Abstract

Tribulus terrestris L. and Eclipta alba L. are commonly used plants in Indian folklore medicine. The present study investigates the antioxidant potential of ethanolic extract of the fruits of Tribulus terrestris and the methanolic extract of the aerial parts of Eclipta alba. They were investigated for hydroxyl radical and 1,1-diphenyl-2-picrylhydrazyl (DPPH) stable free radical scavenging activity and for inhibition of lipid peroxidation. It was found that both the extracts exhibited significant free radical scavenging capacity for DPPH and for hydroxyl radical. Further, the extracts showed considerable inhibition of lipid peroxidation.

Keywords: Tribulus terrestris; Eclipta alba; antioxidant activity; free radicals; lipid peroxidation
