnesiummanganese nickel lead strontiumand zinc [124] fat soluble vitamins such as vitamins A Eand K water soluble vitamins like ascorbic acid thiamineriboflavin niacin and pyridoxine essential amino acidslike leucine isoleucine phenylalanine and tryptophane maycontribute to the myriad health beneficial effects at least inpart

Most of the pharmacological studies were conductedusing uncharacterized crude extracts of fennel It is difficultto reproduce the results of these studies and pinpoint thebioactive compounds Hence there is a need for chemi-cal standardization and bioactivity-guided identification ofbioactive compounds Among several classes of chemicalconstituents identified in fennel volatile components of fen-nel essential oil and phenolic compounds are assumed to bethe main bioactive compounds responsible for the majorityof its pharmacological effects However the vast traditionaluse and proven pharmacological activities of fennel indicatethat an immense scope still exists for its chemical explorationFuture studies should be focused on validating the mecha-nism of action responsible for the various beneficial effectsand also on understanding which plant based compounds areresponsible for the reported effectsThe required informationwhen available will enhance our knowledge and appreciationfor the use of fennel in our daily diet Also the outcomeof such chemical studies may further expand its existingtherapeutic potential

Thus there are many areas of research related to thisplant that need to be further explored to fully recognize itsbeneficial effects for society Factors such as geographical andseasonal variation play an important role in the authentica-tion of the chemical constituents responsible for the activitywhich also can be an area of interest Thus it is incumbenton researchers to fill the huge gap of insufficient knowledgeand create awareness among pharmacologists as well as inves-tigators towards providing better medicinal value derivedfrom this plant This can be fulfilled only by generatinginterest among the research community through writing ofcritical appraisals (paper) and extending the interdisciplinaryresearch area to focused studies on Foeniculum vulgare

41 Antimicrobial and Antiviral Activities Foeniculum vul-gare has been used as an ethnic remedy for the cure ofnumerous infectious disorders of bacterial fungal viral andmycobacterial origin Several studies have been carried outin the past validating its antimicrobial antimycobacterialand antiviral potential (summarized in the Table 9) Duskoet al [91] investigated the antibacterial effect of the aqueousextract of 12 medicinal plants of Apiaceae family includingF vulgare An aqueous extract of the aerial part of Fvulgare inhibited the growth of Agrobacterium radiobacterpv tumefaciensErwinia carotovoraPseudomonas fluorescensand Pseudomonas glycinea (Table 9) An aqueous extract ofseed sample inhibited the growth of Enterococcus faecalisStaphylococcus aureus Escherichia coli Klebsiella pneumo-nia Pseudomona aeruginosa Salmonella typhi Salmonellatyphimurium Shigella flexneri and Bacillus cereus with 13ndash22 22ndash24 14ndash24 20-21 21ndash24 11-12 14ndash18 17ndash18 and 24ndash26mm zone of inhibition respectively [3 4] Gulfraz et al[92] investigated the antibacterial effect of the essential oil aswell as ethanolic and methanolic fruit extracts of F vulgareagainst Bacillus cereus Bacillus megaterium Bacillus pumilus

Bacillus subtilis Escherichia coliKlebsiella pneumoniaMicro-coccus luteus Pseudomonas putida Pseudomonas syringaeand Candida albicans According to the results reported byGulfraz et al [92] essential oil of F vulage had significantantimicrobial activities against some of microorganisms ascompared to the methanolic and ethanolic extracts Thediameters of growth inhibition zone ranged from 14 to 31mm(including the diameter of the disc 6mm) with the highestinhibition zone values observed against Bacillus megaterium(31mm) and Bacillus subtilis (29mm) Roby et al [23]investigated antimicrobial effect of the methanol ethanoldiethyl ether and hexane extracts of seed of F vulgare againsttwo species of Gram negative bacteria (Escherichia coli andSalmonella typhi) two species of Gram positive bacteria(Bacillus cereus and Staphylococcus aureus) one species ofyeast (Candida albicans) and one species ofmold (Aspergillusflavus)Themethanolic extract showedmore effective antimi-crobial activity than the other extracts The results fromthe disc diffusion method followed by measurement ofminimum inhibitory concentration (MIC) indicated thatBacillus cereus and Aspergillus flavus were the most sensitivemicroorganisms tested showing the largest inhibition zonesand the lowest MIC values Least activity was exhibitedagainstEscherichia coli with the smallest inhibition zones andthe highest MIC value [23] Shrivastava and Bhargava [93]investigated the antibacterial effect of the crude chloroformand methanol extract of leaves and flowers of F vulgarealong with Raphanus sativus and Brassica nigrum againstEscherichia coli and Staphylococcus aureus Methanol extractof flower of F vulgare showed significant activity againstEscherichia coli whereas crude and chloroform extractsfailed to exhibit antimicrobial activity against Staphylococcusaureus (Table 9) Among different tested bacterial strains the

molds Aspergillus niger and Fusarium oxysporum Essen-tial oil of F vulgare showed significant antifungal activityagainst the food spoilage fungi Aspergillus niger and Fusar-ium oxysporum and may have important applications asfood additives The MIC values of F vulgare essential oilwere 250120583gmL for Fusarium oxysporum and 750 120583gmLfor Aspergillus niger [94] The oils extracted from F vulgareexhibit varying levels of antifungal effects on the experi-mental mycelial growth of Alternaria alternata Fusariumoxysporum and Rhizoctonia solani [95] Essential oil of Fvulgare showed appreciable antifungal activity against strainsof pathogenic fungi namely Aspergillus niger Fusariumsolani and Rhizopus solani [96] Dichloromethane extractsand essential oils from F vulgare showed antifungal activityagainst Candida albicans It could be a potential candidatefor a new antifungal agent for candidiasis and other fungal

diseases [97] In an in vitro study aqueous and alcoholicseed extracts of F vulgare exhibited inhibitory effect againstAlternaria alternata Mucor rouxii and Aspergillus flavus[98] Interestingly aqueous seed extract of F vulgare showedstrongest antifungal activity as compared to reference fungi-cidal agent that is griseofulvin [99]

All of the above mentioned studies were carried outon the crude extracts and it is difficult to pinpoint theactive antimicrobial metabolite A phenylpropanoid deriva-tive called dillapional characterized from F vulgare stem wasfound to be an antimicrobial constituent with MIC values of125 250 and 125 against Bacillus subtilis Aspergillus nigerand Cladosporium cladosporioides respectively A coumarinderivative scopoletin was also isolated as a marginallyantimicrobial agent [100] The characterization of sevendifferent types of oxygenatedmonoterpenes frommethylene

chloride crude extract of F vulgare [101] suggested thatthe crude extract containing monoterpenes could be a newmedicinal resource for antibacterial agents

A total of 78 compounds were identified from theactive antimycobacterial fraction of F vulgare with thehelp of gas chromatography-mass spectra (GC-MS) Outof these twenty compounds were tested against one sensi-tive and three MDR strains of Mycobacterium tuberculosisusing the Alamar Blue microassay Compounds that showedsome degree of antimycobacterial activity against all strainstested were the following linoleic acid (MIC 100 120583gmL)oleic acid (MIC 100 120583gmL) 13-benzenediol (MIC 100ndash200120583gmL) undecanal (MIC 50ndash200120583gmL) and 24-undecadienal (MIC 25ndash50120583gmL) 24-Undecadienal wasthe most active compound against multidrug resistant Mtuberculosis speciesThus the dietary intake of F vulgaremaylower the risk ofM tuberculosis infection [63]

Orhan et al [5] studied the antiviral activity of theessential oil of fruit sample of F vulgare along with 12other Turkish medicinal plants against the DNA virusHerpessimplex type-1 (HSV-1) and the RNA virus parainfluenzatype-3 (PI-3) Most of the oils and compounds displayedstrong antiviral effects against HSV-1 ranging between 08and 0025 120583gmL However the samples tested were lesseffective against PI-3 with results ranging between 16 and02 120583gmL Only the essential oils of Anethum graveolensFoeniculum vulgare (fully mature) Mentha piperita Menthaspicata Ocimum minutiflorum Ocimum vulgaris and Sat-ureja cuneifolia inhibited this virus significantly

All these literature findings validated the traditional usesof Foeniculum vulgare in infectious disorders like abdomi-nal pains antiemetic arthritis conjunctivitis constipationdepurative diarrhea dieresis fever flatulence gastralgia gas-tritis insomnia irritable colon mouth ulcer stomachacherespiratory disorders skin diseases and so forth There isalways a need for new antimicrobial agents due to rapiddevelopment of resistance Bioactive metabolites of F vulgaremay be a potential source for new antimicrobial agents

42 Anti-Inflammatory Activity Oral administration ofmethanol extract of F vulgare fruit to rat and mice exhibitedinhibitory effects against acute and subacute inflammatorydiseases The anti-inflammatory activity of methanol extractwas evaluated by using three screening protocols namelycarrageenan-induced paw edema arachidonic acid-inducedear edema and formaldehyde-induced arthritis Theseare widely used for testing nonsteroidal anti-inflammatorydrugs For acute inflammationmethanol extract (200mgkg)exhibits significant inhibition of paw edema (69) inducedby carrageenan injection as compared to the control groupof animals Methanol extract of F vulgare also inhibitsear-edema (70) induced by arachidonic acid in mice Thelevel of serum transaminase aspartate aminotransferase(AST) and alanine aminotransferase (ALT) significantlyincreases in the presence of methanolic extract of F vulgareon inflammation induced by formaldehyde as comparedto control group The assessment of the level of AST and

ALT provides a good and simple tool to measure the anti-inflammatory activity of the target compounds [102] Theseoverall results seem to suggest that F vulgare FME mayact on both the cyclooxygenase and lipoxygenase pathways[79]

43 Antiallergic Activity Methanolic extract of F vulgarefruit showed significant inhibitory effect on DNFB- (24-dinitrofluorobenzene-) induced delayed type hypersensitiv-ity after oral administration of 200mgkg once a day for7 days The inhibitory effect on immunologically inducedswelling suggests the possible immunosuppressive propertiesof F vulgare [79]

44 Hepatoprotective Activity Essential oil of F vulgareseeds revealed a potent hepatoprotective effect against acutehepatotoxicity produced by carbon tetrachloride in ratsOral administration of F vulgare essential oil decreases thelevels of serum aspartate aminotransferase (AST) alanineaminotransferase (ALT) alkaline phosphatase (ALP) andbilirubin as compared to the control group Ozbek et alsuggest that the constituents (d-limonene and 120573-myrcene) ofessential oil may have played a key role in the protection ofliver from CCl

4toxicity [9]

45 Anxiolytic Activity Anxiety is the unpleasant feeling offear and concern When anxiety becomes excessive it maybe considered as an anxiety disorder Anxiolytic fennel isa drug used for the treatment of anxiety and its relatedpsychological and physical symptoms Naga Kishore et al[89] investigated the anxiolytic activity of ethanolic extract ofF vulgare fruit with the help of elevated plus maze rota rodopen field test and whole board models The 100 to 200mgdose of extract per kg of body weight of animal revealedsignificant activity when compared to reference anxiolyticdrug called diazepam (1mgkg) Thus fennel extract maypossess anxiolytic activity supporting its traditional claimabout anxiolytic activity reported in 19th edition of Pharma-cology and Pharmacotherapeutics by Sathodkar Bhandarkarand Rege

46 Antistress Activity Drug and food of natural originplay a significant role in public healthcare systems and arebeing investigated as remedies for a number of stress-relateddisorders [103]Thewhole plant extract of F vulgare exhibitednotable antistress effect against stress induced by forcefulswimming of test animals The key parameters that isurinary levels of vanillyl mandelic acid (VMA) and ascorbicacid in rats were used to evaluate antistress activity Theplant extract (50 100 and 200mgkg body weight) showeda significant improvement in urinary levels of VMA (119875 lt0001) and ascorbic acid excretion levels (119875 lt 0001) in testanimals when compared to the normal basal levels in controlgroup of animalsThus the extract of entire plant of F vulgareacts as an antistress agent [13]

47 Memory-Enhancing Property There are a number ofplants whose consumption is believed to enhance memory

22 BioMed Research International

and intelligence These were usually given to children as partof their food F vulgaris an ayurvedic rasayana (mixture)possessing multiple neuropharmacological activities Theantidepressant activity of fennel has been well documentedin ethnomedicine The whole plants extract (50 100 and200mgkg) of F vulgare exhibited memory-enhancing effectagainst scopolamine-induced amnesic rats This experimentwas evaluated by conditioned avoidance response (CAR)technique The CAR of rats administered with the extractincreased gradually to 95 over 7 to 12 days The acquisition(time to achieve 95 CAR) for rats administered with theextract was dose- and time-dependent compared to controlgroup which took 12 days for acquisition The percentavoidance was always higher in the extract-treated groupsas compared to control group Animals receiving 200mgkgbody weight of the extract took ten days while groups treatedwith 100 and 50mgkg doses of the extract required elevenand twelve days respectively to reach the point of acquisitionAdministration of scopolamine produced amnesia as seenfrom reduction in the observed CAR Amnesia was greaterin the control group than in extract-treated groups How-ever continued treatment with F vulgare produced betterretention and recovery in a dose-dependent manner thanthe vehicle-treated animals Recovery from scopolamine-induced amnesia in the extract-treated groups took 3ndash5 dayswhen compared to normal (control) group which took over6 days This overall progress suggests that F vulgare extractpossesses memory-enhancing property [13]

48 Nootropic Activity Alzheimerrsquos disease is a neurode-generative disorder associated with a decline in cognitiveabilities Dementia is one of the age-related mental problemsand a characteristic symptom of Alzheimerrsquos disease Thereis some evidence in favor of use of F vulgare for the treat-ment of cognitive disorders like dementia and Alzheimerrsquosdisease Methanol extract of the whole plant of F vul-gare administered for eight successive days ameliorated theamnesic effect of scopolamine and aging-induced memorydeficits inmiceThis extract increased step-down latency andacetylcholinesterase inhibition in mice significantly Thus Fvulgaremay be employed in treatment of cognitive disorderssuch as dementia and Alzheimerrsquos disease as a nootropic andanticholinesterase agent [80]

49 Antihirsutism Activity Idiopathic hirsutism is definedas the occurrence of excessive male pattern hair growth inwomen who have a normal ovulatory menstrual cycle andnormal levels of serum androgens It may be a disorder ofperipheral androgen metabolism Traditionally Foeniculumvulgare has been used as an estrogenic agent It has beenreputed to increase milk secretion promote menstruationfacilitate birth and increase libido On considering aboveaspect Javidnia and his research team evaluated the antihir-sutism activity of ethanolic extract of F vulgare seed againstidiopathic hirsutism by preparing cream containing 1 and 2of fennel extract The efficacy of treatment with the creamcontaining 2 fennel is better than the cream containing 1fennel and these two were more potent than placebo (control

group) The mean values of hair diameter reduction were78 183 and minus05 for patients receiving the creamscontaining 1 2 and 0 (placebo) respectively [78]

410 Estrogenic Properties Since the discovery of the estrusinducing effects of some plant products in 1926 consider-able effort has been devoted towards the characterizationof phytoestrogens including flavonoids isoflavonoids chal-cones coumestans stilbenes lignans saponins and essentialoils [16] F vulgare has estrogen-like activity In male ratstotal concentration of protein was found to be significantlydecreased in testes and in vasa deferentia whereas increasedin seminal vesicles and in prostate gland On the otherhand simultaneous decrease in the activities of acid andalkaline phosphatase in all these regions (except that alka-line phosphatase was unchanged in vasa) due to the oraladministration of acetone extract of F vulgare fruit wasobserved In female rats oral administration of the extract for10 days led to vaginal cornification and oestrus cycle [8] Totalconcentration of nucleic acids and protein as well as the organweights increased in both the tissues namely mammaryglands and oviducts due to the oral administration of acetoneextract (50 150 and 250120583g100 g body wt) of F vulgare seeds[104] Fennel oil was reported to exhibit estrogenic activitypromote menstruation and alleviate the symptoms of femaleclimacteric and increase libido [71] Administration of fenneloil (25 and 50 120583gmL final concentration in the organ bath)failed to exhibit any remarkable effect in uterine contrac-tion While 10 20 and 40 120583gml concentration of fennel oilrevealed significant inhibitory effect against prostaglandinE2 Fennel oil significantly reduces the frequency of uterinecontraction induced by prostaglandin E2 Thus the extractsof F vulgare have strong estrogenic activity [76]

411 Galactogenic Activity Foeniculum vulgare has been usedformillennia to increasemilk secretion [105]Thus F vulgarebelongs to galactagogue substance Structural similarity ofits main constituent anethole to dopamine seems to beresponsible for galactogenic activityDopamine acts to inhibitthe secretion of the milk-producing hormone prolactinAnethole might influence milk secretion by competing withdopamine at the appropriate receptor sites thereby inhibitingthe antisecretory action of dopamine on prolactin [71] It wasreported that anol (demethylated anethole) causes growthof the lobule-alveolar system in the mammary glands ofimmature female rabbits and induces menstruation in miceand other experimental animals Anol also gave positiveresults in the Jadassohn nipple test a test which involvesthe measurement of changes induced in the nipples ofguinea pigs subjected to the cutaneous application of sexhormones However further research suggests that the actualpharmacologically active agents responsible for galactogenicactivity are polymers of anethole such as dianethole andphotoanethole rather than anol or anethole itself [20 76]

412 Expectorant Activity F vulgare seeds stimulate theciliary motility of the respiratory apparatus and enhance the

BioMed Research International 23

external transport of extraneous corpuscles This action sug-gests a use for fennel in treating bronchial and bronchopul-monary afflictions and in particularly polluted environments[106] The volatile oil of F vulgare stimulates the contractionof the smooth muscles of the trachea an action that couldfacilitate the expectoration of mucus bacteria and othercorpuscles extraneous to the respiratory tracts [74]

413 Anticolitic Activity Essential oil of fennel regulates themotility of smooth muscles of the intestine while at thesame time reducing intestinal gas Alone or combined withother plant medicinals Foeniculum vulgare is indicated in thetreatment of spastic gastrointestinal disturbances in someforms of chronic colitis (which resist other treatments) indyspepsias from gastrointestinal atony in dyspepsias withthe sensation of heaviness in the stomach and so forthTheaddition of fennel to preparations containing anthraquinoniccomponents reduces the occurrence of abdominal pain oftenassociated with this type of laxative [73]

414 Antinociceptive Activity Antinociceptive means anysubstance that inhibits nociception which is a physiologicalprocess underlying the sensation of pain Briefly it reducesthe sensitivity to painful stimuli The various extracts ofaerial part of F vulgare namely hexane methylene chlorideethyl acetate and methanolic extract showed remarkableantinociceptive activity against acetic acid induced writhingin mice [68] The methanolic extract of the aerial parts ofF vulgare exhibited the highest antinociceptive activity at adose level of 2000mgkg while the activity exhibited by theethyl acetate extract was at dose level 800mgkgOn the otherhand n-hexane extract (700mgkg) and methylene chlorideextract (500mgkg) exhibited similar antinociceptive activi-ties being less than peripheral antinociceptive reference drug(acetyl salicylic acid) [68]

415 Diuretic Activity A diuretic is any substance thatpromotes the production of urine Briefly it is an agentthat promotes diuresis Diuretics work by promoting theexpulsion of urine (measured as the urine volume [UV]excreted) and urinary sodium (UNa) from the body and thishelps reduce the volume of blood circulating through thecardiovascular system Caceres et al [107] performed a studyin conscious animals and administered a powdered extractof the whole plant (F vulgare) which had no effect on UVor UNa The ethanolic extract of F vulgare fruit revealedexcellent diuretic activity and proves the earlier folk claimof F vulgare which was reported in the United State ofAmerica (Table 5) The fruit extract showed statistically ahighly significant diuretic effect F vulgare induced diuresis(500mgkg dose)was comparable to that of reference diureticagent urea (960mgkg dose) in mice with a urine outputthat was almost double that of the control group Thediuresis was not associated with changes in sodium andorpotassium excretion [108] In another part of the study theauthors showed that Foeniculum vulgare had little effect onthe noradrenalin contractile responses of aortic rings thus

suggesting that it worked mainly as a diuretic and natriureticwith little effect on arterial vascular tone [77]

416 Cardiovascular Activity An aqueous extract of F vul-gare leaves possesses potential cardiovascular action Thiseffect was investigated using pentobarbital-anaesthetisedmale albino Sprague-Dawley rats [75] An intravenousadministration of the lyophilized boiled water extract ofleaves produced a significant dose-related reduction in arte-rial blood pressure without affecting the heart rate or respi-ratory rate On the other hand the nonboiled aqueous extractshowed very little hypotensive activityThe hypotensive effectof the boiling water extract appeared not to be mediated viaadrenergicmuscarinic ganglionic or serotonergic receptorshowever histamine antagonists inhibited the hypotensiveeffect in a dose-related manner [75]

417 Oculohypotensive Activity The aqueous seed extract ofF vulgare demonstrated significant oculohypotensive activityusing water loading and steroid induced glaucoma modelThis extract exhibited 1749 2116 and 2203 reduction ofintraocular pressure in normotensive rabbits at 03 06and 12 (wv) concentrations respectively A maximummean difference of 3120 was observed between vehiclestreated and extracts treated eyes in water loading experi-mental animal model while a maximum mean intraocularpressure lowering of 3129 was observed in steroid inducedmodel of glaucoma Thus the aqueous extract of F vulgarerevealed oculohypotensive activity which was found to be asgood as that of reference standard antiglaucoma drugs calledtimolol [84]

418 Antithrombotic Activity Tognolini et al [55] providedevidence of potent inhibitory activity of essential oil of F vul-gare against platelet aggregation induced byADP arachidonicacid and collagen in guinea pig plasma Similar findingswere reported by Yoshioka and Tamada [109] for aggregationof rabbit platelets by an aromatic factor of fennel oil Theessential oil and anethole (a constituent of oil) of F vulgaretested in vitro in rat aorta with or without endotheliumdisplayed comparable NO-independent vasorelaxant activityat antiplatelet concentrations It supports the safety of Fvulgare that is free from cytotoxic effects Anethole and Fvulgare did not cause cytotoxicity when incubated for 30minupto 300 120583gmL in platelet viability test This concentrationwas largely compatible with those adopted in the functionalin vitro tests In vivo both F vulgare essential oil andanethole orally administered in a subacute treatment to mice(30mgkgday for 5 days) showed significant antithrom-botic activity preventing the paralysis induced by collagen-epinephrine intravenous injection (70 and 83 protectionresp)Thus essential oil and its main component anethole ofF vulgare showed a safe antithrombotic activity in guinea pigplasma that seems due to their broad spectrum antiplateletactivity clot destabilizing effect and vasorelaxant action [55]

419 Antimutagenic Effect Essential oil of F vulgare revealednoteworthy protective effects against genotoxicity in mice

24 BioMed Research International

induced by cyclophosphamide Genotoxicity and cytotoxicitywere assessed by using mice bone marrow chromosomalaberration micronucleus and sperm abnormality assaysrespectively Oral administration of essential oil (1 and2mLkg) significantly inhibited the frequencies of aberrantmetaphases chromosomal aberrations micronuclei forma-tion and cytotoxicity in mouse bone marrow cells inducedby cyclophosphamide and also produced a significant reduc-tion of abnormal sperm and antagonized the reduction ofcyclophosphamide induced superoxide dismutase catalaseand glutathione activities and inhibited increased malondi-aldehyde content in the liver Additionally F vulgare inhibitsthe oxidative stress induced by cyclophosphamide [90]

420 Gastrointestinal Effect Theaqueous extract of F vulgareshowed remarkable antiulcerogenic effect against ethanol-induced gastric lesions in rats It was found that pretreatmentwith aqueous extract significantly reduced ethanol-inducedgastric damageThis effect of aqueous extract was highest andstatistically significant in 300mgkg group comparedwith thecontrol (119875 lt 0001) group of animal Additionally aqueousextract of F vulgare significantly reduced the whole bloodmalondialdehyde levels while significantly increased nitritenitrate ascorbic acid retinol and beta-carotene levels Thusaqueous extract of F vulgare fruit had clearly a protectiveeffect against ethanol-induced gastric mucosal lesion in rats[81]

421 Chemomodulatory Action The chemopreventive effectof different doses of test diet of Foeniculum vulgare seeds wasexamined against 712-dimethylbenz(a)anthracene- (DMBA-) induced skin papillomagenesis and benzo(a)pyrene-[B(a)P-] induced forestomach papillomagenesis at the peri-initiational level in Swiss albino mice Fennel seeds exhibita significant reduction in the skin and the fore-stomachtumor incidence and tumor multiplicity as compared tothe control group Further biochemical assays showeda significant increase in the contentactivities of phase Ienzymes especially in the case of 6 test diet A concomitantincrease in the activities of the phase II enzymes wasobserved with all the doses of test diet under study Asignificant enhancement in the activities of antioxidantenzymes was observed especially at 4 and 6 test diets offennel These findings were indicative of chemopreventivepotential of fennel against carcinogenesis This is the firstreport showing chemopreventive potential of seeds of fennelagainst carcinogenesis [85]

422 Cytoprotection and Antitumor Activity Anethole is theprincipal active component of fennel seeds which has exhib-ited anticancer activity Al-Harbi et al studied the antitumoractivity of anethole against Ehrlich ascites carcinoma inducedin a tumor model in Swiss albino mice The study revealedthat anethole increased survival time reduced tumor weightand reduced the volume and body weight of the Ehrlichascites tumour-bearing mice It also produced a significantcytotoxic effect in the Ehrlich ascites tumour cells in the pawreduced the levels of nucleic acids and malondialdehyde and

increased glutathione concentrations [110] In vitro cytopro-tection activity of methanolic extract of Foeniculum vulgarewas evaluated against normal human blood lymphocytes bymicronucleus assay and antitumor activity against B16F10melanoma cell line by Trypan blue exclusion assay for cellviability Lymphocyte culture treated with 70 methanolicextract of Foeniculum vulgare showed very less percentage ofmicronucleus that is 0006 as compared to standard drugdoxorubicin which showed 0018 micronucleus On theother hand 70methanolic extract of Foeniculum vulgare haspotent antitumor activity at the concentration of 200120583gmLThe results suggest that the Foeniculum vulgare could beconsidered as a natural resource of antitumor agents as wellas cytoprotective to normal cells [11]

423 Cytotoxicity Kaileh and his coworker investigated thecytotoxic effect of organic extracts of 24 selected Palestinianmedicinal plant species The plant selection was based onexisting ethnobotanic information and interviews with localhealers The extracts of the plants under investigation weretested for their potential antitumor (cytotoxic) effect on themurine fibrosarcoma L929sA cells and on the human breastcancer cells MDA-MB231 and MCF7 The extract from Fvulgare presented an IC (50) value at 24 h of 700 plusmn 28 and500plusmn17 120583gmL on L929sA andMCF7 cells respectivelyThenuclear transcription factor NFkappaB or NF120581B regulatesthe expression of various genes They further investigatedthe effect of nine promising plant extracts withheld fromthe first cell viability screening on NF120581B activation Thedichloromethane and methanol (1 1) extract of aerial part ofF vulgare revealed immunomodulatory NF120581B activities [82]Also Berrington and Lall investigated the in vitro cytotoxicityof acetone extracts of F vulgare and other eight medicinalplants against a noncancerous African green monkey kidney(Vero) cell line and an adenocarcinoma cervical cancer(HeLa) cell line [87]

424 Antipyretic Activity F vulgare extract showedantipyretic activity against hyperpyrexia in mice It wasinduced by SC administration of 2mL100 g of a 20aqueous suspension of brewerrsquos yeast As an antipyreticagent ethanolic extract of F vulgare fruit showed a moderateantipyretic activity that was statistically significant after 30and 90min (119875 lt 001) [108]

425 Hypolipidemic Activity The aqueous extract of F vul-gare revealed notable hypolipidemic and antiatherogenicactivity against Triton WR-1339 induced hyperlipidemiain mice Aqueous extract causes significant reduction ofplasma lipid levels that is cholesterol triglycerides LDL-cholesterol and apolipoprotein-B decreased by 40 2361 and 61 respectively and increase in HDL-cholesteroland apolipoprotein A1 by 85 and 58 respectively [88]

426 Hypoglycemic Activity The essential oil of F vulgareexhibits potential hypoglycemic and antioxidant activityagainst streptozotocin induced diabetes in rats Essentialoil (30mgkg body weight) of F vulgare works in the

BioMed Research International 25

correction of hyperglycemia from 1625 plusmn 319mgdL to8197 plusmn 197mgdL with 119875 lt 005 and the activity of serumglutathione peroxidase from 5972 plusmn 278Ug Hb to 9960 plusmn638Ug Hb with 119875 lt 005 Also essential oil of fennelimproves the pathological changes noticed in their kidneyand pancreas as compared with the control group of animalThis can prove its effect as antidiabetic in folk Medicine Thismakes the possibility of its inclusion in antidiabetic drugindustry [12]

427 Antispasmodic Activity The antispasmodic activity of25 and 100mLL of alcoholic extract of Foeniculum vulgarealong with other Germanic medicinal plants namelyMelissaofficinalis Rosmarinus officinalisMentha piperitaMatricariachamomilla Carum carvi and Citrus aurantium were testedemploying the guinea pig ileum and using acetylcholine andhistamine as spasmogens An alcoholic extract of the fruits ofFoeniculum vulgare possesses antispasmodic activity whichinhibits the acetylcholine and histamine-induced guineapig ileal contractions in vitro An essential oil which isobtained from the fruits of Foeniculum vulgare 25 120583gmL and10 120583gmL respectively inhibited oxytocin and prostaglandin[72]

428 Apoptotic Activity The apoptotic activities of ethanolextracts from fruits of seven species of Apiaceae familynamely Eryngium planum Archangelica officinalis Pasti-naca sativa Heracleum sibiricum Carum carvi Foenicu-lum vulgare and Levisticum officinale against ML-1mdashhumanacute myeloblastic leukaemia J-4501mdashhuman acute Tcell leukaemia EOLmdashhuman eosinophilic leukaemia HL-60mdashhuman Caucasian promyelocytic leukaemia 1301mdashhuman T cell leukaemia lymphoblast C-8166mdashhuman Tcell leukaemia U-266B1mdashhuman myeloma WICLmdashhumanCaucasian normal B cell and H-9mdashhuman T cell wereinvestigated with the help of Trypan blue assay and AnnexinV fluos assay [86] The ethanol extract from fruit F vulgareshowed the highest mortality in Trypan blue test for J45cell linemdash4 of viable cells and for C8166 cell linemdash100of mortality However the cells of other lines showed thehighest viability HL60mdash60 EOLmdash48 and MLmdash1ndash42The normal cell line H9 and WICL showed 35 and 25of viable cells respectively C8166 cell line and J-45 cell lineshowed the highest level of the apoptotic cells detected byAnnexin V methodmdash100 and 93 respectively Howeverthe cells of two lines HL60 and EOL-1 showed the lowerlevels of apoptotic cellsmdash52 and 60 respectively Highpercentage of apoptotic cells was observed inH9 andWICLmdash76 and 93 respectively [86]

429 Human Liver Cytochrome P450 3A4 Inhibitory ActivityThirteen compounds isolated from the methanolic extract offennel have been found to possess human liver cytochromeP450 3A4 inhibitory activity Among these compounds 5-methoxypsoralen (5-MoP) showed the strongest inhibitionwith an IC50 value of 183120583m and with a mixed type ofinhibition [83]

430 Antiaging Effects Rasul and his coworker developeda base and formulation containing 4 concentrated seedextract of F vulgare This formulation shows notable antiag-ing effect with supporting experimental data related to skinmoisture and transepidermal water loss (TEWL) The basewas insignificant while the formulation showed significanteffects on skin moisture and TEWL The texture parameterenergy showed a significant increase proving that the formu-lation possesses potential antiaging effects [50]

431 Bronchodilatory Effect Ethanol extract and essential oilfrom F vulgare exhibited bronchodilatory activity on con-tracted tracheal chains of guinea pig The potassium channelopening effect of fennel may contribute on its relaxant effecton guinea pig tracheal chains [111] Moreover anethole bearsa striking resemblance to the catecholamines epinephrinenorepinephrine and dopamine This structural similarityappears to be responsible for the various sympathomimeticactivities of F vulgare such as bronchodilatory effect [71]

432 Antioxidant Activities Naturally occurring antioxi-dants can be used to protect human beings from oxidativestress damage [112] Fennel was known as excellent source ofnatural antioxidants and contributed to the daily antioxidantdiet [113]Wild fennel was found to exhibit a free radical scav-enging activity with higher content phenolic and flavonoidthan medicinal and edible fennel and the aerial parts ofthe Italian fennel populations showed the highest DPPHscavenging activity [65] Phenolic compounds of fennelincluding caffeoylquinic acid rosmarinic acid eriodictyol-7-orutinoside quercetin-3-O-galactoside and kaempferol-3-O-glucoside showed antioxidant activities [67] The volatileoil showed strong antioxidant activity in comparison withbutyrated hydroxyanisole and butylated hydroxytolueneEthanol and water extracts of fennel showed less antioxidantactivity compared with essential oil [114]

5 Environmental Application

Foeniculum vulgare that is fennel not only exhibited phar-macological activities but also revealed a few environmentalactivities These activities play a key role in the managementof nematode insect mosquitoes and some harmful larvae ofmalaria producing vector Thus the extracts of F vulgare andisolated biologically active compounds have been evaluatedfor their insecticidal repellent acaricidal larvicidal andnematicidal activity [115ndash119] A brief review on the differenttype of ecofriendly environmental activities as reported onthis plant is summarized below

51 Insecticidal Activities The fruit derived phytoconstitu-ents of F vulgare exhibited prominent insecticidal activi-ties against Sitophilus oryzae Callosobruchus chinensis andLasioderma serricorne This activity was examined usingdirect contact application and fumigation methods Thebiologically active constituents that is phenylpropenes (E)-anethole and estragole and the monoterpene (+)-fenchonewere characterized from Foeniculum fruit By using a filter

26 BioMed Research International

paper diffusion test estragole (0168mg cmminus2) caused 91mortality to S oryzae within 1 day after treatment whereas(+)-fenchone and (E)-anethole gave over 90 mortality at 2and 4 day after treatment respectively

After 2 days of treatment all test compounds (0021mg cmminus2 concentration) revealed potent insecticidal activityagainst C chinensis Whereas after 1 day of treatment (E)-anethole (0105mg cmminus2) gave 100mortality of L serricornewhereas 90 and 60 mortality at 4 day after treatment wasachieved with estragole and (+)-fenchone respectively In afumigation test the compounds were much more effectiveagainst adults of S oryzae C chinensis and L serricorne inclosed cups than in open ones indicating that the insecticidalactivity of test compounds was largely attributable to fumi-gant action As naturally occurring insect-control agents theF vulgare fruit-derived materials described could be usefulfor managing field populations of S oryzae C chinensis andL serricorne [116]

52 Acaricidal Activity Fennel oil shows significant acaricid-al activity againstDermatophagoides farinae andDermatoph-agoides pteronyssinus (+)-fenchone and p-anisaldehyde aremajor constituents of fruit oil of F vulgare P-anisaldehydewas the most toxic compound against D farinae and is muchmore effective compared with benzyl benzoate thymol andestragol [118]

53 Repellent Activity The methanolic extract of fruits ofF vulgare was spectroscopically characterized for the pres-ence of biologically active constituents called (+)-fenchoneand (E)-9-octadecenoic acid The repellent activity of theseconstituents was tested against hungry Aedes aegypti femaleswith the help of skin and patch tests and compared withthat of the commercial repellent agent called NN-diethyl-m-toluamide (DEET) and (Z)-9-octadecenoic acid In askin test with female mosquitoes (+)-fenchone and (Z)-9-octadecenoic acid (04mgcm2) exhibitedmoderate repellentactivity at 30min after treatment whereas DEET providedgt1 h of protection against adult mosquitoes at (02mgcm2)Thus (+)-Fenchone and (E)-9-octadecenoic acid are poten-tial mosquito repellent agents or lead compounds [117]

54 Larvicidal Activity Plant extracts and oils may act asalternatives to conventional pesticides for malaria vectorcontrol By considering this aspect Sedaghat et al [119] inves-tigated the larvicidal activity of essential oils of three plantsof Apiaceae family against malaria vector called Anophe-les stephensi The larvicidal activity was evaluated againstlaboratory-reared larvae by standard method of WHO TheF vulgare oil was the most effective against A stephensiwith LC(50) and LC(90) values of 2010 and 4451 ppmrespectively [119] Additionally the essential oil extracts fromleaves flowers and roots of F vulgare exhibit noticeablelarvicidal activity against fourth-instar larvae of themosquitoCulex pipiens molestus Terpineol and 18-cineole content of Fvulgare are the most effective phytoconstituent against Culexpipiens molestus bites offering complete protection for 16 and2 h respectively [120] Recently Zoubiri et al [57] reported

the larvicidal activity of essential oil of fennel seed againstCulex pipiensmosquitoThus F vulgare can serve as a naturallarvicidal agent

55 Nematicidal Activity Oka et al investigated the in vitronematicidal activity of essential oils extracted from 27 spicesand aromatic plants in pot experiments Twelve of thetwenty-seven essential oils immobilized more than 80 ofjuveniles of the root-knot nematodeMeloidogyne javanica ata concentration of 1000 120583Lliter At this concentration mostof these oils also inhibited nematode hatching Essential oilsof Carum carvi Foeniculum vulgare Mentha rotundifoliaand Mentha spicata showed the highest nematicidal activityamong the in vitro tested oils In 3-liter pot experimentsnematicidal activity of the essential oils and their componentswas confirmed at 200 and 150mgkg respectivelyThe resultssuggest that the essential oils and theirmain componentsmayserve as nematicides [115]

6 Toxicity

The long history of ethnomedicinal application with noreports of any serious side effects suggests that F vulgarecould be considered as safe Inmost toxicity experiments car-ried out on F vulgare no sign of toxicity was observed Shahand his coworker in 1991 investigated the detailed toxicityaccount of ethanolic extract of fennel fruit in experimentalmice with respect to acute and 90 days longer term toxicity[121] In experimentation Shah and his coworker observedthe general symptoms of toxicity and mortality for only 24 hin acute toxicity Whereas in another part of toxicity theystudied the effect of fennel extract on mice with 90 dayslong term treatment Acute toxicity of ethanolic extract of Fvulgarewas assessed in 35mice by using three concentrationsnamely 05 1 and 3 gkg body weight In this investigation Fvulgare exhibited no signs of toxicity and no mortality wasobserved upto the dose level 3 gkg body weight In case oflonger term toxicity ethanolic extract of F vulgare (100mgkgbody weightday) was given in drinking water of animals(30 male and 30 female mice) All external morphologicalhaematological and spermatogenic changes in addition tobody and vital organ weights were recorded The extractcaused no significant chronic mortality as compared tocontrols during this investigation The treated male micegained significant weight during chronic treatment while aloss or no significant change in weight was noticed in thefemale mice treated with the same extract The extracts didnot show spermatotoxic effects Thus Shah and his coworkerconcluded that fennel extract is safe based on both acuteandor long term toxicity studies [121] Additionally the plantextract in doses of 05 1 and 3 gkg (orally) did not causeany deaths These doses do not show any type of toxicityagainst several parameters tested namely locomotor activitybizarre reactions sensitivity to sound social interaction tailposture aggressive behaviour ataxia paralysis convulsionstremors prostration exophthalmos pupil size defecationsalivation urination pattern of respiration nasal dischargecyanosis and piloerection Exceptionally only the 3 gkg dose

BioMed Research International 27

showed signs of reduced locomotor activity and piloerec-tion Otherwise all other parameters were negative [108]In another experiment of acute toxicity different solventextracts namely n-hexane methylene chloride ethyl acetateand methanol extracts of F vulgare upto 55 gkg concentra-tion did not revealed any kind of toxicity in mice LD50being 675 110 692 and 15 gkg for n-hexane methylenechloride ethyl acetate and methanol extracts respectively[68] The plant extract of F vulgare was administered orallyat a dose of 100 200 400 600 800 1000 and 2000mgkgof body weight of mice Each group of animals was undervisual observation for 10 days for the external behavior ofneurological toxicity created by plant extract Even the micereceiving highest dose of F vulgare extract did not show anymortality or toxicity demonstrating the safety profile of theplant extract [89]

The acute oral 50 LD50 for anethole in rats was foundto be 2090mgkg Repeated doses of one-third the LD50 ofanethole (695mgkg) given to rat caused mild liver lesionsIt would therefore appear that in normal therapeutic dosagesanethole would have minimal hepatotoxicity When anetholewas fed to rats daily for one year as 025 of the dietno hepatic damage was seen [122] The acute oral LD50 ofessential oil in rats is 1326mgkg [76] The use of F vulgareessential oil as a remedy for control of primary dysmenorrheaincreases concern about its potential teratogenicity due toits estrogen like activity Evaluation of teratogenicity ofessential oil using limb bud mesenchymal cells showed thatthe essential oil may have toxic effect on fetal cells butthere was no evidence of teratogenicity upto concentrationof 93mgmL of culture medium [123] The overall toxicitystudies carried out on F vulgare accounts for its safety at therecommended therapeutic doses

7 Conclusions

The available scientific research on Foeniculum vulgarehas shown that it is an important medicinal plant used ina wide range of ethnomedical treatments especially forabdominal pains antiemetic aperitif arthritis cancer colicin children conjunctivitis constipation depurative diarrheadieresis emmenagogue fever flatulence gastralgia gastritisinsomnia irritable colon kidney ailments as a laxativeleucorrhoea liver pain mouth ulcer and stomachache Thisplant has been in use for a long period of time withoutany documented serious adverse effects Studies carriedout in the past and present indicate that fennel possessesdiverse health benefits and are an important constituentof food Studies have shown that various extracts offennel possess a range of pharmacological actions such asantiaging antiallergic anticolitic antihirsutism anti-inflam-matory antimicrobial and antiviral antimutagenic antino-ciceptive antipyretic antispasmodic antistress antithromb-otic anxiolytic apoptotic cardiovascular chemomodulatoryaction cytoprotection and antitumor cytotoxicity diureticestrogenic properties expectorant galactogenic gastrointes-tinal effect hepatoprotective human liver cytochrome P4503A4 inhibitory hypoglycemic hypolipidemic memory-en-hancing property nootropic and oculohypotensive activity

supporting its traditional use However the most prominentand the well studied effects are the antimicrobial andantioxidant effects of essential oil of fennel in differentexperimental models The observed health benefits may becredited to the presence of the various phytochemicals likevolatile compounds flavonoids phenolic compounds fattyacids and amino acids

Fennel also contains mineral and trace elements likealuminum barium calcium cadmium cobalt chromiumcopper ironmagnesiummanganese nickel lead strontiumand zinc [124] fat soluble vitamins such as vitamins A Eand K water soluble vitamins like ascorbic acid thiamineriboflavin niacin and pyridoxine essential amino acidslike leucine isoleucine phenylalanine and tryptophane maycontribute to the myriad health beneficial effects at least inpart

Most of the pharmacological studies were conductedusing uncharacterized crude extracts of fennel It is difficultto reproduce the results of these studies and pinpoint thebioactive compounds Hence there is a need for chemi-cal standardization and bioactivity-guided identification ofbioactive compounds Among several classes of chemicalconstituents identified in fennel volatile components of fen-nel essential oil and phenolic compounds are assumed to bethe main bioactive compounds responsible for the majorityof its pharmacological effects However the vast traditionaluse and proven pharmacological activities of fennel indicatethat an immense scope still exists for its chemical explorationFuture studies should be focused on validating the mecha-nism of action responsible for the various beneficial effectsand also on understanding which plant based compounds areresponsible for the reported effectsThe required informationwhen available will enhance our knowledge and appreciationfor the use of fennel in our daily diet Also the outcomeof such chemical studies may further expand its existingtherapeutic potential

Thus there are many areas of research related to thisplant that need to be further explored to fully recognize itsbeneficial effects for society Factors such as geographical andseasonal variation play an important role in the authentica-tion of the chemical constituents responsible for the activitywhich also can be an area of interest Thus it is incumbenton researchers to fill the huge gap of insufficient knowledgeand create awareness among pharmacologists as well as inves-tigators towards providing better medicinal value derivedfrom this plant This can be fulfilled only by generatinginterest among the research community through writing ofcritical appraisals (paper) and extending the interdisciplinaryresearch area to focused studies on Foeniculum vulgare

41 Antimicrobial and Antiviral Activities Foeniculum vul-gare has been used as an ethnic remedy for the cure ofnumerous infectious disorders of bacterial fungal viral andmycobacterial origin Several studies have been carried outin the past validating its antimicrobial antimycobacterialand antiviral potential (summarized in the Table 9) Duskoet al [91] investigated the antibacterial effect of the aqueousextract of 12 medicinal plants of Apiaceae family includingF vulgare An aqueous extract of the aerial part of Fvulgare inhibited the growth of Agrobacterium radiobacterpv tumefaciensErwinia carotovoraPseudomonas fluorescensand Pseudomonas glycinea (Table 9) An aqueous extract ofseed sample inhibited the growth of Enterococcus faecalisStaphylococcus aureus Escherichia coli Klebsiella pneumo-nia Pseudomona aeruginosa Salmonella typhi Salmonellatyphimurium Shigella flexneri and Bacillus cereus with 13ndash22 22ndash24 14ndash24 20-21 21ndash24 11-12 14ndash18 17ndash18 and 24ndash26mm zone of inhibition respectively [3 4] Gulfraz et al[92] investigated the antibacterial effect of the essential oil aswell as ethanolic and methanolic fruit extracts of F vulgareagainst Bacillus cereus Bacillus megaterium Bacillus pumilus

Bacillus subtilis Escherichia coliKlebsiella pneumoniaMicro-coccus luteus Pseudomonas putida Pseudomonas syringaeand Candida albicans According to the results reported byGulfraz et al [92] essential oil of F vulage had significantantimicrobial activities against some of microorganisms ascompared to the methanolic and ethanolic extracts Thediameters of growth inhibition zone ranged from 14 to 31mm(including the diameter of the disc 6mm) with the highestinhibition zone values observed against Bacillus megaterium(31mm) and Bacillus subtilis (29mm) Roby et al [23]investigated antimicrobial effect of the methanol ethanoldiethyl ether and hexane extracts of seed of F vulgare againsttwo species of Gram negative bacteria (Escherichia coli andSalmonella typhi) two species of Gram positive bacteria(Bacillus cereus and Staphylococcus aureus) one species ofyeast (Candida albicans) and one species ofmold (Aspergillusflavus)Themethanolic extract showedmore effective antimi-crobial activity than the other extracts The results fromthe disc diffusion method followed by measurement ofminimum inhibitory concentration (MIC) indicated thatBacillus cereus and Aspergillus flavus were the most sensitivemicroorganisms tested showing the largest inhibition zonesand the lowest MIC values Least activity was exhibitedagainstEscherichia coli with the smallest inhibition zones andthe highest MIC value [23] Shrivastava and Bhargava [93]investigated the antibacterial effect of the crude chloroformand methanol extract of leaves and flowers of F vulgarealong with Raphanus sativus and Brassica nigrum againstEscherichia coli and Staphylococcus aureus Methanol extractof flower of F vulgare showed significant activity againstEscherichia coli whereas crude and chloroform extractsfailed to exhibit antimicrobial activity against Staphylococcusaureus (Table 9) Among different tested bacterial strains the

methanolic fruit extract of F vulgare inhibited the growthof Staphylococcus aureus and Bacillus pumilus with 1127 and1267mm zone of inhibition respectively [7]

Several studies indicating the antifungal effect of Fvulgare along with antibacterial effect are also reported inthe literature Martins et al [94] investigated the antibacterialand antifungal effects of three essential oils of Portugueseplants namely Foeniculum vulgareMentha spicata and Ros-marinus officinalis against Staphylococcus aureus Escherichiacoli Klebsiella pneumonia Pseudomona aeruginosa Staphy-lococcus epidermidis Candida albicans and phytopathogenic

diseases [97] In an in vitro study aqueous and alcoholicseed extracts of F vulgare exhibited inhibitory effect againstAlternaria alternata Mucor rouxii and Aspergillus flavus[98] Interestingly aqueous seed extract of F vulgare showedstrongest antifungal activity as compared to reference fungi-cidal agent that is griseofulvin [99]

All of the above mentioned studies were carried outon the crude extracts and it is difficult to pinpoint theactive antimicrobial metabolite A phenylpropanoid deriva-tive called dillapional characterized from F vulgare stem wasfound to be an antimicrobial constituent with MIC values of125 250 and 125 against Bacillus subtilis Aspergillus nigerand Cladosporium cladosporioides respectively A coumarinderivative scopoletin was also isolated as a marginallyantimicrobial agent [100] The characterization of sevendifferent types of oxygenatedmonoterpenes frommethylene

chloride crude extract of F vulgare [101] suggested thatthe crude extract containing monoterpenes could be a newmedicinal resource for antibacterial agents

A total of 78 compounds were identified from theactive antimycobacterial fraction of F vulgare with thehelp of gas chromatography-mass spectra (GC-MS) Outof these twenty compounds were tested against one sensi-tive and three MDR strains of Mycobacterium tuberculosisusing the Alamar Blue microassay Compounds that showedsome degree of antimycobacterial activity against all strainstested were the following linoleic acid (MIC 100 120583gmL)oleic acid (MIC 100 120583gmL) 13-benzenediol (MIC 100ndash200120583gmL) undecanal (MIC 50ndash200120583gmL) and 24-undecadienal (MIC 25ndash50120583gmL) 24-Undecadienal wasthe most active compound against multidrug resistant Mtuberculosis speciesThus the dietary intake of F vulgaremaylower the risk ofM tuberculosis infection [63]

Orhan et al [5] studied the antiviral activity of theessential oil of fruit sample of F vulgare along with 12other Turkish medicinal plants against the DNA virusHerpessimplex type-1 (HSV-1) and the RNA virus parainfluenzatype-3 (PI-3) Most of the oils and compounds displayedstrong antiviral effects against HSV-1 ranging between 08and 0025 120583gmL However the samples tested were lesseffective against PI-3 with results ranging between 16 and02 120583gmL Only the essential oils of Anethum graveolensFoeniculum vulgare (fully mature) Mentha piperita Menthaspicata Ocimum minutiflorum Ocimum vulgaris and Sat-ureja cuneifolia inhibited this virus significantly

All these literature findings validated the traditional usesof Foeniculum vulgare in infectious disorders like abdomi-nal pains antiemetic arthritis conjunctivitis constipationdepurative diarrhea dieresis fever flatulence gastralgia gas-tritis insomnia irritable colon mouth ulcer stomachacherespiratory disorders skin diseases and so forth There isalways a need for new antimicrobial agents due to rapiddevelopment of resistance Bioactive metabolites of F vulgaremay be a potential source for new antimicrobial agents

42 Anti-Inflammatory Activity Oral administration ofmethanol extract of F vulgare fruit to rat and mice exhibitedinhibitory effects against acute and subacute inflammatorydiseases The anti-inflammatory activity of methanol extractwas evaluated by using three screening protocols namelycarrageenan-induced paw edema arachidonic acid-inducedear edema and formaldehyde-induced arthritis Theseare widely used for testing nonsteroidal anti-inflammatorydrugs For acute inflammationmethanol extract (200mgkg)exhibits significant inhibition of paw edema (69) inducedby carrageenan injection as compared to the control groupof animals Methanol extract of F vulgare also inhibitsear-edema (70) induced by arachidonic acid in mice Thelevel of serum transaminase aspartate aminotransferase(AST) and alanine aminotransferase (ALT) significantlyincreases in the presence of methanolic extract of F vulgareon inflammation induced by formaldehyde as comparedto control group The assessment of the level of AST and

ALT provides a good and simple tool to measure the anti-inflammatory activity of the target compounds [102] Theseoverall results seem to suggest that F vulgare FME mayact on both the cyclooxygenase and lipoxygenase pathways[79]

43 Antiallergic Activity Methanolic extract of F vulgarefruit showed significant inhibitory effect on DNFB- (24-dinitrofluorobenzene-) induced delayed type hypersensitiv-ity after oral administration of 200mgkg once a day for7 days The inhibitory effect on immunologically inducedswelling suggests the possible immunosuppressive propertiesof F vulgare [79]

44 Hepatoprotective Activity Essential oil of F vulgareseeds revealed a potent hepatoprotective effect against acutehepatotoxicity produced by carbon tetrachloride in ratsOral administration of F vulgare essential oil decreases thelevels of serum aspartate aminotransferase (AST) alanineaminotransferase (ALT) alkaline phosphatase (ALP) andbilirubin as compared to the control group Ozbek et alsuggest that the constituents (d-limonene and 120573-myrcene) ofessential oil may have played a key role in the protection ofliver from CCl

4toxicity [9]

45 Anxiolytic Activity Anxiety is the unpleasant feeling offear and concern When anxiety becomes excessive it maybe considered as an anxiety disorder Anxiolytic fennel isa drug used for the treatment of anxiety and its relatedpsychological and physical symptoms Naga Kishore et al[89] investigated the anxiolytic activity of ethanolic extract ofF vulgare fruit with the help of elevated plus maze rota rodopen field test and whole board models The 100 to 200mgdose of extract per kg of body weight of animal revealedsignificant activity when compared to reference anxiolyticdrug called diazepam (1mgkg) Thus fennel extract maypossess anxiolytic activity supporting its traditional claimabout anxiolytic activity reported in 19th edition of Pharma-cology and Pharmacotherapeutics by Sathodkar Bhandarkarand Rege

46 Antistress Activity Drug and food of natural originplay a significant role in public healthcare systems and arebeing investigated as remedies for a number of stress-relateddisorders [103]Thewhole plant extract of F vulgare exhibitednotable antistress effect against stress induced by forcefulswimming of test animals The key parameters that isurinary levels of vanillyl mandelic acid (VMA) and ascorbicacid in rats were used to evaluate antistress activity Theplant extract (50 100 and 200mgkg body weight) showeda significant improvement in urinary levels of VMA (119875 lt0001) and ascorbic acid excretion levels (119875 lt 0001) in testanimals when compared to the normal basal levels in controlgroup of animalsThus the extract of entire plant of F vulgareacts as an antistress agent [13]

47 Memory-Enhancing Property There are a number ofplants whose consumption is believed to enhance memory

22 BioMed Research International

and intelligence These were usually given to children as partof their food F vulgaris an ayurvedic rasayana (mixture)possessing multiple neuropharmacological activities Theantidepressant activity of fennel has been well documentedin ethnomedicine The whole plants extract (50 100 and200mgkg) of F vulgare exhibited memory-enhancing effectagainst scopolamine-induced amnesic rats This experimentwas evaluated by conditioned avoidance response (CAR)technique The CAR of rats administered with the extractincreased gradually to 95 over 7 to 12 days The acquisition(time to achieve 95 CAR) for rats administered with theextract was dose- and time-dependent compared to controlgroup which took 12 days for acquisition The percentavoidance was always higher in the extract-treated groupsas compared to control group Animals receiving 200mgkgbody weight of the extract took ten days while groups treatedwith 100 and 50mgkg doses of the extract required elevenand twelve days respectively to reach the point of acquisitionAdministration of scopolamine produced amnesia as seenfrom reduction in the observed CAR Amnesia was greaterin the control group than in extract-treated groups How-ever continued treatment with F vulgare produced betterretention and recovery in a dose-dependent manner thanthe vehicle-treated animals Recovery from scopolamine-induced amnesia in the extract-treated groups took 3ndash5 dayswhen compared to normal (control) group which took over6 days This overall progress suggests that F vulgare extractpossesses memory-enhancing property [13]

48 Nootropic Activity Alzheimerrsquos disease is a neurode-generative disorder associated with a decline in cognitiveabilities Dementia is one of the age-related mental problemsand a characteristic symptom of Alzheimerrsquos disease Thereis some evidence in favor of use of F vulgare for the treat-ment of cognitive disorders like dementia and Alzheimerrsquosdisease Methanol extract of the whole plant of F vul-gare administered for eight successive days ameliorated theamnesic effect of scopolamine and aging-induced memorydeficits inmiceThis extract increased step-down latency andacetylcholinesterase inhibition in mice significantly Thus Fvulgaremay be employed in treatment of cognitive disorderssuch as dementia and Alzheimerrsquos disease as a nootropic andanticholinesterase agent [80]

49 Antihirsutism Activity Idiopathic hirsutism is definedas the occurrence of excessive male pattern hair growth inwomen who have a normal ovulatory menstrual cycle andnormal levels of serum androgens It may be a disorder ofperipheral androgen metabolism Traditionally Foeniculumvulgare has been used as an estrogenic agent It has beenreputed to increase milk secretion promote menstruationfacilitate birth and increase libido On considering aboveaspect Javidnia and his research team evaluated the antihir-sutism activity of ethanolic extract of F vulgare seed againstidiopathic hirsutism by preparing cream containing 1 and 2of fennel extract The efficacy of treatment with the creamcontaining 2 fennel is better than the cream containing 1fennel and these two were more potent than placebo (control

group) The mean values of hair diameter reduction were78 183 and minus05 for patients receiving the creamscontaining 1 2 and 0 (placebo) respectively [78]

410 Estrogenic Properties Since the discovery of the estrusinducing effects of some plant products in 1926 consider-able effort has been devoted towards the characterizationof phytoestrogens including flavonoids isoflavonoids chal-cones coumestans stilbenes lignans saponins and essentialoils [16] F vulgare has estrogen-like activity In male ratstotal concentration of protein was found to be significantlydecreased in testes and in vasa deferentia whereas increasedin seminal vesicles and in prostate gland On the otherhand simultaneous decrease in the activities of acid andalkaline phosphatase in all these regions (except that alka-line phosphatase was unchanged in vasa) due to the oraladministration of acetone extract of F vulgare fruit wasobserved In female rats oral administration of the extract for10 days led to vaginal cornification and oestrus cycle [8] Totalconcentration of nucleic acids and protein as well as the organweights increased in both the tissues namely mammaryglands and oviducts due to the oral administration of acetoneextract (50 150 and 250120583g100 g body wt) of F vulgare seeds[104] Fennel oil was reported to exhibit estrogenic activitypromote menstruation and alleviate the symptoms of femaleclimacteric and increase libido [71] Administration of fenneloil (25 and 50 120583gmL final concentration in the organ bath)failed to exhibit any remarkable effect in uterine contrac-tion While 10 20 and 40 120583gml concentration of fennel oilrevealed significant inhibitory effect against prostaglandinE2 Fennel oil significantly reduces the frequency of uterinecontraction induced by prostaglandin E2 Thus the extractsof F vulgare have strong estrogenic activity [76]

411 Galactogenic Activity Foeniculum vulgare has been usedformillennia to increasemilk secretion [105]Thus F vulgarebelongs to galactagogue substance Structural similarity ofits main constituent anethole to dopamine seems to beresponsible for galactogenic activityDopamine acts to inhibitthe secretion of the milk-producing hormone prolactinAnethole might influence milk secretion by competing withdopamine at the appropriate receptor sites thereby inhibitingthe antisecretory action of dopamine on prolactin [71] It wasreported that anol (demethylated anethole) causes growthof the lobule-alveolar system in the mammary glands ofimmature female rabbits and induces menstruation in miceand other experimental animals Anol also gave positiveresults in the Jadassohn nipple test a test which involvesthe measurement of changes induced in the nipples ofguinea pigs subjected to the cutaneous application of sexhormones However further research suggests that the actualpharmacologically active agents responsible for galactogenicactivity are polymers of anethole such as dianethole andphotoanethole rather than anol or anethole itself [20 76]

412 Expectorant Activity F vulgare seeds stimulate theciliary motility of the respiratory apparatus and enhance the

BioMed Research International 23

external transport of extraneous corpuscles This action sug-gests a use for fennel in treating bronchial and bronchopul-monary afflictions and in particularly polluted environments[106] The volatile oil of F vulgare stimulates the contractionof the smooth muscles of the trachea an action that couldfacilitate the expectoration of mucus bacteria and othercorpuscles extraneous to the respiratory tracts [74]

413 Anticolitic Activity Essential oil of fennel regulates themotility of smooth muscles of the intestine while at thesame time reducing intestinal gas Alone or combined withother plant medicinals Foeniculum vulgare is indicated in thetreatment of spastic gastrointestinal disturbances in someforms of chronic colitis (which resist other treatments) indyspepsias from gastrointestinal atony in dyspepsias withthe sensation of heaviness in the stomach and so forthTheaddition of fennel to preparations containing anthraquinoniccomponents reduces the occurrence of abdominal pain oftenassociated with this type of laxative [73]

414 Antinociceptive Activity Antinociceptive means anysubstance that inhibits nociception which is a physiologicalprocess underlying the sensation of pain Briefly it reducesthe sensitivity to painful stimuli The various extracts ofaerial part of F vulgare namely hexane methylene chlorideethyl acetate and methanolic extract showed remarkableantinociceptive activity against acetic acid induced writhingin mice [68] The methanolic extract of the aerial parts ofF vulgare exhibited the highest antinociceptive activity at adose level of 2000mgkg while the activity exhibited by theethyl acetate extract was at dose level 800mgkgOn the otherhand n-hexane extract (700mgkg) and methylene chlorideextract (500mgkg) exhibited similar antinociceptive activi-ties being less than peripheral antinociceptive reference drug(acetyl salicylic acid) [68]

415 Diuretic Activity A diuretic is any substance thatpromotes the production of urine Briefly it is an agentthat promotes diuresis Diuretics work by promoting theexpulsion of urine (measured as the urine volume [UV]excreted) and urinary sodium (UNa) from the body and thishelps reduce the volume of blood circulating through thecardiovascular system Caceres et al [107] performed a studyin conscious animals and administered a powdered extractof the whole plant (F vulgare) which had no effect on UVor UNa The ethanolic extract of F vulgare fruit revealedexcellent diuretic activity and proves the earlier folk claimof F vulgare which was reported in the United State ofAmerica (Table 5) The fruit extract showed statistically ahighly significant diuretic effect F vulgare induced diuresis(500mgkg dose)was comparable to that of reference diureticagent urea (960mgkg dose) in mice with a urine outputthat was almost double that of the control group Thediuresis was not associated with changes in sodium andorpotassium excretion [108] In another part of the study theauthors showed that Foeniculum vulgare had little effect onthe noradrenalin contractile responses of aortic rings thus

suggesting that it worked mainly as a diuretic and natriureticwith little effect on arterial vascular tone [77]

416 Cardiovascular Activity An aqueous extract of F vul-gare leaves possesses potential cardiovascular action Thiseffect was investigated using pentobarbital-anaesthetisedmale albino Sprague-Dawley rats [75] An intravenousadministration of the lyophilized boiled water extract ofleaves produced a significant dose-related reduction in arte-rial blood pressure without affecting the heart rate or respi-ratory rate On the other hand the nonboiled aqueous extractshowed very little hypotensive activityThe hypotensive effectof the boiling water extract appeared not to be mediated viaadrenergicmuscarinic ganglionic or serotonergic receptorshowever histamine antagonists inhibited the hypotensiveeffect in a dose-related manner [75]

417 Oculohypotensive Activity The aqueous seed extract ofF vulgare demonstrated significant oculohypotensive activityusing water loading and steroid induced glaucoma modelThis extract exhibited 1749 2116 and 2203 reduction ofintraocular pressure in normotensive rabbits at 03 06and 12 (wv) concentrations respectively A maximummean difference of 3120 was observed between vehiclestreated and extracts treated eyes in water loading experi-mental animal model while a maximum mean intraocularpressure lowering of 3129 was observed in steroid inducedmodel of glaucoma Thus the aqueous extract of F vulgarerevealed oculohypotensive activity which was found to be asgood as that of reference standard antiglaucoma drugs calledtimolol [84]

418 Antithrombotic Activity Tognolini et al [55] providedevidence of potent inhibitory activity of essential oil of F vul-gare against platelet aggregation induced byADP arachidonicacid and collagen in guinea pig plasma Similar findingswere reported by Yoshioka and Tamada [109] for aggregationof rabbit platelets by an aromatic factor of fennel oil Theessential oil and anethole (a constituent of oil) of F vulgaretested in vitro in rat aorta with or without endotheliumdisplayed comparable NO-independent vasorelaxant activityat antiplatelet concentrations It supports the safety of Fvulgare that is free from cytotoxic effects Anethole and Fvulgare did not cause cytotoxicity when incubated for 30minupto 300 120583gmL in platelet viability test This concentrationwas largely compatible with those adopted in the functionalin vitro tests In vivo both F vulgare essential oil andanethole orally administered in a subacute treatment to mice(30mgkgday for 5 days) showed significant antithrom-botic activity preventing the paralysis induced by collagen-epinephrine intravenous injection (70 and 83 protectionresp)Thus essential oil and its main component anethole ofF vulgare showed a safe antithrombotic activity in guinea pigplasma that seems due to their broad spectrum antiplateletactivity clot destabilizing effect and vasorelaxant action [55]

419 Antimutagenic Effect Essential oil of F vulgare revealednoteworthy protective effects against genotoxicity in mice

24 BioMed Research International

induced by cyclophosphamide Genotoxicity and cytotoxicitywere assessed by using mice bone marrow chromosomalaberration micronucleus and sperm abnormality assaysrespectively Oral administration of essential oil (1 and2mLkg) significantly inhibited the frequencies of aberrantmetaphases chromosomal aberrations micronuclei forma-tion and cytotoxicity in mouse bone marrow cells inducedby cyclophosphamide and also produced a significant reduc-tion of abnormal sperm and antagonized the reduction ofcyclophosphamide induced superoxide dismutase catalaseand glutathione activities and inhibited increased malondi-aldehyde content in the liver Additionally F vulgare inhibitsthe oxidative stress induced by cyclophosphamide [90]

420 Gastrointestinal Effect Theaqueous extract of F vulgareshowed remarkable antiulcerogenic effect against ethanol-induced gastric lesions in rats It was found that pretreatmentwith aqueous extract significantly reduced ethanol-inducedgastric damageThis effect of aqueous extract was highest andstatistically significant in 300mgkg group comparedwith thecontrol (119875 lt 0001) group of animal Additionally aqueousextract of F vulgare significantly reduced the whole bloodmalondialdehyde levels while significantly increased nitritenitrate ascorbic acid retinol and beta-carotene levels Thusaqueous extract of F vulgare fruit had clearly a protectiveeffect against ethanol-induced gastric mucosal lesion in rats[81]

421 Chemomodulatory Action The chemopreventive effectof different doses of test diet of Foeniculum vulgare seeds wasexamined against 712-dimethylbenz(a)anthracene- (DMBA-) induced skin papillomagenesis and benzo(a)pyrene-[B(a)P-] induced forestomach papillomagenesis at the peri-initiational level in Swiss albino mice Fennel seeds exhibita significant reduction in the skin and the fore-stomachtumor incidence and tumor multiplicity as compared tothe control group Further biochemical assays showeda significant increase in the contentactivities of phase Ienzymes especially in the case of 6 test diet A concomitantincrease in the activities of the phase II enzymes wasobserved with all the doses of test diet under study Asignificant enhancement in the activities of antioxidantenzymes was observed especially at 4 and 6 test diets offennel These findings were indicative of chemopreventivepotential of fennel against carcinogenesis This is the firstreport showing chemopreventive potential of seeds of fennelagainst carcinogenesis [85]

422 Cytoprotection and Antitumor Activity Anethole is theprincipal active component of fennel seeds which has exhib-ited anticancer activity Al-Harbi et al studied the antitumoractivity of anethole against Ehrlich ascites carcinoma inducedin a tumor model in Swiss albino mice The study revealedthat anethole increased survival time reduced tumor weightand reduced the volume and body weight of the Ehrlichascites tumour-bearing mice It also produced a significantcytotoxic effect in the Ehrlich ascites tumour cells in the pawreduced the levels of nucleic acids and malondialdehyde and

increased glutathione concentrations [110] In vitro cytopro-tection activity of methanolic extract of Foeniculum vulgarewas evaluated against normal human blood lymphocytes bymicronucleus assay and antitumor activity against B16F10melanoma cell line by Trypan blue exclusion assay for cellviability Lymphocyte culture treated with 70 methanolicextract of Foeniculum vulgare showed very less percentage ofmicronucleus that is 0006 as compared to standard drugdoxorubicin which showed 0018 micronucleus On theother hand 70methanolic extract of Foeniculum vulgare haspotent antitumor activity at the concentration of 200120583gmLThe results suggest that the Foeniculum vulgare could beconsidered as a natural resource of antitumor agents as wellas cytoprotective to normal cells [11]

423 Cytotoxicity Kaileh and his coworker investigated thecytotoxic effect of organic extracts of 24 selected Palestinianmedicinal plant species The plant selection was based onexisting ethnobotanic information and interviews with localhealers The extracts of the plants under investigation weretested for their potential antitumor (cytotoxic) effect on themurine fibrosarcoma L929sA cells and on the human breastcancer cells MDA-MB231 and MCF7 The extract from Fvulgare presented an IC (50) value at 24 h of 700 plusmn 28 and500plusmn17 120583gmL on L929sA andMCF7 cells respectivelyThenuclear transcription factor NFkappaB or NF120581B regulatesthe expression of various genes They further investigatedthe effect of nine promising plant extracts withheld fromthe first cell viability screening on NF120581B activation Thedichloromethane and methanol (1 1) extract of aerial part ofF vulgare revealed immunomodulatory NF120581B activities [82]Also Berrington and Lall investigated the in vitro cytotoxicityof acetone extracts of F vulgare and other eight medicinalplants against a noncancerous African green monkey kidney(Vero) cell line and an adenocarcinoma cervical cancer(HeLa) cell line [87]

424 Antipyretic Activity F vulgare extract showedantipyretic activity against hyperpyrexia in mice It wasinduced by SC administration of 2mL100 g of a 20aqueous suspension of brewerrsquos yeast As an antipyreticagent ethanolic extract of F vulgare fruit showed a moderateantipyretic activity that was statistically significant after 30and 90min (119875 lt 001) [108]

425 Hypolipidemic Activity The aqueous extract of F vul-gare revealed notable hypolipidemic and antiatherogenicactivity against Triton WR-1339 induced hyperlipidemiain mice Aqueous extract causes significant reduction ofplasma lipid levels that is cholesterol triglycerides LDL-cholesterol and apolipoprotein-B decreased by 40 2361 and 61 respectively and increase in HDL-cholesteroland apolipoprotein A1 by 85 and 58 respectively [88]

426 Hypoglycemic Activity The essential oil of F vulgareexhibits potential hypoglycemic and antioxidant activityagainst streptozotocin induced diabetes in rats Essentialoil (30mgkg body weight) of F vulgare works in the

427 Antispasmodic Activity The antispasmodic activity of25 and 100mLL of alcoholic extract of Foeniculum vulgarealong with other Germanic medicinal plants namelyMelissaofficinalis Rosmarinus officinalisMentha piperitaMatricariachamomilla Carum carvi and Citrus aurantium were testedemploying the guinea pig ileum and using acetylcholine andhistamine as spasmogens An alcoholic extract of the fruits ofFoeniculum vulgare possesses antispasmodic activity whichinhibits the acetylcholine and histamine-induced guineapig ileal contractions in vitro An essential oil which isobtained from the fruits of Foeniculum vulgare 25 120583gmL and10 120583gmL respectively inhibited oxytocin and prostaglandin[72]

428 Apoptotic Activity The apoptotic activities of ethanolextracts from fruits of seven species of Apiaceae familynamely Eryngium planum Archangelica officinalis Pasti-naca sativa Heracleum sibiricum Carum carvi Foenicu-lum vulgare and Levisticum officinale against ML-1mdashhumanacute myeloblastic leukaemia J-4501mdashhuman acute Tcell leukaemia EOLmdashhuman eosinophilic leukaemia HL-60mdashhuman Caucasian promyelocytic leukaemia 1301mdashhuman T cell leukaemia lymphoblast C-8166mdashhuman Tcell leukaemia U-266B1mdashhuman myeloma WICLmdashhumanCaucasian normal B cell and H-9mdashhuman T cell wereinvestigated with the help of Trypan blue assay and AnnexinV fluos assay [86] The ethanol extract from fruit F vulgareshowed the highest mortality in Trypan blue test for J45cell linemdash4 of viable cells and for C8166 cell linemdash100of mortality However the cells of other lines showed thehighest viability HL60mdash60 EOLmdash48 and MLmdash1ndash42The normal cell line H9 and WICL showed 35 and 25of viable cells respectively C8166 cell line and J-45 cell lineshowed the highest level of the apoptotic cells detected byAnnexin V methodmdash100 and 93 respectively Howeverthe cells of two lines HL60 and EOL-1 showed the lowerlevels of apoptotic cellsmdash52 and 60 respectively Highpercentage of apoptotic cells was observed inH9 andWICLmdash76 and 93 respectively [86]

429 Human Liver Cytochrome P450 3A4 Inhibitory ActivityThirteen compounds isolated from the methanolic extract offennel have been found to possess human liver cytochromeP450 3A4 inhibitory activity Among these compounds 5-methoxypsoralen (5-MoP) showed the strongest inhibitionwith an IC50 value of 183120583m and with a mixed type ofinhibition [83]

430 Antiaging Effects Rasul and his coworker developeda base and formulation containing 4 concentrated seedextract of F vulgare This formulation shows notable antiag-ing effect with supporting experimental data related to skinmoisture and transepidermal water loss (TEWL) The basewas insignificant while the formulation showed significanteffects on skin moisture and TEWL The texture parameterenergy showed a significant increase proving that the formu-lation possesses potential antiaging effects [50]

431 Bronchodilatory Effect Ethanol extract and essential oilfrom F vulgare exhibited bronchodilatory activity on con-tracted tracheal chains of guinea pig The potassium channelopening effect of fennel may contribute on its relaxant effecton guinea pig tracheal chains [111] Moreover anethole bearsa striking resemblance to the catecholamines epinephrinenorepinephrine and dopamine This structural similarityappears to be responsible for the various sympathomimeticactivities of F vulgare such as bronchodilatory effect [71]

432 Antioxidant Activities Naturally occurring antioxi-dants can be used to protect human beings from oxidativestress damage [112] Fennel was known as excellent source ofnatural antioxidants and contributed to the daily antioxidantdiet [113]Wild fennel was found to exhibit a free radical scav-enging activity with higher content phenolic and flavonoidthan medicinal and edible fennel and the aerial parts ofthe Italian fennel populations showed the highest DPPHscavenging activity [65] Phenolic compounds of fennelincluding caffeoylquinic acid rosmarinic acid eriodictyol-7-orutinoside quercetin-3-O-galactoside and kaempferol-3-O-glucoside showed antioxidant activities [67] The volatileoil showed strong antioxidant activity in comparison withbutyrated hydroxyanisole and butylated hydroxytolueneEthanol and water extracts of fennel showed less antioxidantactivity compared with essential oil [114]

5 Environmental Application

Foeniculum vulgare that is fennel not only exhibited phar-macological activities but also revealed a few environmentalactivities These activities play a key role in the managementof nematode insect mosquitoes and some harmful larvae ofmalaria producing vector Thus the extracts of F vulgare andisolated biologically active compounds have been evaluatedfor their insecticidal repellent acaricidal larvicidal andnematicidal activity [115ndash119] A brief review on the differenttype of ecofriendly environmental activities as reported onthis plant is summarized below

51 Insecticidal Activities The fruit derived phytoconstitu-ents of F vulgare exhibited prominent insecticidal activi-ties against Sitophilus oryzae Callosobruchus chinensis andLasioderma serricorne This activity was examined usingdirect contact application and fumigation methods Thebiologically active constituents that is phenylpropenes (E)-anethole and estragole and the monoterpene (+)-fenchonewere characterized from Foeniculum fruit By using a filter

26 BioMed Research International

paper diffusion test estragole (0168mg cmminus2) caused 91mortality to S oryzae within 1 day after treatment whereas(+)-fenchone and (E)-anethole gave over 90 mortality at 2and 4 day after treatment respectively

After 2 days of treatment all test compounds (0021mg cmminus2 concentration) revealed potent insecticidal activityagainst C chinensis Whereas after 1 day of treatment (E)-anethole (0105mg cmminus2) gave 100mortality of L serricornewhereas 90 and 60 mortality at 4 day after treatment wasachieved with estragole and (+)-fenchone respectively In afumigation test the compounds were much more effectiveagainst adults of S oryzae C chinensis and L serricorne inclosed cups than in open ones indicating that the insecticidalactivity of test compounds was largely attributable to fumi-gant action As naturally occurring insect-control agents theF vulgare fruit-derived materials described could be usefulfor managing field populations of S oryzae C chinensis andL serricorne [116]

52 Acaricidal Activity Fennel oil shows significant acaricid-al activity againstDermatophagoides farinae andDermatoph-agoides pteronyssinus (+)-fenchone and p-anisaldehyde aremajor constituents of fruit oil of F vulgare P-anisaldehydewas the most toxic compound against D farinae and is muchmore effective compared with benzyl benzoate thymol andestragol [118]

53 Repellent Activity The methanolic extract of fruits ofF vulgare was spectroscopically characterized for the pres-ence of biologically active constituents called (+)-fenchoneand (E)-9-octadecenoic acid The repellent activity of theseconstituents was tested against hungry Aedes aegypti femaleswith the help of skin and patch tests and compared withthat of the commercial repellent agent called NN-diethyl-m-toluamide (DEET) and (Z)-9-octadecenoic acid In askin test with female mosquitoes (+)-fenchone and (Z)-9-octadecenoic acid (04mgcm2) exhibitedmoderate repellentactivity at 30min after treatment whereas DEET providedgt1 h of protection against adult mosquitoes at (02mgcm2)Thus (+)-Fenchone and (E)-9-octadecenoic acid are poten-tial mosquito repellent agents or lead compounds [117]

54 Larvicidal Activity Plant extracts and oils may act asalternatives to conventional pesticides for malaria vectorcontrol By considering this aspect Sedaghat et al [119] inves-tigated the larvicidal activity of essential oils of three plantsof Apiaceae family against malaria vector called Anophe-les stephensi The larvicidal activity was evaluated againstlaboratory-reared larvae by standard method of WHO TheF vulgare oil was the most effective against A stephensiwith LC(50) and LC(90) values of 2010 and 4451 ppmrespectively [119] Additionally the essential oil extracts fromleaves flowers and roots of F vulgare exhibit noticeablelarvicidal activity against fourth-instar larvae of themosquitoCulex pipiens molestus Terpineol and 18-cineole content of Fvulgare are the most effective phytoconstituent against Culexpipiens molestus bites offering complete protection for 16 and2 h respectively [120] Recently Zoubiri et al [57] reported

the larvicidal activity of essential oil of fennel seed againstCulex pipiensmosquitoThus F vulgare can serve as a naturallarvicidal agent

55 Nematicidal Activity Oka et al investigated the in vitronematicidal activity of essential oils extracted from 27 spicesand aromatic plants in pot experiments Twelve of thetwenty-seven essential oils immobilized more than 80 ofjuveniles of the root-knot nematodeMeloidogyne javanica ata concentration of 1000 120583Lliter At this concentration mostof these oils also inhibited nematode hatching Essential oilsof Carum carvi Foeniculum vulgare Mentha rotundifoliaand Mentha spicata showed the highest nematicidal activityamong the in vitro tested oils In 3-liter pot experimentsnematicidal activity of the essential oils and their componentswas confirmed at 200 and 150mgkg respectivelyThe resultssuggest that the essential oils and theirmain componentsmayserve as nematicides [115]

6 Toxicity

The long history of ethnomedicinal application with noreports of any serious side effects suggests that F vulgarecould be considered as safe Inmost toxicity experiments car-ried out on F vulgare no sign of toxicity was observed Shahand his coworker in 1991 investigated the detailed toxicityaccount of ethanolic extract of fennel fruit in experimentalmice with respect to acute and 90 days longer term toxicity[121] In experimentation Shah and his coworker observedthe general symptoms of toxicity and mortality for only 24 hin acute toxicity Whereas in another part of toxicity theystudied the effect of fennel extract on mice with 90 dayslong term treatment Acute toxicity of ethanolic extract of Fvulgarewas assessed in 35mice by using three concentrationsnamely 05 1 and 3 gkg body weight In this investigation Fvulgare exhibited no signs of toxicity and no mortality wasobserved upto the dose level 3 gkg body weight In case oflonger term toxicity ethanolic extract of F vulgare (100mgkgbody weightday) was given in drinking water of animals(30 male and 30 female mice) All external morphologicalhaematological and spermatogenic changes in addition tobody and vital organ weights were recorded The extractcaused no significant chronic mortality as compared tocontrols during this investigation The treated male micegained significant weight during chronic treatment while aloss or no significant change in weight was noticed in thefemale mice treated with the same extract The extracts didnot show spermatotoxic effects Thus Shah and his coworkerconcluded that fennel extract is safe based on both acuteandor long term toxicity studies [121] Additionally the plantextract in doses of 05 1 and 3 gkg (orally) did not causeany deaths These doses do not show any type of toxicityagainst several parameters tested namely locomotor activitybizarre reactions sensitivity to sound social interaction tailposture aggressive behaviour ataxia paralysis convulsionstremors prostration exophthalmos pupil size defecationsalivation urination pattern of respiration nasal dischargecyanosis and piloerection Exceptionally only the 3 gkg dose

BioMed Research International 27

showed signs of reduced locomotor activity and piloerec-tion Otherwise all other parameters were negative [108]In another experiment of acute toxicity different solventextracts namely n-hexane methylene chloride ethyl acetateand methanol extracts of F vulgare upto 55 gkg concentra-tion did not revealed any kind of toxicity in mice LD50being 675 110 692 and 15 gkg for n-hexane methylenechloride ethyl acetate and methanol extracts respectively[68] The plant extract of F vulgare was administered orallyat a dose of 100 200 400 600 800 1000 and 2000mgkgof body weight of mice Each group of animals was undervisual observation for 10 days for the external behavior ofneurological toxicity created by plant extract Even the micereceiving highest dose of F vulgare extract did not show anymortality or toxicity demonstrating the safety profile of theplant extract [89]

The acute oral 50 LD50 for anethole in rats was foundto be 2090mgkg Repeated doses of one-third the LD50 ofanethole (695mgkg) given to rat caused mild liver lesionsIt would therefore appear that in normal therapeutic dosagesanethole would have minimal hepatotoxicity When anetholewas fed to rats daily for one year as 025 of the dietno hepatic damage was seen [122] The acute oral LD50 ofessential oil in rats is 1326mgkg [76] The use of F vulgareessential oil as a remedy for control of primary dysmenorrheaincreases concern about its potential teratogenicity due toits estrogen like activity Evaluation of teratogenicity ofessential oil using limb bud mesenchymal cells showed thatthe essential oil may have toxic effect on fetal cells butthere was no evidence of teratogenicity upto concentrationof 93mgmL of culture medium [123] The overall toxicitystudies carried out on F vulgare accounts for its safety at therecommended therapeutic doses

7 Conclusions

The available scientific research on Foeniculum vulgarehas shown that it is an important medicinal plant used ina wide range of ethnomedical treatments especially forabdominal pains antiemetic aperitif arthritis cancer colicin children conjunctivitis constipation depurative diarrheadieresis emmenagogue fever flatulence gastralgia gastritisinsomnia irritable colon kidney ailments as a laxativeleucorrhoea liver pain mouth ulcer and stomachache Thisplant has been in use for a long period of time withoutany documented serious adverse effects Studies carriedout in the past and present indicate that fennel possessesdiverse health benefits and are an important constituentof food Studies have shown that various extracts offennel possess a range of pharmacological actions such asantiaging antiallergic anticolitic antihirsutism anti-inflam-matory antimicrobial and antiviral antimutagenic antino-ciceptive antipyretic antispasmodic antistress antithromb-otic anxiolytic apoptotic cardiovascular chemomodulatoryaction cytoprotection and antitumor cytotoxicity diureticestrogenic properties expectorant galactogenic gastrointes-tinal effect hepatoprotective human liver cytochrome P4503A4 inhibitory hypoglycemic hypolipidemic memory-en-hancing property nootropic and oculohypotensive activity

supporting its traditional use However the most prominentand the well studied effects are the antimicrobial andantioxidant effects of essential oil of fennel in differentexperimental models The observed health benefits may becredited to the presence of the various phytochemicals likevolatile compounds flavonoids phenolic compounds fattyacids and amino acids

Fennel also contains mineral and trace elements likealuminum barium calcium cadmium cobalt chromiumcopper ironmagnesiummanganese nickel lead strontiumand zinc [124] fat soluble vitamins such as vitamins A Eand K water soluble vitamins like ascorbic acid thiamineriboflavin niacin and pyridoxine essential amino acidslike leucine isoleucine phenylalanine and tryptophane maycontribute to the myriad health beneficial effects at least inpart

Most of the pharmacological studies were conductedusing uncharacterized crude extracts of fennel It is difficultto reproduce the results of these studies and pinpoint thebioactive compounds Hence there is a need for chemi-cal standardization and bioactivity-guided identification ofbioactive compounds Among several classes of chemicalconstituents identified in fennel volatile components of fen-nel essential oil and phenolic compounds are assumed to bethe main bioactive compounds responsible for the majorityof its pharmacological effects However the vast traditionaluse and proven pharmacological activities of fennel indicatethat an immense scope still exists for its chemical explorationFuture studies should be focused on validating the mecha-nism of action responsible for the various beneficial effectsand also on understanding which plant based compounds areresponsible for the reported effectsThe required informationwhen available will enhance our knowledge and appreciationfor the use of fennel in our daily diet Also the outcomeof such chemical studies may further expand its existingtherapeutic potential

Thus there are many areas of research related to thisplant that need to be further explored to fully recognize itsbeneficial effects for society Factors such as geographical andseasonal variation play an important role in the authentica-tion of the chemical constituents responsible for the activitywhich also can be an area of interest Thus it is incumbenton researchers to fill the huge gap of insufficient knowledgeand create awareness among pharmacologists as well as inves-tigators towards providing better medicinal value derivedfrom this plant This can be fulfilled only by generatinginterest among the research community through writing ofcritical appraisals (paper) and extending the interdisciplinaryresearch area to focused studies on Foeniculum vulgare

methanolic fruit extract of F vulgare inhibited the growthof Staphylococcus aureus and Bacillus pumilus with 1127 and1267mm zone of inhibition respectively [7]

Several studies indicating the antifungal effect of Fvulgare along with antibacterial effect are also reported inthe literature Martins et al [94] investigated the antibacterialand antifungal effects of three essential oils of Portugueseplants namely Foeniculum vulgareMentha spicata and Ros-marinus officinalis against Staphylococcus aureus Escherichiacoli Klebsiella pneumonia Pseudomona aeruginosa Staphy-lococcus epidermidis Candida albicans and phytopathogenic

molds Aspergillus niger and Fusarium oxysporum Essen-tial oil of F vulgare showed significant antifungal activityagainst the food spoilage fungi Aspergillus niger and Fusar-ium oxysporum and may have important applications asfood additives The MIC values of F vulgare essential oilwere 250120583gmL for Fusarium oxysporum and 750 120583gmLfor Aspergillus niger [94] The oils extracted from F vulgareexhibit varying levels of antifungal effects on the experi-mental mycelial growth of Alternaria alternata Fusariumoxysporum and Rhizoctonia solani [95] Essential oil of Fvulgare showed appreciable antifungal activity against strainsof pathogenic fungi namely Aspergillus niger Fusariumsolani and Rhizopus solani [96] Dichloromethane extractsand essential oils from F vulgare showed antifungal activityagainst Candida albicans It could be a potential candidatefor a new antifungal agent for candidiasis and other fungal

diseases [97] In an in vitro study aqueous and alcoholicseed extracts of F vulgare exhibited inhibitory effect againstAlternaria alternata Mucor rouxii and Aspergillus flavus[98] Interestingly aqueous seed extract of F vulgare showedstrongest antifungal activity as compared to reference fungi-cidal agent that is griseofulvin [99]

All of the above mentioned studies were carried outon the crude extracts and it is difficult to pinpoint theactive antimicrobial metabolite A phenylpropanoid deriva-tive called dillapional characterized from F vulgare stem wasfound to be an antimicrobial constituent with MIC values of125 250 and 125 against Bacillus subtilis Aspergillus nigerand Cladosporium cladosporioides respectively A coumarinderivative scopoletin was also isolated as a marginallyantimicrobial agent [100] The characterization of sevendifferent types of oxygenatedmonoterpenes frommethylene

A total of 78 compounds were identified from theactive antimycobacterial fraction of F vulgare with thehelp of gas chromatography-mass spectra (GC-MS) Outof these twenty compounds were tested against one sensi-tive and three MDR strains of Mycobacterium tuberculosisusing the Alamar Blue microassay Compounds that showedsome degree of antimycobacterial activity against all strainstested were the following linoleic acid (MIC 100 120583gmL)oleic acid (MIC 100 120583gmL) 13-benzenediol (MIC 100ndash200120583gmL) undecanal (MIC 50ndash200120583gmL) and 24-undecadienal (MIC 25ndash50120583gmL) 24-Undecadienal wasthe most active compound against multidrug resistant Mtuberculosis speciesThus the dietary intake of F vulgaremaylower the risk ofM tuberculosis infection [63]

Orhan et al [5] studied the antiviral activity of theessential oil of fruit sample of F vulgare along with 12other Turkish medicinal plants against the DNA virusHerpessimplex type-1 (HSV-1) and the RNA virus parainfluenzatype-3 (PI-3) Most of the oils and compounds displayedstrong antiviral effects against HSV-1 ranging between 08and 0025 120583gmL However the samples tested were lesseffective against PI-3 with results ranging between 16 and02 120583gmL Only the essential oils of Anethum graveolensFoeniculum vulgare (fully mature) Mentha piperita Menthaspicata Ocimum minutiflorum Ocimum vulgaris and Sat-ureja cuneifolia inhibited this virus significantly

All these literature findings validated the traditional usesof Foeniculum vulgare in infectious disorders like abdomi-nal pains antiemetic arthritis conjunctivitis constipationdepurative diarrhea dieresis fever flatulence gastralgia gas-tritis insomnia irritable colon mouth ulcer stomachacherespiratory disorders skin diseases and so forth There isalways a need for new antimicrobial agents due to rapiddevelopment of resistance Bioactive metabolites of F vulgaremay be a potential source for new antimicrobial agents

42 Anti-Inflammatory Activity Oral administration ofmethanol extract of F vulgare fruit to rat and mice exhibitedinhibitory effects against acute and subacute inflammatorydiseases The anti-inflammatory activity of methanol extractwas evaluated by using three screening protocols namelycarrageenan-induced paw edema arachidonic acid-inducedear edema and formaldehyde-induced arthritis Theseare widely used for testing nonsteroidal anti-inflammatorydrugs For acute inflammationmethanol extract (200mgkg)exhibits significant inhibition of paw edema (69) inducedby carrageenan injection as compared to the control groupof animals Methanol extract of F vulgare also inhibitsear-edema (70) induced by arachidonic acid in mice Thelevel of serum transaminase aspartate aminotransferase(AST) and alanine aminotransferase (ALT) significantlyincreases in the presence of methanolic extract of F vulgareon inflammation induced by formaldehyde as comparedto control group The assessment of the level of AST and

ALT provides a good and simple tool to measure the anti-inflammatory activity of the target compounds [102] Theseoverall results seem to suggest that F vulgare FME mayact on both the cyclooxygenase and lipoxygenase pathways[79]

43 Antiallergic Activity Methanolic extract of F vulgarefruit showed significant inhibitory effect on DNFB- (24-dinitrofluorobenzene-) induced delayed type hypersensitiv-ity after oral administration of 200mgkg once a day for7 days The inhibitory effect on immunologically inducedswelling suggests the possible immunosuppressive propertiesof F vulgare [79]

44 Hepatoprotective Activity Essential oil of F vulgareseeds revealed a potent hepatoprotective effect against acutehepatotoxicity produced by carbon tetrachloride in ratsOral administration of F vulgare essential oil decreases thelevels of serum aspartate aminotransferase (AST) alanineaminotransferase (ALT) alkaline phosphatase (ALP) andbilirubin as compared to the control group Ozbek et alsuggest that the constituents (d-limonene and 120573-myrcene) ofessential oil may have played a key role in the protection ofliver from CCl

4toxicity [9]

45 Anxiolytic Activity Anxiety is the unpleasant feeling offear and concern When anxiety becomes excessive it maybe considered as an anxiety disorder Anxiolytic fennel isa drug used for the treatment of anxiety and its relatedpsychological and physical symptoms Naga Kishore et al[89] investigated the anxiolytic activity of ethanolic extract ofF vulgare fruit with the help of elevated plus maze rota rodopen field test and whole board models The 100 to 200mgdose of extract per kg of body weight of animal revealedsignificant activity when compared to reference anxiolyticdrug called diazepam (1mgkg) Thus fennel extract maypossess anxiolytic activity supporting its traditional claimabout anxiolytic activity reported in 19th edition of Pharma-cology and Pharmacotherapeutics by Sathodkar Bhandarkarand Rege

46 Antistress Activity Drug and food of natural originplay a significant role in public healthcare systems and arebeing investigated as remedies for a number of stress-relateddisorders [103]Thewhole plant extract of F vulgare exhibitednotable antistress effect against stress induced by forcefulswimming of test animals The key parameters that isurinary levels of vanillyl mandelic acid (VMA) and ascorbicacid in rats were used to evaluate antistress activity Theplant extract (50 100 and 200mgkg body weight) showeda significant improvement in urinary levels of VMA (119875 lt0001) and ascorbic acid excretion levels (119875 lt 0001) in testanimals when compared to the normal basal levels in controlgroup of animalsThus the extract of entire plant of F vulgareacts as an antistress agent [13]

47 Memory-Enhancing Property There are a number ofplants whose consumption is believed to enhance memory

22 BioMed Research International

and intelligence These were usually given to children as partof their food F vulgaris an ayurvedic rasayana (mixture)possessing multiple neuropharmacological activities Theantidepressant activity of fennel has been well documentedin ethnomedicine The whole plants extract (50 100 and200mgkg) of F vulgare exhibited memory-enhancing effectagainst scopolamine-induced amnesic rats This experimentwas evaluated by conditioned avoidance response (CAR)technique The CAR of rats administered with the extractincreased gradually to 95 over 7 to 12 days The acquisition(time to achieve 95 CAR) for rats administered with theextract was dose- and time-dependent compared to controlgroup which took 12 days for acquisition The percentavoidance was always higher in the extract-treated groupsas compared to control group Animals receiving 200mgkgbody weight of the extract took ten days while groups treatedwith 100 and 50mgkg doses of the extract required elevenand twelve days respectively to reach the point of acquisitionAdministration of scopolamine produced amnesia as seenfrom reduction in the observed CAR Amnesia was greaterin the control group than in extract-treated groups How-ever continued treatment with F vulgare produced betterretention and recovery in a dose-dependent manner thanthe vehicle-treated animals Recovery from scopolamine-induced amnesia in the extract-treated groups took 3ndash5 dayswhen compared to normal (control) group which took over6 days This overall progress suggests that F vulgare extractpossesses memory-enhancing property [13]

48 Nootropic Activity Alzheimerrsquos disease is a neurode-generative disorder associated with a decline in cognitiveabilities Dementia is one of the age-related mental problemsand a characteristic symptom of Alzheimerrsquos disease Thereis some evidence in favor of use of F vulgare for the treat-ment of cognitive disorders like dementia and Alzheimerrsquosdisease Methanol extract of the whole plant of F vul-gare administered for eight successive days ameliorated theamnesic effect of scopolamine and aging-induced memorydeficits inmiceThis extract increased step-down latency andacetylcholinesterase inhibition in mice significantly Thus Fvulgaremay be employed in treatment of cognitive disorderssuch as dementia and Alzheimerrsquos disease as a nootropic andanticholinesterase agent [80]

49 Antihirsutism Activity Idiopathic hirsutism is definedas the occurrence of excessive male pattern hair growth inwomen who have a normal ovulatory menstrual cycle andnormal levels of serum androgens It may be a disorder ofperipheral androgen metabolism Traditionally Foeniculumvulgare has been used as an estrogenic agent It has beenreputed to increase milk secretion promote menstruationfacilitate birth and increase libido On considering aboveaspect Javidnia and his research team evaluated the antihir-sutism activity of ethanolic extract of F vulgare seed againstidiopathic hirsutism by preparing cream containing 1 and 2of fennel extract The efficacy of treatment with the creamcontaining 2 fennel is better than the cream containing 1fennel and these two were more potent than placebo (control

group) The mean values of hair diameter reduction were78 183 and minus05 for patients receiving the creamscontaining 1 2 and 0 (placebo) respectively [78]

410 Estrogenic Properties Since the discovery of the estrusinducing effects of some plant products in 1926 consider-able effort has been devoted towards the characterizationof phytoestrogens including flavonoids isoflavonoids chal-cones coumestans stilbenes lignans saponins and essentialoils [16] F vulgare has estrogen-like activity In male ratstotal concentration of protein was found to be significantlydecreased in testes and in vasa deferentia whereas increasedin seminal vesicles and in prostate gland On the otherhand simultaneous decrease in the activities of acid andalkaline phosphatase in all these regions (except that alka-line phosphatase was unchanged in vasa) due to the oraladministration of acetone extract of F vulgare fruit wasobserved In female rats oral administration of the extract for10 days led to vaginal cornification and oestrus cycle [8] Totalconcentration of nucleic acids and protein as well as the organweights increased in both the tissues namely mammaryglands and oviducts due to the oral administration of acetoneextract (50 150 and 250120583g100 g body wt) of F vulgare seeds[104] Fennel oil was reported to exhibit estrogenic activitypromote menstruation and alleviate the symptoms of femaleclimacteric and increase libido [71] Administration of fenneloil (25 and 50 120583gmL final concentration in the organ bath)failed to exhibit any remarkable effect in uterine contrac-tion While 10 20 and 40 120583gml concentration of fennel oilrevealed significant inhibitory effect against prostaglandinE2 Fennel oil significantly reduces the frequency of uterinecontraction induced by prostaglandin E2 Thus the extractsof F vulgare have strong estrogenic activity [76]

411 Galactogenic Activity Foeniculum vulgare has been usedformillennia to increasemilk secretion [105]Thus F vulgarebelongs to galactagogue substance Structural similarity ofits main constituent anethole to dopamine seems to beresponsible for galactogenic activityDopamine acts to inhibitthe secretion of the milk-producing hormone prolactinAnethole might influence milk secretion by competing withdopamine at the appropriate receptor sites thereby inhibitingthe antisecretory action of dopamine on prolactin [71] It wasreported that anol (demethylated anethole) causes growthof the lobule-alveolar system in the mammary glands ofimmature female rabbits and induces menstruation in miceand other experimental animals Anol also gave positiveresults in the Jadassohn nipple test a test which involvesthe measurement of changes induced in the nipples ofguinea pigs subjected to the cutaneous application of sexhormones However further research suggests that the actualpharmacologically active agents responsible for galactogenicactivity are polymers of anethole such as dianethole andphotoanethole rather than anol or anethole itself [20 76]

412 Expectorant Activity F vulgare seeds stimulate theciliary motility of the respiratory apparatus and enhance the

BioMed Research International 23

external transport of extraneous corpuscles This action sug-gests a use for fennel in treating bronchial and bronchopul-monary afflictions and in particularly polluted environments[106] The volatile oil of F vulgare stimulates the contractionof the smooth muscles of the trachea an action that couldfacilitate the expectoration of mucus bacteria and othercorpuscles extraneous to the respiratory tracts [74]

413 Anticolitic Activity Essential oil of fennel regulates themotility of smooth muscles of the intestine while at thesame time reducing intestinal gas Alone or combined withother plant medicinals Foeniculum vulgare is indicated in thetreatment of spastic gastrointestinal disturbances in someforms of chronic colitis (which resist other treatments) indyspepsias from gastrointestinal atony in dyspepsias withthe sensation of heaviness in the stomach and so forthTheaddition of fennel to preparations containing anthraquinoniccomponents reduces the occurrence of abdominal pain oftenassociated with this type of laxative [73]

414 Antinociceptive Activity Antinociceptive means anysubstance that inhibits nociception which is a physiologicalprocess underlying the sensation of pain Briefly it reducesthe sensitivity to painful stimuli The various extracts ofaerial part of F vulgare namely hexane methylene chlorideethyl acetate and methanolic extract showed remarkableantinociceptive activity against acetic acid induced writhingin mice [68] The methanolic extract of the aerial parts ofF vulgare exhibited the highest antinociceptive activity at adose level of 2000mgkg while the activity exhibited by theethyl acetate extract was at dose level 800mgkgOn the otherhand n-hexane extract (700mgkg) and methylene chlorideextract (500mgkg) exhibited similar antinociceptive activi-ties being less than peripheral antinociceptive reference drug(acetyl salicylic acid) [68]

415 Diuretic Activity A diuretic is any substance thatpromotes the production of urine Briefly it is an agentthat promotes diuresis Diuretics work by promoting theexpulsion of urine (measured as the urine volume [UV]excreted) and urinary sodium (UNa) from the body and thishelps reduce the volume of blood circulating through thecardiovascular system Caceres et al [107] performed a studyin conscious animals and administered a powdered extractof the whole plant (F vulgare) which had no effect on UVor UNa The ethanolic extract of F vulgare fruit revealedexcellent diuretic activity and proves the earlier folk claimof F vulgare which was reported in the United State ofAmerica (Table 5) The fruit extract showed statistically ahighly significant diuretic effect F vulgare induced diuresis(500mgkg dose)was comparable to that of reference diureticagent urea (960mgkg dose) in mice with a urine outputthat was almost double that of the control group Thediuresis was not associated with changes in sodium andorpotassium excretion [108] In another part of the study theauthors showed that Foeniculum vulgare had little effect onthe noradrenalin contractile responses of aortic rings thus

suggesting that it worked mainly as a diuretic and natriureticwith little effect on arterial vascular tone [77]

416 Cardiovascular Activity An aqueous extract of F vul-gare leaves possesses potential cardiovascular action Thiseffect was investigated using pentobarbital-anaesthetisedmale albino Sprague-Dawley rats [75] An intravenousadministration of the lyophilized boiled water extract ofleaves produced a significant dose-related reduction in arte-rial blood pressure without affecting the heart rate or respi-ratory rate On the other hand the nonboiled aqueous extractshowed very little hypotensive activityThe hypotensive effectof the boiling water extract appeared not to be mediated viaadrenergicmuscarinic ganglionic or serotonergic receptorshowever histamine antagonists inhibited the hypotensiveeffect in a dose-related manner [75]

417 Oculohypotensive Activity The aqueous seed extract ofF vulgare demonstrated significant oculohypotensive activityusing water loading and steroid induced glaucoma modelThis extract exhibited 1749 2116 and 2203 reduction ofintraocular pressure in normotensive rabbits at 03 06and 12 (wv) concentrations respectively A maximummean difference of 3120 was observed between vehiclestreated and extracts treated eyes in water loading experi-mental animal model while a maximum mean intraocularpressure lowering of 3129 was observed in steroid inducedmodel of glaucoma Thus the aqueous extract of F vulgarerevealed oculohypotensive activity which was found to be asgood as that of reference standard antiglaucoma drugs calledtimolol [84]

418 Antithrombotic Activity Tognolini et al [55] providedevidence of potent inhibitory activity of essential oil of F vul-gare against platelet aggregation induced byADP arachidonicacid and collagen in guinea pig plasma Similar findingswere reported by Yoshioka and Tamada [109] for aggregationof rabbit platelets by an aromatic factor of fennel oil Theessential oil and anethole (a constituent of oil) of F vulgaretested in vitro in rat aorta with or without endotheliumdisplayed comparable NO-independent vasorelaxant activityat antiplatelet concentrations It supports the safety of Fvulgare that is free from cytotoxic effects Anethole and Fvulgare did not cause cytotoxicity when incubated for 30minupto 300 120583gmL in platelet viability test This concentrationwas largely compatible with those adopted in the functionalin vitro tests In vivo both F vulgare essential oil andanethole orally administered in a subacute treatment to mice(30mgkgday for 5 days) showed significant antithrom-botic activity preventing the paralysis induced by collagen-epinephrine intravenous injection (70 and 83 protectionresp)Thus essential oil and its main component anethole ofF vulgare showed a safe antithrombotic activity in guinea pigplasma that seems due to their broad spectrum antiplateletactivity clot destabilizing effect and vasorelaxant action [55]

419 Antimutagenic Effect Essential oil of F vulgare revealednoteworthy protective effects against genotoxicity in mice

24 BioMed Research International

induced by cyclophosphamide Genotoxicity and cytotoxicitywere assessed by using mice bone marrow chromosomalaberration micronucleus and sperm abnormality assaysrespectively Oral administration of essential oil (1 and2mLkg) significantly inhibited the frequencies of aberrantmetaphases chromosomal aberrations micronuclei forma-tion and cytotoxicity in mouse bone marrow cells inducedby cyclophosphamide and also produced a significant reduc-tion of abnormal sperm and antagonized the reduction ofcyclophosphamide induced superoxide dismutase catalaseand glutathione activities and inhibited increased malondi-aldehyde content in the liver Additionally F vulgare inhibitsthe oxidative stress induced by cyclophosphamide [90]

420 Gastrointestinal Effect Theaqueous extract of F vulgareshowed remarkable antiulcerogenic effect against ethanol-induced gastric lesions in rats It was found that pretreatmentwith aqueous extract significantly reduced ethanol-inducedgastric damageThis effect of aqueous extract was highest andstatistically significant in 300mgkg group comparedwith thecontrol (119875 lt 0001) group of animal Additionally aqueousextract of F vulgare significantly reduced the whole bloodmalondialdehyde levels while significantly increased nitritenitrate ascorbic acid retinol and beta-carotene levels Thusaqueous extract of F vulgare fruit had clearly a protectiveeffect against ethanol-induced gastric mucosal lesion in rats[81]

421 Chemomodulatory Action The chemopreventive effectof different doses of test diet of Foeniculum vulgare seeds wasexamined against 712-dimethylbenz(a)anthracene- (DMBA-) induced skin papillomagenesis and benzo(a)pyrene-[B(a)P-] induced forestomach papillomagenesis at the peri-initiational level in Swiss albino mice Fennel seeds exhibita significant reduction in the skin and the fore-stomachtumor incidence and tumor multiplicity as compared tothe control group Further biochemical assays showeda significant increase in the contentactivities of phase Ienzymes especially in the case of 6 test diet A concomitantincrease in the activities of the phase II enzymes wasobserved with all the doses of test diet under study Asignificant enhancement in the activities of antioxidantenzymes was observed especially at 4 and 6 test diets offennel These findings were indicative of chemopreventivepotential of fennel against carcinogenesis This is the firstreport showing chemopreventive potential of seeds of fennelagainst carcinogenesis [85]

422 Cytoprotection and Antitumor Activity Anethole is theprincipal active component of fennel seeds which has exhib-ited anticancer activity Al-Harbi et al studied the antitumoractivity of anethole against Ehrlich ascites carcinoma inducedin a tumor model in Swiss albino mice The study revealedthat anethole increased survival time reduced tumor weightand reduced the volume and body weight of the Ehrlichascites tumour-bearing mice It also produced a significantcytotoxic effect in the Ehrlich ascites tumour cells in the pawreduced the levels of nucleic acids and malondialdehyde and

increased glutathione concentrations [110] In vitro cytopro-tection activity of methanolic extract of Foeniculum vulgarewas evaluated against normal human blood lymphocytes bymicronucleus assay and antitumor activity against B16F10melanoma cell line by Trypan blue exclusion assay for cellviability Lymphocyte culture treated with 70 methanolicextract of Foeniculum vulgare showed very less percentage ofmicronucleus that is 0006 as compared to standard drugdoxorubicin which showed 0018 micronucleus On theother hand 70methanolic extract of Foeniculum vulgare haspotent antitumor activity at the concentration of 200120583gmLThe results suggest that the Foeniculum vulgare could beconsidered as a natural resource of antitumor agents as wellas cytoprotective to normal cells [11]

423 Cytotoxicity Kaileh and his coworker investigated thecytotoxic effect of organic extracts of 24 selected Palestinianmedicinal plant species The plant selection was based onexisting ethnobotanic information and interviews with localhealers The extracts of the plants under investigation weretested for their potential antitumor (cytotoxic) effect on themurine fibrosarcoma L929sA cells and on the human breastcancer cells MDA-MB231 and MCF7 The extract from Fvulgare presented an IC (50) value at 24 h of 700 plusmn 28 and500plusmn17 120583gmL on L929sA andMCF7 cells respectivelyThenuclear transcription factor NFkappaB or NF120581B regulatesthe expression of various genes They further investigatedthe effect of nine promising plant extracts withheld fromthe first cell viability screening on NF120581B activation Thedichloromethane and methanol (1 1) extract of aerial part ofF vulgare revealed immunomodulatory NF120581B activities [82]Also Berrington and Lall investigated the in vitro cytotoxicityof acetone extracts of F vulgare and other eight medicinalplants against a noncancerous African green monkey kidney(Vero) cell line and an adenocarcinoma cervical cancer(HeLa) cell line [87]

424 Antipyretic Activity F vulgare extract showedantipyretic activity against hyperpyrexia in mice It wasinduced by SC administration of 2mL100 g of a 20aqueous suspension of brewerrsquos yeast As an antipyreticagent ethanolic extract of F vulgare fruit showed a moderateantipyretic activity that was statistically significant after 30and 90min (119875 lt 001) [108]

425 Hypolipidemic Activity The aqueous extract of F vul-gare revealed notable hypolipidemic and antiatherogenicactivity against Triton WR-1339 induced hyperlipidemiain mice Aqueous extract causes significant reduction ofplasma lipid levels that is cholesterol triglycerides LDL-cholesterol and apolipoprotein-B decreased by 40 2361 and 61 respectively and increase in HDL-cholesteroland apolipoprotein A1 by 85 and 58 respectively [88]

426 Hypoglycemic Activity The essential oil of F vulgareexhibits potential hypoglycemic and antioxidant activityagainst streptozotocin induced diabetes in rats Essentialoil (30mgkg body weight) of F vulgare works in the

427 Antispasmodic Activity The antispasmodic activity of25 and 100mLL of alcoholic extract of Foeniculum vulgarealong with other Germanic medicinal plants namelyMelissaofficinalis Rosmarinus officinalisMentha piperitaMatricariachamomilla Carum carvi and Citrus aurantium were testedemploying the guinea pig ileum and using acetylcholine andhistamine as spasmogens An alcoholic extract of the fruits ofFoeniculum vulgare possesses antispasmodic activity whichinhibits the acetylcholine and histamine-induced guineapig ileal contractions in vitro An essential oil which isobtained from the fruits of Foeniculum vulgare 25 120583gmL and10 120583gmL respectively inhibited oxytocin and prostaglandin[72]

428 Apoptotic Activity The apoptotic activities of ethanolextracts from fruits of seven species of Apiaceae familynamely Eryngium planum Archangelica officinalis Pasti-naca sativa Heracleum sibiricum Carum carvi Foenicu-lum vulgare and Levisticum officinale against ML-1mdashhumanacute myeloblastic leukaemia J-4501mdashhuman acute Tcell leukaemia EOLmdashhuman eosinophilic leukaemia HL-60mdashhuman Caucasian promyelocytic leukaemia 1301mdashhuman T cell leukaemia lymphoblast C-8166mdashhuman Tcell leukaemia U-266B1mdashhuman myeloma WICLmdashhumanCaucasian normal B cell and H-9mdashhuman T cell wereinvestigated with the help of Trypan blue assay and AnnexinV fluos assay [86] The ethanol extract from fruit F vulgareshowed the highest mortality in Trypan blue test for J45cell linemdash4 of viable cells and for C8166 cell linemdash100of mortality However the cells of other lines showed thehighest viability HL60mdash60 EOLmdash48 and MLmdash1ndash42The normal cell line H9 and WICL showed 35 and 25of viable cells respectively C8166 cell line and J-45 cell lineshowed the highest level of the apoptotic cells detected byAnnexin V methodmdash100 and 93 respectively Howeverthe cells of two lines HL60 and EOL-1 showed the lowerlevels of apoptotic cellsmdash52 and 60 respectively Highpercentage of apoptotic cells was observed inH9 andWICLmdash76 and 93 respectively [86]

429 Human Liver Cytochrome P450 3A4 Inhibitory ActivityThirteen compounds isolated from the methanolic extract offennel have been found to possess human liver cytochromeP450 3A4 inhibitory activity Among these compounds 5-methoxypsoralen (5-MoP) showed the strongest inhibitionwith an IC50 value of 183120583m and with a mixed type ofinhibition [83]

430 Antiaging Effects Rasul and his coworker developeda base and formulation containing 4 concentrated seedextract of F vulgare This formulation shows notable antiag-ing effect with supporting experimental data related to skinmoisture and transepidermal water loss (TEWL) The basewas insignificant while the formulation showed significanteffects on skin moisture and TEWL The texture parameterenergy showed a significant increase proving that the formu-lation possesses potential antiaging effects [50]

431 Bronchodilatory Effect Ethanol extract and essential oilfrom F vulgare exhibited bronchodilatory activity on con-tracted tracheal chains of guinea pig The potassium channelopening effect of fennel may contribute on its relaxant effecton guinea pig tracheal chains [111] Moreover anethole bearsa striking resemblance to the catecholamines epinephrinenorepinephrine and dopamine This structural similarityappears to be responsible for the various sympathomimeticactivities of F vulgare such as bronchodilatory effect [71]

432 Antioxidant Activities Naturally occurring antioxi-dants can be used to protect human beings from oxidativestress damage [112] Fennel was known as excellent source ofnatural antioxidants and contributed to the daily antioxidantdiet [113]Wild fennel was found to exhibit a free radical scav-enging activity with higher content phenolic and flavonoidthan medicinal and edible fennel and the aerial parts ofthe Italian fennel populations showed the highest DPPHscavenging activity [65] Phenolic compounds of fennelincluding caffeoylquinic acid rosmarinic acid eriodictyol-7-orutinoside quercetin-3-O-galactoside and kaempferol-3-O-glucoside showed antioxidant activities [67] The volatileoil showed strong antioxidant activity in comparison withbutyrated hydroxyanisole and butylated hydroxytolueneEthanol and water extracts of fennel showed less antioxidantactivity compared with essential oil [114]

5 Environmental Application

Foeniculum vulgare that is fennel not only exhibited phar-macological activities but also revealed a few environmentalactivities These activities play a key role in the managementof nematode insect mosquitoes and some harmful larvae ofmalaria producing vector Thus the extracts of F vulgare andisolated biologically active compounds have been evaluatedfor their insecticidal repellent acaricidal larvicidal andnematicidal activity [115ndash119] A brief review on the differenttype of ecofriendly environmental activities as reported onthis plant is summarized below

51 Insecticidal Activities The fruit derived phytoconstitu-ents of F vulgare exhibited prominent insecticidal activi-ties against Sitophilus oryzae Callosobruchus chinensis andLasioderma serricorne This activity was examined usingdirect contact application and fumigation methods Thebiologically active constituents that is phenylpropenes (E)-anethole and estragole and the monoterpene (+)-fenchonewere characterized from Foeniculum fruit By using a filter

26 BioMed Research International

paper diffusion test estragole (0168mg cmminus2) caused 91mortality to S oryzae within 1 day after treatment whereas(+)-fenchone and (E)-anethole gave over 90 mortality at 2and 4 day after treatment respectively

After 2 days of treatment all test compounds (0021mg cmminus2 concentration) revealed potent insecticidal activityagainst C chinensis Whereas after 1 day of treatment (E)-anethole (0105mg cmminus2) gave 100mortality of L serricornewhereas 90 and 60 mortality at 4 day after treatment wasachieved with estragole and (+)-fenchone respectively In afumigation test the compounds were much more effectiveagainst adults of S oryzae C chinensis and L serricorne inclosed cups than in open ones indicating that the insecticidalactivity of test compounds was largely attributable to fumi-gant action As naturally occurring insect-control agents theF vulgare fruit-derived materials described could be usefulfor managing field populations of S oryzae C chinensis andL serricorne [116]

52 Acaricidal Activity Fennel oil shows significant acaricid-al activity againstDermatophagoides farinae andDermatoph-agoides pteronyssinus (+)-fenchone and p-anisaldehyde aremajor constituents of fruit oil of F vulgare P-anisaldehydewas the most toxic compound against D farinae and is muchmore effective compared with benzyl benzoate thymol andestragol [118]

53 Repellent Activity The methanolic extract of fruits ofF vulgare was spectroscopically characterized for the pres-ence of biologically active constituents called (+)-fenchoneand (E)-9-octadecenoic acid The repellent activity of theseconstituents was tested against hungry Aedes aegypti femaleswith the help of skin and patch tests and compared withthat of the commercial repellent agent called NN-diethyl-m-toluamide (DEET) and (Z)-9-octadecenoic acid In askin test with female mosquitoes (+)-fenchone and (Z)-9-octadecenoic acid (04mgcm2) exhibitedmoderate repellentactivity at 30min after treatment whereas DEET providedgt1 h of protection against adult mosquitoes at (02mgcm2)Thus (+)-Fenchone and (E)-9-octadecenoic acid are poten-tial mosquito repellent agents or lead compounds [117]

54 Larvicidal Activity Plant extracts and oils may act asalternatives to conventional pesticides for malaria vectorcontrol By considering this aspect Sedaghat et al [119] inves-tigated the larvicidal activity of essential oils of three plantsof Apiaceae family against malaria vector called Anophe-les stephensi The larvicidal activity was evaluated againstlaboratory-reared larvae by standard method of WHO TheF vulgare oil was the most effective against A stephensiwith LC(50) and LC(90) values of 2010 and 4451 ppmrespectively [119] Additionally the essential oil extracts fromleaves flowers and roots of F vulgare exhibit noticeablelarvicidal activity against fourth-instar larvae of themosquitoCulex pipiens molestus Terpineol and 18-cineole content of Fvulgare are the most effective phytoconstituent against Culexpipiens molestus bites offering complete protection for 16 and2 h respectively [120] Recently Zoubiri et al [57] reported

the larvicidal activity of essential oil of fennel seed againstCulex pipiensmosquitoThus F vulgare can serve as a naturallarvicidal agent

55 Nematicidal Activity Oka et al investigated the in vitronematicidal activity of essential oils extracted from 27 spicesand aromatic plants in pot experiments Twelve of thetwenty-seven essential oils immobilized more than 80 ofjuveniles of the root-knot nematodeMeloidogyne javanica ata concentration of 1000 120583Lliter At this concentration mostof these oils also inhibited nematode hatching Essential oilsof Carum carvi Foeniculum vulgare Mentha rotundifoliaand Mentha spicata showed the highest nematicidal activityamong the in vitro tested oils In 3-liter pot experimentsnematicidal activity of the essential oils and their componentswas confirmed at 200 and 150mgkg respectivelyThe resultssuggest that the essential oils and theirmain componentsmayserve as nematicides [115]

The long history of ethnomedicinal application with noreports of any serious side effects suggests that F vulgarecould be considered as safe Inmost toxicity experiments car-ried out on F vulgare no sign of toxicity was observed Shahand his coworker in 1991 investigated the detailed toxicityaccount of ethanolic extract of fennel fruit in experimentalmice with respect to acute and 90 days longer term toxicity[121] In experimentation Shah and his coworker observedthe general symptoms of toxicity and mortality for only 24 hin acute toxicity Whereas in another part of toxicity theystudied the effect of fennel extract on mice with 90 dayslong term treatment Acute toxicity of ethanolic extract of Fvulgarewas assessed in 35mice by using three concentrationsnamely 05 1 and 3 gkg body weight In this investigation Fvulgare exhibited no signs of toxicity and no mortality wasobserved upto the dose level 3 gkg body weight In case oflonger term toxicity ethanolic extract of F vulgare (100mgkgbody weightday) was given in drinking water of animals(30 male and 30 female mice) All external morphologicalhaematological and spermatogenic changes in addition tobody and vital organ weights were recorded The extractcaused no significant chronic mortality as compared tocontrols during this investigation The treated male micegained significant weight during chronic treatment while aloss or no significant change in weight was noticed in thefemale mice treated with the same extract The extracts didnot show spermatotoxic effects Thus Shah and his coworkerconcluded that fennel extract is safe based on both acuteandor long term toxicity studies [121] Additionally the plantextract in doses of 05 1 and 3 gkg (orally) did not causeany deaths These doses do not show any type of toxicityagainst several parameters tested namely locomotor activitybizarre reactions sensitivity to sound social interaction tailposture aggressive behaviour ataxia paralysis convulsionstremors prostration exophthalmos pupil size defecationsalivation urination pattern of respiration nasal dischargecyanosis and piloerection Exceptionally only the 3 gkg dose

showed signs of reduced locomotor activity and piloerec-tion Otherwise all other parameters were negative [108]In another experiment of acute toxicity different solventextracts namely n-hexane methylene chloride ethyl acetateand methanol extracts of F vulgare upto 55 gkg concentra-tion did not revealed any kind of toxicity in mice LD50being 675 110 692 and 15 gkg for n-hexane methylenechloride ethyl acetate and methanol extracts respectively[68] The plant extract of F vulgare was administered orallyat a dose of 100 200 400 600 800 1000 and 2000mgkgof body weight of mice Each group of animals was undervisual observation for 10 days for the external behavior ofneurological toxicity created by plant extract Even the micereceiving highest dose of F vulgare extract did not show anymortality or toxicity demonstrating the safety profile of theplant extract [89]

The acute oral 50 LD50 for anethole in rats was foundto be 2090mgkg Repeated doses of one-third the LD50 ofanethole (695mgkg) given to rat caused mild liver lesionsIt would therefore appear that in normal therapeutic dosagesanethole would have minimal hepatotoxicity When anetholewas fed to rats daily for one year as 025 of the dietno hepatic damage was seen [122] The acute oral LD50 ofessential oil in rats is 1326mgkg [76] The use of F vulgareessential oil as a remedy for control of primary dysmenorrheaincreases concern about its potential teratogenicity due toits estrogen like activity Evaluation of teratogenicity ofessential oil using limb bud mesenchymal cells showed thatthe essential oil may have toxic effect on fetal cells butthere was no evidence of teratogenicity upto concentrationof 93mgmL of culture medium [123] The overall toxicitystudies carried out on F vulgare accounts for its safety at therecommended therapeutic doses

7 Conclusions

The available scientific research on Foeniculum vulgarehas shown that it is an important medicinal plant used ina wide range of ethnomedical treatments especially forabdominal pains antiemetic aperitif arthritis cancer colicin children conjunctivitis constipation depurative diarrheadieresis emmenagogue fever flatulence gastralgia gastritisinsomnia irritable colon kidney ailments as a laxativeleucorrhoea liver pain mouth ulcer and stomachache Thisplant has been in use for a long period of time withoutany documented serious adverse effects Studies carriedout in the past and present indicate that fennel possessesdiverse health benefits and are an important constituentof food Studies have shown that various extracts offennel possess a range of pharmacological actions such asantiaging antiallergic anticolitic antihirsutism anti-inflam-matory antimicrobial and antiviral antimutagenic antino-ciceptive antipyretic antispasmodic antistress antithromb-otic anxiolytic apoptotic cardiovascular chemomodulatoryaction cytoprotection and antitumor cytotoxicity diureticestrogenic properties expectorant galactogenic gastrointes-tinal effect hepatoprotective human liver cytochrome P4503A4 inhibitory hypoglycemic hypolipidemic memory-en-hancing property nootropic and oculohypotensive activity

supporting its traditional use However the most prominentand the well studied effects are the antimicrobial andantioxidant effects of essential oil of fennel in differentexperimental models The observed health benefits may becredited to the presence of the various phytochemicals likevolatile compounds flavonoids phenolic compounds fattyacids and amino acids

Fennel also contains mineral and trace elements likealuminum barium calcium cadmium cobalt chromiumcopper ironmagnesiummanganese nickel lead strontiumand zinc [124] fat soluble vitamins such as vitamins A Eand K water soluble vitamins like ascorbic acid thiamineriboflavin niacin and pyridoxine essential amino acidslike leucine isoleucine phenylalanine and tryptophane maycontribute to the myriad health beneficial effects at least inpart

Most of the pharmacological studies were conductedusing uncharacterized crude extracts of fennel It is difficultto reproduce the results of these studies and pinpoint thebioactive compounds Hence there is a need for chemi-cal standardization and bioactivity-guided identification ofbioactive compounds Among several classes of chemicalconstituents identified in fennel volatile components of fen-nel essential oil and phenolic compounds are assumed to bethe main bioactive compounds responsible for the majorityof its pharmacological effects However the vast traditionaluse and proven pharmacological activities of fennel indicatethat an immense scope still exists for its chemical explorationFuture studies should be focused on validating the mecha-nism of action responsible for the various beneficial effectsand also on understanding which plant based compounds areresponsible for the reported effectsThe required informationwhen available will enhance our knowledge and appreciationfor the use of fennel in our daily diet Also the outcomeof such chemical studies may further expand its existingtherapeutic potential

Thus there are many areas of research related to thisplant that need to be further explored to fully recognize itsbeneficial effects for society Factors such as geographical andseasonal variation play an important role in the authentica-tion of the chemical constituents responsible for the activitywhich also can be an area of interest Thus it is incumbenton researchers to fill the huge gap of insufficient knowledgeand create awareness among pharmacologists as well as inves-tigators towards providing better medicinal value derivedfrom this plant This can be fulfilled only by generatinginterest among the research community through writing ofcritical appraisals (paper) and extending the interdisciplinaryresearch area to focused studies on Foeniculum vulgare

molds Aspergillus niger and Fusarium oxysporum Essen-tial oil of F vulgare showed significant antifungal activityagainst the food spoilage fungi Aspergillus niger and Fusar-ium oxysporum and may have important applications asfood additives The MIC values of F vulgare essential oilwere 250120583gmL for Fusarium oxysporum and 750 120583gmLfor Aspergillus niger [94] The oils extracted from F vulgareexhibit varying levels of antifungal effects on the experi-mental mycelial growth of Alternaria alternata Fusariumoxysporum and Rhizoctonia solani [95] Essential oil of Fvulgare showed appreciable antifungal activity against strainsof pathogenic fungi namely Aspergillus niger Fusariumsolani and Rhizopus solani [96] Dichloromethane extractsand essential oils from F vulgare showed antifungal activityagainst Candida albicans It could be a potential candidatefor a new antifungal agent for candidiasis and other fungal

diseases [97] In an in vitro study aqueous and alcoholicseed extracts of F vulgare exhibited inhibitory effect againstAlternaria alternata Mucor rouxii and Aspergillus flavus[98] Interestingly aqueous seed extract of F vulgare showedstrongest antifungal activity as compared to reference fungi-cidal agent that is griseofulvin [99]

All of the above mentioned studies were carried outon the crude extracts and it is difficult to pinpoint theactive antimicrobial metabolite A phenylpropanoid deriva-tive called dillapional characterized from F vulgare stem wasfound to be an antimicrobial constituent with MIC values of125 250 and 125 against Bacillus subtilis Aspergillus nigerand Cladosporium cladosporioides respectively A coumarinderivative scopoletin was also isolated as a marginallyantimicrobial agent [100] The characterization of sevendifferent types of oxygenatedmonoterpenes frommethylene

chloride crude extract of F vulgare [101] suggested thatthe crude extract containing monoterpenes could be a newmedicinal resource for antibacterial agents

A total of 78 compounds were identified from theactive antimycobacterial fraction of F vulgare with thehelp of gas chromatography-mass spectra (GC-MS) Outof these twenty compounds were tested against one sensi-tive and three MDR strains of Mycobacterium tuberculosisusing the Alamar Blue microassay Compounds that showedsome degree of antimycobacterial activity against all strainstested were the following linoleic acid (MIC 100 120583gmL)oleic acid (MIC 100 120583gmL) 13-benzenediol (MIC 100ndash200120583gmL) undecanal (MIC 50ndash200120583gmL) and 24-undecadienal (MIC 25ndash50120583gmL) 24-Undecadienal wasthe most active compound against multidrug resistant Mtuberculosis speciesThus the dietary intake of F vulgaremaylower the risk ofM tuberculosis infection [63]

Orhan et al [5] studied the antiviral activity of theessential oil of fruit sample of F vulgare along with 12other Turkish medicinal plants against the DNA virusHerpessimplex type-1 (HSV-1) and the RNA virus parainfluenzatype-3 (PI-3) Most of the oils and compounds displayedstrong antiviral effects against HSV-1 ranging between 08and 0025 120583gmL However the samples tested were lesseffective against PI-3 with results ranging between 16 and02 120583gmL Only the essential oils of Anethum graveolensFoeniculum vulgare (fully mature) Mentha piperita Menthaspicata Ocimum minutiflorum Ocimum vulgaris and Sat-ureja cuneifolia inhibited this virus significantly

All these literature findings validated the traditional usesof Foeniculum vulgare in infectious disorders like abdomi-nal pains antiemetic arthritis conjunctivitis constipationdepurative diarrhea dieresis fever flatulence gastralgia gas-tritis insomnia irritable colon mouth ulcer stomachacherespiratory disorders skin diseases and so forth There isalways a need for new antimicrobial agents due to rapiddevelopment of resistance Bioactive metabolites of F vulgaremay be a potential source for new antimicrobial agents

42 Anti-Inflammatory Activity Oral administration ofmethanol extract of F vulgare fruit to rat and mice exhibitedinhibitory effects against acute and subacute inflammatorydiseases The anti-inflammatory activity of methanol extractwas evaluated by using three screening protocols namelycarrageenan-induced paw edema arachidonic acid-inducedear edema and formaldehyde-induced arthritis Theseare widely used for testing nonsteroidal anti-inflammatorydrugs For acute inflammationmethanol extract (200mgkg)exhibits significant inhibition of paw edema (69) inducedby carrageenan injection as compared to the control groupof animals Methanol extract of F vulgare also inhibitsear-edema (70) induced by arachidonic acid in mice Thelevel of serum transaminase aspartate aminotransferase(AST) and alanine aminotransferase (ALT) significantlyincreases in the presence of methanolic extract of F vulgareon inflammation induced by formaldehyde as comparedto control group The assessment of the level of AST and

ALT provides a good and simple tool to measure the anti-inflammatory activity of the target compounds [102] Theseoverall results seem to suggest that F vulgare FME mayact on both the cyclooxygenase and lipoxygenase pathways[79]

43 Antiallergic Activity Methanolic extract of F vulgarefruit showed significant inhibitory effect on DNFB- (24-dinitrofluorobenzene-) induced delayed type hypersensitiv-ity after oral administration of 200mgkg once a day for7 days The inhibitory effect on immunologically inducedswelling suggests the possible immunosuppressive propertiesof F vulgare [79]

44 Hepatoprotective Activity Essential oil of F vulgareseeds revealed a potent hepatoprotective effect against acutehepatotoxicity produced by carbon tetrachloride in ratsOral administration of F vulgare essential oil decreases thelevels of serum aspartate aminotransferase (AST) alanineaminotransferase (ALT) alkaline phosphatase (ALP) andbilirubin as compared to the control group Ozbek et alsuggest that the constituents (d-limonene and 120573-myrcene) ofessential oil may have played a key role in the protection ofliver from CCl

4toxicity [9]

45 Anxiolytic Activity Anxiety is the unpleasant feeling offear and concern When anxiety becomes excessive it maybe considered as an anxiety disorder Anxiolytic fennel isa drug used for the treatment of anxiety and its relatedpsychological and physical symptoms Naga Kishore et al[89] investigated the anxiolytic activity of ethanolic extract ofF vulgare fruit with the help of elevated plus maze rota rodopen field test and whole board models The 100 to 200mgdose of extract per kg of body weight of animal revealedsignificant activity when compared to reference anxiolyticdrug called diazepam (1mgkg) Thus fennel extract maypossess anxiolytic activity supporting its traditional claimabout anxiolytic activity reported in 19th edition of Pharma-cology and Pharmacotherapeutics by Sathodkar Bhandarkarand Rege

46 Antistress Activity Drug and food of natural originplay a significant role in public healthcare systems and arebeing investigated as remedies for a number of stress-relateddisorders [103]Thewhole plant extract of F vulgare exhibitednotable antistress effect against stress induced by forcefulswimming of test animals The key parameters that isurinary levels of vanillyl mandelic acid (VMA) and ascorbicacid in rats were used to evaluate antistress activity Theplant extract (50 100 and 200mgkg body weight) showeda significant improvement in urinary levels of VMA (119875 lt0001) and ascorbic acid excretion levels (119875 lt 0001) in testanimals when compared to the normal basal levels in controlgroup of animalsThus the extract of entire plant of F vulgareacts as an antistress agent [13]

47 Memory-Enhancing Property There are a number ofplants whose consumption is believed to enhance memory

22 BioMed Research International

and intelligence These were usually given to children as partof their food F vulgaris an ayurvedic rasayana (mixture)possessing multiple neuropharmacological activities Theantidepressant activity of fennel has been well documentedin ethnomedicine The whole plants extract (50 100 and200mgkg) of F vulgare exhibited memory-enhancing effectagainst scopolamine-induced amnesic rats This experimentwas evaluated by conditioned avoidance response (CAR)technique The CAR of rats administered with the extractincreased gradually to 95 over 7 to 12 days The acquisition(time to achieve 95 CAR) for rats administered with theextract was dose- and time-dependent compared to controlgroup which took 12 days for acquisition The percentavoidance was always higher in the extract-treated groupsas compared to control group Animals receiving 200mgkgbody weight of the extract took ten days while groups treatedwith 100 and 50mgkg doses of the extract required elevenand twelve days respectively to reach the point of acquisitionAdministration of scopolamine produced amnesia as seenfrom reduction in the observed CAR Amnesia was greaterin the control group than in extract-treated groups How-ever continued treatment with F vulgare produced betterretention and recovery in a dose-dependent manner thanthe vehicle-treated animals Recovery from scopolamine-induced amnesia in the extract-treated groups took 3ndash5 dayswhen compared to normal (control) group which took over6 days This overall progress suggests that F vulgare extractpossesses memory-enhancing property [13]

48 Nootropic Activity Alzheimerrsquos disease is a neurode-generative disorder associated with a decline in cognitiveabilities Dementia is one of the age-related mental problemsand a characteristic symptom of Alzheimerrsquos disease Thereis some evidence in favor of use of F vulgare for the treat-ment of cognitive disorders like dementia and Alzheimerrsquosdisease Methanol extract of the whole plant of F vul-gare administered for eight successive days ameliorated theamnesic effect of scopolamine and aging-induced memorydeficits inmiceThis extract increased step-down latency andacetylcholinesterase inhibition in mice significantly Thus Fvulgaremay be employed in treatment of cognitive disorderssuch as dementia and Alzheimerrsquos disease as a nootropic andanticholinesterase agent [80]

49 Antihirsutism Activity Idiopathic hirsutism is definedas the occurrence of excessive male pattern hair growth inwomen who have a normal ovulatory menstrual cycle andnormal levels of serum androgens It may be a disorder ofperipheral androgen metabolism Traditionally Foeniculumvulgare has been used as an estrogenic agent It has beenreputed to increase milk secretion promote menstruationfacilitate birth and increase libido On considering aboveaspect Javidnia and his research team evaluated the antihir-sutism activity of ethanolic extract of F vulgare seed againstidiopathic hirsutism by preparing cream containing 1 and 2of fennel extract The efficacy of treatment with the creamcontaining 2 fennel is better than the cream containing 1fennel and these two were more potent than placebo (control

group) The mean values of hair diameter reduction were78 183 and minus05 for patients receiving the creamscontaining 1 2 and 0 (placebo) respectively [78]

410 Estrogenic Properties Since the discovery of the estrusinducing effects of some plant products in 1926 consider-able effort has been devoted towards the characterizationof phytoestrogens including flavonoids isoflavonoids chal-cones coumestans stilbenes lignans saponins and essentialoils [16] F vulgare has estrogen-like activity In male ratstotal concentration of protein was found to be significantlydecreased in testes and in vasa deferentia whereas increasedin seminal vesicles and in prostate gland On the otherhand simultaneous decrease in the activities of acid andalkaline phosphatase in all these regions (except that alka-line phosphatase was unchanged in vasa) due to the oraladministration of acetone extract of F vulgare fruit wasobserved In female rats oral administration of the extract for10 days led to vaginal cornification and oestrus cycle [8] Totalconcentration of nucleic acids and protein as well as the organweights increased in both the tissues namely mammaryglands and oviducts due to the oral administration of acetoneextract (50 150 and 250120583g100 g body wt) of F vulgare seeds[104] Fennel oil was reported to exhibit estrogenic activitypromote menstruation and alleviate the symptoms of femaleclimacteric and increase libido [71] Administration of fenneloil (25 and 50 120583gmL final concentration in the organ bath)failed to exhibit any remarkable effect in uterine contrac-tion While 10 20 and 40 120583gml concentration of fennel oilrevealed significant inhibitory effect against prostaglandinE2 Fennel oil significantly reduces the frequency of uterinecontraction induced by prostaglandin E2 Thus the extractsof F vulgare have strong estrogenic activity [76]

411 Galactogenic Activity Foeniculum vulgare has been usedformillennia to increasemilk secretion [105]Thus F vulgarebelongs to galactagogue substance Structural similarity ofits main constituent anethole to dopamine seems to beresponsible for galactogenic activityDopamine acts to inhibitthe secretion of the milk-producing hormone prolactinAnethole might influence milk secretion by competing withdopamine at the appropriate receptor sites thereby inhibitingthe antisecretory action of dopamine on prolactin [71] It wasreported that anol (demethylated anethole) causes growthof the lobule-alveolar system in the mammary glands ofimmature female rabbits and induces menstruation in miceand other experimental animals Anol also gave positiveresults in the Jadassohn nipple test a test which involvesthe measurement of changes induced in the nipples ofguinea pigs subjected to the cutaneous application of sexhormones However further research suggests that the actualpharmacologically active agents responsible for galactogenicactivity are polymers of anethole such as dianethole andphotoanethole rather than anol or anethole itself [20 76]

412 Expectorant Activity F vulgare seeds stimulate theciliary motility of the respiratory apparatus and enhance the

BioMed Research International 23

external transport of extraneous corpuscles This action sug-gests a use for fennel in treating bronchial and bronchopul-monary afflictions and in particularly polluted environments[106] The volatile oil of F vulgare stimulates the contractionof the smooth muscles of the trachea an action that couldfacilitate the expectoration of mucus bacteria and othercorpuscles extraneous to the respiratory tracts [74]

413 Anticolitic Activity Essential oil of fennel regulates themotility of smooth muscles of the intestine while at thesame time reducing intestinal gas Alone or combined withother plant medicinals Foeniculum vulgare is indicated in thetreatment of spastic gastrointestinal disturbances in someforms of chronic colitis (which resist other treatments) indyspepsias from gastrointestinal atony in dyspepsias withthe sensation of heaviness in the stomach and so forthTheaddition of fennel to preparations containing anthraquinoniccomponents reduces the occurrence of abdominal pain oftenassociated with this type of laxative [73]

414 Antinociceptive Activity Antinociceptive means anysubstance that inhibits nociception which is a physiologicalprocess underlying the sensation of pain Briefly it reducesthe sensitivity to painful stimuli The various extracts ofaerial part of F vulgare namely hexane methylene chlorideethyl acetate and methanolic extract showed remarkableantinociceptive activity against acetic acid induced writhingin mice [68] The methanolic extract of the aerial parts ofF vulgare exhibited the highest antinociceptive activity at adose level of 2000mgkg while the activity exhibited by theethyl acetate extract was at dose level 800mgkgOn the otherhand n-hexane extract (700mgkg) and methylene chlorideextract (500mgkg) exhibited similar antinociceptive activi-ties being less than peripheral antinociceptive reference drug(acetyl salicylic acid) [68]

415 Diuretic Activity A diuretic is any substance thatpromotes the production of urine Briefly it is an agentthat promotes diuresis Diuretics work by promoting theexpulsion of urine (measured as the urine volume [UV]excreted) and urinary sodium (UNa) from the body and thishelps reduce the volume of blood circulating through thecardiovascular system Caceres et al [107] performed a studyin conscious animals and administered a powdered extractof the whole plant (F vulgare) which had no effect on UVor UNa The ethanolic extract of F vulgare fruit revealedexcellent diuretic activity and proves the earlier folk claimof F vulgare which was reported in the United State ofAmerica (Table 5) The fruit extract showed statistically ahighly significant diuretic effect F vulgare induced diuresis(500mgkg dose)was comparable to that of reference diureticagent urea (960mgkg dose) in mice with a urine outputthat was almost double that of the control group Thediuresis was not associated with changes in sodium andorpotassium excretion [108] In another part of the study theauthors showed that Foeniculum vulgare had little effect onthe noradrenalin contractile responses of aortic rings thus

suggesting that it worked mainly as a diuretic and natriureticwith little effect on arterial vascular tone [77]

416 Cardiovascular Activity An aqueous extract of F vul-gare leaves possesses potential cardiovascular action Thiseffect was investigated using pentobarbital-anaesthetisedmale albino Sprague-Dawley rats [75] An intravenousadministration of the lyophilized boiled water extract ofleaves produced a significant dose-related reduction in arte-rial blood pressure without affecting the heart rate or respi-ratory rate On the other hand the nonboiled aqueous extractshowed very little hypotensive activityThe hypotensive effectof the boiling water extract appeared not to be mediated viaadrenergicmuscarinic ganglionic or serotonergic receptorshowever histamine antagonists inhibited the hypotensiveeffect in a dose-related manner [75]

417 Oculohypotensive Activity The aqueous seed extract ofF vulgare demonstrated significant oculohypotensive activityusing water loading and steroid induced glaucoma modelThis extract exhibited 1749 2116 and 2203 reduction ofintraocular pressure in normotensive rabbits at 03 06and 12 (wv) concentrations respectively A maximummean difference of 3120 was observed between vehiclestreated and extracts treated eyes in water loading experi-mental animal model while a maximum mean intraocularpressure lowering of 3129 was observed in steroid inducedmodel of glaucoma Thus the aqueous extract of F vulgarerevealed oculohypotensive activity which was found to be asgood as that of reference standard antiglaucoma drugs calledtimolol [84]

418 Antithrombotic Activity Tognolini et al [55] providedevidence of potent inhibitory activity of essential oil of F vul-gare against platelet aggregation induced byADP arachidonicacid and collagen in guinea pig plasma Similar findingswere reported by Yoshioka and Tamada [109] for aggregationof rabbit platelets by an aromatic factor of fennel oil Theessential oil and anethole (a constituent of oil) of F vulgaretested in vitro in rat aorta with or without endotheliumdisplayed comparable NO-independent vasorelaxant activityat antiplatelet concentrations It supports the safety of Fvulgare that is free from cytotoxic effects Anethole and Fvulgare did not cause cytotoxicity when incubated for 30minupto 300 120583gmL in platelet viability test This concentrationwas largely compatible with those adopted in the functionalin vitro tests In vivo both F vulgare essential oil andanethole orally administered in a subacute treatment to mice(30mgkgday for 5 days) showed significant antithrom-botic activity preventing the paralysis induced by collagen-epinephrine intravenous injection (70 and 83 protectionresp)Thus essential oil and its main component anethole ofF vulgare showed a safe antithrombotic activity in guinea pigplasma that seems due to their broad spectrum antiplateletactivity clot destabilizing effect and vasorelaxant action [55]

419 Antimutagenic Effect Essential oil of F vulgare revealednoteworthy protective effects against genotoxicity in mice

24 BioMed Research International

induced by cyclophosphamide Genotoxicity and cytotoxicitywere assessed by using mice bone marrow chromosomalaberration micronucleus and sperm abnormality assaysrespectively Oral administration of essential oil (1 and2mLkg) significantly inhibited the frequencies of aberrantmetaphases chromosomal aberrations micronuclei forma-tion and cytotoxicity in mouse bone marrow cells inducedby cyclophosphamide and also produced a significant reduc-tion of abnormal sperm and antagonized the reduction ofcyclophosphamide induced superoxide dismutase catalaseand glutathione activities and inhibited increased malondi-aldehyde content in the liver Additionally F vulgare inhibitsthe oxidative stress induced by cyclophosphamide [90]

420 Gastrointestinal Effect Theaqueous extract of F vulgareshowed remarkable antiulcerogenic effect against ethanol-induced gastric lesions in rats It was found that pretreatmentwith aqueous extract significantly reduced ethanol-inducedgastric damageThis effect of aqueous extract was highest andstatistically significant in 300mgkg group comparedwith thecontrol (119875 lt 0001) group of animal Additionally aqueousextract of F vulgare significantly reduced the whole bloodmalondialdehyde levels while significantly increased nitritenitrate ascorbic acid retinol and beta-carotene levels Thusaqueous extract of F vulgare fruit had clearly a protectiveeffect against ethanol-induced gastric mucosal lesion in rats[81]

421 Chemomodulatory Action The chemopreventive effectof different doses of test diet of Foeniculum vulgare seeds wasexamined against 712-dimethylbenz(a)anthracene- (DMBA-) induced skin papillomagenesis and benzo(a)pyrene-[B(a)P-] induced forestomach papillomagenesis at the peri-initiational level in Swiss albino mice Fennel seeds exhibita significant reduction in the skin and the fore-stomachtumor incidence and tumor multiplicity as compared tothe control group Further biochemical assays showeda significant increase in the contentactivities of phase Ienzymes especially in the case of 6 test diet A concomitantincrease in the activities of the phase II enzymes wasobserved with all the doses of test diet under study Asignificant enhancement in the activities of antioxidantenzymes was observed especially at 4 and 6 test diets offennel These findings were indicative of chemopreventivepotential of fennel against carcinogenesis This is the firstreport showing chemopreventive potential of seeds of fennelagainst carcinogenesis [85]

422 Cytoprotection and Antitumor Activity Anethole is theprincipal active component of fennel seeds which has exhib-ited anticancer activity Al-Harbi et al studied the antitumoractivity of anethole against Ehrlich ascites carcinoma inducedin a tumor model in Swiss albino mice The study revealedthat anethole increased survival time reduced tumor weightand reduced the volume and body weight of the Ehrlichascites tumour-bearing mice It also produced a significantcytotoxic effect in the Ehrlich ascites tumour cells in the pawreduced the levels of nucleic acids and malondialdehyde and

increased glutathione concentrations [110] In vitro cytopro-tection activity of methanolic extract of Foeniculum vulgarewas evaluated against normal human blood lymphocytes bymicronucleus assay and antitumor activity against B16F10melanoma cell line by Trypan blue exclusion assay for cellviability Lymphocyte culture treated with 70 methanolicextract of Foeniculum vulgare showed very less percentage ofmicronucleus that is 0006 as compared to standard drugdoxorubicin which showed 0018 micronucleus On theother hand 70methanolic extract of Foeniculum vulgare haspotent antitumor activity at the concentration of 200120583gmLThe results suggest that the Foeniculum vulgare could beconsidered as a natural resource of antitumor agents as wellas cytoprotective to normal cells [11]

423 Cytotoxicity Kaileh and his coworker investigated thecytotoxic effect of organic extracts of 24 selected Palestinianmedicinal plant species The plant selection was based onexisting ethnobotanic information and interviews with localhealers The extracts of the plants under investigation weretested for their potential antitumor (cytotoxic) effect on themurine fibrosarcoma L929sA cells and on the human breastcancer cells MDA-MB231 and MCF7 The extract from Fvulgare presented an IC (50) value at 24 h of 700 plusmn 28 and500plusmn17 120583gmL on L929sA andMCF7 cells respectivelyThenuclear transcription factor NFkappaB or NF120581B regulatesthe expression of various genes They further investigatedthe effect of nine promising plant extracts withheld fromthe first cell viability screening on NF120581B activation Thedichloromethane and methanol (1 1) extract of aerial part ofF vulgare revealed immunomodulatory NF120581B activities [82]Also Berrington and Lall investigated the in vitro cytotoxicityof acetone extracts of F vulgare and other eight medicinalplants against a noncancerous African green monkey kidney(Vero) cell line and an adenocarcinoma cervical cancer(HeLa) cell line [87]

424 Antipyretic Activity F vulgare extract showedantipyretic activity against hyperpyrexia in mice It wasinduced by SC administration of 2mL100 g of a 20aqueous suspension of brewerrsquos yeast As an antipyreticagent ethanolic extract of F vulgare fruit showed a moderateantipyretic activity that was statistically significant after 30and 90min (119875 lt 001) [108]

425 Hypolipidemic Activity The aqueous extract of F vul-gare revealed notable hypolipidemic and antiatherogenicactivity against Triton WR-1339 induced hyperlipidemiain mice Aqueous extract causes significant reduction ofplasma lipid levels that is cholesterol triglycerides LDL-cholesterol and apolipoprotein-B decreased by 40 2361 and 61 respectively and increase in HDL-cholesteroland apolipoprotein A1 by 85 and 58 respectively [88]

426 Hypoglycemic Activity The essential oil of F vulgareexhibits potential hypoglycemic and antioxidant activityagainst streptozotocin induced diabetes in rats Essentialoil (30mgkg body weight) of F vulgare works in the

427 Antispasmodic Activity The antispasmodic activity of25 and 100mLL of alcoholic extract of Foeniculum vulgarealong with other Germanic medicinal plants namelyMelissaofficinalis Rosmarinus officinalisMentha piperitaMatricariachamomilla Carum carvi and Citrus aurantium were testedemploying the guinea pig ileum and using acetylcholine andhistamine as spasmogens An alcoholic extract of the fruits ofFoeniculum vulgare possesses antispasmodic activity whichinhibits the acetylcholine and histamine-induced guineapig ileal contractions in vitro An essential oil which isobtained from the fruits of Foeniculum vulgare 25 120583gmL and10 120583gmL respectively inhibited oxytocin and prostaglandin[72]

428 Apoptotic Activity The apoptotic activities of ethanolextracts from fruits of seven species of Apiaceae familynamely Eryngium planum Archangelica officinalis Pasti-naca sativa Heracleum sibiricum Carum carvi Foenicu-lum vulgare and Levisticum officinale against ML-1mdashhumanacute myeloblastic leukaemia J-4501mdashhuman acute Tcell leukaemia EOLmdashhuman eosinophilic leukaemia HL-60mdashhuman Caucasian promyelocytic leukaemia 1301mdashhuman T cell leukaemia lymphoblast C-8166mdashhuman Tcell leukaemia U-266B1mdashhuman myeloma WICLmdashhumanCaucasian normal B cell and H-9mdashhuman T cell wereinvestigated with the help of Trypan blue assay and AnnexinV fluos assay [86] The ethanol extract from fruit F vulgareshowed the highest mortality in Trypan blue test for J45cell linemdash4 of viable cells and for C8166 cell linemdash100of mortality However the cells of other lines showed thehighest viability HL60mdash60 EOLmdash48 and MLmdash1ndash42The normal cell line H9 and WICL showed 35 and 25of viable cells respectively C8166 cell line and J-45 cell lineshowed the highest level of the apoptotic cells detected byAnnexin V methodmdash100 and 93 respectively Howeverthe cells of two lines HL60 and EOL-1 showed the lowerlevels of apoptotic cellsmdash52 and 60 respectively Highpercentage of apoptotic cells was observed inH9 andWICLmdash76 and 93 respectively [86]

429 Human Liver Cytochrome P450 3A4 Inhibitory ActivityThirteen compounds isolated from the methanolic extract offennel have been found to possess human liver cytochromeP450 3A4 inhibitory activity Among these compounds 5-methoxypsoralen (5-MoP) showed the strongest inhibitionwith an IC50 value of 183120583m and with a mixed type ofinhibition [83]

430 Antiaging Effects Rasul and his coworker developeda base and formulation containing 4 concentrated seedextract of F vulgare This formulation shows notable antiag-ing effect with supporting experimental data related to skinmoisture and transepidermal water loss (TEWL) The basewas insignificant while the formulation showed significanteffects on skin moisture and TEWL The texture parameterenergy showed a significant increase proving that the formu-lation possesses potential antiaging effects [50]

431 Bronchodilatory Effect Ethanol extract and essential oilfrom F vulgare exhibited bronchodilatory activity on con-tracted tracheal chains of guinea pig The potassium channelopening effect of fennel may contribute on its relaxant effecton guinea pig tracheal chains [111] Moreover anethole bearsa striking resemblance to the catecholamines epinephrinenorepinephrine and dopamine This structural similarityappears to be responsible for the various sympathomimeticactivities of F vulgare such as bronchodilatory effect [71]

432 Antioxidant Activities Naturally occurring antioxi-dants can be used to protect human beings from oxidativestress damage [112] Fennel was known as excellent source ofnatural antioxidants and contributed to the daily antioxidantdiet [113]Wild fennel was found to exhibit a free radical scav-enging activity with higher content phenolic and flavonoidthan medicinal and edible fennel and the aerial parts ofthe Italian fennel populations showed the highest DPPHscavenging activity [65] Phenolic compounds of fennelincluding caffeoylquinic acid rosmarinic acid eriodictyol-7-orutinoside quercetin-3-O-galactoside and kaempferol-3-O-glucoside showed antioxidant activities [67] The volatileoil showed strong antioxidant activity in comparison withbutyrated hydroxyanisole and butylated hydroxytolueneEthanol and water extracts of fennel showed less antioxidantactivity compared with essential oil [114]

5 Environmental Application

Foeniculum vulgare that is fennel not only exhibited phar-macological activities but also revealed a few environmentalactivities These activities play a key role in the managementof nematode insect mosquitoes and some harmful larvae ofmalaria producing vector Thus the extracts of F vulgare andisolated biologically active compounds have been evaluatedfor their insecticidal repellent acaricidal larvicidal andnematicidal activity [115ndash119] A brief review on the differenttype of ecofriendly environmental activities as reported onthis plant is summarized below

51 Insecticidal Activities The fruit derived phytoconstitu-ents of F vulgare exhibited prominent insecticidal activi-ties against Sitophilus oryzae Callosobruchus chinensis andLasioderma serricorne This activity was examined usingdirect contact application and fumigation methods Thebiologically active constituents that is phenylpropenes (E)-anethole and estragole and the monoterpene (+)-fenchonewere characterized from Foeniculum fruit By using a filter

26 BioMed Research International

paper diffusion test estragole (0168mg cmminus2) caused 91mortality to S oryzae within 1 day after treatment whereas(+)-fenchone and (E)-anethole gave over 90 mortality at 2and 4 day after treatment respectively

After 2 days of treatment all test compounds (0021mg cmminus2 concentration) revealed potent insecticidal activityagainst C chinensis Whereas after 1 day of treatment (E)-anethole (0105mg cmminus2) gave 100mortality of L serricornewhereas 90 and 60 mortality at 4 day after treatment wasachieved with estragole and (+)-fenchone respectively In afumigation test the compounds were much more effectiveagainst adults of S oryzae C chinensis and L serricorne inclosed cups than in open ones indicating that the insecticidalactivity of test compounds was largely attributable to fumi-gant action As naturally occurring insect-control agents theF vulgare fruit-derived materials described could be usefulfor managing field populations of S oryzae C chinensis andL serricorne [116]

52 Acaricidal Activity Fennel oil shows significant acaricid-al activity againstDermatophagoides farinae andDermatoph-agoides pteronyssinus (+)-fenchone and p-anisaldehyde aremajor constituents of fruit oil of F vulgare P-anisaldehydewas the most toxic compound against D farinae and is muchmore effective compared with benzyl benzoate thymol andestragol [118]

53 Repellent Activity The methanolic extract of fruits ofF vulgare was spectroscopically characterized for the pres-ence of biologically active constituents called (+)-fenchoneand (E)-9-octadecenoic acid The repellent activity of theseconstituents was tested against hungry Aedes aegypti femaleswith the help of skin and patch tests and compared withthat of the commercial repellent agent called NN-diethyl-m-toluamide (DEET) and (Z)-9-octadecenoic acid In askin test with female mosquitoes (+)-fenchone and (Z)-9-octadecenoic acid (04mgcm2) exhibitedmoderate repellentactivity at 30min after treatment whereas DEET providedgt1 h of protection against adult mosquitoes at (02mgcm2)Thus (+)-Fenchone and (E)-9-octadecenoic acid are poten-tial mosquito repellent agents or lead compounds [117]

54 Larvicidal Activity Plant extracts and oils may act asalternatives to conventional pesticides for malaria vectorcontrol By considering this aspect Sedaghat et al [119] inves-tigated the larvicidal activity of essential oils of three plantsof Apiaceae family against malaria vector called Anophe-les stephensi The larvicidal activity was evaluated againstlaboratory-reared larvae by standard method of WHO TheF vulgare oil was the most effective against A stephensiwith LC(50) and LC(90) values of 2010 and 4451 ppmrespectively [119] Additionally the essential oil extracts fromleaves flowers and roots of F vulgare exhibit noticeablelarvicidal activity against fourth-instar larvae of themosquitoCulex pipiens molestus Terpineol and 18-cineole content of Fvulgare are the most effective phytoconstituent against Culexpipiens molestus bites offering complete protection for 16 and2 h respectively [120] Recently Zoubiri et al [57] reported

the larvicidal activity of essential oil of fennel seed againstCulex pipiensmosquitoThus F vulgare can serve as a naturallarvicidal agent

55 Nematicidal Activity Oka et al investigated the in vitronematicidal activity of essential oils extracted from 27 spicesand aromatic plants in pot experiments Twelve of thetwenty-seven essential oils immobilized more than 80 ofjuveniles of the root-knot nematodeMeloidogyne javanica ata concentration of 1000 120583Lliter At this concentration mostof these oils also inhibited nematode hatching Essential oilsof Carum carvi Foeniculum vulgare Mentha rotundifoliaand Mentha spicata showed the highest nematicidal activityamong the in vitro tested oils In 3-liter pot experimentsnematicidal activity of the essential oils and their componentswas confirmed at 200 and 150mgkg respectivelyThe resultssuggest that the essential oils and theirmain componentsmayserve as nematicides [115]

6 Toxicity

The long history of ethnomedicinal application with noreports of any serious side effects suggests that F vulgarecould be considered as safe Inmost toxicity experiments car-ried out on F vulgare no sign of toxicity was observed Shahand his coworker in 1991 investigated the detailed toxicityaccount of ethanolic extract of fennel fruit in experimentalmice with respect to acute and 90 days longer term toxicity[121] In experimentation Shah and his coworker observedthe general symptoms of toxicity and mortality for only 24 hin acute toxicity Whereas in another part of toxicity theystudied the effect of fennel extract on mice with 90 dayslong term treatment Acute toxicity of ethanolic extract of Fvulgarewas assessed in 35mice by using three concentrationsnamely 05 1 and 3 gkg body weight In this investigation Fvulgare exhibited no signs of toxicity and no mortality wasobserved upto the dose level 3 gkg body weight In case oflonger term toxicity ethanolic extract of F vulgare (100mgkgbody weightday) was given in drinking water of animals(30 male and 30 female mice) All external morphologicalhaematological and spermatogenic changes in addition tobody and vital organ weights were recorded The extractcaused no significant chronic mortality as compared tocontrols during this investigation The treated male micegained significant weight during chronic treatment while aloss or no significant change in weight was noticed in thefemale mice treated with the same extract The extracts didnot show spermatotoxic effects Thus Shah and his coworkerconcluded that fennel extract is safe based on both acuteandor long term toxicity studies [121] Additionally the plantextract in doses of 05 1 and 3 gkg (orally) did not causeany deaths These doses do not show any type of toxicityagainst several parameters tested namely locomotor activitybizarre reactions sensitivity to sound social interaction tailposture aggressive behaviour ataxia paralysis convulsionstremors prostration exophthalmos pupil size defecationsalivation urination pattern of respiration nasal dischargecyanosis and piloerection Exceptionally only the 3 gkg dose

BioMed Research International 27

showed signs of reduced locomotor activity and piloerec-tion Otherwise all other parameters were negative [108]In another experiment of acute toxicity different solventextracts namely n-hexane methylene chloride ethyl acetateand methanol extracts of F vulgare upto 55 gkg concentra-tion did not revealed any kind of toxicity in mice LD50being 675 110 692 and 15 gkg for n-hexane methylenechloride ethyl acetate and methanol extracts respectively[68] The plant extract of F vulgare was administered orallyat a dose of 100 200 400 600 800 1000 and 2000mgkgof body weight of mice Each group of animals was undervisual observation for 10 days for the external behavior ofneurological toxicity created by plant extract Even the micereceiving highest dose of F vulgare extract did not show anymortality or toxicity demonstrating the safety profile of theplant extract [89]

The acute oral 50 LD50 for anethole in rats was foundto be 2090mgkg Repeated doses of one-third the LD50 ofanethole (695mgkg) given to rat caused mild liver lesionsIt would therefore appear that in normal therapeutic dosagesanethole would have minimal hepatotoxicity When anetholewas fed to rats daily for one year as 025 of the dietno hepatic damage was seen [122] The acute oral LD50 ofessential oil in rats is 1326mgkg [76] The use of F vulgareessential oil as a remedy for control of primary dysmenorrheaincreases concern about its potential teratogenicity due toits estrogen like activity Evaluation of teratogenicity ofessential oil using limb bud mesenchymal cells showed thatthe essential oil may have toxic effect on fetal cells butthere was no evidence of teratogenicity upto concentrationof 93mgmL of culture medium [123] The overall toxicitystudies carried out on F vulgare accounts for its safety at therecommended therapeutic doses

7 Conclusions

The available scientific research on Foeniculum vulgarehas shown that it is an important medicinal plant used ina wide range of ethnomedical treatments especially forabdominal pains antiemetic aperitif arthritis cancer colicin children conjunctivitis constipation depurative diarrheadieresis emmenagogue fever flatulence gastralgia gastritisinsomnia irritable colon kidney ailments as a laxativeleucorrhoea liver pain mouth ulcer and stomachache Thisplant has been in use for a long period of time withoutany documented serious adverse effects Studies carriedout in the past and present indicate that fennel possessesdiverse health benefits and are an important constituentof food Studies have shown that various extracts offennel possess a range of pharmacological actions such asantiaging antiallergic anticolitic antihirsutism anti-inflam-matory antimicrobial and antiviral antimutagenic antino-ciceptive antipyretic antispasmodic antistress antithromb-otic anxiolytic apoptotic cardiovascular chemomodulatoryaction cytoprotection and antitumor cytotoxicity diureticestrogenic properties expectorant galactogenic gastrointes-tinal effect hepatoprotective human liver cytochrome P4503A4 inhibitory hypoglycemic hypolipidemic memory-en-hancing property nootropic and oculohypotensive activity

supporting its traditional use However the most prominentand the well studied effects are the antimicrobial andantioxidant effects of essential oil of fennel in differentexperimental models The observed health benefits may becredited to the presence of the various phytochemicals likevolatile compounds flavonoids phenolic compounds fattyacids and amino acids

Fennel also contains mineral and trace elements likealuminum barium calcium cadmium cobalt chromiumcopper ironmagnesiummanganese nickel lead strontiumand zinc [124] fat soluble vitamins such as vitamins A Eand K water soluble vitamins like ascorbic acid thiamineriboflavin niacin and pyridoxine essential amino acidslike leucine isoleucine phenylalanine and tryptophane maycontribute to the myriad health beneficial effects at least inpart

Most of the pharmacological studies were conductedusing uncharacterized crude extracts of fennel It is difficultto reproduce the results of these studies and pinpoint thebioactive compounds Hence there is a need for chemi-cal standardization and bioactivity-guided identification ofbioactive compounds Among several classes of chemicalconstituents identified in fennel volatile components of fen-nel essential oil and phenolic compounds are assumed to bethe main bioactive compounds responsible for the majorityof its pharmacological effects However the vast traditionaluse and proven pharmacological activities of fennel indicatethat an immense scope still exists for its chemical explorationFuture studies should be focused on validating the mecha-nism of action responsible for the various beneficial effectsand also on understanding which plant based compounds areresponsible for the reported effectsThe required informationwhen available will enhance our knowledge and appreciationfor the use of fennel in our daily diet Also the outcomeof such chemical studies may further expand its existingtherapeutic potential

Thus there are many areas of research related to thisplant that need to be further explored to fully recognize itsbeneficial effects for society Factors such as geographical andseasonal variation play an important role in the authentica-tion of the chemical constituents responsible for the activitywhich also can be an area of interest Thus it is incumbenton researchers to fill the huge gap of insufficient knowledgeand create awareness among pharmacologists as well as inves-tigators towards providing better medicinal value derivedfrom this plant This can be fulfilled only by generatinginterest among the research community through writing ofcritical appraisals (paper) and extending the interdisciplinaryresearch area to focused studies on Foeniculum vulgare

chloride crude extract of F vulgare [101] suggested thatthe crude extract containing monoterpenes could be a newmedicinal resource for antibacterial agents

A total of 78 compounds were identified from theactive antimycobacterial fraction of F vulgare with thehelp of gas chromatography-mass spectra (GC-MS) Outof these twenty compounds were tested against one sensi-tive and three MDR strains of Mycobacterium tuberculosisusing the Alamar Blue microassay Compounds that showedsome degree of antimycobacterial activity against all strainstested were the following linoleic acid (MIC 100 120583gmL)oleic acid (MIC 100 120583gmL) 13-benzenediol (MIC 100ndash200120583gmL) undecanal (MIC 50ndash200120583gmL) and 24-undecadienal (MIC 25ndash50120583gmL) 24-Undecadienal wasthe most active compound against multidrug resistant Mtuberculosis speciesThus the dietary intake of F vulgaremaylower the risk ofM tuberculosis infection [63]

Orhan et al [5] studied the antiviral activity of theessential oil of fruit sample of F vulgare along with 12other Turkish medicinal plants against the DNA virusHerpessimplex type-1 (HSV-1) and the RNA virus parainfluenzatype-3 (PI-3) Most of the oils and compounds displayedstrong antiviral effects against HSV-1 ranging between 08and 0025 120583gmL However the samples tested were lesseffective against PI-3 with results ranging between 16 and02 120583gmL Only the essential oils of Anethum graveolensFoeniculum vulgare (fully mature) Mentha piperita Menthaspicata Ocimum minutiflorum Ocimum vulgaris and Sat-ureja cuneifolia inhibited this virus significantly

All these literature findings validated the traditional usesof Foeniculum vulgare in infectious disorders like abdomi-nal pains antiemetic arthritis conjunctivitis constipationdepurative diarrhea dieresis fever flatulence gastralgia gas-tritis insomnia irritable colon mouth ulcer stomachacherespiratory disorders skin diseases and so forth There isalways a need for new antimicrobial agents due to rapiddevelopment of resistance Bioactive metabolites of F vulgaremay be a potential source for new antimicrobial agents

42 Anti-Inflammatory Activity Oral administration ofmethanol extract of F vulgare fruit to rat and mice exhibitedinhibitory effects against acute and subacute inflammatorydiseases The anti-inflammatory activity of methanol extractwas evaluated by using three screening protocols namelycarrageenan-induced paw edema arachidonic acid-inducedear edema and formaldehyde-induced arthritis Theseare widely used for testing nonsteroidal anti-inflammatorydrugs For acute inflammationmethanol extract (200mgkg)exhibits significant inhibition of paw edema (69) inducedby carrageenan injection as compared to the control groupof animals Methanol extract of F vulgare also inhibitsear-edema (70) induced by arachidonic acid in mice Thelevel of serum transaminase aspartate aminotransferase(AST) and alanine aminotransferase (ALT) significantlyincreases in the presence of methanolic extract of F vulgareon inflammation induced by formaldehyde as comparedto control group The assessment of the level of AST and

ALT provides a good and simple tool to measure the anti-inflammatory activity of the target compounds [102] Theseoverall results seem to suggest that F vulgare FME mayact on both the cyclooxygenase and lipoxygenase pathways[79]

43 Antiallergic Activity Methanolic extract of F vulgarefruit showed significant inhibitory effect on DNFB- (24-dinitrofluorobenzene-) induced delayed type hypersensitiv-ity after oral administration of 200mgkg once a day for7 days The inhibitory effect on immunologically inducedswelling suggests the possible immunosuppressive propertiesof F vulgare [79]

44 Hepatoprotective Activity Essential oil of F vulgareseeds revealed a potent hepatoprotective effect against acutehepatotoxicity produced by carbon tetrachloride in ratsOral administration of F vulgare essential oil decreases thelevels of serum aspartate aminotransferase (AST) alanineaminotransferase (ALT) alkaline phosphatase (ALP) andbilirubin as compared to the control group Ozbek et alsuggest that the constituents (d-limonene and 120573-myrcene) ofessential oil may have played a key role in the protection ofliver from CCl

4toxicity [9]

45 Anxiolytic Activity Anxiety is the unpleasant feeling offear and concern When anxiety becomes excessive it maybe considered as an anxiety disorder Anxiolytic fennel isa drug used for the treatment of anxiety and its relatedpsychological and physical symptoms Naga Kishore et al[89] investigated the anxiolytic activity of ethanolic extract ofF vulgare fruit with the help of elevated plus maze rota rodopen field test and whole board models The 100 to 200mgdose of extract per kg of body weight of animal revealedsignificant activity when compared to reference anxiolyticdrug called diazepam (1mgkg) Thus fennel extract maypossess anxiolytic activity supporting its traditional claimabout anxiolytic activity reported in 19th edition of Pharma-cology and Pharmacotherapeutics by Sathodkar Bhandarkarand Rege

46 Antistress Activity Drug and food of natural originplay a significant role in public healthcare systems and arebeing investigated as remedies for a number of stress-relateddisorders [103]Thewhole plant extract of F vulgare exhibitednotable antistress effect against stress induced by forcefulswimming of test animals The key parameters that isurinary levels of vanillyl mandelic acid (VMA) and ascorbicacid in rats were used to evaluate antistress activity Theplant extract (50 100 and 200mgkg body weight) showeda significant improvement in urinary levels of VMA (119875 lt0001) and ascorbic acid excretion levels (119875 lt 0001) in testanimals when compared to the normal basal levels in controlgroup of animalsThus the extract of entire plant of F vulgareacts as an antistress agent [13]

47 Memory-Enhancing Property There are a number ofplants whose consumption is believed to enhance memory

22 BioMed Research International

and intelligence These were usually given to children as partof their food F vulgaris an ayurvedic rasayana (mixture)possessing multiple neuropharmacological activities Theantidepressant activity of fennel has been well documentedin ethnomedicine The whole plants extract (50 100 and200mgkg) of F vulgare exhibited memory-enhancing effectagainst scopolamine-induced amnesic rats This experimentwas evaluated by conditioned avoidance response (CAR)technique The CAR of rats administered with the extractincreased gradually to 95 over 7 to 12 days The acquisition(time to achieve 95 CAR) for rats administered with theextract was dose- and time-dependent compared to controlgroup which took 12 days for acquisition The percentavoidance was always higher in the extract-treated groupsas compared to control group Animals receiving 200mgkgbody weight of the extract took ten days while groups treatedwith 100 and 50mgkg doses of the extract required elevenand twelve days respectively to reach the point of acquisitionAdministration of scopolamine produced amnesia as seenfrom reduction in the observed CAR Amnesia was greaterin the control group than in extract-treated groups How-ever continued treatment with F vulgare produced betterretention and recovery in a dose-dependent manner thanthe vehicle-treated animals Recovery from scopolamine-induced amnesia in the extract-treated groups took 3ndash5 dayswhen compared to normal (control) group which took over6 days This overall progress suggests that F vulgare extractpossesses memory-enhancing property [13]

48 Nootropic Activity Alzheimerrsquos disease is a neurode-generative disorder associated with a decline in cognitiveabilities Dementia is one of the age-related mental problemsand a characteristic symptom of Alzheimerrsquos disease Thereis some evidence in favor of use of F vulgare for the treat-ment of cognitive disorders like dementia and Alzheimerrsquosdisease Methanol extract of the whole plant of F vul-gare administered for eight successive days ameliorated theamnesic effect of scopolamine and aging-induced memorydeficits inmiceThis extract increased step-down latency andacetylcholinesterase inhibition in mice significantly Thus Fvulgaremay be employed in treatment of cognitive disorderssuch as dementia and Alzheimerrsquos disease as a nootropic andanticholinesterase agent [80]

49 Antihirsutism Activity Idiopathic hirsutism is definedas the occurrence of excessive male pattern hair growth inwomen who have a normal ovulatory menstrual cycle andnormal levels of serum androgens It may be a disorder ofperipheral androgen metabolism Traditionally Foeniculumvulgare has been used as an estrogenic agent It has beenreputed to increase milk secretion promote menstruationfacilitate birth and increase libido On considering aboveaspect Javidnia and his research team evaluated the antihir-sutism activity of ethanolic extract of F vulgare seed againstidiopathic hirsutism by preparing cream containing 1 and 2of fennel extract The efficacy of treatment with the creamcontaining 2 fennel is better than the cream containing 1fennel and these two were more potent than placebo (control

group) The mean values of hair diameter reduction were78 183 and minus05 for patients receiving the creamscontaining 1 2 and 0 (placebo) respectively [78]

410 Estrogenic Properties Since the discovery of the estrusinducing effects of some plant products in 1926 consider-able effort has been devoted towards the characterizationof phytoestrogens including flavonoids isoflavonoids chal-cones coumestans stilbenes lignans saponins and essentialoils [16] F vulgare has estrogen-like activity In male ratstotal concentration of protein was found to be significantlydecreased in testes and in vasa deferentia whereas increasedin seminal vesicles and in prostate gland On the otherhand simultaneous decrease in the activities of acid andalkaline phosphatase in all these regions (except that alka-line phosphatase was unchanged in vasa) due to the oraladministration of acetone extract of F vulgare fruit wasobserved In female rats oral administration of the extract for10 days led to vaginal cornification and oestrus cycle [8] Totalconcentration of nucleic acids and protein as well as the organweights increased in both the tissues namely mammaryglands and oviducts due to the oral administration of acetoneextract (50 150 and 250120583g100 g body wt) of F vulgare seeds[104] Fennel oil was reported to exhibit estrogenic activitypromote menstruation and alleviate the symptoms of femaleclimacteric and increase libido [71] Administration of fenneloil (25 and 50 120583gmL final concentration in the organ bath)failed to exhibit any remarkable effect in uterine contrac-tion While 10 20 and 40 120583gml concentration of fennel oilrevealed significant inhibitory effect against prostaglandinE2 Fennel oil significantly reduces the frequency of uterinecontraction induced by prostaglandin E2 Thus the extractsof F vulgare have strong estrogenic activity [76]

411 Galactogenic Activity Foeniculum vulgare has been usedformillennia to increasemilk secretion [105]Thus F vulgarebelongs to galactagogue substance Structural similarity ofits main constituent anethole to dopamine seems to beresponsible for galactogenic activityDopamine acts to inhibitthe secretion of the milk-producing hormone prolactinAnethole might influence milk secretion by competing withdopamine at the appropriate receptor sites thereby inhibitingthe antisecretory action of dopamine on prolactin [71] It wasreported that anol (demethylated anethole) causes growthof the lobule-alveolar system in the mammary glands ofimmature female rabbits and induces menstruation in miceand other experimental animals Anol also gave positiveresults in the Jadassohn nipple test a test which involvesthe measurement of changes induced in the nipples ofguinea pigs subjected to the cutaneous application of sexhormones However further research suggests that the actualpharmacologically active agents responsible for galactogenicactivity are polymers of anethole such as dianethole andphotoanethole rather than anol or anethole itself [20 76]

412 Expectorant Activity F vulgare seeds stimulate theciliary motility of the respiratory apparatus and enhance the

BioMed Research International 23

external transport of extraneous corpuscles This action sug-gests a use for fennel in treating bronchial and bronchopul-monary afflictions and in particularly polluted environments[106] The volatile oil of F vulgare stimulates the contractionof the smooth muscles of the trachea an action that couldfacilitate the expectoration of mucus bacteria and othercorpuscles extraneous to the respiratory tracts [74]

413 Anticolitic Activity Essential oil of fennel regulates themotility of smooth muscles of the intestine while at thesame time reducing intestinal gas Alone or combined withother plant medicinals Foeniculum vulgare is indicated in thetreatment of spastic gastrointestinal disturbances in someforms of chronic colitis (which resist other treatments) indyspepsias from gastrointestinal atony in dyspepsias withthe sensation of heaviness in the stomach and so forthTheaddition of fennel to preparations containing anthraquinoniccomponents reduces the occurrence of abdominal pain oftenassociated with this type of laxative [73]

414 Antinociceptive Activity Antinociceptive means anysubstance that inhibits nociception which is a physiologicalprocess underlying the sensation of pain Briefly it reducesthe sensitivity to painful stimuli The various extracts ofaerial part of F vulgare namely hexane methylene chlorideethyl acetate and methanolic extract showed remarkableantinociceptive activity against acetic acid induced writhingin mice [68] The methanolic extract of the aerial parts ofF vulgare exhibited the highest antinociceptive activity at adose level of 2000mgkg while the activity exhibited by theethyl acetate extract was at dose level 800mgkgOn the otherhand n-hexane extract (700mgkg) and methylene chlorideextract (500mgkg) exhibited similar antinociceptive activi-ties being less than peripheral antinociceptive reference drug(acetyl salicylic acid) [68]

415 Diuretic Activity A diuretic is any substance thatpromotes the production of urine Briefly it is an agentthat promotes diuresis Diuretics work by promoting theexpulsion of urine (measured as the urine volume [UV]excreted) and urinary sodium (UNa) from the body and thishelps reduce the volume of blood circulating through thecardiovascular system Caceres et al [107] performed a studyin conscious animals and administered a powdered extractof the whole plant (F vulgare) which had no effect on UVor UNa The ethanolic extract of F vulgare fruit revealedexcellent diuretic activity and proves the earlier folk claimof F vulgare which was reported in the United State ofAmerica (Table 5) The fruit extract showed statistically ahighly significant diuretic effect F vulgare induced diuresis(500mgkg dose)was comparable to that of reference diureticagent urea (960mgkg dose) in mice with a urine outputthat was almost double that of the control group Thediuresis was not associated with changes in sodium andorpotassium excretion [108] In another part of the study theauthors showed that Foeniculum vulgare had little effect onthe noradrenalin contractile responses of aortic rings thus

suggesting that it worked mainly as a diuretic and natriureticwith little effect on arterial vascular tone [77]

416 Cardiovascular Activity An aqueous extract of F vul-gare leaves possesses potential cardiovascular action Thiseffect was investigated using pentobarbital-anaesthetisedmale albino Sprague-Dawley rats [75] An intravenousadministration of the lyophilized boiled water extract ofleaves produced a significant dose-related reduction in arte-rial blood pressure without affecting the heart rate or respi-ratory rate On the other hand the nonboiled aqueous extractshowed very little hypotensive activityThe hypotensive effectof the boiling water extract appeared not to be mediated viaadrenergicmuscarinic ganglionic or serotonergic receptorshowever histamine antagonists inhibited the hypotensiveeffect in a dose-related manner [75]

417 Oculohypotensive Activity The aqueous seed extract ofF vulgare demonstrated significant oculohypotensive activityusing water loading and steroid induced glaucoma modelThis extract exhibited 1749 2116 and 2203 reduction ofintraocular pressure in normotensive rabbits at 03 06and 12 (wv) concentrations respectively A maximummean difference of 3120 was observed between vehiclestreated and extracts treated eyes in water loading experi-mental animal model while a maximum mean intraocularpressure lowering of 3129 was observed in steroid inducedmodel of glaucoma Thus the aqueous extract of F vulgarerevealed oculohypotensive activity which was found to be asgood as that of reference standard antiglaucoma drugs calledtimolol [84]

418 Antithrombotic Activity Tognolini et al [55] providedevidence of potent inhibitory activity of essential oil of F vul-gare against platelet aggregation induced byADP arachidonicacid and collagen in guinea pig plasma Similar findingswere reported by Yoshioka and Tamada [109] for aggregationof rabbit platelets by an aromatic factor of fennel oil Theessential oil and anethole (a constituent of oil) of F vulgaretested in vitro in rat aorta with or without endotheliumdisplayed comparable NO-independent vasorelaxant activityat antiplatelet concentrations It supports the safety of Fvulgare that is free from cytotoxic effects Anethole and Fvulgare did not cause cytotoxicity when incubated for 30minupto 300 120583gmL in platelet viability test This concentrationwas largely compatible with those adopted in the functionalin vitro tests In vivo both F vulgare essential oil andanethole orally administered in a subacute treatment to mice(30mgkgday for 5 days) showed significant antithrom-botic activity preventing the paralysis induced by collagen-epinephrine intravenous injection (70 and 83 protectionresp)Thus essential oil and its main component anethole ofF vulgare showed a safe antithrombotic activity in guinea pigplasma that seems due to their broad spectrum antiplateletactivity clot destabilizing effect and vasorelaxant action [55]

419 Antimutagenic Effect Essential oil of F vulgare revealednoteworthy protective effects against genotoxicity in mice

24 BioMed Research International

induced by cyclophosphamide Genotoxicity and cytotoxicitywere assessed by using mice bone marrow chromosomalaberration micronucleus and sperm abnormality assaysrespectively Oral administration of essential oil (1 and2mLkg) significantly inhibited the frequencies of aberrantmetaphases chromosomal aberrations micronuclei forma-tion and cytotoxicity in mouse bone marrow cells inducedby cyclophosphamide and also produced a significant reduc-tion of abnormal sperm and antagonized the reduction ofcyclophosphamide induced superoxide dismutase catalaseand glutathione activities and inhibited increased malondi-aldehyde content in the liver Additionally F vulgare inhibitsthe oxidative stress induced by cyclophosphamide [90]

420 Gastrointestinal Effect Theaqueous extract of F vulgareshowed remarkable antiulcerogenic effect against ethanol-induced gastric lesions in rats It was found that pretreatmentwith aqueous extract significantly reduced ethanol-inducedgastric damageThis effect of aqueous extract was highest andstatistically significant in 300mgkg group comparedwith thecontrol (119875 lt 0001) group of animal Additionally aqueousextract of F vulgare significantly reduced the whole bloodmalondialdehyde levels while significantly increased nitritenitrate ascorbic acid retinol and beta-carotene levels Thusaqueous extract of F vulgare fruit had clearly a protectiveeffect against ethanol-induced gastric mucosal lesion in rats[81]

421 Chemomodulatory Action The chemopreventive effectof different doses of test diet of Foeniculum vulgare seeds wasexamined against 712-dimethylbenz(a)anthracene- (DMBA-) induced skin papillomagenesis and benzo(a)pyrene-[B(a)P-] induced forestomach papillomagenesis at the peri-initiational level in Swiss albino mice Fennel seeds exhibita significant reduction in the skin and the fore-stomachtumor incidence and tumor multiplicity as compared tothe control group Further biochemical assays showeda significant increase in the contentactivities of phase Ienzymes especially in the case of 6 test diet A concomitantincrease in the activities of the phase II enzymes wasobserved with all the doses of test diet under study Asignificant enhancement in the activities of antioxidantenzymes was observed especially at 4 and 6 test diets offennel These findings were indicative of chemopreventivepotential of fennel against carcinogenesis This is the firstreport showing chemopreventive potential of seeds of fennelagainst carcinogenesis [85]

422 Cytoprotection and Antitumor Activity Anethole is theprincipal active component of fennel seeds which has exhib-ited anticancer activity Al-Harbi et al studied the antitumoractivity of anethole against Ehrlich ascites carcinoma inducedin a tumor model in Swiss albino mice The study revealedthat anethole increased survival time reduced tumor weightand reduced the volume and body weight of the Ehrlichascites tumour-bearing mice It also produced a significantcytotoxic effect in the Ehrlich ascites tumour cells in the pawreduced the levels of nucleic acids and malondialdehyde and

increased glutathione concentrations [110] In vitro cytopro-tection activity of methanolic extract of Foeniculum vulgarewas evaluated against normal human blood lymphocytes bymicronucleus assay and antitumor activity against B16F10melanoma cell line by Trypan blue exclusion assay for cellviability Lymphocyte culture treated with 70 methanolicextract of Foeniculum vulgare showed very less percentage ofmicronucleus that is 0006 as compared to standard drugdoxorubicin which showed 0018 micronucleus On theother hand 70methanolic extract of Foeniculum vulgare haspotent antitumor activity at the concentration of 200120583gmLThe results suggest that the Foeniculum vulgare could beconsidered as a natural resource of antitumor agents as wellas cytoprotective to normal cells [11]

423 Cytotoxicity Kaileh and his coworker investigated thecytotoxic effect of organic extracts of 24 selected Palestinianmedicinal plant species The plant selection was based onexisting ethnobotanic information and interviews with localhealers The extracts of the plants under investigation weretested for their potential antitumor (cytotoxic) effect on themurine fibrosarcoma L929sA cells and on the human breastcancer cells MDA-MB231 and MCF7 The extract from Fvulgare presented an IC (50) value at 24 h of 700 plusmn 28 and500plusmn17 120583gmL on L929sA andMCF7 cells respectivelyThenuclear transcription factor NFkappaB or NF120581B regulatesthe expression of various genes They further investigatedthe effect of nine promising plant extracts withheld fromthe first cell viability screening on NF120581B activation Thedichloromethane and methanol (1 1) extract of aerial part ofF vulgare revealed immunomodulatory NF120581B activities [82]Also Berrington and Lall investigated the in vitro cytotoxicityof acetone extracts of F vulgare and other eight medicinalplants against a noncancerous African green monkey kidney(Vero) cell line and an adenocarcinoma cervical cancer(HeLa) cell line [87]

424 Antipyretic Activity F vulgare extract showedantipyretic activity against hyperpyrexia in mice It wasinduced by SC administration of 2mL100 g of a 20aqueous suspension of brewerrsquos yeast As an antipyreticagent ethanolic extract of F vulgare fruit showed a moderateantipyretic activity that was statistically significant after 30and 90min (119875 lt 001) [108]

425 Hypolipidemic Activity The aqueous extract of F vul-gare revealed notable hypolipidemic and antiatherogenicactivity against Triton WR-1339 induced hyperlipidemiain mice Aqueous extract causes significant reduction ofplasma lipid levels that is cholesterol triglycerides LDL-cholesterol and apolipoprotein-B decreased by 40 2361 and 61 respectively and increase in HDL-cholesteroland apolipoprotein A1 by 85 and 58 respectively [88]

426 Hypoglycemic Activity The essential oil of F vulgareexhibits potential hypoglycemic and antioxidant activityagainst streptozotocin induced diabetes in rats Essentialoil (30mgkg body weight) of F vulgare works in the

BioMed Research International 25

correction of hyperglycemia from 1625 plusmn 319mgdL to8197 plusmn 197mgdL with 119875 lt 005 and the activity of serumglutathione peroxidase from 5972 plusmn 278Ug Hb to 9960 plusmn638Ug Hb with 119875 lt 005 Also essential oil of fennelimproves the pathological changes noticed in their kidneyand pancreas as compared with the control group of animalThis can prove its effect as antidiabetic in folk Medicine Thismakes the possibility of its inclusion in antidiabetic drugindustry [12]

427 Antispasmodic Activity The antispasmodic activity of25 and 100mLL of alcoholic extract of Foeniculum vulgarealong with other Germanic medicinal plants namelyMelissaofficinalis Rosmarinus officinalisMentha piperitaMatricariachamomilla Carum carvi and Citrus aurantium were testedemploying the guinea pig ileum and using acetylcholine andhistamine as spasmogens An alcoholic extract of the fruits ofFoeniculum vulgare possesses antispasmodic activity whichinhibits the acetylcholine and histamine-induced guineapig ileal contractions in vitro An essential oil which isobtained from the fruits of Foeniculum vulgare 25 120583gmL and10 120583gmL respectively inhibited oxytocin and prostaglandin[72]

428 Apoptotic Activity The apoptotic activities of ethanolextracts from fruits of seven species of Apiaceae familynamely Eryngium planum Archangelica officinalis Pasti-naca sativa Heracleum sibiricum Carum carvi Foenicu-lum vulgare and Levisticum officinale against ML-1mdashhumanacute myeloblastic leukaemia J-4501mdashhuman acute Tcell leukaemia EOLmdashhuman eosinophilic leukaemia HL-60mdashhuman Caucasian promyelocytic leukaemia 1301mdashhuman T cell leukaemia lymphoblast C-8166mdashhuman Tcell leukaemia U-266B1mdashhuman myeloma WICLmdashhumanCaucasian normal B cell and H-9mdashhuman T cell wereinvestigated with the help of Trypan blue assay and AnnexinV fluos assay [86] The ethanol extract from fruit F vulgareshowed the highest mortality in Trypan blue test for J45cell linemdash4 of viable cells and for C8166 cell linemdash100of mortality However the cells of other lines showed thehighest viability HL60mdash60 EOLmdash48 and MLmdash1ndash42The normal cell line H9 and WICL showed 35 and 25of viable cells respectively C8166 cell line and J-45 cell lineshowed the highest level of the apoptotic cells detected byAnnexin V methodmdash100 and 93 respectively Howeverthe cells of two lines HL60 and EOL-1 showed the lowerlevels of apoptotic cellsmdash52 and 60 respectively Highpercentage of apoptotic cells was observed inH9 andWICLmdash76 and 93 respectively [86]

429 Human Liver Cytochrome P450 3A4 Inhibitory ActivityThirteen compounds isolated from the methanolic extract offennel have been found to possess human liver cytochromeP450 3A4 inhibitory activity Among these compounds 5-methoxypsoralen (5-MoP) showed the strongest inhibitionwith an IC50 value of 183120583m and with a mixed type ofinhibition [83]

430 Antiaging Effects Rasul and his coworker developeda base and formulation containing 4 concentrated seedextract of F vulgare This formulation shows notable antiag-ing effect with supporting experimental data related to skinmoisture and transepidermal water loss (TEWL) The basewas insignificant while the formulation showed significanteffects on skin moisture and TEWL The texture parameterenergy showed a significant increase proving that the formu-lation possesses potential antiaging effects [50]

431 Bronchodilatory Effect Ethanol extract and essential oilfrom F vulgare exhibited bronchodilatory activity on con-tracted tracheal chains of guinea pig The potassium channelopening effect of fennel may contribute on its relaxant effecton guinea pig tracheal chains [111] Moreover anethole bearsa striking resemblance to the catecholamines epinephrinenorepinephrine and dopamine This structural similarityappears to be responsible for the various sympathomimeticactivities of F vulgare such as bronchodilatory effect [71]

432 Antioxidant Activities Naturally occurring antioxi-dants can be used to protect human beings from oxidativestress damage [112] Fennel was known as excellent source ofnatural antioxidants and contributed to the daily antioxidantdiet [113]Wild fennel was found to exhibit a free radical scav-enging activity with higher content phenolic and flavonoidthan medicinal and edible fennel and the aerial parts ofthe Italian fennel populations showed the highest DPPHscavenging activity [65] Phenolic compounds of fennelincluding caffeoylquinic acid rosmarinic acid eriodictyol-7-orutinoside quercetin-3-O-galactoside and kaempferol-3-O-glucoside showed antioxidant activities [67] The volatileoil showed strong antioxidant activity in comparison withbutyrated hydroxyanisole and butylated hydroxytolueneEthanol and water extracts of fennel showed less antioxidantactivity compared with essential oil [114]

5 Environmental Application

Foeniculum vulgare that is fennel not only exhibited phar-macological activities but also revealed a few environmentalactivities These activities play a key role in the managementof nematode insect mosquitoes and some harmful larvae ofmalaria producing vector Thus the extracts of F vulgare andisolated biologically active compounds have been evaluatedfor their insecticidal repellent acaricidal larvicidal andnematicidal activity [115ndash119] A brief review on the differenttype of ecofriendly environmental activities as reported onthis plant is summarized below

51 Insecticidal Activities The fruit derived phytoconstitu-ents of F vulgare exhibited prominent insecticidal activi-ties against Sitophilus oryzae Callosobruchus chinensis andLasioderma serricorne This activity was examined usingdirect contact application and fumigation methods Thebiologically active constituents that is phenylpropenes (E)-anethole and estragole and the monoterpene (+)-fenchonewere characterized from Foeniculum fruit By using a filter

26 BioMed Research International

paper diffusion test estragole (0168mg cmminus2) caused 91mortality to S oryzae within 1 day after treatment whereas(+)-fenchone and (E)-anethole gave over 90 mortality at 2and 4 day after treatment respectively

After 2 days of treatment all test compounds (0021mg cmminus2 concentration) revealed potent insecticidal activityagainst C chinensis Whereas after 1 day of treatment (E)-anethole (0105mg cmminus2) gave 100mortality of L serricornewhereas 90 and 60 mortality at 4 day after treatment wasachieved with estragole and (+)-fenchone respectively In afumigation test the compounds were much more effectiveagainst adults of S oryzae C chinensis and L serricorne inclosed cups than in open ones indicating that the insecticidalactivity of test compounds was largely attributable to fumi-gant action As naturally occurring insect-control agents theF vulgare fruit-derived materials described could be usefulfor managing field populations of S oryzae C chinensis andL serricorne [116]

52 Acaricidal Activity Fennel oil shows significant acaricid-al activity againstDermatophagoides farinae andDermatoph-agoides pteronyssinus (+)-fenchone and p-anisaldehyde aremajor constituents of fruit oil of F vulgare P-anisaldehydewas the most toxic compound against D farinae and is muchmore effective compared with benzyl benzoate thymol andestragol [118]

53 Repellent Activity The methanolic extract of fruits ofF vulgare was spectroscopically characterized for the pres-ence of biologically active constituents called (+)-fenchoneand (E)-9-octadecenoic acid The repellent activity of theseconstituents was tested against hungry Aedes aegypti femaleswith the help of skin and patch tests and compared withthat of the commercial repellent agent called NN-diethyl-m-toluamide (DEET) and (Z)-9-octadecenoic acid In askin test with female mosquitoes (+)-fenchone and (Z)-9-octadecenoic acid (04mgcm2) exhibitedmoderate repellentactivity at 30min after treatment whereas DEET providedgt1 h of protection against adult mosquitoes at (02mgcm2)Thus (+)-Fenchone and (E)-9-octadecenoic acid are poten-tial mosquito repellent agents or lead compounds [117]

54 Larvicidal Activity Plant extracts and oils may act asalternatives to conventional pesticides for malaria vectorcontrol By considering this aspect Sedaghat et al [119] inves-tigated the larvicidal activity of essential oils of three plantsof Apiaceae family against malaria vector called Anophe-les stephensi The larvicidal activity was evaluated againstlaboratory-reared larvae by standard method of WHO TheF vulgare oil was the most effective against A stephensiwith LC(50) and LC(90) values of 2010 and 4451 ppmrespectively [119] Additionally the essential oil extracts fromleaves flowers and roots of F vulgare exhibit noticeablelarvicidal activity against fourth-instar larvae of themosquitoCulex pipiens molestus Terpineol and 18-cineole content of Fvulgare are the most effective phytoconstituent against Culexpipiens molestus bites offering complete protection for 16 and2 h respectively [120] Recently Zoubiri et al [57] reported

the larvicidal activity of essential oil of fennel seed againstCulex pipiensmosquitoThus F vulgare can serve as a naturallarvicidal agent

55 Nematicidal Activity Oka et al investigated the in vitronematicidal activity of essential oils extracted from 27 spicesand aromatic plants in pot experiments Twelve of thetwenty-seven essential oils immobilized more than 80 ofjuveniles of the root-knot nematodeMeloidogyne javanica ata concentration of 1000 120583Lliter At this concentration mostof these oils also inhibited nematode hatching Essential oilsof Carum carvi Foeniculum vulgare Mentha rotundifoliaand Mentha spicata showed the highest nematicidal activityamong the in vitro tested oils In 3-liter pot experimentsnematicidal activity of the essential oils and their componentswas confirmed at 200 and 150mgkg respectivelyThe resultssuggest that the essential oils and theirmain componentsmayserve as nematicides [115]

6 Toxicity

The long history of ethnomedicinal application with noreports of any serious side effects suggests that F vulgarecould be considered as safe Inmost toxicity experiments car-ried out on F vulgare no sign of toxicity was observed Shahand his coworker in 1991 investigated the detailed toxicityaccount of ethanolic extract of fennel fruit in experimentalmice with respect to acute and 90 days longer term toxicity[121] In experimentation Shah and his coworker observedthe general symptoms of toxicity and mortality for only 24 hin acute toxicity Whereas in another part of toxicity theystudied the effect of fennel extract on mice with 90 dayslong term treatment Acute toxicity of ethanolic extract of Fvulgarewas assessed in 35mice by using three concentrationsnamely 05 1 and 3 gkg body weight In this investigation Fvulgare exhibited no signs of toxicity and no mortality wasobserved upto the dose level 3 gkg body weight In case oflonger term toxicity ethanolic extract of F vulgare (100mgkgbody weightday) was given in drinking water of animals(30 male and 30 female mice) All external morphologicalhaematological and spermatogenic changes in addition tobody and vital organ weights were recorded The extractcaused no significant chronic mortality as compared tocontrols during this investigation The treated male micegained significant weight during chronic treatment while aloss or no significant change in weight was noticed in thefemale mice treated with the same extract The extracts didnot show spermatotoxic effects Thus Shah and his coworkerconcluded that fennel extract is safe based on both acuteandor long term toxicity studies [121] Additionally the plantextract in doses of 05 1 and 3 gkg (orally) did not causeany deaths These doses do not show any type of toxicityagainst several parameters tested namely locomotor activitybizarre reactions sensitivity to sound social interaction tailposture aggressive behaviour ataxia paralysis convulsionstremors prostration exophthalmos pupil size defecationsalivation urination pattern of respiration nasal dischargecyanosis and piloerection Exceptionally only the 3 gkg dose

BioMed Research International 27

showed signs of reduced locomotor activity and piloerec-tion Otherwise all other parameters were negative [108]In another experiment of acute toxicity different solventextracts namely n-hexane methylene chloride ethyl acetateand methanol extracts of F vulgare upto 55 gkg concentra-tion did not revealed any kind of toxicity in mice LD50being 675 110 692 and 15 gkg for n-hexane methylenechloride ethyl acetate and methanol extracts respectively[68] The plant extract of F vulgare was administered orallyat a dose of 100 200 400 600 800 1000 and 2000mgkgof body weight of mice Each group of animals was undervisual observation for 10 days for the external behavior ofneurological toxicity created by plant extract Even the micereceiving highest dose of F vulgare extract did not show anymortality or toxicity demonstrating the safety profile of theplant extract [89]

The acute oral 50 LD50 for anethole in rats was foundto be 2090mgkg Repeated doses of one-third the LD50 ofanethole (695mgkg) given to rat caused mild liver lesionsIt would therefore appear that in normal therapeutic dosagesanethole would have minimal hepatotoxicity When anetholewas fed to rats daily for one year as 025 of the dietno hepatic damage was seen [122] The acute oral LD50 ofessential oil in rats is 1326mgkg [76] The use of F vulgareessential oil as a remedy for control of primary dysmenorrheaincreases concern about its potential teratogenicity due toits estrogen like activity Evaluation of teratogenicity ofessential oil using limb bud mesenchymal cells showed thatthe essential oil may have toxic effect on fetal cells butthere was no evidence of teratogenicity upto concentrationof 93mgmL of culture medium [123] The overall toxicitystudies carried out on F vulgare accounts for its safety at therecommended therapeutic doses

7 Conclusions

The available scientific research on Foeniculum vulgarehas shown that it is an important medicinal plant used ina wide range of ethnomedical treatments especially forabdominal pains antiemetic aperitif arthritis cancer colicin children conjunctivitis constipation depurative diarrheadieresis emmenagogue fever flatulence gastralgia gastritisinsomnia irritable colon kidney ailments as a laxativeleucorrhoea liver pain mouth ulcer and stomachache Thisplant has been in use for a long period of time withoutany documented serious adverse effects Studies carriedout in the past and present indicate that fennel possessesdiverse health benefits and are an important constituentof food Studies have shown that various extracts offennel possess a range of pharmacological actions such asantiaging antiallergic anticolitic antihirsutism anti-inflam-matory antimicrobial and antiviral antimutagenic antino-ciceptive antipyretic antispasmodic antistress antithromb-otic anxiolytic apoptotic cardiovascular chemomodulatoryaction cytoprotection and antitumor cytotoxicity diureticestrogenic properties expectorant galactogenic gastrointes-tinal effect hepatoprotective human liver cytochrome P4503A4 inhibitory hypoglycemic hypolipidemic memory-en-hancing property nootropic and oculohypotensive activity

supporting its traditional use However the most prominentand the well studied effects are the antimicrobial andantioxidant effects of essential oil of fennel in differentexperimental models The observed health benefits may becredited to the presence of the various phytochemicals likevolatile compounds flavonoids phenolic compounds fattyacids and amino acids

Fennel also contains mineral and trace elements likealuminum barium calcium cadmium cobalt chromiumcopper ironmagnesiummanganese nickel lead strontiumand zinc [124] fat soluble vitamins such as vitamins A Eand K water soluble vitamins like ascorbic acid thiamineriboflavin niacin and pyridoxine essential amino acidslike leucine isoleucine phenylalanine and tryptophane maycontribute to the myriad health beneficial effects at least inpart

Most of the pharmacological studies were conductedusing uncharacterized crude extracts of fennel It is difficultto reproduce the results of these studies and pinpoint thebioactive compounds Hence there is a need for chemi-cal standardization and bioactivity-guided identification ofbioactive compounds Among several classes of chemicalconstituents identified in fennel volatile components of fen-nel essential oil and phenolic compounds are assumed to bethe main bioactive compounds responsible for the majorityof its pharmacological effects However the vast traditionaluse and proven pharmacological activities of fennel indicatethat an immense scope still exists for its chemical explorationFuture studies should be focused on validating the mecha-nism of action responsible for the various beneficial effectsand also on understanding which plant based compounds areresponsible for the reported effectsThe required informationwhen available will enhance our knowledge and appreciationfor the use of fennel in our daily diet Also the outcomeof such chemical studies may further expand its existingtherapeutic potential

Thus there are many areas of research related to thisplant that need to be further explored to fully recognize itsbeneficial effects for society Factors such as geographical andseasonal variation play an important role in the authentica-tion of the chemical constituents responsible for the activitywhich also can be an area of interest Thus it is incumbenton researchers to fill the huge gap of insufficient knowledgeand create awareness among pharmacologists as well as inves-tigators towards providing better medicinal value derivedfrom this plant This can be fulfilled only by generatinginterest among the research community through writing ofcritical appraisals (paper) and extending the interdisciplinaryresearch area to focused studies on Foeniculum vulgare
