Abstract
Chrysin is a natural, biologically active compound present in many plants and possesses potent anti-inflammatory, anticancer and antioxidation properties. This work was designed to investigate the effect of chrysin, on the hepatoprotective efficacy in D-galactosamine-intoxication rats. D-galactosamine-induced toxicity was manifested by the elevation of serum hepatic marker enzyme activities (aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase and gamma-glutamyl transpeptidase) and the lipid peroxidation process and by decreasing the antioxidant capacity of the plasma, erythrocyte and tissues. Treatment with chrysin (25, 50 and 100 mg/kg body weight) decreased hepatic marker enzyme activities and lipid peroxidation products such as thiobarbituric acid reactive substances, lipid hydroper-oxides and conjugated dienes, increased the activities of free-radical scavenging enzymes superoxide dismutase, catalase and glutathione peroxidase and the levels of non-enzymatic antioxidants reduced glutathione, vitamin C and vitamin E. These findings demonstrate that chrysin acts as a hepatoprotective and antioxidant agent against D-galactosamine-induced hepatotoxicity. (C) 2010 Elsevier B.V. All rights reserved.
