Antioxidants are an inhibitor of the process of oxidation, even at relatively small concentration and thus have diverse physiological role in the body. The present study was carried out to identify the phytochemicals and evaluate antioxidant activity of chloroform extract of Delonix regia leaves. The antioxidant activity was determined by different methods via DPPH radical scavenging assay, Hydrogen peroxide scavenging assay and reducing power assay. The leaves of chloroform extract contain terpenoids, steroids, flavonoids and Tannins. The antioxidant activity found in DPPH method is more effective than other two methods. Thus the in-vitro studies clearly indicate that the chloroform extract of Delonix regia leaves shows significant antioxidant activity and also a better source of natural antioxidant, which might be helpful in preventing the process of various oxidative stresses
