In vitro Antioxidant Activity of Delonix elata L

Antioxidant activity of ethanolic extract of Delonix elata L.was studied for its free radical scavenging property on different in vitro models e.g 1, 1-dipheny 1-2-picryl hydrazine (DPPH), hydrogen peroxide, total antioxidant capacity and peroxy radical model. The in vitro lipid peroxidation (LPO) was inhibited to a good extent by the ethanolic leaf extract of Delonix elata L. The extract showed good dose – dependent free radical scavenging property and antioxidant property when compared to standards. In all the models, the results obtained in the present study indicate that the leaves of D.elata L. are a potential source of natural antioxidant.
