Plant has an innate ability to produce non-enzymatic antioxidants which have an important role in the metabolism of Reactive oxygen species (ROS). Several plants serve as the source of therapeutic agents but the properties depend on the plant nature. Thus, an evaluation of antioxidant activity is essential to determine the importance of a plant. Three plants Utleria salicifolia, Plectranthus vettiveroides and Nothapodytes nimmoniana were selected to carry out the antioxidant study. Methanol assisted leaves extracts were prepared and subjected to antioxidant assay by means of DPPH radical scavenging assay, Metal ion Chelating Assay, Superoxide Anion Radical Scavenging Assay and Hydroxyl radical scavenging assay. All the extracts showed 20-80% inhibition depending on the concentration of extracts and the type of assay as well. The existence of crucial organic compounds in the leaf extracts of all the three plants were corroborated by Gas chromatography analysis. The present results offer supporting evidence for effective use of selected plant extracts.
