In vitro Evaluation of Tephrosia purpurea Pers for Antioxidant Activity

This research was taken up to investigate the antioxidant activity of leaves of Tephrosia purpurea. The in vitro antioxidant activity of ethanolic extract of leaves of Tephrosia purpurea was investigated by DPPH free radical scavenging, and nitric oxide scavenging methods. The ethanol extract showed good antioxidant activity in these above methods. This activity may be due to the presence of flavanoids.
