metabolisms disperse evil heat from superficies sooth theliver and promote yang and qi [1]Radix Bupleuriwas initiallyrecorded in Shennong Bencao Jing a famous monograph oftraditional Chinese medicine written in China in 200 AD[17] According to a record of traditional Chinese medicinedated 2000 years ago Radix Bupleuri had mainly been usedfor the treatment of mouth-bitterness throat-drying andeyes-dazzling In other monographs of Materia Medica suchas Jin Kui Yao Lue Kaibao Bencao Bencao Gangmu andXinbian Bencao this plant was described to be used for thetreatment of common cold with fever influenza hepatitismalaria menoxenia and hyperlipidemia [18] CurrentlyRadix Bupleuri exerts other pharmacological effects suchas balancing different organs and energies within the bodystrengthening the action of the digestive tract improving liverand circulatory system function and relieving liver tension[19] Therefore it is also used as a popular tonic herb inChina In Korea and Japan this plant is commonly used forthe treatment of fever pain and inflammation associatedwith influenza and the common cold [20] In addition thisplant is also used as analgesics in the treatment of distendingpain in the hypochondriac region of the chest and againstamenorrhoea

Radix Bupleuri is combined with other herbs in manyclassical formulas to improve clinical effect Xiaoyaosan(XYS) a well-known formula for relieving depression isoriginated from the book of ldquoTaiping Huimin Heji Jufangrdquo inSong Dynasty (960ndash1279 AD) consisting of Radix BupleuriRadix Angelicae Sinensis Radix Paeoniae Alba RhizomaAtractylodis Macrocephalae Poria Radix GlycyrrhizaeHerbaMenthae and Rhizoma Zingiberis Recens XYS exerts var-ious pharmacological effects including soothing the liverand improving the circulation of qi to relieve depressionFurthermore it has been commonly recognized as a safe andeffective prescription in the treatment of depressive disorder[21ndash23] The 2015 edition of the Chinese Pharmacopoeialists 97 Chinese patent medicines containing Radix Bupleuriand the compatible herbs that are more frequently describedincludeRadixGlycyrrhizaeRhizomaZingiberis RecensRadixScutellariae and Panax ginseng Table 1 lists subsets of theChinese patent drugs containing Radix Bupleuri in differentformulations Although Radix Bupleuri has been used to treatcertain diseases in ethnomedicines for thousands of yearsthis herbal medicine should be comprehensively understoodand recent information should be obtained for its clinical use

3 Botanical Characterization and Distribution

According to the Chinese pharmacopoeia Radix Bupleuri isderived from the dried roots of Bupleurum chinense DC andBupleurum scorzonerifolium Willd (Figure 1) The former isknown as ldquoBeichaihurdquo (Northern Chinese Thorowax Root)and the latter is known as ldquoNanchaihurdquo (Southern ChineseThorowax Root) due to the difference of the origin anddescription The drug is collected in spring or autumnremoved from the aerial part and soil and dried

Beichaihu As a herbaceous perennial plant Bupleurum chi-nenseDC grows to the height of 50ndash85 cm Its root is conical

taupe and approximately 6ndash20 cm in length Its stems areerect tufted and apex branched The leaves are alternate theleaf blades are broadly linear-lanceolate 4ndash7 times 06ndash08 cm insize the apex is acuminate Compound umbels are axillaryand terminal approximately 1ndash4 cm in length the bracts are0 or 2-3 linear the petals are 5 and bright yellow The fruitsare oblong brown and approximately 3mm in length Theyblossom from July to September and fruit from August toOctober This plant is widely cultivated in China Japan andKorea Moreover it grows in grasslands stream banks sunnyslopes and roadsides and other locations with altitudes of100ndash2700m [24]

Nanchaihu Bupleurum scorzonerifolium Willd is a herba-ceous perennial plant and approximately 30ndash60 cm high Itsroot is flexuose reddish brown and approximately 4ndash10 cmin length Its stems are 1ndash3 usually glabrous and apexbranchedThe leaf blades are linear or linear-lanceolate 6ndash16times 02ndash07 cm in size the apex is acuminate Compoundumbels are axillary and terminal the bracts are 1ndash3 thepetals are 5 and yellow The fruits are ellipsoid dark brownapproximately 2-3mm in length They blossom from Julyto August and fruit from August to October This plant isalso widely cultivated in East Asian countries such as ChinaJapan and Korea It grows in shrub forest margins sunnymountain slopes dry grasslands and other locations withaltitudes of 200ndash3000m [24]

There were approximately 36 Bupleurum species andvarieties in different districts and markets due to the slightlydifferent morphologic appearance of Bupleurum plantsincluding B longiradiatum Turcz with toxic ingredients andB hamiltonii Balak with very little active constituents [2526] Inevitably this situation will compromise the values ofRadix Bupleuri and even imperil the safety of the consumersUntil now several techniques have been developed to identifyand distinguish them including TLC [27] HPLC [28ndash30]HPLC-ELSD [31 32] HPLC-MS [33 34] UPLC-MS [35] andcapillary electrochromatography [36] Among thesemethodsmentioned above HPLC-ELSD is the most commonly usedanalytical method for evaluating the quality and authenticityof Radix Bupleuri The total amounts of saikosaponins a andd are used as the indicator compounds to characterize thequality of this plant with minimum contents of 03 in thePharmacopoeia of Peoplersquos Republic of China

4 Chemical Constituents

In the past few decades approximately 74 compounds havebeen isolated from Radix Bupleuri including essential oilstriterpenoid saponins polyacetylenes flavonoids lignansfatty acids and sterols Triterpenoid saponins flavonoidsand essential oil which possess multiple pharmacologicalactivities are considered as the main active ingredients ofRadix Bupleuri Their structures are shown in (Table 2)(Figures 2ndash6)

Several Chinese medicine preparations containing RadixBupleuri also have been traditionally used in the treatmentof tumors and cancer The water extracts of ldquoLong DanXie Gan Wanrdquo exerted a significant growth inhibitory effectin HL60 and HT29 cancer cell lines indicating that thisformulation may possess some chemotherapeutic potential[83] Treatment with ldquoxiao-chai-hu decoctionrdquo exhibited asignificantly lower incidence of hepatocellular carcinoma andreductions in cancer pain and tumor size The underlyingmechanismof the antitumor activities is based on stimulationof the reticuloendothelial system (RES) and is closely relatedof TNF production [84ndash86]

53 Antiviral Effects Wen et al reported that the acetoneextract of Radix Bupleuri possessed a significant antiviruseffect on acute respiratory tract infections with H1N1 virusinfection and suppressed influenzaAvirus-inducedRANTESsecretion in H1N1-infected A549 cells at a concentration of

100 and 200120583gml suggesting that Radix Bupleuri might bebeneficial for the treatment of chronic inflammatory condi-tions followed by viral infection [10] SSc has been reportedto show effective anti-HBV activity through inhibiting DNAexpression of HBsAg HBeAg and HBV [81] Treatmentwith ldquoxiao-chai-hu decoctionrdquo (20120583gml 3 days 20120583gml6 days) could inhibit the production of HBV (119875 lt 00001)and the expression of HBeAg Moreover crude saponinsof Bupleurum chinense DC could inhibit the replication ofHBV (119875 lt 00001) [87] Similarly in another study Yinet al showed that SSd isolated from the MeOH extract ofBupleurum chinense DC exhibited significant bioactivity ininhibitingDNA replication ofHBV [88]The antiviral activityof saikosaponins (a b2 c and d) and their mode of actinwere examined The results showed that all saikosaponinsexerted antiviral activity on human coronavirus-229E atconcentrations of 025ndash25120583m and the strongest activity wasobserved for saikosaponin b2 with an IC50 of 17 120583m Thismechanism might involve interference in the early stage ofviral replication such as absorption and penetration of thevirus [89]

value was 60Mm [93] Saikosaponins isolated from RadixBupleuri have been reported to exhibit antibacterial activityparticularly against Pseudomonas aeruginosa and Listeriamonocytogenes The protective effect was attributed to theimmunomodulatory action on macrophages [94] ldquoChaihuinjectionrdquo has also been tested for possible antimicrobialactivity in vitroThe results demonstrated thatmild inhibitionof Staphylococcus aureus was observed but no effects wereobserved against Staphylococcus albusNeisseria gonorrhoeaeDiplococcus pneumoniae haemolytic Streptococcus or Pseu-domonas aeruginosa [95]

56 Hepatoprotective Effects The liver protective effectsagainst CCl4 induced liver injury were investigated aftertreatment ofmicewith raw and vinegar-bakedRadix Bupleuri(5 gkgday) for 14 days The results showed that both rawand processed Radix Bupleuri showed liver protective effectsagainst CCl4 induced liver injury and the vinegar-bakedRadix Bupleuri exerted better effects than that of raw RadixBupleuri [96] Pretreated with saikosaponins especially SSaor SSd showed remarkable inhibition of D-galactosamine-induced hepatic injury through decreasing the activity ofglucose-6-phosphatase and NADPH-cytochrome C reduc-tase and increasing 51015840-nucleotidase activity [97] Similarlybupleurosides III VI IX and XIII and saikosaponin b3isolated from Bupleurum scorzonerifolium Willd were alsofound to exhibit protective effect on the D-galactosamine-induced cytotoxicity in primary cultured rat hepatocytes[98] Further studies also demonstrated that the protectiveeffects of saikosaponins isolated from Bupleurum chinenseDC could prevent hepatocyte injury through regulatingintracellular calcium levels [99] In a rat model with CCl4induced acute hepatic injury the hepatic enzyme levels (GOTGPT and ALP) and the lipid peroxidation in the liver weresignificantly reduced by the administration of SSd [100]Additionally SSd significantly reduced collagen I depositionand alanine aminotransferase level on liver fibrosis rats anddecreased the concentration of transforming growth factor1205731 (TGF-1205731) Moreover SSd was able to alleviate hepatocyteinjury from oxidative stressThe effect of SSd on liver fibrosismay be related to its ability to reduce lipid peroxidation [101]

57 Immunomodulatory Effects Yamakage et al determinedthe effects of Radix Bupleuri on spontaneous lymphaticvessel activity The results indicated that Radix Bupleurisignificantly increased the amplitude of spontaneous activityof lymphatic vessels in a concentration-dependent mannerand the mechanisms of this effect seem to be independent ofendothelial function [102] Eugenin (46) and saikochrome A(47) isolated from the MeOH extracts from Bupleurum scor-zonerifolium possessed immunosuppressive effect on humanperipheral blood T cells via inhibiting CD28-costimulatedactivation [62] SSd (10mg intraperitoneally) significantlyactivated peritoneal macrophages in terms of enhancementof phagocytic activity increased level of cellular lysosomalenzyme and suppressed the response of plaque-forming cellsto heterologous erythrocytes by stimulating T and B cells ina dose-dependent manner [103] Moreover SSd modulated

lymphocyte activity through suppressing the T cell responseand increasing the B cell response to different mitogensand the interleukin- (IL-) 2IL-4 production through areceptor-bypassed pathway [41 104 105] In another exper-iment Wong et al found that SSd was shown to inhibitOKT3CD28-costimulated human T cell proliferation andPMA PMAionomycin and Con A-induced mouse T cellactivation in vitro The underlying mechanisms involveddownregulation of NF-kB signaling by suppression of IKKand Akt activities [106]

58 Autophagic Effect Autophagy is a complex processin cells which occurs through the formation of double-membrane vesicles (autophagosomes) which are engulfedby cytoplasmic molecules Then the autophagosome fuseswith the lysosomes leading to degradation of long-livedproteins aggregated proteins and damaged organelles [107ndash109] Moreover autophagy might be triggered by hypoxianutritional deprivation radiation chemical drugs and otherstimulants [110] Autophagy contributes to the pathogenesisof diverse diseases such as neuronal degeneration inflamma-tory bowel disease aging and cancer [111 112] In the previousstudy Law et al demonstrated that the protective pharma-cological effects of Radix Bupleuri might be attributed to itsautophagy inductionThe autophagic effect of Radix Bupleuriplayed an important role in relieving liver disease-relatedsymptoms through anti-inflammatory organ-protective andaggregate removal functions Furthermore the anticancereffects of Radix Bupleuri could be attributed to its autophagyinduction Radix Bupleuri has been found to be an effectivetreatment against depression by regulating metabolite hor-mone and neurotransmitter levels via autophagy-mediatedlipid metabolism [113]

59 Other Pharmacological Effects The effect of the ethanolextract from Radix Bupleuri on cytochrome 450 isoformactivities using a six-drug cocktail approach was evaluatedthe results demonstrated that Radix Bupleuri had stronginduction activity on the CYP2E1 CYP2D6 and CYP3A4which may lead to potential plant drug-drug interactions[114] Radix Bupleuri was shown to be the inhibitor of 120573-glucuronidase The inhibition rate of Radix Bupleuri extractsRB1 (high molecular weight polysaccharides) RB2 (ethanolsolublewater insoluble component) RB3 (extracted by n-butanol soluble in water) and RB4 (low molecular weightwater soluble parts) on the activity of 120573-glucuronidase wasfound to be 4515 3394 2494 and 3454 respectively[115] In pentylenetetrazol (PTZ) induced epilepsy ratsmodelSSa isolated fromRadix Bupleuri significantly reduced seizureseverity and duration while it markedly elevated seizurelatency and downregulated the cytokines expression of p-mTOR p-70S6K L-1120573 and TNF-120572 through inhibitingmTORsignaling pathway [116] He et al demonstrated that SSa obvi-ously reduced lipoprotein uptake to block foamcell formationand the expression of LOX-1 and CD36 boosted cholesterolefflux and the expression of ABCA1 and PPAR120574 throughinhibiting PI3KAktNF-120581BNLRP3 signaling pathway [117]

In another experiment SSc exerted a potent effect on induc-ing human umbilical vein endothelial cells (HUVECs) via-bility and growth Furthermore SSc also induced endothelialcells migration and capillary tube formation The underlyingmechanisms might be related to the gene expression oractivation of matrix metalloproteinase-2 (MMP-2) vascularendothelial growth factor (VEGF) and the p42p44mitogen-activated protein kinase (MAPK ERK) [118] In addition SScwas shown to exhibit inhibitory activities against Alzheimerrsquosdisease (AD) via suppressing the secretion ofA120573 peptides andabnormal tau hyperphosphorylation-mediated microtubuledepolymerization Moreover SSc suppressed A120573 peptide-induced brain endothelial apoptosis indicating that Sscmight be a novel therapeutic tool for treating human AD andother neurodegenerative diseases [119] It was shown by Liuet al for the first time that four polyacetylenes (36ndash39) fromRadix Bupleuri potently exhibited an antidepressant activityby inhibiting the reuptake of serotonin norepinephrine anddopamine The mechanism might be mediated by increasingthe level of monoamines particularly 5-HT andNE [56] Zhuet al suggested that SSa and SSd exhibited the anthelminticactivity against Dactylogyrus spp infecting goldfish Theeffective concentration (EC50) values for SSa and SSd were146 and 074mgminus1 respectively [120]

510 Summary of Pharmacological Effects Radix Bupleuripossesses awide spectrumof pharmacological effects includ-ing anti-inflammatory effect anticancer effect antiviraleffect antipyretic effect antibacterial effect hepatoprotectiveeffect and immunomodulatory effect (Table 3) Based onthese pharmacological effects we can conclude that theextracts and the compounds from this plant can preventor treat certain diseases such as cancer fever malariahepatitis and AD However there is not enough systemicdata of these chemical compounds and their pharmacologicaleffects Thus in the future the pharmacological effects andthe possible molecular mechanisms of the pharmacologicalactivities of Radix Bupleurimust be urgently explored on ourmodern understanding of these diseasesrsquo pathophysiologies

6 Toxicology

Radix Bupleuri has been used for thousands of years asan important traditional herb in China However the toxiceffects of Radix Bupleuri in clinical applications have beengradually reported Several studies have found that the liveris the main organ affected by toxicity particularly in long-term use Major symptoms of liver injury induced by RadixBupleuri included transaminase lifts hepatitis and jaundiceHowever liver functions can return to normal levels aftera specific period [121] Radix Bupleuri has been reportedto exhibit acute hepatitis and acute hepatic necrosis Themean total daily dose was 180 plusmn 335 g which was morethan the Chinese Pharmacopoeia recommended range of 3to 10 g [122] Moreover Radix Bupleuri had been implicatedinmultiple cases of acute hepatitis both as an ingredient aloneand within a particular formulation ldquoXiao-Chai-Hu-Tangrdquo(also known as Syo-Saiko-To in Japanese) [123] Lee et al

demonstrated that two Chinese herbal products containingRadix Bupleuri might increase their risks of liver injuryin HBV-infected patients However further mechanisticresearch on the hepatotoxicity of Radix Bupleuri in thepresence ofHBV infection is warranted [124] In addition theessential oil of Radix Bupleuri induced acute hepatotoxicitywith asynchronous state higher heart rate and fast breathing[125] The total saponins isolated from Radix Bupleuri couldalso cause evidently liver damage in dose-dependent mannermanifested as hepatocyte organic lesion and liver functionchanges as well as hepatocyte death [126]

7 Pharmacokinetics

A selective and sensitive LC-MSMS method was developedand validated for simultaneous determination of SSa b2 cand d in rat plasma afteroral administration of the ethanol-water (50 50 vv) extract of Radix Bupleuri for the firsttime The results demonstrated that SSa c and d wereabsorbed rapidly with 119879max less than 30min [127] In anotherpharmacokinetics experiment of rats Liu et al was the first todevelop an UPLC-PDA-MS method to determine the phar-macokinetics of four polyacetylenes after ig administrationof 95 ethanol extract of Radix Bupleuri The results showedthat compounds 36 and 38 were not detected in rat serumwhereas compounds 37 and 39 exerted a fast distributionphase followed by a relatively slow elimination phase (119905121199114ndash7 h) [56]

8 Future Perspectives and Conclusions

In traditional Chinese medicine Radix Bupleuri has longbeen used regulate the exterior and interiormetabolisms dis-perse evil heat from superficies sooth the liver and promoteyang and qi It has been widely used to treat various diseasesin China Japan Korea and other Asian countries for manycenturies A total of 74 compounds including essential oilstriterpenoid saponins polyacetylenes flavonoids lignansfatty acids and sterols have been isolated and identifiedfrom Radix Bupleuri [39ndash65] Pharmacological studies haverevealed that Radix Bupleuri possesses a variety of biologicaleffects including anti-inflammatory anticancer antiviralantipyretic antibacterial antiobesity immunomodulatoryhepatoprotective neuroprotective and autophagic effects[66ndash120] However there are some aspects that need to befurther investigated

Radix Bupleuri is an ingredient of many patent medicinesor prescriptions Although modern experiments have con-firmed that this drug alone exhibits multiple pharmacolog-ical activities it is important to investigate the molecularmechanisms of Radix Bupleuri combined with other herbsbased on traditional uses Furthermore the pharmacologicaleffects of only a few of the ingredients such as saikosaponinsflavonoids and the essential oils have been investigatedSome polyacetylenes lignans and sterols have not beensufficiently researched in terms of their pharmacologicaleffects Radix Bupleuri shows both hepatoprotection and

hepatotoxicity which appears to be contradictory This phe-nomenon is similar to that of PolygonummultiflorumThunb[128] Based on the literature the main reasons are likelythe administration dosage and delivery time High doses andlong-term drug delivery are more likely to result in livertoxicity whereas low doses and short-term drug deliverymight result in liver protection Therefore this issue needsfurther study

In conclusion this review summarized the traditionaluses botany phytochemistry pharmacology and toxicologyof Radix Bupleuri Moreover it has provided a new founda-tion for further research on its mechanism of action and thedevelopment of better therapeutic agents employing RadixBupleuri in the future It is anticipated that the comprehen-sive and detailed research on toxicity pharmacodynamicspharmacokinetics and molecular mechanism are necessaryto be explored to develop its bioactive compounds as effectivedrugs

metabolisms disperse evil heat from superficies sooth theliver and promote yang and qi [1]Radix Bupleuriwas initiallyrecorded in Shennong Bencao Jing a famous monograph oftraditional Chinese medicine written in China in 200 AD[17] According to a record of traditional Chinese medicinedated 2000 years ago Radix Bupleuri had mainly been usedfor the treatment of mouth-bitterness throat-drying andeyes-dazzling In other monographs of Materia Medica suchas Jin Kui Yao Lue Kaibao Bencao Bencao Gangmu andXinbian Bencao this plant was described to be used for thetreatment of common cold with fever influenza hepatitismalaria menoxenia and hyperlipidemia [18] CurrentlyRadix Bupleuri exerts other pharmacological effects suchas balancing different organs and energies within the bodystrengthening the action of the digestive tract improving liverand circulatory system function and relieving liver tension[19] Therefore it is also used as a popular tonic herb inChina In Korea and Japan this plant is commonly used forthe treatment of fever pain and inflammation associatedwith influenza and the common cold [20] In addition thisplant is also used as analgesics in the treatment of distendingpain in the hypochondriac region of the chest and againstamenorrhoea

Radix Bupleuri is combined with other herbs in manyclassical formulas to improve clinical effect Xiaoyaosan(XYS) a well-known formula for relieving depression isoriginated from the book of ldquoTaiping Huimin Heji Jufangrdquo inSong Dynasty (960ndash1279 AD) consisting of Radix BupleuriRadix Angelicae Sinensis Radix Paeoniae Alba RhizomaAtractylodis Macrocephalae Poria Radix GlycyrrhizaeHerbaMenthae and Rhizoma Zingiberis Recens XYS exerts var-ious pharmacological effects including soothing the liverand improving the circulation of qi to relieve depressionFurthermore it has been commonly recognized as a safe andeffective prescription in the treatment of depressive disorder[21ndash23] The 2015 edition of the Chinese Pharmacopoeialists 97 Chinese patent medicines containing Radix Bupleuriand the compatible herbs that are more frequently describedincludeRadixGlycyrrhizaeRhizomaZingiberis RecensRadixScutellariae and Panax ginseng Table 1 lists subsets of theChinese patent drugs containing Radix Bupleuri in differentformulations Although Radix Bupleuri has been used to treatcertain diseases in ethnomedicines for thousands of yearsthis herbal medicine should be comprehensively understoodand recent information should be obtained for its clinical use

3 Botanical Characterization and Distribution

According to the Chinese pharmacopoeia Radix Bupleuri isderived from the dried roots of Bupleurum chinense DC andBupleurum scorzonerifolium Willd (Figure 1) The former isknown as ldquoBeichaihurdquo (Northern Chinese Thorowax Root)and the latter is known as ldquoNanchaihurdquo (Southern ChineseThorowax Root) due to the difference of the origin anddescription The drug is collected in spring or autumnremoved from the aerial part and soil and dried

Beichaihu As a herbaceous perennial plant Bupleurum chi-nenseDC grows to the height of 50ndash85 cm Its root is conical

taupe and approximately 6ndash20 cm in length Its stems areerect tufted and apex branched The leaves are alternate theleaf blades are broadly linear-lanceolate 4ndash7 times 06ndash08 cm insize the apex is acuminate Compound umbels are axillaryand terminal approximately 1ndash4 cm in length the bracts are0 or 2-3 linear the petals are 5 and bright yellow The fruitsare oblong brown and approximately 3mm in length Theyblossom from July to September and fruit from August toOctober This plant is widely cultivated in China Japan andKorea Moreover it grows in grasslands stream banks sunnyslopes and roadsides and other locations with altitudes of100ndash2700m [24]

Nanchaihu Bupleurum scorzonerifolium Willd is a herba-ceous perennial plant and approximately 30ndash60 cm high Itsroot is flexuose reddish brown and approximately 4ndash10 cmin length Its stems are 1ndash3 usually glabrous and apexbranchedThe leaf blades are linear or linear-lanceolate 6ndash16times 02ndash07 cm in size the apex is acuminate Compoundumbels are axillary and terminal the bracts are 1ndash3 thepetals are 5 and yellow The fruits are ellipsoid dark brownapproximately 2-3mm in length They blossom from Julyto August and fruit from August to October This plant isalso widely cultivated in East Asian countries such as ChinaJapan and Korea It grows in shrub forest margins sunnymountain slopes dry grasslands and other locations withaltitudes of 200ndash3000m [24]

There were approximately 36 Bupleurum species andvarieties in different districts and markets due to the slightlydifferent morphologic appearance of Bupleurum plantsincluding B longiradiatum Turcz with toxic ingredients andB hamiltonii Balak with very little active constituents [2526] Inevitably this situation will compromise the values ofRadix Bupleuri and even imperil the safety of the consumersUntil now several techniques have been developed to identifyand distinguish them including TLC [27] HPLC [28ndash30]HPLC-ELSD [31 32] HPLC-MS [33 34] UPLC-MS [35] andcapillary electrochromatography [36] Among thesemethodsmentioned above HPLC-ELSD is the most commonly usedanalytical method for evaluating the quality and authenticityof Radix Bupleuri The total amounts of saikosaponins a andd are used as the indicator compounds to characterize thequality of this plant with minimum contents of 03 in thePharmacopoeia of Peoplersquos Republic of China

4 Chemical Constituents

In the past few decades approximately 74 compounds havebeen isolated from Radix Bupleuri including essential oilstriterpenoid saponins polyacetylenes flavonoids lignansfatty acids and sterols Triterpenoid saponins flavonoidsand essential oil which possess multiple pharmacologicalactivities are considered as the main active ingredients ofRadix Bupleuri Their structures are shown in (Table 2)(Figures 2ndash6)

41 Volatile Compounds (Essential Oils) The essential oils ofRadix Bupleuri are regarded as one of the most important

56 Hepatoprotective Effects The liver protective effectsagainst CCl4 induced liver injury were investigated aftertreatment ofmicewith raw and vinegar-bakedRadix Bupleuri(5 gkgday) for 14 days The results showed that both rawand processed Radix Bupleuri showed liver protective effectsagainst CCl4 induced liver injury and the vinegar-bakedRadix Bupleuri exerted better effects than that of raw RadixBupleuri [96] Pretreated with saikosaponins especially SSaor SSd showed remarkable inhibition of D-galactosamine-induced hepatic injury through decreasing the activity ofglucose-6-phosphatase and NADPH-cytochrome C reduc-tase and increasing 51015840-nucleotidase activity [97] Similarlybupleurosides III VI IX and XIII and saikosaponin b3isolated from Bupleurum scorzonerifolium Willd were alsofound to exhibit protective effect on the D-galactosamine-induced cytotoxicity in primary cultured rat hepatocytes[98] Further studies also demonstrated that the protectiveeffects of saikosaponins isolated from Bupleurum chinenseDC could prevent hepatocyte injury through regulatingintracellular calcium levels [99] In a rat model with CCl4induced acute hepatic injury the hepatic enzyme levels (GOTGPT and ALP) and the lipid peroxidation in the liver weresignificantly reduced by the administration of SSd [100]Additionally SSd significantly reduced collagen I depositionand alanine aminotransferase level on liver fibrosis rats anddecreased the concentration of transforming growth factor1205731 (TGF-1205731) Moreover SSd was able to alleviate hepatocyteinjury from oxidative stressThe effect of SSd on liver fibrosismay be related to its ability to reduce lipid peroxidation [101]

57 Immunomodulatory Effects Yamakage et al determinedthe effects of Radix Bupleuri on spontaneous lymphaticvessel activity The results indicated that Radix Bupleurisignificantly increased the amplitude of spontaneous activityof lymphatic vessels in a concentration-dependent mannerand the mechanisms of this effect seem to be independent ofendothelial function [102] Eugenin (46) and saikochrome A(47) isolated from the MeOH extracts from Bupleurum scor-zonerifolium possessed immunosuppressive effect on humanperipheral blood T cells via inhibiting CD28-costimulatedactivation [62] SSd (10mg intraperitoneally) significantlyactivated peritoneal macrophages in terms of enhancementof phagocytic activity increased level of cellular lysosomalenzyme and suppressed the response of plaque-forming cellsto heterologous erythrocytes by stimulating T and B cells ina dose-dependent manner [103] Moreover SSd modulated

lymphocyte activity through suppressing the T cell responseand increasing the B cell response to different mitogensand the interleukin- (IL-) 2IL-4 production through areceptor-bypassed pathway [41 104 105] In another exper-iment Wong et al found that SSd was shown to inhibitOKT3CD28-costimulated human T cell proliferation andPMA PMAionomycin and Con A-induced mouse T cellactivation in vitro The underlying mechanisms involveddownregulation of NF-kB signaling by suppression of IKKand Akt activities [106]

58 Autophagic Effect Autophagy is a complex processin cells which occurs through the formation of double-membrane vesicles (autophagosomes) which are engulfedby cytoplasmic molecules Then the autophagosome fuseswith the lysosomes leading to degradation of long-livedproteins aggregated proteins and damaged organelles [107ndash109] Moreover autophagy might be triggered by hypoxianutritional deprivation radiation chemical drugs and otherstimulants [110] Autophagy contributes to the pathogenesisof diverse diseases such as neuronal degeneration inflamma-tory bowel disease aging and cancer [111 112] In the previousstudy Law et al demonstrated that the protective pharma-cological effects of Radix Bupleuri might be attributed to itsautophagy inductionThe autophagic effect of Radix Bupleuriplayed an important role in relieving liver disease-relatedsymptoms through anti-inflammatory organ-protective andaggregate removal functions Furthermore the anticancereffects of Radix Bupleuri could be attributed to its autophagyinduction Radix Bupleuri has been found to be an effectivetreatment against depression by regulating metabolite hor-mone and neurotransmitter levels via autophagy-mediatedlipid metabolism [113]

59 Other Pharmacological Effects The effect of the ethanolextract from Radix Bupleuri on cytochrome 450 isoformactivities using a six-drug cocktail approach was evaluatedthe results demonstrated that Radix Bupleuri had stronginduction activity on the CYP2E1 CYP2D6 and CYP3A4which may lead to potential plant drug-drug interactions[114] Radix Bupleuri was shown to be the inhibitor of 120573-glucuronidase The inhibition rate of Radix Bupleuri extractsRB1 (high molecular weight polysaccharides) RB2 (ethanolsolublewater insoluble component) RB3 (extracted by n-butanol soluble in water) and RB4 (low molecular weightwater soluble parts) on the activity of 120573-glucuronidase wasfound to be 4515 3394 2494 and 3454 respectively[115] In pentylenetetrazol (PTZ) induced epilepsy ratsmodelSSa isolated fromRadix Bupleuri significantly reduced seizureseverity and duration while it markedly elevated seizurelatency and downregulated the cytokines expression of p-mTOR p-70S6K L-1120573 and TNF-120572 through inhibitingmTORsignaling pathway [116] He et al demonstrated that SSa obvi-ously reduced lipoprotein uptake to block foamcell formationand the expression of LOX-1 and CD36 boosted cholesterolefflux and the expression of ABCA1 and PPAR120574 throughinhibiting PI3KAktNF-120581BNLRP3 signaling pathway [117]

In another experiment SSc exerted a potent effect on induc-ing human umbilical vein endothelial cells (HUVECs) via-bility and growth Furthermore SSc also induced endothelialcells migration and capillary tube formation The underlyingmechanisms might be related to the gene expression oractivation of matrix metalloproteinase-2 (MMP-2) vascularendothelial growth factor (VEGF) and the p42p44mitogen-activated protein kinase (MAPK ERK) [118] In addition SScwas shown to exhibit inhibitory activities against Alzheimerrsquosdisease (AD) via suppressing the secretion ofA120573 peptides andabnormal tau hyperphosphorylation-mediated microtubuledepolymerization Moreover SSc suppressed A120573 peptide-induced brain endothelial apoptosis indicating that Sscmight be a novel therapeutic tool for treating human AD andother neurodegenerative diseases [119] It was shown by Liuet al for the first time that four polyacetylenes (36ndash39) fromRadix Bupleuri potently exhibited an antidepressant activityby inhibiting the reuptake of serotonin norepinephrine anddopamine The mechanism might be mediated by increasingthe level of monoamines particularly 5-HT andNE [56] Zhuet al suggested that SSa and SSd exhibited the anthelminticactivity against Dactylogyrus spp infecting goldfish Theeffective concentration (EC50) values for SSa and SSd were146 and 074mgminus1 respectively [120]

510 Summary of Pharmacological Effects Radix Bupleuripossesses awide spectrumof pharmacological effects includ-ing anti-inflammatory effect anticancer effect antiviraleffect antipyretic effect antibacterial effect hepatoprotectiveeffect and immunomodulatory effect (Table 3) Based onthese pharmacological effects we can conclude that theextracts and the compounds from this plant can preventor treat certain diseases such as cancer fever malariahepatitis and AD However there is not enough systemicdata of these chemical compounds and their pharmacologicaleffects Thus in the future the pharmacological effects andthe possible molecular mechanisms of the pharmacologicalactivities of Radix Bupleurimust be urgently explored on ourmodern understanding of these diseasesrsquo pathophysiologies

6 Toxicology

Radix Bupleuri has been used for thousands of years asan important traditional herb in China However the toxiceffects of Radix Bupleuri in clinical applications have beengradually reported Several studies have found that the liveris the main organ affected by toxicity particularly in long-term use Major symptoms of liver injury induced by RadixBupleuri included transaminase lifts hepatitis and jaundiceHowever liver functions can return to normal levels aftera specific period [121] Radix Bupleuri has been reportedto exhibit acute hepatitis and acute hepatic necrosis Themean total daily dose was 180 plusmn 335 g which was morethan the Chinese Pharmacopoeia recommended range of 3to 10 g [122] Moreover Radix Bupleuri had been implicatedinmultiple cases of acute hepatitis both as an ingredient aloneand within a particular formulation ldquoXiao-Chai-Hu-Tangrdquo(also known as Syo-Saiko-To in Japanese) [123] Lee et al

demonstrated that two Chinese herbal products containingRadix Bupleuri might increase their risks of liver injuryin HBV-infected patients However further mechanisticresearch on the hepatotoxicity of Radix Bupleuri in thepresence ofHBV infection is warranted [124] In addition theessential oil of Radix Bupleuri induced acute hepatotoxicitywith asynchronous state higher heart rate and fast breathing[125] The total saponins isolated from Radix Bupleuri couldalso cause evidently liver damage in dose-dependent mannermanifested as hepatocyte organic lesion and liver functionchanges as well as hepatocyte death [126]

7 Pharmacokinetics

A selective and sensitive LC-MSMS method was developedand validated for simultaneous determination of SSa b2 cand d in rat plasma afteroral administration of the ethanol-water (50 50 vv) extract of Radix Bupleuri for the firsttime The results demonstrated that SSa c and d wereabsorbed rapidly with 119879max less than 30min [127] In anotherpharmacokinetics experiment of rats Liu et al was the first todevelop an UPLC-PDA-MS method to determine the phar-macokinetics of four polyacetylenes after ig administrationof 95 ethanol extract of Radix Bupleuri The results showedthat compounds 36 and 38 were not detected in rat serumwhereas compounds 37 and 39 exerted a fast distributionphase followed by a relatively slow elimination phase (119905121199114ndash7 h) [56]

8 Future Perspectives and Conclusions

In traditional Chinese medicine Radix Bupleuri has longbeen used regulate the exterior and interiormetabolisms dis-perse evil heat from superficies sooth the liver and promoteyang and qi It has been widely used to treat various diseasesin China Japan Korea and other Asian countries for manycenturies A total of 74 compounds including essential oilstriterpenoid saponins polyacetylenes flavonoids lignansfatty acids and sterols have been isolated and identifiedfrom Radix Bupleuri [39ndash65] Pharmacological studies haverevealed that Radix Bupleuri possesses a variety of biologicaleffects including anti-inflammatory anticancer antiviralantipyretic antibacterial antiobesity immunomodulatoryhepatoprotective neuroprotective and autophagic effects[66ndash120] However there are some aspects that need to befurther investigated

Radix Bupleuri is an ingredient of many patent medicinesor prescriptions Although modern experiments have con-firmed that this drug alone exhibits multiple pharmacolog-ical activities it is important to investigate the molecularmechanisms of Radix Bupleuri combined with other herbsbased on traditional uses Furthermore the pharmacologicaleffects of only a few of the ingredients such as saikosaponinsflavonoids and the essential oils have been investigatedSome polyacetylenes lignans and sterols have not beensufficiently researched in terms of their pharmacologicaleffects Radix Bupleuri shows both hepatoprotection and

hepatotoxicity which appears to be contradictory This phe-nomenon is similar to that of PolygonummultiflorumThunb[128] Based on the literature the main reasons are likelythe administration dosage and delivery time High doses andlong-term drug delivery are more likely to result in livertoxicity whereas low doses and short-term drug deliverymight result in liver protection Therefore this issue needsfurther study

In conclusion this review summarized the traditionaluses botany phytochemistry pharmacology and toxicologyof Radix Bupleuri Moreover it has provided a new founda-tion for further research on its mechanism of action and thedevelopment of better therapeutic agents employing RadixBupleuri in the future It is anticipated that the comprehen-sive and detailed research on toxicity pharmacodynamicspharmacokinetics and molecular mechanism are necessaryto be explored to develop its bioactive compounds as effectivedrugs

51 Anti-inflammatory Effects Radix Bupleuri has beenwidely used for the treatment of several types of chronicinflammatory diseases The crude polysaccharides(80mgkg) isolated from the roots of Bupleurum chinenseDC significantly attenuated lung injury by inhibiting thelevel of myeloperoxidase (MPO) tumor necrosis factor-120572(TNF-120572) and serum nitric oxide (NO) [66] Chun et alreported that saikosaponins from Radix Bupleuri exhibitedanti-inflammatory activity on inflammatory processesincluding inhibition of inflammatory exudation capillarypermeability inflammatory mediators release migrationof white cells connective tissue hyperplasia and a varietyof allergic inflammation [67] Ma et al was the first toshow that saikosaponins exerted anti-inflammatory activityon paw edema mainly via regulating the nicotinate andnicotinamide metabolism and arachidonic acid metabolism[5] Zhu et al found that saikosaponin a (SSa) exhibitedan inhibitory effect on proinflammatory cytokines inLPS-stimulated macrophages The mechanism of theseactions involved the regulation of MAPK and NF-120581B signalspathways [68] In another study SSa dose-dependentlyinhibited the production of ROS TNF-120572 IL-8 COX-2 andiNOS in LPS-stimulated human umbilical endothelial cells(HUVECs) by upregulating of the LXR120572-ABCA1 signalingpathway [69] Moreover Lee et al showed that saikosaponinc (SSc) was also shown to inhibited LPS-induced apoptosis inHUVECs via inhibition of caspase-3 activation and caspase-3-mediated-FAK degradation [70] Zhao et al showed thatSSa also suppressed TNF-120572 and IL-6 concentrations inthe intestines of septic rats through the inhibition of thenucleotide-binding oligomerization domain 2 (NOD2)NF-120581B signaling pathway [71] Saikosaponin d (SSd) has beenreported to inhibit PGE2 production and intracellular freeCa2+ concentration ([Ca2+]i) in a concentration-dependentmanner with an IC50 value of 3 120583m in C6 rat glioma cells[72]

In addition several studies showed that a widerange of Radix Bupleuri preparations also exhibited anti-inflammatory effects in in vitro and in vivo model Li et alshowed that Saireito and its active components (SSd) couldsuppress the proliferation of mesangial cells and expansionof the mesangial matrix in the rat glomerulonephritismodel [73] In experimental chronic pancreatitis rats modelldquoChai-hu-shu-gan powderrdquo exerted anti-inflammatory andantifibrotic effects by inhibiting the expression of nuclearfactor-120581B (NF-120581B) and TNF-120572 mRNA in the pancreas [74]Furthermore it also reduced the abnormally high plasmalevel of cholecystokinin improved the gastricmovement andavoided nausea and flatulence [75] In another experimenta Chinese herbal formula called ldquoRCM-101rdquo (containingFlos magnoliae Radix Bupleuri Radix Glycyrrhizae RadixAngelicae Sinensis etc) inhibited the NO production andiNOS protein expression in LPS-stimulated rat aorta andRaw 2647 macrophages [76]

52 Anticancer Effects The extracts and compounds ofRadix Bupleuri also possessed anticancerantitumor effectThe acetone extract of Bupleurum scorzonerifolium couldinhibit the proliferation of A549 human lung cancer cellsin a dose-dependent manner via causing cell cycle arrestin the G2M phase increasing microtubule stabilizationsuppressing telomerase activity activating ERK 12 andcaspase-39 in A549 cells [77ndash79] Saponins isolated fromRadix Bupleuri also exhibited significantly anti-proliferativeactivity in human non-small cell lung cancer A549 cellsthrough Fas-dependent apoptotic pathway [80] Su et alfound that thewater extracts ofRadix Bupleuri could enhance5-fluorouracil-induced cytotoxicity in HepG2 hepatoma cellsthrough cell arrest at the late G1early S phase while pro-tecting normal blood lymphocytes [6] SSd showed verypotent activity against the HepG2 cell line with an IC50value of 125mgml The mechanism of cytotoxicity was

Several Chinese medicine preparations containing RadixBupleuri also have been traditionally used in the treatmentof tumors and cancer The water extracts of ldquoLong DanXie Gan Wanrdquo exerted a significant growth inhibitory effectin HL60 and HT29 cancer cell lines indicating that thisformulation may possess some chemotherapeutic potential[83] Treatment with ldquoxiao-chai-hu decoctionrdquo exhibited asignificantly lower incidence of hepatocellular carcinoma andreductions in cancer pain and tumor size The underlyingmechanismof the antitumor activities is based on stimulationof the reticuloendothelial system (RES) and is closely relatedof TNF production [84ndash86]

53 Antiviral Effects Wen et al reported that the acetoneextract of Radix Bupleuri possessed a significant antiviruseffect on acute respiratory tract infections with H1N1 virusinfection and suppressed influenzaAvirus-inducedRANTESsecretion in H1N1-infected A549 cells at a concentration of

100 and 200120583gml suggesting that Radix Bupleuri might bebeneficial for the treatment of chronic inflammatory condi-tions followed by viral infection [10] SSc has been reportedto show effective anti-HBV activity through inhibiting DNAexpression of HBsAg HBeAg and HBV [81] Treatmentwith ldquoxiao-chai-hu decoctionrdquo (20120583gml 3 days 20120583gml6 days) could inhibit the production of HBV (119875 lt 00001)and the expression of HBeAg Moreover crude saponinsof Bupleurum chinense DC could inhibit the replication ofHBV (119875 lt 00001) [87] Similarly in another study Yinet al showed that SSd isolated from the MeOH extract ofBupleurum chinense DC exhibited significant bioactivity ininhibitingDNA replication ofHBV [88]The antiviral activityof saikosaponins (a b2 c and d) and their mode of actinwere examined The results showed that all saikosaponinsexerted antiviral activity on human coronavirus-229E atconcentrations of 025ndash25120583m and the strongest activity wasobserved for saikosaponin b2 with an IC50 of 17 120583m Thismechanism might involve interference in the early stage ofviral replication such as absorption and penetration of thevirus [89]

adjustment of synthesis and exudation of cyclic adenosinemonophosphate (cAMP) and arginine vasopressin (AVP)[90] A novel in situ gel system for nasal delivery of theessential oil from Radix Bupleuri was prepared The resultssuggested that Radix Bupleuri in situ gel can be moreeffective than the solution in the treatment of fever [91] Asimilar study showed that the essential oil extracted from the

herb exhibited dose-dependent antipyretic capacity on bothfevered rabbits and rats [92]

55 Antibacterial Effects The ethanol extract of Bupleu-rum chinense DC exerted a remarkable bacteriostaticeffect on Gram-negative microorganism Helicobacter pyloriThe bioactive minimum inhibitory concentration (MIC)

value was 60Mm [93] Saikosaponins isolated from RadixBupleuri have been reported to exhibit antibacterial activityparticularly against Pseudomonas aeruginosa and Listeriamonocytogenes The protective effect was attributed to theimmunomodulatory action on macrophages [94] ldquoChaihuinjectionrdquo has also been tested for possible antimicrobialactivity in vitroThe results demonstrated thatmild inhibitionof Staphylococcus aureus was observed but no effects wereobserved against Staphylococcus albusNeisseria gonorrhoeaeDiplococcus pneumoniae haemolytic Streptococcus or Pseu-domonas aeruginosa [95]

56 Hepatoprotective Effects The liver protective effectsagainst CCl4 induced liver injury were investigated aftertreatment ofmicewith raw and vinegar-bakedRadix Bupleuri(5 gkgday) for 14 days The results showed that both rawand processed Radix Bupleuri showed liver protective effectsagainst CCl4 induced liver injury and the vinegar-bakedRadix Bupleuri exerted better effects than that of raw RadixBupleuri [96] Pretreated with saikosaponins especially SSaor SSd showed remarkable inhibition of D-galactosamine-induced hepatic injury through decreasing the activity ofglucose-6-phosphatase and NADPH-cytochrome C reduc-tase and increasing 51015840-nucleotidase activity [97] Similarlybupleurosides III VI IX and XIII and saikosaponin b3isolated from Bupleurum scorzonerifolium Willd were alsofound to exhibit protective effect on the D-galactosamine-induced cytotoxicity in primary cultured rat hepatocytes[98] Further studies also demonstrated that the protectiveeffects of saikosaponins isolated from Bupleurum chinenseDC could prevent hepatocyte injury through regulatingintracellular calcium levels [99] In a rat model with CCl4induced acute hepatic injury the hepatic enzyme levels (GOTGPT and ALP) and the lipid peroxidation in the liver weresignificantly reduced by the administration of SSd [100]Additionally SSd significantly reduced collagen I depositionand alanine aminotransferase level on liver fibrosis rats anddecreased the concentration of transforming growth factor1205731 (TGF-1205731) Moreover SSd was able to alleviate hepatocyteinjury from oxidative stressThe effect of SSd on liver fibrosismay be related to its ability to reduce lipid peroxidation [101]

57 Immunomodulatory Effects Yamakage et al determinedthe effects of Radix Bupleuri on spontaneous lymphaticvessel activity The results indicated that Radix Bupleurisignificantly increased the amplitude of spontaneous activityof lymphatic vessels in a concentration-dependent mannerand the mechanisms of this effect seem to be independent ofendothelial function [102] Eugenin (46) and saikochrome A(47) isolated from the MeOH extracts from Bupleurum scor-zonerifolium possessed immunosuppressive effect on humanperipheral blood T cells via inhibiting CD28-costimulatedactivation [62] SSd (10mg intraperitoneally) significantlyactivated peritoneal macrophages in terms of enhancementof phagocytic activity increased level of cellular lysosomalenzyme and suppressed the response of plaque-forming cellsto heterologous erythrocytes by stimulating T and B cells ina dose-dependent manner [103] Moreover SSd modulated

lymphocyte activity through suppressing the T cell responseand increasing the B cell response to different mitogensand the interleukin- (IL-) 2IL-4 production through areceptor-bypassed pathway [41 104 105] In another exper-iment Wong et al found that SSd was shown to inhibitOKT3CD28-costimulated human T cell proliferation andPMA PMAionomycin and Con A-induced mouse T cellactivation in vitro The underlying mechanisms involveddownregulation of NF-kB signaling by suppression of IKKand Akt activities [106]

58 Autophagic Effect Autophagy is a complex processin cells which occurs through the formation of double-membrane vesicles (autophagosomes) which are engulfedby cytoplasmic molecules Then the autophagosome fuseswith the lysosomes leading to degradation of long-livedproteins aggregated proteins and damaged organelles [107ndash109] Moreover autophagy might be triggered by hypoxianutritional deprivation radiation chemical drugs and otherstimulants [110] Autophagy contributes to the pathogenesisof diverse diseases such as neuronal degeneration inflamma-tory bowel disease aging and cancer [111 112] In the previousstudy Law et al demonstrated that the protective pharma-cological effects of Radix Bupleuri might be attributed to itsautophagy inductionThe autophagic effect of Radix Bupleuriplayed an important role in relieving liver disease-relatedsymptoms through anti-inflammatory organ-protective andaggregate removal functions Furthermore the anticancereffects of Radix Bupleuri could be attributed to its autophagyinduction Radix Bupleuri has been found to be an effectivetreatment against depression by regulating metabolite hor-mone and neurotransmitter levels via autophagy-mediatedlipid metabolism [113]

59 Other Pharmacological Effects The effect of the ethanolextract from Radix Bupleuri on cytochrome 450 isoformactivities using a six-drug cocktail approach was evaluatedthe results demonstrated that Radix Bupleuri had stronginduction activity on the CYP2E1 CYP2D6 and CYP3A4which may lead to potential plant drug-drug interactions[114] Radix Bupleuri was shown to be the inhibitor of 120573-glucuronidase The inhibition rate of Radix Bupleuri extractsRB1 (high molecular weight polysaccharides) RB2 (ethanolsolublewater insoluble component) RB3 (extracted by n-butanol soluble in water) and RB4 (low molecular weightwater soluble parts) on the activity of 120573-glucuronidase wasfound to be 4515 3394 2494 and 3454 respectively[115] In pentylenetetrazol (PTZ) induced epilepsy ratsmodelSSa isolated fromRadix Bupleuri significantly reduced seizureseverity and duration while it markedly elevated seizurelatency and downregulated the cytokines expression of p-mTOR p-70S6K L-1120573 and TNF-120572 through inhibitingmTORsignaling pathway [116] He et al demonstrated that SSa obvi-ously reduced lipoprotein uptake to block foamcell formationand the expression of LOX-1 and CD36 boosted cholesterolefflux and the expression of ABCA1 and PPAR120574 throughinhibiting PI3KAktNF-120581BNLRP3 signaling pathway [117]

In another experiment SSc exerted a potent effect on induc-ing human umbilical vein endothelial cells (HUVECs) via-bility and growth Furthermore SSc also induced endothelialcells migration and capillary tube formation The underlyingmechanisms might be related to the gene expression oractivation of matrix metalloproteinase-2 (MMP-2) vascularendothelial growth factor (VEGF) and the p42p44mitogen-activated protein kinase (MAPK ERK) [118] In addition SScwas shown to exhibit inhibitory activities against Alzheimerrsquosdisease (AD) via suppressing the secretion ofA120573 peptides andabnormal tau hyperphosphorylation-mediated microtubuledepolymerization Moreover SSc suppressed A120573 peptide-induced brain endothelial apoptosis indicating that Sscmight be a novel therapeutic tool for treating human AD andother neurodegenerative diseases [119] It was shown by Liuet al for the first time that four polyacetylenes (36ndash39) fromRadix Bupleuri potently exhibited an antidepressant activityby inhibiting the reuptake of serotonin norepinephrine anddopamine The mechanism might be mediated by increasingthe level of monoamines particularly 5-HT andNE [56] Zhuet al suggested that SSa and SSd exhibited the anthelminticactivity against Dactylogyrus spp infecting goldfish Theeffective concentration (EC50) values for SSa and SSd were146 and 074mgminus1 respectively [120]

510 Summary of Pharmacological Effects Radix Bupleuripossesses awide spectrumof pharmacological effects includ-ing anti-inflammatory effect anticancer effect antiviraleffect antipyretic effect antibacterial effect hepatoprotectiveeffect and immunomodulatory effect (Table 3) Based onthese pharmacological effects we can conclude that theextracts and the compounds from this plant can preventor treat certain diseases such as cancer fever malariahepatitis and AD However there is not enough systemicdata of these chemical compounds and their pharmacologicaleffects Thus in the future the pharmacological effects andthe possible molecular mechanisms of the pharmacologicalactivities of Radix Bupleurimust be urgently explored on ourmodern understanding of these diseasesrsquo pathophysiologies

6 Toxicology

Radix Bupleuri has been used for thousands of years asan important traditional herb in China However the toxiceffects of Radix Bupleuri in clinical applications have beengradually reported Several studies have found that the liveris the main organ affected by toxicity particularly in long-term use Major symptoms of liver injury induced by RadixBupleuri included transaminase lifts hepatitis and jaundiceHowever liver functions can return to normal levels aftera specific period [121] Radix Bupleuri has been reportedto exhibit acute hepatitis and acute hepatic necrosis Themean total daily dose was 180 plusmn 335 g which was morethan the Chinese Pharmacopoeia recommended range of 3to 10 g [122] Moreover Radix Bupleuri had been implicatedinmultiple cases of acute hepatitis both as an ingredient aloneand within a particular formulation ldquoXiao-Chai-Hu-Tangrdquo(also known as Syo-Saiko-To in Japanese) [123] Lee et al

demonstrated that two Chinese herbal products containingRadix Bupleuri might increase their risks of liver injuryin HBV-infected patients However further mechanisticresearch on the hepatotoxicity of Radix Bupleuri in thepresence ofHBV infection is warranted [124] In addition theessential oil of Radix Bupleuri induced acute hepatotoxicitywith asynchronous state higher heart rate and fast breathing[125] The total saponins isolated from Radix Bupleuri couldalso cause evidently liver damage in dose-dependent mannermanifested as hepatocyte organic lesion and liver functionchanges as well as hepatocyte death [126]

7 Pharmacokinetics

A selective and sensitive LC-MSMS method was developedand validated for simultaneous determination of SSa b2 cand d in rat plasma afteroral administration of the ethanol-water (50 50 vv) extract of Radix Bupleuri for the firsttime The results demonstrated that SSa c and d wereabsorbed rapidly with 119879max less than 30min [127] In anotherpharmacokinetics experiment of rats Liu et al was the first todevelop an UPLC-PDA-MS method to determine the phar-macokinetics of four polyacetylenes after ig administrationof 95 ethanol extract of Radix Bupleuri The results showedthat compounds 36 and 38 were not detected in rat serumwhereas compounds 37 and 39 exerted a fast distributionphase followed by a relatively slow elimination phase (119905121199114ndash7 h) [56]

8 Future Perspectives and Conclusions

In traditional Chinese medicine Radix Bupleuri has longbeen used regulate the exterior and interiormetabolisms dis-perse evil heat from superficies sooth the liver and promoteyang and qi It has been widely used to treat various diseasesin China Japan Korea and other Asian countries for manycenturies A total of 74 compounds including essential oilstriterpenoid saponins polyacetylenes flavonoids lignansfatty acids and sterols have been isolated and identifiedfrom Radix Bupleuri [39ndash65] Pharmacological studies haverevealed that Radix Bupleuri possesses a variety of biologicaleffects including anti-inflammatory anticancer antiviralantipyretic antibacterial antiobesity immunomodulatoryhepatoprotective neuroprotective and autophagic effects[66ndash120] However there are some aspects that need to befurther investigated

Radix Bupleuri is an ingredient of many patent medicinesor prescriptions Although modern experiments have con-firmed that this drug alone exhibits multiple pharmacolog-ical activities it is important to investigate the molecularmechanisms of Radix Bupleuri combined with other herbsbased on traditional uses Furthermore the pharmacologicaleffects of only a few of the ingredients such as saikosaponinsflavonoids and the essential oils have been investigatedSome polyacetylenes lignans and sterols have not beensufficiently researched in terms of their pharmacologicaleffects Radix Bupleuri shows both hepatoprotection and

hepatotoxicity which appears to be contradictory This phe-nomenon is similar to that of PolygonummultiflorumThunb[128] Based on the literature the main reasons are likelythe administration dosage and delivery time High doses andlong-term drug delivery are more likely to result in livertoxicity whereas low doses and short-term drug deliverymight result in liver protection Therefore this issue needsfurther study

In conclusion this review summarized the traditionaluses botany phytochemistry pharmacology and toxicologyof Radix Bupleuri Moreover it has provided a new founda-tion for further research on its mechanism of action and thedevelopment of better therapeutic agents employing RadixBupleuri in the future It is anticipated that the comprehen-sive and detailed research on toxicity pharmacodynamicspharmacokinetics and molecular mechanism are necessaryto be explored to develop its bioactive compounds as effectivedrugs

bioactive compounds owing to their antifungal and anti-inflammatory activities [37 38] In one study the essentialoils in Radix Bupleuri were extracted by steam distillationand solvent extraction and then analyzed by GCMS 78peaks were identified Among these peaks the major volatilecompounds were 3-methylbutanal (724) pentanal (574)hexanal (2011) furan-2-carbaldehyde (2523) and hep-tanal (1207) [39] However in another study the resultsshowed that E-2-heptanal furan 2-pentyl and E-2-nonenalwere some of the main compounds of the oil [40]

42 Triterpenoid Saponins Triterpenoid saponins are themain active components of Radix Bupleuri which exhibit abroad spectrum of biological and pharmacological effectsincluding analgesic immunomodulatory hepatoprotectiveimmunomodulatory anti-inflammatory antitumor andantiviral activities [3 41ndash43] Currently approximately 35saponins have been isolated from Radix Bupleuri (Figure 2)[44ndash54] Among them saikosaponins a c and d are themajor bioactive constituents found in Radix Bupleurihowever a variety of minor saikosaponins have also been

isolated [16] The cytotoxic and antiproliferative effects ofsaikosaponins a and d have been attracting much interest inrecent years [55] Additionally more information about theintimate relationship between the structural characterizationof saikosaponins and their cytotoxic evaluations is verynecessary

43 Polyacetylenes Four polyacetylene compounds fromRadix Bupleuri have been identified including (2Z8Z10E)-pentadecatriene-46-diyne-1-ol (36) (2Z8E10E)-pentadec-atriene-46-diyne-1-ol (37) (2Z8Z10E)-heptadecatriene-46-diyne-1-ol (38) and bupleurynol (39) (Figure 3) [56 57]

44 Flavonoids So far twelve flavonoids have been isolatedand identified from Radix Bupleuri including quercetin(40) isorhamnetin (41) isorhamnetin-3-O-glucoside (42)puerarin (43) rutin (44) narcissin (45) eugenin (46)saikochromeA (47) saikochromic acid (48) 741015840-dihydroxy-isoflavone-7-O-120573-D-glucoside (49) saikochromosideA (50)and saikoisoflavonoside A (51) (Figure 4) [58ndash63]

51 Anti-inflammatory Effects Radix Bupleuri has beenwidely used for the treatment of several types of chronicinflammatory diseases The crude polysaccharides(80mgkg) isolated from the roots of Bupleurum chinenseDC significantly attenuated lung injury by inhibiting thelevel of myeloperoxidase (MPO) tumor necrosis factor-120572(TNF-120572) and serum nitric oxide (NO) [66] Chun et alreported that saikosaponins from Radix Bupleuri exhibitedanti-inflammatory activity on inflammatory processesincluding inhibition of inflammatory exudation capillarypermeability inflammatory mediators release migrationof white cells connective tissue hyperplasia and a varietyof allergic inflammation [67] Ma et al was the first toshow that saikosaponins exerted anti-inflammatory activityon paw edema mainly via regulating the nicotinate andnicotinamide metabolism and arachidonic acid metabolism[5] Zhu et al found that saikosaponin a (SSa) exhibitedan inhibitory effect on proinflammatory cytokines inLPS-stimulated macrophages The mechanism of theseactions involved the regulation of MAPK and NF-120581B signalspathways [68] In another study SSa dose-dependentlyinhibited the production of ROS TNF-120572 IL-8 COX-2 andiNOS in LPS-stimulated human umbilical endothelial cells(HUVECs) by upregulating of the LXR120572-ABCA1 signalingpathway [69] Moreover Lee et al showed that saikosaponinc (SSc) was also shown to inhibited LPS-induced apoptosis inHUVECs via inhibition of caspase-3 activation and caspase-3-mediated-FAK degradation [70] Zhao et al showed thatSSa also suppressed TNF-120572 and IL-6 concentrations inthe intestines of septic rats through the inhibition of thenucleotide-binding oligomerization domain 2 (NOD2)NF-120581B signaling pathway [71] Saikosaponin d (SSd) has beenreported to inhibit PGE2 production and intracellular freeCa2+ concentration ([Ca2+]i) in a concentration-dependentmanner with an IC50 value of 3 120583m in C6 rat glioma cells[72]

In addition several studies showed that a widerange of Radix Bupleuri preparations also exhibited anti-inflammatory effects in in vitro and in vivo model Li et alshowed that Saireito and its active components (SSd) couldsuppress the proliferation of mesangial cells and expansionof the mesangial matrix in the rat glomerulonephritismodel [73] In experimental chronic pancreatitis rats modelldquoChai-hu-shu-gan powderrdquo exerted anti-inflammatory andantifibrotic effects by inhibiting the expression of nuclearfactor-120581B (NF-120581B) and TNF-120572 mRNA in the pancreas [74]Furthermore it also reduced the abnormally high plasmalevel of cholecystokinin improved the gastricmovement andavoided nausea and flatulence [75] In another experimenta Chinese herbal formula called ldquoRCM-101rdquo (containingFlos magnoliae Radix Bupleuri Radix Glycyrrhizae RadixAngelicae Sinensis etc) inhibited the NO production andiNOS protein expression in LPS-stimulated rat aorta andRaw 2647 macrophages [76]

52 Anticancer Effects The extracts and compounds ofRadix Bupleuri also possessed anticancerantitumor effectThe acetone extract of Bupleurum scorzonerifolium couldinhibit the proliferation of A549 human lung cancer cellsin a dose-dependent manner via causing cell cycle arrestin the G2M phase increasing microtubule stabilizationsuppressing telomerase activity activating ERK 12 andcaspase-39 in A549 cells [77ndash79] Saponins isolated fromRadix Bupleuri also exhibited significantly anti-proliferativeactivity in human non-small cell lung cancer A549 cellsthrough Fas-dependent apoptotic pathway [80] Su et alfound that thewater extracts ofRadix Bupleuri could enhance5-fluorouracil-induced cytotoxicity in HepG2 hepatoma cellsthrough cell arrest at the late G1early S phase while pro-tecting normal blood lymphocytes [6] SSd showed verypotent activity against the HepG2 cell line with an IC50value of 125mgml The mechanism of cytotoxicity was

Several Chinese medicine preparations containing RadixBupleuri also have been traditionally used in the treatmentof tumors and cancer The water extracts of ldquoLong DanXie Gan Wanrdquo exerted a significant growth inhibitory effectin HL60 and HT29 cancer cell lines indicating that thisformulation may possess some chemotherapeutic potential[83] Treatment with ldquoxiao-chai-hu decoctionrdquo exhibited asignificantly lower incidence of hepatocellular carcinoma andreductions in cancer pain and tumor size The underlyingmechanismof the antitumor activities is based on stimulationof the reticuloendothelial system (RES) and is closely relatedof TNF production [84ndash86]

53 Antiviral Effects Wen et al reported that the acetoneextract of Radix Bupleuri possessed a significant antiviruseffect on acute respiratory tract infections with H1N1 virusinfection and suppressed influenzaAvirus-inducedRANTESsecretion in H1N1-infected A549 cells at a concentration of

100 and 200120583gml suggesting that Radix Bupleuri might bebeneficial for the treatment of chronic inflammatory condi-tions followed by viral infection [10] SSc has been reportedto show effective anti-HBV activity through inhibiting DNAexpression of HBsAg HBeAg and HBV [81] Treatmentwith ldquoxiao-chai-hu decoctionrdquo (20120583gml 3 days 20120583gml6 days) could inhibit the production of HBV (119875 lt 00001)and the expression of HBeAg Moreover crude saponinsof Bupleurum chinense DC could inhibit the replication ofHBV (119875 lt 00001) [87] Similarly in another study Yinet al showed that SSd isolated from the MeOH extract ofBupleurum chinense DC exhibited significant bioactivity ininhibitingDNA replication ofHBV [88]The antiviral activityof saikosaponins (a b2 c and d) and their mode of actinwere examined The results showed that all saikosaponinsexerted antiviral activity on human coronavirus-229E atconcentrations of 025ndash25120583m and the strongest activity wasobserved for saikosaponin b2 with an IC50 of 17 120583m Thismechanism might involve interference in the early stage ofviral replication such as absorption and penetration of thevirus [89]

adjustment of synthesis and exudation of cyclic adenosinemonophosphate (cAMP) and arginine vasopressin (AVP)[90] A novel in situ gel system for nasal delivery of theessential oil from Radix Bupleuri was prepared The resultssuggested that Radix Bupleuri in situ gel can be moreeffective than the solution in the treatment of fever [91] Asimilar study showed that the essential oil extracted from the

herb exhibited dose-dependent antipyretic capacity on bothfevered rabbits and rats [92]

55 Antibacterial Effects The ethanol extract of Bupleu-rum chinense DC exerted a remarkable bacteriostaticeffect on Gram-negative microorganism Helicobacter pyloriThe bioactive minimum inhibitory concentration (MIC)

value was 60Mm [93] Saikosaponins isolated from RadixBupleuri have been reported to exhibit antibacterial activityparticularly against Pseudomonas aeruginosa and Listeriamonocytogenes The protective effect was attributed to theimmunomodulatory action on macrophages [94] ldquoChaihuinjectionrdquo has also been tested for possible antimicrobialactivity in vitroThe results demonstrated thatmild inhibitionof Staphylococcus aureus was observed but no effects wereobserved against Staphylococcus albusNeisseria gonorrhoeaeDiplococcus pneumoniae haemolytic Streptococcus or Pseu-domonas aeruginosa [95]

56 Hepatoprotective Effects The liver protective effectsagainst CCl4 induced liver injury were investigated aftertreatment ofmicewith raw and vinegar-bakedRadix Bupleuri(5 gkgday) for 14 days The results showed that both rawand processed Radix Bupleuri showed liver protective effectsagainst CCl4 induced liver injury and the vinegar-bakedRadix Bupleuri exerted better effects than that of raw RadixBupleuri [96] Pretreated with saikosaponins especially SSaor SSd showed remarkable inhibition of D-galactosamine-induced hepatic injury through decreasing the activity ofglucose-6-phosphatase and NADPH-cytochrome C reduc-tase and increasing 51015840-nucleotidase activity [97] Similarlybupleurosides III VI IX and XIII and saikosaponin b3isolated from Bupleurum scorzonerifolium Willd were alsofound to exhibit protective effect on the D-galactosamine-induced cytotoxicity in primary cultured rat hepatocytes[98] Further studies also demonstrated that the protectiveeffects of saikosaponins isolated from Bupleurum chinenseDC could prevent hepatocyte injury through regulatingintracellular calcium levels [99] In a rat model with CCl4induced acute hepatic injury the hepatic enzyme levels (GOTGPT and ALP) and the lipid peroxidation in the liver weresignificantly reduced by the administration of SSd [100]Additionally SSd significantly reduced collagen I depositionand alanine aminotransferase level on liver fibrosis rats anddecreased the concentration of transforming growth factor1205731 (TGF-1205731) Moreover SSd was able to alleviate hepatocyteinjury from oxidative stressThe effect of SSd on liver fibrosismay be related to its ability to reduce lipid peroxidation [101]

57 Immunomodulatory Effects Yamakage et al determinedthe effects of Radix Bupleuri on spontaneous lymphaticvessel activity The results indicated that Radix Bupleurisignificantly increased the amplitude of spontaneous activityof lymphatic vessels in a concentration-dependent mannerand the mechanisms of this effect seem to be independent ofendothelial function [102] Eugenin (46) and saikochrome A(47) isolated from the MeOH extracts from Bupleurum scor-zonerifolium possessed immunosuppressive effect on humanperipheral blood T cells via inhibiting CD28-costimulatedactivation [62] SSd (10mg intraperitoneally) significantlyactivated peritoneal macrophages in terms of enhancementof phagocytic activity increased level of cellular lysosomalenzyme and suppressed the response of plaque-forming cellsto heterologous erythrocytes by stimulating T and B cells ina dose-dependent manner [103] Moreover SSd modulated

lymphocyte activity through suppressing the T cell responseand increasing the B cell response to different mitogensand the interleukin- (IL-) 2IL-4 production through areceptor-bypassed pathway [41 104 105] In another exper-iment Wong et al found that SSd was shown to inhibitOKT3CD28-costimulated human T cell proliferation andPMA PMAionomycin and Con A-induced mouse T cellactivation in vitro The underlying mechanisms involveddownregulation of NF-kB signaling by suppression of IKKand Akt activities [106]

58 Autophagic Effect Autophagy is a complex processin cells which occurs through the formation of double-membrane vesicles (autophagosomes) which are engulfedby cytoplasmic molecules Then the autophagosome fuseswith the lysosomes leading to degradation of long-livedproteins aggregated proteins and damaged organelles [107ndash109] Moreover autophagy might be triggered by hypoxianutritional deprivation radiation chemical drugs and otherstimulants [110] Autophagy contributes to the pathogenesisof diverse diseases such as neuronal degeneration inflamma-tory bowel disease aging and cancer [111 112] In the previousstudy Law et al demonstrated that the protective pharma-cological effects of Radix Bupleuri might be attributed to itsautophagy inductionThe autophagic effect of Radix Bupleuriplayed an important role in relieving liver disease-relatedsymptoms through anti-inflammatory organ-protective andaggregate removal functions Furthermore the anticancereffects of Radix Bupleuri could be attributed to its autophagyinduction Radix Bupleuri has been found to be an effectivetreatment against depression by regulating metabolite hor-mone and neurotransmitter levels via autophagy-mediatedlipid metabolism [113]

59 Other Pharmacological Effects The effect of the ethanolextract from Radix Bupleuri on cytochrome 450 isoformactivities using a six-drug cocktail approach was evaluatedthe results demonstrated that Radix Bupleuri had stronginduction activity on the CYP2E1 CYP2D6 and CYP3A4which may lead to potential plant drug-drug interactions[114] Radix Bupleuri was shown to be the inhibitor of 120573-glucuronidase The inhibition rate of Radix Bupleuri extractsRB1 (high molecular weight polysaccharides) RB2 (ethanolsolublewater insoluble component) RB3 (extracted by n-butanol soluble in water) and RB4 (low molecular weightwater soluble parts) on the activity of 120573-glucuronidase wasfound to be 4515 3394 2494 and 3454 respectively[115] In pentylenetetrazol (PTZ) induced epilepsy ratsmodelSSa isolated fromRadix Bupleuri significantly reduced seizureseverity and duration while it markedly elevated seizurelatency and downregulated the cytokines expression of p-mTOR p-70S6K L-1120573 and TNF-120572 through inhibitingmTORsignaling pathway [116] He et al demonstrated that SSa obvi-ously reduced lipoprotein uptake to block foamcell formationand the expression of LOX-1 and CD36 boosted cholesterolefflux and the expression of ABCA1 and PPAR120574 throughinhibiting PI3KAktNF-120581BNLRP3 signaling pathway [117]

In another experiment SSc exerted a potent effect on induc-ing human umbilical vein endothelial cells (HUVECs) via-bility and growth Furthermore SSc also induced endothelialcells migration and capillary tube formation The underlyingmechanisms might be related to the gene expression oractivation of matrix metalloproteinase-2 (MMP-2) vascularendothelial growth factor (VEGF) and the p42p44mitogen-activated protein kinase (MAPK ERK) [118] In addition SScwas shown to exhibit inhibitory activities against Alzheimerrsquosdisease (AD) via suppressing the secretion ofA120573 peptides andabnormal tau hyperphosphorylation-mediated microtubuledepolymerization Moreover SSc suppressed A120573 peptide-induced brain endothelial apoptosis indicating that Sscmight be a novel therapeutic tool for treating human AD andother neurodegenerative diseases [119] It was shown by Liuet al for the first time that four polyacetylenes (36ndash39) fromRadix Bupleuri potently exhibited an antidepressant activityby inhibiting the reuptake of serotonin norepinephrine anddopamine The mechanism might be mediated by increasingthe level of monoamines particularly 5-HT andNE [56] Zhuet al suggested that SSa and SSd exhibited the anthelminticactivity against Dactylogyrus spp infecting goldfish Theeffective concentration (EC50) values for SSa and SSd were146 and 074mgminus1 respectively [120]

510 Summary of Pharmacological Effects Radix Bupleuripossesses awide spectrumof pharmacological effects includ-ing anti-inflammatory effect anticancer effect antiviraleffect antipyretic effect antibacterial effect hepatoprotectiveeffect and immunomodulatory effect (Table 3) Based onthese pharmacological effects we can conclude that theextracts and the compounds from this plant can preventor treat certain diseases such as cancer fever malariahepatitis and AD However there is not enough systemicdata of these chemical compounds and their pharmacologicaleffects Thus in the future the pharmacological effects andthe possible molecular mechanisms of the pharmacologicalactivities of Radix Bupleurimust be urgently explored on ourmodern understanding of these diseasesrsquo pathophysiologies

6 Toxicology

Radix Bupleuri has been used for thousands of years asan important traditional herb in China However the toxiceffects of Radix Bupleuri in clinical applications have beengradually reported Several studies have found that the liveris the main organ affected by toxicity particularly in long-term use Major symptoms of liver injury induced by RadixBupleuri included transaminase lifts hepatitis and jaundiceHowever liver functions can return to normal levels aftera specific period [121] Radix Bupleuri has been reportedto exhibit acute hepatitis and acute hepatic necrosis Themean total daily dose was 180 plusmn 335 g which was morethan the Chinese Pharmacopoeia recommended range of 3to 10 g [122] Moreover Radix Bupleuri had been implicatedinmultiple cases of acute hepatitis both as an ingredient aloneand within a particular formulation ldquoXiao-Chai-Hu-Tangrdquo(also known as Syo-Saiko-To in Japanese) [123] Lee et al

demonstrated that two Chinese herbal products containingRadix Bupleuri might increase their risks of liver injuryin HBV-infected patients However further mechanisticresearch on the hepatotoxicity of Radix Bupleuri in thepresence ofHBV infection is warranted [124] In addition theessential oil of Radix Bupleuri induced acute hepatotoxicitywith asynchronous state higher heart rate and fast breathing[125] The total saponins isolated from Radix Bupleuri couldalso cause evidently liver damage in dose-dependent mannermanifested as hepatocyte organic lesion and liver functionchanges as well as hepatocyte death [126]

7 Pharmacokinetics

A selective and sensitive LC-MSMS method was developedand validated for simultaneous determination of SSa b2 cand d in rat plasma afteroral administration of the ethanol-water (50 50 vv) extract of Radix Bupleuri for the firsttime The results demonstrated that SSa c and d wereabsorbed rapidly with 119879max less than 30min [127] In anotherpharmacokinetics experiment of rats Liu et al was the first todevelop an UPLC-PDA-MS method to determine the phar-macokinetics of four polyacetylenes after ig administrationof 95 ethanol extract of Radix Bupleuri The results showedthat compounds 36 and 38 were not detected in rat serumwhereas compounds 37 and 39 exerted a fast distributionphase followed by a relatively slow elimination phase (119905121199114ndash7 h) [56]

8 Future Perspectives and Conclusions

In traditional Chinese medicine Radix Bupleuri has longbeen used regulate the exterior and interiormetabolisms dis-perse evil heat from superficies sooth the liver and promoteyang and qi It has been widely used to treat various diseasesin China Japan Korea and other Asian countries for manycenturies A total of 74 compounds including essential oilstriterpenoid saponins polyacetylenes flavonoids lignansfatty acids and sterols have been isolated and identifiedfrom Radix Bupleuri [39ndash65] Pharmacological studies haverevealed that Radix Bupleuri possesses a variety of biologicaleffects including anti-inflammatory anticancer antiviralantipyretic antibacterial antiobesity immunomodulatoryhepatoprotective neuroprotective and autophagic effects[66ndash120] However there are some aspects that need to befurther investigated

Radix Bupleuri is an ingredient of many patent medicinesor prescriptions Although modern experiments have con-firmed that this drug alone exhibits multiple pharmacolog-ical activities it is important to investigate the molecularmechanisms of Radix Bupleuri combined with other herbsbased on traditional uses Furthermore the pharmacologicaleffects of only a few of the ingredients such as saikosaponinsflavonoids and the essential oils have been investigatedSome polyacetylenes lignans and sterols have not beensufficiently researched in terms of their pharmacologicaleffects Radix Bupleuri shows both hepatoprotection and

hepatotoxicity which appears to be contradictory This phe-nomenon is similar to that of PolygonummultiflorumThunb[128] Based on the literature the main reasons are likelythe administration dosage and delivery time High doses andlong-term drug delivery are more likely to result in livertoxicity whereas low doses and short-term drug deliverymight result in liver protection Therefore this issue needsfurther study

In conclusion this review summarized the traditionaluses botany phytochemistry pharmacology and toxicologyof Radix Bupleuri Moreover it has provided a new founda-tion for further research on its mechanism of action and thedevelopment of better therapeutic agents employing RadixBupleuri in the future It is anticipated that the comprehen-sive and detailed research on toxicity pharmacodynamicspharmacokinetics and molecular mechanism are necessaryto be explored to develop its bioactive compounds as effectivedrugs

bioactive compounds owing to their antifungal and anti-inflammatory activities [37 38] In one study the essentialoils in Radix Bupleuri were extracted by steam distillationand solvent extraction and then analyzed by GCMS 78peaks were identified Among these peaks the major volatilecompounds were 3-methylbutanal (724) pentanal (574)hexanal (2011) furan-2-carbaldehyde (2523) and hep-tanal (1207) [39] However in another study the resultsshowed that E-2-heptanal furan 2-pentyl and E-2-nonenalwere some of the main compounds of the oil [40]

42 Triterpenoid Saponins Triterpenoid saponins are themain active components of Radix Bupleuri which exhibit abroad spectrum of biological and pharmacological effectsincluding analgesic immunomodulatory hepatoprotectiveimmunomodulatory anti-inflammatory antitumor andantiviral activities [3 41ndash43] Currently approximately 35saponins have been isolated from Radix Bupleuri (Figure 2)[44ndash54] Among them saikosaponins a c and d are themajor bioactive constituents found in Radix Bupleurihowever a variety of minor saikosaponins have also been

isolated [16] The cytotoxic and antiproliferative effects ofsaikosaponins a and d have been attracting much interest inrecent years [55] Additionally more information about theintimate relationship between the structural characterizationof saikosaponins and their cytotoxic evaluations is verynecessary

43 Polyacetylenes Four polyacetylene compounds fromRadix Bupleuri have been identified including (2Z8Z10E)-pentadecatriene-46-diyne-1-ol (36) (2Z8E10E)-pentadec-atriene-46-diyne-1-ol (37) (2Z8Z10E)-heptadecatriene-46-diyne-1-ol (38) and bupleurynol (39) (Figure 3) [56 57]

44 Flavonoids So far twelve flavonoids have been isolatedand identified from Radix Bupleuri including quercetin(40) isorhamnetin (41) isorhamnetin-3-O-glucoside (42)puerarin (43) rutin (44) narcissin (45) eugenin (46)saikochromeA (47) saikochromic acid (48) 741015840-dihydroxy-isoflavone-7-O-120573-D-glucoside (49) saikochromosideA (50)and saikoisoflavonoside A (51) (Figure 4) [58ndash63]

51 Anti-inflammatory Effects Radix Bupleuri has beenwidely used for the treatment of several types of chronicinflammatory diseases The crude polysaccharides(80mgkg) isolated from the roots of Bupleurum chinenseDC significantly attenuated lung injury by inhibiting thelevel of myeloperoxidase (MPO) tumor necrosis factor-120572(TNF-120572) and serum nitric oxide (NO) [66] Chun et alreported that saikosaponins from Radix Bupleuri exhibitedanti-inflammatory activity on inflammatory processesincluding inhibition of inflammatory exudation capillarypermeability inflammatory mediators release migrationof white cells connective tissue hyperplasia and a varietyof allergic inflammation [67] Ma et al was the first toshow that saikosaponins exerted anti-inflammatory activityon paw edema mainly via regulating the nicotinate andnicotinamide metabolism and arachidonic acid metabolism[5] Zhu et al found that saikosaponin a (SSa) exhibitedan inhibitory effect on proinflammatory cytokines inLPS-stimulated macrophages The mechanism of theseactions involved the regulation of MAPK and NF-120581B signalspathways [68] In another study SSa dose-dependentlyinhibited the production of ROS TNF-120572 IL-8 COX-2 andiNOS in LPS-stimulated human umbilical endothelial cells(HUVECs) by upregulating of the LXR120572-ABCA1 signalingpathway [69] Moreover Lee et al showed that saikosaponinc (SSc) was also shown to inhibited LPS-induced apoptosis inHUVECs via inhibition of caspase-3 activation and caspase-3-mediated-FAK degradation [70] Zhao et al showed thatSSa also suppressed TNF-120572 and IL-6 concentrations inthe intestines of septic rats through the inhibition of thenucleotide-binding oligomerization domain 2 (NOD2)NF-120581B signaling pathway [71] Saikosaponin d (SSd) has beenreported to inhibit PGE2 production and intracellular freeCa2+ concentration ([Ca2+]i) in a concentration-dependentmanner with an IC50 value of 3 120583m in C6 rat glioma cells[72]

In addition several studies showed that a widerange of Radix Bupleuri preparations also exhibited anti-inflammatory effects in in vitro and in vivo model Li et alshowed that Saireito and its active components (SSd) couldsuppress the proliferation of mesangial cells and expansionof the mesangial matrix in the rat glomerulonephritismodel [73] In experimental chronic pancreatitis rats modelldquoChai-hu-shu-gan powderrdquo exerted anti-inflammatory andantifibrotic effects by inhibiting the expression of nuclearfactor-120581B (NF-120581B) and TNF-120572 mRNA in the pancreas [74]Furthermore it also reduced the abnormally high plasmalevel of cholecystokinin improved the gastricmovement andavoided nausea and flatulence [75] In another experimenta Chinese herbal formula called ldquoRCM-101rdquo (containingFlos magnoliae Radix Bupleuri Radix Glycyrrhizae RadixAngelicae Sinensis etc) inhibited the NO production andiNOS protein expression in LPS-stimulated rat aorta andRaw 2647 macrophages [76]

52 Anticancer Effects The extracts and compounds ofRadix Bupleuri also possessed anticancerantitumor effectThe acetone extract of Bupleurum scorzonerifolium couldinhibit the proliferation of A549 human lung cancer cellsin a dose-dependent manner via causing cell cycle arrestin the G2M phase increasing microtubule stabilizationsuppressing telomerase activity activating ERK 12 andcaspase-39 in A549 cells [77ndash79] Saponins isolated fromRadix Bupleuri also exhibited significantly anti-proliferativeactivity in human non-small cell lung cancer A549 cellsthrough Fas-dependent apoptotic pathway [80] Su et alfound that thewater extracts ofRadix Bupleuri could enhance5-fluorouracil-induced cytotoxicity in HepG2 hepatoma cellsthrough cell arrest at the late G1early S phase while pro-tecting normal blood lymphocytes [6] SSd showed verypotent activity against the HepG2 cell line with an IC50value of 125mgml The mechanism of cytotoxicity was

Several Chinese medicine preparations containing RadixBupleuri also have been traditionally used in the treatmentof tumors and cancer The water extracts of ldquoLong DanXie Gan Wanrdquo exerted a significant growth inhibitory effectin HL60 and HT29 cancer cell lines indicating that thisformulation may possess some chemotherapeutic potential[83] Treatment with ldquoxiao-chai-hu decoctionrdquo exhibited asignificantly lower incidence of hepatocellular carcinoma andreductions in cancer pain and tumor size The underlyingmechanismof the antitumor activities is based on stimulationof the reticuloendothelial system (RES) and is closely relatedof TNF production [84ndash86]

53 Antiviral Effects Wen et al reported that the acetoneextract of Radix Bupleuri possessed a significant antiviruseffect on acute respiratory tract infections with H1N1 virusinfection and suppressed influenzaAvirus-inducedRANTESsecretion in H1N1-infected A549 cells at a concentration of

100 and 200120583gml suggesting that Radix Bupleuri might bebeneficial for the treatment of chronic inflammatory condi-tions followed by viral infection [10] SSc has been reportedto show effective anti-HBV activity through inhibiting DNAexpression of HBsAg HBeAg and HBV [81] Treatmentwith ldquoxiao-chai-hu decoctionrdquo (20120583gml 3 days 20120583gml6 days) could inhibit the production of HBV (119875 lt 00001)and the expression of HBeAg Moreover crude saponinsof Bupleurum chinense DC could inhibit the replication ofHBV (119875 lt 00001) [87] Similarly in another study Yinet al showed that SSd isolated from the MeOH extract ofBupleurum chinense DC exhibited significant bioactivity ininhibitingDNA replication ofHBV [88]The antiviral activityof saikosaponins (a b2 c and d) and their mode of actinwere examined The results showed that all saikosaponinsexerted antiviral activity on human coronavirus-229E atconcentrations of 025ndash25120583m and the strongest activity wasobserved for saikosaponin b2 with an IC50 of 17 120583m Thismechanism might involve interference in the early stage ofviral replication such as absorption and penetration of thevirus [89]

56 Hepatoprotective Effects The liver protective effectsagainst CCl4 induced liver injury were investigated aftertreatment ofmicewith raw and vinegar-bakedRadix Bupleuri(5 gkgday) for 14 days The results showed that both rawand processed Radix Bupleuri showed liver protective effectsagainst CCl4 induced liver injury and the vinegar-bakedRadix Bupleuri exerted better effects than that of raw RadixBupleuri [96] Pretreated with saikosaponins especially SSaor SSd showed remarkable inhibition of D-galactosamine-induced hepatic injury through decreasing the activity ofglucose-6-phosphatase and NADPH-cytochrome C reduc-tase and increasing 51015840-nucleotidase activity [97] Similarlybupleurosides III VI IX and XIII and saikosaponin b3isolated from Bupleurum scorzonerifolium Willd were alsofound to exhibit protective effect on the D-galactosamine-induced cytotoxicity in primary cultured rat hepatocytes[98] Further studies also demonstrated that the protectiveeffects of saikosaponins isolated from Bupleurum chinenseDC could prevent hepatocyte injury through regulatingintracellular calcium levels [99] In a rat model with CCl4induced acute hepatic injury the hepatic enzyme levels (GOTGPT and ALP) and the lipid peroxidation in the liver weresignificantly reduced by the administration of SSd [100]Additionally SSd significantly reduced collagen I depositionand alanine aminotransferase level on liver fibrosis rats anddecreased the concentration of transforming growth factor1205731 (TGF-1205731) Moreover SSd was able to alleviate hepatocyteinjury from oxidative stressThe effect of SSd on liver fibrosismay be related to its ability to reduce lipid peroxidation [101]

57 Immunomodulatory Effects Yamakage et al determinedthe effects of Radix Bupleuri on spontaneous lymphaticvessel activity The results indicated that Radix Bupleurisignificantly increased the amplitude of spontaneous activityof lymphatic vessels in a concentration-dependent mannerand the mechanisms of this effect seem to be independent ofendothelial function [102] Eugenin (46) and saikochrome A(47) isolated from the MeOH extracts from Bupleurum scor-zonerifolium possessed immunosuppressive effect on humanperipheral blood T cells via inhibiting CD28-costimulatedactivation [62] SSd (10mg intraperitoneally) significantlyactivated peritoneal macrophages in terms of enhancementof phagocytic activity increased level of cellular lysosomalenzyme and suppressed the response of plaque-forming cellsto heterologous erythrocytes by stimulating T and B cells ina dose-dependent manner [103] Moreover SSd modulated

lymphocyte activity through suppressing the T cell responseand increasing the B cell response to different mitogensand the interleukin- (IL-) 2IL-4 production through areceptor-bypassed pathway [41 104 105] In another exper-iment Wong et al found that SSd was shown to inhibitOKT3CD28-costimulated human T cell proliferation andPMA PMAionomycin and Con A-induced mouse T cellactivation in vitro The underlying mechanisms involveddownregulation of NF-kB signaling by suppression of IKKand Akt activities [106]

58 Autophagic Effect Autophagy is a complex processin cells which occurs through the formation of double-membrane vesicles (autophagosomes) which are engulfedby cytoplasmic molecules Then the autophagosome fuseswith the lysosomes leading to degradation of long-livedproteins aggregated proteins and damaged organelles [107ndash109] Moreover autophagy might be triggered by hypoxianutritional deprivation radiation chemical drugs and otherstimulants [110] Autophagy contributes to the pathogenesisof diverse diseases such as neuronal degeneration inflamma-tory bowel disease aging and cancer [111 112] In the previousstudy Law et al demonstrated that the protective pharma-cological effects of Radix Bupleuri might be attributed to itsautophagy inductionThe autophagic effect of Radix Bupleuriplayed an important role in relieving liver disease-relatedsymptoms through anti-inflammatory organ-protective andaggregate removal functions Furthermore the anticancereffects of Radix Bupleuri could be attributed to its autophagyinduction Radix Bupleuri has been found to be an effectivetreatment against depression by regulating metabolite hor-mone and neurotransmitter levels via autophagy-mediatedlipid metabolism [113]

59 Other Pharmacological Effects The effect of the ethanolextract from Radix Bupleuri on cytochrome 450 isoformactivities using a six-drug cocktail approach was evaluatedthe results demonstrated that Radix Bupleuri had stronginduction activity on the CYP2E1 CYP2D6 and CYP3A4which may lead to potential plant drug-drug interactions[114] Radix Bupleuri was shown to be the inhibitor of 120573-glucuronidase The inhibition rate of Radix Bupleuri extractsRB1 (high molecular weight polysaccharides) RB2 (ethanolsolublewater insoluble component) RB3 (extracted by n-butanol soluble in water) and RB4 (low molecular weightwater soluble parts) on the activity of 120573-glucuronidase wasfound to be 4515 3394 2494 and 3454 respectively[115] In pentylenetetrazol (PTZ) induced epilepsy ratsmodelSSa isolated fromRadix Bupleuri significantly reduced seizureseverity and duration while it markedly elevated seizurelatency and downregulated the cytokines expression of p-mTOR p-70S6K L-1120573 and TNF-120572 through inhibitingmTORsignaling pathway [116] He et al demonstrated that SSa obvi-ously reduced lipoprotein uptake to block foamcell formationand the expression of LOX-1 and CD36 boosted cholesterolefflux and the expression of ABCA1 and PPAR120574 throughinhibiting PI3KAktNF-120581BNLRP3 signaling pathway [117]

In another experiment SSc exerted a potent effect on induc-ing human umbilical vein endothelial cells (HUVECs) via-bility and growth Furthermore SSc also induced endothelialcells migration and capillary tube formation The underlyingmechanisms might be related to the gene expression oractivation of matrix metalloproteinase-2 (MMP-2) vascularendothelial growth factor (VEGF) and the p42p44mitogen-activated protein kinase (MAPK ERK) [118] In addition SScwas shown to exhibit inhibitory activities against Alzheimerrsquosdisease (AD) via suppressing the secretion ofA120573 peptides andabnormal tau hyperphosphorylation-mediated microtubuledepolymerization Moreover SSc suppressed A120573 peptide-induced brain endothelial apoptosis indicating that Sscmight be a novel therapeutic tool for treating human AD andother neurodegenerative diseases [119] It was shown by Liuet al for the first time that four polyacetylenes (36ndash39) fromRadix Bupleuri potently exhibited an antidepressant activityby inhibiting the reuptake of serotonin norepinephrine anddopamine The mechanism might be mediated by increasingthe level of monoamines particularly 5-HT andNE [56] Zhuet al suggested that SSa and SSd exhibited the anthelminticactivity against Dactylogyrus spp infecting goldfish Theeffective concentration (EC50) values for SSa and SSd were146 and 074mgminus1 respectively [120]

510 Summary of Pharmacological Effects Radix Bupleuripossesses awide spectrumof pharmacological effects includ-ing anti-inflammatory effect anticancer effect antiviraleffect antipyretic effect antibacterial effect hepatoprotectiveeffect and immunomodulatory effect (Table 3) Based onthese pharmacological effects we can conclude that theextracts and the compounds from this plant can preventor treat certain diseases such as cancer fever malariahepatitis and AD However there is not enough systemicdata of these chemical compounds and their pharmacologicaleffects Thus in the future the pharmacological effects andthe possible molecular mechanisms of the pharmacologicalactivities of Radix Bupleurimust be urgently explored on ourmodern understanding of these diseasesrsquo pathophysiologies

6 Toxicology

Radix Bupleuri has been used for thousands of years asan important traditional herb in China However the toxiceffects of Radix Bupleuri in clinical applications have beengradually reported Several studies have found that the liveris the main organ affected by toxicity particularly in long-term use Major symptoms of liver injury induced by RadixBupleuri included transaminase lifts hepatitis and jaundiceHowever liver functions can return to normal levels aftera specific period [121] Radix Bupleuri has been reportedto exhibit acute hepatitis and acute hepatic necrosis Themean total daily dose was 180 plusmn 335 g which was morethan the Chinese Pharmacopoeia recommended range of 3to 10 g [122] Moreover Radix Bupleuri had been implicatedinmultiple cases of acute hepatitis both as an ingredient aloneand within a particular formulation ldquoXiao-Chai-Hu-Tangrdquo(also known as Syo-Saiko-To in Japanese) [123] Lee et al

demonstrated that two Chinese herbal products containingRadix Bupleuri might increase their risks of liver injuryin HBV-infected patients However further mechanisticresearch on the hepatotoxicity of Radix Bupleuri in thepresence ofHBV infection is warranted [124] In addition theessential oil of Radix Bupleuri induced acute hepatotoxicitywith asynchronous state higher heart rate and fast breathing[125] The total saponins isolated from Radix Bupleuri couldalso cause evidently liver damage in dose-dependent mannermanifested as hepatocyte organic lesion and liver functionchanges as well as hepatocyte death [126]

7 Pharmacokinetics

A selective and sensitive LC-MSMS method was developedand validated for simultaneous determination of SSa b2 cand d in rat plasma afteroral administration of the ethanol-water (50 50 vv) extract of Radix Bupleuri for the firsttime The results demonstrated that SSa c and d wereabsorbed rapidly with 119879max less than 30min [127] In anotherpharmacokinetics experiment of rats Liu et al was the first todevelop an UPLC-PDA-MS method to determine the phar-macokinetics of four polyacetylenes after ig administrationof 95 ethanol extract of Radix Bupleuri The results showedthat compounds 36 and 38 were not detected in rat serumwhereas compounds 37 and 39 exerted a fast distributionphase followed by a relatively slow elimination phase (119905121199114ndash7 h) [56]

8 Future Perspectives and Conclusions

In traditional Chinese medicine Radix Bupleuri has longbeen used regulate the exterior and interiormetabolisms dis-perse evil heat from superficies sooth the liver and promoteyang and qi It has been widely used to treat various diseasesin China Japan Korea and other Asian countries for manycenturies A total of 74 compounds including essential oilstriterpenoid saponins polyacetylenes flavonoids lignansfatty acids and sterols have been isolated and identifiedfrom Radix Bupleuri [39ndash65] Pharmacological studies haverevealed that Radix Bupleuri possesses a variety of biologicaleffects including anti-inflammatory anticancer antiviralantipyretic antibacterial antiobesity immunomodulatoryhepatoprotective neuroprotective and autophagic effects[66ndash120] However there are some aspects that need to befurther investigated

Radix Bupleuri is an ingredient of many patent medicinesor prescriptions Although modern experiments have con-firmed that this drug alone exhibits multiple pharmacolog-ical activities it is important to investigate the molecularmechanisms of Radix Bupleuri combined with other herbsbased on traditional uses Furthermore the pharmacologicaleffects of only a few of the ingredients such as saikosaponinsflavonoids and the essential oils have been investigatedSome polyacetylenes lignans and sterols have not beensufficiently researched in terms of their pharmacologicaleffects Radix Bupleuri shows both hepatoprotection and

hepatotoxicity which appears to be contradictory This phe-nomenon is similar to that of PolygonummultiflorumThunb[128] Based on the literature the main reasons are likelythe administration dosage and delivery time High doses andlong-term drug delivery are more likely to result in livertoxicity whereas low doses and short-term drug deliverymight result in liver protection Therefore this issue needsfurther study

In conclusion this review summarized the traditionaluses botany phytochemistry pharmacology and toxicologyof Radix Bupleuri Moreover it has provided a new founda-tion for further research on its mechanism of action and thedevelopment of better therapeutic agents employing RadixBupleuri in the future It is anticipated that the comprehen-sive and detailed research on toxicity pharmacodynamicspharmacokinetics and molecular mechanism are necessaryto be explored to develop its bioactive compounds as effectivedrugs

Several Chinese medicine preparations containing RadixBupleuri also have been traditionally used in the treatmentof tumors and cancer The water extracts of ldquoLong DanXie Gan Wanrdquo exerted a significant growth inhibitory effectin HL60 and HT29 cancer cell lines indicating that thisformulation may possess some chemotherapeutic potential[83] Treatment with ldquoxiao-chai-hu decoctionrdquo exhibited asignificantly lower incidence of hepatocellular carcinoma andreductions in cancer pain and tumor size The underlyingmechanismof the antitumor activities is based on stimulationof the reticuloendothelial system (RES) and is closely relatedof TNF production [84ndash86]

53 Antiviral Effects Wen et al reported that the acetoneextract of Radix Bupleuri possessed a significant antiviruseffect on acute respiratory tract infections with H1N1 virusinfection and suppressed influenzaAvirus-inducedRANTESsecretion in H1N1-infected A549 cells at a concentration of

100 and 200120583gml suggesting that Radix Bupleuri might bebeneficial for the treatment of chronic inflammatory condi-tions followed by viral infection [10] SSc has been reportedto show effective anti-HBV activity through inhibiting DNAexpression of HBsAg HBeAg and HBV [81] Treatmentwith ldquoxiao-chai-hu decoctionrdquo (20120583gml 3 days 20120583gml6 days) could inhibit the production of HBV (119875 lt 00001)and the expression of HBeAg Moreover crude saponinsof Bupleurum chinense DC could inhibit the replication ofHBV (119875 lt 00001) [87] Similarly in another study Yinet al showed that SSd isolated from the MeOH extract ofBupleurum chinense DC exhibited significant bioactivity ininhibitingDNA replication ofHBV [88]The antiviral activityof saikosaponins (a b2 c and d) and their mode of actinwere examined The results showed that all saikosaponinsexerted antiviral activity on human coronavirus-229E atconcentrations of 025ndash25120583m and the strongest activity wasobserved for saikosaponin b2 with an IC50 of 17 120583m Thismechanism might involve interference in the early stage ofviral replication such as absorption and penetration of thevirus [89]

value was 60Mm [93] Saikosaponins isolated from RadixBupleuri have been reported to exhibit antibacterial activityparticularly against Pseudomonas aeruginosa and Listeriamonocytogenes The protective effect was attributed to theimmunomodulatory action on macrophages [94] ldquoChaihuinjectionrdquo has also been tested for possible antimicrobialactivity in vitroThe results demonstrated thatmild inhibitionof Staphylococcus aureus was observed but no effects wereobserved against Staphylococcus albusNeisseria gonorrhoeaeDiplococcus pneumoniae haemolytic Streptococcus or Pseu-domonas aeruginosa [95]

56 Hepatoprotective Effects The liver protective effectsagainst CCl4 induced liver injury were investigated aftertreatment ofmicewith raw and vinegar-bakedRadix Bupleuri(5 gkgday) for 14 days The results showed that both rawand processed Radix Bupleuri showed liver protective effectsagainst CCl4 induced liver injury and the vinegar-bakedRadix Bupleuri exerted better effects than that of raw RadixBupleuri [96] Pretreated with saikosaponins especially SSaor SSd showed remarkable inhibition of D-galactosamine-induced hepatic injury through decreasing the activity ofglucose-6-phosphatase and NADPH-cytochrome C reduc-tase and increasing 51015840-nucleotidase activity [97] Similarlybupleurosides III VI IX and XIII and saikosaponin b3isolated from Bupleurum scorzonerifolium Willd were alsofound to exhibit protective effect on the D-galactosamine-induced cytotoxicity in primary cultured rat hepatocytes[98] Further studies also demonstrated that the protectiveeffects of saikosaponins isolated from Bupleurum chinenseDC could prevent hepatocyte injury through regulatingintracellular calcium levels [99] In a rat model with CCl4induced acute hepatic injury the hepatic enzyme levels (GOTGPT and ALP) and the lipid peroxidation in the liver weresignificantly reduced by the administration of SSd [100]Additionally SSd significantly reduced collagen I depositionand alanine aminotransferase level on liver fibrosis rats anddecreased the concentration of transforming growth factor1205731 (TGF-1205731) Moreover SSd was able to alleviate hepatocyteinjury from oxidative stressThe effect of SSd on liver fibrosismay be related to its ability to reduce lipid peroxidation [101]

57 Immunomodulatory Effects Yamakage et al determinedthe effects of Radix Bupleuri on spontaneous lymphaticvessel activity The results indicated that Radix Bupleurisignificantly increased the amplitude of spontaneous activityof lymphatic vessels in a concentration-dependent mannerand the mechanisms of this effect seem to be independent ofendothelial function [102] Eugenin (46) and saikochrome A(47) isolated from the MeOH extracts from Bupleurum scor-zonerifolium possessed immunosuppressive effect on humanperipheral blood T cells via inhibiting CD28-costimulatedactivation [62] SSd (10mg intraperitoneally) significantlyactivated peritoneal macrophages in terms of enhancementof phagocytic activity increased level of cellular lysosomalenzyme and suppressed the response of plaque-forming cellsto heterologous erythrocytes by stimulating T and B cells ina dose-dependent manner [103] Moreover SSd modulated

lymphocyte activity through suppressing the T cell responseand increasing the B cell response to different mitogensand the interleukin- (IL-) 2IL-4 production through areceptor-bypassed pathway [41 104 105] In another exper-iment Wong et al found that SSd was shown to inhibitOKT3CD28-costimulated human T cell proliferation andPMA PMAionomycin and Con A-induced mouse T cellactivation in vitro The underlying mechanisms involveddownregulation of NF-kB signaling by suppression of IKKand Akt activities [106]

58 Autophagic Effect Autophagy is a complex processin cells which occurs through the formation of double-membrane vesicles (autophagosomes) which are engulfedby cytoplasmic molecules Then the autophagosome fuseswith the lysosomes leading to degradation of long-livedproteins aggregated proteins and damaged organelles [107ndash109] Moreover autophagy might be triggered by hypoxianutritional deprivation radiation chemical drugs and otherstimulants [110] Autophagy contributes to the pathogenesisof diverse diseases such as neuronal degeneration inflamma-tory bowel disease aging and cancer [111 112] In the previousstudy Law et al demonstrated that the protective pharma-cological effects of Radix Bupleuri might be attributed to itsautophagy inductionThe autophagic effect of Radix Bupleuriplayed an important role in relieving liver disease-relatedsymptoms through anti-inflammatory organ-protective andaggregate removal functions Furthermore the anticancereffects of Radix Bupleuri could be attributed to its autophagyinduction Radix Bupleuri has been found to be an effectivetreatment against depression by regulating metabolite hor-mone and neurotransmitter levels via autophagy-mediatedlipid metabolism [113]

59 Other Pharmacological Effects The effect of the ethanolextract from Radix Bupleuri on cytochrome 450 isoformactivities using a six-drug cocktail approach was evaluatedthe results demonstrated that Radix Bupleuri had stronginduction activity on the CYP2E1 CYP2D6 and CYP3A4which may lead to potential plant drug-drug interactions[114] Radix Bupleuri was shown to be the inhibitor of 120573-glucuronidase The inhibition rate of Radix Bupleuri extractsRB1 (high molecular weight polysaccharides) RB2 (ethanolsolublewater insoluble component) RB3 (extracted by n-butanol soluble in water) and RB4 (low molecular weightwater soluble parts) on the activity of 120573-glucuronidase wasfound to be 4515 3394 2494 and 3454 respectively[115] In pentylenetetrazol (PTZ) induced epilepsy ratsmodelSSa isolated fromRadix Bupleuri significantly reduced seizureseverity and duration while it markedly elevated seizurelatency and downregulated the cytokines expression of p-mTOR p-70S6K L-1120573 and TNF-120572 through inhibitingmTORsignaling pathway [116] He et al demonstrated that SSa obvi-ously reduced lipoprotein uptake to block foamcell formationand the expression of LOX-1 and CD36 boosted cholesterolefflux and the expression of ABCA1 and PPAR120574 throughinhibiting PI3KAktNF-120581BNLRP3 signaling pathway [117]

In another experiment SSc exerted a potent effect on induc-ing human umbilical vein endothelial cells (HUVECs) via-bility and growth Furthermore SSc also induced endothelialcells migration and capillary tube formation The underlyingmechanisms might be related to the gene expression oractivation of matrix metalloproteinase-2 (MMP-2) vascularendothelial growth factor (VEGF) and the p42p44mitogen-activated protein kinase (MAPK ERK) [118] In addition SScwas shown to exhibit inhibitory activities against Alzheimerrsquosdisease (AD) via suppressing the secretion ofA120573 peptides andabnormal tau hyperphosphorylation-mediated microtubuledepolymerization Moreover SSc suppressed A120573 peptide-induced brain endothelial apoptosis indicating that Sscmight be a novel therapeutic tool for treating human AD andother neurodegenerative diseases [119] It was shown by Liuet al for the first time that four polyacetylenes (36ndash39) fromRadix Bupleuri potently exhibited an antidepressant activityby inhibiting the reuptake of serotonin norepinephrine anddopamine The mechanism might be mediated by increasingthe level of monoamines particularly 5-HT andNE [56] Zhuet al suggested that SSa and SSd exhibited the anthelminticactivity against Dactylogyrus spp infecting goldfish Theeffective concentration (EC50) values for SSa and SSd were146 and 074mgminus1 respectively [120]

510 Summary of Pharmacological Effects Radix Bupleuripossesses awide spectrumof pharmacological effects includ-ing anti-inflammatory effect anticancer effect antiviraleffect antipyretic effect antibacterial effect hepatoprotectiveeffect and immunomodulatory effect (Table 3) Based onthese pharmacological effects we can conclude that theextracts and the compounds from this plant can preventor treat certain diseases such as cancer fever malariahepatitis and AD However there is not enough systemicdata of these chemical compounds and their pharmacologicaleffects Thus in the future the pharmacological effects andthe possible molecular mechanisms of the pharmacologicalactivities of Radix Bupleurimust be urgently explored on ourmodern understanding of these diseasesrsquo pathophysiologies

demonstrated that two Chinese herbal products containingRadix Bupleuri might increase their risks of liver injuryin HBV-infected patients However further mechanisticresearch on the hepatotoxicity of Radix Bupleuri in thepresence ofHBV infection is warranted [124] In addition theessential oil of Radix Bupleuri induced acute hepatotoxicitywith asynchronous state higher heart rate and fast breathing[125] The total saponins isolated from Radix Bupleuri couldalso cause evidently liver damage in dose-dependent mannermanifested as hepatocyte organic lesion and liver functionchanges as well as hepatocyte death [126]

7 Pharmacokinetics

A selective and sensitive LC-MSMS method was developedand validated for simultaneous determination of SSa b2 cand d in rat plasma afteroral administration of the ethanol-water (50 50 vv) extract of Radix Bupleuri for the firsttime The results demonstrated that SSa c and d wereabsorbed rapidly with 119879max less than 30min [127] In anotherpharmacokinetics experiment of rats Liu et al was the first todevelop an UPLC-PDA-MS method to determine the phar-macokinetics of four polyacetylenes after ig administrationof 95 ethanol extract of Radix Bupleuri The results showedthat compounds 36 and 38 were not detected in rat serumwhereas compounds 37 and 39 exerted a fast distributionphase followed by a relatively slow elimination phase (119905121199114ndash7 h) [56]

8 Future Perspectives and Conclusions

In traditional Chinese medicine Radix Bupleuri has longbeen used regulate the exterior and interiormetabolisms dis-perse evil heat from superficies sooth the liver and promoteyang and qi It has been widely used to treat various diseasesin China Japan Korea and other Asian countries for manycenturies A total of 74 compounds including essential oilstriterpenoid saponins polyacetylenes flavonoids lignansfatty acids and sterols have been isolated and identifiedfrom Radix Bupleuri [39ndash65] Pharmacological studies haverevealed that Radix Bupleuri possesses a variety of biologicaleffects including anti-inflammatory anticancer antiviralantipyretic antibacterial antiobesity immunomodulatoryhepatoprotective neuroprotective and autophagic effects[66ndash120] However there are some aspects that need to befurther investigated

Radix Bupleuri is an ingredient of many patent medicinesor prescriptions Although modern experiments have con-firmed that this drug alone exhibits multiple pharmacolog-ical activities it is important to investigate the molecularmechanisms of Radix Bupleuri combined with other herbsbased on traditional uses Furthermore the pharmacologicaleffects of only a few of the ingredients such as saikosaponinsflavonoids and the essential oils have been investigatedSome polyacetylenes lignans and sterols have not beensufficiently researched in terms of their pharmacologicaleffects Radix Bupleuri shows both hepatoprotection and

hepatotoxicity which appears to be contradictory This phe-nomenon is similar to that of PolygonummultiflorumThunb[128] Based on the literature the main reasons are likelythe administration dosage and delivery time High doses andlong-term drug delivery are more likely to result in livertoxicity whereas low doses and short-term drug deliverymight result in liver protection Therefore this issue needsfurther study

In conclusion this review summarized the traditionaluses botany phytochemistry pharmacology and toxicologyof Radix Bupleuri Moreover it has provided a new founda-tion for further research on its mechanism of action and thedevelopment of better therapeutic agents employing RadixBupleuri in the future It is anticipated that the comprehen-sive and detailed research on toxicity pharmacodynamicspharmacokinetics and molecular mechanism are necessaryto be explored to develop its bioactive compounds as effectivedrugs

51 Anti-inflammatory Effects Radix Bupleuri has beenwidely used for the treatment of several types of chronicinflammatory diseases The crude polysaccharides(80mgkg) isolated from the roots of Bupleurum chinenseDC significantly attenuated lung injury by inhibiting thelevel of myeloperoxidase (MPO) tumor necrosis factor-120572(TNF-120572) and serum nitric oxide (NO) [66] Chun et alreported that saikosaponins from Radix Bupleuri exhibitedanti-inflammatory activity on inflammatory processesincluding inhibition of inflammatory exudation capillarypermeability inflammatory mediators release migrationof white cells connective tissue hyperplasia and a varietyof allergic inflammation [67] Ma et al was the first toshow that saikosaponins exerted anti-inflammatory activityon paw edema mainly via regulating the nicotinate andnicotinamide metabolism and arachidonic acid metabolism[5] Zhu et al found that saikosaponin a (SSa) exhibitedan inhibitory effect on proinflammatory cytokines inLPS-stimulated macrophages The mechanism of theseactions involved the regulation of MAPK and NF-120581B signalspathways [68] In another study SSa dose-dependentlyinhibited the production of ROS TNF-120572 IL-8 COX-2 andiNOS in LPS-stimulated human umbilical endothelial cells(HUVECs) by upregulating of the LXR120572-ABCA1 signalingpathway [69] Moreover Lee et al showed that saikosaponinc (SSc) was also shown to inhibited LPS-induced apoptosis inHUVECs via inhibition of caspase-3 activation and caspase-3-mediated-FAK degradation [70] Zhao et al showed thatSSa also suppressed TNF-120572 and IL-6 concentrations inthe intestines of septic rats through the inhibition of thenucleotide-binding oligomerization domain 2 (NOD2)NF-120581B signaling pathway [71] Saikosaponin d (SSd) has beenreported to inhibit PGE2 production and intracellular freeCa2+ concentration ([Ca2+]i) in a concentration-dependentmanner with an IC50 value of 3 120583m in C6 rat glioma cells[72]

In addition several studies showed that a widerange of Radix Bupleuri preparations also exhibited anti-inflammatory effects in in vitro and in vivo model Li et alshowed that Saireito and its active components (SSd) couldsuppress the proliferation of mesangial cells and expansionof the mesangial matrix in the rat glomerulonephritismodel [73] In experimental chronic pancreatitis rats modelldquoChai-hu-shu-gan powderrdquo exerted anti-inflammatory andantifibrotic effects by inhibiting the expression of nuclearfactor-120581B (NF-120581B) and TNF-120572 mRNA in the pancreas [74]Furthermore it also reduced the abnormally high plasmalevel of cholecystokinin improved the gastricmovement andavoided nausea and flatulence [75] In another experimenta Chinese herbal formula called ldquoRCM-101rdquo (containingFlos magnoliae Radix Bupleuri Radix Glycyrrhizae RadixAngelicae Sinensis etc) inhibited the NO production andiNOS protein expression in LPS-stimulated rat aorta andRaw 2647 macrophages [76]

52 Anticancer Effects The extracts and compounds ofRadix Bupleuri also possessed anticancerantitumor effectThe acetone extract of Bupleurum scorzonerifolium couldinhibit the proliferation of A549 human lung cancer cellsin a dose-dependent manner via causing cell cycle arrestin the G2M phase increasing microtubule stabilizationsuppressing telomerase activity activating ERK 12 andcaspase-39 in A549 cells [77ndash79] Saponins isolated fromRadix Bupleuri also exhibited significantly anti-proliferativeactivity in human non-small cell lung cancer A549 cellsthrough Fas-dependent apoptotic pathway [80] Su et alfound that thewater extracts ofRadix Bupleuri could enhance5-fluorouracil-induced cytotoxicity in HepG2 hepatoma cellsthrough cell arrest at the late G1early S phase while pro-tecting normal blood lymphocytes [6] SSd showed verypotent activity against the HepG2 cell line with an IC50value of 125mgml The mechanism of cytotoxicity was

Several Chinese medicine preparations containing RadixBupleuri also have been traditionally used in the treatmentof tumors and cancer The water extracts of ldquoLong DanXie Gan Wanrdquo exerted a significant growth inhibitory effectin HL60 and HT29 cancer cell lines indicating that thisformulation may possess some chemotherapeutic potential[83] Treatment with ldquoxiao-chai-hu decoctionrdquo exhibited asignificantly lower incidence of hepatocellular carcinoma andreductions in cancer pain and tumor size The underlyingmechanismof the antitumor activities is based on stimulationof the reticuloendothelial system (RES) and is closely relatedof TNF production [84ndash86]

53 Antiviral Effects Wen et al reported that the acetoneextract of Radix Bupleuri possessed a significant antiviruseffect on acute respiratory tract infections with H1N1 virusinfection and suppressed influenzaAvirus-inducedRANTESsecretion in H1N1-infected A549 cells at a concentration of

100 and 200120583gml suggesting that Radix Bupleuri might bebeneficial for the treatment of chronic inflammatory condi-tions followed by viral infection [10] SSc has been reportedto show effective anti-HBV activity through inhibiting DNAexpression of HBsAg HBeAg and HBV [81] Treatmentwith ldquoxiao-chai-hu decoctionrdquo (20120583gml 3 days 20120583gml6 days) could inhibit the production of HBV (119875 lt 00001)and the expression of HBeAg Moreover crude saponinsof Bupleurum chinense DC could inhibit the replication ofHBV (119875 lt 00001) [87] Similarly in another study Yinet al showed that SSd isolated from the MeOH extract ofBupleurum chinense DC exhibited significant bioactivity ininhibitingDNA replication ofHBV [88]The antiviral activityof saikosaponins (a b2 c and d) and their mode of actinwere examined The results showed that all saikosaponinsexerted antiviral activity on human coronavirus-229E atconcentrations of 025ndash25120583m and the strongest activity wasobserved for saikosaponin b2 with an IC50 of 17 120583m Thismechanism might involve interference in the early stage ofviral replication such as absorption and penetration of thevirus [89]

herb exhibited dose-dependent antipyretic capacity on bothfevered rabbits and rats [92]

55 Antibacterial Effects The ethanol extract of Bupleu-rum chinense DC exerted a remarkable bacteriostaticeffect on Gram-negative microorganism Helicobacter pyloriThe bioactive minimum inhibitory concentration (MIC)

value was 60Mm [93] Saikosaponins isolated from RadixBupleuri have been reported to exhibit antibacterial activityparticularly against Pseudomonas aeruginosa and Listeriamonocytogenes The protective effect was attributed to theimmunomodulatory action on macrophages [94] ldquoChaihuinjectionrdquo has also been tested for possible antimicrobialactivity in vitroThe results demonstrated thatmild inhibitionof Staphylococcus aureus was observed but no effects wereobserved against Staphylococcus albusNeisseria gonorrhoeaeDiplococcus pneumoniae haemolytic Streptococcus or Pseu-domonas aeruginosa [95]

56 Hepatoprotective Effects The liver protective effectsagainst CCl4 induced liver injury were investigated aftertreatment ofmicewith raw and vinegar-bakedRadix Bupleuri(5 gkgday) for 14 days The results showed that both rawand processed Radix Bupleuri showed liver protective effectsagainst CCl4 induced liver injury and the vinegar-bakedRadix Bupleuri exerted better effects than that of raw RadixBupleuri [96] Pretreated with saikosaponins especially SSaor SSd showed remarkable inhibition of D-galactosamine-induced hepatic injury through decreasing the activity ofglucose-6-phosphatase and NADPH-cytochrome C reduc-tase and increasing 51015840-nucleotidase activity [97] Similarlybupleurosides III VI IX and XIII and saikosaponin b3isolated from Bupleurum scorzonerifolium Willd were alsofound to exhibit protective effect on the D-galactosamine-induced cytotoxicity in primary cultured rat hepatocytes[98] Further studies also demonstrated that the protectiveeffects of saikosaponins isolated from Bupleurum chinenseDC could prevent hepatocyte injury through regulatingintracellular calcium levels [99] In a rat model with CCl4induced acute hepatic injury the hepatic enzyme levels (GOTGPT and ALP) and the lipid peroxidation in the liver weresignificantly reduced by the administration of SSd [100]Additionally SSd significantly reduced collagen I depositionand alanine aminotransferase level on liver fibrosis rats anddecreased the concentration of transforming growth factor1205731 (TGF-1205731) Moreover SSd was able to alleviate hepatocyteinjury from oxidative stressThe effect of SSd on liver fibrosismay be related to its ability to reduce lipid peroxidation [101]

57 Immunomodulatory Effects Yamakage et al determinedthe effects of Radix Bupleuri on spontaneous lymphaticvessel activity The results indicated that Radix Bupleurisignificantly increased the amplitude of spontaneous activityof lymphatic vessels in a concentration-dependent mannerand the mechanisms of this effect seem to be independent ofendothelial function [102] Eugenin (46) and saikochrome A(47) isolated from the MeOH extracts from Bupleurum scor-zonerifolium possessed immunosuppressive effect on humanperipheral blood T cells via inhibiting CD28-costimulatedactivation [62] SSd (10mg intraperitoneally) significantlyactivated peritoneal macrophages in terms of enhancementof phagocytic activity increased level of cellular lysosomalenzyme and suppressed the response of plaque-forming cellsto heterologous erythrocytes by stimulating T and B cells ina dose-dependent manner [103] Moreover SSd modulated

lymphocyte activity through suppressing the T cell responseand increasing the B cell response to different mitogensand the interleukin- (IL-) 2IL-4 production through areceptor-bypassed pathway [41 104 105] In another exper-iment Wong et al found that SSd was shown to inhibitOKT3CD28-costimulated human T cell proliferation andPMA PMAionomycin and Con A-induced mouse T cellactivation in vitro The underlying mechanisms involveddownregulation of NF-kB signaling by suppression of IKKand Akt activities [106]

58 Autophagic Effect Autophagy is a complex processin cells which occurs through the formation of double-membrane vesicles (autophagosomes) which are engulfedby cytoplasmic molecules Then the autophagosome fuseswith the lysosomes leading to degradation of long-livedproteins aggregated proteins and damaged organelles [107ndash109] Moreover autophagy might be triggered by hypoxianutritional deprivation radiation chemical drugs and otherstimulants [110] Autophagy contributes to the pathogenesisof diverse diseases such as neuronal degeneration inflamma-tory bowel disease aging and cancer [111 112] In the previousstudy Law et al demonstrated that the protective pharma-cological effects of Radix Bupleuri might be attributed to itsautophagy inductionThe autophagic effect of Radix Bupleuriplayed an important role in relieving liver disease-relatedsymptoms through anti-inflammatory organ-protective andaggregate removal functions Furthermore the anticancereffects of Radix Bupleuri could be attributed to its autophagyinduction Radix Bupleuri has been found to be an effectivetreatment against depression by regulating metabolite hor-mone and neurotransmitter levels via autophagy-mediatedlipid metabolism [113]

59 Other Pharmacological Effects The effect of the ethanolextract from Radix Bupleuri on cytochrome 450 isoformactivities using a six-drug cocktail approach was evaluatedthe results demonstrated that Radix Bupleuri had stronginduction activity on the CYP2E1 CYP2D6 and CYP3A4which may lead to potential plant drug-drug interactions[114] Radix Bupleuri was shown to be the inhibitor of 120573-glucuronidase The inhibition rate of Radix Bupleuri extractsRB1 (high molecular weight polysaccharides) RB2 (ethanolsolublewater insoluble component) RB3 (extracted by n-butanol soluble in water) and RB4 (low molecular weightwater soluble parts) on the activity of 120573-glucuronidase wasfound to be 4515 3394 2494 and 3454 respectively[115] In pentylenetetrazol (PTZ) induced epilepsy ratsmodelSSa isolated fromRadix Bupleuri significantly reduced seizureseverity and duration while it markedly elevated seizurelatency and downregulated the cytokines expression of p-mTOR p-70S6K L-1120573 and TNF-120572 through inhibitingmTORsignaling pathway [116] He et al demonstrated that SSa obvi-ously reduced lipoprotein uptake to block foamcell formationand the expression of LOX-1 and CD36 boosted cholesterolefflux and the expression of ABCA1 and PPAR120574 throughinhibiting PI3KAktNF-120581BNLRP3 signaling pathway [117]

In another experiment SSc exerted a potent effect on induc-ing human umbilical vein endothelial cells (HUVECs) via-bility and growth Furthermore SSc also induced endothelialcells migration and capillary tube formation The underlyingmechanisms might be related to the gene expression oractivation of matrix metalloproteinase-2 (MMP-2) vascularendothelial growth factor (VEGF) and the p42p44mitogen-activated protein kinase (MAPK ERK) [118] In addition SScwas shown to exhibit inhibitory activities against Alzheimerrsquosdisease (AD) via suppressing the secretion ofA120573 peptides andabnormal tau hyperphosphorylation-mediated microtubuledepolymerization Moreover SSc suppressed A120573 peptide-induced brain endothelial apoptosis indicating that Sscmight be a novel therapeutic tool for treating human AD andother neurodegenerative diseases [119] It was shown by Liuet al for the first time that four polyacetylenes (36ndash39) fromRadix Bupleuri potently exhibited an antidepressant activityby inhibiting the reuptake of serotonin norepinephrine anddopamine The mechanism might be mediated by increasingthe level of monoamines particularly 5-HT andNE [56] Zhuet al suggested that SSa and SSd exhibited the anthelminticactivity against Dactylogyrus spp infecting goldfish Theeffective concentration (EC50) values for SSa and SSd were146 and 074mgminus1 respectively [120]

510 Summary of Pharmacological Effects Radix Bupleuripossesses awide spectrumof pharmacological effects includ-ing anti-inflammatory effect anticancer effect antiviraleffect antipyretic effect antibacterial effect hepatoprotectiveeffect and immunomodulatory effect (Table 3) Based onthese pharmacological effects we can conclude that theextracts and the compounds from this plant can preventor treat certain diseases such as cancer fever malariahepatitis and AD However there is not enough systemicdata of these chemical compounds and their pharmacologicaleffects Thus in the future the pharmacological effects andthe possible molecular mechanisms of the pharmacologicalactivities of Radix Bupleurimust be urgently explored on ourmodern understanding of these diseasesrsquo pathophysiologies

6 Toxicology

Radix Bupleuri has been used for thousands of years asan important traditional herb in China However the toxiceffects of Radix Bupleuri in clinical applications have beengradually reported Several studies have found that the liveris the main organ affected by toxicity particularly in long-term use Major symptoms of liver injury induced by RadixBupleuri included transaminase lifts hepatitis and jaundiceHowever liver functions can return to normal levels aftera specific period [121] Radix Bupleuri has been reportedto exhibit acute hepatitis and acute hepatic necrosis Themean total daily dose was 180 plusmn 335 g which was morethan the Chinese Pharmacopoeia recommended range of 3to 10 g [122] Moreover Radix Bupleuri had been implicatedinmultiple cases of acute hepatitis both as an ingredient aloneand within a particular formulation ldquoXiao-Chai-Hu-Tangrdquo(also known as Syo-Saiko-To in Japanese) [123] Lee et al

demonstrated that two Chinese herbal products containingRadix Bupleuri might increase their risks of liver injuryin HBV-infected patients However further mechanisticresearch on the hepatotoxicity of Radix Bupleuri in thepresence ofHBV infection is warranted [124] In addition theessential oil of Radix Bupleuri induced acute hepatotoxicitywith asynchronous state higher heart rate and fast breathing[125] The total saponins isolated from Radix Bupleuri couldalso cause evidently liver damage in dose-dependent mannermanifested as hepatocyte organic lesion and liver functionchanges as well as hepatocyte death [126]

7 Pharmacokinetics

A selective and sensitive LC-MSMS method was developedand validated for simultaneous determination of SSa b2 cand d in rat plasma afteroral administration of the ethanol-water (50 50 vv) extract of Radix Bupleuri for the firsttime The results demonstrated that SSa c and d wereabsorbed rapidly with 119879max less than 30min [127] In anotherpharmacokinetics experiment of rats Liu et al was the first todevelop an UPLC-PDA-MS method to determine the phar-macokinetics of four polyacetylenes after ig administrationof 95 ethanol extract of Radix Bupleuri The results showedthat compounds 36 and 38 were not detected in rat serumwhereas compounds 37 and 39 exerted a fast distributionphase followed by a relatively slow elimination phase (119905121199114ndash7 h) [56]

8 Future Perspectives and Conclusions

In traditional Chinese medicine Radix Bupleuri has longbeen used regulate the exterior and interiormetabolisms dis-perse evil heat from superficies sooth the liver and promoteyang and qi It has been widely used to treat various diseasesin China Japan Korea and other Asian countries for manycenturies A total of 74 compounds including essential oilstriterpenoid saponins polyacetylenes flavonoids lignansfatty acids and sterols have been isolated and identifiedfrom Radix Bupleuri [39ndash65] Pharmacological studies haverevealed that Radix Bupleuri possesses a variety of biologicaleffects including anti-inflammatory anticancer antiviralantipyretic antibacterial antiobesity immunomodulatoryhepatoprotective neuroprotective and autophagic effects[66ndash120] However there are some aspects that need to befurther investigated

Radix Bupleuri is an ingredient of many patent medicinesor prescriptions Although modern experiments have con-firmed that this drug alone exhibits multiple pharmacolog-ical activities it is important to investigate the molecularmechanisms of Radix Bupleuri combined with other herbsbased on traditional uses Furthermore the pharmacologicaleffects of only a few of the ingredients such as saikosaponinsflavonoids and the essential oils have been investigatedSome polyacetylenes lignans and sterols have not beensufficiently researched in terms of their pharmacologicaleffects Radix Bupleuri shows both hepatoprotection and

hepatotoxicity which appears to be contradictory This phe-nomenon is similar to that of PolygonummultiflorumThunb[128] Based on the literature the main reasons are likelythe administration dosage and delivery time High doses andlong-term drug delivery are more likely to result in livertoxicity whereas low doses and short-term drug deliverymight result in liver protection Therefore this issue needsfurther study

In conclusion this review summarized the traditionaluses botany phytochemistry pharmacology and toxicologyof Radix Bupleuri Moreover it has provided a new founda-tion for further research on its mechanism of action and thedevelopment of better therapeutic agents employing RadixBupleuri in the future It is anticipated that the comprehen-sive and detailed research on toxicity pharmacodynamicspharmacokinetics and molecular mechanism are necessaryto be explored to develop its bioactive compounds as effectivedrugs

51 Anti-inflammatory Effects Radix Bupleuri has beenwidely used for the treatment of several types of chronicinflammatory diseases The crude polysaccharides(80mgkg) isolated from the roots of Bupleurum chinenseDC significantly attenuated lung injury by inhibiting thelevel of myeloperoxidase (MPO) tumor necrosis factor-120572(TNF-120572) and serum nitric oxide (NO) [66] Chun et alreported that saikosaponins from Radix Bupleuri exhibitedanti-inflammatory activity on inflammatory processesincluding inhibition of inflammatory exudation capillarypermeability inflammatory mediators release migrationof white cells connective tissue hyperplasia and a varietyof allergic inflammation [67] Ma et al was the first toshow that saikosaponins exerted anti-inflammatory activityon paw edema mainly via regulating the nicotinate andnicotinamide metabolism and arachidonic acid metabolism[5] Zhu et al found that saikosaponin a (SSa) exhibitedan inhibitory effect on proinflammatory cytokines inLPS-stimulated macrophages The mechanism of theseactions involved the regulation of MAPK and NF-120581B signalspathways [68] In another study SSa dose-dependentlyinhibited the production of ROS TNF-120572 IL-8 COX-2 andiNOS in LPS-stimulated human umbilical endothelial cells(HUVECs) by upregulating of the LXR120572-ABCA1 signalingpathway [69] Moreover Lee et al showed that saikosaponinc (SSc) was also shown to inhibited LPS-induced apoptosis inHUVECs via inhibition of caspase-3 activation and caspase-3-mediated-FAK degradation [70] Zhao et al showed thatSSa also suppressed TNF-120572 and IL-6 concentrations inthe intestines of septic rats through the inhibition of thenucleotide-binding oligomerization domain 2 (NOD2)NF-120581B signaling pathway [71] Saikosaponin d (SSd) has beenreported to inhibit PGE2 production and intracellular freeCa2+ concentration ([Ca2+]i) in a concentration-dependentmanner with an IC50 value of 3 120583m in C6 rat glioma cells[72]

In addition several studies showed that a widerange of Radix Bupleuri preparations also exhibited anti-inflammatory effects in in vitro and in vivo model Li et alshowed that Saireito and its active components (SSd) couldsuppress the proliferation of mesangial cells and expansionof the mesangial matrix in the rat glomerulonephritismodel [73] In experimental chronic pancreatitis rats modelldquoChai-hu-shu-gan powderrdquo exerted anti-inflammatory andantifibrotic effects by inhibiting the expression of nuclearfactor-120581B (NF-120581B) and TNF-120572 mRNA in the pancreas [74]Furthermore it also reduced the abnormally high plasmalevel of cholecystokinin improved the gastricmovement andavoided nausea and flatulence [75] In another experimenta Chinese herbal formula called ldquoRCM-101rdquo (containingFlos magnoliae Radix Bupleuri Radix Glycyrrhizae RadixAngelicae Sinensis etc) inhibited the NO production andiNOS protein expression in LPS-stimulated rat aorta andRaw 2647 macrophages [76]

52 Anticancer Effects The extracts and compounds ofRadix Bupleuri also possessed anticancerantitumor effectThe acetone extract of Bupleurum scorzonerifolium couldinhibit the proliferation of A549 human lung cancer cellsin a dose-dependent manner via causing cell cycle arrestin the G2M phase increasing microtubule stabilizationsuppressing telomerase activity activating ERK 12 andcaspase-39 in A549 cells [77ndash79] Saponins isolated fromRadix Bupleuri also exhibited significantly anti-proliferativeactivity in human non-small cell lung cancer A549 cellsthrough Fas-dependent apoptotic pathway [80] Su et alfound that thewater extracts ofRadix Bupleuri could enhance5-fluorouracil-induced cytotoxicity in HepG2 hepatoma cellsthrough cell arrest at the late G1early S phase while pro-tecting normal blood lymphocytes [6] SSd showed verypotent activity against the HepG2 cell line with an IC50value of 125mgml The mechanism of cytotoxicity was

Several Chinese medicine preparations containing RadixBupleuri also have been traditionally used in the treatmentof tumors and cancer The water extracts of ldquoLong DanXie Gan Wanrdquo exerted a significant growth inhibitory effectin HL60 and HT29 cancer cell lines indicating that thisformulation may possess some chemotherapeutic potential[83] Treatment with ldquoxiao-chai-hu decoctionrdquo exhibited asignificantly lower incidence of hepatocellular carcinoma andreductions in cancer pain and tumor size The underlyingmechanismof the antitumor activities is based on stimulationof the reticuloendothelial system (RES) and is closely relatedof TNF production [84ndash86]

53 Antiviral Effects Wen et al reported that the acetoneextract of Radix Bupleuri possessed a significant antiviruseffect on acute respiratory tract infections with H1N1 virusinfection and suppressed influenzaAvirus-inducedRANTESsecretion in H1N1-infected A549 cells at a concentration of

100 and 200120583gml suggesting that Radix Bupleuri might bebeneficial for the treatment of chronic inflammatory condi-tions followed by viral infection [10] SSc has been reportedto show effective anti-HBV activity through inhibiting DNAexpression of HBsAg HBeAg and HBV [81] Treatmentwith ldquoxiao-chai-hu decoctionrdquo (20120583gml 3 days 20120583gml6 days) could inhibit the production of HBV (119875 lt 00001)and the expression of HBeAg Moreover crude saponinsof Bupleurum chinense DC could inhibit the replication ofHBV (119875 lt 00001) [87] Similarly in another study Yinet al showed that SSd isolated from the MeOH extract ofBupleurum chinense DC exhibited significant bioactivity ininhibitingDNA replication ofHBV [88]The antiviral activityof saikosaponins (a b2 c and d) and their mode of actinwere examined The results showed that all saikosaponinsexerted antiviral activity on human coronavirus-229E atconcentrations of 025ndash25120583m and the strongest activity wasobserved for saikosaponin b2 with an IC50 of 17 120583m Thismechanism might involve interference in the early stage ofviral replication such as absorption and penetration of thevirus [89]

54 Antipyretic Effects The water extract of Radix Bupleuriwas reported to exert its antipyretic effect on dry yeast-induced high fever rats The mechanism is related to the

adjustment of synthesis and exudation of cyclic adenosinemonophosphate (cAMP) and arginine vasopressin (AVP)[90] A novel in situ gel system for nasal delivery of theessential oil from Radix Bupleuri was prepared The resultssuggested that Radix Bupleuri in situ gel can be moreeffective than the solution in the treatment of fever [91] Asimilar study showed that the essential oil extracted from the

herb exhibited dose-dependent antipyretic capacity on bothfevered rabbits and rats [92]

55 Antibacterial Effects The ethanol extract of Bupleu-rum chinense DC exerted a remarkable bacteriostaticeffect on Gram-negative microorganism Helicobacter pyloriThe bioactive minimum inhibitory concentration (MIC)

value was 60Mm [93] Saikosaponins isolated from RadixBupleuri have been reported to exhibit antibacterial activityparticularly against Pseudomonas aeruginosa and Listeriamonocytogenes The protective effect was attributed to theimmunomodulatory action on macrophages [94] ldquoChaihuinjectionrdquo has also been tested for possible antimicrobialactivity in vitroThe results demonstrated thatmild inhibitionof Staphylococcus aureus was observed but no effects wereobserved against Staphylococcus albusNeisseria gonorrhoeaeDiplococcus pneumoniae haemolytic Streptococcus or Pseu-domonas aeruginosa [95]

56 Hepatoprotective Effects The liver protective effectsagainst CCl4 induced liver injury were investigated aftertreatment ofmicewith raw and vinegar-bakedRadix Bupleuri(5 gkgday) for 14 days The results showed that both rawand processed Radix Bupleuri showed liver protective effectsagainst CCl4 induced liver injury and the vinegar-bakedRadix Bupleuri exerted better effects than that of raw RadixBupleuri [96] Pretreated with saikosaponins especially SSaor SSd showed remarkable inhibition of D-galactosamine-induced hepatic injury through decreasing the activity ofglucose-6-phosphatase and NADPH-cytochrome C reduc-tase and increasing 51015840-nucleotidase activity [97] Similarlybupleurosides III VI IX and XIII and saikosaponin b3isolated from Bupleurum scorzonerifolium Willd were alsofound to exhibit protective effect on the D-galactosamine-induced cytotoxicity in primary cultured rat hepatocytes[98] Further studies also demonstrated that the protectiveeffects of saikosaponins isolated from Bupleurum chinenseDC could prevent hepatocyte injury through regulatingintracellular calcium levels [99] In a rat model with CCl4induced acute hepatic injury the hepatic enzyme levels (GOTGPT and ALP) and the lipid peroxidation in the liver weresignificantly reduced by the administration of SSd [100]Additionally SSd significantly reduced collagen I depositionand alanine aminotransferase level on liver fibrosis rats anddecreased the concentration of transforming growth factor1205731 (TGF-1205731) Moreover SSd was able to alleviate hepatocyteinjury from oxidative stressThe effect of SSd on liver fibrosismay be related to its ability to reduce lipid peroxidation [101]

57 Immunomodulatory Effects Yamakage et al determinedthe effects of Radix Bupleuri on spontaneous lymphaticvessel activity The results indicated that Radix Bupleurisignificantly increased the amplitude of spontaneous activityof lymphatic vessels in a concentration-dependent mannerand the mechanisms of this effect seem to be independent ofendothelial function [102] Eugenin (46) and saikochrome A(47) isolated from the MeOH extracts from Bupleurum scor-zonerifolium possessed immunosuppressive effect on humanperipheral blood T cells via inhibiting CD28-costimulatedactivation [62] SSd (10mg intraperitoneally) significantlyactivated peritoneal macrophages in terms of enhancementof phagocytic activity increased level of cellular lysosomalenzyme and suppressed the response of plaque-forming cellsto heterologous erythrocytes by stimulating T and B cells ina dose-dependent manner [103] Moreover SSd modulated

lymphocyte activity through suppressing the T cell responseand increasing the B cell response to different mitogensand the interleukin- (IL-) 2IL-4 production through areceptor-bypassed pathway [41 104 105] In another exper-iment Wong et al found that SSd was shown to inhibitOKT3CD28-costimulated human T cell proliferation andPMA PMAionomycin and Con A-induced mouse T cellactivation in vitro The underlying mechanisms involveddownregulation of NF-kB signaling by suppression of IKKand Akt activities [106]

58 Autophagic Effect Autophagy is a complex processin cells which occurs through the formation of double-membrane vesicles (autophagosomes) which are engulfedby cytoplasmic molecules Then the autophagosome fuseswith the lysosomes leading to degradation of long-livedproteins aggregated proteins and damaged organelles [107ndash109] Moreover autophagy might be triggered by hypoxianutritional deprivation radiation chemical drugs and otherstimulants [110] Autophagy contributes to the pathogenesisof diverse diseases such as neuronal degeneration inflamma-tory bowel disease aging and cancer [111 112] In the previousstudy Law et al demonstrated that the protective pharma-cological effects of Radix Bupleuri might be attributed to itsautophagy inductionThe autophagic effect of Radix Bupleuriplayed an important role in relieving liver disease-relatedsymptoms through anti-inflammatory organ-protective andaggregate removal functions Furthermore the anticancereffects of Radix Bupleuri could be attributed to its autophagyinduction Radix Bupleuri has been found to be an effectivetreatment against depression by regulating metabolite hor-mone and neurotransmitter levels via autophagy-mediatedlipid metabolism [113]

59 Other Pharmacological Effects The effect of the ethanolextract from Radix Bupleuri on cytochrome 450 isoformactivities using a six-drug cocktail approach was evaluatedthe results demonstrated that Radix Bupleuri had stronginduction activity on the CYP2E1 CYP2D6 and CYP3A4which may lead to potential plant drug-drug interactions[114] Radix Bupleuri was shown to be the inhibitor of 120573-glucuronidase The inhibition rate of Radix Bupleuri extractsRB1 (high molecular weight polysaccharides) RB2 (ethanolsolublewater insoluble component) RB3 (extracted by n-butanol soluble in water) and RB4 (low molecular weightwater soluble parts) on the activity of 120573-glucuronidase wasfound to be 4515 3394 2494 and 3454 respectively[115] In pentylenetetrazol (PTZ) induced epilepsy ratsmodelSSa isolated fromRadix Bupleuri significantly reduced seizureseverity and duration while it markedly elevated seizurelatency and downregulated the cytokines expression of p-mTOR p-70S6K L-1120573 and TNF-120572 through inhibitingmTORsignaling pathway [116] He et al demonstrated that SSa obvi-ously reduced lipoprotein uptake to block foamcell formationand the expression of LOX-1 and CD36 boosted cholesterolefflux and the expression of ABCA1 and PPAR120574 throughinhibiting PI3KAktNF-120581BNLRP3 signaling pathway [117]

In another experiment SSc exerted a potent effect on induc-ing human umbilical vein endothelial cells (HUVECs) via-bility and growth Furthermore SSc also induced endothelialcells migration and capillary tube formation The underlyingmechanisms might be related to the gene expression oractivation of matrix metalloproteinase-2 (MMP-2) vascularendothelial growth factor (VEGF) and the p42p44mitogen-activated protein kinase (MAPK ERK) [118] In addition SScwas shown to exhibit inhibitory activities against Alzheimerrsquosdisease (AD) via suppressing the secretion ofA120573 peptides andabnormal tau hyperphosphorylation-mediated microtubuledepolymerization Moreover SSc suppressed A120573 peptide-induced brain endothelial apoptosis indicating that Sscmight be a novel therapeutic tool for treating human AD andother neurodegenerative diseases [119] It was shown by Liuet al for the first time that four polyacetylenes (36ndash39) fromRadix Bupleuri potently exhibited an antidepressant activityby inhibiting the reuptake of serotonin norepinephrine anddopamine The mechanism might be mediated by increasingthe level of monoamines particularly 5-HT andNE [56] Zhuet al suggested that SSa and SSd exhibited the anthelminticactivity against Dactylogyrus spp infecting goldfish Theeffective concentration (EC50) values for SSa and SSd were146 and 074mgminus1 respectively [120]

510 Summary of Pharmacological Effects Radix Bupleuripossesses awide spectrumof pharmacological effects includ-ing anti-inflammatory effect anticancer effect antiviraleffect antipyretic effect antibacterial effect hepatoprotectiveeffect and immunomodulatory effect (Table 3) Based onthese pharmacological effects we can conclude that theextracts and the compounds from this plant can preventor treat certain diseases such as cancer fever malariahepatitis and AD However there is not enough systemicdata of these chemical compounds and their pharmacologicaleffects Thus in the future the pharmacological effects andthe possible molecular mechanisms of the pharmacologicalactivities of Radix Bupleurimust be urgently explored on ourmodern understanding of these diseasesrsquo pathophysiologies

6 Toxicology

Radix Bupleuri has been used for thousands of years asan important traditional herb in China However the toxiceffects of Radix Bupleuri in clinical applications have beengradually reported Several studies have found that the liveris the main organ affected by toxicity particularly in long-term use Major symptoms of liver injury induced by RadixBupleuri included transaminase lifts hepatitis and jaundiceHowever liver functions can return to normal levels aftera specific period [121] Radix Bupleuri has been reportedto exhibit acute hepatitis and acute hepatic necrosis Themean total daily dose was 180 plusmn 335 g which was morethan the Chinese Pharmacopoeia recommended range of 3to 10 g [122] Moreover Radix Bupleuri had been implicatedinmultiple cases of acute hepatitis both as an ingredient aloneand within a particular formulation ldquoXiao-Chai-Hu-Tangrdquo(also known as Syo-Saiko-To in Japanese) [123] Lee et al

demonstrated that two Chinese herbal products containingRadix Bupleuri might increase their risks of liver injuryin HBV-infected patients However further mechanisticresearch on the hepatotoxicity of Radix Bupleuri in thepresence ofHBV infection is warranted [124] In addition theessential oil of Radix Bupleuri induced acute hepatotoxicitywith asynchronous state higher heart rate and fast breathing[125] The total saponins isolated from Radix Bupleuri couldalso cause evidently liver damage in dose-dependent mannermanifested as hepatocyte organic lesion and liver functionchanges as well as hepatocyte death [126]

7 Pharmacokinetics

A selective and sensitive LC-MSMS method was developedand validated for simultaneous determination of SSa b2 cand d in rat plasma afteroral administration of the ethanol-water (50 50 vv) extract of Radix Bupleuri for the firsttime The results demonstrated that SSa c and d wereabsorbed rapidly with 119879max less than 30min [127] In anotherpharmacokinetics experiment of rats Liu et al was the first todevelop an UPLC-PDA-MS method to determine the phar-macokinetics of four polyacetylenes after ig administrationof 95 ethanol extract of Radix Bupleuri The results showedthat compounds 36 and 38 were not detected in rat serumwhereas compounds 37 and 39 exerted a fast distributionphase followed by a relatively slow elimination phase (119905121199114ndash7 h) [56]

8 Future Perspectives and Conclusions

In traditional Chinese medicine Radix Bupleuri has longbeen used regulate the exterior and interiormetabolisms dis-perse evil heat from superficies sooth the liver and promoteyang and qi It has been widely used to treat various diseasesin China Japan Korea and other Asian countries for manycenturies A total of 74 compounds including essential oilstriterpenoid saponins polyacetylenes flavonoids lignansfatty acids and sterols have been isolated and identifiedfrom Radix Bupleuri [39ndash65] Pharmacological studies haverevealed that Radix Bupleuri possesses a variety of biologicaleffects including anti-inflammatory anticancer antiviralantipyretic antibacterial antiobesity immunomodulatoryhepatoprotective neuroprotective and autophagic effects[66ndash120] However there are some aspects that need to befurther investigated

Radix Bupleuri is an ingredient of many patent medicinesor prescriptions Although modern experiments have con-firmed that this drug alone exhibits multiple pharmacolog-ical activities it is important to investigate the molecularmechanisms of Radix Bupleuri combined with other herbsbased on traditional uses Furthermore the pharmacologicaleffects of only a few of the ingredients such as saikosaponinsflavonoids and the essential oils have been investigatedSome polyacetylenes lignans and sterols have not beensufficiently researched in terms of their pharmacologicaleffects Radix Bupleuri shows both hepatoprotection and

hepatotoxicity which appears to be contradictory This phe-nomenon is similar to that of PolygonummultiflorumThunb[128] Based on the literature the main reasons are likelythe administration dosage and delivery time High doses andlong-term drug delivery are more likely to result in livertoxicity whereas low doses and short-term drug deliverymight result in liver protection Therefore this issue needsfurther study

In conclusion this review summarized the traditionaluses botany phytochemistry pharmacology and toxicologyof Radix Bupleuri Moreover it has provided a new founda-tion for further research on its mechanism of action and thedevelopment of better therapeutic agents employing RadixBupleuri in the future It is anticipated that the comprehen-sive and detailed research on toxicity pharmacodynamicspharmacokinetics and molecular mechanism are necessaryto be explored to develop its bioactive compounds as effectivedrugs

51 Anti-inflammatory Effects Radix Bupleuri has beenwidely used for the treatment of several types of chronicinflammatory diseases The crude polysaccharides(80mgkg) isolated from the roots of Bupleurum chinenseDC significantly attenuated lung injury by inhibiting thelevel of myeloperoxidase (MPO) tumor necrosis factor-120572(TNF-120572) and serum nitric oxide (NO) [66] Chun et alreported that saikosaponins from Radix Bupleuri exhibitedanti-inflammatory activity on inflammatory processesincluding inhibition of inflammatory exudation capillarypermeability inflammatory mediators release migrationof white cells connective tissue hyperplasia and a varietyof allergic inflammation [67] Ma et al was the first toshow that saikosaponins exerted anti-inflammatory activityon paw edema mainly via regulating the nicotinate andnicotinamide metabolism and arachidonic acid metabolism[5] Zhu et al found that saikosaponin a (SSa) exhibitedan inhibitory effect on proinflammatory cytokines inLPS-stimulated macrophages The mechanism of theseactions involved the regulation of MAPK and NF-120581B signalspathways [68] In another study SSa dose-dependentlyinhibited the production of ROS TNF-120572 IL-8 COX-2 andiNOS in LPS-stimulated human umbilical endothelial cells(HUVECs) by upregulating of the LXR120572-ABCA1 signalingpathway [69] Moreover Lee et al showed that saikosaponinc (SSc) was also shown to inhibited LPS-induced apoptosis inHUVECs via inhibition of caspase-3 activation and caspase-3-mediated-FAK degradation [70] Zhao et al showed thatSSa also suppressed TNF-120572 and IL-6 concentrations inthe intestines of septic rats through the inhibition of thenucleotide-binding oligomerization domain 2 (NOD2)NF-120581B signaling pathway [71] Saikosaponin d (SSd) has beenreported to inhibit PGE2 production and intracellular freeCa2+ concentration ([Ca2+]i) in a concentration-dependentmanner with an IC50 value of 3 120583m in C6 rat glioma cells[72]

In addition several studies showed that a widerange of Radix Bupleuri preparations also exhibited anti-inflammatory effects in in vitro and in vivo model Li et alshowed that Saireito and its active components (SSd) couldsuppress the proliferation of mesangial cells and expansionof the mesangial matrix in the rat glomerulonephritismodel [73] In experimental chronic pancreatitis rats modelldquoChai-hu-shu-gan powderrdquo exerted anti-inflammatory andantifibrotic effects by inhibiting the expression of nuclearfactor-120581B (NF-120581B) and TNF-120572 mRNA in the pancreas [74]Furthermore it also reduced the abnormally high plasmalevel of cholecystokinin improved the gastricmovement andavoided nausea and flatulence [75] In another experimenta Chinese herbal formula called ldquoRCM-101rdquo (containingFlos magnoliae Radix Bupleuri Radix Glycyrrhizae RadixAngelicae Sinensis etc) inhibited the NO production andiNOS protein expression in LPS-stimulated rat aorta andRaw 2647 macrophages [76]

52 Anticancer Effects The extracts and compounds ofRadix Bupleuri also possessed anticancerantitumor effectThe acetone extract of Bupleurum scorzonerifolium couldinhibit the proliferation of A549 human lung cancer cellsin a dose-dependent manner via causing cell cycle arrestin the G2M phase increasing microtubule stabilizationsuppressing telomerase activity activating ERK 12 andcaspase-39 in A549 cells [77ndash79] Saponins isolated fromRadix Bupleuri also exhibited significantly anti-proliferativeactivity in human non-small cell lung cancer A549 cellsthrough Fas-dependent apoptotic pathway [80] Su et alfound that thewater extracts ofRadix Bupleuri could enhance5-fluorouracil-induced cytotoxicity in HepG2 hepatoma cellsthrough cell arrest at the late G1early S phase while pro-tecting normal blood lymphocytes [6] SSd showed verypotent activity against the HepG2 cell line with an IC50value of 125mgml The mechanism of cytotoxicity was

Several Chinese medicine preparations containing RadixBupleuri also have been traditionally used in the treatmentof tumors and cancer The water extracts of ldquoLong DanXie Gan Wanrdquo exerted a significant growth inhibitory effectin HL60 and HT29 cancer cell lines indicating that thisformulation may possess some chemotherapeutic potential[83] Treatment with ldquoxiao-chai-hu decoctionrdquo exhibited asignificantly lower incidence of hepatocellular carcinoma andreductions in cancer pain and tumor size The underlyingmechanismof the antitumor activities is based on stimulationof the reticuloendothelial system (RES) and is closely relatedof TNF production [84ndash86]

53 Antiviral Effects Wen et al reported that the acetoneextract of Radix Bupleuri possessed a significant antiviruseffect on acute respiratory tract infections with H1N1 virusinfection and suppressed influenzaAvirus-inducedRANTESsecretion in H1N1-infected A549 cells at a concentration of

100 and 200120583gml suggesting that Radix Bupleuri might bebeneficial for the treatment of chronic inflammatory condi-tions followed by viral infection [10] SSc has been reportedto show effective anti-HBV activity through inhibiting DNAexpression of HBsAg HBeAg and HBV [81] Treatmentwith ldquoxiao-chai-hu decoctionrdquo (20120583gml 3 days 20120583gml6 days) could inhibit the production of HBV (119875 lt 00001)and the expression of HBeAg Moreover crude saponinsof Bupleurum chinense DC could inhibit the replication ofHBV (119875 lt 00001) [87] Similarly in another study Yinet al showed that SSd isolated from the MeOH extract ofBupleurum chinense DC exhibited significant bioactivity ininhibitingDNA replication ofHBV [88]The antiviral activityof saikosaponins (a b2 c and d) and their mode of actinwere examined The results showed that all saikosaponinsexerted antiviral activity on human coronavirus-229E atconcentrations of 025ndash25120583m and the strongest activity wasobserved for saikosaponin b2 with an IC50 of 17 120583m Thismechanism might involve interference in the early stage ofviral replication such as absorption and penetration of thevirus [89]

herb exhibited dose-dependent antipyretic capacity on bothfevered rabbits and rats [92]

55 Antibacterial Effects The ethanol extract of Bupleu-rum chinense DC exerted a remarkable bacteriostaticeffect on Gram-negative microorganism Helicobacter pyloriThe bioactive minimum inhibitory concentration (MIC)

value was 60Mm [93] Saikosaponins isolated from RadixBupleuri have been reported to exhibit antibacterial activityparticularly against Pseudomonas aeruginosa and Listeriamonocytogenes The protective effect was attributed to theimmunomodulatory action on macrophages [94] ldquoChaihuinjectionrdquo has also been tested for possible antimicrobialactivity in vitroThe results demonstrated thatmild inhibitionof Staphylococcus aureus was observed but no effects wereobserved against Staphylococcus albusNeisseria gonorrhoeaeDiplococcus pneumoniae haemolytic Streptococcus or Pseu-domonas aeruginosa [95]

56 Hepatoprotective Effects The liver protective effectsagainst CCl4 induced liver injury were investigated aftertreatment ofmicewith raw and vinegar-bakedRadix Bupleuri(5 gkgday) for 14 days The results showed that both rawand processed Radix Bupleuri showed liver protective effectsagainst CCl4 induced liver injury and the vinegar-bakedRadix Bupleuri exerted better effects than that of raw RadixBupleuri [96] Pretreated with saikosaponins especially SSaor SSd showed remarkable inhibition of D-galactosamine-induced hepatic injury through decreasing the activity ofglucose-6-phosphatase and NADPH-cytochrome C reduc-tase and increasing 51015840-nucleotidase activity [97] Similarlybupleurosides III VI IX and XIII and saikosaponin b3isolated from Bupleurum scorzonerifolium Willd were alsofound to exhibit protective effect on the D-galactosamine-induced cytotoxicity in primary cultured rat hepatocytes[98] Further studies also demonstrated that the protectiveeffects of saikosaponins isolated from Bupleurum chinenseDC could prevent hepatocyte injury through regulatingintracellular calcium levels [99] In a rat model with CCl4induced acute hepatic injury the hepatic enzyme levels (GOTGPT and ALP) and the lipid peroxidation in the liver weresignificantly reduced by the administration of SSd [100]Additionally SSd significantly reduced collagen I depositionand alanine aminotransferase level on liver fibrosis rats anddecreased the concentration of transforming growth factor1205731 (TGF-1205731) Moreover SSd was able to alleviate hepatocyteinjury from oxidative stressThe effect of SSd on liver fibrosismay be related to its ability to reduce lipid peroxidation [101]

57 Immunomodulatory Effects Yamakage et al determinedthe effects of Radix Bupleuri on spontaneous lymphaticvessel activity The results indicated that Radix Bupleurisignificantly increased the amplitude of spontaneous activityof lymphatic vessels in a concentration-dependent mannerand the mechanisms of this effect seem to be independent ofendothelial function [102] Eugenin (46) and saikochrome A(47) isolated from the MeOH extracts from Bupleurum scor-zonerifolium possessed immunosuppressive effect on humanperipheral blood T cells via inhibiting CD28-costimulatedactivation [62] SSd (10mg intraperitoneally) significantlyactivated peritoneal macrophages in terms of enhancementof phagocytic activity increased level of cellular lysosomalenzyme and suppressed the response of plaque-forming cellsto heterologous erythrocytes by stimulating T and B cells ina dose-dependent manner [103] Moreover SSd modulated

lymphocyte activity through suppressing the T cell responseand increasing the B cell response to different mitogensand the interleukin- (IL-) 2IL-4 production through areceptor-bypassed pathway [41 104 105] In another exper-iment Wong et al found that SSd was shown to inhibitOKT3CD28-costimulated human T cell proliferation andPMA PMAionomycin and Con A-induced mouse T cellactivation in vitro The underlying mechanisms involveddownregulation of NF-kB signaling by suppression of IKKand Akt activities [106]

58 Autophagic Effect Autophagy is a complex processin cells which occurs through the formation of double-membrane vesicles (autophagosomes) which are engulfedby cytoplasmic molecules Then the autophagosome fuseswith the lysosomes leading to degradation of long-livedproteins aggregated proteins and damaged organelles [107ndash109] Moreover autophagy might be triggered by hypoxianutritional deprivation radiation chemical drugs and otherstimulants [110] Autophagy contributes to the pathogenesisof diverse diseases such as neuronal degeneration inflamma-tory bowel disease aging and cancer [111 112] In the previousstudy Law et al demonstrated that the protective pharma-cological effects of Radix Bupleuri might be attributed to itsautophagy inductionThe autophagic effect of Radix Bupleuriplayed an important role in relieving liver disease-relatedsymptoms through anti-inflammatory organ-protective andaggregate removal functions Furthermore the anticancereffects of Radix Bupleuri could be attributed to its autophagyinduction Radix Bupleuri has been found to be an effectivetreatment against depression by regulating metabolite hor-mone and neurotransmitter levels via autophagy-mediatedlipid metabolism [113]

59 Other Pharmacological Effects The effect of the ethanolextract from Radix Bupleuri on cytochrome 450 isoformactivities using a six-drug cocktail approach was evaluatedthe results demonstrated that Radix Bupleuri had stronginduction activity on the CYP2E1 CYP2D6 and CYP3A4which may lead to potential plant drug-drug interactions[114] Radix Bupleuri was shown to be the inhibitor of 120573-glucuronidase The inhibition rate of Radix Bupleuri extractsRB1 (high molecular weight polysaccharides) RB2 (ethanolsolublewater insoluble component) RB3 (extracted by n-butanol soluble in water) and RB4 (low molecular weightwater soluble parts) on the activity of 120573-glucuronidase wasfound to be 4515 3394 2494 and 3454 respectively[115] In pentylenetetrazol (PTZ) induced epilepsy ratsmodelSSa isolated fromRadix Bupleuri significantly reduced seizureseverity and duration while it markedly elevated seizurelatency and downregulated the cytokines expression of p-mTOR p-70S6K L-1120573 and TNF-120572 through inhibitingmTORsignaling pathway [116] He et al demonstrated that SSa obvi-ously reduced lipoprotein uptake to block foamcell formationand the expression of LOX-1 and CD36 boosted cholesterolefflux and the expression of ABCA1 and PPAR120574 throughinhibiting PI3KAktNF-120581BNLRP3 signaling pathway [117]

In another experiment SSc exerted a potent effect on induc-ing human umbilical vein endothelial cells (HUVECs) via-bility and growth Furthermore SSc also induced endothelialcells migration and capillary tube formation The underlyingmechanisms might be related to the gene expression oractivation of matrix metalloproteinase-2 (MMP-2) vascularendothelial growth factor (VEGF) and the p42p44mitogen-activated protein kinase (MAPK ERK) [118] In addition SScwas shown to exhibit inhibitory activities against Alzheimerrsquosdisease (AD) via suppressing the secretion ofA120573 peptides andabnormal tau hyperphosphorylation-mediated microtubuledepolymerization Moreover SSc suppressed A120573 peptide-induced brain endothelial apoptosis indicating that Sscmight be a novel therapeutic tool for treating human AD andother neurodegenerative diseases [119] It was shown by Liuet al for the first time that four polyacetylenes (36ndash39) fromRadix Bupleuri potently exhibited an antidepressant activityby inhibiting the reuptake of serotonin norepinephrine anddopamine The mechanism might be mediated by increasingthe level of monoamines particularly 5-HT andNE [56] Zhuet al suggested that SSa and SSd exhibited the anthelminticactivity against Dactylogyrus spp infecting goldfish Theeffective concentration (EC50) values for SSa and SSd were146 and 074mgminus1 respectively [120]

510 Summary of Pharmacological Effects Radix Bupleuripossesses awide spectrumof pharmacological effects includ-ing anti-inflammatory effect anticancer effect antiviraleffect antipyretic effect antibacterial effect hepatoprotectiveeffect and immunomodulatory effect (Table 3) Based onthese pharmacological effects we can conclude that theextracts and the compounds from this plant can preventor treat certain diseases such as cancer fever malariahepatitis and AD However there is not enough systemicdata of these chemical compounds and their pharmacologicaleffects Thus in the future the pharmacological effects andthe possible molecular mechanisms of the pharmacologicalactivities of Radix Bupleurimust be urgently explored on ourmodern understanding of these diseasesrsquo pathophysiologies

6 Toxicology

Radix Bupleuri has been used for thousands of years asan important traditional herb in China However the toxiceffects of Radix Bupleuri in clinical applications have beengradually reported Several studies have found that the liveris the main organ affected by toxicity particularly in long-term use Major symptoms of liver injury induced by RadixBupleuri included transaminase lifts hepatitis and jaundiceHowever liver functions can return to normal levels aftera specific period [121] Radix Bupleuri has been reportedto exhibit acute hepatitis and acute hepatic necrosis Themean total daily dose was 180 plusmn 335 g which was morethan the Chinese Pharmacopoeia recommended range of 3to 10 g [122] Moreover Radix Bupleuri had been implicatedinmultiple cases of acute hepatitis both as an ingredient aloneand within a particular formulation ldquoXiao-Chai-Hu-Tangrdquo(also known as Syo-Saiko-To in Japanese) [123] Lee et al

demonstrated that two Chinese herbal products containingRadix Bupleuri might increase their risks of liver injuryin HBV-infected patients However further mechanisticresearch on the hepatotoxicity of Radix Bupleuri in thepresence ofHBV infection is warranted [124] In addition theessential oil of Radix Bupleuri induced acute hepatotoxicitywith asynchronous state higher heart rate and fast breathing[125] The total saponins isolated from Radix Bupleuri couldalso cause evidently liver damage in dose-dependent mannermanifested as hepatocyte organic lesion and liver functionchanges as well as hepatocyte death [126]

7 Pharmacokinetics

A selective and sensitive LC-MSMS method was developedand validated for simultaneous determination of SSa b2 cand d in rat plasma afteroral administration of the ethanol-water (50 50 vv) extract of Radix Bupleuri for the firsttime The results demonstrated that SSa c and d wereabsorbed rapidly with 119879max less than 30min [127] In anotherpharmacokinetics experiment of rats Liu et al was the first todevelop an UPLC-PDA-MS method to determine the phar-macokinetics of four polyacetylenes after ig administrationof 95 ethanol extract of Radix Bupleuri The results showedthat compounds 36 and 38 were not detected in rat serumwhereas compounds 37 and 39 exerted a fast distributionphase followed by a relatively slow elimination phase (119905121199114ndash7 h) [56]

8 Future Perspectives and Conclusions

In traditional Chinese medicine Radix Bupleuri has longbeen used regulate the exterior and interiormetabolisms dis-perse evil heat from superficies sooth the liver and promoteyang and qi It has been widely used to treat various diseasesin China Japan Korea and other Asian countries for manycenturies A total of 74 compounds including essential oilstriterpenoid saponins polyacetylenes flavonoids lignansfatty acids and sterols have been isolated and identifiedfrom Radix Bupleuri [39ndash65] Pharmacological studies haverevealed that Radix Bupleuri possesses a variety of biologicaleffects including anti-inflammatory anticancer antiviralantipyretic antibacterial antiobesity immunomodulatoryhepatoprotective neuroprotective and autophagic effects[66ndash120] However there are some aspects that need to befurther investigated

Radix Bupleuri is an ingredient of many patent medicinesor prescriptions Although modern experiments have con-firmed that this drug alone exhibits multiple pharmacolog-ical activities it is important to investigate the molecularmechanisms of Radix Bupleuri combined with other herbsbased on traditional uses Furthermore the pharmacologicaleffects of only a few of the ingredients such as saikosaponinsflavonoids and the essential oils have been investigatedSome polyacetylenes lignans and sterols have not beensufficiently researched in terms of their pharmacologicaleffects Radix Bupleuri shows both hepatoprotection and

hepatotoxicity which appears to be contradictory This phe-nomenon is similar to that of PolygonummultiflorumThunb[128] Based on the literature the main reasons are likelythe administration dosage and delivery time High doses andlong-term drug delivery are more likely to result in livertoxicity whereas low doses and short-term drug deliverymight result in liver protection Therefore this issue needsfurther study

In conclusion this review summarized the traditionaluses botany phytochemistry pharmacology and toxicologyof Radix Bupleuri Moreover it has provided a new founda-tion for further research on its mechanism of action and thedevelopment of better therapeutic agents employing RadixBupleuri in the future It is anticipated that the comprehen-sive and detailed research on toxicity pharmacodynamicspharmacokinetics and molecular mechanism are necessaryto be explored to develop its bioactive compounds as effectivedrugs

Several Chinese medicine preparations containing RadixBupleuri also have been traditionally used in the treatmentof tumors and cancer The water extracts of ldquoLong DanXie Gan Wanrdquo exerted a significant growth inhibitory effectin HL60 and HT29 cancer cell lines indicating that thisformulation may possess some chemotherapeutic potential[83] Treatment with ldquoxiao-chai-hu decoctionrdquo exhibited asignificantly lower incidence of hepatocellular carcinoma andreductions in cancer pain and tumor size The underlyingmechanismof the antitumor activities is based on stimulationof the reticuloendothelial system (RES) and is closely relatedof TNF production [84ndash86]

53 Antiviral Effects Wen et al reported that the acetoneextract of Radix Bupleuri possessed a significant antiviruseffect on acute respiratory tract infections with H1N1 virusinfection and suppressed influenzaAvirus-inducedRANTESsecretion in H1N1-infected A549 cells at a concentration of

100 and 200120583gml suggesting that Radix Bupleuri might bebeneficial for the treatment of chronic inflammatory condi-tions followed by viral infection [10] SSc has been reportedto show effective anti-HBV activity through inhibiting DNAexpression of HBsAg HBeAg and HBV [81] Treatmentwith ldquoxiao-chai-hu decoctionrdquo (20120583gml 3 days 20120583gml6 days) could inhibit the production of HBV (119875 lt 00001)and the expression of HBeAg Moreover crude saponinsof Bupleurum chinense DC could inhibit the replication ofHBV (119875 lt 00001) [87] Similarly in another study Yinet al showed that SSd isolated from the MeOH extract ofBupleurum chinense DC exhibited significant bioactivity ininhibitingDNA replication ofHBV [88]The antiviral activityof saikosaponins (a b2 c and d) and their mode of actinwere examined The results showed that all saikosaponinsexerted antiviral activity on human coronavirus-229E atconcentrations of 025ndash25120583m and the strongest activity wasobserved for saikosaponin b2 with an IC50 of 17 120583m Thismechanism might involve interference in the early stage ofviral replication such as absorption and penetration of thevirus [89]

54 Antipyretic Effects The water extract of Radix Bupleuriwas reported to exert its antipyretic effect on dry yeast-induced high fever rats The mechanism is related to the

adjustment of synthesis and exudation of cyclic adenosinemonophosphate (cAMP) and arginine vasopressin (AVP)[90] A novel in situ gel system for nasal delivery of theessential oil from Radix Bupleuri was prepared The resultssuggested that Radix Bupleuri in situ gel can be moreeffective than the solution in the treatment of fever [91] Asimilar study showed that the essential oil extracted from the

herb exhibited dose-dependent antipyretic capacity on bothfevered rabbits and rats [92]

55 Antibacterial Effects The ethanol extract of Bupleu-rum chinense DC exerted a remarkable bacteriostaticeffect on Gram-negative microorganism Helicobacter pyloriThe bioactive minimum inhibitory concentration (MIC)

value was 60Mm [93] Saikosaponins isolated from RadixBupleuri have been reported to exhibit antibacterial activityparticularly against Pseudomonas aeruginosa and Listeriamonocytogenes The protective effect was attributed to theimmunomodulatory action on macrophages [94] ldquoChaihuinjectionrdquo has also been tested for possible antimicrobialactivity in vitroThe results demonstrated thatmild inhibitionof Staphylococcus aureus was observed but no effects wereobserved against Staphylococcus albusNeisseria gonorrhoeaeDiplococcus pneumoniae haemolytic Streptococcus or Pseu-domonas aeruginosa [95]

56 Hepatoprotective Effects The liver protective effectsagainst CCl4 induced liver injury were investigated aftertreatment ofmicewith raw and vinegar-bakedRadix Bupleuri(5 gkgday) for 14 days The results showed that both rawand processed Radix Bupleuri showed liver protective effectsagainst CCl4 induced liver injury and the vinegar-bakedRadix Bupleuri exerted better effects than that of raw RadixBupleuri [96] Pretreated with saikosaponins especially SSaor SSd showed remarkable inhibition of D-galactosamine-induced hepatic injury through decreasing the activity ofglucose-6-phosphatase and NADPH-cytochrome C reduc-tase and increasing 51015840-nucleotidase activity [97] Similarlybupleurosides III VI IX and XIII and saikosaponin b3isolated from Bupleurum scorzonerifolium Willd were alsofound to exhibit protective effect on the D-galactosamine-induced cytotoxicity in primary cultured rat hepatocytes[98] Further studies also demonstrated that the protectiveeffects of saikosaponins isolated from Bupleurum chinenseDC could prevent hepatocyte injury through regulatingintracellular calcium levels [99] In a rat model with CCl4induced acute hepatic injury the hepatic enzyme levels (GOTGPT and ALP) and the lipid peroxidation in the liver weresignificantly reduced by the administration of SSd [100]Additionally SSd significantly reduced collagen I depositionand alanine aminotransferase level on liver fibrosis rats anddecreased the concentration of transforming growth factor1205731 (TGF-1205731) Moreover SSd was able to alleviate hepatocyteinjury from oxidative stressThe effect of SSd on liver fibrosismay be related to its ability to reduce lipid peroxidation [101]

57 Immunomodulatory Effects Yamakage et al determinedthe effects of Radix Bupleuri on spontaneous lymphaticvessel activity The results indicated that Radix Bupleurisignificantly increased the amplitude of spontaneous activityof lymphatic vessels in a concentration-dependent mannerand the mechanisms of this effect seem to be independent ofendothelial function [102] Eugenin (46) and saikochrome A(47) isolated from the MeOH extracts from Bupleurum scor-zonerifolium possessed immunosuppressive effect on humanperipheral blood T cells via inhibiting CD28-costimulatedactivation [62] SSd (10mg intraperitoneally) significantlyactivated peritoneal macrophages in terms of enhancementof phagocytic activity increased level of cellular lysosomalenzyme and suppressed the response of plaque-forming cellsto heterologous erythrocytes by stimulating T and B cells ina dose-dependent manner [103] Moreover SSd modulated

lymphocyte activity through suppressing the T cell responseand increasing the B cell response to different mitogensand the interleukin- (IL-) 2IL-4 production through areceptor-bypassed pathway [41 104 105] In another exper-iment Wong et al found that SSd was shown to inhibitOKT3CD28-costimulated human T cell proliferation andPMA PMAionomycin and Con A-induced mouse T cellactivation in vitro The underlying mechanisms involveddownregulation of NF-kB signaling by suppression of IKKand Akt activities [106]

58 Autophagic Effect Autophagy is a complex processin cells which occurs through the formation of double-membrane vesicles (autophagosomes) which are engulfedby cytoplasmic molecules Then the autophagosome fuseswith the lysosomes leading to degradation of long-livedproteins aggregated proteins and damaged organelles [107ndash109] Moreover autophagy might be triggered by hypoxianutritional deprivation radiation chemical drugs and otherstimulants [110] Autophagy contributes to the pathogenesisof diverse diseases such as neuronal degeneration inflamma-tory bowel disease aging and cancer [111 112] In the previousstudy Law et al demonstrated that the protective pharma-cological effects of Radix Bupleuri might be attributed to itsautophagy inductionThe autophagic effect of Radix Bupleuriplayed an important role in relieving liver disease-relatedsymptoms through anti-inflammatory organ-protective andaggregate removal functions Furthermore the anticancereffects of Radix Bupleuri could be attributed to its autophagyinduction Radix Bupleuri has been found to be an effectivetreatment against depression by regulating metabolite hor-mone and neurotransmitter levels via autophagy-mediatedlipid metabolism [113]

59 Other Pharmacological Effects The effect of the ethanolextract from Radix Bupleuri on cytochrome 450 isoformactivities using a six-drug cocktail approach was evaluatedthe results demonstrated that Radix Bupleuri had stronginduction activity on the CYP2E1 CYP2D6 and CYP3A4which may lead to potential plant drug-drug interactions[114] Radix Bupleuri was shown to be the inhibitor of 120573-glucuronidase The inhibition rate of Radix Bupleuri extractsRB1 (high molecular weight polysaccharides) RB2 (ethanolsolublewater insoluble component) RB3 (extracted by n-butanol soluble in water) and RB4 (low molecular weightwater soluble parts) on the activity of 120573-glucuronidase wasfound to be 4515 3394 2494 and 3454 respectively[115] In pentylenetetrazol (PTZ) induced epilepsy ratsmodelSSa isolated fromRadix Bupleuri significantly reduced seizureseverity and duration while it markedly elevated seizurelatency and downregulated the cytokines expression of p-mTOR p-70S6K L-1120573 and TNF-120572 through inhibitingmTORsignaling pathway [116] He et al demonstrated that SSa obvi-ously reduced lipoprotein uptake to block foamcell formationand the expression of LOX-1 and CD36 boosted cholesterolefflux and the expression of ABCA1 and PPAR120574 throughinhibiting PI3KAktNF-120581BNLRP3 signaling pathway [117]

In another experiment SSc exerted a potent effect on induc-ing human umbilical vein endothelial cells (HUVECs) via-bility and growth Furthermore SSc also induced endothelialcells migration and capillary tube formation The underlyingmechanisms might be related to the gene expression oractivation of matrix metalloproteinase-2 (MMP-2) vascularendothelial growth factor (VEGF) and the p42p44mitogen-activated protein kinase (MAPK ERK) [118] In addition SScwas shown to exhibit inhibitory activities against Alzheimerrsquosdisease (AD) via suppressing the secretion ofA120573 peptides andabnormal tau hyperphosphorylation-mediated microtubuledepolymerization Moreover SSc suppressed A120573 peptide-induced brain endothelial apoptosis indicating that Sscmight be a novel therapeutic tool for treating human AD andother neurodegenerative diseases [119] It was shown by Liuet al for the first time that four polyacetylenes (36ndash39) fromRadix Bupleuri potently exhibited an antidepressant activityby inhibiting the reuptake of serotonin norepinephrine anddopamine The mechanism might be mediated by increasingthe level of monoamines particularly 5-HT andNE [56] Zhuet al suggested that SSa and SSd exhibited the anthelminticactivity against Dactylogyrus spp infecting goldfish Theeffective concentration (EC50) values for SSa and SSd were146 and 074mgminus1 respectively [120]

510 Summary of Pharmacological Effects Radix Bupleuripossesses awide spectrumof pharmacological effects includ-ing anti-inflammatory effect anticancer effect antiviraleffect antipyretic effect antibacterial effect hepatoprotectiveeffect and immunomodulatory effect (Table 3) Based onthese pharmacological effects we can conclude that theextracts and the compounds from this plant can preventor treat certain diseases such as cancer fever malariahepatitis and AD However there is not enough systemicdata of these chemical compounds and their pharmacologicaleffects Thus in the future the pharmacological effects andthe possible molecular mechanisms of the pharmacologicalactivities of Radix Bupleurimust be urgently explored on ourmodern understanding of these diseasesrsquo pathophysiologies

6 Toxicology

Radix Bupleuri has been used for thousands of years asan important traditional herb in China However the toxiceffects of Radix Bupleuri in clinical applications have beengradually reported Several studies have found that the liveris the main organ affected by toxicity particularly in long-term use Major symptoms of liver injury induced by RadixBupleuri included transaminase lifts hepatitis and jaundiceHowever liver functions can return to normal levels aftera specific period [121] Radix Bupleuri has been reportedto exhibit acute hepatitis and acute hepatic necrosis Themean total daily dose was 180 plusmn 335 g which was morethan the Chinese Pharmacopoeia recommended range of 3to 10 g [122] Moreover Radix Bupleuri had been implicatedinmultiple cases of acute hepatitis both as an ingredient aloneand within a particular formulation ldquoXiao-Chai-Hu-Tangrdquo(also known as Syo-Saiko-To in Japanese) [123] Lee et al

demonstrated that two Chinese herbal products containingRadix Bupleuri might increase their risks of liver injuryin HBV-infected patients However further mechanisticresearch on the hepatotoxicity of Radix Bupleuri in thepresence ofHBV infection is warranted [124] In addition theessential oil of Radix Bupleuri induced acute hepatotoxicitywith asynchronous state higher heart rate and fast breathing[125] The total saponins isolated from Radix Bupleuri couldalso cause evidently liver damage in dose-dependent mannermanifested as hepatocyte organic lesion and liver functionchanges as well as hepatocyte death [126]

7 Pharmacokinetics

A selective and sensitive LC-MSMS method was developedand validated for simultaneous determination of SSa b2 cand d in rat plasma afteroral administration of the ethanol-water (50 50 vv) extract of Radix Bupleuri for the firsttime The results demonstrated that SSa c and d wereabsorbed rapidly with 119879max less than 30min [127] In anotherpharmacokinetics experiment of rats Liu et al was the first todevelop an UPLC-PDA-MS method to determine the phar-macokinetics of four polyacetylenes after ig administrationof 95 ethanol extract of Radix Bupleuri The results showedthat compounds 36 and 38 were not detected in rat serumwhereas compounds 37 and 39 exerted a fast distributionphase followed by a relatively slow elimination phase (119905121199114ndash7 h) [56]

8 Future Perspectives and Conclusions

In traditional Chinese medicine Radix Bupleuri has longbeen used regulate the exterior and interiormetabolisms dis-perse evil heat from superficies sooth the liver and promoteyang and qi It has been widely used to treat various diseasesin China Japan Korea and other Asian countries for manycenturies A total of 74 compounds including essential oilstriterpenoid saponins polyacetylenes flavonoids lignansfatty acids and sterols have been isolated and identifiedfrom Radix Bupleuri [39ndash65] Pharmacological studies haverevealed that Radix Bupleuri possesses a variety of biologicaleffects including anti-inflammatory anticancer antiviralantipyretic antibacterial antiobesity immunomodulatoryhepatoprotective neuroprotective and autophagic effects[66ndash120] However there are some aspects that need to befurther investigated

Radix Bupleuri is an ingredient of many patent medicinesor prescriptions Although modern experiments have con-firmed that this drug alone exhibits multiple pharmacolog-ical activities it is important to investigate the molecularmechanisms of Radix Bupleuri combined with other herbsbased on traditional uses Furthermore the pharmacologicaleffects of only a few of the ingredients such as saikosaponinsflavonoids and the essential oils have been investigatedSome polyacetylenes lignans and sterols have not beensufficiently researched in terms of their pharmacologicaleffects Radix Bupleuri shows both hepatoprotection and

hepatotoxicity which appears to be contradictory This phe-nomenon is similar to that of PolygonummultiflorumThunb[128] Based on the literature the main reasons are likelythe administration dosage and delivery time High doses andlong-term drug delivery are more likely to result in livertoxicity whereas low doses and short-term drug deliverymight result in liver protection Therefore this issue needsfurther study

In conclusion this review summarized the traditionaluses botany phytochemistry pharmacology and toxicologyof Radix Bupleuri Moreover it has provided a new founda-tion for further research on its mechanism of action and thedevelopment of better therapeutic agents employing RadixBupleuri in the future It is anticipated that the comprehen-sive and detailed research on toxicity pharmacodynamicspharmacokinetics and molecular mechanism are necessaryto be explored to develop its bioactive compounds as effectivedrugs

Several Chinese medicine preparations containing RadixBupleuri also have been traditionally used in the treatmentof tumors and cancer The water extracts of ldquoLong DanXie Gan Wanrdquo exerted a significant growth inhibitory effectin HL60 and HT29 cancer cell lines indicating that thisformulation may possess some chemotherapeutic potential[83] Treatment with ldquoxiao-chai-hu decoctionrdquo exhibited asignificantly lower incidence of hepatocellular carcinoma andreductions in cancer pain and tumor size The underlyingmechanismof the antitumor activities is based on stimulationof the reticuloendothelial system (RES) and is closely relatedof TNF production [84ndash86]

53 Antiviral Effects Wen et al reported that the acetoneextract of Radix Bupleuri possessed a significant antiviruseffect on acute respiratory tract infections with H1N1 virusinfection and suppressed influenzaAvirus-inducedRANTESsecretion in H1N1-infected A549 cells at a concentration of

100 and 200120583gml suggesting that Radix Bupleuri might bebeneficial for the treatment of chronic inflammatory condi-tions followed by viral infection [10] SSc has been reportedto show effective anti-HBV activity through inhibiting DNAexpression of HBsAg HBeAg and HBV [81] Treatmentwith ldquoxiao-chai-hu decoctionrdquo (20120583gml 3 days 20120583gml6 days) could inhibit the production of HBV (119875 lt 00001)and the expression of HBeAg Moreover crude saponinsof Bupleurum chinense DC could inhibit the replication ofHBV (119875 lt 00001) [87] Similarly in another study Yinet al showed that SSd isolated from the MeOH extract ofBupleurum chinense DC exhibited significant bioactivity ininhibitingDNA replication ofHBV [88]The antiviral activityof saikosaponins (a b2 c and d) and their mode of actinwere examined The results showed that all saikosaponinsexerted antiviral activity on human coronavirus-229E atconcentrations of 025ndash25120583m and the strongest activity wasobserved for saikosaponin b2 with an IC50 of 17 120583m Thismechanism might involve interference in the early stage ofviral replication such as absorption and penetration of thevirus [89]

54 Antipyretic Effects The water extract of Radix Bupleuriwas reported to exert its antipyretic effect on dry yeast-induced high fever rats The mechanism is related to the

adjustment of synthesis and exudation of cyclic adenosinemonophosphate (cAMP) and arginine vasopressin (AVP)[90] A novel in situ gel system for nasal delivery of theessential oil from Radix Bupleuri was prepared The resultssuggested that Radix Bupleuri in situ gel can be moreeffective than the solution in the treatment of fever [91] Asimilar study showed that the essential oil extracted from the

herb exhibited dose-dependent antipyretic capacity on bothfevered rabbits and rats [92]

55 Antibacterial Effects The ethanol extract of Bupleu-rum chinense DC exerted a remarkable bacteriostaticeffect on Gram-negative microorganism Helicobacter pyloriThe bioactive minimum inhibitory concentration (MIC)

value was 60Mm [93] Saikosaponins isolated from RadixBupleuri have been reported to exhibit antibacterial activityparticularly against Pseudomonas aeruginosa and Listeriamonocytogenes The protective effect was attributed to theimmunomodulatory action on macrophages [94] ldquoChaihuinjectionrdquo has also been tested for possible antimicrobialactivity in vitroThe results demonstrated thatmild inhibitionof Staphylococcus aureus was observed but no effects wereobserved against Staphylococcus albusNeisseria gonorrhoeaeDiplococcus pneumoniae haemolytic Streptococcus or Pseu-domonas aeruginosa [95]

56 Hepatoprotective Effects The liver protective effectsagainst CCl4 induced liver injury were investigated aftertreatment ofmicewith raw and vinegar-bakedRadix Bupleuri(5 gkgday) for 14 days The results showed that both rawand processed Radix Bupleuri showed liver protective effectsagainst CCl4 induced liver injury and the vinegar-bakedRadix Bupleuri exerted better effects than that of raw RadixBupleuri [96] Pretreated with saikosaponins especially SSaor SSd showed remarkable inhibition of D-galactosamine-induced hepatic injury through decreasing the activity ofglucose-6-phosphatase and NADPH-cytochrome C reduc-tase and increasing 51015840-nucleotidase activity [97] Similarlybupleurosides III VI IX and XIII and saikosaponin b3isolated from Bupleurum scorzonerifolium Willd were alsofound to exhibit protective effect on the D-galactosamine-induced cytotoxicity in primary cultured rat hepatocytes[98] Further studies also demonstrated that the protectiveeffects of saikosaponins isolated from Bupleurum chinenseDC could prevent hepatocyte injury through regulatingintracellular calcium levels [99] In a rat model with CCl4induced acute hepatic injury the hepatic enzyme levels (GOTGPT and ALP) and the lipid peroxidation in the liver weresignificantly reduced by the administration of SSd [100]Additionally SSd significantly reduced collagen I depositionand alanine aminotransferase level on liver fibrosis rats anddecreased the concentration of transforming growth factor1205731 (TGF-1205731) Moreover SSd was able to alleviate hepatocyteinjury from oxidative stressThe effect of SSd on liver fibrosismay be related to its ability to reduce lipid peroxidation [101]

57 Immunomodulatory Effects Yamakage et al determinedthe effects of Radix Bupleuri on spontaneous lymphaticvessel activity The results indicated that Radix Bupleurisignificantly increased the amplitude of spontaneous activityof lymphatic vessels in a concentration-dependent mannerand the mechanisms of this effect seem to be independent ofendothelial function [102] Eugenin (46) and saikochrome A(47) isolated from the MeOH extracts from Bupleurum scor-zonerifolium possessed immunosuppressive effect on humanperipheral blood T cells via inhibiting CD28-costimulatedactivation [62] SSd (10mg intraperitoneally) significantlyactivated peritoneal macrophages in terms of enhancementof phagocytic activity increased level of cellular lysosomalenzyme and suppressed the response of plaque-forming cellsto heterologous erythrocytes by stimulating T and B cells ina dose-dependent manner [103] Moreover SSd modulated

lymphocyte activity through suppressing the T cell responseand increasing the B cell response to different mitogensand the interleukin- (IL-) 2IL-4 production through areceptor-bypassed pathway [41 104 105] In another exper-iment Wong et al found that SSd was shown to inhibitOKT3CD28-costimulated human T cell proliferation andPMA PMAionomycin and Con A-induced mouse T cellactivation in vitro The underlying mechanisms involveddownregulation of NF-kB signaling by suppression of IKKand Akt activities [106]

58 Autophagic Effect Autophagy is a complex processin cells which occurs through the formation of double-membrane vesicles (autophagosomes) which are engulfedby cytoplasmic molecules Then the autophagosome fuseswith the lysosomes leading to degradation of long-livedproteins aggregated proteins and damaged organelles [107ndash109] Moreover autophagy might be triggered by hypoxianutritional deprivation radiation chemical drugs and otherstimulants [110] Autophagy contributes to the pathogenesisof diverse diseases such as neuronal degeneration inflamma-tory bowel disease aging and cancer [111 112] In the previousstudy Law et al demonstrated that the protective pharma-cological effects of Radix Bupleuri might be attributed to itsautophagy inductionThe autophagic effect of Radix Bupleuriplayed an important role in relieving liver disease-relatedsymptoms through anti-inflammatory organ-protective andaggregate removal functions Furthermore the anticancereffects of Radix Bupleuri could be attributed to its autophagyinduction Radix Bupleuri has been found to be an effectivetreatment against depression by regulating metabolite hor-mone and neurotransmitter levels via autophagy-mediatedlipid metabolism [113]

59 Other Pharmacological Effects The effect of the ethanolextract from Radix Bupleuri on cytochrome 450 isoformactivities using a six-drug cocktail approach was evaluatedthe results demonstrated that Radix Bupleuri had stronginduction activity on the CYP2E1 CYP2D6 and CYP3A4which may lead to potential plant drug-drug interactions[114] Radix Bupleuri was shown to be the inhibitor of 120573-glucuronidase The inhibition rate of Radix Bupleuri extractsRB1 (high molecular weight polysaccharides) RB2 (ethanolsolublewater insoluble component) RB3 (extracted by n-butanol soluble in water) and RB4 (low molecular weightwater soluble parts) on the activity of 120573-glucuronidase wasfound to be 4515 3394 2494 and 3454 respectively[115] In pentylenetetrazol (PTZ) induced epilepsy ratsmodelSSa isolated fromRadix Bupleuri significantly reduced seizureseverity and duration while it markedly elevated seizurelatency and downregulated the cytokines expression of p-mTOR p-70S6K L-1120573 and TNF-120572 through inhibitingmTORsignaling pathway [116] He et al demonstrated that SSa obvi-ously reduced lipoprotein uptake to block foamcell formationand the expression of LOX-1 and CD36 boosted cholesterolefflux and the expression of ABCA1 and PPAR120574 throughinhibiting PI3KAktNF-120581BNLRP3 signaling pathway [117]

In another experiment SSc exerted a potent effect on induc-ing human umbilical vein endothelial cells (HUVECs) via-bility and growth Furthermore SSc also induced endothelialcells migration and capillary tube formation The underlyingmechanisms might be related to the gene expression oractivation of matrix metalloproteinase-2 (MMP-2) vascularendothelial growth factor (VEGF) and the p42p44mitogen-activated protein kinase (MAPK ERK) [118] In addition SScwas shown to exhibit inhibitory activities against Alzheimerrsquosdisease (AD) via suppressing the secretion ofA120573 peptides andabnormal tau hyperphosphorylation-mediated microtubuledepolymerization Moreover SSc suppressed A120573 peptide-induced brain endothelial apoptosis indicating that Sscmight be a novel therapeutic tool for treating human AD andother neurodegenerative diseases [119] It was shown by Liuet al for the first time that four polyacetylenes (36ndash39) fromRadix Bupleuri potently exhibited an antidepressant activityby inhibiting the reuptake of serotonin norepinephrine anddopamine The mechanism might be mediated by increasingthe level of monoamines particularly 5-HT andNE [56] Zhuet al suggested that SSa and SSd exhibited the anthelminticactivity against Dactylogyrus spp infecting goldfish Theeffective concentration (EC50) values for SSa and SSd were146 and 074mgminus1 respectively [120]

510 Summary of Pharmacological Effects Radix Bupleuripossesses awide spectrumof pharmacological effects includ-ing anti-inflammatory effect anticancer effect antiviraleffect antipyretic effect antibacterial effect hepatoprotectiveeffect and immunomodulatory effect (Table 3) Based onthese pharmacological effects we can conclude that theextracts and the compounds from this plant can preventor treat certain diseases such as cancer fever malariahepatitis and AD However there is not enough systemicdata of these chemical compounds and their pharmacologicaleffects Thus in the future the pharmacological effects andthe possible molecular mechanisms of the pharmacologicalactivities of Radix Bupleurimust be urgently explored on ourmodern understanding of these diseasesrsquo pathophysiologies

6 Toxicology

Radix Bupleuri has been used for thousands of years asan important traditional herb in China However the toxiceffects of Radix Bupleuri in clinical applications have beengradually reported Several studies have found that the liveris the main organ affected by toxicity particularly in long-term use Major symptoms of liver injury induced by RadixBupleuri included transaminase lifts hepatitis and jaundiceHowever liver functions can return to normal levels aftera specific period [121] Radix Bupleuri has been reportedto exhibit acute hepatitis and acute hepatic necrosis Themean total daily dose was 180 plusmn 335 g which was morethan the Chinese Pharmacopoeia recommended range of 3to 10 g [122] Moreover Radix Bupleuri had been implicatedinmultiple cases of acute hepatitis both as an ingredient aloneand within a particular formulation ldquoXiao-Chai-Hu-Tangrdquo(also known as Syo-Saiko-To in Japanese) [123] Lee et al

demonstrated that two Chinese herbal products containingRadix Bupleuri might increase their risks of liver injuryin HBV-infected patients However further mechanisticresearch on the hepatotoxicity of Radix Bupleuri in thepresence ofHBV infection is warranted [124] In addition theessential oil of Radix Bupleuri induced acute hepatotoxicitywith asynchronous state higher heart rate and fast breathing[125] The total saponins isolated from Radix Bupleuri couldalso cause evidently liver damage in dose-dependent mannermanifested as hepatocyte organic lesion and liver functionchanges as well as hepatocyte death [126]

7 Pharmacokinetics

A selective and sensitive LC-MSMS method was developedand validated for simultaneous determination of SSa b2 cand d in rat plasma afteroral administration of the ethanol-water (50 50 vv) extract of Radix Bupleuri for the firsttime The results demonstrated that SSa c and d wereabsorbed rapidly with 119879max less than 30min [127] In anotherpharmacokinetics experiment of rats Liu et al was the first todevelop an UPLC-PDA-MS method to determine the phar-macokinetics of four polyacetylenes after ig administrationof 95 ethanol extract of Radix Bupleuri The results showedthat compounds 36 and 38 were not detected in rat serumwhereas compounds 37 and 39 exerted a fast distributionphase followed by a relatively slow elimination phase (119905121199114ndash7 h) [56]

8 Future Perspectives and Conclusions

In traditional Chinese medicine Radix Bupleuri has longbeen used regulate the exterior and interiormetabolisms dis-perse evil heat from superficies sooth the liver and promoteyang and qi It has been widely used to treat various diseasesin China Japan Korea and other Asian countries for manycenturies A total of 74 compounds including essential oilstriterpenoid saponins polyacetylenes flavonoids lignansfatty acids and sterols have been isolated and identifiedfrom Radix Bupleuri [39ndash65] Pharmacological studies haverevealed that Radix Bupleuri possesses a variety of biologicaleffects including anti-inflammatory anticancer antiviralantipyretic antibacterial antiobesity immunomodulatoryhepatoprotective neuroprotective and autophagic effects[66ndash120] However there are some aspects that need to befurther investigated

Radix Bupleuri is an ingredient of many patent medicinesor prescriptions Although modern experiments have con-firmed that this drug alone exhibits multiple pharmacolog-ical activities it is important to investigate the molecularmechanisms of Radix Bupleuri combined with other herbsbased on traditional uses Furthermore the pharmacologicaleffects of only a few of the ingredients such as saikosaponinsflavonoids and the essential oils have been investigatedSome polyacetylenes lignans and sterols have not beensufficiently researched in terms of their pharmacologicaleffects Radix Bupleuri shows both hepatoprotection and

hepatotoxicity which appears to be contradictory This phe-nomenon is similar to that of PolygonummultiflorumThunb[128] Based on the literature the main reasons are likelythe administration dosage and delivery time High doses andlong-term drug delivery are more likely to result in livertoxicity whereas low doses and short-term drug deliverymight result in liver protection Therefore this issue needsfurther study

In conclusion this review summarized the traditionaluses botany phytochemistry pharmacology and toxicologyof Radix Bupleuri Moreover it has provided a new founda-tion for further research on its mechanism of action and thedevelopment of better therapeutic agents employing RadixBupleuri in the future It is anticipated that the comprehen-sive and detailed research on toxicity pharmacodynamicspharmacokinetics and molecular mechanism are necessaryto be explored to develop its bioactive compounds as effectivedrugs

adjustment of synthesis and exudation of cyclic adenosinemonophosphate (cAMP) and arginine vasopressin (AVP)[90] A novel in situ gel system for nasal delivery of theessential oil from Radix Bupleuri was prepared The resultssuggested that Radix Bupleuri in situ gel can be moreeffective than the solution in the treatment of fever [91] Asimilar study showed that the essential oil extracted from the

herb exhibited dose-dependent antipyretic capacity on bothfevered rabbits and rats [92]

55 Antibacterial Effects The ethanol extract of Bupleu-rum chinense DC exerted a remarkable bacteriostaticeffect on Gram-negative microorganism Helicobacter pyloriThe bioactive minimum inhibitory concentration (MIC)

value was 60Mm [93] Saikosaponins isolated from RadixBupleuri have been reported to exhibit antibacterial activityparticularly against Pseudomonas aeruginosa and Listeriamonocytogenes The protective effect was attributed to theimmunomodulatory action on macrophages [94] ldquoChaihuinjectionrdquo has also been tested for possible antimicrobialactivity in vitroThe results demonstrated thatmild inhibitionof Staphylococcus aureus was observed but no effects wereobserved against Staphylococcus albusNeisseria gonorrhoeaeDiplococcus pneumoniae haemolytic Streptococcus or Pseu-domonas aeruginosa [95]

56 Hepatoprotective Effects The liver protective effectsagainst CCl4 induced liver injury were investigated aftertreatment ofmicewith raw and vinegar-bakedRadix Bupleuri(5 gkgday) for 14 days The results showed that both rawand processed Radix Bupleuri showed liver protective effectsagainst CCl4 induced liver injury and the vinegar-bakedRadix Bupleuri exerted better effects than that of raw RadixBupleuri [96] Pretreated with saikosaponins especially SSaor SSd showed remarkable inhibition of D-galactosamine-induced hepatic injury through decreasing the activity ofglucose-6-phosphatase and NADPH-cytochrome C reduc-tase and increasing 51015840-nucleotidase activity [97] Similarlybupleurosides III VI IX and XIII and saikosaponin b3isolated from Bupleurum scorzonerifolium Willd were alsofound to exhibit protective effect on the D-galactosamine-induced cytotoxicity in primary cultured rat hepatocytes[98] Further studies also demonstrated that the protectiveeffects of saikosaponins isolated from Bupleurum chinenseDC could prevent hepatocyte injury through regulatingintracellular calcium levels [99] In a rat model with CCl4induced acute hepatic injury the hepatic enzyme levels (GOTGPT and ALP) and the lipid peroxidation in the liver weresignificantly reduced by the administration of SSd [100]Additionally SSd significantly reduced collagen I depositionand alanine aminotransferase level on liver fibrosis rats anddecreased the concentration of transforming growth factor1205731 (TGF-1205731) Moreover SSd was able to alleviate hepatocyteinjury from oxidative stressThe effect of SSd on liver fibrosismay be related to its ability to reduce lipid peroxidation [101]

57 Immunomodulatory Effects Yamakage et al determinedthe effects of Radix Bupleuri on spontaneous lymphaticvessel activity The results indicated that Radix Bupleurisignificantly increased the amplitude of spontaneous activityof lymphatic vessels in a concentration-dependent mannerand the mechanisms of this effect seem to be independent ofendothelial function [102] Eugenin (46) and saikochrome A(47) isolated from the MeOH extracts from Bupleurum scor-zonerifolium possessed immunosuppressive effect on humanperipheral blood T cells via inhibiting CD28-costimulatedactivation [62] SSd (10mg intraperitoneally) significantlyactivated peritoneal macrophages in terms of enhancementof phagocytic activity increased level of cellular lysosomalenzyme and suppressed the response of plaque-forming cellsto heterologous erythrocytes by stimulating T and B cells ina dose-dependent manner [103] Moreover SSd modulated

lymphocyte activity through suppressing the T cell responseand increasing the B cell response to different mitogensand the interleukin- (IL-) 2IL-4 production through areceptor-bypassed pathway [41 104 105] In another exper-iment Wong et al found that SSd was shown to inhibitOKT3CD28-costimulated human T cell proliferation andPMA PMAionomycin and Con A-induced mouse T cellactivation in vitro The underlying mechanisms involveddownregulation of NF-kB signaling by suppression of IKKand Akt activities [106]

58 Autophagic Effect Autophagy is a complex processin cells which occurs through the formation of double-membrane vesicles (autophagosomes) which are engulfedby cytoplasmic molecules Then the autophagosome fuseswith the lysosomes leading to degradation of long-livedproteins aggregated proteins and damaged organelles [107ndash109] Moreover autophagy might be triggered by hypoxianutritional deprivation radiation chemical drugs and otherstimulants [110] Autophagy contributes to the pathogenesisof diverse diseases such as neuronal degeneration inflamma-tory bowel disease aging and cancer [111 112] In the previousstudy Law et al demonstrated that the protective pharma-cological effects of Radix Bupleuri might be attributed to itsautophagy inductionThe autophagic effect of Radix Bupleuriplayed an important role in relieving liver disease-relatedsymptoms through anti-inflammatory organ-protective andaggregate removal functions Furthermore the anticancereffects of Radix Bupleuri could be attributed to its autophagyinduction Radix Bupleuri has been found to be an effectivetreatment against depression by regulating metabolite hor-mone and neurotransmitter levels via autophagy-mediatedlipid metabolism [113]

59 Other Pharmacological Effects The effect of the ethanolextract from Radix Bupleuri on cytochrome 450 isoformactivities using a six-drug cocktail approach was evaluatedthe results demonstrated that Radix Bupleuri had stronginduction activity on the CYP2E1 CYP2D6 and CYP3A4which may lead to potential plant drug-drug interactions[114] Radix Bupleuri was shown to be the inhibitor of 120573-glucuronidase The inhibition rate of Radix Bupleuri extractsRB1 (high molecular weight polysaccharides) RB2 (ethanolsolublewater insoluble component) RB3 (extracted by n-butanol soluble in water) and RB4 (low molecular weightwater soluble parts) on the activity of 120573-glucuronidase wasfound to be 4515 3394 2494 and 3454 respectively[115] In pentylenetetrazol (PTZ) induced epilepsy ratsmodelSSa isolated fromRadix Bupleuri significantly reduced seizureseverity and duration while it markedly elevated seizurelatency and downregulated the cytokines expression of p-mTOR p-70S6K L-1120573 and TNF-120572 through inhibitingmTORsignaling pathway [116] He et al demonstrated that SSa obvi-ously reduced lipoprotein uptake to block foamcell formationand the expression of LOX-1 and CD36 boosted cholesterolefflux and the expression of ABCA1 and PPAR120574 throughinhibiting PI3KAktNF-120581BNLRP3 signaling pathway [117]

In another experiment SSc exerted a potent effect on induc-ing human umbilical vein endothelial cells (HUVECs) via-bility and growth Furthermore SSc also induced endothelialcells migration and capillary tube formation The underlyingmechanisms might be related to the gene expression oractivation of matrix metalloproteinase-2 (MMP-2) vascularendothelial growth factor (VEGF) and the p42p44mitogen-activated protein kinase (MAPK ERK) [118] In addition SScwas shown to exhibit inhibitory activities against Alzheimerrsquosdisease (AD) via suppressing the secretion ofA120573 peptides andabnormal tau hyperphosphorylation-mediated microtubuledepolymerization Moreover SSc suppressed A120573 peptide-induced brain endothelial apoptosis indicating that Sscmight be a novel therapeutic tool for treating human AD andother neurodegenerative diseases [119] It was shown by Liuet al for the first time that four polyacetylenes (36ndash39) fromRadix Bupleuri potently exhibited an antidepressant activityby inhibiting the reuptake of serotonin norepinephrine anddopamine The mechanism might be mediated by increasingthe level of monoamines particularly 5-HT andNE [56] Zhuet al suggested that SSa and SSd exhibited the anthelminticactivity against Dactylogyrus spp infecting goldfish Theeffective concentration (EC50) values for SSa and SSd were146 and 074mgminus1 respectively [120]

510 Summary of Pharmacological Effects Radix Bupleuripossesses awide spectrumof pharmacological effects includ-ing anti-inflammatory effect anticancer effect antiviraleffect antipyretic effect antibacterial effect hepatoprotectiveeffect and immunomodulatory effect (Table 3) Based onthese pharmacological effects we can conclude that theextracts and the compounds from this plant can preventor treat certain diseases such as cancer fever malariahepatitis and AD However there is not enough systemicdata of these chemical compounds and their pharmacologicaleffects Thus in the future the pharmacological effects andthe possible molecular mechanisms of the pharmacologicalactivities of Radix Bupleurimust be urgently explored on ourmodern understanding of these diseasesrsquo pathophysiologies

6 Toxicology

Radix Bupleuri has been used for thousands of years asan important traditional herb in China However the toxiceffects of Radix Bupleuri in clinical applications have beengradually reported Several studies have found that the liveris the main organ affected by toxicity particularly in long-term use Major symptoms of liver injury induced by RadixBupleuri included transaminase lifts hepatitis and jaundiceHowever liver functions can return to normal levels aftera specific period [121] Radix Bupleuri has been reportedto exhibit acute hepatitis and acute hepatic necrosis Themean total daily dose was 180 plusmn 335 g which was morethan the Chinese Pharmacopoeia recommended range of 3to 10 g [122] Moreover Radix Bupleuri had been implicatedinmultiple cases of acute hepatitis both as an ingredient aloneand within a particular formulation ldquoXiao-Chai-Hu-Tangrdquo(also known as Syo-Saiko-To in Japanese) [123] Lee et al

demonstrated that two Chinese herbal products containingRadix Bupleuri might increase their risks of liver injuryin HBV-infected patients However further mechanisticresearch on the hepatotoxicity of Radix Bupleuri in thepresence ofHBV infection is warranted [124] In addition theessential oil of Radix Bupleuri induced acute hepatotoxicitywith asynchronous state higher heart rate and fast breathing[125] The total saponins isolated from Radix Bupleuri couldalso cause evidently liver damage in dose-dependent mannermanifested as hepatocyte organic lesion and liver functionchanges as well as hepatocyte death [126]

7 Pharmacokinetics

A selective and sensitive LC-MSMS method was developedand validated for simultaneous determination of SSa b2 cand d in rat plasma afteroral administration of the ethanol-water (50 50 vv) extract of Radix Bupleuri for the firsttime The results demonstrated that SSa c and d wereabsorbed rapidly with 119879max less than 30min [127] In anotherpharmacokinetics experiment of rats Liu et al was the first todevelop an UPLC-PDA-MS method to determine the phar-macokinetics of four polyacetylenes after ig administrationof 95 ethanol extract of Radix Bupleuri The results showedthat compounds 36 and 38 were not detected in rat serumwhereas compounds 37 and 39 exerted a fast distributionphase followed by a relatively slow elimination phase (119905121199114ndash7 h) [56]

8 Future Perspectives and Conclusions

In traditional Chinese medicine Radix Bupleuri has longbeen used regulate the exterior and interiormetabolisms dis-perse evil heat from superficies sooth the liver and promoteyang and qi It has been widely used to treat various diseasesin China Japan Korea and other Asian countries for manycenturies A total of 74 compounds including essential oilstriterpenoid saponins polyacetylenes flavonoids lignansfatty acids and sterols have been isolated and identifiedfrom Radix Bupleuri [39ndash65] Pharmacological studies haverevealed that Radix Bupleuri possesses a variety of biologicaleffects including anti-inflammatory anticancer antiviralantipyretic antibacterial antiobesity immunomodulatoryhepatoprotective neuroprotective and autophagic effects[66ndash120] However there are some aspects that need to befurther investigated

Radix Bupleuri is an ingredient of many patent medicinesor prescriptions Although modern experiments have con-firmed that this drug alone exhibits multiple pharmacolog-ical activities it is important to investigate the molecularmechanisms of Radix Bupleuri combined with other herbsbased on traditional uses Furthermore the pharmacologicaleffects of only a few of the ingredients such as saikosaponinsflavonoids and the essential oils have been investigatedSome polyacetylenes lignans and sterols have not beensufficiently researched in terms of their pharmacologicaleffects Radix Bupleuri shows both hepatoprotection and

hepatotoxicity which appears to be contradictory This phe-nomenon is similar to that of PolygonummultiflorumThunb[128] Based on the literature the main reasons are likelythe administration dosage and delivery time High doses andlong-term drug delivery are more likely to result in livertoxicity whereas low doses and short-term drug deliverymight result in liver protection Therefore this issue needsfurther study

In conclusion this review summarized the traditionaluses botany phytochemistry pharmacology and toxicologyof Radix Bupleuri Moreover it has provided a new founda-tion for further research on its mechanism of action and thedevelopment of better therapeutic agents employing RadixBupleuri in the future It is anticipated that the comprehen-sive and detailed research on toxicity pharmacodynamicspharmacokinetics and molecular mechanism are necessaryto be explored to develop its bioactive compounds as effectivedrugs

value was 60Mm [93] Saikosaponins isolated from RadixBupleuri have been reported to exhibit antibacterial activityparticularly against Pseudomonas aeruginosa and Listeriamonocytogenes The protective effect was attributed to theimmunomodulatory action on macrophages [94] ldquoChaihuinjectionrdquo has also been tested for possible antimicrobialactivity in vitroThe results demonstrated thatmild inhibitionof Staphylococcus aureus was observed but no effects wereobserved against Staphylococcus albusNeisseria gonorrhoeaeDiplococcus pneumoniae haemolytic Streptococcus or Pseu-domonas aeruginosa [95]

56 Hepatoprotective Effects The liver protective effectsagainst CCl4 induced liver injury were investigated aftertreatment ofmicewith raw and vinegar-bakedRadix Bupleuri(5 gkgday) for 14 days The results showed that both rawand processed Radix Bupleuri showed liver protective effectsagainst CCl4 induced liver injury and the vinegar-bakedRadix Bupleuri exerted better effects than that of raw RadixBupleuri [96] Pretreated with saikosaponins especially SSaor SSd showed remarkable inhibition of D-galactosamine-induced hepatic injury through decreasing the activity ofglucose-6-phosphatase and NADPH-cytochrome C reduc-tase and increasing 51015840-nucleotidase activity [97] Similarlybupleurosides III VI IX and XIII and saikosaponin b3isolated from Bupleurum scorzonerifolium Willd were alsofound to exhibit protective effect on the D-galactosamine-induced cytotoxicity in primary cultured rat hepatocytes[98] Further studies also demonstrated that the protectiveeffects of saikosaponins isolated from Bupleurum chinenseDC could prevent hepatocyte injury through regulatingintracellular calcium levels [99] In a rat model with CCl4induced acute hepatic injury the hepatic enzyme levels (GOTGPT and ALP) and the lipid peroxidation in the liver weresignificantly reduced by the administration of SSd [100]Additionally SSd significantly reduced collagen I depositionand alanine aminotransferase level on liver fibrosis rats anddecreased the concentration of transforming growth factor1205731 (TGF-1205731) Moreover SSd was able to alleviate hepatocyteinjury from oxidative stressThe effect of SSd on liver fibrosismay be related to its ability to reduce lipid peroxidation [101]

57 Immunomodulatory Effects Yamakage et al determinedthe effects of Radix Bupleuri on spontaneous lymphaticvessel activity The results indicated that Radix Bupleurisignificantly increased the amplitude of spontaneous activityof lymphatic vessels in a concentration-dependent mannerand the mechanisms of this effect seem to be independent ofendothelial function [102] Eugenin (46) and saikochrome A(47) isolated from the MeOH extracts from Bupleurum scor-zonerifolium possessed immunosuppressive effect on humanperipheral blood T cells via inhibiting CD28-costimulatedactivation [62] SSd (10mg intraperitoneally) significantlyactivated peritoneal macrophages in terms of enhancementof phagocytic activity increased level of cellular lysosomalenzyme and suppressed the response of plaque-forming cellsto heterologous erythrocytes by stimulating T and B cells ina dose-dependent manner [103] Moreover SSd modulated

lymphocyte activity through suppressing the T cell responseand increasing the B cell response to different mitogensand the interleukin- (IL-) 2IL-4 production through areceptor-bypassed pathway [41 104 105] In another exper-iment Wong et al found that SSd was shown to inhibitOKT3CD28-costimulated human T cell proliferation andPMA PMAionomycin and Con A-induced mouse T cellactivation in vitro The underlying mechanisms involveddownregulation of NF-kB signaling by suppression of IKKand Akt activities [106]

58 Autophagic Effect Autophagy is a complex processin cells which occurs through the formation of double-membrane vesicles (autophagosomes) which are engulfedby cytoplasmic molecules Then the autophagosome fuseswith the lysosomes leading to degradation of long-livedproteins aggregated proteins and damaged organelles [107ndash109] Moreover autophagy might be triggered by hypoxianutritional deprivation radiation chemical drugs and otherstimulants [110] Autophagy contributes to the pathogenesisof diverse diseases such as neuronal degeneration inflamma-tory bowel disease aging and cancer [111 112] In the previousstudy Law et al demonstrated that the protective pharma-cological effects of Radix Bupleuri might be attributed to itsautophagy inductionThe autophagic effect of Radix Bupleuriplayed an important role in relieving liver disease-relatedsymptoms through anti-inflammatory organ-protective andaggregate removal functions Furthermore the anticancereffects of Radix Bupleuri could be attributed to its autophagyinduction Radix Bupleuri has been found to be an effectivetreatment against depression by regulating metabolite hor-mone and neurotransmitter levels via autophagy-mediatedlipid metabolism [113]

59 Other Pharmacological Effects The effect of the ethanolextract from Radix Bupleuri on cytochrome 450 isoformactivities using a six-drug cocktail approach was evaluatedthe results demonstrated that Radix Bupleuri had stronginduction activity on the CYP2E1 CYP2D6 and CYP3A4which may lead to potential plant drug-drug interactions[114] Radix Bupleuri was shown to be the inhibitor of 120573-glucuronidase The inhibition rate of Radix Bupleuri extractsRB1 (high molecular weight polysaccharides) RB2 (ethanolsolublewater insoluble component) RB3 (extracted by n-butanol soluble in water) and RB4 (low molecular weightwater soluble parts) on the activity of 120573-glucuronidase wasfound to be 4515 3394 2494 and 3454 respectively[115] In pentylenetetrazol (PTZ) induced epilepsy ratsmodelSSa isolated fromRadix Bupleuri significantly reduced seizureseverity and duration while it markedly elevated seizurelatency and downregulated the cytokines expression of p-mTOR p-70S6K L-1120573 and TNF-120572 through inhibitingmTORsignaling pathway [116] He et al demonstrated that SSa obvi-ously reduced lipoprotein uptake to block foamcell formationand the expression of LOX-1 and CD36 boosted cholesterolefflux and the expression of ABCA1 and PPAR120574 throughinhibiting PI3KAktNF-120581BNLRP3 signaling pathway [117]

In another experiment SSc exerted a potent effect on induc-ing human umbilical vein endothelial cells (HUVECs) via-bility and growth Furthermore SSc also induced endothelialcells migration and capillary tube formation The underlyingmechanisms might be related to the gene expression oractivation of matrix metalloproteinase-2 (MMP-2) vascularendothelial growth factor (VEGF) and the p42p44mitogen-activated protein kinase (MAPK ERK) [118] In addition SScwas shown to exhibit inhibitory activities against Alzheimerrsquosdisease (AD) via suppressing the secretion ofA120573 peptides andabnormal tau hyperphosphorylation-mediated microtubuledepolymerization Moreover SSc suppressed A120573 peptide-induced brain endothelial apoptosis indicating that Sscmight be a novel therapeutic tool for treating human AD andother neurodegenerative diseases [119] It was shown by Liuet al for the first time that four polyacetylenes (36ndash39) fromRadix Bupleuri potently exhibited an antidepressant activityby inhibiting the reuptake of serotonin norepinephrine anddopamine The mechanism might be mediated by increasingthe level of monoamines particularly 5-HT andNE [56] Zhuet al suggested that SSa and SSd exhibited the anthelminticactivity against Dactylogyrus spp infecting goldfish Theeffective concentration (EC50) values for SSa and SSd were146 and 074mgminus1 respectively [120]

510 Summary of Pharmacological Effects Radix Bupleuripossesses awide spectrumof pharmacological effects includ-ing anti-inflammatory effect anticancer effect antiviraleffect antipyretic effect antibacterial effect hepatoprotectiveeffect and immunomodulatory effect (Table 3) Based onthese pharmacological effects we can conclude that theextracts and the compounds from this plant can preventor treat certain diseases such as cancer fever malariahepatitis and AD However there is not enough systemicdata of these chemical compounds and their pharmacologicaleffects Thus in the future the pharmacological effects andthe possible molecular mechanisms of the pharmacologicalactivities of Radix Bupleurimust be urgently explored on ourmodern understanding of these diseasesrsquo pathophysiologies

6 Toxicology

Radix Bupleuri has been used for thousands of years asan important traditional herb in China However the toxiceffects of Radix Bupleuri in clinical applications have beengradually reported Several studies have found that the liveris the main organ affected by toxicity particularly in long-term use Major symptoms of liver injury induced by RadixBupleuri included transaminase lifts hepatitis and jaundiceHowever liver functions can return to normal levels aftera specific period [121] Radix Bupleuri has been reportedto exhibit acute hepatitis and acute hepatic necrosis Themean total daily dose was 180 plusmn 335 g which was morethan the Chinese Pharmacopoeia recommended range of 3to 10 g [122] Moreover Radix Bupleuri had been implicatedinmultiple cases of acute hepatitis both as an ingredient aloneand within a particular formulation ldquoXiao-Chai-Hu-Tangrdquo(also known as Syo-Saiko-To in Japanese) [123] Lee et al

demonstrated that two Chinese herbal products containingRadix Bupleuri might increase their risks of liver injuryin HBV-infected patients However further mechanisticresearch on the hepatotoxicity of Radix Bupleuri in thepresence ofHBV infection is warranted [124] In addition theessential oil of Radix Bupleuri induced acute hepatotoxicitywith asynchronous state higher heart rate and fast breathing[125] The total saponins isolated from Radix Bupleuri couldalso cause evidently liver damage in dose-dependent mannermanifested as hepatocyte organic lesion and liver functionchanges as well as hepatocyte death [126]

7 Pharmacokinetics

A selective and sensitive LC-MSMS method was developedand validated for simultaneous determination of SSa b2 cand d in rat plasma afteroral administration of the ethanol-water (50 50 vv) extract of Radix Bupleuri for the firsttime The results demonstrated that SSa c and d wereabsorbed rapidly with 119879max less than 30min [127] In anotherpharmacokinetics experiment of rats Liu et al was the first todevelop an UPLC-PDA-MS method to determine the phar-macokinetics of four polyacetylenes after ig administrationof 95 ethanol extract of Radix Bupleuri The results showedthat compounds 36 and 38 were not detected in rat serumwhereas compounds 37 and 39 exerted a fast distributionphase followed by a relatively slow elimination phase (119905121199114ndash7 h) [56]

8 Future Perspectives and Conclusions

In traditional Chinese medicine Radix Bupleuri has longbeen used regulate the exterior and interiormetabolisms dis-perse evil heat from superficies sooth the liver and promoteyang and qi It has been widely used to treat various diseasesin China Japan Korea and other Asian countries for manycenturies A total of 74 compounds including essential oilstriterpenoid saponins polyacetylenes flavonoids lignansfatty acids and sterols have been isolated and identifiedfrom Radix Bupleuri [39ndash65] Pharmacological studies haverevealed that Radix Bupleuri possesses a variety of biologicaleffects including anti-inflammatory anticancer antiviralantipyretic antibacterial antiobesity immunomodulatoryhepatoprotective neuroprotective and autophagic effects[66ndash120] However there are some aspects that need to befurther investigated

Radix Bupleuri is an ingredient of many patent medicinesor prescriptions Although modern experiments have con-firmed that this drug alone exhibits multiple pharmacolog-ical activities it is important to investigate the molecularmechanisms of Radix Bupleuri combined with other herbsbased on traditional uses Furthermore the pharmacologicaleffects of only a few of the ingredients such as saikosaponinsflavonoids and the essential oils have been investigatedSome polyacetylenes lignans and sterols have not beensufficiently researched in terms of their pharmacologicaleffects Radix Bupleuri shows both hepatoprotection and

hepatotoxicity which appears to be contradictory This phe-nomenon is similar to that of PolygonummultiflorumThunb[128] Based on the literature the main reasons are likelythe administration dosage and delivery time High doses andlong-term drug delivery are more likely to result in livertoxicity whereas low doses and short-term drug deliverymight result in liver protection Therefore this issue needsfurther study

In conclusion this review summarized the traditionaluses botany phytochemistry pharmacology and toxicologyof Radix Bupleuri Moreover it has provided a new founda-tion for further research on its mechanism of action and thedevelopment of better therapeutic agents employing RadixBupleuri in the future It is anticipated that the comprehen-sive and detailed research on toxicity pharmacodynamicspharmacokinetics and molecular mechanism are necessaryto be explored to develop its bioactive compounds as effectivedrugs

In another experiment SSc exerted a potent effect on induc-ing human umbilical vein endothelial cells (HUVECs) via-bility and growth Furthermore SSc also induced endothelialcells migration and capillary tube formation The underlyingmechanisms might be related to the gene expression oractivation of matrix metalloproteinase-2 (MMP-2) vascularendothelial growth factor (VEGF) and the p42p44mitogen-activated protein kinase (MAPK ERK) [118] In addition SScwas shown to exhibit inhibitory activities against Alzheimerrsquosdisease (AD) via suppressing the secretion ofA120573 peptides andabnormal tau hyperphosphorylation-mediated microtubuledepolymerization Moreover SSc suppressed A120573 peptide-induced brain endothelial apoptosis indicating that Sscmight be a novel therapeutic tool for treating human AD andother neurodegenerative diseases [119] It was shown by Liuet al for the first time that four polyacetylenes (36ndash39) fromRadix Bupleuri potently exhibited an antidepressant activityby inhibiting the reuptake of serotonin norepinephrine anddopamine The mechanism might be mediated by increasingthe level of monoamines particularly 5-HT andNE [56] Zhuet al suggested that SSa and SSd exhibited the anthelminticactivity against Dactylogyrus spp infecting goldfish Theeffective concentration (EC50) values for SSa and SSd were146 and 074mgminus1 respectively [120]

510 Summary of Pharmacological Effects Radix Bupleuripossesses awide spectrumof pharmacological effects includ-ing anti-inflammatory effect anticancer effect antiviraleffect antipyretic effect antibacterial effect hepatoprotectiveeffect and immunomodulatory effect (Table 3) Based onthese pharmacological effects we can conclude that theextracts and the compounds from this plant can preventor treat certain diseases such as cancer fever malariahepatitis and AD However there is not enough systemicdata of these chemical compounds and their pharmacologicaleffects Thus in the future the pharmacological effects andthe possible molecular mechanisms of the pharmacologicalactivities of Radix Bupleurimust be urgently explored on ourmodern understanding of these diseasesrsquo pathophysiologies

6 Toxicology

Radix Bupleuri has been used for thousands of years asan important traditional herb in China However the toxiceffects of Radix Bupleuri in clinical applications have beengradually reported Several studies have found that the liveris the main organ affected by toxicity particularly in long-term use Major symptoms of liver injury induced by RadixBupleuri included transaminase lifts hepatitis and jaundiceHowever liver functions can return to normal levels aftera specific period [121] Radix Bupleuri has been reportedto exhibit acute hepatitis and acute hepatic necrosis Themean total daily dose was 180 plusmn 335 g which was morethan the Chinese Pharmacopoeia recommended range of 3to 10 g [122] Moreover Radix Bupleuri had been implicatedinmultiple cases of acute hepatitis both as an ingredient aloneand within a particular formulation ldquoXiao-Chai-Hu-Tangrdquo(also known as Syo-Saiko-To in Japanese) [123] Lee et al

demonstrated that two Chinese herbal products containingRadix Bupleuri might increase their risks of liver injuryin HBV-infected patients However further mechanisticresearch on the hepatotoxicity of Radix Bupleuri in thepresence ofHBV infection is warranted [124] In addition theessential oil of Radix Bupleuri induced acute hepatotoxicitywith asynchronous state higher heart rate and fast breathing[125] The total saponins isolated from Radix Bupleuri couldalso cause evidently liver damage in dose-dependent mannermanifested as hepatocyte organic lesion and liver functionchanges as well as hepatocyte death [126]

7 Pharmacokinetics

A selective and sensitive LC-MSMS method was developedand validated for simultaneous determination of SSa b2 cand d in rat plasma afteroral administration of the ethanol-water (50 50 vv) extract of Radix Bupleuri for the firsttime The results demonstrated that SSa c and d wereabsorbed rapidly with 119879max less than 30min [127] In anotherpharmacokinetics experiment of rats Liu et al was the first todevelop an UPLC-PDA-MS method to determine the phar-macokinetics of four polyacetylenes after ig administrationof 95 ethanol extract of Radix Bupleuri The results showedthat compounds 36 and 38 were not detected in rat serumwhereas compounds 37 and 39 exerted a fast distributionphase followed by a relatively slow elimination phase (119905121199114ndash7 h) [56]

8 Future Perspectives and Conclusions

In traditional Chinese medicine Radix Bupleuri has longbeen used regulate the exterior and interiormetabolisms dis-perse evil heat from superficies sooth the liver and promoteyang and qi It has been widely used to treat various diseasesin China Japan Korea and other Asian countries for manycenturies A total of 74 compounds including essential oilstriterpenoid saponins polyacetylenes flavonoids lignansfatty acids and sterols have been isolated and identifiedfrom Radix Bupleuri [39ndash65] Pharmacological studies haverevealed that Radix Bupleuri possesses a variety of biologicaleffects including anti-inflammatory anticancer antiviralantipyretic antibacterial antiobesity immunomodulatoryhepatoprotective neuroprotective and autophagic effects[66ndash120] However there are some aspects that need to befurther investigated

Radix Bupleuri is an ingredient of many patent medicinesor prescriptions Although modern experiments have con-firmed that this drug alone exhibits multiple pharmacolog-ical activities it is important to investigate the molecularmechanisms of Radix Bupleuri combined with other herbsbased on traditional uses Furthermore the pharmacologicaleffects of only a few of the ingredients such as saikosaponinsflavonoids and the essential oils have been investigatedSome polyacetylenes lignans and sterols have not beensufficiently researched in terms of their pharmacologicaleffects Radix Bupleuri shows both hepatoprotection and

hepatotoxicity which appears to be contradictory This phe-nomenon is similar to that of PolygonummultiflorumThunb[128] Based on the literature the main reasons are likelythe administration dosage and delivery time High doses andlong-term drug delivery are more likely to result in livertoxicity whereas low doses and short-term drug deliverymight result in liver protection Therefore this issue needsfurther study

In conclusion this review summarized the traditionaluses botany phytochemistry pharmacology and toxicologyof Radix Bupleuri Moreover it has provided a new founda-tion for further research on its mechanism of action and thedevelopment of better therapeutic agents employing RadixBupleuri in the future It is anticipated that the comprehen-sive and detailed research on toxicity pharmacodynamicspharmacokinetics and molecular mechanism are necessaryto be explored to develop its bioactive compounds as effectivedrugs

hepatotoxicity which appears to be contradictory This phe-nomenon is similar to that of PolygonummultiflorumThunb[128] Based on the literature the main reasons are likelythe administration dosage and delivery time High doses andlong-term drug delivery are more likely to result in livertoxicity whereas low doses and short-term drug deliverymight result in liver protection Therefore this issue needsfurther study

In conclusion this review summarized the traditionaluses botany phytochemistry pharmacology and toxicologyof Radix Bupleuri Moreover it has provided a new founda-tion for further research on its mechanism of action and thedevelopment of better therapeutic agents employing RadixBupleuri in the future It is anticipated that the comprehen-sive and detailed research on toxicity pharmacodynamicspharmacokinetics and molecular mechanism are necessaryto be explored to develop its bioactive compounds as effectivedrugs

hepatotoxicity which appears to be contradictory This phe-nomenon is similar to that of PolygonummultiflorumThunb[128] Based on the literature the main reasons are likelythe administration dosage and delivery time High doses andlong-term drug delivery are more likely to result in livertoxicity whereas low doses and short-term drug deliverymight result in liver protection Therefore this issue needsfurther study

In conclusion this review summarized the traditionaluses botany phytochemistry pharmacology and toxicologyof Radix Bupleuri Moreover it has provided a new founda-tion for further research on its mechanism of action and thedevelopment of better therapeutic agents employing RadixBupleuri in the future It is anticipated that the comprehen-sive and detailed research on toxicity pharmacodynamicspharmacokinetics and molecular mechanism are necessaryto be explored to develop its bioactive compounds as effectivedrugs

hepatotoxicity which appears to be contradictory This phe-nomenon is similar to that of PolygonummultiflorumThunb[128] Based on the literature the main reasons are likelythe administration dosage and delivery time High doses andlong-term drug delivery are more likely to result in livertoxicity whereas low doses and short-term drug deliverymight result in liver protection Therefore this issue needsfurther study

In conclusion this review summarized the traditionaluses botany phytochemistry pharmacology and toxicologyof Radix Bupleuri Moreover it has provided a new founda-tion for further research on its mechanism of action and thedevelopment of better therapeutic agents employing RadixBupleuri in the future It is anticipated that the comprehen-sive and detailed research on toxicity pharmacodynamicspharmacokinetics and molecular mechanism are necessaryto be explored to develop its bioactive compounds as effectivedrugs

hepatotoxicity which appears to be contradictory This phe-nomenon is similar to that of PolygonummultiflorumThunb[128] Based on the literature the main reasons are likelythe administration dosage and delivery time High doses andlong-term drug delivery are more likely to result in livertoxicity whereas low doses and short-term drug deliverymight result in liver protection Therefore this issue needsfurther study

In conclusion this review summarized the traditionaluses botany phytochemistry pharmacology and toxicologyof Radix Bupleuri Moreover it has provided a new founda-tion for further research on its mechanism of action and thedevelopment of better therapeutic agents employing RadixBupleuri in the future It is anticipated that the comprehen-sive and detailed research on toxicity pharmacodynamicspharmacokinetics and molecular mechanism are necessaryto be explored to develop its bioactive compounds as effectivedrugs
