| 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. |
