Extract from the leaves of Tylophora asthmatica were investigated for antioxidant activity. The methanolic extract of T.asthmatica had a DPPH scavenging activity of 84.6% at 250µg/ml and a reductive potential of 0.77 at 100µg/ml. These values were comparable with those of Gallic acid, 91.4% at 250µg/ml and Ascorbic acid, 0.79 at 60µg/ml as standards for DPPH scavenging activity and reductive potential, respectively. These findings suggest that the rich phytochemical content of T.asthmatica and its good antioxidant activity may be responsible for its popular and wide traditional use. The experiment was carried out with the leaves of the selected medicinal plants. The results are discussed with the available literature.
