Antioxidant and free radical scavenging activities of Indian acacias: Acacia leucophloea (Roxb.) willd., Acacia ferruginea dc., Acacia dealbata link. and Acacia pennata (l.) willd

Abstract

The acetone and methanol extracts of barks of A. leucophloea, A. ferruginea, A. dealbata, and A. pennata were evaluated for their total phenolics and flavonoid contents and antioxidative activities. Acetone extracts of barks exhibited higher contents of total phenolics and flavonoids. Further, the acetone extracts showed higher activity in DPPH•, ABTS •+, and OH•; FRAP; metal chelation; phosphomolybdenum reduction; and peroxidation inhibition. In conclusion, the results implied that the barks could be considered as health supplements and nutraceuticals/functional foods. © 2013 Copyright Taylor and Francis Group, LLC.
