Present study is based on comparison of antioxidant potential and related phytochemicals present in leaves and flowers extracts of Erythrina suberosa. Results indicate that different extracts of flowers and leaves (Crude/Methanol, Hexane and Water) show good antioxidant potential in all assays. In DPPH radical de-colourization assay crude extract of flowers found most active with IC50 value 49.00 µg/ml while aqueous extract showed lowest potential (IC50, 193.40 µg/ml). On the other hand maximum ability to scavenge ABTS radicals was possessed by aqueous leaves extract (IC50, 09.40 µg/ml) and least by hexane extract of leaves (IC50, 37.20 µg/ml) other have intermediate potential in both assays. Comparison of Total antioxidant capacity and anti-lipid peroxidation, aqueous leaves extract and crude extract of flowers has shown maximum potential respectively in these assays. Overall, high antioxidant potential as well as total phenolic contents were possessed by different flowers extracts.
