Radical Scavenging and Antioxidant Potential of Nuts and Leaves Extracts of Semecarpus anacardium (L.)

Abstract

In the present investigation, antioxidant activity of the crude extracts from nuts and leaves of S. anacardium was carried out. The antioxidant potential of various extracts (ethanol, acetone and aqueous) of S. anacardium was determined by using DPPH assay, ABTS assay and metal chelating activity assay. Among the extracts the ethanol extract of nut showed significant scavenging activity (DPPH-88.73 ± 2.26; ABTS assay-81.65 ± 1.57 and metal chelating activity-72.37 ± 2.26) compared with antioxidant controls, ascorbic acid and BHA respectively. The findings of the present investigation suggest that the S. anacardium extracts can prove to be a potent source of biologically active compounds that can be further subjected to isolation of therapeutic antioxidant agents.
