Conc., concentration; AAE, ascorbic acid equivalent; TE, Trolox equivalent; GAE, gallic acid equivalent; CE, catechin equivalent.
All values are mean±SD (n=3).
Different superscript letters (^a-f) within a column indicate significant differences by one-way ANOVA with Duncan’s multiple range test (p<0.05).
