As well-being foods pursuing healthy life are becoming popular, interest in Rubus coreanus Miquel (RCM) fruit, a type of Korean blackberry, is increasing due to its medicinal actions including protecting the liver, brightening the eyes, and alleviating diabetes. This study was carried out to evaluate the hepatoprotective effects of RCM concentrates on liver injuries induced by carbon tetrachloride ($CCl_4$) in rats. RCM, produced in June ~ July 2008 at Chunbook, Gochang (South Korea), was finely mashed. The seeds were removed and the juices were condensed. Thirty-two Sprague-Dawley rats were divided into four groups according to treatment: normal (eight rats), $CCl_4$, 1% RCM, and 2% RCM. Experimental diets were provided to the experimental animals for 4 weeks. We measure total cholesterol, high density lipoprotein-cholesterol (HDL-C), aspartate amino transferase (AST), alanine amino transferase (ALT), and alkaline phosphatase (ALP) levels. Part of the livers was isolated for histopathological evaluation, and analyzed for lipid peroxide (TBARS), superoxide dismutase (SOD) and liver proteins. The activities of serum AST, ALT, and ALP were elevated following $CCl_4$ administration. Levels of hepatic TBARS were also significantly increased in the $CCl_4$ groups. However, hepatic TBARS levels and the activities of serum enzymes were markedly reduced by supplementation with the RCM concentrates (P < 0.05). Hepatic SOD activity increased in the RCM concentrates group versus $CCl_4$ groups. Histopathological examination revealed massive necrosis in the centrilobular area and degenerative changes caused by $CCl_4$ were ameliorated by dietary supplementation with RCM concentrates. These results suggest that RCM concentrates have hepatoprotective effects and may improve the symptoms of liver injuries.
