This study was conducted to investigate the antioxidant compounds and activities of Prunus yedoensis Matsumura bark (PYMB) ethanol extracts (EE) and various other fractions. Among them, the highest total phenol content was 496.80 mg gallic acid equivalent/g in the ethyl acetate fractions (EAF). The flavonoid contents were 7.26-265.52 rutin equivalent mg/g, with the EAF showing the highest levels. The highest proanthocyanidin content was determined to be 326.31 catechin equivalent mg/g in the EAF and the remaining values in descending order were as follows: n-butanol, ethanol, dichloromethane, water, and n-hexane. EAF exhibited the highest DPPH, ABTS+, superoxide- radical scavenging activities, and reducing power, whereas the nitrite scavenging activities were the highest in the case of the EE. The n-hexane and water fraction antioxidant compounds and activities were lower than those of the other fractions. In summary, these results suggest that the PYMB EAF is a potential source of natural antioxidants.
