ABSTRACT
The aim of present investigation was to evaluate anti-rheumatic
activity of two herbs (Commiphora mukul and Boswellia serrata) and
to formulate a topical gel dosage form Boswellia serrata dry extract
65 was collected from the Konark Herbals and Health Care and
Commiphora mukul dry resin was collected from Local Market
Nagpur The evaluation of crude drug and the re-successive solvent
extraction of resin was carried out Development of gel was done by
using carbapol 934 and PEG 400 From the result of preliminary
phytochemical screening of extract it was observed that the fractional
product of Commiphora mukul resin contained triterpenoids and
sterols The result obtained from present work indicated that the entire
drug was uniformly distributed and there was no precipitation in
formulation It was observed that the formulation was stable at
different temperatures and exhibit good percentage spread by weight that would assure the
skin application From the present work it was concluded that it is possible to formulate the
herbal gel for anti-arthritic activity by using Commiphora mukul and Boswellia serrata The
results showed that the content of Gel components had significant effect on their physical
rheological and in vitro drug release characterization

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

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

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

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

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

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

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

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

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
Anti ndash Inflammatory and anti-arthritic is common use

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

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

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

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

2 MATERIAL AND METHOD
Material used
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

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

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

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

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

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

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
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

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

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

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

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

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

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

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
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

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

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

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

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

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)

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

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)

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

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

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

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

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

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

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
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

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

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

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

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

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
Spreadability = mlt

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

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

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
Spreadability = mlt

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

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

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

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

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

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

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

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

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

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

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
