FIELD OF THE INVENTION
The present therapy for RA involve nonsteroidal anti-inflammatory drugs corticosteroids, disease modifying anti-rheumatic drugs and some recently developed biologic agents, but all of these are linked with side effects. The present invention relates to a composition for the treatment of Rheumatoidarthritis comprising Alpha Pinene isolated from Boswellia serrata extract and pharmaceutical excipient. Moreover, it also relates to a method for extracting Alpha Pinene compound from Boswellia serrata.
BACK GROUND OF INVENTION
Rheumatoidarthritis(RA)isanautoimmuneallergicconditioncausesongoinginflammationandsynovial fibroblast proliferation, which leads to the permanent loss of articular cartilage and bonebroughtonbyatherosclerosis[YanagisawaSetal.,2022].TheprimarycauseofRAisinflammation-induced loss of articular cartilage, however the exact mechanism is yet unknown.Thesamemightcausesymptomssuchasjointpainandswelling,stiffnessinthejoints,insomnia,exhaustion,weightloss,andflu-likesymptoms[AnjanaGoel1andSunandaKulshrestha,2021].As aresult,challengeswithdaily tasks includingdressing,grooming,walking, and cooking are frequent. Additionally, discomfort and exhaustion can make it difficulttoworkandfrequentlyhaveabadimpactonsociallife[TuressonWadellAetal.,2021].
Worldwide, the prevalence of RA ranges from 0.5 to 1% ofthe population, and in the case of the Indian population, more than 20%of the population hasanyformofarthritis[LinYen-Juetal.,2020].Comparedtomen(2%),women(4%)encounteritmore frequently. More over 50% of RA patients in wealthy nations stopped working full-timewithin ten years after the disease's inception. Every year, 41 out of every 100,000 people receivea RA diagnosis, and 1.3 million Americans have the disease. Diagnoses for the condition can bemade anytime between three months after the commencement of the illness and even after twoyearslater,whenithasbecomemoresevere[ChandoAnitaetal., 2021].
RA patients typicallyneedanalgesic and anti-inflammatorymedications (NSAIDs)totreatillnesssymptoms [PagliaMDGetal.,2021]. The leadingfactorcontributingtoincreasedmortalityinRAiscardiovasculardisease(CVD),primarilybroughtonbyatherosclerosis[DeyabG et al., 2021]. RA is very different from osteoarthritis, a degenerative joint condition that solelyaffects joint function and also link to number of body
functions as such gastrointestinal issues,renal dysfunction, and an elevated risk of cardiovascular disease [Kumar Janakiraman et al.,2018].
Nonsteroidalanti-inflammatorymedicines(NSAIDs),steroids,disease-modifyinganti-rheumaticmedications (DMARDs) and glucocorticoids are the main pharmacological classes of drugs usedto treat RA. These medications can only slow the RA's progression, which raises the danger ofinfection.Theprolongeduseofthesetreatmentswillresultindrugdependenceandastringnegative side effect, including rashes, liver damage and hair loss [Zhihao Zeng et al., 2021]. Inthis autoimmune illness, a number of immunological processes are carried out simultaneouslyandthesynoviumfoundalsoplaysacrucialroleintheseprocesses.AcuteinflammationinRAischaracterised by synoviocyte activation and proliferation, which results in the generation ofcytokines and proteases. Pro-inflammatory cytokines like TNF-, IL-6, and IL-1 are produced bysynoviocytes that resemble macrophages,whereas fibroblast-like synoviocytes are primarilyresponsible for producing IL-6, proteolytic enzyme (MMPs), prostaglandins, and leukotrienes.[Gurleen Kour et al., 2021]. Invasion of the synovium damages bone and cartilage. Additionally,T cells, ß cells and adaptive immune cells infiltrate the synovium as a result of RA. Rheumatoidfactors and ACPAs are produced by ß cells, which also serve as cells that deliver antigen andhelpstoactivateTlymphocytes[ArzooPannuetal.,2019].Numerousimmune-mediatedsubstances canpromoteinflammationinsynovialjoints.[AdityaSetal.,2016].Themostprevalent kinds of arthritis are gout, juvenile idiopathic arthritis, reactive arthritis, psoriaticarthritis,rheumatoidarthritis,septicarthritis,andankylosingspondylitis[JainSetal.,2021].
The diagnosis of RA is made using clinical imaging methods and laboratory examinations.Testableconditionsinlaboratoriesincludeanaemia,thepresenceofrheumatoidfactor,antibodiesagainstcycliccitrullinatedpeptides,andanincreaseinerythrocytesedimentationrate.Whilethecondition'ssymptoms,suchaspersistentmorningstiffnessandsoreness,providesomedetailsabout it.EventhoughtheyhelpinRAidentification[YanagisawaS etal.,2022].
Tablets, capsules, oral liquids, topical treatments, parenterals, paediatric/geriatric medicines, andtransdermal patches are only a few of the standard dose forms used to treat RA [Aisha Mobasharet al., 2020]. Ointment, cream, gels, and paste are examples of topical dose forms forthetreatmentofRA[JurcaTetal.,2021].Transdermalpatchesaretheadvancedformattinga

Poorpatient compliance, a brief half-life (t/2), low bioavailability, and poor solubility were the maindements with conventional dosage forms used to treat RA. These issues may be resolved bydevelopingnewdosageformsexamplemicroparticles,nanoparticles,nanoemulsions,nanomicelles,nanodispersions,nanocapsules,nanosuspensions[JanakiramanKet al., 2018].
Boswellia serrata commonly known as Indian frankincense tree, belongs to Burseraceae family,holdingbothtreesandshrubsoftropicalandsubtropicalgeographicaldistribution,withapproximately 700 species originating from 18 genera [Upaganlawar A. and Ghule B. et al.,2014]. The genus Boswellia was named in an honour of Johann Boswell (1719-80) who hasdescribed 25 species of Boswellia; some of them, however, appear now as synonyms of the 21known species. The genus Boswelliahas mostly found in Africa (Sudan, Eritrea, Ethiopia,Somalia, and Kenya), southern Arabia (Oman and Yemen), and India [Pawankumar Rai, 2019].In India, Boswellia serrata mainly established in the region of the States of Andhra Pradesh,Gujarat, Madhya Pradesh, Jharkhand and Chhattisgarh. Boswellia serrata has also shown theability to inhibit pro-inflammatorycytokines. Itsuppresses interleukin-1ß(IL-1ß), tumornecrosisfactor-a(TNF-a),interferon-?(IFN-?),and enhances productionIL-10in arthritisinduced rats. These cytokines have a crucial role in chronic inflammation and tissue damageduringtheprogression ofRA[KumarRetal.,2019].
Pinene (C10H16) is a bicyclic, double bond, terpenoid hydrocarbon. a- and ß-pinene are twoisomers found in nature, e.g., in pine (coniferous trees) essential oils (EOs). They are among thebest-known representativesofabroadfamilyofmonoterpenes.a-andß-pineneenantiomersaredifferent in their interactions with polarized light, and their mirror image does not overlap. Bothstructural isomers have two enantiomers (+) and (-). This difference yields four active isomers.a-pinene is a colorless, water-insoluble but oil- and ethanol-soluble organic liquid. Its boilingpoint is 155 °C. a-pinene has been detected in at least 40 different EOs. ß-pinene is also acolorless organic liquid which is oil-soluble but ethanol- and water-insoluble. It has a boilingpoint rangingfrom 163–166 °C. It is obtained commercially by distillation or by a-pineneconversion[SalehiB.etal.,2019].

The problem is Rheumatoid arthritis. These problem is increasing rapidly in day todays life, and becoming very serious during the days. These invention work on anti-arthritic activity. The herbal constituent alpha-pinene used to treate arthritis. It is found that alpha-pinene exhibits anti-inflammatory activity through the suppression of Mitogen-activated protein kinases (MAPKs) and the nuclear factor-kappa B (NF-?B) pathway in mouse peritoneal macrophages. Many different plants and different constituents were used to treated arthritis. The main disadvantage is slow action.The constituent alpha-pinene is new to be used in invention. Alpha-pinene exhibits anti-inflammatory activity through the suppression of Mitogen-activated protein kinases (MAPKs) and the nuclear factor-kappa B (NF-?B) pathway in mouse peritoneal macrophages.
The present study aims to provide scientific evidence regarding the anti-arthritic activity of alphapinene,whichisderivedfromBoswelliaserrata.Byquantifyingandidentifyingthebioactiveconstituent and conducting pharmacological evaluations, the study aims to contribute to theunderstanding of the potential therapeutic benefits of this compound in the management ofarthritis.
SUMMARY:
Rheumatoid arthritis (RA) is a severe autoimmune condition that causes persistent joint inflammation that increases the risk of early death. It is with almost 0.3% to 1% worldwide prevalence. Compared to males, women are three times more likely to be impacted by RA in the ratio of 3:1. The present therapy for RA involve nonsteroidal anti-inflammatory drugs corticosteroids, disease modifying anti-rheumatic drugs and some recently developed biologic agents, but all of these are linked with side effects. Herbal medicines are more accepted with the opinion that they are safer and have less adverse effects than synthetic ones. Phytochemicals of herbal medicines are particularly useful in the management of arthritis additional to being highly beneficial in the treatment of inflammatory, autoimmune and infectious disorders. One of the main causes of disability for millions of individuals worldwide is arthritis. Some of the phytoconstituents of herbal drugs, of Boswellia serrata have been reported to have anti-inflammatory activity. The utilisation of biologically active molecules derived from plants is used to treat autoimmune diseases like rheumatoid arthritis (RA) and the pharmacological effects of phytochemicals have long been known. The plant Boswellia serrata commonly known as "Salai Guggal," this species is significant and useful in many different ways and mostly to be more effective for arthritis. The plant's most active component that helps treat rheumatoid arthritis is “Alpha pinene”, it is extracted from its leaf using the percolation process.

a. Coarsely powdered drug material: The plant material such as leaves is ground into a coarsepowder.Thisincreasesthesurfaceareaofthematerial,facilitatingefficientextraction.
b. Placingthedrugmaterialinacontainer:Thepowderedplantmaterialisplacedinsideacontainer.The container should be large enough to accommodate the material and leave space for thesolvent.So, 200gofpowderwassuccessivelyextractedwith2L ofsolvent.
c. Adding the menstruum: The menstruum which is the solvent used for extraction, is poured ontothe powdered drug material to cover it. The choice of menstruum depends on the properties of thedesiredcompoundsandthesolubilityoftheplantconstituents.
d. Closingthecontainer:Thecontainerissealedorclosedtopreventevaporationandcontamination.Thisallowstheextractionprocesstoproceedundisturbed.
e. Allowing extraction to occur: The closed container with the drug material and menstruum is keptfor at least three days. During this time, the active constituents of the plant material dissolve intothesolvent.
f. Stirring or shaking: Periodically, the contents of the container are stirred or, if the extraction isperformed in a bottle, shaken. This ensures thorough mixing of the solvent and plant material,enhancingtheextractionefficiency.
g. Separating the micelle from the marc: After the extraction period, the mixture is separated intotwo components. The micelle refers to the solvent (containing the dissolved compounds) alongwithanysuspendedsolidsorplantdebris.Themarcreferstotheleftoverplantmaterial.
h. Filtrationordecantation:Themicelleisseparatedfromthemarcbyeitherfiltrationordecantation. Filtration involves passing the mixture through a filter to collect the liquid fractionwhile leaving behind the solid material. Decantation involves carefully pouring off the liquidportionwhileleavingthesedimentatthebottomundisturbed.
i. Separating the micelle from the menstruum: The micelle, containing the desired compounds, isthen separated from the menstruum that was used for extraction. This separation is typicallyachieved through evaporation. The micelle can be evaporated in an oven or on top of a waterbath, allowing the solvent to evaporate and leaving behind the concentrated extract. After dryingrespectiveresidueswereweighedandpercentageyieldwascalculated.
Thepercentageyieldofextractswascalculatedbyusingfollowingformula:
%yield= (Weightofextract/ Weightofpowderdrug) X 100
The percentage yield is 150%. This means that the extraction process yielded 3 gramsofextractfrom2grams ofthepowdereddrug,whichis150%oftheinitialamountofthepowder used.

TheprocedureforTLCinvolvesthefollowingsteps:
o PreparationofTLCplate:TLCplatesusedarealuminumTLCplatecoatedwithsilicagel.Themostcommon adsorbent is silica gel. Before starting the experiment, maked sure that TLC plates arecleanand freefromanycontaminants.
o Preparing the sample: Dissolve the extractwith solvent methanol and 10µl concentration wasprepared andmixture containing the compounds (alpha-pinene)want toseparate in a suitablesolventand the drug alpha-pinene dissolve with solvent methanol 10µl concentration was preparedfor comparative study. Use a small amount of the sample (usually in the microliter range) to spot itontheTLCplate.Spotscanbeapplied usingamicrosyringe.
o Developing the TLC plate: Pour asmall amount of the mobile phase (Toluene: Ethyl acetate(85:15)) into a developing chamber, which is a closed container. Place the TLC plate inside thechamber, ensuring that the solvent level is below the spot line. The mobile phase will ascendthrough the plate by capillary action, carrying the sample components with it. Allowing the solventtotravelacertaindistanceuptheplate,usuallyabouttwo-thirdsofthetotal platelength.
o Visualization of spots: Removed the TLC plate from the developing chamber once the solventreached to the highest point on the plate to the top of the plate. Marking the solvent front with apencil or a line. Quickly visualize the separated spots by using ultraviolet (UV) light by staining theplatewithdilutedsulphuricacid(dil.H2SO4),5%chemical.
o Calculation of Rf values: The phrases ultra-violet light (254 nm) and ultra-violet light (366 nm)indicate that the plate should be examined under an ultra-violet light having a maximum output atabout 254 or at about 366 nm. After the spots are visualized, measure the distance traveled by eachextractcompoundspotfromthestartinglineandthedistancetraveledbythedrugalpha-pinene.front from the starting line. The Rf value (retention factor) for each compound is calculated as theratio of the distance traveled by the extract spot to the distance traveled by the drug alpha-pinenefront.
o Rf=Distancetraveledbythecompoundspot/Distancetraveledbythesolventfront
o Interpretation of results: Compare the Rf values obtained for the spots on the TLC plate with thoseofknowncompounds(alpha-pinene)underthesameexperimentalconditions.Rfvaluesarecharacteristic for different compounds under specific TLC conditions and can be used to identifycompoundalpha-pinenein theextract.
It's essential to handle TLC plates with care and use appropriate safety measures, especially whenworking with potentially hazardous substances or solvents. It is important to choice the adsorbent,mobile phase, and visualization method which significantly impact the separation and identification ofcompoundsinTLC. In TLC, the resolution factor (Rf) value is a quantitative measure used to evaluate the separationofdifferentcompoundsonaTLCplate.Itiscalculatedastheratioofthedistancetraveledbythecompoundspot(center)tothedistancetraveledbythesolventfront(eluent)fromtheorigin (figure 2 and 3).TheRfvalueis0.45,itmeansthatthecompoundinquestiontraveled0.45timesthedistancecoveredbythesolventfrontin theTLCexperiment. TheRfvalueof 0.45suggests thatthecompoundhadmoderateretentionontheTLCplate,meaningitmovedslowerthanthesolventbutnotsignificantly slow.
Using High performance liquid chromatography (HPLC): HPLC is a versatile separation technique with wide range of application, the process is sometimescritical due to its large number of variables, which need to be properly adjusted before every single run.HPLC separation of each chemical entity from the sample mixture is based on its distinct affinitytowards the adsorbent material in the column or the mobile phase, causing various constituents to travelatdifferentvelocitiesandseparate.Itwasformerlycalledashigh-pressureliquidchromatographysince;it relies on high pressure pumps to allow quicker separation.Separation by HPLC predominantlydepends on some intrinsic tunable parameters of mobile phase like polarity, flow rate, pH, compositionand some inherent properties of sample matrix; type and nature of stationary phase; environmentalfactors like temperature and detectortype andsettings.New HPLCmethodwas developed andvalidatedaccordingtoICHguidelinestoanalyzesevenmajorchemicalconstituents.ThismethodisoneofthealternativemethodsforLC-MEmethod.
HPLC Method was performed on a PEAK chromatographic system equipped with LC-P7000 isocraticpump; injector with 20µl fixed volume loop, separation was achieved on C18 column (4.6 mm × 250mm i.d., 5 µm) and at a column temperature of 25°C; with UV-Visible detector and the output signalwas monitored and integrated by PEAK Chromatographic Software used is double beam UV-Visiblespectrophotometerwasusedtocarryoutspectralanalysisandthedatawasrecordedbysoftware. Sonicator was used to sonicating the mobile phase and samples up to 20 min., pH of the mobile phasewasadjustedwithglacialaceticacid. Themobilephasewasusedasdiluents.
High-Performance Liquid Chromatography (HPLC) is a powerful analytical technique used to separate,identify,andquantifycomponentsinamixture.Here’stheprocedureofanHPLC:
Sample preparation: Prepare the sample to be analyzed. This may involve dissolving the sample(extract of B. serrata and standard solution of alpha-pinene) in an appropriate solvent (methanol)and10µgofextractandstandardsolutionwerepreparedandfilteringittoremoveanyparticulatesthatcouldclog theHPLCcolumn.
HPLC system setup: Turn on the HPLC instrument and ensure that it is properly connected andallcomponents(pump, injector, column, detector)arefunctioningcorrectly.
Prime the HPLC system with the mobile phase to remove any air bubbles and ensure a steadyflow.
Columnselection:ChooseanappropriateHPLCcolumn(C18column)basedonthenatureoftheanalytes and the desired separation. Columns with different stationary phases and dimensions((4.6mm×250mmi.d.,5µm))areavailableforspecificapplications.
Mobile phase selection: Select an appropriate mobile phase based on the solubility and chemicalproperties of the sample components. The mobile phase may consist of a single solvent (isocraticelution) oramixtureofsolvents(gradientelution) dependingontheseparationneeds.
o Calibrationandstandardsolutions(ifquantitativeanalysisisrequired):Preparestandardsolutions of 10µl of known concentrations to calibrate the HPLC system and create a calibrationcurveforquantification.

The major peak observed at 3.305 minutes in the Boswellia serrata extract chromatogram mightcorrespond to alpha-pinene, considering it has a very close retention time to the standard (3.312minutes). The second major peak at 4.195 minutes could be another component present in theBoswelliaserrataextract.
Confirmation of alpha-pinene: The presence of alpha-pinene in the Boswellia serrataextract is supported by the fact that the retention time (3.305 minutes) of one of the major peaksin the chromatogram closely matches the retention time (3.312 minutes) of the alpha-pinenestandard..TheHPLCpeakobservedatthespecificretentiontimeinboththeHPLCchromatogramofthe extract and the standard corresponds to alpha-pinene, providing evidence of its presence in thesample.

The experiments carried out using Albino rats weighing between 150 g and 250 g (CentralAnimal House, GD Goenka, Registration no. 2127/PO/ReRcBi/S/21/CPCSEA). The albino ratswill divide into five groups, i.e. control, standard, negative control and drug treated (two groupsof drug treated low and high dose treated group). Rats will inject with 0.1 ml of Freund'scomplete adjuvant (CFA) into the planter region of the left hind paw. The paw volumes of boththe hind paws will measure using a vernier caliper and body weight will record on the day ofadjuvant injection. The solvent-drug extract of the aerial parts of the plant (0.5 and 1 mg/kg)and diclofenac sodium (10 mg/kg) doses will administer intra-peritoneal for 14 days from theday of CFA injection. The changes in the paw volume will be measure on various days up to
21days following CFA injection. The change in the inflammatory reaction will measure by usingvernier caliper on 0th, 7th, 14th and 21st day from the day of adjuvant injection. The animalswill weigh, using digital weighing balance on 0th, 7th, 14th and 21st day from the day of CFAinjection. At the end of experiment, on the 21st day all animals will be anaesthetize (Diethylether)andbloodwilldrawnbyretro-orbitalplexusesbypunctureandcollectinEDTAcontainingtubes,respectively.Bloodanalysis,biochemicalparameteri.e.,RBC,WBC,Platelet,Hb,andhistopathologicalparameterswillbedetermined.
