Persimmon leaf powder (mg)/ water (1 mL).
AAE, ascorbic acid equivalent; TE, trolox equivalent; GAE, gallic acid equivalent; CE, catechin equivalent.
Each value represents mean±SD (n=5).
Different superscripts within a column indicate significant differences (one-way ANOVA followed by the Duncan’s multiple range test, p<0.05).
