Mangroves have long been used in fisherman for traditional folk medicine to treat many diseases, however till date; these plant species have been not tested scientifically to validate their traditional uses. Hence our present studies to test antioxidant capacity of selected mangrove plants in picahvaram mangrove forest. Antioxidant activity of defatted Methanol extract of some mangrove plant leaves were studied for its free radical scavenging property on different In vitro models. 1, 1-diphenyl-2 picryl hydrazyl (DPPH), Superoxide and total phenolic content were analyzed. The extracts showed good dose dependent free radical scavenging property in all samples. In this model high SOD and radical scavenging value indicated in, Excoecaria agallocha and low SOD and radical scavenging value was indicated in Avicennia marina Although the highest total phenolic content was found in Rhizophora mucronata extract, and low activity fund in Avicennia marina there is no positive correlation between evaluated antioxidant activities and the phenolic contents of examined the Pichavaram mangrove plants. The results clearly confirmed the antioxidative and free radical scavenging activity of the extract.  In our feature study identification of the antioxidative constituents of the plants and evaluation of their probable anti-diabetic, anti-cancer and cardiac vascular disease   properties is in progress.
