1 INTRODUCTION

Rheumatoid arthritis (RA) is a chronic multisystem disease of unknown cause Though the

most prominent manifestation of RA is inflammatory arthritis of the peripheral joints usually

with a symmetrical distribution its systemic manifestations include haematologic

pulmonary neurological and cardiovascular abnormalities RA is a common disease having

peak incidence in 3rd to 4th decades of life with 3-5 times higher preponderance in females

Approximately 20 of patients develop rheumatoid nodules located over the extensor

surfaces of the elbows and fingers About 80 of cases are seropositive for rheumatoid factor

(RF) However RF titres are elevated in certain unrelated diseases too such as in viral

hepatitis cirrhosis sarcoidosis and leprosy Advanced cases show characteristic radiologic

abnormalities such as narrowing of joint space and ulnar deviation of the fingers and radial

deviation of the wrist

Etiopathogenesis Present concept on etiology and pathogenesis proposes that RA occurs in

an immunogenetically predisposed individual to the effect of microbial agents acting as

trigger antigen The role of super antigens which are produced by several microorganisms

with capacity to bind to HLADR molecules (MHC-II region) has also emerged I

Immunologic derangements II Trigger events

The proposed events in immunopathogenesis of RA are

In response to antigenic exposure (eg infectious agent) in a genetically predisposed

individual (HLA-DR) CD4+ T cells are activated

These cells elaborate cytokines the important ones being tumour necrosis factor (TNF)

interferon (IF) interleukin (IL)-1 and IL-6

These cytokines activate endothelial cells B lymphocytes and macrophages

Activation of B-cells releases IgM antibody against IgG (ie anti-IgG) this molecule is

termed rheumatoid factor (RF)

IgG and IgM immune complexes trigger inflammatory damage to the synovium small

blood vessels and collagen

Activated endothelial cells express adhesion molecules which stimulate collection of

inflammatory cells

Activation of macrophages releases more cytokines which cause damage to joint tissues

and vascularisation of cartilage termed pannus formation

Rizwan et al World Journal of Pharmaceutical Research

wwwwjprnet Vol 9 Issue 1 2020

1184

Eventually damage and destruction of bone and cartilage are followed by fibrosis and

ankylosis producing joint deformities

Fig 11 Pathogenesis of RA

Morphologic Features The predominant pathologic lesions are found in the joints and

tendons and less often extra-articular lesions are encountered

Articular Lesions RA involves first the small joints of hands and feet and then

symmetrically affects the joints of wrists elbows ankles and knees The proximal

interphalangeal and metacarpophalangeal joints are affected most severely Frequently

cervical spine is involved but lumbar spine is spared

Rizwan et al World Journal of Pharmaceutical Research

wwwwjprnet Vol 9 Issue 1 2020

1185

Histologically the characteristic feature is diffuse proliferative synovitis with formation of

pannus The microscopic changes are as under

1 Numerous folds of large villi of synovium

2 Marked thickening of the synovial membrane due to oedema congestion and

multilayering of synoviocytes

3 Intense inflammatory cell infiltrate in the synovial membrane with predominance of

lymphocytes plasma cells and some macrophages at places forming lymphoid follicles

Fig 12 The characteristic histologic features are villous hypertrophy of the synovium

and marked mononuclear inflammatory cell infiltrate in synovial membrane with

formation of lymphoid follicles at places

4 Foci of fibrinoid necrosis and fibrin deposition The pannus progressively destroys the

underlying cartilage and subchondral bone This invasion of pannus results in

demineralisation and cystic resorption of underlying bone Later fibrous adhesions or even

bony ankylosis may unite the two opposing joint surfaces In addition persistent

inflammation causes weakening and even rupture of the tendons

Extra-Articular Lesions Nonspecific inflammatory changes are seen in the blood vessels

(acute vasculitis) lungs pleura pericardium myocardium lymph nodes peripheral nerves

and eyes But one of the characteristic extra-articular manifestations of RA is occurrence of

rheumatoid nodules in the skin Rheumatoid nodules are particularly found in the

subcutaneous tissue over pressure points such as the elbows occiput and sacrum The centre

of these nodules consists of an area of fibrinoid necrosis and cellular debris surrounded by

several layers of palisading large epithelioid cells and peripherally there are numerous

Rizwan et al World Journal of Pharmaceutical Research

wwwwjprnet Vol 9 Issue 1 2020

1186

lymphocytes plasma cells and macrophages Similar nodules may be found in the lung

parenchyma pleura heart valves myocardium and other internal organs

There are a few variant forms of RA

1 Juvenile RA found in adolescent patients less than 16 years of age is characterised by

acute onset of fever and predominant involvement of knees and ankles Pathologic changes

are similar but RF is rarely present

2 Feltyrsquos syndrome consists of polyarticular RA associated with splenomegaly and

hypersplenism and consequent haematologic derangements

3 Ankylosing spondylitis or rheumatoid spondylitis is rheumatoid involvement of the

spine particularly sacroiliac joints in young male patients The condition has a strong HLA-

B27 association and may have associated inflammatory diseases such as inflammatory bowel

disease anterior uveitis and Reiterrsquos syndrome

Present Therapy

The goal of rheumatoid arthritis treatment now aims toward achieving the lowest possible

level of arthritis disease activity and remission if possible minimizing joint damage and

enhancing physical function and quality of life The optimal treatment of RA requires a

comprehensive program that combines medical social and emotional support for the patient

It is essential that the patient and the patientrsquos family be educated about the nature and course

of the disease Treatment options include medications reduction of joint stress physical and

occupational therapy and surgical intervention[34]

Proposed Therapy

Herbal medicine provides another approach for treatment of RA and currently a number of

medicinal plants are under scientific evaluation to develop a novel drug There is a dire need

to investigate the complete therapeutic potential and adverse effects if any of these herbals

for providing newer and safer treatment options with minimum side effects

The proposed therapy represents the combination of the following two herbal medicines for

treatment of rheumatoid arthritis in gel form

Commiphora mukul (Guggul)

Boswellia serrata

Skin as a drug delivery target[22 23]

Human skin is essentially composed of two major layers an outer unvascularized epithelial

layer (the epidermis) which contains a rich supply of capillaries sweat glands nerves

sebaceous glands and hair follicles that are supported by connective tissue

Epidermis

It is the outermost multilayer of the skin Its thickness varies depending on number of cells it

contains and its position on the body The multilayered epidermis varies in thickness ranging

from about 08 mm on the palms and soles to 006 mm on the eyelids The different layers of

the epidermis represent the different stages of differentiation of stem cells migrating towards

the surface

Rizwan et al World Journal of Pharmaceutical Research

wwwwjprnet Vol 9 Issue 1 2020

1188

Fig 13 Component of the Epidermis and Dermis of Human Skin

Moving downwards the epidermis is made up of five layers

Stratum corneum (horney layer)

Stratum granulosum (granular layer)

Stratum Malphigion (spin sumpigment layer)

Stratum granulosum (basal layer)

Stratum lucidum

The superficial layer of epidermis and also the final stage of differentiation the stratum

corneumis formed from several layer of dead cells embedded in the lipid matrix It is almost

impermeable and is important in controlling the percutaneous absorption of drugs and other

chemicals

Dermis

The dermis (corneum) 3-5 mm thick consist of matrix of connective tissue woven from

fibrous protein (collagen elastin and reticulin) that is embedded in an amorphous ground of

substances called as mucopolysaccharides nerves blood vessels and lymphaticrsquos traverse the

matrix and appendages pierce it It needs an efficient blood supply to convey nutrients

remove waste products regulate temperature and pressure mobilize skin force and contribute

to skin colour

Rizwan et al World Journal of Pharmaceutical Research

wwwwjprnet Vol 9 Issue 1 2020

1189

Subcutaneous Layer

The subcutaneous layer is beneath the dermis and consists mainly of a type of connective

tissue called Adipose tissue Adipose tissue is more commonly known as fat and helps

cushion the skin and provide protection from cold and temperature fluctuations

Rational approaches to drug delivery in the skin

There are two main ways to attack the problem of formulating a successful topical dosage

form

Directing drugs to the viable skin tissue without using oral systemic or other routes of

therapy

The other approaches use skin delivery for systemic treatment For example transdermal

therapeutic system provides systemic therapy for conditions such as motion sickness and

pain

Gels[13]

Topical gel formulations are of increasing interest in the dermatology industry Gel

formulations are typically transparent or translucent water-based semisolids with good

spreading properties and pleasing aesthetic characteristics

Delivery of drugs to the skin is an effective and targeted therapy for local dermatological

disorders This route of drug delivery has gained popularity because it avoids first pass

effects gastrointestinal irritation and metabolic degradation associated with oral

administration[5]

Due to the first past effect only 25-45 of the orally administered dose

reaches the blood circulation In order to bypass these disadvantages the gel formulations

have been proposed as topical application[6]

Topical gel formulations provide a suitable

delivery system for drugs because they are less greasy and can be easily removed from

the skin Percutaneous absorption of drugs from topical formulations involves the release

of the drug from the formulation and permeation through skin to reach the target tissue

The release of the drug from topical preparations depends on the physicochemical

properties of the vehicle and the drug employed In order to enhance drug release and skin

permeation methods such as the selection of a suitable vehicle co-administration of a

chemical enhancer[7]

have been studied Gel base formulation makes the drug molecules

more easily removable from the system than cream and ointment[89]

Gels for

dermatological use have several favorable properties such as being thixotropic

Rizwan et al World Journal of Pharmaceutical Research

wwwwjprnet Vol 9 Issue 1 2020

1190

greaseless easily spreadable easily removable emollient non-staining compatible with

several excipients and water-soluble or miscible[10]

Guggul and Boswellic acid when presented in the form of topical gel can reduce local

inflammations and arthritis Hence for local inflammation or pain in the body the topical

application of Guggul and Boswellic acid may be useful which also avoids the side

effects associated with the oral therapy Hence a topical gel containing Guggul and

Boswellic acid was prepared[11]

It is established that gel formulations are superior topical

formulation over any other topical formulations because these system have better

application property in comparison to creams and ointments[12]

In the present study the product which was selected is herbal gel The term gel oriented

during the late 1800rsquos as chemists attempted to classify semisolid substances according to

their molecule compositions At that time analytical method needed to determines

chemical structures were lacking Gels and jellies are composed of small amount of solid

dispersed in relatively large amount liquid yet they possess more solid like than liquid

like character In general gels and jellies are rigid enough to maintain their shapes under

a small applied stress

The United States Pharmacopoeia (USP) defines gels as semisolid being either

suspensions of small inorganic particles or large organic molecules interpenetrated with

liquid[14]

It is the interaction between units of the colloidal phase inorganic or organic

that set up the structural viscosity immobilizing liquid the continuous phase[15]

Thus gel

exhibit characteristics intermediate to those of liquid and solids[16]

Classification of gels

Gels are classified into different types based on the characteristics they possess[17]

1 Based on the nature of colloidal phase

a Inorganic gel - Examples Bentonite magma

b Organogel - Examples Polymer gel

These are further subdivided into different sub category according to chemicals nature of

dispersed organic molecules

Natural gums - Example Acacia Carrageenan Xanthan gum etc

Cellulosic derivatives - Examples Sodium carboxymethyl cellulose Hydroxyl ethyl

cellulose Hydroxyl propyl cellulose

Polyethylene and its co-polymer

used in weight loss formulae and is effective in reducing weight thus helping osteoarthritis

patients directly and indirectly It also reduces blood cholesterol levels Guggulsterone is a

plant chemical that has traditionally been used to treat osteoarthritis It may have anti-

inflammatory effects Part used- Exudate from bark or stem (Resins) Tribal people use the

twig of Guggul as a toothbrush because of its medicinal value Guggul is used to increase

metabolic rate in the ladies Because of anti-inflammatory nature Guggul is used to burn fat

in human bodies It increases bodyrsquos metabolic rate and reduces body fat Hence it is used

for weight loss It helps in functioning of the thyroid It has been proved of reducing breast

cancer It is used against heart diseases hence reduces stroke

Guggul has an excellent effect against rheumatism since centuries Guggul is effective

against painful menstruation It is also used in the treatment of leucorrhoea

Boswellia serrata have been traditionally used in folk medicine for centuries to treat various

chronic inflammatory diseases Part used-Extruded from stem (Resins) The resinous part

of Boswellia serrata possesses monoterpenes diterpenes triterpenes tetracyclic triterpenic

acids and four major pentacyclic triterpenic acids ie β-boswellic acid acetyl-β-boswellic

acid 11-keto-β-boswellic acid and acetyl-11-keto-β-boswellic acid responsible for inhibition

of pro-inflammatory enzymes Out of these four boswellic acids acetyl-11-keto-β-boswellic

acid is the most potent inhibitor of 5-lipoxygenase an enzyme responsible for inflammation

Evaluation of raw material[39]

The evaluations of the crude drug were carried out by testing following parameters

Total ash About 2 g of the air dried crude drug was weighed accurately in a tared silica

crucible and incinerated at a temperature not exceeding 450ordmC until free from carbon It was

then cooled and weighed A carbon free ash was not obtained in this way Then the charred

Rizwan et al World Journal of Pharmaceutical Research

1195

mass was exhausted with hot water the residue was collected on an ashless filter paper the

residue and the filter paper was incinerated until the ash was white or nearly so the filtrate

was added evaporated to dryness and ignited at a temperature not exceeding 450ordmC The

percentage of ash was calculated with reference to their air dried drug

Moisture content Water content is determined by removing the moisture and then by

measuring weight loss

Successive solvent extraction of resin[40]

The resin Commiphora mukul was taken and loaded in soxhlet extractor and extracted with

ethyl acetate about five times the weight of gum The temp is kept at 65-70degC The extracted

fluid is taken for solvent recovery The oleoresin (thick paste) obtained after solvent removal

was purified for enrichment of guggulsterones by solvent frication method 2 g sample of

guggul extract was taken in 250 mL round bottom flask 35 mL of 05 M alcoholic KOH was

added and reflux for 90 min on a water bath The content of flask was transferred to a

separator rinsed the flask with 50 mL lukewarm water Extracted while the liquid was warm

by shaking vigorously with three successive quantities of 50 mL petroleum ether (60-80deg)

Then combine the petroleum ether layers and wash with 20 mL water Evaporated the

petroleum ether and weighed the residue

Extraction Procedure

The collected resin was dried in a shade and powdered coarsely and was taken for soxhlet

extraction as shown in Figure 26

Preliminary phytochemical screening of petroleum ether extract of resin of commiphora

mukul[41]

The plants may be considered as a biosynthetic laboratory for a multitude of compounds like

alkaloids triterpenoids glycosides volatile oils tannins saponins sugars etc that exert

physiological effects These compounds are responsible for therapeutic effects usually the

secondary metabolites The petroleum extracts of Commiphora mukul was subjected to

preliminary phytochemical screening for the detection of various plant constituents The

different phytochemical test are as follows

Tests for sterols alkaloids saponins tannins flavonoids proteins amino acids sugars

Thin layer chromatography study[42 43]

Active extracts those having promising antimicrobial and antifungal activitywere subjected to

thin layer chromatography to find out the number of compounds present in them The details

of the procedure were as follows

A Preparation of the plates

The adsorbent used for thin layer chromatography was silica gel G About 25 g of silica gel G

was taken in a glass mortar and about 35 ml of distilled water was added to it This mixture

was then allowed to swell for 15 minutes The mixture was stirred with glass rod until it

becomes homogeneous Then an additional 15 ml of distilled water was added to it with

stirring The suspension was then transferred to a 150 ml flask fitted with a plastic stopper

and was shaken vigorously for about 2 minutes This suspension was then spreaded

immediately on thin layer chromatographic plates with the help of a thin layer

chromatography (TLC) applicator (SUPERFIT) of Continental Instruments Bombay was

used

B Drying and storage of plates

The freshly coated plates were then air dried until the transparency of the layer had

disappeared The plates were then stacked in a drying rack and were activated in an oven for

30 minutes at 110C The activated plates were then kept ina dessicator till required for

further use

C Application of the sample

For applying test samples on TLC plates glass capillaries were used The spots were applied

with the help of a fine capillary keeping a minimum distance of 1 cm between the two

adjacent spots The spots of the samples were marked on the top of the plate to know their

identity

1197

D Chromatographic chamber conditions of saturation and the development of TLC

plates

Chromatographic rectangular glass chamber (165 x 295 cm) was used in the experiments

To avoid insufficient chamber saturation and the undesirable edge effect a smooth sheet of

filter paper approximately of 15 x 40 cm size was placed in the chromatographic chamber in

a U shape and was allowed to be soaked in the developing solvent After being thus

moistened the paper was then pressed against the walls of the chamber so that it adhered to

the walls The chamber was allowed to saturate for 24 hours before use The experiments

were carried out at room temperature in diffused daylight

E Developing solvent system

A number of developing solvent systems were tried for each residue but the satisfactory

resolution was obtained in the solvent systems mentioned in table TLC results obtained in

these systems are as shown in Table 6

F Spraying equipment

Compressed air sprayer with a fine nozzle was used to detect the different constituents

present on TLC plates Air compressor was attached to a glass sprayer The sprayer was filled

with about 50 ml of the detection reagent and then used After each spray the sprayer was

washed separately with water chromic acid and distilled water and then with acetone

G Detection of The Spots

Spots were detected using UV light (UV Chamber) and spraying (50) H2SO4

Assay of Boswellia Serrata

Melting point

All the above studies were carried out by using no special equipement these were done by

visual assessment

Identification of Pure Drug

The thin layer chromatography (TLC) method is used to identification of isolated compound

to standard compound or marker in which the Rf value was noted

Solubility studies

A solubility study was carried out to find out the solubility of drug in different solvents

According to this method the pure drug was added to the solvent medium and shaken for 2

hr The saturation was confirmed by observation of presence of undissolved material After

filtration of the slurry sample was analyzed using UV Visible spectrophotometer at 252 - 255

nm

Formulation development[444546]

wooden block which was provided by a pulley at one end A rectangular ground glass plate

was fixed on this block An excess of gel (about 1 g) under the study was placed on this

ground plate The gel was then sandwiched between this plate and another glass plate having

the dimension of fixed ground plate and provided with the hook A 1 kg weight was placed

on the top of two plates for 5 minutes to expel air and to provide a uniform film of the gel

between the plates Excess of gel was scrapped off from the edges The top plate was then

subjected to pull of 10g with the help of string attached to the hook and the time (in second)

required by the top plate to cover a distance of 5 cm was noted

Skin irritancy test

This test was performed on human volunteers Twenty volunteers were chosen for single

formulation and study was performed after taking their informed consent It was performed

by applying gel on an area of 2 square inch to the back of hand Then the examination for the

presence of lesion or irritation was done

Drug Content Studies Accurately weighed 1 g of gel was transferred into 100 ml

volumetric flask containing 20 ml of saline phosphate buffer (pH 68) and stirred for 30 min

followed by sonication The volume was made up to 100 ml with saline phosphate buffer (pH

68) After suitable dilution the absorbance was measured using Shimadzu 1700 UV Visible

spectrophotometer at 210 ndash 215 nm

Viscosity measurement Viscosity of the gel was determined by using Brookfield

viscometer Accurately weighed 100 g of gel was transferred to 100 ml glass beaker Spindle

no S64 was selected and it is immersed into the gel The viscometer was operated at various

rpm until the reading gets stabilized and reading was noted in centipoises It was noted from

the literature that the formulations after gelling should have a viscosity of 50 ndash 50000 cps

In vitro diffusion studies[50]

In-vitrodiffusion study was carried out in a Modified Franz diffusion cell using cellophane

membrane which is heated for 1hr in boiling water The membrane was tied to the donor

compartment and mounted on the reservoir compartment of Franz diffusion cell containing

21 ml of pH 68 phosphate buffer 1 g of Boswellia serrate and Commiphoramukulgel was

placed over the cellophane membrane of donor compartment Whole set was placed on the

magnetic stirrer The study was carried out at 37plusmn 05 ordmC and 100 rpm Samples were

withdrawn from the sampling port of reservoir compartment at regular intervals and

absorbance was measured using Shimadzu 2300 UV visible spectrophotometer at 210 ndash 215

In vivo anti-inflammatory activity[5152535455565758596061 62636465 6667]

Carrageenan induced rat paw edema model volume was used to assess the anti-inflammatory

activity of developed herbal carbopol gel Left hind paws of each Rat were just marked

beyond the tibiotarsal junction so that every time the paw is dipped up to the fixed mark to

ensure constant paw volume The rats (180ndash200g) were randomly divided into 3 groups of 3

rats each Group A normal received normal saline only Edema was induced in the remaining

groups B-CGroup B (toxic control) received carrageenan only without the drug The C

received an application of herbal gel (1g) andor treatment plantar injection of 01 mL of a

1 carageenan wv freshly prepare carageenan in normal saline was given into the left hind

paw of each rat After One hour the gel was applied to the left hind paw of each rat of treated

group Measurements of the paw volume up to the ankle joint were performed before and at

different time intervals (1 2 3 4 5 6 8 10 12h) following the Carrageenan injection using

plethysmometer

Percentage reduction calculated in edema was as follows

Inhibition = Edema (Control) minus Edema (Formulation Treated)

Edema (Control)

Arthritis Activity

Arthritis was induced in rats by subplannter injection of CFA(01 mlrat) in the right hind

paw Rats receiving CFA did not show any sign of acute toxicity Control animals were

injected with 09 saline On day 8 after adjuvant injection these rats were divided in

treatment groups (n = 6 ratsgroup) and injected daily with saline or agmatine 10 20 and 40

mgkg intraperitoneallyupto day 15 The animals were weighed daily The injections were

given daily in between 0900 and 1000 h and animals were subjected to measurement of

arthritis score[68]

as described below Thereafter they were shifted to their cages and the pre-

weighed food pellets were placed inside the cage hopper The food consumed by rats was

quantified by weighing leftover food in the hopper

Arthritis score

Evaluation of arthritis severity was performed by measuring the arthritis index of each

animal which was scored by grading eachpaw from 0 to 4 as described previously[68]

Grading was determined as follows

Rizwan et al World Journal of Pharmaceutical Research

wwwwjprnet Vol 9 Issue 1 2020

Score Sign

0 No erythema or swelling

1 Slight erythema or swelling of one or more digits

2 Swelling of the entire paw

3 Erythema and swelling of the ankle

4 Ankylosis incapacity to bend the ankle

The severity score was the sum of the arthritis scores of the right hind limb maximum upto 4

On day 15 after adjuvant injection blood was withdrawn by retro-orbital method for

biochemical analysis

Paw Volume

The paw volumes of all animals were measured daily till day 15using a plethysmometer (VJ

instrument India) The change in pawvolume was measured as the difference between the

final and initial paw volumes

Stability studies[6970]

4 SUMMARY AND CONCLUSION

Boswellia serrata and Commiphora mukul is an anti-inflammatory and anti-arthritic drugs

used in the treatment of joint pain inflammation and arthritis The purpose of the topical and

dermatological dosage form is to conveniently deliver drug molecules across localized area of

skin Sustained release becomes important to supply the skin with a drug over a prolonged

period of time hence a dermatological delivery system such as gel was considered to be

formulated Beside this gel form may reduce the frequency of dosing intervals and may

improve patient compliance The preliminary phytochemical screening of the extract was

done in view to know the various classes of chemical constituents i e secondary metabolites

From the results of the phytochemical screening of the extracts it was observed that the

fractional product of Commiphora mukul resin contained triterpenoids and sterols

Development of gel was done by using carbapol 934 which was analyzed with a smooth and

homogeneous appearance It was easily spreadable with an acceptable mechanical property

The observation of pH revealed that all the formulations were very near to skin pH make it

suitable for application on skin The results obtained from present work indicated that the

entire drug was uniformly distributed and there was no precipitation in formulation For the

incorporation of drugs five formulae for gel were tried During comparison of these

formulae it was observed that formula 3 showed the smooth texture optimum pH and good

spreadability Hence formula 3 was taken for further studies In vitro drug release of

Boswellic acid and Guggulsterones from gel was performed to study the release behavior of

drug from formulation From the observed results it was concluded that there is increase in

the drug release with respect to time From a patient compliance point of view spreadability

is a important for topical drug delivery system The gel was found to exhibit good percentage

spread by weight that would assure the skin application Anti-Inflammatory Anti-Arthritic

study and Arthritis scoring of the prepared gel formulation evident the Anti-Arthritic activity

of the prepared herbal gel formulation Temperature stability study was performed to evaluate

the separation as well as precipitation of the drug in the excipients mixture It was observed

that the formulation was stable at different temperatures (room temperature cool

temperature elevated temperature and at 75 RH) for 60 days

In the present work the attempt was made to formulate and evaluate a gel for anti-arthritic

activity using extracts of Boswellia serrata and Commiphora mukul The results showed that

the content of Gel components had significant effect on their physical rheological and in

vitro drug release characteristics

1 INTRODUCTION

Rheumatoid arthritis (RA) is a chronic multisystem disease of unknown cause Though the

most prominent manifestation of RA is inflammatory arthritis of the peripheral joints usually

with a symmetrical distribution its systemic manifestations include haematologic

pulmonary neurological and cardiovascular abnormalities RA is a common disease having

peak incidence in 3rd to 4th decades of life with 3-5 times higher preponderance in females

Approximately 20 of patients develop rheumatoid nodules located over the extensor

surfaces of the elbows and fingers About 80 of cases are seropositive for rheumatoid factor

(RF) However RF titres are elevated in certain unrelated diseases too such as in viral

hepatitis cirrhosis sarcoidosis and leprosy Advanced cases show characteristic radiologic

abnormalities such as narrowing of joint space and ulnar deviation of the fingers and radial

deviation of the wrist

Etiopathogenesis Present concept on etiology and pathogenesis proposes that RA occurs in

an immunogenetically predisposed individual to the effect of microbial agents acting as

trigger antigen The role of super antigens which are produced by several microorganisms

with capacity to bind to HLADR molecules (MHC-II region) has also emerged I

Immunologic derangements II Trigger events

The proposed events in immunopathogenesis of RA are

In response to antigenic exposure (eg infectious agent) in a genetically predisposed

individual (HLA-DR) CD4+ T cells are activated

These cells elaborate cytokines the important ones being tumour necrosis factor (TNF)

interferon (IF) interleukin (IL)-1 and IL-6

These cytokines activate endothelial cells B lymphocytes and macrophages

Activation of B-cells releases IgM antibody against IgG (ie anti-IgG) this molecule is

termed rheumatoid factor (RF)

IgG and IgM immune complexes trigger inflammatory damage to the synovium small

blood vessels and collagen

Activated endothelial cells express adhesion molecules which stimulate collection of

inflammatory cells

Activation of macrophages releases more cytokines which cause damage to joint tissues

and vascularisation of cartilage termed pannus formation

Rizwan et al World Journal of Pharmaceutical Research

wwwwjprnet Vol 9 Issue 1 2020

1184

Eventually damage and destruction of bone and cartilage are followed by fibrosis and

ankylosis producing joint deformities

Fig 11 Pathogenesis of RA

Morphologic Features The predominant pathologic lesions are found in the joints and

tendons and less often extra-articular lesions are encountered

Articular Lesions RA involves first the small joints of hands and feet and then

symmetrically affects the joints of wrists elbows ankles and knees The proximal

interphalangeal and metacarpophalangeal joints are affected most severely Frequently

cervical spine is involved but lumbar spine is spared

Rizwan et al World Journal of Pharmaceutical Research

wwwwjprnet Vol 9 Issue 1 2020

1185

Histologically the characteristic feature is diffuse proliferative synovitis with formation of

pannus The microscopic changes are as under

1 Numerous folds of large villi of synovium

2 Marked thickening of the synovial membrane due to oedema congestion and

multilayering of synoviocytes

3 Intense inflammatory cell infiltrate in the synovial membrane with predominance of

lymphocytes plasma cells and some macrophages at places forming lymphoid follicles

Fig 12 The characteristic histologic features are villous hypertrophy of the synovium

and marked mononuclear inflammatory cell infiltrate in synovial membrane with

formation of lymphoid follicles at places

4 Foci of fibrinoid necrosis and fibrin deposition The pannus progressively destroys the

underlying cartilage and subchondral bone This invasion of pannus results in

demineralisation and cystic resorption of underlying bone Later fibrous adhesions or even

bony ankylosis may unite the two opposing joint surfaces In addition persistent

inflammation causes weakening and even rupture of the tendons

Extra-Articular Lesions Nonspecific inflammatory changes are seen in the blood vessels

(acute vasculitis) lungs pleura pericardium myocardium lymph nodes peripheral nerves

and eyes But one of the characteristic extra-articular manifestations of RA is occurrence of

rheumatoid nodules in the skin Rheumatoid nodules are particularly found in the

subcutaneous tissue over pressure points such as the elbows occiput and sacrum The centre

of these nodules consists of an area of fibrinoid necrosis and cellular debris surrounded by

several layers of palisading large epithelioid cells and peripherally there are numerous

Rizwan et al World Journal of Pharmaceutical Research

wwwwjprnet Vol 9 Issue 1 2020

1186

lymphocytes plasma cells and macrophages Similar nodules may be found in the lung

parenchyma pleura heart valves myocardium and other internal organs

There are a few variant forms of RA

1 Juvenile RA found in adolescent patients less than 16 years of age is characterised by

acute onset of fever and predominant involvement of knees and ankles Pathologic changes

are similar but RF is rarely present

2 Feltyrsquos syndrome consists of polyarticular RA associated with splenomegaly and

hypersplenism and consequent haematologic derangements

3 Ankylosing spondylitis or rheumatoid spondylitis is rheumatoid involvement of the

spine particularly sacroiliac joints in young male patients The condition has a strong HLA-

B27 association and may have associated inflammatory diseases such as inflammatory bowel

disease anterior uveitis and Reiterrsquos syndrome

Present Therapy

The goal of rheumatoid arthritis treatment now aims toward achieving the lowest possible

level of arthritis disease activity and remission if possible minimizing joint damage and

enhancing physical function and quality of life The optimal treatment of RA requires a

comprehensive program that combines medical social and emotional support for the patient

It is essential that the patient and the patientrsquos family be educated about the nature and course

of the disease Treatment options include medications reduction of joint stress physical and

occupational therapy and surgical intervention[34]

Proposed Therapy

Herbal medicine provides another approach for treatment of RA and currently a number of

medicinal plants are under scientific evaluation to develop a novel drug There is a dire need

to investigate the complete therapeutic potential and adverse effects if any of these herbals

for providing newer and safer treatment options with minimum side effects

The proposed therapy represents the combination of the following two herbal medicines for

treatment of rheumatoid arthritis in gel form

Commiphora mukul (Guggul)

Boswellia serrata

Skin as a drug delivery target[22 23]

Human skin is essentially composed of two major layers an outer unvascularized epithelial

layer (the epidermis) which contains a rich supply of capillaries sweat glands nerves

sebaceous glands and hair follicles that are supported by connective tissue

Epidermis

It is the outermost multilayer of the skin Its thickness varies depending on number of cells it

contains and its position on the body The multilayered epidermis varies in thickness ranging

from about 08 mm on the palms and soles to 006 mm on the eyelids The different layers of

the epidermis represent the different stages of differentiation of stem cells migrating towards

the surface

Rizwan et al World Journal of Pharmaceutical Research

wwwwjprnet Vol 9 Issue 1 2020

1188

Fig 13 Component of the Epidermis and Dermis of Human Skin

Moving downwards the epidermis is made up of five layers

Stratum corneum (horney layer)

Stratum granulosum (granular layer)

Stratum Malphigion (spin sumpigment layer)

Stratum granulosum (basal layer)

Stratum lucidum

The superficial layer of epidermis and also the final stage of differentiation the stratum

corneumis formed from several layer of dead cells embedded in the lipid matrix It is almost

impermeable and is important in controlling the percutaneous absorption of drugs and other

chemicals

Dermis

The dermis (corneum) 3-5 mm thick consist of matrix of connective tissue woven from

fibrous protein (collagen elastin and reticulin) that is embedded in an amorphous ground of

substances called as mucopolysaccharides nerves blood vessels and lymphaticrsquos traverse the

matrix and appendages pierce it It needs an efficient blood supply to convey nutrients

remove waste products regulate temperature and pressure mobilize skin force and contribute

to skin colour

Rizwan et al World Journal of Pharmaceutical Research

wwwwjprnet Vol 9 Issue 1 2020

1189

Subcutaneous Layer

The subcutaneous layer is beneath the dermis and consists mainly of a type of connective

tissue called Adipose tissue Adipose tissue is more commonly known as fat and helps

cushion the skin and provide protection from cold and temperature fluctuations

Rational approaches to drug delivery in the skin

There are two main ways to attack the problem of formulating a successful topical dosage

form

Directing drugs to the viable skin tissue without using oral systemic or other routes of

therapy

The other approaches use skin delivery for systemic treatment For example transdermal

therapeutic system provides systemic therapy for conditions such as motion sickness and

pain

Gels[13]

Topical gel formulations are of increasing interest in the dermatology industry Gel

formulations are typically transparent or translucent water-based semisolids with good

spreading properties and pleasing aesthetic characteristics

Delivery of drugs to the skin is an effective and targeted therapy for local dermatological

disorders This route of drug delivery has gained popularity because it avoids first pass

effects gastrointestinal irritation and metabolic degradation associated with oral

administration[5]

Due to the first past effect only 25-45 of the orally administered dose

reaches the blood circulation In order to bypass these disadvantages the gel formulations

have been proposed as topical application[6]

Topical gel formulations provide a suitable

delivery system for drugs because they are less greasy and can be easily removed from

the skin Percutaneous absorption of drugs from topical formulations involves the release

of the drug from the formulation and permeation through skin to reach the target tissue

The release of the drug from topical preparations depends on the physicochemical

properties of the vehicle and the drug employed In order to enhance drug release and skin

permeation methods such as the selection of a suitable vehicle co-administration of a

chemical enhancer[7]

have been studied Gel base formulation makes the drug molecules

more easily removable from the system than cream and ointment[89]

Gels for

dermatological use have several favorable properties such as being thixotropic

Rizwan et al World Journal of Pharmaceutical Research

wwwwjprnet Vol 9 Issue 1 2020

1190

greaseless easily spreadable easily removable emollient non-staining compatible with

several excipients and water-soluble or miscible[10]

Guggul and Boswellic acid when presented in the form of topical gel can reduce local

inflammations and arthritis Hence for local inflammation or pain in the body the topical

application of Guggul and Boswellic acid may be useful which also avoids the side

effects associated with the oral therapy Hence a topical gel containing Guggul and

Boswellic acid was prepared[11]

It is established that gel formulations are superior topical

formulation over any other topical formulations because these system have better

application property in comparison to creams and ointments[12]

In the present study the product which was selected is herbal gel The term gel oriented

during the late 1800rsquos as chemists attempted to classify semisolid substances according to

their molecule compositions At that time analytical method needed to determines

chemical structures were lacking Gels and jellies are composed of small amount of solid

dispersed in relatively large amount liquid yet they possess more solid like than liquid

like character In general gels and jellies are rigid enough to maintain their shapes under

a small applied stress

The United States Pharmacopoeia (USP) defines gels as semisolid being either

suspensions of small inorganic particles or large organic molecules interpenetrated with

liquid[14]

It is the interaction between units of the colloidal phase inorganic or organic

that set up the structural viscosity immobilizing liquid the continuous phase[15]

Thus gel

exhibit characteristics intermediate to those of liquid and solids[16]

Classification of gels

Gels are classified into different types based on the characteristics they possess[17]

1 Based on the nature of colloidal phase

a Inorganic gel - Examples Bentonite magma

b Organogel - Examples Polymer gel

These are further subdivided into different sub category according to chemicals nature of

dispersed organic molecules

Natural gums - Example Acacia Carrageenan Xanthan gum etc

Cellulosic derivatives - Examples Sodium carboxymethyl cellulose Hydroxyl ethyl

cellulose Hydroxyl propyl cellulose

Polyethylene and its co-polymer

Synthetic block copolymer eg Poloxamers

2 Based on the Nature of Solvent

The gels are prepared with the help of solvent which act as the continuous phase

b Organogels (Water in oil gels)

c Oleogels

Commiphora mukul is a known anti-inflammatory agent used by Ayurveda physicians

worldwide The analgesic and anti-inflammatory action is almost immediate Guggul is also

used in weight loss formulae and is effective in reducing weight thus helping osteoarthritis

patients directly and indirectly It also reduces blood cholesterol levels Guggulsterone is a

plant chemical that has traditionally been used to treat osteoarthritis It may have anti-

inflammatory effects Part used- Exudate from bark or stem (Resins) Tribal people use the

twig of Guggul as a toothbrush because of its medicinal value Guggul is used to increase

metabolic rate in the ladies Because of anti-inflammatory nature Guggul is used to burn fat

in human bodies It increases bodyrsquos metabolic rate and reduces body fat Hence it is used

for weight loss It helps in functioning of the thyroid It has been proved of reducing breast

cancer It is used against heart diseases hence reduces stroke

Guggul has an excellent effect against rheumatism since centuries Guggul is effective

against painful menstruation It is also used in the treatment of leucorrhoea

Boswellia serrata have been traditionally used in folk medicine for centuries to treat various

chronic inflammatory diseases Part used-Extruded from stem (Resins) The resinous part

of Boswellia serrata possesses monoterpenes diterpenes triterpenes tetracyclic triterpenic

acids and four major pentacyclic triterpenic acids ie β-boswellic acid acetyl-β-boswellic

acid 11-keto-β-boswellic acid and acetyl-11-keto-β-boswellic acid responsible for inhibition

of pro-inflammatory enzymes Out of these four boswellic acids acetyl-11-keto-β-boswellic

acid is the most potent inhibitor of 5-lipoxygenase an enzyme responsible for inflammation

Preliminary phytochemical screening of petroleum ether extract of resin of commiphora

mukul[41]

The plants may be considered as a biosynthetic laboratory for a multitude of compounds like

alkaloids triterpenoids glycosides volatile oils tannins saponins sugars etc that exert

physiological effects These compounds are responsible for therapeutic effects usually the

secondary metabolites The petroleum extracts of Commiphora mukul was subjected to

preliminary phytochemical screening for the detection of various plant constituents The

different phytochemical test are as follows

Tests for sterols alkaloids saponins tannins flavonoids proteins amino acids sugars

Thin layer chromatography study[42 43]

Active extracts those having promising antimicrobial and antifungal activitywere subjected to

thin layer chromatography to find out the number of compounds present in them The details

of the procedure were as follows

A Preparation of the plates

The adsorbent used for thin layer chromatography was silica gel G About 25 g of silica gel G

was taken in a glass mortar and about 35 ml of distilled water was added to it This mixture

was then allowed to swell for 15 minutes The mixture was stirred with glass rod until it

becomes homogeneous Then an additional 15 ml of distilled water was added to it with

stirring The suspension was then transferred to a 150 ml flask fitted with a plastic stopper

and was shaken vigorously for about 2 minutes This suspension was then spreaded

immediately on thin layer chromatographic plates with the help of a thin layer

chromatography (TLC) applicator (SUPERFIT) of Continental Instruments Bombay was

used

B Drying and storage of plates

The freshly coated plates were then air dried until the transparency of the layer had

disappeared The plates were then stacked in a drying rack and were activated in an oven for

30 minutes at 110C The activated plates were then kept ina dessicator till required for

further use

C Application of the sample

For applying test samples on TLC plates glass capillaries were used The spots were applied

with the help of a fine capillary keeping a minimum distance of 1 cm between the two

adjacent spots The spots of the samples were marked on the top of the plate to know their

identity

D Chromatographic chamber conditions of saturation and the development of TLC

plates

Chromatographic rectangular glass chamber (165 x 295 cm) was used in the experiments

To avoid insufficient chamber saturation and the undesirable edge effect a smooth sheet of

filter paper approximately of 15 x 40 cm size was placed in the chromatographic chamber in

a U shape and was allowed to be soaked in the developing solvent After being thus

moistened the paper was then pressed against the walls of the chamber so that it adhered to

the walls The chamber was allowed to saturate for 24 hours before use The experiments

were carried out at room temperature in diffused daylight

E Developing solvent system

A number of developing solvent systems were tried for each residue but the satisfactory

resolution was obtained in the solvent systems mentioned in table TLC results obtained in

these systems are as shown in Table 6

F Spraying equipment

Compressed air sprayer with a fine nozzle was used to detect the different constituents

present on TLC plates Air compressor was attached to a glass sprayer The sprayer was filled

with about 50 ml of the detection reagent and then used After each spray the sprayer was

washed separately with water chromic acid and distilled water and then with acetone

G Detection of The Spots

Spots were detected using UV light (UV Chamber) and spraying (50) H2SO4

The Spreadability of the formulation was determined by an apparatus suggested by muttimer

et al which was suitably modified in the laboratory and used for the study It consists of a

wooden block which was provided by a pulley at one end A rectangular ground glass plate

was fixed on this block An excess of gel (about 1 g) under the study was placed on this

ground plate The gel was then sandwiched between this plate and another glass plate having

the dimension of fixed ground plate and provided with the hook A 1 kg weight was placed

on the top of two plates for 5 minutes to expel air and to provide a uniform film of the gel

between the plates Excess of gel was scrapped off from the edges The top plate was then

subjected to pull of 10g with the help of string attached to the hook and the time (in second)

required by the top plate to cover a distance of 5 cm was noted

Carrageenan induced rat paw edema model volume was used to assess the anti-inflammatory

activity of developed herbal carbopol gel Left hind paws of each Rat were just marked

beyond the tibiotarsal junction so that every time the paw is dipped up to the fixed mark to

ensure constant paw volume The rats (180ndash200g) were randomly divided into 3 groups of 3

rats each Group A normal received normal saline only Edema was induced in the remaining

groups B-CGroup B (toxic control) received carrageenan only without the drug The C

received an application of herbal gel (1g) andor treatment plantar injection of 01 mL of a

1 carageenan wv freshly prepare carageenan in normal saline was given into the left hind

paw of each rat After One hour the gel was applied to the left hind paw of each rat of treated

group Measurements of the paw volume up to the ankle joint were performed before and at

different time intervals (1 2 3 4 5 6 8 10 12h) following the Carrageenan injection using

plethysmometer

Percentage reduction calculated in edema was as follows

Arthritis Activity

Arthritis was induced in rats by subplannter injection of CFA(01 mlrat) in the right hind

paw Rats receiving CFA did not show any sign of acute toxicity Control animals were

injected with 09 saline On day 8 after adjuvant injection these rats were divided in

treatment groups (n = 6 ratsgroup) and injected daily with saline or agmatine 10 20 and 40

mgkg intraperitoneallyupto day 15 The animals were weighed daily The injections were

given daily in between 0900 and 1000 h and animals were subjected to measurement of

arthritis score[68]

as described below Thereafter they were shifted to their cages and the pre-

weighed food pellets were placed inside the cage hopper The food consumed by rats was

quantified by weighing leftover food in the hopper

Arthritis score

Evaluation of arthritis severity was performed by measuring the arthritis index of each

animal which was scored by grading eachpaw from 0 to 4 as described previously[68]

Grading was determined as follows

4 SUMMARY AND CONCLUSION

Boswellia serrata and Commiphora mukul is an anti-inflammatory and anti-arthritic drugs

used in the treatment of joint pain inflammation and arthritis The purpose of the topical and

dermatological dosage form is to conveniently deliver drug molecules across localized area of

skin Sustained release becomes important to supply the skin with a drug over a prolonged

period of time hence a dermatological delivery system such as gel was considered to be

formulated Beside this gel form may reduce the frequency of dosing intervals and may

improve patient compliance The preliminary phytochemical screening of the extract was

done in view to know the various classes of chemical constituents i e secondary metabolites

From the results of the phytochemical screening of the extracts it was observed that the

fractional product of Commiphora mukul resin contained triterpenoids and sterols

Development of gel was done by using carbapol 934 which was analyzed with a smooth and

homogeneous appearance It was easily spreadable with an acceptable mechanical property

The observation of pH revealed that all the formulations were very near to skin pH make it

suitable for application on skin The results obtained from present work indicated that the

entire drug was uniformly distributed and there was no precipitation in formulation For the

incorporation of drugs five formulae for gel were tried During comparison of these

formulae it was observed that formula 3 showed the smooth texture optimum pH and good

spreadability Hence formula 3 was taken for further studies In vitro drug release of

Boswellic acid and Guggulsterones from gel was performed to study the release behavior of

drug from formulation From the observed results it was concluded that there is increase in

the drug release with respect to time From a patient compliance point of view spreadability

is a important for topical drug delivery system The gel was found to exhibit good percentage

spread by weight that would assure the skin application Anti-Inflammatory Anti-Arthritic

study and Arthritis scoring of the prepared gel formulation evident the Anti-Arthritic activity

of the prepared herbal gel formulation Temperature stability study was performed to evaluate

the separation as well as precipitation of the drug in the excipients mixture It was observed

that the formulation was stable at different temperatures (room temperature cool

temperature elevated temperature and at 75 RH) for 60 days

In the present work the attempt was made to formulate and evaluate a gel for anti-arthritic

activity using extracts of Boswellia serrata and Commiphora mukul The results showed that

the content of Gel components had significant effect on their physical rheological and in

vitro drug release characteristics

Eventually damage and destruction of bone and cartilage are followed by fibrosis and

ankylosis producing joint deformities

Fig 11 Pathogenesis of RA

Morphologic Features The predominant pathologic lesions are found in the joints and

tendons and less often extra-articular lesions are encountered

Articular Lesions RA involves first the small joints of hands and feet and then

symmetrically affects the joints of wrists elbows ankles and knees The proximal

interphalangeal and metacarpophalangeal joints are affected most severely Frequently

cervical spine is involved but lumbar spine is spared

Rizwan et al World Journal of Pharmaceutical Research

wwwwjprnet Vol 9 Issue 1 2020

1185

Histologically the characteristic feature is diffuse proliferative synovitis with formation of

pannus The microscopic changes are as under

1 Numerous folds of large villi of synovium

2 Marked thickening of the synovial membrane due to oedema congestion and

multilayering of synoviocytes

3 Intense inflammatory cell infiltrate in the synovial membrane with predominance of

lymphocytes plasma cells and some macrophages at places forming lymphoid follicles

Fig 12 The characteristic histologic features are villous hypertrophy of the synovium

and marked mononuclear inflammatory cell infiltrate in synovial membrane with

formation of lymphoid follicles at places

4 Foci of fibrinoid necrosis and fibrin deposition The pannus progressively destroys the

underlying cartilage and subchondral bone This invasion of pannus results in

demineralisation and cystic resorption of underlying bone Later fibrous adhesions or even

bony ankylosis may unite the two opposing joint surfaces In addition persistent

inflammation causes weakening and even rupture of the tendons

Extra-Articular Lesions Nonspecific inflammatory changes are seen in the blood vessels

(acute vasculitis) lungs pleura pericardium myocardium lymph nodes peripheral nerves

and eyes But one of the characteristic extra-articular manifestations of RA is occurrence of

rheumatoid nodules in the skin Rheumatoid nodules are particularly found in the

subcutaneous tissue over pressure points such as the elbows occiput and sacrum The centre

of these nodules consists of an area of fibrinoid necrosis and cellular debris surrounded by

several layers of palisading large epithelioid cells and peripherally there are numerous

Rizwan et al World Journal of Pharmaceutical Research

wwwwjprnet Vol 9 Issue 1 2020

1186

lymphocytes plasma cells and macrophages Similar nodules may be found in the lung

parenchyma pleura heart valves myocardium and other internal organs

There are a few variant forms of RA

1 Juvenile RA found in adolescent patients less than 16 years of age is characterised by

acute onset of fever and predominant involvement of knees and ankles Pathologic changes

are similar but RF is rarely present

2 Feltyrsquos syndrome consists of polyarticular RA associated with splenomegaly and

hypersplenism and consequent haematologic derangements

3 Ankylosing spondylitis or rheumatoid spondylitis is rheumatoid involvement of the

spine particularly sacroiliac joints in young male patients The condition has a strong HLA-

B27 association and may have associated inflammatory diseases such as inflammatory bowel

disease anterior uveitis and Reiterrsquos syndrome

Present Therapy

The goal of rheumatoid arthritis treatment now aims toward achieving the lowest possible

level of arthritis disease activity and remission if possible minimizing joint damage and

enhancing physical function and quality of life The optimal treatment of RA requires a

comprehensive program that combines medical social and emotional support for the patient

It is essential that the patient and the patientrsquos family be educated about the nature and course

of the disease Treatment options include medications reduction of joint stress physical and

occupational therapy and surgical intervention[34]

Proposed Therapy

Herbal medicine provides another approach for treatment of RA and currently a number of

medicinal plants are under scientific evaluation to develop a novel drug There is a dire need

to investigate the complete therapeutic potential and adverse effects if any of these herbals

for providing newer and safer treatment options with minimum side effects

The proposed therapy represents the combination of the following two herbal medicines for

treatment of rheumatoid arthritis in gel form

Commiphora mukul (Guggul)

Boswellia serrata

Skin as a drug delivery target[22 23]

Human skin is essentially composed of two major layers an outer unvascularized epithelial

layer (the epidermis) which contains a rich supply of capillaries sweat glands nerves

sebaceous glands and hair follicles that are supported by connective tissue

Epidermis

It is the outermost multilayer of the skin Its thickness varies depending on number of cells it

contains and its position on the body The multilayered epidermis varies in thickness ranging

from about 08 mm on the palms and soles to 006 mm on the eyelids The different layers of

the epidermis represent the different stages of differentiation of stem cells migrating towards

the surface

Rizwan et al World Journal of Pharmaceutical Research

wwwwjprnet Vol 9 Issue 1 2020

1188

Fig 13 Component of the Epidermis and Dermis of Human Skin

Moving downwards the epidermis is made up of five layers

Stratum corneum (horney layer)

Stratum granulosum (granular layer)

Stratum Malphigion (spin sumpigment layer)

Stratum granulosum (basal layer)

Stratum lucidum

The superficial layer of epidermis and also the final stage of differentiation the stratum

corneumis formed from several layer of dead cells embedded in the lipid matrix It is almost

impermeable and is important in controlling the percutaneous absorption of drugs and other

chemicals

Dermis

The dermis (corneum) 3-5 mm thick consist of matrix of connective tissue woven from

fibrous protein (collagen elastin and reticulin) that is embedded in an amorphous ground of

substances called as mucopolysaccharides nerves blood vessels and lymphaticrsquos traverse the

matrix and appendages pierce it It needs an efficient blood supply to convey nutrients

remove waste products regulate temperature and pressure mobilize skin force and contribute

to skin colour

Rizwan et al World Journal of Pharmaceutical Research

wwwwjprnet Vol 9 Issue 1 2020

1189

Subcutaneous Layer

The subcutaneous layer is beneath the dermis and consists mainly of a type of connective

tissue called Adipose tissue Adipose tissue is more commonly known as fat and helps

cushion the skin and provide protection from cold and temperature fluctuations

Rational approaches to drug delivery in the skin

There are two main ways to attack the problem of formulating a successful topical dosage

form

Directing drugs to the viable skin tissue without using oral systemic or other routes of

therapy

The other approaches use skin delivery for systemic treatment For example transdermal

therapeutic system provides systemic therapy for conditions such as motion sickness and

pain

Gels[13]

Topical gel formulations are of increasing interest in the dermatology industry Gel

formulations are typically transparent or translucent water-based semisolids with good

spreading properties and pleasing aesthetic characteristics

Delivery of drugs to the skin is an effective and targeted therapy for local dermatological

disorders This route of drug delivery has gained popularity because it avoids first pass

effects gastrointestinal irritation and metabolic degradation associated with oral

administration[5]

Due to the first past effect only 25-45 of the orally administered dose

reaches the blood circulation In order to bypass these disadvantages the gel formulations

have been proposed as topical application[6]

Topical gel formulations provide a suitable

delivery system for drugs because they are less greasy and can be easily removed from

the skin Percutaneous absorption of drugs from topical formulations involves the release

of the drug from the formulation and permeation through skin to reach the target tissue

The release of the drug from topical preparations depends on the physicochemical

properties of the vehicle and the drug employed In order to enhance drug release and skin

permeation methods such as the selection of a suitable vehicle co-administration of a

chemical enhancer[7]

have been studied Gel base formulation makes the drug molecules

more easily removable from the system than cream and ointment[89]

Gels for

dermatological use have several favorable properties such as being thixotropic

Rizwan et al World Journal of Pharmaceutical Research

wwwwjprnet Vol 9 Issue 1 2020

1190

greaseless easily spreadable easily removable emollient non-staining compatible with

several excipients and water-soluble or miscible[10]

Guggul and Boswellic acid when presented in the form of topical gel can reduce local

inflammations and arthritis Hence for local inflammation or pain in the body the topical

application of Guggul and Boswellic acid may be useful which also avoids the side

effects associated with the oral therapy Hence a topical gel containing Guggul and

Boswellic acid was prepared[11]

It is established that gel formulations are superior topical

formulation over any other topical formulations because these system have better

application property in comparison to creams and ointments[12]

In the present study the product which was selected is herbal gel The term gel oriented

during the late 1800rsquos as chemists attempted to classify semisolid substances according to

their molecule compositions At that time analytical method needed to determines

chemical structures were lacking Gels and jellies are composed of small amount of solid

dispersed in relatively large amount liquid yet they possess more solid like than liquid

like character In general gels and jellies are rigid enough to maintain their shapes under

a small applied stress

The United States Pharmacopoeia (USP) defines gels as semisolid being either

suspensions of small inorganic particles or large organic molecules interpenetrated with

liquid[14]

It is the interaction between units of the colloidal phase inorganic or organic

that set up the structural viscosity immobilizing liquid the continuous phase[15]

Thus gel

exhibit characteristics intermediate to those of liquid and solids[16]

Classification of gels

Gels are classified into different types based on the characteristics they possess[17]

1 Based on the nature of colloidal phase

a Inorganic gel - Examples Bentonite magma

b Organogel - Examples Polymer gel

These are further subdivided into different sub category according to chemicals nature of

dispersed organic molecules

Natural gums - Example Acacia Carrageenan Xanthan gum etc

Cellulosic derivatives - Examples Sodium carboxymethyl cellulose Hydroxyl ethyl

cellulose Hydroxyl propyl cellulose

Polyethylene and its co-polymer

mass was exhausted with hot water the residue was collected on an ashless filter paper the

residue and the filter paper was incinerated until the ash was white or nearly so the filtrate

was added evaporated to dryness and ignited at a temperature not exceeding 450ordmC The

percentage of ash was calculated with reference to their air dried drug

Moisture content Water content is determined by removing the moisture and then by

measuring weight loss

Successive solvent extraction of resin[40]

The resin Commiphora mukul was taken and loaded in soxhlet extractor and extracted with

ethyl acetate about five times the weight of gum The temp is kept at 65-70degC The extracted

fluid is taken for solvent recovery The oleoresin (thick paste) obtained after solvent removal

was purified for enrichment of guggulsterones by solvent frication method 2 g sample of

guggul extract was taken in 250 mL round bottom flask 35 mL of 05 M alcoholic KOH was

added and reflux for 90 min on a water bath The content of flask was transferred to a

separator rinsed the flask with 50 mL lukewarm water Extracted while the liquid was warm

by shaking vigorously with three successive quantities of 50 mL petroleum ether (60-80deg)

Then combine the petroleum ether layers and wash with 20 mL water Evaporated the

petroleum ether and weighed the residue

Preliminary phytochemical screening of petroleum ether extract of resin of commiphora

mukul[41]

The plants may be considered as a biosynthetic laboratory for a multitude of compounds like

alkaloids triterpenoids glycosides volatile oils tannins saponins sugars etc that exert

physiological effects These compounds are responsible for therapeutic effects usually the

secondary metabolites The petroleum extracts of Commiphora mukul was subjected to

preliminary phytochemical screening for the detection of various plant constituents The

different phytochemical test are as follows

Tests for sterols alkaloids saponins tannins flavonoids proteins amino acids sugars

Thin layer chromatography study[42 43]

Active extracts those having promising antimicrobial and antifungal activitywere subjected to

thin layer chromatography to find out the number of compounds present in them The details

of the procedure were as follows

A Preparation of the plates

The adsorbent used for thin layer chromatography was silica gel G About 25 g of silica gel G

was taken in a glass mortar and about 35 ml of distilled water was added to it This mixture

was then allowed to swell for 15 minutes The mixture was stirred with glass rod until it

becomes homogeneous Then an additional 15 ml of distilled water was added to it with

stirring The suspension was then transferred to a 150 ml flask fitted with a plastic stopper

and was shaken vigorously for about 2 minutes This suspension was then spreaded

immediately on thin layer chromatographic plates with the help of a thin layer

chromatography (TLC) applicator (SUPERFIT) of Continental Instruments Bombay was

used

B Drying and storage of plates

The freshly coated plates were then air dried until the transparency of the layer had

disappeared The plates were then stacked in a drying rack and were activated in an oven for

30 minutes at 110C The activated plates were then kept ina dessicator till required for

further use

C Application of the sample

For applying test samples on TLC plates glass capillaries were used The spots were applied

with the help of a fine capillary keeping a minimum distance of 1 cm between the two

adjacent spots The spots of the samples were marked on the top of the plate to know their

identity

D Chromatographic chamber conditions of saturation and the development of TLC

plates

Chromatographic rectangular glass chamber (165 x 295 cm) was used in the experiments

To avoid insufficient chamber saturation and the undesirable edge effect a smooth sheet of

filter paper approximately of 15 x 40 cm size was placed in the chromatographic chamber in

a U shape and was allowed to be soaked in the developing solvent After being thus

moistened the paper was then pressed against the walls of the chamber so that it adhered to

the walls The chamber was allowed to saturate for 24 hours before use The experiments

were carried out at room temperature in diffused daylight

E Developing solvent system

A number of developing solvent systems were tried for each residue but the satisfactory

resolution was obtained in the solvent systems mentioned in table TLC results obtained in

these systems are as shown in Table 6

F Spraying equipment

Compressed air sprayer with a fine nozzle was used to detect the different constituents

present on TLC plates Air compressor was attached to a glass sprayer The sprayer was filled

with about 50 ml of the detection reagent and then used After each spray the sprayer was

washed separately with water chromic acid and distilled water and then with acetone

G Detection of The Spots

Spots were detected using UV light (UV Chamber) and spraying (50) H2SO4

4 SUMMARY AND CONCLUSION

Boswellia serrata and Commiphora mukul is an anti-inflammatory and anti-arthritic drugs

used in the treatment of joint pain inflammation and arthritis The purpose of the topical and

dermatological dosage form is to conveniently deliver drug molecules across localized area of

skin Sustained release becomes important to supply the skin with a drug over a prolonged

period of time hence a dermatological delivery system such as gel was considered to be

formulated Beside this gel form may reduce the frequency of dosing intervals and may

improve patient compliance The preliminary phytochemical screening of the extract was

done in view to know the various classes of chemical constituents i e secondary metabolites

From the results of the phytochemical screening of the extracts it was observed that the

fractional product of Commiphora mukul resin contained triterpenoids and sterols

Development of gel was done by using carbapol 934 which was analyzed with a smooth and

homogeneous appearance It was easily spreadable with an acceptable mechanical property

The observation of pH revealed that all the formulations were very near to skin pH make it

suitable for application on skin The results obtained from present work indicated that the

entire drug was uniformly distributed and there was no precipitation in formulation For the

incorporation of drugs five formulae for gel were tried During comparison of these

formulae it was observed that formula 3 showed the smooth texture optimum pH and good

spreadability Hence formula 3 was taken for further studies In vitro drug release of

Boswellic acid and Guggulsterones from gel was performed to study the release behavior of

drug from formulation From the observed results it was concluded that there is increase in

the drug release with respect to time From a patient compliance point of view spreadability

is a important for topical drug delivery system The gel was found to exhibit good percentage

spread by weight that would assure the skin application Anti-Inflammatory Anti-Arthritic

study and Arthritis scoring of the prepared gel formulation evident the Anti-Arthritic activity

of the prepared herbal gel formulation Temperature stability study was performed to evaluate

the separation as well as precipitation of the drug in the excipients mixture It was observed

that the formulation was stable at different temperatures (room temperature cool

temperature elevated temperature and at 75 RH) for 60 days

In the present work the attempt was made to formulate and evaluate a gel for anti-arthritic

activity using extracts of Boswellia serrata and Commiphora mukul The results showed that

the content of Gel components had significant effect on their physical rheological and in

vitro drug release characteristics

Histologically the characteristic feature is diffuse proliferative synovitis with formation of

pannus The microscopic changes are as under

1 Numerous folds of large villi of synovium

2 Marked thickening of the synovial membrane due to oedema congestion and

multilayering of synoviocytes

3 Intense inflammatory cell infiltrate in the synovial membrane with predominance of

lymphocytes plasma cells and some macrophages at places forming lymphoid follicles

Fig 12 The characteristic histologic features are villous hypertrophy of the synovium

and marked mononuclear inflammatory cell infiltrate in synovial membrane with

formation of lymphoid follicles at places

4 Foci of fibrinoid necrosis and fibrin deposition The pannus progressively destroys the

underlying cartilage and subchondral bone This invasion of pannus results in

demineralisation and cystic resorption of underlying bone Later fibrous adhesions or even

bony ankylosis may unite the two opposing joint surfaces In addition persistent

inflammation causes weakening and even rupture of the tendons

Extra-Articular Lesions Nonspecific inflammatory changes are seen in the blood vessels

(acute vasculitis) lungs pleura pericardium myocardium lymph nodes peripheral nerves

and eyes But one of the characteristic extra-articular manifestations of RA is occurrence of

rheumatoid nodules in the skin Rheumatoid nodules are particularly found in the

subcutaneous tissue over pressure points such as the elbows occiput and sacrum The centre

of these nodules consists of an area of fibrinoid necrosis and cellular debris surrounded by

several layers of palisading large epithelioid cells and peripherally there are numerous

Rizwan et al World Journal of Pharmaceutical Research

wwwwjprnet Vol 9 Issue 1 2020

1186

lymphocytes plasma cells and macrophages Similar nodules may be found in the lung

parenchyma pleura heart valves myocardium and other internal organs

There are a few variant forms of RA

1 Juvenile RA found in adolescent patients less than 16 years of age is characterised by

acute onset of fever and predominant involvement of knees and ankles Pathologic changes

are similar but RF is rarely present

2 Feltyrsquos syndrome consists of polyarticular RA associated with splenomegaly and

hypersplenism and consequent haematologic derangements

3 Ankylosing spondylitis or rheumatoid spondylitis is rheumatoid involvement of the

spine particularly sacroiliac joints in young male patients The condition has a strong HLA-

B27 association and may have associated inflammatory diseases such as inflammatory bowel

disease anterior uveitis and Reiterrsquos syndrome

Present Therapy

The goal of rheumatoid arthritis treatment now aims toward achieving the lowest possible

level of arthritis disease activity and remission if possible minimizing joint damage and

enhancing physical function and quality of life The optimal treatment of RA requires a

comprehensive program that combines medical social and emotional support for the patient

It is essential that the patient and the patientrsquos family be educated about the nature and course

of the disease Treatment options include medications reduction of joint stress physical and

occupational therapy and surgical intervention[34]

Proposed Therapy

Herbal medicine provides another approach for treatment of RA and currently a number of

medicinal plants are under scientific evaluation to develop a novel drug There is a dire need

to investigate the complete therapeutic potential and adverse effects if any of these herbals

for providing newer and safer treatment options with minimum side effects

The proposed therapy represents the combination of the following two herbal medicines for

treatment of rheumatoid arthritis in gel form

Commiphora mukul (Guggul)

Boswellia serrata

Skin as a drug delivery target[22 23]

Human skin is essentially composed of two major layers an outer unvascularized epithelial

layer (the epidermis) which contains a rich supply of capillaries sweat glands nerves

sebaceous glands and hair follicles that are supported by connective tissue

Epidermis

It is the outermost multilayer of the skin Its thickness varies depending on number of cells it

contains and its position on the body The multilayered epidermis varies in thickness ranging

from about 08 mm on the palms and soles to 006 mm on the eyelids The different layers of

the epidermis represent the different stages of differentiation of stem cells migrating towards

the surface

Fig 13 Component of the Epidermis and Dermis of Human Skin

Moving downwards the epidermis is made up of five layers

Stratum corneum (horney layer)

Stratum granulosum (granular layer)

Stratum Malphigion (spin sumpigment layer)

Stratum granulosum (basal layer)

Stratum lucidum

The superficial layer of epidermis and also the final stage of differentiation the stratum

corneumis formed from several layer of dead cells embedded in the lipid matrix It is almost

impermeable and is important in controlling the percutaneous absorption of drugs and other

chemicals

Dermis

The dermis (corneum) 3-5 mm thick consist of matrix of connective tissue woven from

fibrous protein (collagen elastin and reticulin) that is embedded in an amorphous ground of

substances called as mucopolysaccharides nerves blood vessels and lymphaticrsquos traverse the

matrix and appendages pierce it It needs an efficient blood supply to convey nutrients

remove waste products regulate temperature and pressure mobilize skin force and contribute

to skin colour

Subcutaneous Layer

The subcutaneous layer is beneath the dermis and consists mainly of a type of connective

tissue called Adipose tissue Adipose tissue is more commonly known as fat and helps

cushion the skin and provide protection from cold and temperature fluctuations

Rational approaches to drug delivery in the skin

There are two main ways to attack the problem of formulating a successful topical dosage

form

Directing drugs to the viable skin tissue without using oral systemic or other routes of

therapy

The other approaches use skin delivery for systemic treatment For example transdermal

therapeutic system provides systemic therapy for conditions such as motion sickness and

pain

Gels[13]

Topical gel formulations are of increasing interest in the dermatology industry Gel

formulations are typically transparent or translucent water-based semisolids with good

spreading properties and pleasing aesthetic characteristics

Delivery of drugs to the skin is an effective and targeted therapy for local dermatological

disorders This route of drug delivery has gained popularity because it avoids first pass

effects gastrointestinal irritation and metabolic degradation associated with oral

administration[5]

Due to the first past effect only 25-45 of the orally administered dose

reaches the blood circulation In order to bypass these disadvantages the gel formulations

have been proposed as topical application[6]

Topical gel formulations provide a suitable

delivery system for drugs because they are less greasy and can be easily removed from

the skin Percutaneous absorption of drugs from topical formulations involves the release

of the drug from the formulation and permeation through skin to reach the target tissue

The release of the drug from topical preparations depends on the physicochemical

properties of the vehicle and the drug employed In order to enhance drug release and skin

permeation methods such as the selection of a suitable vehicle co-administration of a

chemical enhancer[7]

have been studied Gel base formulation makes the drug molecules

more easily removable from the system than cream and ointment[89]

Gels for

dermatological use have several favorable properties such as being thixotropic

Rizwan et al World Journal of Pharmaceutical Research

wwwwjprnet Vol 9 Issue 1 2020

1190

greaseless easily spreadable easily removable emollient non-staining compatible with

several excipients and water-soluble or miscible[10]

Guggul and Boswellic acid when presented in the form of topical gel can reduce local

inflammations and arthritis Hence for local inflammation or pain in the body the topical

application of Guggul and Boswellic acid may be useful which also avoids the side

effects associated with the oral therapy Hence a topical gel containing Guggul and

Boswellic acid was prepared[11]

It is established that gel formulations are superior topical

formulation over any other topical formulations because these system have better

application property in comparison to creams and ointments[12]

In the present study the product which was selected is herbal gel The term gel oriented

during the late 1800rsquos as chemists attempted to classify semisolid substances according to

their molecule compositions At that time analytical method needed to determines

chemical structures were lacking Gels and jellies are composed of small amount of solid

dispersed in relatively large amount liquid yet they possess more solid like than liquid

like character In general gels and jellies are rigid enough to maintain their shapes under

a small applied stress

The United States Pharmacopoeia (USP) defines gels as semisolid being either

suspensions of small inorganic particles or large organic molecules interpenetrated with

liquid[14]

It is the interaction between units of the colloidal phase inorganic or organic

that set up the structural viscosity immobilizing liquid the continuous phase[15]

Thus gel

exhibit characteristics intermediate to those of liquid and solids[16]

Classification of gels

Gels are classified into different types based on the characteristics they possess[17]

1 Based on the nature of colloidal phase

a Inorganic gel - Examples Bentonite magma

b Organogel - Examples Polymer gel

These are further subdivided into different sub category according to chemicals nature of

dispersed organic molecules

Natural gums - Example Acacia Carrageenan Xanthan gum etc

Cellulosic derivatives - Examples Sodium carboxymethyl cellulose Hydroxyl ethyl

cellulose Hydroxyl propyl cellulose

Polyethylene and its co-polymer

mass was exhausted with hot water the residue was collected on an ashless filter paper the

residue and the filter paper was incinerated until the ash was white or nearly so the filtrate

was added evaporated to dryness and ignited at a temperature not exceeding 450ordmC The

percentage of ash was calculated with reference to their air dried drug

Moisture content Water content is determined by removing the moisture and then by

measuring weight loss

Successive solvent extraction of resin[40]

The resin Commiphora mukul was taken and loaded in soxhlet extractor and extracted with

ethyl acetate about five times the weight of gum The temp is kept at 65-70degC The extracted

fluid is taken for solvent recovery The oleoresin (thick paste) obtained after solvent removal

was purified for enrichment of guggulsterones by solvent frication method 2 g sample of

guggul extract was taken in 250 mL round bottom flask 35 mL of 05 M alcoholic KOH was

added and reflux for 90 min on a water bath The content of flask was transferred to a

separator rinsed the flask with 50 mL lukewarm water Extracted while the liquid was warm

by shaking vigorously with three successive quantities of 50 mL petroleum ether (60-80deg)

Then combine the petroleum ether layers and wash with 20 mL water Evaporated the

petroleum ether and weighed the residue

Preliminary phytochemical screening of petroleum ether extract of resin of commiphora

mukul[41]

The plants may be considered as a biosynthetic laboratory for a multitude of compounds like

alkaloids triterpenoids glycosides volatile oils tannins saponins sugars etc that exert

physiological effects These compounds are responsible for therapeutic effects usually the

secondary metabolites The petroleum extracts of Commiphora mukul was subjected to

preliminary phytochemical screening for the detection of various plant constituents The

different phytochemical test are as follows

Tests for sterols alkaloids saponins tannins flavonoids proteins amino acids sugars

Thin layer chromatography study[42 43]

Active extracts those having promising antimicrobial and antifungal activitywere subjected to

thin layer chromatography to find out the number of compounds present in them The details

of the procedure were as follows

A Preparation of the plates

The adsorbent used for thin layer chromatography was silica gel G About 25 g of silica gel G

was taken in a glass mortar and about 35 ml of distilled water was added to it This mixture

was then allowed to swell for 15 minutes The mixture was stirred with glass rod until it

becomes homogeneous Then an additional 15 ml of distilled water was added to it with

stirring The suspension was then transferred to a 150 ml flask fitted with a plastic stopper

and was shaken vigorously for about 2 minutes This suspension was then spreaded

immediately on thin layer chromatographic plates with the help of a thin layer

chromatography (TLC) applicator (SUPERFIT) of Continental Instruments Bombay was

used

B Drying and storage of plates

The freshly coated plates were then air dried until the transparency of the layer had

disappeared The plates were then stacked in a drying rack and were activated in an oven for

30 minutes at 110C The activated plates were then kept ina dessicator till required for

further use

C Application of the sample

For applying test samples on TLC plates glass capillaries were used The spots were applied

with the help of a fine capillary keeping a minimum distance of 1 cm between the two

adjacent spots The spots of the samples were marked on the top of the plate to know their

identity

D Chromatographic chamber conditions of saturation and the development of TLC

plates

Chromatographic rectangular glass chamber (165 x 295 cm) was used in the experiments

To avoid insufficient chamber saturation and the undesirable edge effect a smooth sheet of

filter paper approximately of 15 x 40 cm size was placed in the chromatographic chamber in

a U shape and was allowed to be soaked in the developing solvent After being thus

moistened the paper was then pressed against the walls of the chamber so that it adhered to

the walls The chamber was allowed to saturate for 24 hours before use The experiments

were carried out at room temperature in diffused daylight

E Developing solvent system

A number of developing solvent systems were tried for each residue but the satisfactory

resolution was obtained in the solvent systems mentioned in table TLC results obtained in

these systems are as shown in Table 6

F Spraying equipment

Compressed air sprayer with a fine nozzle was used to detect the different constituents

present on TLC plates Air compressor was attached to a glass sprayer The sprayer was filled

with about 50 ml of the detection reagent and then used After each spray the sprayer was

washed separately with water chromic acid and distilled water and then with acetone

G Detection of The Spots

Spots were detected using UV light (UV Chamber) and spraying (50) H2SO4

The Spreadability of the formulation was determined by an apparatus suggested by muttimer

et al which was suitably modified in the laboratory and used for the study It consists of a

wooden block which was provided by a pulley at one end A rectangular ground glass plate

was fixed on this block An excess of gel (about 1 g) under the study was placed on this

ground plate The gel was then sandwiched between this plate and another glass plate having

the dimension of fixed ground plate and provided with the hook A 1 kg weight was placed

on the top of two plates for 5 minutes to expel air and to provide a uniform film of the gel

between the plates Excess of gel was scrapped off from the edges The top plate was then

subjected to pull of 10g with the help of string attached to the hook and the time (in second)

required by the top plate to cover a distance of 5 cm was noted

Carrageenan induced rat paw edema model volume was used to assess the anti-inflammatory

activity of developed herbal carbopol gel Left hind paws of each Rat were just marked

beyond the tibiotarsal junction so that every time the paw is dipped up to the fixed mark to

ensure constant paw volume The rats (180ndash200g) were randomly divided into 3 groups of 3

rats each Group A normal received normal saline only Edema was induced in the remaining

groups B-CGroup B (toxic control) received carrageenan only without the drug The C

received an application of herbal gel (1g) andor treatment plantar injection of 01 mL of a

1 carageenan wv freshly prepare carageenan in normal saline was given into the left hind

paw of each rat After One hour the gel was applied to the left hind paw of each rat of treated

group Measurements of the paw volume up to the ankle joint were performed before and at

different time intervals (1 2 3 4 5 6 8 10 12h) following the Carrageenan injection using

plethysmometer

Percentage reduction calculated in edema was as follows

UV-Visible Spectrophotometric Analysis

a) UV Spectroscopy

The maximum absorption value of extracted drug Commiphora mukul was found at 205 nm

wavelength in phosphate buffer pH 68 Therefore 205 nm was recorded as λmax of the

extracted drug Commiphora mukul The observed λmax value of drug was found to be

complies with the specification of Indian pharmacopoeia Hence the drug was considered to

be pure The UV spectrum of Commiphora mukul is shown in Figure 64

b) Calibration curve of Commiphora mukul in phosphate buffer pH 68

A solution of 100 microgml of Commiphora mukul was scanned in the range of 200 to 400 nm

The drug exhibited the λmax at 205 nm and showed reproducibility

From the standard curve of Commiphora mukul in phosphate buffer pH 68 it was observed

that the Commiphora mukul obeys Beers-Lambertrsquos law in the range 10-50microgml in the

medium as shown in table 65 and figure 67

4 SUMMARY AND CONCLUSION

Boswellia serrata and Commiphora mukul is an anti-inflammatory and anti-arthritic drugs

used in the treatment of joint pain inflammation and arthritis The purpose of the topical and

dermatological dosage form is to conveniently deliver drug molecules across localized area of

skin Sustained release becomes important to supply the skin with a drug over a prolonged

period of time hence a dermatological delivery system such as gel was considered to be

formulated Beside this gel form may reduce the frequency of dosing intervals and may

improve patient compliance The preliminary phytochemical screening of the extract was

done in view to know the various classes of chemical constituents i e secondary metabolites

From the results of the phytochemical screening of the extracts it was observed that the

fractional product of Commiphora mukul resin contained triterpenoids and sterols

Development of gel was done by using carbapol 934 which was analyzed with a smooth and

homogeneous appearance It was easily spreadable with an acceptable mechanical property

The observation of pH revealed that all the formulations were very near to skin pH make it

suitable for application on skin The results obtained from present work indicated that the

entire drug was uniformly distributed and there was no precipitation in formulation For the

incorporation of drugs five formulae for gel were tried During comparison of these

formulae it was observed that formula 3 showed the smooth texture optimum pH and good

spreadability Hence formula 3 was taken for further studies In vitro drug release of

Boswellic acid and Guggulsterones from gel was performed to study the release behavior of

drug from formulation From the observed results it was concluded that there is increase in

the drug release with respect to time From a patient compliance point of view spreadability

is a important for topical drug delivery system The gel was found to exhibit good percentage

spread by weight that would assure the skin application Anti-Inflammatory Anti-Arthritic

study and Arthritis scoring of the prepared gel formulation evident the Anti-Arthritic activity

of the prepared herbal gel formulation Temperature stability study was performed to evaluate

the separation as well as precipitation of the drug in the excipients mixture It was observed

that the formulation was stable at different temperatures (room temperature cool

temperature elevated temperature and at 75 RH) for 60 days

In the present work the attempt was made to formulate and evaluate a gel for anti-arthritic

activity using extracts of Boswellia serrata and Commiphora mukul The results showed that

the content of Gel components had significant effect on their physical rheological and in

vitro drug release characteristics

lymphocytes plasma cells and macrophages Similar nodules may be found in the lung

parenchyma pleura heart valves myocardium and other internal organs

There are a few variant forms of RA

1 Juvenile RA found in adolescent patients less than 16 years of age is characterised by

acute onset of fever and predominant involvement of knees and ankles Pathologic changes

are similar but RF is rarely present

2 Feltyrsquos syndrome consists of polyarticular RA associated with splenomegaly and

hypersplenism and consequent haematologic derangements

3 Ankylosing spondylitis or rheumatoid spondylitis is rheumatoid involvement of the

spine particularly sacroiliac joints in young male patients The condition has a strong HLA-

B27 association and may have associated inflammatory diseases such as inflammatory bowel

disease anterior uveitis and Reiterrsquos syndrome

Present Therapy

The goal of rheumatoid arthritis treatment now aims toward achieving the lowest possible

level of arthritis disease activity and remission if possible minimizing joint damage and

enhancing physical function and quality of life The optimal treatment of RA requires a

comprehensive program that combines medical social and emotional support for the patient

It is essential that the patient and the patientrsquos family be educated about the nature and course

of the disease Treatment options include medications reduction of joint stress physical and

occupational therapy and surgical intervention[34]

Proposed Therapy

Herbal medicine provides another approach for treatment of RA and currently a number of

medicinal plants are under scientific evaluation to develop a novel drug There is a dire need

to investigate the complete therapeutic potential and adverse effects if any of these herbals

for providing newer and safer treatment options with minimum side effects

The proposed therapy represents the combination of the following two herbal medicines for

treatment of rheumatoid arthritis in gel form

Commiphora mukul (Guggul)

Boswellia serrata

Skin as a drug delivery target[22 23]

Human skin is essentially composed of two major layers an outer unvascularized epithelial

layer (the epidermis) which contains a rich supply of capillaries sweat glands nerves

sebaceous glands and hair follicles that are supported by connective tissue

Epidermis

It is the outermost multilayer of the skin Its thickness varies depending on number of cells it

contains and its position on the body The multilayered epidermis varies in thickness ranging

from about 08 mm on the palms and soles to 006 mm on the eyelids The different layers of

the epidermis represent the different stages of differentiation of stem cells migrating towards

the surface

Rizwan et al World Journal of Pharmaceutical Research

wwwwjprnet Vol 9 Issue 1 2020

1188

Fig 13 Component of the Epidermis and Dermis of Human Skin

Moving downwards the epidermis is made up of five layers

Stratum corneum (horney layer)

Stratum granulosum (granular layer)

Stratum Malphigion (spin sumpigment layer)

Stratum granulosum (basal layer)

Stratum lucidum

The superficial layer of epidermis and also the final stage of differentiation the stratum

corneumis formed from several layer of dead cells embedded in the lipid matrix It is almost

impermeable and is important in controlling the percutaneous absorption of drugs and other

chemicals

Dermis

The dermis (corneum) 3-5 mm thick consist of matrix of connective tissue woven from

fibrous protein (collagen elastin and reticulin) that is embedded in an amorphous ground of

substances called as mucopolysaccharides nerves blood vessels and lymphaticrsquos traverse the

matrix and appendages pierce it It needs an efficient blood supply to convey nutrients

remove waste products regulate temperature and pressure mobilize skin force and contribute

to skin colour

Rizwan et al World Journal of Pharmaceutical Research

wwwwjprnet Vol 9 Issue 1 2020

1189

Subcutaneous Layer

The subcutaneous layer is beneath the dermis and consists mainly of a type of connective

tissue called Adipose tissue Adipose tissue is more commonly known as fat and helps

cushion the skin and provide protection from cold and temperature fluctuations

Rational approaches to drug delivery in the skin

There are two main ways to attack the problem of formulating a successful topical dosage

form

Directing drugs to the viable skin tissue without using oral systemic or other routes of

therapy

The other approaches use skin delivery for systemic treatment For example transdermal

therapeutic system provides systemic therapy for conditions such as motion sickness and

pain

Gels[13]

Topical gel formulations are of increasing interest in the dermatology industry Gel

formulations are typically transparent or translucent water-based semisolids with good

spreading properties and pleasing aesthetic characteristics

Delivery of drugs to the skin is an effective and targeted therapy for local dermatological

disorders This route of drug delivery has gained popularity because it avoids first pass

effects gastrointestinal irritation and metabolic degradation associated with oral

administration[5]

Due to the first past effect only 25-45 of the orally administered dose

reaches the blood circulation In order to bypass these disadvantages the gel formulations

have been proposed as topical application[6]

Topical gel formulations provide a suitable

delivery system for drugs because they are less greasy and can be easily removed from

the skin Percutaneous absorption of drugs from topical formulations involves the release

of the drug from the formulation and permeation through skin to reach the target tissue

The release of the drug from topical preparations depends on the physicochemical

properties of the vehicle and the drug employed In order to enhance drug release and skin

permeation methods such as the selection of a suitable vehicle co-administration of a

chemical enhancer[7]

have been studied Gel base formulation makes the drug molecules

more easily removable from the system than cream and ointment[89]

Gels for

dermatological use have several favorable properties such as being thixotropic

Rizwan et al World Journal of Pharmaceutical Research

wwwwjprnet Vol 9 Issue 1 2020

1190

greaseless easily spreadable easily removable emollient non-staining compatible with

several excipients and water-soluble or miscible[10]

Guggul and Boswellic acid when presented in the form of topical gel can reduce local

inflammations and arthritis Hence for local inflammation or pain in the body the topical

application of Guggul and Boswellic acid may be useful which also avoids the side

effects associated with the oral therapy Hence a topical gel containing Guggul and

Boswellic acid was prepared[11]

It is established that gel formulations are superior topical

formulation over any other topical formulations because these system have better

application property in comparison to creams and ointments[12]

In the present study the product which was selected is herbal gel The term gel oriented

during the late 1800rsquos as chemists attempted to classify semisolid substances according to

their molecule compositions At that time analytical method needed to determines

chemical structures were lacking Gels and jellies are composed of small amount of solid

dispersed in relatively large amount liquid yet they possess more solid like than liquid

like character In general gels and jellies are rigid enough to maintain their shapes under

a small applied stress

The United States Pharmacopoeia (USP) defines gels as semisolid being either

suspensions of small inorganic particles or large organic molecules interpenetrated with

liquid[14]

It is the interaction between units of the colloidal phase inorganic or organic

that set up the structural viscosity immobilizing liquid the continuous phase[15]

Thus gel

exhibit characteristics intermediate to those of liquid and solids[16]

Classification of gels

Gels are classified into different types based on the characteristics they possess[17]

1 Based on the nature of colloidal phase

a Inorganic gel - Examples Bentonite magma

b Organogel - Examples Polymer gel

These are further subdivided into different sub category according to chemicals nature of

dispersed organic molecules

Natural gums - Example Acacia Carrageenan Xanthan gum etc

Cellulosic derivatives - Examples Sodium carboxymethyl cellulose Hydroxyl ethyl

cellulose Hydroxyl propyl cellulose

Polyethylene and its co-polymer

mass was exhausted with hot water the residue was collected on an ashless filter paper the

residue and the filter paper was incinerated until the ash was white or nearly so the filtrate

was added evaporated to dryness and ignited at a temperature not exceeding 450ordmC The

percentage of ash was calculated with reference to their air dried drug

Moisture content Water content is determined by removing the moisture and then by

measuring weight loss

Successive solvent extraction of resin[40]

The resin Commiphora mukul was taken and loaded in soxhlet extractor and extracted with

ethyl acetate about five times the weight of gum The temp is kept at 65-70degC The extracted

fluid is taken for solvent recovery The oleoresin (thick paste) obtained after solvent removal

was purified for enrichment of guggulsterones by solvent frication method 2 g sample of

guggul extract was taken in 250 mL round bottom flask 35 mL of 05 M alcoholic KOH was

added and reflux for 90 min on a water bath The content of flask was transferred to a

separator rinsed the flask with 50 mL lukewarm water Extracted while the liquid was warm

by shaking vigorously with three successive quantities of 50 mL petroleum ether (60-80deg)

Then combine the petroleum ether layers and wash with 20 mL water Evaporated the

petroleum ether and weighed the residue

Preliminary phytochemical screening of petroleum ether extract of resin of commiphora

mukul[41]

The plants may be considered as a biosynthetic laboratory for a multitude of compounds like

alkaloids triterpenoids glycosides volatile oils tannins saponins sugars etc that exert

physiological effects These compounds are responsible for therapeutic effects usually the

secondary metabolites The petroleum extracts of Commiphora mukul was subjected to

preliminary phytochemical screening for the detection of various plant constituents The

different phytochemical test are as follows

Tests for sterols alkaloids saponins tannins flavonoids proteins amino acids sugars

Thin layer chromatography study[42 43]

Active extracts those having promising antimicrobial and antifungal activitywere subjected to

thin layer chromatography to find out the number of compounds present in them The details

of the procedure were as follows

A Preparation of the plates

The adsorbent used for thin layer chromatography was silica gel G About 25 g of silica gel G

was taken in a glass mortar and about 35 ml of distilled water was added to it This mixture

was then allowed to swell for 15 minutes The mixture was stirred with glass rod until it

becomes homogeneous Then an additional 15 ml of distilled water was added to it with

stirring The suspension was then transferred to a 150 ml flask fitted with a plastic stopper

and was shaken vigorously for about 2 minutes This suspension was then spreaded

immediately on thin layer chromatographic plates with the help of a thin layer

chromatography (TLC) applicator (SUPERFIT) of Continental Instruments Bombay was

used

B Drying and storage of plates

The freshly coated plates were then air dried until the transparency of the layer had

disappeared The plates were then stacked in a drying rack and were activated in an oven for

30 minutes at 110C The activated plates were then kept ina dessicator till required for

further use

C Application of the sample

For applying test samples on TLC plates glass capillaries were used The spots were applied

with the help of a fine capillary keeping a minimum distance of 1 cm between the two

adjacent spots The spots of the samples were marked on the top of the plate to know their

identity

D Chromatographic chamber conditions of saturation and the development of TLC

plates

Chromatographic rectangular glass chamber (165 x 295 cm) was used in the experiments

To avoid insufficient chamber saturation and the undesirable edge effect a smooth sheet of

filter paper approximately of 15 x 40 cm size was placed in the chromatographic chamber in

a U shape and was allowed to be soaked in the developing solvent After being thus

moistened the paper was then pressed against the walls of the chamber so that it adhered to

the walls The chamber was allowed to saturate for 24 hours before use The experiments

were carried out at room temperature in diffused daylight

E Developing solvent system

A number of developing solvent systems were tried for each residue but the satisfactory

resolution was obtained in the solvent systems mentioned in table TLC results obtained in

these systems are as shown in Table 6

F Spraying equipment

Compressed air sprayer with a fine nozzle was used to detect the different constituents

present on TLC plates Air compressor was attached to a glass sprayer The sprayer was filled

with about 50 ml of the detection reagent and then used After each spray the sprayer was

washed separately with water chromic acid and distilled water and then with acetone

G Detection of The Spots

Spots were detected using UV light (UV Chamber) and spraying (50) H2SO4

The Spreadability of the formulation was determined by an apparatus suggested by muttimer

et al which was suitably modified in the laboratory and used for the study It consists of a

wooden block which was provided by a pulley at one end A rectangular ground glass plate

was fixed on this block An excess of gel (about 1 g) under the study was placed on this

ground plate The gel was then sandwiched between this plate and another glass plate having

the dimension of fixed ground plate and provided with the hook A 1 kg weight was placed

on the top of two plates for 5 minutes to expel air and to provide a uniform film of the gel

between the plates Excess of gel was scrapped off from the edges The top plate was then

subjected to pull of 10g with the help of string attached to the hook and the time (in second)

required by the top plate to cover a distance of 5 cm was noted

Carrageenan induced rat paw edema model volume was used to assess the anti-inflammatory

activity of developed herbal carbopol gel Left hind paws of each Rat were just marked

beyond the tibiotarsal junction so that every time the paw is dipped up to the fixed mark to

ensure constant paw volume The rats (180ndash200g) were randomly divided into 3 groups of 3

rats each Group A normal received normal saline only Edema was induced in the remaining

groups B-CGroup B (toxic control) received carrageenan only without the drug The C

received an application of herbal gel (1g) andor treatment plantar injection of 01 mL of a

1 carageenan wv freshly prepare carageenan in normal saline was given into the left hind

paw of each rat After One hour the gel was applied to the left hind paw of each rat of treated

group Measurements of the paw volume up to the ankle joint were performed before and at

different time intervals (1 2 3 4 5 6 8 10 12h) following the Carrageenan injection using

plethysmometer

Percentage reduction calculated in edema was as follows

Inhibition = Edema (Control) minus Edema (Formulation Treated)

Edema (Control)

Arthritis Activity

Arthritis was induced in rats by subplannter injection of CFA(01 mlrat) in the right hind

paw Rats receiving CFA did not show any sign of acute toxicity Control animals were

injected with 09 saline On day 8 after adjuvant injection these rats were divided in

treatment groups (n = 6 ratsgroup) and injected daily with saline or agmatine 10 20 and 40

mgkg intraperitoneallyupto day 15 The animals were weighed daily The injections were

given daily in between 0900 and 1000 h and animals were subjected to measurement of

arthritis score[68]

as described below Thereafter they were shifted to their cages and the pre-

weighed food pellets were placed inside the cage hopper The food consumed by rats was

quantified by weighing leftover food in the hopper

Arthritis score

Evaluation of arthritis severity was performed by measuring the arthritis index of each

animal which was scored by grading eachpaw from 0 to 4 as described previously[68]

4 SUMMARY AND CONCLUSION

Boswellia serrata and Commiphora mukul is an anti-inflammatory and anti-arthritic drugs

used in the treatment of joint pain inflammation and arthritis The purpose of the topical and

dermatological dosage form is to conveniently deliver drug molecules across localized area of

skin Sustained release becomes important to supply the skin with a drug over a prolonged

period of time hence a dermatological delivery system such as gel was considered to be

formulated Beside this gel form may reduce the frequency of dosing intervals and may

improve patient compliance The preliminary phytochemical screening of the extract was

done in view to know the various classes of chemical constituents i e secondary metabolites

From the results of the phytochemical screening of the extracts it was observed that the

fractional product of Commiphora mukul resin contained triterpenoids and sterols

Development of gel was done by using carbapol 934 which was analyzed with a smooth and

homogeneous appearance It was easily spreadable with an acceptable mechanical property

The observation of pH revealed that all the formulations were very near to skin pH make it

suitable for application on skin The results obtained from present work indicated that the

entire drug was uniformly distributed and there was no precipitation in formulation For the

incorporation of drugs five formulae for gel were tried During comparison of these

formulae it was observed that formula 3 showed the smooth texture optimum pH and good

spreadability Hence formula 3 was taken for further studies In vitro drug release of

Boswellic acid and Guggulsterones from gel was performed to study the release behavior of

drug from formulation From the observed results it was concluded that there is increase in

the drug release with respect to time From a patient compliance point of view spreadability

is a important for topical drug delivery system The gel was found to exhibit good percentage

spread by weight that would assure the skin application Anti-Inflammatory Anti-Arthritic

study and Arthritis scoring of the prepared gel formulation evident the Anti-Arthritic activity

of the prepared herbal gel formulation Temperature stability study was performed to evaluate

the separation as well as precipitation of the drug in the excipients mixture It was observed

that the formulation was stable at different temperatures (room temperature cool

temperature elevated temperature and at 75 RH) for 60 days

In the present work the attempt was made to formulate and evaluate a gel for anti-arthritic

activity using extracts of Boswellia serrata and Commiphora mukul The results showed that

the content of Gel components had significant effect on their physical rheological and in

vitro drug release characteristics

Proposed Therapy

Herbal medicine provides another approach for treatment of RA and currently a number of

medicinal plants are under scientific evaluation to develop a novel drug There is a dire need

to investigate the complete therapeutic potential and adverse effects if any of these herbals

for providing newer and safer treatment options with minimum side effects

The proposed therapy represents the combination of the following two herbal medicines for

treatment of rheumatoid arthritis in gel form

Commiphora mukul (Guggul)

Boswellia serrata

Skin as a drug delivery target[22 23]

Human skin is essentially composed of two major layers an outer unvascularized epithelial

layer (the epidermis) which contains a rich supply of capillaries sweat glands nerves

sebaceous glands and hair follicles that are supported by connective tissue

Epidermis

It is the outermost multilayer of the skin Its thickness varies depending on number of cells it

contains and its position on the body The multilayered epidermis varies in thickness ranging

from about 08 mm on the palms and soles to 006 mm on the eyelids The different layers of

the epidermis represent the different stages of differentiation of stem cells migrating towards

the surface

Rizwan et al World Journal of Pharmaceutical Research

wwwwjprnet Vol 9 Issue 1 2020

1188

Fig 13 Component of the Epidermis and Dermis of Human Skin

Moving downwards the epidermis is made up of five layers

Stratum corneum (horney layer)

Stratum granulosum (granular layer)

Stratum Malphigion (spin sumpigment layer)

Stratum granulosum (basal layer)

Stratum lucidum

The superficial layer of epidermis and also the final stage of differentiation the stratum

corneumis formed from several layer of dead cells embedded in the lipid matrix It is almost

impermeable and is important in controlling the percutaneous absorption of drugs and other

chemicals

Dermis

The dermis (corneum) 3-5 mm thick consist of matrix of connective tissue woven from

fibrous protein (collagen elastin and reticulin) that is embedded in an amorphous ground of

substances called as mucopolysaccharides nerves blood vessels and lymphaticrsquos traverse the

matrix and appendages pierce it It needs an efficient blood supply to convey nutrients

remove waste products regulate temperature and pressure mobilize skin force and contribute

to skin colour

Rizwan et al World Journal of Pharmaceutical Research

wwwwjprnet Vol 9 Issue 1 2020

1189

Subcutaneous Layer

The subcutaneous layer is beneath the dermis and consists mainly of a type of connective

tissue called Adipose tissue Adipose tissue is more commonly known as fat and helps

cushion the skin and provide protection from cold and temperature fluctuations

Rational approaches to drug delivery in the skin

There are two main ways to attack the problem of formulating a successful topical dosage

form

Directing drugs to the viable skin tissue without using oral systemic or other routes of

therapy

The other approaches use skin delivery for systemic treatment For example transdermal

therapeutic system provides systemic therapy for conditions such as motion sickness and

pain

Gels[13]

Topical gel formulations are of increasing interest in the dermatology industry Gel

formulations are typically transparent or translucent water-based semisolids with good

spreading properties and pleasing aesthetic characteristics

Delivery of drugs to the skin is an effective and targeted therapy for local dermatological

disorders This route of drug delivery has gained popularity because it avoids first pass

effects gastrointestinal irritation and metabolic degradation associated with oral

administration[5]

Due to the first past effect only 25-45 of the orally administered dose

reaches the blood circulation In order to bypass these disadvantages the gel formulations

have been proposed as topical application[6]

Topical gel formulations provide a suitable

delivery system for drugs because they are less greasy and can be easily removed from

the skin Percutaneous absorption of drugs from topical formulations involves the release

of the drug from the formulation and permeation through skin to reach the target tissue

The release of the drug from topical preparations depends on the physicochemical

properties of the vehicle and the drug employed In order to enhance drug release and skin

permeation methods such as the selection of a suitable vehicle co-administration of a

chemical enhancer[7]

have been studied Gel base formulation makes the drug molecules

more easily removable from the system than cream and ointment[89]

Gels for

dermatological use have several favorable properties such as being thixotropic

Rizwan et al World Journal of Pharmaceutical Research

wwwwjprnet Vol 9 Issue 1 2020

1190

greaseless easily spreadable easily removable emollient non-staining compatible with

several excipients and water-soluble or miscible[10]

Guggul and Boswellic acid when presented in the form of topical gel can reduce local

inflammations and arthritis Hence for local inflammation or pain in the body the topical

application of Guggul and Boswellic acid may be useful which also avoids the side

effects associated with the oral therapy Hence a topical gel containing Guggul and

Boswellic acid was prepared[11]

It is established that gel formulations are superior topical

formulation over any other topical formulations because these system have better

application property in comparison to creams and ointments[12]

In the present study the product which was selected is herbal gel The term gel oriented

during the late 1800rsquos as chemists attempted to classify semisolid substances according to

their molecule compositions At that time analytical method needed to determines

chemical structures were lacking Gels and jellies are composed of small amount of solid

dispersed in relatively large amount liquid yet they possess more solid like than liquid

like character In general gels and jellies are rigid enough to maintain their shapes under

a small applied stress

The United States Pharmacopoeia (USP) defines gels as semisolid being either

suspensions of small inorganic particles or large organic molecules interpenetrated with

liquid[14]

It is the interaction between units of the colloidal phase inorganic or organic

that set up the structural viscosity immobilizing liquid the continuous phase[15]

Thus gel

exhibit characteristics intermediate to those of liquid and solids[16]

Classification of gels

Gels are classified into different types based on the characteristics they possess[17]

1 Based on the nature of colloidal phase

a Inorganic gel - Examples Bentonite magma

b Organogel - Examples Polymer gel

These are further subdivided into different sub category according to chemicals nature of

dispersed organic molecules

Natural gums - Example Acacia Carrageenan Xanthan gum etc

Cellulosic derivatives - Examples Sodium carboxymethyl cellulose Hydroxyl ethyl

cellulose Hydroxyl propyl cellulose

Polyethylene and its co-polymer

mass was exhausted with hot water the residue was collected on an ashless filter paper the

residue and the filter paper was incinerated until the ash was white or nearly so the filtrate

was added evaporated to dryness and ignited at a temperature not exceeding 450ordmC The

percentage of ash was calculated with reference to their air dried drug

Moisture content Water content is determined by removing the moisture and then by

measuring weight loss

Successive solvent extraction of resin[40]

The resin Commiphora mukul was taken and loaded in soxhlet extractor and extracted with

ethyl acetate about five times the weight of gum The temp is kept at 65-70degC The extracted

fluid is taken for solvent recovery The oleoresin (thick paste) obtained after solvent removal

was purified for enrichment of guggulsterones by solvent frication method 2 g sample of

guggul extract was taken in 250 mL round bottom flask 35 mL of 05 M alcoholic KOH was

added and reflux for 90 min on a water bath The content of flask was transferred to a

separator rinsed the flask with 50 mL lukewarm water Extracted while the liquid was warm

by shaking vigorously with three successive quantities of 50 mL petroleum ether (60-80deg)

Then combine the petroleum ether layers and wash with 20 mL water Evaporated the

petroleum ether and weighed the residue

Extraction Procedure

The collected resin was dried in a shade and powdered coarsely and was taken for soxhlet

extraction as shown in Figure 26

Preliminary phytochemical screening of petroleum ether extract of resin of commiphora

mukul[41]

The plants may be considered as a biosynthetic laboratory for a multitude of compounds like

alkaloids triterpenoids glycosides volatile oils tannins saponins sugars etc that exert

physiological effects These compounds are responsible for therapeutic effects usually the

secondary metabolites The petroleum extracts of Commiphora mukul was subjected to

preliminary phytochemical screening for the detection of various plant constituents The

different phytochemical test are as follows

Tests for sterols alkaloids saponins tannins flavonoids proteins amino acids sugars

Thin layer chromatography study[42 43]

Active extracts those having promising antimicrobial and antifungal activitywere subjected to

thin layer chromatography to find out the number of compounds present in them The details

of the procedure were as follows

A Preparation of the plates

The adsorbent used for thin layer chromatography was silica gel G About 25 g of silica gel G

was taken in a glass mortar and about 35 ml of distilled water was added to it This mixture

was then allowed to swell for 15 minutes The mixture was stirred with glass rod until it

becomes homogeneous Then an additional 15 ml of distilled water was added to it with

stirring The suspension was then transferred to a 150 ml flask fitted with a plastic stopper

and was shaken vigorously for about 2 minutes This suspension was then spreaded

immediately on thin layer chromatographic plates with the help of a thin layer

chromatography (TLC) applicator (SUPERFIT) of Continental Instruments Bombay was

used

B Drying and storage of plates

The freshly coated plates were then air dried until the transparency of the layer had

disappeared The plates were then stacked in a drying rack and were activated in an oven for

30 minutes at 110C The activated plates were then kept ina dessicator till required for

further use

C Application of the sample

For applying test samples on TLC plates glass capillaries were used The spots were applied

with the help of a fine capillary keeping a minimum distance of 1 cm between the two

adjacent spots The spots of the samples were marked on the top of the plate to know their

identity

D Chromatographic chamber conditions of saturation and the development of TLC

plates

Chromatographic rectangular glass chamber (165 x 295 cm) was used in the experiments

To avoid insufficient chamber saturation and the undesirable edge effect a smooth sheet of

filter paper approximately of 15 x 40 cm size was placed in the chromatographic chamber in

a U shape and was allowed to be soaked in the developing solvent After being thus

moistened the paper was then pressed against the walls of the chamber so that it adhered to

the walls The chamber was allowed to saturate for 24 hours before use The experiments

were carried out at room temperature in diffused daylight

E Developing solvent system

A number of developing solvent systems were tried for each residue but the satisfactory

resolution was obtained in the solvent systems mentioned in table TLC results obtained in

these systems are as shown in Table 6

F Spraying equipment

Compressed air sprayer with a fine nozzle was used to detect the different constituents

present on TLC plates Air compressor was attached to a glass sprayer The sprayer was filled

with about 50 ml of the detection reagent and then used After each spray the sprayer was

washed separately with water chromic acid and distilled water and then with acetone

G Detection of The Spots

Spots were detected using UV light (UV Chamber) and spraying (50) H2SO4

Determination of pH

The pH meter was calibrated with buffered solution at 40 70 and 92 before starting pH

determination The glass electrode of the pH meter was immersed into the 50 ml beaker

containing 50 g gel and pH was noted

Homogeneacity

Homogeneacity was checked by visual inspection

Spreadability

The Spreadability of the formulation was determined by an apparatus suggested by muttimer

et al which was suitably modified in the laboratory and used for the study It consists of a

wooden block which was provided by a pulley at one end A rectangular ground glass plate

was fixed on this block An excess of gel (about 1 g) under the study was placed on this

ground plate The gel was then sandwiched between this plate and another glass plate having

the dimension of fixed ground plate and provided with the hook A 1 kg weight was placed

on the top of two plates for 5 minutes to expel air and to provide a uniform film of the gel

between the plates Excess of gel was scrapped off from the edges The top plate was then

subjected to pull of 10g with the help of string attached to the hook and the time (in second)

required by the top plate to cover a distance of 5 cm was noted

Edema (Control)

Arthritis Activity

Arthritis was induced in rats by subplannter injection of CFA(01 mlrat) in the right hind

paw Rats receiving CFA did not show any sign of acute toxicity Control animals were

injected with 09 saline On day 8 after adjuvant injection these rats were divided in

treatment groups (n = 6 ratsgroup) and injected daily with saline or agmatine 10 20 and 40

mgkg intraperitoneallyupto day 15 The animals were weighed daily The injections were

given daily in between 0900 and 1000 h and animals were subjected to measurement of

arthritis score[68]

as described below Thereafter they were shifted to their cages and the pre-

weighed food pellets were placed inside the cage hopper The food consumed by rats was

quantified by weighing leftover food in the hopper

Arthritis score

Evaluation of arthritis severity was performed by measuring the arthritis index of each

animal which was scored by grading eachpaw from 0 to 4 as described previously[68]

Grading was determined as follows

Table 23 Arthritis Score

Score Sign

0 No erythema or swelling

1 Slight erythema or swelling of one or more digits

2 Swelling of the entire paw

3 Erythema and swelling of the ankle

4 Ankylosis incapacity to bend the ankle

The severity score was the sum of the arthritis scores of the right hind limb maximum upto 4

On day 15 after adjuvant injection blood was withdrawn by retro-orbital method for

biochemical analysis

Paw Volume

The paw volumes of all animals were measured daily till day 15using a plethysmometer (VJ

instrument India) The change in pawvolume was measured as the difference between the

final and initial paw volumes

Stability studies[6970]

Stability studies of drug product being as a part of drug discovery and ends with the

commercial products to assess the drug and formulation stability stability study were carried

out for most satisfactory formulation was sealed in glass vial and kept at 30 plusmn2ordmC and 40

4 SUMMARY AND CONCLUSION

Boswellia serrata and Commiphora mukul is an anti-inflammatory and anti-arthritic drugs

used in the treatment of joint pain inflammation and arthritis The purpose of the topical and

dermatological dosage form is to conveniently deliver drug molecules across localized area of

skin Sustained release becomes important to supply the skin with a drug over a prolonged

period of time hence a dermatological delivery system such as gel was considered to be

1213

formulated Beside this gel form may reduce the frequency of dosing intervals and may

improve patient compliance The preliminary phytochemical screening of the extract was

done in view to know the various classes of chemical constituents i e secondary metabolites

From the results of the phytochemical screening of the extracts it was observed that the

fractional product of Commiphora mukul resin contained triterpenoids and sterols

Development of gel was done by using carbapol 934 which was analyzed with a smooth and

homogeneous appearance It was easily spreadable with an acceptable mechanical property

The observation of pH revealed that all the formulations were very near to skin pH make it

suitable for application on skin The results obtained from present work indicated that the

entire drug was uniformly distributed and there was no precipitation in formulation For the

incorporation of drugs five formulae for gel were tried During comparison of these

formulae it was observed that formula 3 showed the smooth texture optimum pH and good

spreadability Hence formula 3 was taken for further studies In vitro drug release of

Boswellic acid and Guggulsterones from gel was performed to study the release behavior of

drug from formulation From the observed results it was concluded that there is increase in

the drug release with respect to time From a patient compliance point of view spreadability

is a important for topical drug delivery system The gel was found to exhibit good percentage

spread by weight that would assure the skin application Anti-Inflammatory Anti-Arthritic

study and Arthritis scoring of the prepared gel formulation evident the Anti-Arthritic activity

of the prepared herbal gel formulation Temperature stability study was performed to evaluate

the separation as well as precipitation of the drug in the excipients mixture It was observed

that the formulation was stable at different temperatures (room temperature cool

temperature elevated temperature and at 75 RH) for 60 days

In the present work the attempt was made to formulate and evaluate a gel for anti-arthritic

activity using extracts of Boswellia serrata and Commiphora mukul The results showed that

the content of Gel components had significant effect on their physical rheological and in

vitro drug release characteristics

Fig 13 Component of the Epidermis and Dermis of Human Skin

Moving downwards the epidermis is made up of five layers

Stratum corneum (horney layer)

Stratum granulosum (granular layer)

Stratum Malphigion (spin sumpigment layer)

Stratum granulosum (basal layer)

Stratum lucidum

The superficial layer of epidermis and also the final stage of differentiation the stratum

corneumis formed from several layer of dead cells embedded in the lipid matrix It is almost

impermeable and is important in controlling the percutaneous absorption of drugs and other

chemicals

Dermis

The dermis (corneum) 3-5 mm thick consist of matrix of connective tissue woven from

fibrous protein (collagen elastin and reticulin) that is embedded in an amorphous ground of

substances called as mucopolysaccharides nerves blood vessels and lymphaticrsquos traverse the

matrix and appendages pierce it It needs an efficient blood supply to convey nutrients

remove waste products regulate temperature and pressure mobilize skin force and contribute

to skin colour

Rizwan et al World Journal of Pharmaceutical Research

wwwwjprnet Vol 9 Issue 1 2020

Subcutaneous Layer

The subcutaneous layer is beneath the dermis and consists mainly of a type of connective

tissue called Adipose tissue Adipose tissue is more commonly known as fat and helps

cushion the skin and provide protection from cold and temperature fluctuations

Rational approaches to drug delivery in the skin

There are two main ways to attack the problem of formulating a successful topical dosage

form

Directing drugs to the viable skin tissue without using oral systemic or other routes of

therapy

The other approaches use skin delivery for systemic treatment For example transdermal

therapeutic system provides systemic therapy for conditions such as motion sickness and

pain

Gels[13]

Topical gel formulations are of increasing interest in the dermatology industry Gel

formulations are typically transparent or translucent water-based semisolids with good

spreading properties and pleasing aesthetic characteristics

Delivery of drugs to the skin is an effective and targeted therapy for local dermatological

disorders This route of drug delivery has gained popularity because it avoids first pass

effects gastrointestinal irritation and metabolic degradation associated with oral

administration[5]

Due to the first past effect only 25-45 of the orally administered dose

reaches the blood circulation In order to bypass these disadvantages the gel formulations

have been proposed as topical application[6]

Topical gel formulations provide a suitable

delivery system for drugs because they are less greasy and can be easily removed from

the skin Percutaneous absorption of drugs from topical formulations involves the release

of the drug from the formulation and permeation through skin to reach the target tissue

The release of the drug from topical preparations depends on the physicochemical

properties of the vehicle and the drug employed In order to enhance drug release and skin

permeation methods such as the selection of a suitable vehicle co-administration of a

chemical enhancer[7]

have been studied Gel base formulation makes the drug molecules

more easily removable from the system than cream and ointment[89]

Gels for

dermatological use have several favorable properties such as being thixotropic

Rizwan et al World Journal of Pharmaceutical Research

wwwwjprnet Vol 9 Issue 1 2020

1190

greaseless easily spreadable easily removable emollient non-staining compatible with

several excipients and water-soluble or miscible[10]

Guggul and Boswellic acid when presented in the form of topical gel can reduce local

inflammations and arthritis Hence for local inflammation or pain in the body the topical

application of Guggul and Boswellic acid may be useful which also avoids the side

effects associated with the oral therapy Hence a topical gel containing Guggul and

Boswellic acid was prepared[11]

It is established that gel formulations are superior topical

formulation over any other topical formulations because these system have better

application property in comparison to creams and ointments[12]

In the present study the product which was selected is herbal gel The term gel oriented

during the late 1800rsquos as chemists attempted to classify semisolid substances according to

their molecule compositions At that time analytical method needed to determines

chemical structures were lacking Gels and jellies are composed of small amount of solid

dispersed in relatively large amount liquid yet they possess more solid like than liquid

like character In general gels and jellies are rigid enough to maintain their shapes under

a small applied stress

The United States Pharmacopoeia (USP) defines gels as semisolid being either

suspensions of small inorganic particles or large organic molecules interpenetrated with

liquid[14]

It is the interaction between units of the colloidal phase inorganic or organic

that set up the structural viscosity immobilizing liquid the continuous phase[15]

Thus gel

exhibit characteristics intermediate to those of liquid and solids[16]

Classification of gels

Gels are classified into different types based on the characteristics they possess[17]

1 Based on the nature of colloidal phase

a Inorganic gel - Examples Bentonite magma

b Organogel - Examples Polymer gel

These are further subdivided into different sub category according to chemicals nature of

dispersed organic molecules

Natural gums - Example Acacia Carrageenan Xanthan gum etc

Cellulosic derivatives - Examples Sodium carboxymethyl cellulose Hydroxyl ethyl

cellulose Hydroxyl propyl cellulose

Polyethylene and its co-polymer

mass was exhausted with hot water the residue was collected on an ashless filter paper the

residue and the filter paper was incinerated until the ash was white or nearly so the filtrate

was added evaporated to dryness and ignited at a temperature not exceeding 450ordmC The

percentage of ash was calculated with reference to their air dried drug

Moisture content Water content is determined by removing the moisture and then by

measuring weight loss

Successive solvent extraction of resin[40]

The resin Commiphora mukul was taken and loaded in soxhlet extractor and extracted with

ethyl acetate about five times the weight of gum The temp is kept at 65-70degC The extracted

fluid is taken for solvent recovery The oleoresin (thick paste) obtained after solvent removal

was purified for enrichment of guggulsterones by solvent frication method 2 g sample of

guggul extract was taken in 250 mL round bottom flask 35 mL of 05 M alcoholic KOH was

added and reflux for 90 min on a water bath The content of flask was transferred to a

separator rinsed the flask with 50 mL lukewarm water Extracted while the liquid was warm

by shaking vigorously with three successive quantities of 50 mL petroleum ether (60-80deg)

Then combine the petroleum ether layers and wash with 20 mL water Evaporated the

petroleum ether and weighed the residue

Preliminary phytochemical screening of petroleum ether extract of resin of commiphora

mukul[41]

The plants may be considered as a biosynthetic laboratory for a multitude of compounds like

alkaloids triterpenoids glycosides volatile oils tannins saponins sugars etc that exert

physiological effects These compounds are responsible for therapeutic effects usually the

secondary metabolites The petroleum extracts of Commiphora mukul was subjected to

preliminary phytochemical screening for the detection of various plant constituents The

different phytochemical test are as follows

Tests for sterols alkaloids saponins tannins flavonoids proteins amino acids sugars

Thin layer chromatography study[42 43]

Active extracts those having promising antimicrobial and antifungal activitywere subjected to

thin layer chromatography to find out the number of compounds present in them The details

of the procedure were as follows

A Preparation of the plates

The adsorbent used for thin layer chromatography was silica gel G About 25 g of silica gel G

was taken in a glass mortar and about 35 ml of distilled water was added to it This mixture

was then allowed to swell for 15 minutes The mixture was stirred with glass rod until it

becomes homogeneous Then an additional 15 ml of distilled water was added to it with

stirring The suspension was then transferred to a 150 ml flask fitted with a plastic stopper

and was shaken vigorously for about 2 minutes This suspension was then spreaded

immediately on thin layer chromatographic plates with the help of a thin layer

chromatography (TLC) applicator (SUPERFIT) of Continental Instruments Bombay was

used

B Drying and storage of plates

The freshly coated plates were then air dried until the transparency of the layer had

disappeared The plates were then stacked in a drying rack and were activated in an oven for

30 minutes at 110C The activated plates were then kept ina dessicator till required for

further use

C Application of the sample

For applying test samples on TLC plates glass capillaries were used The spots were applied

with the help of a fine capillary keeping a minimum distance of 1 cm between the two

adjacent spots The spots of the samples were marked on the top of the plate to know their

identity

D Chromatographic chamber conditions of saturation and the development of TLC

plates

Chromatographic rectangular glass chamber (165 x 295 cm) was used in the experiments

To avoid insufficient chamber saturation and the undesirable edge effect a smooth sheet of

filter paper approximately of 15 x 40 cm size was placed in the chromatographic chamber in

a U shape and was allowed to be soaked in the developing solvent After being thus

moistened the paper was then pressed against the walls of the chamber so that it adhered to

the walls The chamber was allowed to saturate for 24 hours before use The experiments

were carried out at room temperature in diffused daylight

E Developing solvent system

A number of developing solvent systems were tried for each residue but the satisfactory

resolution was obtained in the solvent systems mentioned in table TLC results obtained in

these systems are as shown in Table 6

F Spraying equipment

Compressed air sprayer with a fine nozzle was used to detect the different constituents

present on TLC plates Air compressor was attached to a glass sprayer The sprayer was filled

with about 50 ml of the detection reagent and then used After each spray the sprayer was

washed separately with water chromic acid and distilled water and then with acetone

G Detection of The Spots

Spots were detected using UV light (UV Chamber) and spraying (50) H2SO4

All the above studies were carried out by using no special equipement these were done by

visual assessment

Identification of Pure Drug

The thin layer chromatography (TLC) method is used to identification of isolated compound

to standard compound or marker in which the Rf value was noted

Solubility studies

A solubility study was carried out to find out the solubility of drug in different solvents

According to this method the pure drug was added to the solvent medium and shaken for 2

hr The saturation was confirmed by observation of presence of undissolved material After

filtration of the slurry sample was analyzed using UV Visible spectrophotometer at 252 - 255

nm

Determination of pH

The pH meter was calibrated with buffered solution at 40 70 and 92 before starting pH

determination The glass electrode of the pH meter was immersed into the 50 ml beaker

containing 50 g gel and pH was noted

Homogeneacity

Homogeneacity was checked by visual inspection

Spreadability

The Spreadability of the formulation was determined by an apparatus suggested by muttimer

et al which was suitably modified in the laboratory and used for the study It consists of a

wooden block which was provided by a pulley at one end A rectangular ground glass plate

was fixed on this block An excess of gel (about 1 g) under the study was placed on this

ground plate The gel was then sandwiched between this plate and another glass plate having

the dimension of fixed ground plate and provided with the hook A 1 kg weight was placed

on the top of two plates for 5 minutes to expel air and to provide a uniform film of the gel

between the plates Excess of gel was scrapped off from the edges The top plate was then

subjected to pull of 10g with the help of string attached to the hook and the time (in second)

required by the top plate to cover a distance of 5 cm was noted

Skin irritancy test

This test was performed on human volunteers Twenty volunteers were chosen for single

formulation and study was performed after taking their informed consent It was performed

by applying gel on an area of 2 square inch to the back of hand Then the examination for the

presence of lesion or irritation was done

Drug Content Studies Accurately weighed 1 g of gel was transferred into 100 ml

volumetric flask containing 20 ml of saline phosphate buffer (pH 68) and stirred for 30 min

followed by sonication The volume was made up to 100 ml with saline phosphate buffer (pH

68) After suitable dilution the absorbance was measured using Shimadzu 1700 UV Visible

spectrophotometer at 210 ndash 215 nm

Viscosity measurement Viscosity of the gel was determined by using Brookfield

viscometer Accurately weighed 100 g of gel was transferred to 100 ml glass beaker Spindle

no S64 was selected and it is immersed into the gel The viscometer was operated at various

rpm until the reading gets stabilized and reading was noted in centipoises It was noted from

the literature that the formulations after gelling should have a viscosity of 50 ndash 50000 cps

In vivo anti-inflammatory activity[5152535455565758596061 62636465 6667]

Carrageenan induced rat paw edema model volume was used to assess the anti-inflammatory

activity of developed herbal carbopol gel Left hind paws of each Rat were just marked

beyond the tibiotarsal junction so that every time the paw is dipped up to the fixed mark to

ensure constant paw volume The rats (180ndash200g) were randomly divided into 3 groups of 3

rats each Group A normal received normal saline only Edema was induced in the remaining

groups B-CGroup B (toxic control) received carrageenan only without the drug The C

received an application of herbal gel (1g) andor treatment plantar injection of 01 mL of a

1 carageenan wv freshly prepare carageenan in normal saline was given into the left hind

paw of each rat After One hour the gel was applied to the left hind paw of each rat of treated

group Measurements of the paw volume up to the ankle joint were performed before and at

different time intervals (1 2 3 4 5 6 8 10 12h) following the Carrageenan injection using

plethysmometer

Percentage reduction calculated in edema was as follows

Inhibition = Edema (Control) minus Edema (Formulation Treated)

Edema (Control)

Arthritis Activity

Arthritis was induced in rats by subplannter injection of CFA(01 mlrat) in the right hind

paw Rats receiving CFA did not show any sign of acute toxicity Control animals were

injected with 09 saline On day 8 after adjuvant injection these rats were divided in

treatment groups (n = 6 ratsgroup) and injected daily with saline or agmatine 10 20 and 40

mgkg intraperitoneallyupto day 15 The animals were weighed daily The injections were

given daily in between 0900 and 1000 h and animals were subjected to measurement of

arthritis score[68]

as described below Thereafter they were shifted to their cages and the pre-

weighed food pellets were placed inside the cage hopper The food consumed by rats was

quantified by weighing leftover food in the hopper

Arthritis score

Evaluation of arthritis severity was performed by measuring the arthritis index of each

animal which was scored by grading eachpaw from 0 to 4 as described previously[68]

Grading was determined as follows

Rizwan et al World Journal of Pharmaceutical Research

wwwwjprnet Vol 9 Issue 1 2020

Table 23 Arthritis Score

Score Sign

0 No erythema or swelling

1 Slight erythema or swelling of one or more digits

2 Swelling of the entire paw

3 Erythema and swelling of the ankle

4 Ankylosis incapacity to bend the ankle

The severity score was the sum of the arthritis scores of the right hind limb maximum upto 4

On day 15 after adjuvant injection blood was withdrawn by retro-orbital method for

biochemical analysis

Paw Volume

The paw volumes of all animals were measured daily till day 15using a plethysmometer (VJ

instrument India) The change in pawvolume was measured as the difference between the

final and initial paw volumes

Stability studies[6970]

Stability studies of drug product being as a part of drug discovery and ends with the

commercial products to assess the drug and formulation stability stability study were carried

out for most satisfactory formulation was sealed in glass vial and kept at 30 plusmn2ordmC and 40

4 SUMMARY AND CONCLUSION

Boswellia serrata and Commiphora mukul is an anti-inflammatory and anti-arthritic drugs

used in the treatment of joint pain inflammation and arthritis The purpose of the topical and

dermatological dosage form is to conveniently deliver drug molecules across localized area of

skin Sustained release becomes important to supply the skin with a drug over a prolonged

period of time hence a dermatological delivery system such as gel was considered to be

1213

formulated Beside this gel form may reduce the frequency of dosing intervals and may

improve patient compliance The preliminary phytochemical screening of the extract was

done in view to know the various classes of chemical constituents i e secondary metabolites

From the results of the phytochemical screening of the extracts it was observed that the

fractional product of Commiphora mukul resin contained triterpenoids and sterols

Development of gel was done by using carbapol 934 which was analyzed with a smooth and

homogeneous appearance It was easily spreadable with an acceptable mechanical property

The observation of pH revealed that all the formulations were very near to skin pH make it

suitable for application on skin The results obtained from present work indicated that the

entire drug was uniformly distributed and there was no precipitation in formulation For the

incorporation of drugs five formulae for gel were tried During comparison of these

formulae it was observed that formula 3 showed the smooth texture optimum pH and good

spreadability Hence formula 3 was taken for further studies In vitro drug release of

Boswellic acid and Guggulsterones from gel was performed to study the release behavior of

drug from formulation From the observed results it was concluded that there is increase in

the drug release with respect to time From a patient compliance point of view spreadability

is a important for topical drug delivery system The gel was found to exhibit good percentage

spread by weight that would assure the skin application Anti-Inflammatory Anti-Arthritic

study and Arthritis scoring of the prepared gel formulation evident the Anti-Arthritic activity

of the prepared herbal gel formulation Temperature stability study was performed to evaluate

the separation as well as precipitation of the drug in the excipients mixture It was observed

that the formulation was stable at different temperatures (room temperature cool

temperature elevated temperature and at 75 RH) for 60 days

In the present work the attempt was made to formulate and evaluate a gel for anti-arthritic

activity using extracts of Boswellia serrata and Commiphora mukul The results showed that

the content of Gel components had significant effect on their physical rheological and in

vitro drug release characteristics

Subcutaneous Layer

The subcutaneous layer is beneath the dermis and consists mainly of a type of connective

tissue called Adipose tissue Adipose tissue is more commonly known as fat and helps

cushion the skin and provide protection from cold and temperature fluctuations

Rational approaches to drug delivery in the skin

There are two main ways to attack the problem of formulating a successful topical dosage

form

Directing drugs to the viable skin tissue without using oral systemic or other routes of

therapy

The other approaches use skin delivery for systemic treatment For example transdermal

therapeutic system provides systemic therapy for conditions such as motion sickness and

pain

Gels[13]

Topical gel formulations are of increasing interest in the dermatology industry Gel

formulations are typically transparent or translucent water-based semisolids with good

spreading properties and pleasing aesthetic characteristics

Delivery of drugs to the skin is an effective and targeted therapy for local dermatological

disorders This route of drug delivery has gained popularity because it avoids first pass

effects gastrointestinal irritation and metabolic degradation associated with oral

administration[5]

Due to the first past effect only 25-45 of the orally administered dose

reaches the blood circulation In order to bypass these disadvantages the gel formulations

have been proposed as topical application[6]

Topical gel formulations provide a suitable

delivery system for drugs because they are less greasy and can be easily removed from

the skin Percutaneous absorption of drugs from topical formulations involves the release

of the drug from the formulation and permeation through skin to reach the target tissue

The release of the drug from topical preparations depends on the physicochemical

properties of the vehicle and the drug employed In order to enhance drug release and skin

permeation methods such as the selection of a suitable vehicle co-administration of a

chemical enhancer[7]

have been studied Gel base formulation makes the drug molecules

more easily removable from the system than cream and ointment[89]

Gels for

dermatological use have several favorable properties such as being thixotropic

Rizwan et al World Journal of Pharmaceutical Research

wwwwjprnet Vol 9 Issue 1 2020

1190

greaseless easily spreadable easily removable emollient non-staining compatible with

several excipients and water-soluble or miscible[10]

Guggul and Boswellic acid when presented in the form of topical gel can reduce local

inflammations and arthritis Hence for local inflammation or pain in the body the topical

application of Guggul and Boswellic acid may be useful which also avoids the side

effects associated with the oral therapy Hence a topical gel containing Guggul and

Boswellic acid was prepared[11]

It is established that gel formulations are superior topical

formulation over any other topical formulations because these system have better

application property in comparison to creams and ointments[12]

In the present study the product which was selected is herbal gel The term gel oriented

during the late 1800rsquos as chemists attempted to classify semisolid substances according to

their molecule compositions At that time analytical method needed to determines

chemical structures were lacking Gels and jellies are composed of small amount of solid

dispersed in relatively large amount liquid yet they possess more solid like than liquid

like character In general gels and jellies are rigid enough to maintain their shapes under

a small applied stress

The United States Pharmacopoeia (USP) defines gels as semisolid being either

suspensions of small inorganic particles or large organic molecules interpenetrated with

liquid[14]

It is the interaction between units of the colloidal phase inorganic or organic

that set up the structural viscosity immobilizing liquid the continuous phase[15]

Thus gel

exhibit characteristics intermediate to those of liquid and solids[16]

Classification of gels

Gels are classified into different types based on the characteristics they possess[17]

1 Based on the nature of colloidal phase

a Inorganic gel - Examples Bentonite magma

b Organogel - Examples Polymer gel

These are further subdivided into different sub category according to chemicals nature of

dispersed organic molecules

Natural gums - Example Acacia Carrageenan Xanthan gum etc

Cellulosic derivatives - Examples Sodium carboxymethyl cellulose Hydroxyl ethyl

cellulose Hydroxyl propyl cellulose

Polyethylene and its co-polymer

mass was exhausted with hot water the residue was collected on an ashless filter paper the

residue and the filter paper was incinerated until the ash was white or nearly so the filtrate

was added evaporated to dryness and ignited at a temperature not exceeding 450ordmC The

percentage of ash was calculated with reference to their air dried drug

Moisture content Water content is determined by removing the moisture and then by

measuring weight loss

Successive solvent extraction of resin[40]

The resin Commiphora mukul was taken and loaded in soxhlet extractor and extracted with

ethyl acetate about five times the weight of gum The temp is kept at 65-70degC The extracted

fluid is taken for solvent recovery The oleoresin (thick paste) obtained after solvent removal

was purified for enrichment of guggulsterones by solvent frication method 2 g sample of

guggul extract was taken in 250 mL round bottom flask 35 mL of 05 M alcoholic KOH was

added and reflux for 90 min on a water bath The content of flask was transferred to a

separator rinsed the flask with 50 mL lukewarm water Extracted while the liquid was warm

by shaking vigorously with three successive quantities of 50 mL petroleum ether (60-80deg)

Then combine the petroleum ether layers and wash with 20 mL water Evaporated the

petroleum ether and weighed the residue

Extraction Procedure

The collected resin was dried in a shade and powdered coarsely and was taken for soxhlet

extraction as shown in Figure 26

Preliminary phytochemical screening of petroleum ether extract of resin of commiphora

mukul[41]

The plants may be considered as a biosynthetic laboratory for a multitude of compounds like

alkaloids triterpenoids glycosides volatile oils tannins saponins sugars etc that exert

physiological effects These compounds are responsible for therapeutic effects usually the

secondary metabolites The petroleum extracts of Commiphora mukul was subjected to

preliminary phytochemical screening for the detection of various plant constituents The

different phytochemical test are as follows

Tests for sterols alkaloids saponins tannins flavonoids proteins amino acids sugars

Thin layer chromatography study[42 43]

Active extracts those having promising antimicrobial and antifungal activitywere subjected to

thin layer chromatography to find out the number of compounds present in them The details

of the procedure were as follows

A Preparation of the plates

The adsorbent used for thin layer chromatography was silica gel G About 25 g of silica gel G

was taken in a glass mortar and about 35 ml of distilled water was added to it This mixture

was then allowed to swell for 15 minutes The mixture was stirred with glass rod until it

becomes homogeneous Then an additional 15 ml of distilled water was added to it with

stirring The suspension was then transferred to a 150 ml flask fitted with a plastic stopper

and was shaken vigorously for about 2 minutes This suspension was then spreaded

immediately on thin layer chromatographic plates with the help of a thin layer

chromatography (TLC) applicator (SUPERFIT) of Continental Instruments Bombay was

used

B Drying and storage of plates

The freshly coated plates were then air dried until the transparency of the layer had

disappeared The plates were then stacked in a drying rack and were activated in an oven for

30 minutes at 110C The activated plates were then kept ina dessicator till required for

further use

C Application of the sample

For applying test samples on TLC plates glass capillaries were used The spots were applied

with the help of a fine capillary keeping a minimum distance of 1 cm between the two

adjacent spots The spots of the samples were marked on the top of the plate to know their

identity

D Chromatographic chamber conditions of saturation and the development of TLC

plates

Chromatographic rectangular glass chamber (165 x 295 cm) was used in the experiments

To avoid insufficient chamber saturation and the undesirable edge effect a smooth sheet of

filter paper approximately of 15 x 40 cm size was placed in the chromatographic chamber in

a U shape and was allowed to be soaked in the developing solvent After being thus

moistened the paper was then pressed against the walls of the chamber so that it adhered to

the walls The chamber was allowed to saturate for 24 hours before use The experiments

were carried out at room temperature in diffused daylight

E Developing solvent system

A number of developing solvent systems were tried for each residue but the satisfactory

resolution was obtained in the solvent systems mentioned in table TLC results obtained in

these systems are as shown in Table 6

F Spraying equipment

Compressed air sprayer with a fine nozzle was used to detect the different constituents

present on TLC plates Air compressor was attached to a glass sprayer The sprayer was filled

with about 50 ml of the detection reagent and then used After each spray the sprayer was

washed separately with water chromic acid and distilled water and then with acetone

G Detection of The Spots

Spots were detected using UV light (UV Chamber) and spraying (50) H2SO4

All the above studies were carried out by using no special equipement these were done by

visual assessment

Identification of Pure Drug

The thin layer chromatography (TLC) method is used to identification of isolated compound

to standard compound or marker in which the Rf value was noted

Solubility studies

A solubility study was carried out to find out the solubility of drug in different solvents

According to this method the pure drug was added to the solvent medium and shaken for 2

hr The saturation was confirmed by observation of presence of undissolved material After

filtration of the slurry sample was analyzed using UV Visible spectrophotometer at 252 - 255

nm

Formulation development[444546]

Evaluation of Gel[474849]

Determination of pH

The pH meter was calibrated with buffered solution at 40 70 and 92 before starting pH

determination The glass electrode of the pH meter was immersed into the 50 ml beaker

containing 50 g gel and pH was noted

Homogeneacity

Homogeneacity was checked by visual inspection

Spreadability

The Spreadability of the formulation was determined by an apparatus suggested by muttimer

et al which was suitably modified in the laboratory and used for the study It consists of a

wooden block which was provided by a pulley at one end A rectangular ground glass plate

was fixed on this block An excess of gel (about 1 g) under the study was placed on this

ground plate The gel was then sandwiched between this plate and another glass plate having

the dimension of fixed ground plate and provided with the hook A 1 kg weight was placed

on the top of two plates for 5 minutes to expel air and to provide a uniform film of the gel

between the plates Excess of gel was scrapped off from the edges The top plate was then

subjected to pull of 10g with the help of string attached to the hook and the time (in second)

required by the top plate to cover a distance of 5 cm was noted

Skin irritancy test

This test was performed on human volunteers Twenty volunteers were chosen for single

formulation and study was performed after taking their informed consent It was performed

by applying gel on an area of 2 square inch to the back of hand Then the examination for the

presence of lesion or irritation was done

Drug Content Studies Accurately weighed 1 g of gel was transferred into 100 ml

volumetric flask containing 20 ml of saline phosphate buffer (pH 68) and stirred for 30 min

followed by sonication The volume was made up to 100 ml with saline phosphate buffer (pH

68) After suitable dilution the absorbance was measured using Shimadzu 1700 UV Visible

spectrophotometer at 210 ndash 215 nm

Viscosity measurement Viscosity of the gel was determined by using Brookfield

viscometer Accurately weighed 100 g of gel was transferred to 100 ml glass beaker Spindle

no S64 was selected and it is immersed into the gel The viscometer was operated at various

rpm until the reading gets stabilized and reading was noted in centipoises It was noted from

the literature that the formulations after gelling should have a viscosity of 50 ndash 50000 cps

In vitro diffusion studies[50]

In-vitrodiffusion study was carried out in a Modified Franz diffusion cell using cellophane

membrane which is heated for 1hr in boiling water The membrane was tied to the donor

compartment and mounted on the reservoir compartment of Franz diffusion cell containing

21 ml of pH 68 phosphate buffer 1 g of Boswellia serrate and Commiphoramukulgel was

placed over the cellophane membrane of donor compartment Whole set was placed on the

In vivo anti-inflammatory activity[5152535455565758596061 62636465 6667]

Carrageenan induced rat paw edema model volume was used to assess the anti-inflammatory

activity of developed herbal carbopol gel Left hind paws of each Rat were just marked

beyond the tibiotarsal junction so that every time the paw is dipped up to the fixed mark to

ensure constant paw volume The rats (180ndash200g) were randomly divided into 3 groups of 3

rats each Group A normal received normal saline only Edema was induced in the remaining

groups B-CGroup B (toxic control) received carrageenan only without the drug The C

received an application of herbal gel (1g) andor treatment plantar injection of 01 mL of a

1 carageenan wv freshly prepare carageenan in normal saline was given into the left hind

paw of each rat After One hour the gel was applied to the left hind paw of each rat of treated

group Measurements of the paw volume up to the ankle joint were performed before and at

different time intervals (1 2 3 4 5 6 8 10 12h) following the Carrageenan injection using

plethysmometer

Percentage reduction calculated in edema was as follows

Inhibition = Edema (Control) minus Edema (Formulation Treated)

Edema (Control)

Arthritis Activity

Arthritis was induced in rats by subplannter injection of CFA(01 mlrat) in the right hind

paw Rats receiving CFA did not show any sign of acute toxicity Control animals were

injected with 09 saline On day 8 after adjuvant injection these rats were divided in

treatment groups (n = 6 ratsgroup) and injected daily with saline or agmatine 10 20 and 40

mgkg intraperitoneallyupto day 15 The animals were weighed daily The injections were

given daily in between 0900 and 1000 h and animals were subjected to measurement of

arthritis score[68]

as described below Thereafter they were shifted to their cages and the pre-

weighed food pellets were placed inside the cage hopper The food consumed by rats was

quantified by weighing leftover food in the hopper

Arthritis score

Evaluation of arthritis severity was performed by measuring the arthritis index of each

animal which was scored by grading eachpaw from 0 to 4 as described previously[68]

Grading was determined as follows

Rizwan et al World Journal of Pharmaceutical Research

wwwwjprnet Vol 9 Issue 1 2020

Table 23 Arthritis Score

Score Sign

0 No erythema or swelling

1 Slight erythema or swelling of one or more digits

2 Swelling of the entire paw

3 Erythema and swelling of the ankle

4 Ankylosis incapacity to bend the ankle

The severity score was the sum of the arthritis scores of the right hind limb maximum upto 4

On day 15 after adjuvant injection blood was withdrawn by retro-orbital method for

biochemical analysis

Paw Volume

The paw volumes of all animals were measured daily till day 15using a plethysmometer (VJ

instrument India) The change in pawvolume was measured as the difference between the

final and initial paw volumes

Stability studies[6970]

Stability studies of drug product being as a part of drug discovery and ends with the

commercial products to assess the drug and formulation stability stability study were carried

out for most satisfactory formulation was sealed in glass vial and kept at 30 plusmn2ordmC and 40

4 SUMMARY AND CONCLUSION

Boswellia serrata and Commiphora mukul is an anti-inflammatory and anti-arthritic drugs

used in the treatment of joint pain inflammation and arthritis The purpose of the topical and

dermatological dosage form is to conveniently deliver drug molecules across localized area of

skin Sustained release becomes important to supply the skin with a drug over a prolonged

period of time hence a dermatological delivery system such as gel was considered to be

1213

formulated Beside this gel form may reduce the frequency of dosing intervals and may

improve patient compliance The preliminary phytochemical screening of the extract was

done in view to know the various classes of chemical constituents i e secondary metabolites

From the results of the phytochemical screening of the extracts it was observed that the

fractional product of Commiphora mukul resin contained triterpenoids and sterols

Development of gel was done by using carbapol 934 which was analyzed with a smooth and

homogeneous appearance It was easily spreadable with an acceptable mechanical property

The observation of pH revealed that all the formulations were very near to skin pH make it

suitable for application on skin The results obtained from present work indicated that the

entire drug was uniformly distributed and there was no precipitation in formulation For the

incorporation of drugs five formulae for gel were tried During comparison of these

formulae it was observed that formula 3 showed the smooth texture optimum pH and good

spreadability Hence formula 3 was taken for further studies In vitro drug release of

Boswellic acid and Guggulsterones from gel was performed to study the release behavior of

drug from formulation From the observed results it was concluded that there is increase in

the drug release with respect to time From a patient compliance point of view spreadability

is a important for topical drug delivery system The gel was found to exhibit good percentage

spread by weight that would assure the skin application Anti-Inflammatory Anti-Arthritic

study and Arthritis scoring of the prepared gel formulation evident the Anti-Arthritic activity

of the prepared herbal gel formulation Temperature stability study was performed to evaluate

the separation as well as precipitation of the drug in the excipients mixture It was observed

that the formulation was stable at different temperatures (room temperature cool

temperature elevated temperature and at 75 RH) for 60 days

In the present work the attempt was made to formulate and evaluate a gel for anti-arthritic

activity using extracts of Boswellia serrata and Commiphora mukul The results showed that

the content of Gel components had significant effect on their physical rheological and in

vitro drug release characteristics

greaseless easily spreadable easily removable emollient non-staining compatible with

several excipients and water-soluble or miscible[10]

Guggul and Boswellic acid when presented in the form of topical gel can reduce local

inflammations and arthritis Hence for local inflammation or pain in the body the topical

application of Guggul and Boswellic acid may be useful which also avoids the side

effects associated with the oral therapy Hence a topical gel containing Guggul and

Boswellic acid was prepared[11]

It is established that gel formulations are superior topical

formulation over any other topical formulations because these system have better

application property in comparison to creams and ointments[12]

In the present study the product which was selected is herbal gel The term gel oriented

during the late 1800rsquos as chemists attempted to classify semisolid substances according to

their molecule compositions At that time analytical method needed to determines

chemical structures were lacking Gels and jellies are composed of small amount of solid

dispersed in relatively large amount liquid yet they possess more solid like than liquid

like character In general gels and jellies are rigid enough to maintain their shapes under

a small applied stress

The United States Pharmacopoeia (USP) defines gels as semisolid being either

suspensions of small inorganic particles or large organic molecules interpenetrated with

liquid[14]

It is the interaction between units of the colloidal phase inorganic or organic

that set up the structural viscosity immobilizing liquid the continuous phase[15]

Thus gel

exhibit characteristics intermediate to those of liquid and solids[16]

Classification of gels

Gels are classified into different types based on the characteristics they possess[17]

1 Based on the nature of colloidal phase

a Inorganic gel - Examples Bentonite magma

b Organogel - Examples Polymer gel

These are further subdivided into different sub category according to chemicals nature of

dispersed organic molecules

Natural gums - Example Acacia Carrageenan Xanthan gum etc

Cellulosic derivatives - Examples Sodium carboxymethyl cellulose Hydroxyl ethyl

cellulose Hydroxyl propyl cellulose

Polyethylene and its co-polymer

mass was exhausted with hot water the residue was collected on an ashless filter paper the

residue and the filter paper was incinerated until the ash was white or nearly so the filtrate

was added evaporated to dryness and ignited at a temperature not exceeding 450ordmC The

percentage of ash was calculated with reference to their air dried drug

Moisture content Water content is determined by removing the moisture and then by

measuring weight loss

Successive solvent extraction of resin[40]

The resin Commiphora mukul was taken and loaded in soxhlet extractor and extracted with

ethyl acetate about five times the weight of gum The temp is kept at 65-70degC The extracted

fluid is taken for solvent recovery The oleoresin (thick paste) obtained after solvent removal

was purified for enrichment of guggulsterones by solvent frication method 2 g sample of

guggul extract was taken in 250 mL round bottom flask 35 mL of 05 M alcoholic KOH was

added and reflux for 90 min on a water bath The content of flask was transferred to a

separator rinsed the flask with 50 mL lukewarm water Extracted while the liquid was warm

by shaking vigorously with three successive quantities of 50 mL petroleum ether (60-80deg)

Then combine the petroleum ether layers and wash with 20 mL water Evaporated the

petroleum ether and weighed the residue

Extraction Procedure

Preliminary phytochemical screening of petroleum ether extract of resin of commiphora

mukul[41]

The plants may be considered as a biosynthetic laboratory for a multitude of compounds like

alkaloids triterpenoids glycosides volatile oils tannins saponins sugars etc that exert

physiological effects These compounds are responsible for therapeutic effects usually the

secondary metabolites The petroleum extracts of Commiphora mukul was subjected to

preliminary phytochemical screening for the detection of various plant constituents The

different phytochemical test are as follows

Tests for sterols alkaloids saponins tannins flavonoids proteins amino acids sugars

Thin layer chromatography study[42 43]

Active extracts those having promising antimicrobial and antifungal activitywere subjected to

thin layer chromatography to find out the number of compounds present in them The details

of the procedure were as follows

A Preparation of the plates

The adsorbent used for thin layer chromatography was silica gel G About 25 g of silica gel G

was taken in a glass mortar and about 35 ml of distilled water was added to it This mixture

was then allowed to swell for 15 minutes The mixture was stirred with glass rod until it

becomes homogeneous Then an additional 15 ml of distilled water was added to it with

stirring The suspension was then transferred to a 150 ml flask fitted with a plastic stopper

and was shaken vigorously for about 2 minutes This suspension was then spreaded

immediately on thin layer chromatographic plates with the help of a thin layer

chromatography (TLC) applicator (SUPERFIT) of Continental Instruments Bombay was

used

B Drying and storage of plates

The freshly coated plates were then air dried until the transparency of the layer had

disappeared The plates were then stacked in a drying rack and were activated in an oven for

30 minutes at 110C The activated plates were then kept ina dessicator till required for

further use

C Application of the sample

For applying test samples on TLC plates glass capillaries were used The spots were applied

with the help of a fine capillary keeping a minimum distance of 1 cm between the two

adjacent spots The spots of the samples were marked on the top of the plate to know their

identity

D Chromatographic chamber conditions of saturation and the development of TLC

plates

Chromatographic rectangular glass chamber (165 x 295 cm) was used in the experiments

To avoid insufficient chamber saturation and the undesirable edge effect a smooth sheet of

filter paper approximately of 15 x 40 cm size was placed in the chromatographic chamber in

a U shape and was allowed to be soaked in the developing solvent After being thus

moistened the paper was then pressed against the walls of the chamber so that it adhered to

the walls The chamber was allowed to saturate for 24 hours before use The experiments

were carried out at room temperature in diffused daylight

E Developing solvent system

A number of developing solvent systems were tried for each residue but the satisfactory

resolution was obtained in the solvent systems mentioned in table TLC results obtained in

these systems are as shown in Table 6

F Spraying equipment

Compressed air sprayer with a fine nozzle was used to detect the different constituents

present on TLC plates Air compressor was attached to a glass sprayer The sprayer was filled

with about 50 ml of the detection reagent and then used After each spray the sprayer was

washed separately with water chromic acid and distilled water and then with acetone

G Detection of The Spots

Spots were detected using UV light (UV Chamber) and spraying (50) H2SO4

All the above studies were carried out by using no special equipement these were done by

visual assessment

Identification of Pure Drug

The thin layer chromatography (TLC) method is used to identification of isolated compound

to standard compound or marker in which the Rf value was noted

Solubility studies

A solubility study was carried out to find out the solubility of drug in different solvents

According to this method the pure drug was added to the solvent medium and shaken for 2

hr The saturation was confirmed by observation of presence of undissolved material After

filtration of the slurry sample was analyzed using UV Visible spectrophotometer at 252 - 255

nm

Determination of pH

The pH meter was calibrated with buffered solution at 40 70 and 92 before starting pH

determination The glass electrode of the pH meter was immersed into the 50 ml beaker

containing 50 g gel and pH was noted

Homogeneacity

Homogeneacity was checked by visual inspection

Spreadability

The Spreadability of the formulation was determined by an apparatus suggested by muttimer

et al which was suitably modified in the laboratory and used for the study It consists of a

wooden block which was provided by a pulley at one end A rectangular ground glass plate

was fixed on this block An excess of gel (about 1 g) under the study was placed on this

ground plate The gel was then sandwiched between this plate and another glass plate having

the dimension of fixed ground plate and provided with the hook A 1 kg weight was placed

on the top of two plates for 5 minutes to expel air and to provide a uniform film of the gel

between the plates Excess of gel was scrapped off from the edges The top plate was then

subjected to pull of 10g with the help of string attached to the hook and the time (in second)

required by the top plate to cover a distance of 5 cm was noted

Carrageenan induced rat paw edema model volume was used to assess the anti-inflammatory

activity of developed herbal carbopol gel Left hind paws of each Rat were just marked

beyond the tibiotarsal junction so that every time the paw is dipped up to the fixed mark to

ensure constant paw volume The rats (180ndash200g) were randomly divided into 3 groups of 3

rats each Group A normal received normal saline only Edema was induced in the remaining

groups B-CGroup B (toxic control) received carrageenan only without the drug The C

received an application of herbal gel (1g) andor treatment plantar injection of 01 mL of a

1 carageenan wv freshly prepare carageenan in normal saline was given into the left hind

paw of each rat After One hour the gel was applied to the left hind paw of each rat of treated

group Measurements of the paw volume up to the ankle joint were performed before and at

different time intervals (1 2 3 4 5 6 8 10 12h) following the Carrageenan injection using

plethysmometer

Arthritis was induced in rats by subplannter injection of CFA(01 mlrat) in the right hind

paw Rats receiving CFA did not show any sign of acute toxicity Control animals were

injected with 09 saline On day 8 after adjuvant injection these rats were divided in

treatment groups (n = 6 ratsgroup) and injected daily with saline or agmatine 10 20 and 40

mgkg intraperitoneallyupto day 15 The animals were weighed daily The injections were

given daily in between 0900 and 1000 h and animals were subjected to measurement of

arthritis score[68]

as described below Thereafter they were shifted to their cages and the pre-

weighed food pellets were placed inside the cage hopper The food consumed by rats was

quantified by weighing leftover food in the hopper

Arthritis score

Evaluation of arthritis severity was performed by measuring the arthritis index of each

animal which was scored by grading eachpaw from 0 to 4 as described previously[68]

Grading was determined as follows

Table 23 Arthritis Score

Score Sign

0 No erythema or swelling

1 Slight erythema or swelling of one or more digits

2 Swelling of the entire paw

3 Erythema and swelling of the ankle

4 Ankylosis incapacity to bend the ankle

The severity score was the sum of the arthritis scores of the right hind limb maximum upto 4

On day 15 after adjuvant injection blood was withdrawn by retro-orbital method for

biochemical analysis

Paw Volume

The paw volumes of all animals were measured daily till day 15using a plethysmometer (VJ

instrument India) The change in pawvolume was measured as the difference between the

final and initial paw volumes

Stability studies[6970]

Stability studies of drug product being as a part of drug discovery and ends with the

commercial products to assess the drug and formulation stability stability study were carried

out for most satisfactory formulation was sealed in glass vial and kept at 30 plusmn2ordmC and 40

4 SUMMARY AND CONCLUSION

Boswellia serrata and Commiphora mukul is an anti-inflammatory and anti-arthritic drugs

used in the treatment of joint pain inflammation and arthritis The purpose of the topical and

dermatological dosage form is to conveniently deliver drug molecules across localized area of

skin Sustained release becomes important to supply the skin with a drug over a prolonged

period of time hence a dermatological delivery system such as gel was considered to be

1213

formulated Beside this gel form may reduce the frequency of dosing intervals and may

improve patient compliance The preliminary phytochemical screening of the extract was

done in view to know the various classes of chemical constituents i e secondary metabolites

From the results of the phytochemical screening of the extracts it was observed that the

fractional product of Commiphora mukul resin contained triterpenoids and sterols

Development of gel was done by using carbapol 934 which was analyzed with a smooth and

homogeneous appearance It was easily spreadable with an acceptable mechanical property

The observation of pH revealed that all the formulations were very near to skin pH make it

suitable for application on skin The results obtained from present work indicated that the

entire drug was uniformly distributed and there was no precipitation in formulation For the

incorporation of drugs five formulae for gel were tried During comparison of these

formulae it was observed that formula 3 showed the smooth texture optimum pH and good

spreadability Hence formula 3 was taken for further studies In vitro drug release of

Boswellic acid and Guggulsterones from gel was performed to study the release behavior of

drug from formulation From the observed results it was concluded that there is increase in

the drug release with respect to time From a patient compliance point of view spreadability

is a important for topical drug delivery system The gel was found to exhibit good percentage

spread by weight that would assure the skin application Anti-Inflammatory Anti-Arthritic

study and Arthritis scoring of the prepared gel formulation evident the Anti-Arthritic activity

of the prepared herbal gel formulation Temperature stability study was performed to evaluate

the separation as well as precipitation of the drug in the excipients mixture It was observed

that the formulation was stable at different temperatures (room temperature cool

temperature elevated temperature and at 75 RH) for 60 days

In the present work the attempt was made to formulate and evaluate a gel for anti-arthritic

activity using extracts of Boswellia serrata and Commiphora mukul The results showed that

the content of Gel components had significant effect on their physical rheological and in

vitro drug release characteristics

mass was exhausted with hot water the residue was collected on an ashless filter paper the

residue and the filter paper was incinerated until the ash was white or nearly so the filtrate

was added evaporated to dryness and ignited at a temperature not exceeding 450ordmC The

percentage of ash was calculated with reference to their air dried drug

Moisture content Water content is determined by removing the moisture and then by

measuring weight loss

Successive solvent extraction of resin[40]

The resin Commiphora mukul was taken and loaded in soxhlet extractor and extracted with

ethyl acetate about five times the weight of gum The temp is kept at 65-70degC The extracted

fluid is taken for solvent recovery The oleoresin (thick paste) obtained after solvent removal

was purified for enrichment of guggulsterones by solvent frication method 2 g sample of

guggul extract was taken in 250 mL round bottom flask 35 mL of 05 M alcoholic KOH was

added and reflux for 90 min on a water bath The content of flask was transferred to a

separator rinsed the flask with 50 mL lukewarm water Extracted while the liquid was warm

by shaking vigorously with three successive quantities of 50 mL petroleum ether (60-80deg)

Then combine the petroleum ether layers and wash with 20 mL water Evaporated the

petroleum ether and weighed the residue

Preliminary phytochemical screening of petroleum ether extract of resin of commiphora

mukul[41]

The plants may be considered as a biosynthetic laboratory for a multitude of compounds like

alkaloids triterpenoids glycosides volatile oils tannins saponins sugars etc that exert

physiological effects These compounds are responsible for therapeutic effects usually the

secondary metabolites The petroleum extracts of Commiphora mukul was subjected to

preliminary phytochemical screening for the detection of various plant constituents The

different phytochemical test are as follows

Tests for sterols alkaloids saponins tannins flavonoids proteins amino acids sugars

Thin layer chromatography study[42 43]

Active extracts those having promising antimicrobial and antifungal activitywere subjected to

thin layer chromatography to find out the number of compounds present in them The details

of the procedure were as follows

A Preparation of the plates

The adsorbent used for thin layer chromatography was silica gel G About 25 g of silica gel G

was taken in a glass mortar and about 35 ml of distilled water was added to it This mixture

was then allowed to swell for 15 minutes The mixture was stirred with glass rod until it

becomes homogeneous Then an additional 15 ml of distilled water was added to it with

stirring The suspension was then transferred to a 150 ml flask fitted with a plastic stopper

and was shaken vigorously for about 2 minutes This suspension was then spreaded

immediately on thin layer chromatographic plates with the help of a thin layer

chromatography (TLC) applicator (SUPERFIT) of Continental Instruments Bombay was

used

B Drying and storage of plates

The freshly coated plates were then air dried until the transparency of the layer had

disappeared The plates were then stacked in a drying rack and were activated in an oven for

30 minutes at 110C The activated plates were then kept ina dessicator till required for

further use

C Application of the sample

For applying test samples on TLC plates glass capillaries were used The spots were applied

with the help of a fine capillary keeping a minimum distance of 1 cm between the two

adjacent spots The spots of the samples were marked on the top of the plate to know their

identity

D Chromatographic chamber conditions of saturation and the development of TLC

plates

Chromatographic rectangular glass chamber (165 x 295 cm) was used in the experiments

To avoid insufficient chamber saturation and the undesirable edge effect a smooth sheet of

filter paper approximately of 15 x 40 cm size was placed in the chromatographic chamber in

a U shape and was allowed to be soaked in the developing solvent After being thus

moistened the paper was then pressed against the walls of the chamber so that it adhered to

the walls The chamber was allowed to saturate for 24 hours before use The experiments

were carried out at room temperature in diffused daylight

E Developing solvent system

A number of developing solvent systems were tried for each residue but the satisfactory

resolution was obtained in the solvent systems mentioned in table TLC results obtained in

these systems are as shown in Table 6

F Spraying equipment

Compressed air sprayer with a fine nozzle was used to detect the different constituents

present on TLC plates Air compressor was attached to a glass sprayer The sprayer was filled

with about 50 ml of the detection reagent and then used After each spray the sprayer was

washed separately with water chromic acid and distilled water and then with acetone

G Detection of The Spots

Spots were detected using UV light (UV Chamber) and spraying (50) H2SO4

The pH meter was calibrated with buffered solution at 40 70 and 92 before starting pH

determination The glass electrode of the pH meter was immersed into the 50 ml beaker

containing 50 g gel and pH was noted

Homogeneacity

Homogeneacity was checked by visual inspection

Spreadability

The Spreadability of the formulation was determined by an apparatus suggested by muttimer

et al which was suitably modified in the laboratory and used for the study It consists of a

wooden block which was provided by a pulley at one end A rectangular ground glass plate

was fixed on this block An excess of gel (about 1 g) under the study was placed on this

ground plate The gel was then sandwiched between this plate and another glass plate having

the dimension of fixed ground plate and provided with the hook A 1 kg weight was placed

on the top of two plates for 5 minutes to expel air and to provide a uniform film of the gel

between the plates Excess of gel was scrapped off from the edges The top plate was then

subjected to pull of 10g with the help of string attached to the hook and the time (in second)

required by the top plate to cover a distance of 5 cm was noted

In vivo anti-inflammatory activity[5152535455565758596061 62636465 6667]

Carrageenan induced rat paw edema model volume was used to assess the anti-inflammatory

activity of developed herbal carbopol gel Left hind paws of each Rat were just marked

beyond the tibiotarsal junction so that every time the paw is dipped up to the fixed mark to

ensure constant paw volume The rats (180ndash200g) were randomly divided into 3 groups of 3

rats each Group A normal received normal saline only Edema was induced in the remaining

groups B-CGroup B (toxic control) received carrageenan only without the drug The C

received an application of herbal gel (1g) andor treatment plantar injection of 01 mL of a

1 carageenan wv freshly prepare carageenan in normal saline was given into the left hind

paw of each rat After One hour the gel was applied to the left hind paw of each rat of treated

group Measurements of the paw volume up to the ankle joint were performed before and at

different time intervals (1 2 3 4 5 6 8 10 12h) following the Carrageenan injection using

plethysmometer

Percentage reduction calculated in edema was as follows

Inhibition = Edema (Control) minus Edema (Formulation Treated)

Edema (Control)

Arthritis Activity

Arthritis was induced in rats by subplannter injection of CFA(01 mlrat) in the right hind

paw Rats receiving CFA did not show any sign of acute toxicity Control animals were

injected with 09 saline On day 8 after adjuvant injection these rats were divided in

treatment groups (n = 6 ratsgroup) and injected daily with saline or agmatine 10 20 and 40

mgkg intraperitoneallyupto day 15 The animals were weighed daily The injections were

given daily in between 0900 and 1000 h and animals were subjected to measurement of

arthritis score[68]

as described below Thereafter they were shifted to their cages and the pre-

weighed food pellets were placed inside the cage hopper The food consumed by rats was

quantified by weighing leftover food in the hopper

Arthritis score

Evaluation of arthritis severity was performed by measuring the arthritis index of each

animal which was scored by grading eachpaw from 0 to 4 as described previously[68]

Grading was determined as follows

4 SUMMARY AND CONCLUSION

Boswellia serrata and Commiphora mukul is an anti-inflammatory and anti-arthritic drugs

used in the treatment of joint pain inflammation and arthritis The purpose of the topical and

dermatological dosage form is to conveniently deliver drug molecules across localized area of

skin Sustained release becomes important to supply the skin with a drug over a prolonged

period of time hence a dermatological delivery system such as gel was considered to be

formulated Beside this gel form may reduce the frequency of dosing intervals and may

improve patient compliance The preliminary phytochemical screening of the extract was

done in view to know the various classes of chemical constituents i e secondary metabolites

From the results of the phytochemical screening of the extracts it was observed that the

fractional product of Commiphora mukul resin contained triterpenoids and sterols

Development of gel was done by using carbapol 934 which was analyzed with a smooth and

homogeneous appearance It was easily spreadable with an acceptable mechanical property

The observation of pH revealed that all the formulations were very near to skin pH make it

suitable for application on skin The results obtained from present work indicated that the

entire drug was uniformly distributed and there was no precipitation in formulation For the

incorporation of drugs five formulae for gel were tried During comparison of these

formulae it was observed that formula 3 showed the smooth texture optimum pH and good

spreadability Hence formula 3 was taken for further studies In vitro drug release of

Boswellic acid and Guggulsterones from gel was performed to study the release behavior of

drug from formulation From the observed results it was concluded that there is increase in

the drug release with respect to time From a patient compliance point of view spreadability

is a important for topical drug delivery system The gel was found to exhibit good percentage

spread by weight that would assure the skin application Anti-Inflammatory Anti-Arthritic

study and Arthritis scoring of the prepared gel formulation evident the Anti-Arthritic activity

of the prepared herbal gel formulation Temperature stability study was performed to evaluate

the separation as well as precipitation of the drug in the excipients mixture It was observed

that the formulation was stable at different temperatures (room temperature cool

temperature elevated temperature and at 75 RH) for 60 days

In the present work the attempt was made to formulate and evaluate a gel for anti-arthritic

activity using extracts of Boswellia serrata and Commiphora mukul The results showed that

the content of Gel components had significant effect on their physical rheological and in

vitro drug release characteristics

mass was exhausted with hot water the residue was collected on an ashless filter paper the

residue and the filter paper was incinerated until the ash was white or nearly so the filtrate

was added evaporated to dryness and ignited at a temperature not exceeding 450ordmC The

percentage of ash was calculated with reference to their air dried drug

Moisture content Water content is determined by removing the moisture and then by

measuring weight loss

Successive solvent extraction of resin[40]

The resin Commiphora mukul was taken and loaded in soxhlet extractor and extracted with

ethyl acetate about five times the weight of gum The temp is kept at 65-70degC The extracted

fluid is taken for solvent recovery The oleoresin (thick paste) obtained after solvent removal

was purified for enrichment of guggulsterones by solvent frication method 2 g sample of

guggul extract was taken in 250 mL round bottom flask 35 mL of 05 M alcoholic KOH was

added and reflux for 90 min on a water bath The content of flask was transferred to a

separator rinsed the flask with 50 mL lukewarm water Extracted while the liquid was warm

by shaking vigorously with three successive quantities of 50 mL petroleum ether (60-80deg)

Then combine the petroleum ether layers and wash with 20 mL water Evaporated the

petroleum ether and weighed the residue

Preliminary phytochemical screening of petroleum ether extract of resin of commiphora

mukul[41]

The plants may be considered as a biosynthetic laboratory for a multitude of compounds like

alkaloids triterpenoids glycosides volatile oils tannins saponins sugars etc that exert

physiological effects These compounds are responsible for therapeutic effects usually the

secondary metabolites The petroleum extracts of Commiphora mukul was subjected to

preliminary phytochemical screening for the detection of various plant constituents The

different phytochemical test are as follows

Tests for sterols alkaloids saponins tannins flavonoids proteins amino acids sugars

Thin layer chromatography study[42 43]

Active extracts those having promising antimicrobial and antifungal activitywere subjected to

thin layer chromatography to find out the number of compounds present in them The details

of the procedure were as follows

A Preparation of the plates

The adsorbent used for thin layer chromatography was silica gel G About 25 g of silica gel G

was taken in a glass mortar and about 35 ml of distilled water was added to it This mixture

was then allowed to swell for 15 minutes The mixture was stirred with glass rod until it

becomes homogeneous Then an additional 15 ml of distilled water was added to it with

stirring The suspension was then transferred to a 150 ml flask fitted with a plastic stopper

and was shaken vigorously for about 2 minutes This suspension was then spreaded

immediately on thin layer chromatographic plates with the help of a thin layer

chromatography (TLC) applicator (SUPERFIT) of Continental Instruments Bombay was

used

B Drying and storage of plates

The freshly coated plates were then air dried until the transparency of the layer had

disappeared The plates were then stacked in a drying rack and were activated in an oven for

30 minutes at 110C The activated plates were then kept ina dessicator till required for

further use

C Application of the sample

For applying test samples on TLC plates glass capillaries were used The spots were applied

with the help of a fine capillary keeping a minimum distance of 1 cm between the two

adjacent spots The spots of the samples were marked on the top of the plate to know their

identity

D Chromatographic chamber conditions of saturation and the development of TLC

plates

Chromatographic rectangular glass chamber (165 x 295 cm) was used in the experiments

To avoid insufficient chamber saturation and the undesirable edge effect a smooth sheet of

filter paper approximately of 15 x 40 cm size was placed in the chromatographic chamber in

a U shape and was allowed to be soaked in the developing solvent After being thus

moistened the paper was then pressed against the walls of the chamber so that it adhered to

the walls The chamber was allowed to saturate for 24 hours before use The experiments

were carried out at room temperature in diffused daylight

E Developing solvent system

A number of developing solvent systems were tried for each residue but the satisfactory

resolution was obtained in the solvent systems mentioned in table TLC results obtained in

these systems are as shown in Table 6

F Spraying equipment

Compressed air sprayer with a fine nozzle was used to detect the different constituents

present on TLC plates Air compressor was attached to a glass sprayer The sprayer was filled

with about 50 ml of the detection reagent and then used After each spray the sprayer was

washed separately with water chromic acid and distilled water and then with acetone

G Detection of The Spots

Spots were detected using UV light (UV Chamber) and spraying (50) H2SO4

The Spreadability of the formulation was determined by an apparatus suggested by muttimer

et al which was suitably modified in the laboratory and used for the study It consists of a

wooden block which was provided by a pulley at one end A rectangular ground glass plate

was fixed on this block An excess of gel (about 1 g) under the study was placed on this

ground plate The gel was then sandwiched between this plate and another glass plate having

the dimension of fixed ground plate and provided with the hook A 1 kg weight was placed

on the top of two plates for 5 minutes to expel air and to provide a uniform film of the gel

between the plates Excess of gel was scrapped off from the edges The top plate was then

subjected to pull of 10g with the help of string attached to the hook and the time (in second)

required by the top plate to cover a distance of 5 cm was noted

In vivo anti-inflammatory activity[5152535455565758596061 62636465 6667]

Carrageenan induced rat paw edema model volume was used to assess the anti-inflammatory

activity of developed herbal carbopol gel Left hind paws of each Rat were just marked

beyond the tibiotarsal junction so that every time the paw is dipped up to the fixed mark to

ensure constant paw volume The rats (180ndash200g) were randomly divided into 3 groups of 3

rats each Group A normal received normal saline only Edema was induced in the remaining

groups B-CGroup B (toxic control) received carrageenan only without the drug The C

received an application of herbal gel (1g) andor treatment plantar injection of 01 mL of a

1 carageenan wv freshly prepare carageenan in normal saline was given into the left hind

paw of each rat After One hour the gel was applied to the left hind paw of each rat of treated

group Measurements of the paw volume up to the ankle joint were performed before and at

different time intervals (1 2 3 4 5 6 8 10 12h) following the Carrageenan injection using

plethysmometer

Percentage reduction calculated in edema was as follows

Inhibition = Edema (Control) minus Edema (Formulation Treated)

Edema (Control)

Arthritis Activity

Arthritis was induced in rats by subplannter injection of CFA(01 mlrat) in the right hind

paw Rats receiving CFA did not show any sign of acute toxicity Control animals were

injected with 09 saline On day 8 after adjuvant injection these rats were divided in

treatment groups (n = 6 ratsgroup) and injected daily with saline or agmatine 10 20 and 40

mgkg intraperitoneallyupto day 15 The animals were weighed daily The injections were

given daily in between 0900 and 1000 h and animals were subjected to measurement of

arthritis score[68]

as described below Thereafter they were shifted to their cages and the pre-

weighed food pellets were placed inside the cage hopper The food consumed by rats was

quantified by weighing leftover food in the hopper

Arthritis score

Evaluation of arthritis severity was performed by measuring the arthritis index of each

animal which was scored by grading eachpaw from 0 to 4 as described previously[68]

Grading was determined as follows

4 SUMMARY AND CONCLUSION

Boswellia serrata and Commiphora mukul is an anti-inflammatory and anti-arthritic drugs

used in the treatment of joint pain inflammation and arthritis The purpose of the topical and

dermatological dosage form is to conveniently deliver drug molecules across localized area of

skin Sustained release becomes important to supply the skin with a drug over a prolonged

period of time hence a dermatological delivery system such as gel was considered to be

formulated Beside this gel form may reduce the frequency of dosing intervals and may

improve patient compliance The preliminary phytochemical screening of the extract was

done in view to know the various classes of chemical constituents i e secondary metabolites

From the results of the phytochemical screening of the extracts it was observed that the

fractional product of Commiphora mukul resin contained triterpenoids and sterols

Development of gel was done by using carbapol 934 which was analyzed with a smooth and

homogeneous appearance It was easily spreadable with an acceptable mechanical property

The observation of pH revealed that all the formulations were very near to skin pH make it

suitable for application on skin The results obtained from present work indicated that the

entire drug was uniformly distributed and there was no precipitation in formulation For the

incorporation of drugs five formulae for gel were tried During comparison of these

formulae it was observed that formula 3 showed the smooth texture optimum pH and good

spreadability Hence formula 3 was taken for further studies In vitro drug release of

Boswellic acid and Guggulsterones from gel was performed to study the release behavior of

drug from formulation From the observed results it was concluded that there is increase in

the drug release with respect to time From a patient compliance point of view spreadability

is a important for topical drug delivery system The gel was found to exhibit good percentage

spread by weight that would assure the skin application Anti-Inflammatory Anti-Arthritic

study and Arthritis scoring of the prepared gel formulation evident the Anti-Arthritic activity

of the prepared herbal gel formulation Temperature stability study was performed to evaluate

the separation as well as precipitation of the drug in the excipients mixture It was observed

that the formulation was stable at different temperatures (room temperature cool

temperature elevated temperature and at 75 RH) for 60 days

In the present work the attempt was made to formulate and evaluate a gel for anti-arthritic

activity using extracts of Boswellia serrata and Commiphora mukul The results showed that

the content of Gel components had significant effect on their physical rheological and in

vitro drug release characteristics

mass was exhausted with hot water the residue was collected on an ashless filter paper the

residue and the filter paper was incinerated until the ash was white or nearly so the filtrate

was added evaporated to dryness and ignited at a temperature not exceeding 450ordmC The

percentage of ash was calculated with reference to their air dried drug

Moisture content Water content is determined by removing the moisture and then by

measuring weight loss

Successive solvent extraction of resin[40]

The resin Commiphora mukul was taken and loaded in soxhlet extractor and extracted with

ethyl acetate about five times the weight of gum The temp is kept at 65-70degC The extracted

fluid is taken for solvent recovery The oleoresin (thick paste) obtained after solvent removal

was purified for enrichment of guggulsterones by solvent frication method 2 g sample of

guggul extract was taken in 250 mL round bottom flask 35 mL of 05 M alcoholic KOH was

added and reflux for 90 min on a water bath The content of flask was transferred to a

separator rinsed the flask with 50 mL lukewarm water Extracted while the liquid was warm

by shaking vigorously with three successive quantities of 50 mL petroleum ether (60-80deg)

Then combine the petroleum ether layers and wash with 20 mL water Evaporated the

petroleum ether and weighed the residue

Preliminary phytochemical screening of petroleum ether extract of resin of commiphora

mukul[41]

The plants may be considered as a biosynthetic laboratory for a multitude of compounds like

alkaloids triterpenoids glycosides volatile oils tannins saponins sugars etc that exert

physiological effects These compounds are responsible for therapeutic effects usually the

secondary metabolites The petroleum extracts of Commiphora mukul was subjected to

preliminary phytochemical screening for the detection of various plant constituents The

different phytochemical test are as follows

Tests for sterols alkaloids saponins tannins flavonoids proteins amino acids sugars

Thin layer chromatography study[42 43]

Active extracts those having promising antimicrobial and antifungal activitywere subjected to

thin layer chromatography to find out the number of compounds present in them The details

of the procedure were as follows

A Preparation of the plates

The adsorbent used for thin layer chromatography was silica gel G About 25 g of silica gel G

was taken in a glass mortar and about 35 ml of distilled water was added to it This mixture

was then allowed to swell for 15 minutes The mixture was stirred with glass rod until it

becomes homogeneous Then an additional 15 ml of distilled water was added to it with

stirring The suspension was then transferred to a 150 ml flask fitted with a plastic stopper

and was shaken vigorously for about 2 minutes This suspension was then spreaded

immediately on thin layer chromatographic plates with the help of a thin layer

chromatography (TLC) applicator (SUPERFIT) of Continental Instruments Bombay was

used

B Drying and storage of plates

The freshly coated plates were then air dried until the transparency of the layer had

disappeared The plates were then stacked in a drying rack and were activated in an oven for

30 minutes at 110C The activated plates were then kept ina dessicator till required for

further use

C Application of the sample

For applying test samples on TLC plates glass capillaries were used The spots were applied

with the help of a fine capillary keeping a minimum distance of 1 cm between the two

adjacent spots The spots of the samples were marked on the top of the plate to know their

identity

D Chromatographic chamber conditions of saturation and the development of TLC

plates

Chromatographic rectangular glass chamber (165 x 295 cm) was used in the experiments

To avoid insufficient chamber saturation and the undesirable edge effect a smooth sheet of

filter paper approximately of 15 x 40 cm size was placed in the chromatographic chamber in

a U shape and was allowed to be soaked in the developing solvent After being thus

moistened the paper was then pressed against the walls of the chamber so that it adhered to

the walls The chamber was allowed to saturate for 24 hours before use The experiments

were carried out at room temperature in diffused daylight

E Developing solvent system

A number of developing solvent systems were tried for each residue but the satisfactory

resolution was obtained in the solvent systems mentioned in table TLC results obtained in

these systems are as shown in Table 6

F Spraying equipment

Compressed air sprayer with a fine nozzle was used to detect the different constituents

present on TLC plates Air compressor was attached to a glass sprayer The sprayer was filled

with about 50 ml of the detection reagent and then used After each spray the sprayer was

washed separately with water chromic acid and distilled water and then with acetone

G Detection of The Spots

Spots were detected using UV light (UV Chamber) and spraying (50) H2SO4

4 SUMMARY AND CONCLUSION

Boswellia serrata and Commiphora mukul is an anti-inflammatory and anti-arthritic drugs

used in the treatment of joint pain inflammation and arthritis The purpose of the topical and

dermatological dosage form is to conveniently deliver drug molecules across localized area of

skin Sustained release becomes important to supply the skin with a drug over a prolonged

period of time hence a dermatological delivery system such as gel was considered to be

formulated Beside this gel form may reduce the frequency of dosing intervals and may

improve patient compliance The preliminary phytochemical screening of the extract was

done in view to know the various classes of chemical constituents i e secondary metabolites

From the results of the phytochemical screening of the extracts it was observed that the

fractional product of Commiphora mukul resin contained triterpenoids and sterols

Development of gel was done by using carbapol 934 which was analyzed with a smooth and

homogeneous appearance It was easily spreadable with an acceptable mechanical property

The observation of pH revealed that all the formulations were very near to skin pH make it

suitable for application on skin The results obtained from present work indicated that the

entire drug was uniformly distributed and there was no precipitation in formulation For the

incorporation of drugs five formulae for gel were tried During comparison of these

formulae it was observed that formula 3 showed the smooth texture optimum pH and good

spreadability Hence formula 3 was taken for further studies In vitro drug release of

Boswellic acid and Guggulsterones from gel was performed to study the release behavior of

drug from formulation From the observed results it was concluded that there is increase in

the drug release with respect to time From a patient compliance point of view spreadability

is a important for topical drug delivery system The gel was found to exhibit good percentage

spread by weight that would assure the skin application Anti-Inflammatory Anti-Arthritic

study and Arthritis scoring of the prepared gel formulation evident the Anti-Arthritic activity

of the prepared herbal gel formulation Temperature stability study was performed to evaluate

the separation as well as precipitation of the drug in the excipients mixture It was observed

that the formulation was stable at different temperatures (room temperature cool

temperature elevated temperature and at 75 RH) for 60 days

In the present work the attempt was made to formulate and evaluate a gel for anti-arthritic

activity using extracts of Boswellia serrata and Commiphora mukul The results showed that

the content of Gel components had significant effect on their physical rheological and in

vitro drug release characteristics

Evaluation of raw material[39]

The evaluations of the crude drug were carried out by testing following parameters

Total ash About 2 g of the air dried crude drug was weighed accurately in a tared silica

crucible and incinerated at a temperature not exceeding 450ordmC until free from carbon It was

then cooled and weighed A carbon free ash was not obtained in this way Then the charred

Rizwan et al World Journal of Pharmaceutical Research

mass was exhausted with hot water the residue was collected on an ashless filter paper the

residue and the filter paper was incinerated until the ash was white or nearly so the filtrate

was added evaporated to dryness and ignited at a temperature not exceeding 450ordmC The

percentage of ash was calculated with reference to their air dried drug

Moisture content Water content is determined by removing the moisture and then by

measuring weight loss

Successive solvent extraction of resin[40]

The resin Commiphora mukul was taken and loaded in soxhlet extractor and extracted with

ethyl acetate about five times the weight of gum The temp is kept at 65-70degC The extracted

fluid is taken for solvent recovery The oleoresin (thick paste) obtained after solvent removal

was purified for enrichment of guggulsterones by solvent frication method 2 g sample of

guggul extract was taken in 250 mL round bottom flask 35 mL of 05 M alcoholic KOH was

added and reflux for 90 min on a water bath The content of flask was transferred to a

separator rinsed the flask with 50 mL lukewarm water Extracted while the liquid was warm

by shaking vigorously with three successive quantities of 50 mL petroleum ether (60-80deg)

Then combine the petroleum ether layers and wash with 20 mL water Evaporated the

petroleum ether and weighed the residue

Extraction Procedure

The collected resin was dried in a shade and powdered coarsely and was taken for soxhlet

extraction as shown in Figure 26

Preliminary phytochemical screening of petroleum ether extract of resin of commiphora

mukul[41]

The plants may be considered as a biosynthetic laboratory for a multitude of compounds like

alkaloids triterpenoids glycosides volatile oils tannins saponins sugars etc that exert

physiological effects These compounds are responsible for therapeutic effects usually the

secondary metabolites The petroleum extracts of Commiphora mukul was subjected to

preliminary phytochemical screening for the detection of various plant constituents The

different phytochemical test are as follows

Tests for sterols alkaloids saponins tannins flavonoids proteins amino acids sugars

Thin layer chromatography study[42 43]

Active extracts those having promising antimicrobial and antifungal activitywere subjected to

thin layer chromatography to find out the number of compounds present in them The details

of the procedure were as follows

A Preparation of the plates

The adsorbent used for thin layer chromatography was silica gel G About 25 g of silica gel G

was taken in a glass mortar and about 35 ml of distilled water was added to it This mixture

was then allowed to swell for 15 minutes The mixture was stirred with glass rod until it

becomes homogeneous Then an additional 15 ml of distilled water was added to it with

stirring The suspension was then transferred to a 150 ml flask fitted with a plastic stopper

and was shaken vigorously for about 2 minutes This suspension was then spreaded

immediately on thin layer chromatographic plates with the help of a thin layer

chromatography (TLC) applicator (SUPERFIT) of Continental Instruments Bombay was

used

B Drying and storage of plates

The freshly coated plates were then air dried until the transparency of the layer had

disappeared The plates were then stacked in a drying rack and were activated in an oven for

30 minutes at 110C The activated plates were then kept ina dessicator till required for

further use

C Application of the sample

For applying test samples on TLC plates glass capillaries were used The spots were applied

with the help of a fine capillary keeping a minimum distance of 1 cm between the two

adjacent spots The spots of the samples were marked on the top of the plate to know their

identity

D Chromatographic chamber conditions of saturation and the development of TLC

plates

Chromatographic rectangular glass chamber (165 x 295 cm) was used in the experiments

To avoid insufficient chamber saturation and the undesirable edge effect a smooth sheet of

filter paper approximately of 15 x 40 cm size was placed in the chromatographic chamber in

a U shape and was allowed to be soaked in the developing solvent After being thus

moistened the paper was then pressed against the walls of the chamber so that it adhered to

the walls The chamber was allowed to saturate for 24 hours before use The experiments

were carried out at room temperature in diffused daylight

E Developing solvent system

A number of developing solvent systems were tried for each residue but the satisfactory

resolution was obtained in the solvent systems mentioned in table TLC results obtained in

these systems are as shown in Table 6

F Spraying equipment

Compressed air sprayer with a fine nozzle was used to detect the different constituents

present on TLC plates Air compressor was attached to a glass sprayer The sprayer was filled

with about 50 ml of the detection reagent and then used After each spray the sprayer was

washed separately with water chromic acid and distilled water and then with acetone

G Detection of The Spots

Spots were detected using UV light (UV Chamber) and spraying (50) H2SO4

Evaluation of Gel[474849]

Determination of pH

The pH meter was calibrated with buffered solution at 40 70 and 92 before starting pH

determination The glass electrode of the pH meter was immersed into the 50 ml beaker

containing 50 g gel and pH was noted

Homogeneacity

Homogeneacity was checked by visual inspection

Spreadability

The Spreadability of the formulation was determined by an apparatus suggested by muttimer

et al which was suitably modified in the laboratory and used for the study It consists of a

wooden block which was provided by a pulley at one end A rectangular ground glass plate

was fixed on this block An excess of gel (about 1 g) under the study was placed on this

ground plate The gel was then sandwiched between this plate and another glass plate having

the dimension of fixed ground plate and provided with the hook A 1 kg weight was placed

on the top of two plates for 5 minutes to expel air and to provide a uniform film of the gel

between the plates Excess of gel was scrapped off from the edges The top plate was then

subjected to pull of 10g with the help of string attached to the hook and the time (in second)

required by the top plate to cover a distance of 5 cm was noted

Skin irritancy test

This test was performed on human volunteers Twenty volunteers were chosen for single

formulation and study was performed after taking their informed consent It was performed

by applying gel on an area of 2 square inch to the back of hand Then the examination for the

presence of lesion or irritation was done

Drug Content Studies Accurately weighed 1 g of gel was transferred into 100 ml

volumetric flask containing 20 ml of saline phosphate buffer (pH 68) and stirred for 30 min

followed by sonication The volume was made up to 100 ml with saline phosphate buffer (pH

68) After suitable dilution the absorbance was measured using Shimadzu 1700 UV Visible

spectrophotometer at 210 ndash 215 nm

Viscosity measurement Viscosity of the gel was determined by using Brookfield

viscometer Accurately weighed 100 g of gel was transferred to 100 ml glass beaker Spindle

no S64 was selected and it is immersed into the gel The viscometer was operated at various

rpm until the reading gets stabilized and reading was noted in centipoises It was noted from

the literature that the formulations after gelling should have a viscosity of 50 ndash 50000 cps

In vitro diffusion studies[50]

In-vitrodiffusion study was carried out in a Modified Franz diffusion cell using cellophane

membrane which is heated for 1hr in boiling water The membrane was tied to the donor

compartment and mounted on the reservoir compartment of Franz diffusion cell containing

21 ml of pH 68 phosphate buffer 1 g of Boswellia serrate and Commiphoramukulgel was

placed over the cellophane membrane of donor compartment Whole set was placed on the

magnetic stirrer The study was carried out at 37plusmn 05 ordmC and 100 rpm Samples were

withdrawn from the sampling port of reservoir compartment at regular intervals and

In vivo anti-inflammatory activity[5152535455565758596061 62636465 6667]

Carrageenan induced rat paw edema model volume was used to assess the anti-inflammatory

activity of developed herbal carbopol gel Left hind paws of each Rat were just marked

beyond the tibiotarsal junction so that every time the paw is dipped up to the fixed mark to

ensure constant paw volume The rats (180ndash200g) were randomly divided into 3 groups of 3

rats each Group A normal received normal saline only Edema was induced in the remaining

groups B-CGroup B (toxic control) received carrageenan only without the drug The C

received an application of herbal gel (1g) andor treatment plantar injection of 01 mL of a

1 carageenan wv freshly prepare carageenan in normal saline was given into the left hind

paw of each rat After One hour the gel was applied to the left hind paw of each rat of treated

group Measurements of the paw volume up to the ankle joint were performed before and at

different time intervals (1 2 3 4 5 6 8 10 12h) following the Carrageenan injection using

plethysmometer

Percentage reduction calculated in edema was as follows

Inhibition = Edema (Control) minus Edema (Formulation Treated)

Edema (Control)

Arthritis Activity

Arthritis was induced in rats by subplannter injection of CFA(01 mlrat) in the right hind

paw Rats receiving CFA did not show any sign of acute toxicity Control animals were

injected with 09 saline On day 8 after adjuvant injection these rats were divided in

treatment groups (n = 6 ratsgroup) and injected daily with saline or agmatine 10 20 and 40

mgkg intraperitoneallyupto day 15 The animals were weighed daily The injections were

given daily in between 0900 and 1000 h and animals were subjected to measurement of

arthritis score[68]

as described below Thereafter they were shifted to their cages and the pre-

weighed food pellets were placed inside the cage hopper The food consumed by rats was

quantified by weighing leftover food in the hopper

Arthritis score

Evaluation of arthritis severity was performed by measuring the arthritis index of each

animal which was scored by grading eachpaw from 0 to 4 as described previously[68]

Grading was determined as follows

The severity score was the sum of the arthritis scores of the right hind limb maximum upto 4

On day 15 after adjuvant injection blood was withdrawn by retro-orbital method for

biochemical analysis

Paw Volume

The paw volumes of all animals were measured daily till day 15using a plethysmometer (VJ

instrument India) The change in pawvolume was measured as the difference between the

final and initial paw volumes

improve patient compliance The preliminary phytochemical screening of the extract was

done in view to know the various classes of chemical constituents i e secondary metabolites

From the results of the phytochemical screening of the extracts it was observed that the

fractional product of Commiphora mukul resin contained triterpenoids and sterols

Development of gel was done by using carbapol 934 which was analyzed with a smooth and

homogeneous appearance It was easily spreadable with an acceptable mechanical property

The observation of pH revealed that all the formulations were very near to skin pH make it

suitable for application on skin The results obtained from present work indicated that the

entire drug was uniformly distributed and there was no precipitation in formulation For the

incorporation of drugs five formulae for gel were tried During comparison of these

formulae it was observed that formula 3 showed the smooth texture optimum pH and good

spreadability Hence formula 3 was taken for further studies In vitro drug release of

Boswellic acid and Guggulsterones from gel was performed to study the release behavior of

drug from formulation From the observed results it was concluded that there is increase in

the drug release with respect to time From a patient compliance point of view spreadability

is a important for topical drug delivery system The gel was found to exhibit good percentage

spread by weight that would assure the skin application Anti-Inflammatory Anti-Arthritic

study and Arthritis scoring of the prepared gel formulation evident the Anti-Arthritic activity

of the prepared herbal gel formulation Temperature stability study was performed to evaluate

the separation as well as precipitation of the drug in the excipients mixture It was observed

that the formulation was stable at different temperatures (room temperature cool

temperature elevated temperature and at 75 RH) for 60 days

In the present work the attempt was made to formulate and evaluate a gel for anti-arthritic

activity using extracts of Boswellia serrata and Commiphora mukul The results showed that

the content of Gel components had significant effect on their physical rheological and in

vitro drug release characteristics

mass was exhausted with hot water the residue was collected on an ashless filter paper the

residue and the filter paper was incinerated until the ash was white or nearly so the filtrate

was added evaporated to dryness and ignited at a temperature not exceeding 450ordmC The

percentage of ash was calculated with reference to their air dried drug

Moisture content Water content is determined by removing the moisture and then by

measuring weight loss

Successive solvent extraction of resin[40]

The resin Commiphora mukul was taken and loaded in soxhlet extractor and extracted with

ethyl acetate about five times the weight of gum The temp is kept at 65-70degC The extracted

fluid is taken for solvent recovery The oleoresin (thick paste) obtained after solvent removal

was purified for enrichment of guggulsterones by solvent frication method 2 g sample of

guggul extract was taken in 250 mL round bottom flask 35 mL of 05 M alcoholic KOH was

added and reflux for 90 min on a water bath The content of flask was transferred to a

separator rinsed the flask with 50 mL lukewarm water Extracted while the liquid was warm

by shaking vigorously with three successive quantities of 50 mL petroleum ether (60-80deg)

Then combine the petroleum ether layers and wash with 20 mL water Evaporated the

petroleum ether and weighed the residue

Extraction Procedure

The collected resin was dried in a shade and powdered coarsely and was taken for soxhlet

extraction as shown in Figure 26

Preliminary phytochemical screening of petroleum ether extract of resin of commiphora

mukul[41]

The plants may be considered as a biosynthetic laboratory for a multitude of compounds like

alkaloids triterpenoids glycosides volatile oils tannins saponins sugars etc that exert

physiological effects These compounds are responsible for therapeutic effects usually the

secondary metabolites The petroleum extracts of Commiphora mukul was subjected to

preliminary phytochemical screening for the detection of various plant constituents The

different phytochemical test are as follows

Tests for sterols alkaloids saponins tannins flavonoids proteins amino acids sugars

Thin layer chromatography study[42 43]

Active extracts those having promising antimicrobial and antifungal activitywere subjected to

thin layer chromatography to find out the number of compounds present in them The details

of the procedure were as follows

A Preparation of the plates

The adsorbent used for thin layer chromatography was silica gel G About 25 g of silica gel G

was taken in a glass mortar and about 35 ml of distilled water was added to it This mixture

was then allowed to swell for 15 minutes The mixture was stirred with glass rod until it

becomes homogeneous Then an additional 15 ml of distilled water was added to it with

stirring The suspension was then transferred to a 150 ml flask fitted with a plastic stopper

and was shaken vigorously for about 2 minutes This suspension was then spreaded

immediately on thin layer chromatographic plates with the help of a thin layer

chromatography (TLC) applicator (SUPERFIT) of Continental Instruments Bombay was

used

B Drying and storage of plates

The freshly coated plates were then air dried until the transparency of the layer had

disappeared The plates were then stacked in a drying rack and were activated in an oven for

30 minutes at 110C The activated plates were then kept ina dessicator till required for

further use

C Application of the sample

For applying test samples on TLC plates glass capillaries were used The spots were applied

with the help of a fine capillary keeping a minimum distance of 1 cm between the two

adjacent spots The spots of the samples were marked on the top of the plate to know their

identity

D Chromatographic chamber conditions of saturation and the development of TLC

plates

Chromatographic rectangular glass chamber (165 x 295 cm) was used in the experiments

To avoid insufficient chamber saturation and the undesirable edge effect a smooth sheet of

filter paper approximately of 15 x 40 cm size was placed in the chromatographic chamber in

a U shape and was allowed to be soaked in the developing solvent After being thus

moistened the paper was then pressed against the walls of the chamber so that it adhered to

the walls The chamber was allowed to saturate for 24 hours before use The experiments

were carried out at room temperature in diffused daylight

E Developing solvent system

A number of developing solvent systems were tried for each residue but the satisfactory

resolution was obtained in the solvent systems mentioned in table TLC results obtained in

these systems are as shown in Table 6

F Spraying equipment

Compressed air sprayer with a fine nozzle was used to detect the different constituents

present on TLC plates Air compressor was attached to a glass sprayer The sprayer was filled

with about 50 ml of the detection reagent and then used After each spray the sprayer was

washed separately with water chromic acid and distilled water and then with acetone

G Detection of The Spots

Spots were detected using UV light (UV Chamber) and spraying (50) H2SO4

Preformulation studies[44 45 46]

It mainly involved two parameters organoleptic and physicochemical properties of the API

used This was mainly done to check the purity of the drug and any deviation could also help

to know if there is any deterioration involved

Organoleptic Properties

Appearance

Colour

Odour

Melting point

All the above studies were carried out by using no special equipement these were done by

visual assessment

Identification of Pure Drug

The thin layer chromatography (TLC) method is used to identification of isolated compound

to standard compound or marker in which the Rf value was noted

Solubility studies

A solubility study was carried out to find out the solubility of drug in different solvents

According to this method the pure drug was added to the solvent medium and shaken for 2

hr The saturation was confirmed by observation of presence of undissolved material After

filtration of the slurry sample was analyzed using UV Visible spectrophotometer at 252 - 255

nm

Formulation development[444546]

Formulation of Gel Carbopol 934 was dispersed in distilled water by stirring at 800 rpm

for 30min in another beaker extract of boswelliaserrata and extract of commiphora mukul

was dissolved in iso-propyl alcohol then polyethylene glycol 400 ethanol and methyl

paraben added slowly then added these solution to gel base and stired it and mixture was

Evaluation of Gel[474849]

Determination of pH

The pH meter was calibrated with buffered solution at 40 70 and 92 before starting pH

determination The glass electrode of the pH meter was immersed into the 50 ml beaker

containing 50 g gel and pH was noted

Homogeneacity

Homogeneacity was checked by visual inspection

Spreadability

The Spreadability of the formulation was determined by an apparatus suggested by muttimer

et al which was suitably modified in the laboratory and used for the study It consists of a

wooden block which was provided by a pulley at one end A rectangular ground glass plate

was fixed on this block An excess of gel (about 1 g) under the study was placed on this

ground plate The gel was then sandwiched between this plate and another glass plate having

the dimension of fixed ground plate and provided with the hook A 1 kg weight was placed

on the top of two plates for 5 minutes to expel air and to provide a uniform film of the gel

between the plates Excess of gel was scrapped off from the edges The top plate was then

subjected to pull of 10g with the help of string attached to the hook and the time (in second)

required by the top plate to cover a distance of 5 cm was noted

Skin irritancy test

This test was performed on human volunteers Twenty volunteers were chosen for single

formulation and study was performed after taking their informed consent It was performed

by applying gel on an area of 2 square inch to the back of hand Then the examination for the

presence of lesion or irritation was done

Drug Content Studies Accurately weighed 1 g of gel was transferred into 100 ml

volumetric flask containing 20 ml of saline phosphate buffer (pH 68) and stirred for 30 min

followed by sonication The volume was made up to 100 ml with saline phosphate buffer (pH

68) After suitable dilution the absorbance was measured using Shimadzu 1700 UV Visible

spectrophotometer at 210 ndash 215 nm

Viscosity measurement Viscosity of the gel was determined by using Brookfield

viscometer Accurately weighed 100 g of gel was transferred to 100 ml glass beaker Spindle

no S64 was selected and it is immersed into the gel The viscometer was operated at various

rpm until the reading gets stabilized and reading was noted in centipoises It was noted from

the literature that the formulations after gelling should have a viscosity of 50 ndash 50000 cps

In vitro diffusion studies[50]

In-vitrodiffusion study was carried out in a Modified Franz diffusion cell using cellophane

membrane which is heated for 1hr in boiling water The membrane was tied to the donor

compartment and mounted on the reservoir compartment of Franz diffusion cell containing

21 ml of pH 68 phosphate buffer 1 g of Boswellia serrate and Commiphoramukulgel was

placed over the cellophane membrane of donor compartment Whole set was placed on the

magnetic stirrer The study was carried out at 37plusmn 05 ordmC and 100 rpm Samples were

withdrawn from the sampling port of reservoir compartment at regular intervals and

absorbance was measured using Shimadzu 2300 UV visible spectrophotometer at 210 ndash 215

In vivo anti-inflammatory activity[5152535455565758596061 62636465 6667]

Carrageenan induced rat paw edema model volume was used to assess the anti-inflammatory

activity of developed herbal carbopol gel Left hind paws of each Rat were just marked

beyond the tibiotarsal junction so that every time the paw is dipped up to the fixed mark to

ensure constant paw volume The rats (180ndash200g) were randomly divided into 3 groups of 3

rats each Group A normal received normal saline only Edema was induced in the remaining

groups B-CGroup B (toxic control) received carrageenan only without the drug The C

received an application of herbal gel (1g) andor treatment plantar injection of 01 mL of a

1 carageenan wv freshly prepare carageenan in normal saline was given into the left hind

paw of each rat After One hour the gel was applied to the left hind paw of each rat of treated

group Measurements of the paw volume up to the ankle joint were performed before and at

different time intervals (1 2 3 4 5 6 8 10 12h) following the Carrageenan injection using

plethysmometer

Percentage reduction calculated in edema was as follows

Inhibition = Edema (Control) minus Edema (Formulation Treated)

Edema (Control)

Arthritis Activity

Arthritis was induced in rats by subplannter injection of CFA(01 mlrat) in the right hind

paw Rats receiving CFA did not show any sign of acute toxicity Control animals were

injected with 09 saline On day 8 after adjuvant injection these rats were divided in

treatment groups (n = 6 ratsgroup) and injected daily with saline or agmatine 10 20 and 40

mgkg intraperitoneallyupto day 15 The animals were weighed daily The injections were

given daily in between 0900 and 1000 h and animals were subjected to measurement of

arthritis score[68]

as described below Thereafter they were shifted to their cages and the pre-

weighed food pellets were placed inside the cage hopper The food consumed by rats was

quantified by weighing leftover food in the hopper

Arthritis score

Evaluation of arthritis severity was performed by measuring the arthritis index of each

animal which was scored by grading eachpaw from 0 to 4 as described previously[68]

Grading was determined as follows

Rizwan et al World Journal of Pharmaceutical Research

wwwwjprnet Vol 9 Issue 1 2020

Score Sign

0 No erythema or swelling

1 Slight erythema or swelling of one or more digits

2 Swelling of the entire paw

3 Erythema and swelling of the ankle

4 Ankylosis incapacity to bend the ankle

The severity score was the sum of the arthritis scores of the right hind limb maximum upto 4

On day 15 after adjuvant injection blood was withdrawn by retro-orbital method for

biochemical analysis

Paw Volume

The paw volumes of all animals were measured daily till day 15using a plethysmometer (VJ

instrument India) The change in pawvolume was measured as the difference between the

final and initial paw volumes

4 SUMMARY AND CONCLUSION

Boswellia serrata and Commiphora mukul is an anti-inflammatory and anti-arthritic drugs

used in the treatment of joint pain inflammation and arthritis The purpose of the topical and

dermatological dosage form is to conveniently deliver drug molecules across localized area of

skin Sustained release becomes important to supply the skin with a drug over a prolonged

period of time hence a dermatological delivery system such as gel was considered to be

1213

formulated Beside this gel form may reduce the frequency of dosing intervals and may

improve patient compliance The preliminary phytochemical screening of the extract was

done in view to know the various classes of chemical constituents i e secondary metabolites

From the results of the phytochemical screening of the extracts it was observed that the

fractional product of Commiphora mukul resin contained triterpenoids and sterols

Development of gel was done by using carbapol 934 which was analyzed with a smooth and

homogeneous appearance It was easily spreadable with an acceptable mechanical property

The observation of pH revealed that all the formulations were very near to skin pH make it

suitable for application on skin The results obtained from present work indicated that the

entire drug was uniformly distributed and there was no precipitation in formulation For the

incorporation of drugs five formulae for gel were tried During comparison of these

formulae it was observed that formula 3 showed the smooth texture optimum pH and good

spreadability Hence formula 3 was taken for further studies In vitro drug release of

Boswellic acid and Guggulsterones from gel was performed to study the release behavior of

drug from formulation From the observed results it was concluded that there is increase in

the drug release with respect to time From a patient compliance point of view spreadability

is a important for topical drug delivery system The gel was found to exhibit good percentage

spread by weight that would assure the skin application Anti-Inflammatory Anti-Arthritic

study and Arthritis scoring of the prepared gel formulation evident the Anti-Arthritic activity

of the prepared herbal gel formulation Temperature stability study was performed to evaluate

the separation as well as precipitation of the drug in the excipients mixture It was observed

that the formulation was stable at different temperatures (room temperature cool

temperature elevated temperature and at 75 RH) for 60 days

In the present work the attempt was made to formulate and evaluate a gel for anti-arthritic

activity using extracts of Boswellia serrata and Commiphora mukul The results showed that

the content of Gel components had significant effect on their physical rheological and in

vitro drug release characteristics

Preliminary phytochemical screening of petroleum ether extract of resin of commiphora

mukul[41]

The plants may be considered as a biosynthetic laboratory for a multitude of compounds like

alkaloids triterpenoids glycosides volatile oils tannins saponins sugars etc that exert

physiological effects These compounds are responsible for therapeutic effects usually the

secondary metabolites The petroleum extracts of Commiphora mukul was subjected to

preliminary phytochemical screening for the detection of various plant constituents The

different phytochemical test are as follows

Tests for sterols alkaloids saponins tannins flavonoids proteins amino acids sugars

Thin layer chromatography study[42 43]

Active extracts those having promising antimicrobial and antifungal activitywere subjected to

thin layer chromatography to find out the number of compounds present in them The details

of the procedure were as follows

A Preparation of the plates

The adsorbent used for thin layer chromatography was silica gel G About 25 g of silica gel G

was taken in a glass mortar and about 35 ml of distilled water was added to it This mixture

was then allowed to swell for 15 minutes The mixture was stirred with glass rod until it

becomes homogeneous Then an additional 15 ml of distilled water was added to it with

stirring The suspension was then transferred to a 150 ml flask fitted with a plastic stopper

and was shaken vigorously for about 2 minutes This suspension was then spreaded

immediately on thin layer chromatographic plates with the help of a thin layer

chromatography (TLC) applicator (SUPERFIT) of Continental Instruments Bombay was

used

B Drying and storage of plates

The freshly coated plates were then air dried until the transparency of the layer had

disappeared The plates were then stacked in a drying rack and were activated in an oven for

30 minutes at 110C The activated plates were then kept ina dessicator till required for

further use

C Application of the sample

For applying test samples on TLC plates glass capillaries were used The spots were applied

with the help of a fine capillary keeping a minimum distance of 1 cm between the two

adjacent spots The spots of the samples were marked on the top of the plate to know their

identity

D Chromatographic chamber conditions of saturation and the development of TLC

plates

Chromatographic rectangular glass chamber (165 x 295 cm) was used in the experiments

To avoid insufficient chamber saturation and the undesirable edge effect a smooth sheet of

filter paper approximately of 15 x 40 cm size was placed in the chromatographic chamber in

a U shape and was allowed to be soaked in the developing solvent After being thus

moistened the paper was then pressed against the walls of the chamber so that it adhered to

the walls The chamber was allowed to saturate for 24 hours before use The experiments

were carried out at room temperature in diffused daylight

E Developing solvent system

A number of developing solvent systems were tried for each residue but the satisfactory

resolution was obtained in the solvent systems mentioned in table TLC results obtained in

these systems are as shown in Table 6

F Spraying equipment

Compressed air sprayer with a fine nozzle was used to detect the different constituents

present on TLC plates Air compressor was attached to a glass sprayer The sprayer was filled

with about 50 ml of the detection reagent and then used After each spray the sprayer was

washed separately with water chromic acid and distilled water and then with acetone

G Detection of The Spots

Spots were detected using UV light (UV Chamber) and spraying (50) H2SO4

Assay of Boswellia Serrata

A) Total acids Weighed accurately about 02g of the sample and dissolved in 30 mL of

methanol by keeping in a sonicator for 5-10 min Titrated against 001N NaoH using

phenolphthalein as a indicator Performed blank titration using methanol

Calculation For Total Acids

B) Mineral acidity Weighed about 02g of sample and added 100ml of water Heatedthe

sample at 70ordmC for 15 minutes in a water bath Filtered and collected the filterate

Recorded the pH of filterate Took care to wash the residue on the funnel and collected

the washings and filterate in the conical flask and titrated it against 001N NaoH using

phenolphthalein as a indicator Performed blank titration using water

Melting point

All the above studies were carried out by using no special equipement these were done by

visual assessment

Identification of Pure Drug

The thin layer chromatography (TLC) method is used to identification of isolated compound

to standard compound or marker in which the Rf value was noted

Solubility studies

A solubility study was carried out to find out the solubility of drug in different solvents

According to this method the pure drug was added to the solvent medium and shaken for 2

hr The saturation was confirmed by observation of presence of undissolved material After

filtration of the slurry sample was analyzed using UV Visible spectrophotometer at 252 - 255

nm

Formulation development[444546]

Evaluation of Gel[474849]

Determination of pH

The pH meter was calibrated with buffered solution at 40 70 and 92 before starting pH

determination The glass electrode of the pH meter was immersed into the 50 ml beaker

containing 50 g gel and pH was noted

Homogeneacity

Homogeneacity was checked by visual inspection

Spreadability

The Spreadability of the formulation was determined by an apparatus suggested by muttimer

et al which was suitably modified in the laboratory and used for the study It consists of a

wooden block which was provided by a pulley at one end A rectangular ground glass plate

was fixed on this block An excess of gel (about 1 g) under the study was placed on this

ground plate The gel was then sandwiched between this plate and another glass plate having

the dimension of fixed ground plate and provided with the hook A 1 kg weight was placed

on the top of two plates for 5 minutes to expel air and to provide a uniform film of the gel

between the plates Excess of gel was scrapped off from the edges The top plate was then

subjected to pull of 10g with the help of string attached to the hook and the time (in second)

required by the top plate to cover a distance of 5 cm was noted

Skin irritancy test

This test was performed on human volunteers Twenty volunteers were chosen for single

formulation and study was performed after taking their informed consent It was performed

by applying gel on an area of 2 square inch to the back of hand Then the examination for the

presence of lesion or irritation was done

Drug Content Studies Accurately weighed 1 g of gel was transferred into 100 ml

volumetric flask containing 20 ml of saline phosphate buffer (pH 68) and stirred for 30 min

followed by sonication The volume was made up to 100 ml with saline phosphate buffer (pH

68) After suitable dilution the absorbance was measured using Shimadzu 1700 UV Visible

spectrophotometer at 210 ndash 215 nm

Viscosity measurement Viscosity of the gel was determined by using Brookfield

viscometer Accurately weighed 100 g of gel was transferred to 100 ml glass beaker Spindle

no S64 was selected and it is immersed into the gel The viscometer was operated at various

rpm until the reading gets stabilized and reading was noted in centipoises It was noted from

the literature that the formulations after gelling should have a viscosity of 50 ndash 50000 cps

In vitro diffusion studies[50]

In-vitrodiffusion study was carried out in a Modified Franz diffusion cell using cellophane

membrane which is heated for 1hr in boiling water The membrane was tied to the donor

compartment and mounted on the reservoir compartment of Franz diffusion cell containing

21 ml of pH 68 phosphate buffer 1 g of Boswellia serrate and Commiphoramukulgel was

placed over the cellophane membrane of donor compartment Whole set was placed on the

magnetic stirrer The study was carried out at 37plusmn 05 ordmC and 100 rpm Samples were

withdrawn from the sampling port of reservoir compartment at regular intervals and

absorbance was measured using Shimadzu 2300 UV visible spectrophotometer at 210 ndash 215

In vivo anti-inflammatory activity[5152535455565758596061 62636465 6667]

Carrageenan induced rat paw edema model volume was used to assess the anti-inflammatory

activity of developed herbal carbopol gel Left hind paws of each Rat were just marked

beyond the tibiotarsal junction so that every time the paw is dipped up to the fixed mark to

ensure constant paw volume The rats (180ndash200g) were randomly divided into 3 groups of 3

rats each Group A normal received normal saline only Edema was induced in the remaining

groups B-CGroup B (toxic control) received carrageenan only without the drug The C

received an application of herbal gel (1g) andor treatment plantar injection of 01 mL of a

1 carageenan wv freshly prepare carageenan in normal saline was given into the left hind

paw of each rat After One hour the gel was applied to the left hind paw of each rat of treated

group Measurements of the paw volume up to the ankle joint were performed before and at

different time intervals (1 2 3 4 5 6 8 10 12h) following the Carrageenan injection using

plethysmometer

Percentage reduction calculated in edema was as follows

Inhibition = Edema (Control) minus Edema (Formulation Treated)

Edema (Control)

Arthritis Activity

Arthritis was induced in rats by subplannter injection of CFA(01 mlrat) in the right hind

paw Rats receiving CFA did not show any sign of acute toxicity Control animals were

injected with 09 saline On day 8 after adjuvant injection these rats were divided in

treatment groups (n = 6 ratsgroup) and injected daily with saline or agmatine 10 20 and 40

mgkg intraperitoneallyupto day 15 The animals were weighed daily The injections were

given daily in between 0900 and 1000 h and animals were subjected to measurement of

arthritis score[68]

as described below Thereafter they were shifted to their cages and the pre-

weighed food pellets were placed inside the cage hopper The food consumed by rats was

quantified by weighing leftover food in the hopper

Arthritis score

Evaluation of arthritis severity was performed by measuring the arthritis index of each

animal which was scored by grading eachpaw from 0 to 4 as described previously[68]

Grading was determined as follows

Rizwan et al World Journal of Pharmaceutical Research

4 SUMMARY AND CONCLUSION

Boswellia serrata and Commiphora mukul is an anti-inflammatory and anti-arthritic drugs

used in the treatment of joint pain inflammation and arthritis The purpose of the topical and

dermatological dosage form is to conveniently deliver drug molecules across localized area of

skin Sustained release becomes important to supply the skin with a drug over a prolonged

period of time hence a dermatological delivery system such as gel was considered to be

formulated Beside this gel form may reduce the frequency of dosing intervals and may

improve patient compliance The preliminary phytochemical screening of the extract was

done in view to know the various classes of chemical constituents i e secondary metabolites

From the results of the phytochemical screening of the extracts it was observed that the

fractional product of Commiphora mukul resin contained triterpenoids and sterols

Development of gel was done by using carbapol 934 which was analyzed with a smooth and

homogeneous appearance It was easily spreadable with an acceptable mechanical property

The observation of pH revealed that all the formulations were very near to skin pH make it

suitable for application on skin The results obtained from present work indicated that the

entire drug was uniformly distributed and there was no precipitation in formulation For the

incorporation of drugs five formulae for gel were tried During comparison of these

formulae it was observed that formula 3 showed the smooth texture optimum pH and good

spreadability Hence formula 3 was taken for further studies In vitro drug release of

Boswellic acid and Guggulsterones from gel was performed to study the release behavior of

drug from formulation From the observed results it was concluded that there is increase in

the drug release with respect to time From a patient compliance point of view spreadability

is a important for topical drug delivery system The gel was found to exhibit good percentage

spread by weight that would assure the skin application Anti-Inflammatory Anti-Arthritic

study and Arthritis scoring of the prepared gel formulation evident the Anti-Arthritic activity

of the prepared herbal gel formulation Temperature stability study was performed to evaluate

the separation as well as precipitation of the drug in the excipients mixture It was observed

that the formulation was stable at different temperatures (room temperature cool

temperature elevated temperature and at 75 RH) for 60 days

In the present work the attempt was made to formulate and evaluate a gel for anti-arthritic

activity using extracts of Boswellia serrata and Commiphora mukul The results showed that

the content of Gel components had significant effect on their physical rheological and in

vitro drug release characteristics

D Chromatographic chamber conditions of saturation and the development of TLC

plates

Chromatographic rectangular glass chamber (165 x 295 cm) was used in the experiments

To avoid insufficient chamber saturation and the undesirable edge effect a smooth sheet of

filter paper approximately of 15 x 40 cm size was placed in the chromatographic chamber in

a U shape and was allowed to be soaked in the developing solvent After being thus

moistened the paper was then pressed against the walls of the chamber so that it adhered to

the walls The chamber was allowed to saturate for 24 hours before use The experiments

were carried out at room temperature in diffused daylight

E Developing solvent system

A number of developing solvent systems were tried for each residue but the satisfactory

resolution was obtained in the solvent systems mentioned in table TLC results obtained in

these systems are as shown in Table 6

F Spraying equipment

Compressed air sprayer with a fine nozzle was used to detect the different constituents

present on TLC plates Air compressor was attached to a glass sprayer The sprayer was filled

with about 50 ml of the detection reagent and then used After each spray the sprayer was

washed separately with water chromic acid and distilled water and then with acetone

G Detection of The Spots

Spots were detected using UV light (UV Chamber) and spraying (50) H2SO4

Assay of Boswellia Serrata

A) Total acids Weighed accurately about 02g of the sample and dissolved in 30 mL of

methanol by keeping in a sonicator for 5-10 min Titrated against 001N NaoH using

phenolphthalein as a indicator Performed blank titration using methanol

Calculation For Total Acids

B) Mineral acidity Weighed about 02g of sample and added 100ml of water Heatedthe

sample at 70ordmC for 15 minutes in a water bath Filtered and collected the filterate

Recorded the pH of filterate Took care to wash the residue on the funnel and collected

the washings and filterate in the conical flask and titrated it against 001N NaoH using

phenolphthalein as a indicator Performed blank titration using water

Preformulation studies[44 45 46]

It mainly involved two parameters organoleptic and physicochemical properties of the API

used This was mainly done to check the purity of the drug and any deviation could also help

to know if there is any deterioration involved

Organoleptic Properties

Appearance

Colour

Odour

Melting point

All the above studies were carried out by using no special equipement these were done by

visual assessment

Identification of Pure Drug

The thin layer chromatography (TLC) method is used to identification of isolated compound

to standard compound or marker in which the Rf value was noted

Solubility studies

A solubility study was carried out to find out the solubility of drug in different solvents

According to this method the pure drug was added to the solvent medium and shaken for 2

hr The saturation was confirmed by observation of presence of undissolved material After

filtration of the slurry sample was analyzed using UV Visible spectrophotometer at 252 - 255

nm

Formulation development[444546]

Formulation of Gel Carbopol 934 was dispersed in distilled water by stirring at 800 rpm

for 30min in another beaker extract of boswelliaserrata and extract of commiphora mukul

was dissolved in iso-propyl alcohol then polyethylene glycol 400 ethanol and methyl

paraben added slowly then added these solution to gel base and stired it and mixture was

Evaluation of Gel[474849]

Determination of pH

The pH meter was calibrated with buffered solution at 40 70 and 92 before starting pH

determination The glass electrode of the pH meter was immersed into the 50 ml beaker

containing 50 g gel and pH was noted

Homogeneacity

Homogeneacity was checked by visual inspection

Spreadability

The Spreadability of the formulation was determined by an apparatus suggested by muttimer

et al which was suitably modified in the laboratory and used for the study It consists of a

wooden block which was provided by a pulley at one end A rectangular ground glass plate

was fixed on this block An excess of gel (about 1 g) under the study was placed on this

ground plate The gel was then sandwiched between this plate and another glass plate having

the dimension of fixed ground plate and provided with the hook A 1 kg weight was placed

on the top of two plates for 5 minutes to expel air and to provide a uniform film of the gel

between the plates Excess of gel was scrapped off from the edges The top plate was then

subjected to pull of 10g with the help of string attached to the hook and the time (in second)

required by the top plate to cover a distance of 5 cm was noted

Skin irritancy test

This test was performed on human volunteers Twenty volunteers were chosen for single

formulation and study was performed after taking their informed consent It was performed

by applying gel on an area of 2 square inch to the back of hand Then the examination for the

presence of lesion or irritation was done

Drug Content Studies Accurately weighed 1 g of gel was transferred into 100 ml

volumetric flask containing 20 ml of saline phosphate buffer (pH 68) and stirred for 30 min

followed by sonication The volume was made up to 100 ml with saline phosphate buffer (pH

68) After suitable dilution the absorbance was measured using Shimadzu 1700 UV Visible

spectrophotometer at 210 ndash 215 nm

Viscosity measurement Viscosity of the gel was determined by using Brookfield

viscometer Accurately weighed 100 g of gel was transferred to 100 ml glass beaker Spindle

no S64 was selected and it is immersed into the gel The viscometer was operated at various

rpm until the reading gets stabilized and reading was noted in centipoises It was noted from

the literature that the formulations after gelling should have a viscosity of 50 ndash 50000 cps

In vitro diffusion studies[50]

In-vitrodiffusion study was carried out in a Modified Franz diffusion cell using cellophane

membrane which is heated for 1hr in boiling water The membrane was tied to the donor

compartment and mounted on the reservoir compartment of Franz diffusion cell containing

21 ml of pH 68 phosphate buffer 1 g of Boswellia serrate and Commiphoramukulgel was

placed over the cellophane membrane of donor compartment Whole set was placed on the

magnetic stirrer The study was carried out at 37plusmn 05 ordmC and 100 rpm Samples were

withdrawn from the sampling port of reservoir compartment at regular intervals and

absorbance was measured using Shimadzu 2300 UV visible spectrophotometer at 210 ndash 215

In vivo anti-inflammatory activity[5152535455565758596061 62636465 6667]

Carrageenan induced rat paw edema model volume was used to assess the anti-inflammatory

activity of developed herbal carbopol gel Left hind paws of each Rat were just marked

beyond the tibiotarsal junction so that every time the paw is dipped up to the fixed mark to

ensure constant paw volume The rats (180ndash200g) were randomly divided into 3 groups of 3

rats each Group A normal received normal saline only Edema was induced in the remaining

groups B-CGroup B (toxic control) received carrageenan only without the drug The C

received an application of herbal gel (1g) andor treatment plantar injection of 01 mL of a

1 carageenan wv freshly prepare carageenan in normal saline was given into the left hind

paw of each rat After One hour the gel was applied to the left hind paw of each rat of treated

group Measurements of the paw volume up to the ankle joint were performed before and at

different time intervals (1 2 3 4 5 6 8 10 12h) following the Carrageenan injection using

plethysmometer

Percentage reduction calculated in edema was as follows

Inhibition = Edema (Control) minus Edema (Formulation Treated)

Edema (Control)

Arthritis Activity

Arthritis was induced in rats by subplannter injection of CFA(01 mlrat) in the right hind

paw Rats receiving CFA did not show any sign of acute toxicity Control animals were

injected with 09 saline On day 8 after adjuvant injection these rats were divided in

treatment groups (n = 6 ratsgroup) and injected daily with saline or agmatine 10 20 and 40

mgkg intraperitoneallyupto day 15 The animals were weighed daily The injections were

given daily in between 0900 and 1000 h and animals were subjected to measurement of

arthritis score[68]

as described below Thereafter they were shifted to their cages and the pre-

weighed food pellets were placed inside the cage hopper The food consumed by rats was

quantified by weighing leftover food in the hopper

Arthritis score

Evaluation of arthritis severity was performed by measuring the arthritis index of each

animal which was scored by grading eachpaw from 0 to 4 as described previously[68]

Grading was determined as follows

Rizwan et al World Journal of Pharmaceutical Research

wwwwjprnet Vol 9 Issue 1 2020

Score Sign

0 No erythema or swelling

1 Slight erythema or swelling of one or more digits

2 Swelling of the entire paw

3 Erythema and swelling of the ankle

4 Ankylosis incapacity to bend the ankle

The severity score was the sum of the arthritis scores of the right hind limb maximum upto 4

On day 15 after adjuvant injection blood was withdrawn by retro-orbital method for

biochemical analysis

Paw Volume

The paw volumes of all animals were measured daily till day 15using a plethysmometer (VJ

instrument India) The change in pawvolume was measured as the difference between the

final and initial paw volumes

4 SUMMARY AND CONCLUSION

Boswellia serrata and Commiphora mukul is an anti-inflammatory and anti-arthritic drugs

used in the treatment of joint pain inflammation and arthritis The purpose of the topical and

dermatological dosage form is to conveniently deliver drug molecules across localized area of

skin Sustained release becomes important to supply the skin with a drug over a prolonged

period of time hence a dermatological delivery system such as gel was considered to be

1213

formulated Beside this gel form may reduce the frequency of dosing intervals and may

improve patient compliance The preliminary phytochemical screening of the extract was

done in view to know the various classes of chemical constituents i e secondary metabolites

From the results of the phytochemical screening of the extracts it was observed that the

fractional product of Commiphora mukul resin contained triterpenoids and sterols

Development of gel was done by using carbapol 934 which was analyzed with a smooth and

homogeneous appearance It was easily spreadable with an acceptable mechanical property

The observation of pH revealed that all the formulations were very near to skin pH make it

suitable for application on skin The results obtained from present work indicated that the

entire drug was uniformly distributed and there was no precipitation in formulation For the

incorporation of drugs five formulae for gel were tried During comparison of these

formulae it was observed that formula 3 showed the smooth texture optimum pH and good

spreadability Hence formula 3 was taken for further studies In vitro drug release of

Boswellic acid and Guggulsterones from gel was performed to study the release behavior of

drug from formulation From the observed results it was concluded that there is increase in

the drug release with respect to time From a patient compliance point of view spreadability

is a important for topical drug delivery system The gel was found to exhibit good percentage

spread by weight that would assure the skin application Anti-Inflammatory Anti-Arthritic

study and Arthritis scoring of the prepared gel formulation evident the Anti-Arthritic activity

of the prepared herbal gel formulation Temperature stability study was performed to evaluate

the separation as well as precipitation of the drug in the excipients mixture It was observed

that the formulation was stable at different temperatures (room temperature cool

temperature elevated temperature and at 75 RH) for 60 days

In the present work the attempt was made to formulate and evaluate a gel for anti-arthritic

activity using extracts of Boswellia serrata and Commiphora mukul The results showed that

the content of Gel components had significant effect on their physical rheological and in

vitro drug release characteristics

Preformulation studies[44 45 46]

It mainly involved two parameters organoleptic and physicochemical properties of the API

used This was mainly done to check the purity of the drug and any deviation could also help

to know if there is any deterioration involved

Organoleptic Properties

Appearance

Colour

Odour

Melting point

All the above studies were carried out by using no special equipement these were done by

visual assessment

Identification of Pure Drug

The thin layer chromatography (TLC) method is used to identification of isolated compound

to standard compound or marker in which the Rf value was noted

Solubility studies

A solubility study was carried out to find out the solubility of drug in different solvents

According to this method the pure drug was added to the solvent medium and shaken for 2

hr The saturation was confirmed by observation of presence of undissolved material After

filtration of the slurry sample was analyzed using UV Visible spectrophotometer at 252 - 255

nm

Formulation development[444546]

Evaluation of Gel[474849]

Determination of pH

The pH meter was calibrated with buffered solution at 40 70 and 92 before starting pH

determination The glass electrode of the pH meter was immersed into the 50 ml beaker

containing 50 g gel and pH was noted

Homogeneacity

Homogeneacity was checked by visual inspection

Spreadability

The Spreadability of the formulation was determined by an apparatus suggested by muttimer

et al which was suitably modified in the laboratory and used for the study It consists of a

wooden block which was provided by a pulley at one end A rectangular ground glass plate

was fixed on this block An excess of gel (about 1 g) under the study was placed on this

ground plate The gel was then sandwiched between this plate and another glass plate having

the dimension of fixed ground plate and provided with the hook A 1 kg weight was placed

on the top of two plates for 5 minutes to expel air and to provide a uniform film of the gel

between the plates Excess of gel was scrapped off from the edges The top plate was then

subjected to pull of 10g with the help of string attached to the hook and the time (in second)

required by the top plate to cover a distance of 5 cm was noted

Spreadability = mlt

l= length of glass slide (75 cm)

t= time in seconds

Skin irritancy test

This test was performed on human volunteers Twenty volunteers were chosen for single

formulation and study was performed after taking their informed consent It was performed

by applying gel on an area of 2 square inch to the back of hand Then the examination for the

presence of lesion or irritation was done

Drug Content Studies Accurately weighed 1 g of gel was transferred into 100 ml

volumetric flask containing 20 ml of saline phosphate buffer (pH 68) and stirred for 30 min

followed by sonication The volume was made up to 100 ml with saline phosphate buffer (pH

68) After suitable dilution the absorbance was measured using Shimadzu 1700 UV Visible

spectrophotometer at 210 ndash 215 nm

Viscosity measurement Viscosity of the gel was determined by using Brookfield

viscometer Accurately weighed 100 g of gel was transferred to 100 ml glass beaker Spindle

no S64 was selected and it is immersed into the gel The viscometer was operated at various

rpm until the reading gets stabilized and reading was noted in centipoises It was noted from

the literature that the formulations after gelling should have a viscosity of 50 ndash 50000 cps

In vitro diffusion studies[50]

In-vitrodiffusion study was carried out in a Modified Franz diffusion cell using cellophane

membrane which is heated for 1hr in boiling water The membrane was tied to the donor

compartment and mounted on the reservoir compartment of Franz diffusion cell containing

21 ml of pH 68 phosphate buffer 1 g of Boswellia serrate and Commiphoramukulgel was

placed over the cellophane membrane of donor compartment Whole set was placed on the

magnetic stirrer The study was carried out at 37plusmn 05 ordmC and 100 rpm Samples were

withdrawn from the sampling port of reservoir compartment at regular intervals and

absorbance was measured using Shimadzu 2300 UV visible spectrophotometer at 210 ndash 215

In vivo anti-inflammatory activity[5152535455565758596061 62636465 6667]

Carrageenan induced rat paw edema model volume was used to assess the anti-inflammatory

activity of developed herbal carbopol gel Left hind paws of each Rat were just marked

beyond the tibiotarsal junction so that every time the paw is dipped up to the fixed mark to

ensure constant paw volume The rats (180ndash200g) were randomly divided into 3 groups of 3

rats each Group A normal received normal saline only Edema was induced in the remaining

groups B-CGroup B (toxic control) received carrageenan only without the drug The C

received an application of herbal gel (1g) andor treatment plantar injection of 01 mL of a

1 carageenan wv freshly prepare carageenan in normal saline was given into the left hind

paw of each rat After One hour the gel was applied to the left hind paw of each rat of treated

group Measurements of the paw volume up to the ankle joint were performed before and at

different time intervals (1 2 3 4 5 6 8 10 12h) following the Carrageenan injection using

plethysmometer

Percentage reduction calculated in edema was as follows

Inhibition = Edema (Control) minus Edema (Formulation Treated)

Edema (Control)

Arthritis Activity

Arthritis was induced in rats by subplannter injection of CFA(01 mlrat) in the right hind

paw Rats receiving CFA did not show any sign of acute toxicity Control animals were

injected with 09 saline On day 8 after adjuvant injection these rats were divided in

treatment groups (n = 6 ratsgroup) and injected daily with saline or agmatine 10 20 and 40

mgkg intraperitoneallyupto day 15 The animals were weighed daily The injections were

given daily in between 0900 and 1000 h and animals were subjected to measurement of

arthritis score[68]

as described below Thereafter they were shifted to their cages and the pre-

weighed food pellets were placed inside the cage hopper The food consumed by rats was

quantified by weighing leftover food in the hopper

Arthritis score

Evaluation of arthritis severity was performed by measuring the arthritis index of each

animal which was scored by grading eachpaw from 0 to 4 as described previously[68]

Grading was determined as follows

Rizwan et al World Journal of Pharmaceutical Research

wwwwjprnet Vol 9 Issue 1 2020

1202

Table 23 Arthritis Score

Score Sign

0 No erythema or swelling

1 Slight erythema or swelling of one or more digits

2 Swelling of the entire paw

3 Erythema and swelling of the ankle

4 Ankylosis incapacity to bend the ankle

The severity score was the sum of the arthritis scores of the right hind limb maximum upto 4

On day 15 after adjuvant injection blood was withdrawn by retro-orbital method for

biochemical analysis

Paw Volume

The paw volumes of all animals were measured daily till day 15using a plethysmometer (VJ

instrument India) The change in pawvolume was measured as the difference between the

final and initial paw volumes

Stability studies[6970]

Stability studies of drug product being as a part of drug discovery and ends with the

commercial products to assess the drug and formulation stability stability study were carried

out for most satisfactory formulation was sealed in glass vial and kept at 30 plusmn2ordmC and 40

4 SUMMARY AND CONCLUSION

Boswellia serrata and Commiphora mukul is an anti-inflammatory and anti-arthritic drugs

used in the treatment of joint pain inflammation and arthritis The purpose of the topical and

dermatological dosage form is to conveniently deliver drug molecules across localized area of

skin Sustained release becomes important to supply the skin with a drug over a prolonged

period of time hence a dermatological delivery system such as gel was considered to be

formulated Beside this gel form may reduce the frequency of dosing intervals and may

improve patient compliance The preliminary phytochemical screening of the extract was

done in view to know the various classes of chemical constituents i e secondary metabolites

From the results of the phytochemical screening of the extracts it was observed that the

fractional product of Commiphora mukul resin contained triterpenoids and sterols

Development of gel was done by using carbapol 934 which was analyzed with a smooth and

homogeneous appearance It was easily spreadable with an acceptable mechanical property

The observation of pH revealed that all the formulations were very near to skin pH make it

suitable for application on skin The results obtained from present work indicated that the

entire drug was uniformly distributed and there was no precipitation in formulation For the

incorporation of drugs five formulae for gel were tried During comparison of these

formulae it was observed that formula 3 showed the smooth texture optimum pH and good

spreadability Hence formula 3 was taken for further studies In vitro drug release of

Boswellic acid and Guggulsterones from gel was performed to study the release behavior of

drug from formulation From the observed results it was concluded that there is increase in

the drug release with respect to time From a patient compliance point of view spreadability

is a important for topical drug delivery system The gel was found to exhibit good percentage

spread by weight that would assure the skin application Anti-Inflammatory Anti-Arthritic

study and Arthritis scoring of the prepared gel formulation evident the Anti-Arthritic activity

of the prepared herbal gel formulation Temperature stability study was performed to evaluate

the separation as well as precipitation of the drug in the excipients mixture It was observed

that the formulation was stable at different temperatures (room temperature cool

temperature elevated temperature and at 75 RH) for 60 days

In the present work the attempt was made to formulate and evaluate a gel for anti-arthritic

activity using extracts of Boswellia serrata and Commiphora mukul The results showed that

the content of Gel components had significant effect on their physical rheological and in

vitro drug release characteristics

Evaluation of Gel[474849]

Determination of pH

The pH meter was calibrated with buffered solution at 40 70 and 92 before starting pH

determination The glass electrode of the pH meter was immersed into the 50 ml beaker

containing 50 g gel and pH was noted

Homogeneacity

Homogeneacity was checked by visual inspection

Spreadability

The Spreadability of the formulation was determined by an apparatus suggested by muttimer

et al which was suitably modified in the laboratory and used for the study It consists of a

wooden block which was provided by a pulley at one end A rectangular ground glass plate

was fixed on this block An excess of gel (about 1 g) under the study was placed on this

ground plate The gel was then sandwiched between this plate and another glass plate having

the dimension of fixed ground plate and provided with the hook A 1 kg weight was placed

on the top of two plates for 5 minutes to expel air and to provide a uniform film of the gel

between the plates Excess of gel was scrapped off from the edges The top plate was then

subjected to pull of 10g with the help of string attached to the hook and the time (in second)

required by the top plate to cover a distance of 5 cm was noted

Skin irritancy test

This test was performed on human volunteers Twenty volunteers were chosen for single

formulation and study was performed after taking their informed consent It was performed

by applying gel on an area of 2 square inch to the back of hand Then the examination for the

presence of lesion or irritation was done

Drug Content Studies Accurately weighed 1 g of gel was transferred into 100 ml

volumetric flask containing 20 ml of saline phosphate buffer (pH 68) and stirred for 30 min

followed by sonication The volume was made up to 100 ml with saline phosphate buffer (pH

68) After suitable dilution the absorbance was measured using Shimadzu 1700 UV Visible

spectrophotometer at 210 ndash 215 nm

Viscosity measurement Viscosity of the gel was determined by using Brookfield

viscometer Accurately weighed 100 g of gel was transferred to 100 ml glass beaker Spindle

no S64 was selected and it is immersed into the gel The viscometer was operated at various

rpm until the reading gets stabilized and reading was noted in centipoises It was noted from

the literature that the formulations after gelling should have a viscosity of 50 ndash 50000 cps

In vitro diffusion studies[50]

In-vitrodiffusion study was carried out in a Modified Franz diffusion cell using cellophane

membrane which is heated for 1hr in boiling water The membrane was tied to the donor

compartment and mounted on the reservoir compartment of Franz diffusion cell containing

21 ml of pH 68 phosphate buffer 1 g of Boswellia serrate and Commiphoramukulgel was

placed over the cellophane membrane of donor compartment Whole set was placed on the

magnetic stirrer The study was carried out at 37plusmn 05 ordmC and 100 rpm Samples were

withdrawn from the sampling port of reservoir compartment at regular intervals and

absorbance was measured using Shimadzu 2300 UV visible spectrophotometer at 210 ndash 215

In vivo anti-inflammatory activity[5152535455565758596061 62636465 6667]

Carrageenan induced rat paw edema model volume was used to assess the anti-inflammatory

activity of developed herbal carbopol gel Left hind paws of each Rat were just marked

beyond the tibiotarsal junction so that every time the paw is dipped up to the fixed mark to

ensure constant paw volume The rats (180ndash200g) were randomly divided into 3 groups of 3

rats each Group A normal received normal saline only Edema was induced in the remaining

groups B-CGroup B (toxic control) received carrageenan only without the drug The C

received an application of herbal gel (1g) andor treatment plantar injection of 01 mL of a

1 carageenan wv freshly prepare carageenan in normal saline was given into the left hind

paw of each rat After One hour the gel was applied to the left hind paw of each rat of treated

group Measurements of the paw volume up to the ankle joint were performed before and at

different time intervals (1 2 3 4 5 6 8 10 12h) following the Carrageenan injection using

plethysmometer

Percentage reduction calculated in edema was as follows

Inhibition = Edema (Control) minus Edema (Formulation Treated)

Edema (Control)

Arthritis Activity

Arthritis was induced in rats by subplannter injection of CFA(01 mlrat) in the right hind

paw Rats receiving CFA did not show any sign of acute toxicity Control animals were

injected with 09 saline On day 8 after adjuvant injection these rats were divided in

treatment groups (n = 6 ratsgroup) and injected daily with saline or agmatine 10 20 and 40

mgkg intraperitoneallyupto day 15 The animals were weighed daily The injections were

given daily in between 0900 and 1000 h and animals were subjected to measurement of

arthritis score[68]

as described below Thereafter they were shifted to their cages and the pre-

weighed food pellets were placed inside the cage hopper The food consumed by rats was

quantified by weighing leftover food in the hopper

Arthritis score

Evaluation of arthritis severity was performed by measuring the arthritis index of each

animal which was scored by grading eachpaw from 0 to 4 as described previously[68]

Grading was determined as follows

Rizwan et al World Journal of Pharmaceutical Research

wwwwjprnet Vol 9 Issue 1 2020

Score Sign

0 No erythema or swelling

1 Slight erythema or swelling of one or more digits

2 Swelling of the entire paw

3 Erythema and swelling of the ankle

4 Ankylosis incapacity to bend the ankle

The severity score was the sum of the arthritis scores of the right hind limb maximum upto 4

On day 15 after adjuvant injection blood was withdrawn by retro-orbital method for

biochemical analysis

Paw Volume

The paw volumes of all animals were measured daily till day 15using a plethysmometer (VJ

instrument India) The change in pawvolume was measured as the difference between the

final and initial paw volumes

4 SUMMARY AND CONCLUSION

Boswellia serrata and Commiphora mukul is an anti-inflammatory and anti-arthritic drugs

used in the treatment of joint pain inflammation and arthritis The purpose of the topical and

dermatological dosage form is to conveniently deliver drug molecules across localized area of

skin Sustained release becomes important to supply the skin with a drug over a prolonged

period of time hence a dermatological delivery system such as gel was considered to be

formulated Beside this gel form may reduce the frequency of dosing intervals and may

improve patient compliance The preliminary phytochemical screening of the extract was

done in view to know the various classes of chemical constituents i e secondary metabolites

From the results of the phytochemical screening of the extracts it was observed that the

fractional product of Commiphora mukul resin contained triterpenoids and sterols

Development of gel was done by using carbapol 934 which was analyzed with a smooth and

homogeneous appearance It was easily spreadable with an acceptable mechanical property

The observation of pH revealed that all the formulations were very near to skin pH make it

suitable for application on skin The results obtained from present work indicated that the

entire drug was uniformly distributed and there was no precipitation in formulation For the

incorporation of drugs five formulae for gel were tried During comparison of these

formulae it was observed that formula 3 showed the smooth texture optimum pH and good

spreadability Hence formula 3 was taken for further studies In vitro drug release of

Boswellic acid and Guggulsterones from gel was performed to study the release behavior of

drug from formulation From the observed results it was concluded that there is increase in

the drug release with respect to time From a patient compliance point of view spreadability

is a important for topical drug delivery system The gel was found to exhibit good percentage

spread by weight that would assure the skin application Anti-Inflammatory Anti-Arthritic

study and Arthritis scoring of the prepared gel formulation evident the Anti-Arthritic activity

of the prepared herbal gel formulation Temperature stability study was performed to evaluate

the separation as well as precipitation of the drug in the excipients mixture It was observed

that the formulation was stable at different temperatures (room temperature cool

temperature elevated temperature and at 75 RH) for 60 days

In the present work the attempt was made to formulate and evaluate a gel for anti-arthritic

activity using extracts of Boswellia serrata and Commiphora mukul The results showed that

the content of Gel components had significant effect on their physical rheological and in

vitro drug release characteristics

Skin irritancy test

This test was performed on human volunteers Twenty volunteers were chosen for single

formulation and study was performed after taking their informed consent It was performed

by applying gel on an area of 2 square inch to the back of hand Then the examination for the

presence of lesion or irritation was done

Drug Content Studies Accurately weighed 1 g of gel was transferred into 100 ml

volumetric flask containing 20 ml of saline phosphate buffer (pH 68) and stirred for 30 min

followed by sonication The volume was made up to 100 ml with saline phosphate buffer (pH

68) After suitable dilution the absorbance was measured using Shimadzu 1700 UV Visible

spectrophotometer at 210 ndash 215 nm

Viscosity measurement Viscosity of the gel was determined by using Brookfield

viscometer Accurately weighed 100 g of gel was transferred to 100 ml glass beaker Spindle

no S64 was selected and it is immersed into the gel The viscometer was operated at various

rpm until the reading gets stabilized and reading was noted in centipoises It was noted from

the literature that the formulations after gelling should have a viscosity of 50 ndash 50000 cps

In vitro diffusion studies[50]

In-vitrodiffusion study was carried out in a Modified Franz diffusion cell using cellophane

membrane which is heated for 1hr in boiling water The membrane was tied to the donor

compartment and mounted on the reservoir compartment of Franz diffusion cell containing

21 ml of pH 68 phosphate buffer 1 g of Boswellia serrate and Commiphoramukulgel was

placed over the cellophane membrane of donor compartment Whole set was placed on the

magnetic stirrer The study was carried out at 37plusmn 05 ordmC and 100 rpm Samples were

withdrawn from the sampling port of reservoir compartment at regular intervals and

absorbance was measured using Shimadzu 2300 UV visible spectrophotometer at 210 ndash 215

In vivo anti-inflammatory activity[5152535455565758596061 62636465 6667]

Carrageenan induced rat paw edema model volume was used to assess the anti-inflammatory

activity of developed herbal carbopol gel Left hind paws of each Rat were just marked

beyond the tibiotarsal junction so that every time the paw is dipped up to the fixed mark to

ensure constant paw volume The rats (180ndash200g) were randomly divided into 3 groups of 3

rats each Group A normal received normal saline only Edema was induced in the remaining

groups B-CGroup B (toxic control) received carrageenan only without the drug The C

received an application of herbal gel (1g) andor treatment plantar injection of 01 mL of a

1 carageenan wv freshly prepare carageenan in normal saline was given into the left hind

paw of each rat After One hour the gel was applied to the left hind paw of each rat of treated

group Measurements of the paw volume up to the ankle joint were performed before and at

different time intervals (1 2 3 4 5 6 8 10 12h) following the Carrageenan injection using

plethysmometer

Percentage reduction calculated in edema was as follows

Inhibition = Edema (Control) minus Edema (Formulation Treated)

Edema (Control)

Arthritis Activity

Arthritis was induced in rats by subplannter injection of CFA(01 mlrat) in the right hind

paw Rats receiving CFA did not show any sign of acute toxicity Control animals were

injected with 09 saline On day 8 after adjuvant injection these rats were divided in

treatment groups (n = 6 ratsgroup) and injected daily with saline or agmatine 10 20 and 40

mgkg intraperitoneallyupto day 15 The animals were weighed daily The injections were

given daily in between 0900 and 1000 h and animals were subjected to measurement of

arthritis score[68]

as described below Thereafter they were shifted to their cages and the pre-

weighed food pellets were placed inside the cage hopper The food consumed by rats was

quantified by weighing leftover food in the hopper

Arthritis score

Evaluation of arthritis severity was performed by measuring the arthritis index of each

animal which was scored by grading eachpaw from 0 to 4 as described previously[68]

Grading was determined as follows

Rizwan et al World Journal of Pharmaceutical Research

wwwwjprnet Vol 9 Issue 1 2020

1202

Table 23 Arthritis Score

Score Sign

0 No erythema or swelling

1 Slight erythema or swelling of one or more digits

2 Swelling of the entire paw

3 Erythema and swelling of the ankle

4 Ankylosis incapacity to bend the ankle

The severity score was the sum of the arthritis scores of the right hind limb maximum upto 4

On day 15 after adjuvant injection blood was withdrawn by retro-orbital method for

biochemical analysis

Paw Volume

The paw volumes of all animals were measured daily till day 15using a plethysmometer (VJ

instrument India) The change in pawvolume was measured as the difference between the

final and initial paw volumes

Stability studies[6970]

Stability studies of drug product being as a part of drug discovery and ends with the

commercial products to assess the drug and formulation stability stability study were carried

out for most satisfactory formulation was sealed in glass vial and kept at 30 plusmn2ordmC and 40

plusmn2ordmC at RH 65 plusmn 5 and 75 plusmn 5 RH for 2 months At the end of 1 and 2 months the samples

were analysed for the drug content and in-vitro diffusion study

4 SUMMARY AND CONCLUSION

Boswellia serrata and Commiphora mukul is an anti-inflammatory and anti-arthritic drugs

used in the treatment of joint pain inflammation and arthritis The purpose of the topical and

dermatological dosage form is to conveniently deliver drug molecules across localized area of

skin Sustained release becomes important to supply the skin with a drug over a prolonged

period of time hence a dermatological delivery system such as gel was considered to be

formulated Beside this gel form may reduce the frequency of dosing intervals and may

improve patient compliance The preliminary phytochemical screening of the extract was

done in view to know the various classes of chemical constituents i e secondary metabolites

From the results of the phytochemical screening of the extracts it was observed that the

fractional product of Commiphora mukul resin contained triterpenoids and sterols

Development of gel was done by using carbapol 934 which was analyzed with a smooth and

homogeneous appearance It was easily spreadable with an acceptable mechanical property

The observation of pH revealed that all the formulations were very near to skin pH make it

suitable for application on skin The results obtained from present work indicated that the

entire drug was uniformly distributed and there was no precipitation in formulation For the

incorporation of drugs five formulae for gel were tried During comparison of these

formulae it was observed that formula 3 showed the smooth texture optimum pH and good

spreadability Hence formula 3 was taken for further studies In vitro drug release of

Boswellic acid and Guggulsterones from gel was performed to study the release behavior of

drug from formulation From the observed results it was concluded that there is increase in

the drug release with respect to time From a patient compliance point of view spreadability

is a important for topical drug delivery system The gel was found to exhibit good percentage

spread by weight that would assure the skin application Anti-Inflammatory Anti-Arthritic

study and Arthritis scoring of the prepared gel formulation evident the Anti-Arthritic activity

of the prepared herbal gel formulation Temperature stability study was performed to evaluate

the separation as well as precipitation of the drug in the excipients mixture It was observed

that the formulation was stable at different temperatures (room temperature cool

temperature elevated temperature and at 75 RH) for 60 days

In the present work the attempt was made to formulate and evaluate a gel for anti-arthritic

activity using extracts of Boswellia serrata and Commiphora mukul The results showed that

the content of Gel components had significant effect on their physical rheological and in

vitro drug release characteristics

In vivo anti-inflammatory activity[5152535455565758596061 62636465 6667]

Carrageenan induced rat paw edema model volume was used to assess the anti-inflammatory

activity of developed herbal carbopol gel Left hind paws of each Rat were just marked

beyond the tibiotarsal junction so that every time the paw is dipped up to the fixed mark to

ensure constant paw volume The rats (180ndash200g) were randomly divided into 3 groups of 3

rats each Group A normal received normal saline only Edema was induced in the remaining

groups B-CGroup B (toxic control) received carrageenan only without the drug The C

received an application of herbal gel (1g) andor treatment plantar injection of 01 mL of a

1 carageenan wv freshly prepare carageenan in normal saline was given into the left hind

paw of each rat After One hour the gel was applied to the left hind paw of each rat of treated

group Measurements of the paw volume up to the ankle joint were performed before and at

different time intervals (1 2 3 4 5 6 8 10 12h) following the Carrageenan injection using

plethysmometer

Percentage reduction calculated in edema was as follows

Inhibition = Edema (Control) minus Edema (Formulation Treated)

Edema (Control)

Arthritis Activity

Arthritis was induced in rats by subplannter injection of CFA(01 mlrat) in the right hind

paw Rats receiving CFA did not show any sign of acute toxicity Control animals were

injected with 09 saline On day 8 after adjuvant injection these rats were divided in

treatment groups (n = 6 ratsgroup) and injected daily with saline or agmatine 10 20 and 40

mgkg intraperitoneallyupto day 15 The animals were weighed daily The injections were

given daily in between 0900 and 1000 h and animals were subjected to measurement of

arthritis score[68]

as described below Thereafter they were shifted to their cages and the pre-

weighed food pellets were placed inside the cage hopper The food consumed by rats was

quantified by weighing leftover food in the hopper

Arthritis score

Evaluation of arthritis severity was performed by measuring the arthritis index of each

animal which was scored by grading eachpaw from 0 to 4 as described previously[68]

Grading was determined as follows

Rizwan et al World Journal of Pharmaceutical Research

wwwwjprnet Vol 9 Issue 1 2020

1202

Table 23 Arthritis Score

Score Sign

0 No erythema or swelling

1 Slight erythema or swelling of one or more digits

2 Swelling of the entire paw

3 Erythema and swelling of the ankle

4 Ankylosis incapacity to bend the ankle

The severity score was the sum of the arthritis scores of the right hind limb maximum upto 4

On day 15 after adjuvant injection blood was withdrawn by retro-orbital method for

biochemical analysis

Paw Volume

The paw volumes of all animals were measured daily till day 15using a plethysmometer (VJ

instrument India) The change in pawvolume was measured as the difference between the

final and initial paw volumes

Stability studies[6970]

Stability studies of drug product being as a part of drug discovery and ends with the

commercial products to assess the drug and formulation stability stability study were carried

out for most satisfactory formulation was sealed in glass vial and kept at 30 plusmn2ordmC and 40

UV-Visible Spectrophotometric Analysis

UV Spectroscopy

The maximum absorption value of pure drug Boswellic acid was found at 210 ndash 215 nm

wavelengths in phosphate buffer pH 68 Therefore 210 ndash 215 nm was recorded as λmax of

the pure drug Boswellic acid The observed λmax value of drug was found to be complied

with the specification of Indian pharmacopoeia Hence the drug was considered to be pure

The UV specrum of Boswellic acid is shown in Figure 2

A solution of 100microgml of Boswellic acidwas scanned in the range of 400 to 200 nm The

drug exhibited the λmax at 320 nm and showed reproducibility

From the standard curve of Boswellic acid in phosphate buffer pH 68 it was observed that

the Boswellic acidobeys Beers-Lambertrsquos law in the range 10-50microgml in the medium as

shown in table 63 and figure 3

4 SUMMARY AND CONCLUSION

Boswellia serrata and Commiphora mukul is an anti-inflammatory and anti-arthritic drugs

used in the treatment of joint pain inflammation and arthritis The purpose of the topical and

dermatological dosage form is to conveniently deliver drug molecules across localized area of

skin Sustained release becomes important to supply the skin with a drug over a prolonged

period of time hence a dermatological delivery system such as gel was considered to be

formulated Beside this gel form may reduce the frequency of dosing intervals and may

improve patient compliance The preliminary phytochemical screening of the extract was

done in view to know the various classes of chemical constituents i e secondary metabolites

From the results of the phytochemical screening of the extracts it was observed that the

fractional product of Commiphora mukul resin contained triterpenoids and sterols

Development of gel was done by using carbapol 934 which was analyzed with a smooth and

homogeneous appearance It was easily spreadable with an acceptable mechanical property

The observation of pH revealed that all the formulations were very near to skin pH make it

suitable for application on skin The results obtained from present work indicated that the

entire drug was uniformly distributed and there was no precipitation in formulation For the

incorporation of drugs five formulae for gel were tried During comparison of these

formulae it was observed that formula 3 showed the smooth texture optimum pH and good

spreadability Hence formula 3 was taken for further studies In vitro drug release of

Boswellic acid and Guggulsterones from gel was performed to study the release behavior of

drug from formulation From the observed results it was concluded that there is increase in

the drug release with respect to time From a patient compliance point of view spreadability

is a important for topical drug delivery system The gel was found to exhibit good percentage

spread by weight that would assure the skin application Anti-Inflammatory Anti-Arthritic

study and Arthritis scoring of the prepared gel formulation evident the Anti-Arthritic activity

of the prepared herbal gel formulation Temperature stability study was performed to evaluate

the separation as well as precipitation of the drug in the excipients mixture It was observed

that the formulation was stable at different temperatures (room temperature cool

temperature elevated temperature and at 75 RH) for 60 days

In the present work the attempt was made to formulate and evaluate a gel for anti-arthritic

activity using extracts of Boswellia serrata and Commiphora mukul The results showed that

the content of Gel components had significant effect on their physical rheological and in

vitro drug release characteristics

4 SUMMARY AND CONCLUSION

Boswellia serrata and Commiphora mukul is an anti-inflammatory and anti-arthritic drugs

used in the treatment of joint pain inflammation and arthritis The purpose of the topical and

dermatological dosage form is to conveniently deliver drug molecules across localized area of

skin Sustained release becomes important to supply the skin with a drug over a prolonged

period of time hence a dermatological delivery system such as gel was considered to be

1213

formulated Beside this gel form may reduce the frequency of dosing intervals and may

improve patient compliance The preliminary phytochemical screening of the extract was

done in view to know the various classes of chemical constituents i e secondary metabolites

From the results of the phytochemical screening of the extracts it was observed that the

fractional product of Commiphora mukul resin contained triterpenoids and sterols

Development of gel was done by using carbapol 934 which was analyzed with a smooth and

homogeneous appearance It was easily spreadable with an acceptable mechanical property

The observation of pH revealed that all the formulations were very near to skin pH make it

suitable for application on skin The results obtained from present work indicated that the

entire drug was uniformly distributed and there was no precipitation in formulation For the

incorporation of drugs five formulae for gel were tried During comparison of these

formulae it was observed that formula 3 showed the smooth texture optimum pH and good

spreadability Hence formula 3 was taken for further studies In vitro drug release of

Boswellic acid and Guggulsterones from gel was performed to study the release behavior of

drug from formulation From the observed results it was concluded that there is increase in

the drug release with respect to time From a patient compliance point of view spreadability

is a important for topical drug delivery system The gel was found to exhibit good percentage

spread by weight that would assure the skin application Anti-Inflammatory Anti-Arthritic

study and Arthritis scoring of the prepared gel formulation evident the Anti-Arthritic activity

of the prepared herbal gel formulation Temperature stability study was performed to evaluate

the separation as well as precipitation of the drug in the excipients mixture It was observed

that the formulation was stable at different temperatures (room temperature cool

temperature elevated temperature and at 75 RH) for 60 days

In the present work the attempt was made to formulate and evaluate a gel for anti-arthritic

activity using extracts of Boswellia serrata and Commiphora mukul The results showed that

the content of Gel components had significant effect on their physical rheological and in

vitro drug release characteristics

4 SUMMARY AND CONCLUSION

Boswellia serrata and Commiphora mukul is an anti-inflammatory and anti-arthritic drugs

used in the treatment of joint pain inflammation and arthritis The purpose of the topical and

dermatological dosage form is to conveniently deliver drug molecules across localized area of

skin Sustained release becomes important to supply the skin with a drug over a prolonged

period of time hence a dermatological delivery system such as gel was considered to be

formulated Beside this gel form may reduce the frequency of dosing intervals and may

improve patient compliance The preliminary phytochemical screening of the extract was

done in view to know the various classes of chemical constituents i e secondary metabolites

From the results of the phytochemical screening of the extracts it was observed that the

fractional product of Commiphora mukul resin contained triterpenoids and sterols

Development of gel was done by using carbapol 934 which was analyzed with a smooth and

homogeneous appearance It was easily spreadable with an acceptable mechanical property

The observation of pH revealed that all the formulations were very near to skin pH make it

suitable for application on skin The results obtained from present work indicated that the

entire drug was uniformly distributed and there was no precipitation in formulation For the

incorporation of drugs five formulae for gel were tried During comparison of these

formulae it was observed that formula 3 showed the smooth texture optimum pH and good

spreadability Hence formula 3 was taken for further studies In vitro drug release of

Boswellic acid and Guggulsterones from gel was performed to study the release behavior of

drug from formulation From the observed results it was concluded that there is increase in

the drug release with respect to time From a patient compliance point of view spreadability

is a important for topical drug delivery system The gel was found to exhibit good percentage

spread by weight that would assure the skin application Anti-Inflammatory Anti-Arthritic

study and Arthritis scoring of the prepared gel formulation evident the Anti-Arthritic activity

of the prepared herbal gel formulation Temperature stability study was performed to evaluate

the separation as well as precipitation of the drug in the excipients mixture It was observed

that the formulation was stable at different temperatures (room temperature cool

temperature elevated temperature and at 75 RH) for 60 days

In the present work the attempt was made to formulate and evaluate a gel for anti-arthritic

activity using extracts of Boswellia serrata and Commiphora mukul The results showed that

the content of Gel components had significant effect on their physical rheological and in

vitro drug release characteristics

UV Spectroscopy

The maximum absorption value of pure drug Boswellic acid was found at 210 ndash 215 nm

wavelengths in phosphate buffer pH 68 Therefore 210 ndash 215 nm was recorded as λmax of

the pure drug Boswellic acid The observed λmax value of drug was found to be complied

with the specification of Indian pharmacopoeia Hence the drug was considered to be pure

The UV specrum of Boswellic acid is shown in Figure 2

A solution of 100microgml of Boswellic acidwas scanned in the range of 400 to 200 nm The

drug exhibited the λmax at 320 nm and showed reproducibility

From the standard curve of Boswellic acid in phosphate buffer pH 68 it was observed that

the Boswellic acidobeys Beers-Lambertrsquos law in the range 10-50microgml in the medium as

shown in table 63 and figure 3

4 SUMMARY AND CONCLUSION

Boswellia serrata and Commiphora mukul is an anti-inflammatory and anti-arthritic drugs

used in the treatment of joint pain inflammation and arthritis The purpose of the topical and

dermatological dosage form is to conveniently deliver drug molecules across localized area of

skin Sustained release becomes important to supply the skin with a drug over a prolonged

period of time hence a dermatological delivery system such as gel was considered to be

formulated Beside this gel form may reduce the frequency of dosing intervals and may

improve patient compliance The preliminary phytochemical screening of the extract was

done in view to know the various classes of chemical constituents i e secondary metabolites

From the results of the phytochemical screening of the extracts it was observed that the

fractional product of Commiphora mukul resin contained triterpenoids and sterols

Development of gel was done by using carbapol 934 which was analyzed with a smooth and

homogeneous appearance It was easily spreadable with an acceptable mechanical property

The observation of pH revealed that all the formulations were very near to skin pH make it

suitable for application on skin The results obtained from present work indicated that the

entire drug was uniformly distributed and there was no precipitation in formulation For the

incorporation of drugs five formulae for gel were tried During comparison of these

formulae it was observed that formula 3 showed the smooth texture optimum pH and good

spreadability Hence formula 3 was taken for further studies In vitro drug release of

Boswellic acid and Guggulsterones from gel was performed to study the release behavior of

drug from formulation From the observed results it was concluded that there is increase in

the drug release with respect to time From a patient compliance point of view spreadability

is a important for topical drug delivery system The gel was found to exhibit good percentage

spread by weight that would assure the skin application Anti-Inflammatory Anti-Arthritic

study and Arthritis scoring of the prepared gel formulation evident the Anti-Arthritic activity

of the prepared herbal gel formulation Temperature stability study was performed to evaluate

the separation as well as precipitation of the drug in the excipients mixture It was observed

that the formulation was stable at different temperatures (room temperature cool

temperature elevated temperature and at 75 RH) for 60 days

In the present work the attempt was made to formulate and evaluate a gel for anti-arthritic

activity using extracts of Boswellia serrata and Commiphora mukul The results showed that

the content of Gel components had significant effect on their physical rheological and in

vitro drug release characteristics

UV-Visible Spectrophotometric Analysis

a) UV Spectroscopy

The maximum absorption value of extracted drug Commiphora mukul was found at 205 nm

wavelength in phosphate buffer pH 68 Therefore 205 nm was recorded as λmax of the

extracted drug Commiphora mukul The observed λmax value of drug was found to be

complies with the specification of Indian pharmacopoeia Hence the drug was considered to

be pure The UV spectrum of Commiphora mukul is shown in Figure 64

b) Calibration curve of Commiphora mukul in phosphate buffer pH 68

A solution of 100 microgml of Commiphora mukul was scanned in the range of 200 to 400 nm

The drug exhibited the λmax at 205 nm and showed reproducibility

From the standard curve of Commiphora mukul in phosphate buffer pH 68 it was observed

that the Commiphora mukul obeys Beers-Lambertrsquos law in the range 10-50microgml in the

medium as shown in table 65 and figure 67

4 SUMMARY AND CONCLUSION

Boswellia serrata and Commiphora mukul is an anti-inflammatory and anti-arthritic drugs

used in the treatment of joint pain inflammation and arthritis The purpose of the topical and

dermatological dosage form is to conveniently deliver drug molecules across localized area of

skin Sustained release becomes important to supply the skin with a drug over a prolonged

period of time hence a dermatological delivery system such as gel was considered to be

formulated Beside this gel form may reduce the frequency of dosing intervals and may

improve patient compliance The preliminary phytochemical screening of the extract was

done in view to know the various classes of chemical constituents i e secondary metabolites

From the results of the phytochemical screening of the extracts it was observed that the

fractional product of Commiphora mukul resin contained triterpenoids and sterols

Development of gel was done by using carbapol 934 which was analyzed with a smooth and

homogeneous appearance It was easily spreadable with an acceptable mechanical property

The observation of pH revealed that all the formulations were very near to skin pH make it

suitable for application on skin The results obtained from present work indicated that the

entire drug was uniformly distributed and there was no precipitation in formulation For the

incorporation of drugs five formulae for gel were tried During comparison of these

formulae it was observed that formula 3 showed the smooth texture optimum pH and good

spreadability Hence formula 3 was taken for further studies In vitro drug release of

Boswellic acid and Guggulsterones from gel was performed to study the release behavior of

drug from formulation From the observed results it was concluded that there is increase in

the drug release with respect to time From a patient compliance point of view spreadability

is a important for topical drug delivery system The gel was found to exhibit good percentage

spread by weight that would assure the skin application Anti-Inflammatory Anti-Arthritic

study and Arthritis scoring of the prepared gel formulation evident the Anti-Arthritic activity

of the prepared herbal gel formulation Temperature stability study was performed to evaluate

the separation as well as precipitation of the drug in the excipients mixture It was observed

that the formulation was stable at different temperatures (room temperature cool

temperature elevated temperature and at 75 RH) for 60 days

In the present work the attempt was made to formulate and evaluate a gel for anti-arthritic

activity using extracts of Boswellia serrata and Commiphora mukul The results showed that

the content of Gel components had significant effect on their physical rheological and in

vitro drug release characteristics

UV-Visible Spectrophotometric Analysis

a) UV Spectroscopy

The maximum absorption value of extracted drug Commiphora mukul was found at 205 nm

wavelength in phosphate buffer pH 68 Therefore 205 nm was recorded as λmax of the

extracted drug Commiphora mukul The observed λmax value of drug was found to be

complies with the specification of Indian pharmacopoeia Hence the drug was considered to

be pure The UV spectrum of Commiphora mukul is shown in Figure 64

b) Calibration curve of Commiphora mukul in phosphate buffer pH 68

A solution of 100 microgml of Commiphora mukul was scanned in the range of 200 to 400 nm

The drug exhibited the λmax at 205 nm and showed reproducibility

From the standard curve of Commiphora mukul in phosphate buffer pH 68 it was observed

that the Commiphora mukul obeys Beers-Lambertrsquos law in the range 10-50microgml in the

medium as shown in table 65 and figure 67

4 SUMMARY AND CONCLUSION

Boswellia serrata and Commiphora mukul is an anti-inflammatory and anti-arthritic drugs

used in the treatment of joint pain inflammation and arthritis The purpose of the topical and

dermatological dosage form is to conveniently deliver drug molecules across localized area of

skin Sustained release becomes important to supply the skin with a drug over a prolonged

period of time hence a dermatological delivery system such as gel was considered to be

1213

formulated Beside this gel form may reduce the frequency of dosing intervals and may

improve patient compliance The preliminary phytochemical screening of the extract was

done in view to know the various classes of chemical constituents i e secondary metabolites

From the results of the phytochemical screening of the extracts it was observed that the

fractional product of Commiphora mukul resin contained triterpenoids and sterols

Development of gel was done by using carbapol 934 which was analyzed with a smooth and

homogeneous appearance It was easily spreadable with an acceptable mechanical property

The observation of pH revealed that all the formulations were very near to skin pH make it

suitable for application on skin The results obtained from present work indicated that the

entire drug was uniformly distributed and there was no precipitation in formulation For the

incorporation of drugs five formulae for gel were tried During comparison of these

formulae it was observed that formula 3 showed the smooth texture optimum pH and good

spreadability Hence formula 3 was taken for further studies In vitro drug release of

Boswellic acid and Guggulsterones from gel was performed to study the release behavior of

drug from formulation From the observed results it was concluded that there is increase in

the drug release with respect to time From a patient compliance point of view spreadability

is a important for topical drug delivery system The gel was found to exhibit good percentage

spread by weight that would assure the skin application Anti-Inflammatory Anti-Arthritic

study and Arthritis scoring of the prepared gel formulation evident the Anti-Arthritic activity

of the prepared herbal gel formulation Temperature stability study was performed to evaluate

the separation as well as precipitation of the drug in the excipients mixture It was observed

that the formulation was stable at different temperatures (room temperature cool

temperature elevated temperature and at 75 RH) for 60 days

In the present work the attempt was made to formulate and evaluate a gel for anti-arthritic

activity using extracts of Boswellia serrata and Commiphora mukul The results showed that

the content of Gel components had significant effect on their physical rheological and in

vitro drug release characteristics

4 SUMMARY AND CONCLUSION

Boswellia serrata and Commiphora mukul is an anti-inflammatory and anti-arthritic drugs

used in the treatment of joint pain inflammation and arthritis The purpose of the topical and

dermatological dosage form is to conveniently deliver drug molecules across localized area of

skin Sustained release becomes important to supply the skin with a drug over a prolonged

period of time hence a dermatological delivery system such as gel was considered to be

formulated Beside this gel form may reduce the frequency of dosing intervals and may

improve patient compliance The preliminary phytochemical screening of the extract was

done in view to know the various classes of chemical constituents i e secondary metabolites

From the results of the phytochemical screening of the extracts it was observed that the

fractional product of Commiphora mukul resin contained triterpenoids and sterols

Development of gel was done by using carbapol 934 which was analyzed with a smooth and

homogeneous appearance It was easily spreadable with an acceptable mechanical property

The observation of pH revealed that all the formulations were very near to skin pH make it

suitable for application on skin The results obtained from present work indicated that the

entire drug was uniformly distributed and there was no precipitation in formulation For the

incorporation of drugs five formulae for gel were tried During comparison of these

formulae it was observed that formula 3 showed the smooth texture optimum pH and good

spreadability Hence formula 3 was taken for further studies In vitro drug release of

Boswellic acid and Guggulsterones from gel was performed to study the release behavior of

drug from formulation From the observed results it was concluded that there is increase in

the drug release with respect to time From a patient compliance point of view spreadability

is a important for topical drug delivery system The gel was found to exhibit good percentage

spread by weight that would assure the skin application Anti-Inflammatory Anti-Arthritic

study and Arthritis scoring of the prepared gel formulation evident the Anti-Arthritic activity

of the prepared herbal gel formulation Temperature stability study was performed to evaluate

the separation as well as precipitation of the drug in the excipients mixture It was observed

that the formulation was stable at different temperatures (room temperature cool

temperature elevated temperature and at 75 RH) for 60 days

In the present work the attempt was made to formulate and evaluate a gel for anti-arthritic

activity using extracts of Boswellia serrata and Commiphora mukul The results showed that

the content of Gel components had significant effect on their physical rheological and in

vitro drug release characteristics

4 SUMMARY AND CONCLUSION

Boswellia serrata and Commiphora mukul is an anti-inflammatory and anti-arthritic drugs

used in the treatment of joint pain inflammation and arthritis The purpose of the topical and

dermatological dosage form is to conveniently deliver drug molecules across localized area of

skin Sustained release becomes important to supply the skin with a drug over a prolonged

period of time hence a dermatological delivery system such as gel was considered to be

formulated Beside this gel form may reduce the frequency of dosing intervals and may

improve patient compliance The preliminary phytochemical screening of the extract was

done in view to know the various classes of chemical constituents i e secondary metabolites

From the results of the phytochemical screening of the extracts it was observed that the

fractional product of Commiphora mukul resin contained triterpenoids and sterols

Development of gel was done by using carbapol 934 which was analyzed with a smooth and

homogeneous appearance It was easily spreadable with an acceptable mechanical property

The observation of pH revealed that all the formulations were very near to skin pH make it

suitable for application on skin The results obtained from present work indicated that the

entire drug was uniformly distributed and there was no precipitation in formulation For the

incorporation of drugs five formulae for gel were tried During comparison of these

formulae it was observed that formula 3 showed the smooth texture optimum pH and good

spreadability Hence formula 3 was taken for further studies In vitro drug release of

Boswellic acid and Guggulsterones from gel was performed to study the release behavior of

drug from formulation From the observed results it was concluded that there is increase in

the drug release with respect to time From a patient compliance point of view spreadability

is a important for topical drug delivery system The gel was found to exhibit good percentage

spread by weight that would assure the skin application Anti-Inflammatory Anti-Arthritic

study and Arthritis scoring of the prepared gel formulation evident the Anti-Arthritic activity

of the prepared herbal gel formulation Temperature stability study was performed to evaluate

the separation as well as precipitation of the drug in the excipients mixture It was observed

that the formulation was stable at different temperatures (room temperature cool

temperature elevated temperature and at 75 RH) for 60 days

In the present work the attempt was made to formulate and evaluate a gel for anti-arthritic

activity using extracts of Boswellia serrata and Commiphora mukul The results showed that

the content of Gel components had significant effect on their physical rheological and in

vitro drug release characteristics

4 SUMMARY AND CONCLUSION

Boswellia serrata and Commiphora mukul is an anti-inflammatory and anti-arthritic drugs

used in the treatment of joint pain inflammation and arthritis The purpose of the topical and

dermatological dosage form is to conveniently deliver drug molecules across localized area of

skin Sustained release becomes important to supply the skin with a drug over a prolonged

period of time hence a dermatological delivery system such as gel was considered to be

formulated Beside this gel form may reduce the frequency of dosing intervals and may

improve patient compliance The preliminary phytochemical screening of the extract was

done in view to know the various classes of chemical constituents i e secondary metabolites

From the results of the phytochemical screening of the extracts it was observed that the

fractional product of Commiphora mukul resin contained triterpenoids and sterols

Development of gel was done by using carbapol 934 which was analyzed with a smooth and

homogeneous appearance It was easily spreadable with an acceptable mechanical property

The observation of pH revealed that all the formulations were very near to skin pH make it

suitable for application on skin The results obtained from present work indicated that the

entire drug was uniformly distributed and there was no precipitation in formulation For the

incorporation of drugs five formulae for gel were tried During comparison of these

formulae it was observed that formula 3 showed the smooth texture optimum pH and good

spreadability Hence formula 3 was taken for further studies In vitro drug release of

Boswellic acid and Guggulsterones from gel was performed to study the release behavior of

drug from formulation From the observed results it was concluded that there is increase in

the drug release with respect to time From a patient compliance point of view spreadability

is a important for topical drug delivery system The gel was found to exhibit good percentage

spread by weight that would assure the skin application Anti-Inflammatory Anti-Arthritic

study and Arthritis scoring of the prepared gel formulation evident the Anti-Arthritic activity

of the prepared herbal gel formulation Temperature stability study was performed to evaluate

the separation as well as precipitation of the drug in the excipients mixture It was observed

that the formulation was stable at different temperatures (room temperature cool

temperature elevated temperature and at 75 RH) for 60 days

In the present work the attempt was made to formulate and evaluate a gel for anti-arthritic

activity using extracts of Boswellia serrata and Commiphora mukul The results showed that

the content of Gel components had significant effect on their physical rheological and in

vitro drug release characteristics

4 SUMMARY AND CONCLUSION

Boswellia serrata and Commiphora mukul is an anti-inflammatory and anti-arthritic drugs

used in the treatment of joint pain inflammation and arthritis The purpose of the topical and

dermatological dosage form is to conveniently deliver drug molecules across localized area of

skin Sustained release becomes important to supply the skin with a drug over a prolonged

period of time hence a dermatological delivery system such as gel was considered to be

formulated Beside this gel form may reduce the frequency of dosing intervals and may

improve patient compliance The preliminary phytochemical screening of the extract was

done in view to know the various classes of chemical constituents i e secondary metabolites

From the results of the phytochemical screening of the extracts it was observed that the

fractional product of Commiphora mukul resin contained triterpenoids and sterols

Development of gel was done by using carbapol 934 which was analyzed with a smooth and

homogeneous appearance It was easily spreadable with an acceptable mechanical property

The observation of pH revealed that all the formulations were very near to skin pH make it

suitable for application on skin The results obtained from present work indicated that the

entire drug was uniformly distributed and there was no precipitation in formulation For the

incorporation of drugs five formulae for gel were tried During comparison of these

formulae it was observed that formula 3 showed the smooth texture optimum pH and good

spreadability Hence formula 3 was taken for further studies In vitro drug release of

Boswellic acid and Guggulsterones from gel was performed to study the release behavior of

drug from formulation From the observed results it was concluded that there is increase in

the drug release with respect to time From a patient compliance point of view spreadability

is a important for topical drug delivery system The gel was found to exhibit good percentage

spread by weight that would assure the skin application Anti-Inflammatory Anti-Arthritic

study and Arthritis scoring of the prepared gel formulation evident the Anti-Arthritic activity

of the prepared herbal gel formulation Temperature stability study was performed to evaluate

the separation as well as precipitation of the drug in the excipients mixture It was observed

that the formulation was stable at different temperatures (room temperature cool

temperature elevated temperature and at 75 RH) for 60 days

In the present work the attempt was made to formulate and evaluate a gel for anti-arthritic

activity using extracts of Boswellia serrata and Commiphora mukul The results showed that

the content of Gel components had significant effect on their physical rheological and in

vitro drug release characteristics

4 SUMMARY AND CONCLUSION

Boswellia serrata and Commiphora mukul is an anti-inflammatory and anti-arthritic drugs

used in the treatment of joint pain inflammation and arthritis The purpose of the topical and

dermatological dosage form is to conveniently deliver drug molecules across localized area of

skin Sustained release becomes important to supply the skin with a drug over a prolonged

period of time hence a dermatological delivery system such as gel was considered to be

formulated Beside this gel form may reduce the frequency of dosing intervals and may

improve patient compliance The preliminary phytochemical screening of the extract was

done in view to know the various classes of chemical constituents i e secondary metabolites

From the results of the phytochemical screening of the extracts it was observed that the

fractional product of Commiphora mukul resin contained triterpenoids and sterols

Development of gel was done by using carbapol 934 which was analyzed with a smooth and

homogeneous appearance It was easily spreadable with an acceptable mechanical property

The observation of pH revealed that all the formulations were very near to skin pH make it

suitable for application on skin The results obtained from present work indicated that the

entire drug was uniformly distributed and there was no precipitation in formulation For the

incorporation of drugs five formulae for gel were tried During comparison of these

formulae it was observed that formula 3 showed the smooth texture optimum pH and good

spreadability Hence formula 3 was taken for further studies In vitro drug release of

Boswellic acid and Guggulsterones from gel was performed to study the release behavior of

drug from formulation From the observed results it was concluded that there is increase in

the drug release with respect to time From a patient compliance point of view spreadability

is a important for topical drug delivery system The gel was found to exhibit good percentage

spread by weight that would assure the skin application Anti-Inflammatory Anti-Arthritic

study and Arthritis scoring of the prepared gel formulation evident the Anti-Arthritic activity

of the prepared herbal gel formulation Temperature stability study was performed to evaluate

the separation as well as precipitation of the drug in the excipients mixture It was observed

that the formulation was stable at different temperatures (room temperature cool

temperature elevated temperature and at 75 RH) for 60 days

In the present work the attempt was made to formulate and evaluate a gel for anti-arthritic

activity using extracts of Boswellia serrata and Commiphora mukul The results showed that

the content of Gel components had significant effect on their physical rheological and in

vitro drug release characteristics
