The antioxidant capacity of Bauhinia purpurea stems bark extracts, obtained by sequential extraction with various polarities of solvents, by hot continuous percolation method. The antioxidant properties of different crude extracts were evaluated using different antioxidant tests such as free radical scavenging activity, metal chelating activity, superoxide anion scavenging assay, total antioxidant activity, and reducing power for comparison. In addition, total phenolic
and flavonoid compounds in the extracts were determined as catechin equivalent. The various antioxidant activities were compared to standard antioxidant such as ascorbic acid. From the tested Bauhinia purpurea crude extracts showed potent different level of in vitro antioxidant activity. Results indicate the possible potential use of medicinal plant Bauhinia purpurea indicate that it may be a potential source of natural antioxidant
