The objective of this study was to investigate the antioxidative capacity of Prunus avium 95% ethanol extracts. Total antioxidant status was examined by total antioxidant capacity against ABTS radical reactions. Total antioxidant capacities of P. avium extract at the concentrations of 0.2 and 1 mg/mL were 0.33 and 2.26 mM Trolox equivalents, respectively. Superoxide scavenging activities of P. avium extract at the concentrations of 0.2 and 1 mg/mL were 45.0 and 77.0%, respectively. Oxygen radical absorbance capacities of P. avium extract at the concentrations of 5 and 100 μg/mL were 40.88 and 131.00 μM Trolox equivalents, respectively. Thus, strong antioxidant effects of P. avium extract seem to be due to, at least in part, the prevention from free radicals-induced oxidation as well as high levels in total phenolic contents.
