Antioxidants prevents oxidative damage caused by free radicals and can be used in cardiovascular and anti-inflammatory diseases. The presence of natural antioxidants in plants is well known. The present study is undertaken to evaluate the phytochemical constituents, total phenol, total flavonoid and anti-oxidant activity of the plant Peltophorum pterocarpum. The extracts of leaves of P. pterocarpumcontains terpenoids, flavanoids, steroids, phenols, cardioglycosides, quinines, coumarins and tannins. Presence of these phytochemicals have ability for curing various ailments and possess potential anti-inflammatory, antimicrobial and antioxidant activities. The in-vitro antioxidant activity was determined by the method of DPPH radical scavenging assay. The result shows that ethanolic extract of P. pterocarpumleaves had highest antioxidant activity (94%) using DPPH method. Thus the in-vitro studies clearly indicate that the leaves extract of P. pterocarpumshows significant antioxidant activity which would be helpful in prevention of various oxidative stresses.
