Carbon tetrachloride (CCl4) is a known environmental biohazard, which induces lipid peroxidation (LPO) and oxidative damage in rat liver. In this study, the hepatoprotective effect of Gossypitrin, a flavonoid extracted from Hibiscus elatus S.W, was investigated against the CCl4-induced in vivo hepatotoxicity. The levels of malondialdehyde (MDA) were assayed as an index of LPO and the levels of catalase (CAT) activity as a biomarker of oxidative damage. Leakage of aspartate aminotransferase (ALT) and lactate dehydrogenase (LDH), liver weight/body weight ratio as well as morphological parameters were used as signs of hepatotoxicity. CCl4 (1 ml/kg), intraperitoneally injected into rats, caused increased MDA production and CAT activity, and also a significant ALT and LDH leakage as compared to levels of these constituents in the control group. Changes in morphology, including steatosis, cells forming balloon cells and necrosis were evaluated in the hepatotoxin-induced damage. Treatment of rats with Gossypitrin (3.98, 5.97 and 8.95 mg/kg) 2 h before and 2 h after CCl4 injection, protected hepatocytes against cell injury induced by CCl4 and its efficacy as an antioxidant was similar to vitamin E (used as a reference antioxidant). These results are consistent with the conclusion that the toxicity of CCl4 is due to LPO and the generation of reactive oxygen species (ROS), and that Gossypitrin's protective effects relate to its direct radical scavenging ability and other antioxidative processes induced by its structure.
