The present study is to evaluate a systemic record of the relative antioxidant activity of Triumfetta pilosa .The ethanolic extract of Triumfetta pilosa was screened for their free radical, hydroxy radical, superoxide & nitric oxide scavenging activity. Total antioxidant activities of ethanolic extract were compared with standard antioxidants ascorbic acid, copper sulphate 2, 6- di-ter-butyl-p-hydroxytoluene (BHT). Results indicate the ethanolic extract exhibited antioxidant potential of invitro screening methods .The results indicate that ethanolic extract showed moderate activity against standard drugs.
