Scavenging activity of AVTE toward 1,1-diphenyl-2-picrylhydrazyl radical (DPPH), hydroxyl radicals (OH), 2,2′-azino-bis (3-ethylbenzthiazoline-6-sulphonic acid) diammonium salt radicals (ABTS), and superoxide anion. (a) DPPH radical; (b) OH radical; (c) ABTS radical; and (d) superoxide anion radical. Ascorbic acid was used as positive control in antioxidant experiments. ^a–d Mean values with different letters in the same bar graph are significantly different () according to Duncan’s multiple range test.
