Hepatoprotective effects of momordin Ic and oleanolic acid obtained from Kochiae Fructus (KF), the fruit Of a traditional Oriental medicinal plant, were evaluated against carbon tetrachloride (CCl4)-induced liver damage in rats. Male Sprague-Dawley rats were divided into four groups: control, CCl4-treated, CCl4 Plus momordin Ic-treated (MMDIc-CCl4), and CCl4 plus oleanolic acid-treated (OAA-CCl4). Momordin Ic (30 mg/kg of body weight) and oleanolic acid (30 mg/kg of body weight) were orally administered once a day for 14 days. A Mixture of 0.2 mL/100 g of body weight Of CCl4 ill olive oil (1:1, vol/vol) was injected 30 minutes after the final administration of momordin Ic and oleanolic acid. The momordin le and oleanolic acid pretreatments resulted in significantly lower serum transaminase, lactic dehydrogenase, and gamma-glutamyl-transferase levels in the CCl4-treated rats. The CCl4-treated rats had significantly lower activities of glutathione, glutathione reductase, glutathione S-transferase, superoxide dismutase, catalase, and glutathione peroxidase. However, pretreatment with momordin Ic and oleanolic acid reduced the effect Of CCl4 and helped maintain levels of the enzymes. Pretreatment with momordin le and oleanolic acid resulted in significantly lower production of aminopyrine N-demethylase and aniline hydroxylase in the CCl4-treated rats. Pretreatment with momordin Ic resulted in lower catalase and aminopyrine N-demethylase activity induction by CCl4, towards normalization. Momordin Ic and oleanolic acid obtained from KF appeal, to contribute to alleviating the adverse effects Of CCl4 treatment by enhancing the hepatic antioxidant defense system.
