Abstract : The present study was undertaken to know about the free radical scavenging activity of plants located near Thermal power plant, Mettur, Salem. In this study, Polyalthia longifolia, Derris indica, Holopetela integrifolia, Tamarindus indica, Terminalia tomentosa, Psidium guajava, Nerium indicum, Azadirachta indica, Calotropis gigantea, Ricinus communis, Carica papaya, Ficus benghalensis, Embilica officinalis, Tectona grandis, Ficus religosa, Mangifera indica, Moringa oleifera, Acacia Arabica, Opuntia ficus indica are the plants that were collected during March to April 2013. Among the plants selected, Holopetela integrifolia, Mangifera indica, Tamarindus indica, Acacia arabica, Azadirachta indica were found to have high flavonoid content. Total antioxidant activity was measured in terms of phospho-molybdenum activity was high in Carica papaya when compared to the other entire antioxidant assay, Acacia arabica showed maximum ability to chelate metal ions.
