ANTIOXIDANT ACTIVITY OF PLANTS AT CHINNATIRUPATHI, SALEM, TAMIL NADU, INDIAAbstract
This study was carried out during March – April 2013. The fresh leaves collected were extracted with water and used for antioxidant assay. Nitric oxide scavenging activity, Reducing power assay, Metal chelating activity, Phosphomolybdenum activity was assayed and also secondary metabolites such as phenol, flavonoid was estimated. These metabolites play a major role in antioxidant activity. Here, the flavonoid content was found to be more in most of the plants selected thus having significant total antioxidant activity. Likewise, total antioxidant, metal chelating activity was high with Nerium oleander, whereas all the other plant showed moderate amount of antioxidant activity. But the phenol content was low in selected plants.
