Background:Oroxylum indicum\ (Bignoniaceae) also known as Sonapatha is an indigenous medicinal plant widely used in Ayurvedic medicine for over thousands of years. It is an active ingredient of well-known Ayurvedic formulations such as Chyawanprash and Dasamula. Root bark of this plant has tonic and astringent properties and it is also used in rheumatism.\ Objective:\ The present investigation was carried out to evaluate the anti-arthritic activity of different extracts of root bark of\ Oroxylum indicum\ against adjuvant - induced arthritis in rats.\ Materials and Methods:\ Male Wistar rats were used in this study. Arthritis was induced by injecting 0.1 ml Freund{\textquoteright}s complete adjuvant intra-dermally into the left hind paw of the rats. The paw volume, hematological, biochemical, radiographic and histopathological aspects were evaluated.\ Results:\ The relative percentage inhibition potential of paw volume in rats treated with various extracts of\ Oroxylum indicum\ was found to be ethyl acetate extract (67.69\%) \>chloroform extract (64.61\%) \>n-butanol extract (58.46\%) respectively. The hematological parameters like RBC count, hemoglobin content showed significant increase while there was a significant decrease in total WBC count and ESR in all the groups of animals pretreated with root bark extracts. The biochemical parameters such as catalase, glutathione contents showed a significant increase while the lipid peroxide and Cathepsin-D content decreased significantly only in case of ethyl acetate pretreated rats when compared to others.\ Conclusion:\ The present study suggests that the chloroform, ethyl acetate and n-butanol extracts of root bark of\ Oroxylum indicum\ exhibit anti-arthritic activity. The order of activity of extracts was found to be ethyl acetate \>chloroform \>n-butanol respectively.
