To investigate the antioxidative effects of Prunus mume ethanol extract on the ethanol-induced hepatotoxicity in rat liver, Sprague-Dawley rats weighing 120∼160 g were divided into 5 groups; normal group(NOR), Prunus mume ethanol extract 200mg/kg treated group(PME), ethanol(10 mL/kg, 35%) treated group(ETH), Prunus mume ethanol extract 200 mg/kg and ethanol treated group (PML) and Prunus mume ethanol extract 400 mg/kg, and ethanol treated group(PMF), respectively. The antioxidative activity in vitro was reduced in order of EtOAC>n-hexane>water> chloroform fraction. The growth rate and feed efficiency ratio decreased by ethanol administration were gradually increased to the adjacent level of NOR by administering Prunus mume ethanol extract. It was observed that activities of catalase, superoxide dismutase(SOD), xanthine oxidase and glutathione peroxidase(GSH-Px) of liver and alanine aminotransferase(ALT) and asparate aminotransferase(AST) of serum were elevated by ethanol administration. Besides, Prunus mume ethanol extract markedly decreased elevated activites of catalase, GSH-Px, ALT and AST, except in activites of SOD and xanthine oxidase compared to ETH. Also, the depleted content of GSH by ethanol was increased similar to NOR level by administering Prunus mume ethanol extract. These results suggested that Prunus mume ethanol extract has a possible protective effect on the ethanol-induced hepatotoxicity in rat liver.
