Abstract: Antioxidants act on free radical species by inhibiting their formation, converting them into less harmful molecules and thus prevent chain reactions that are injurious to cells. Therefore the need for the search of antioxidants from natural origin has been greatly felt in the recent years. The present study aimed to investigate the antioxidant activity in Polyclinum madrasensis extracts by methods like DPPH, Hydroxyl, ABTS, superoxide radical scavenging activity, and reducing power using in vitro models. In DPPH and ABTS radical scavenging activity methanol extract (146.26, 142.16) showed higher percentage of inhibition. Whereas, ethanol extract was found to be higher in hydroxyl (119.14) and reducing power. In superoxide radical scavenging activity ethyl acetate extract (113.46) was higher
