The present study is aimed to estimate the total phenolic and flavonoid content and to evaluate the antioxidant property by deoxy ribose assay for detecting the hydroxyl radical scavenging property using ascorbic acid as the standard. Antiinflammatory study was estimated by HRBC method. The hydroxyl scavenging activity of the ethanolic tuber extract of Dioscorea bulbifera Linn tuber was evaluated and it was found to be potent when compared with the standard ascorbic acid. The total phenolic content was found to be 77mg/g of extract calculated as gallic acid equivalent and total flavonoids as 29mg/g of extract as rutin equivalent. The ethanolic extract of tuber at a concentration of 250µg/ml shown potent anti inflammatory activity on comparison with standard drug Diclofenac Sodium.
