Antioxidant capabilities of PRE and punicalagin alone and in combination with 28.76 μg/mL (0.1 mM) Zn (II). (a) % DPPH antioxidant scavenging capacities at different sample concentrations. (b) TEAC values obtained for each sample, based on the finding of the ABTS assay. Values are presented as the mean ± SEM (n = 3). TEAC, Trolox equivalent antioxidant capacity. Values followed by the same capital letter within the same column are not significantly different (p > 0.05) between the compounds analyzed by Duncan’s multiple range test. * ND; not determined.
