Data are expressed as mean + Standard Deviation (SD) (n = 3). Mean values within a column with different abc superscript letters represent significant differences (p < 0.05). IC: Inhibition concentration; DPPH: 2, 2-diphenyl-1-picrylhydrazyl; ABTS: 2, 2′-azinobis-3-ethylbenzothiazoline-6-sulfonic acid, AAE: Ascorbic acid equivalent antioxidant capacity; TEAC: Trolox equivalent antioxidant capacity.
