Abstract

Hepatoprotective agents could prevent tissue damage and reduce morbidity and mortality rates; such agents may include folkloric or alternative treatments. The present study evaluated the protective effects of the flavonoid-rich fraction from rhizomes of Smilax glabra Roxb. (SGF) on carbon tetrachloride (CCl₄)-induced hepatotoxicity in rats. Sprague-Dawley male rats were orally treated with SGF daily and received CCl₄ intraperitoneally twice a week for 4 weeks. Our results showed that SGF at doses of 100, 300 and 500 mg/kg significantly reduced the elevated activities of serum aminotransferases (ALT and AST), alkaline phosphatase and lactate dehydrogenase and the level of hepatic thiobarbituric acid-reactive substances compared to the CCl₄-treated group. Moreover, SGF treatment was also found to significantly increase the activities of superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase, glutathione-S-transferase and glutathione compared with CCl₄-induced intoxicated liver. Histopathologic examination revealed that CCl₄-induced hepatic damage was markedly reversed by SGF. The results suggest that SGF has hepatoprotective and antioxidant properties in CCl₄-induced liver injury in rats.
