In vitro and in vivo hepatoprotective activity of Cissampelos pareira against carbon-tetrachloride induced hepatic damage.

ABSTRACT

Administration of hydroalcoholic extract of Cissampelos pareira roots (CPRE) and standard drug silymarin in rats showed significant hepatoprotective action against CCl4 induced hepatotoxicity. Elevated serum marker enzymes of AST, ALT, ALP and serum bilirubin were significantly reduced to near normal level in CPRE treated rats. Lipid peroxidation level was decreased significantly in CPRE 100, 200, 400 mg/kg doses treatment groups. In case of antioxidant enzymes SOD, catalase levels were increased significantly after CPRE 200, 400 mg/kg doses, similarly it increased the enzyme levels of GST, GPx, and GSH. CPRE 200, 400 mg/kg decreased cholesterol level, and increased triglyceride level. In vitro hepatoprotective activity of the extract was evaluated at 20, 40, 60, 80 and 100 µg/ml concentration against CCl4 (1%) induced toxicity in freshly isolated rat hepatocytes. HepG2 cells showed significant dose dependent increase in percentage viability at the doses 20, 40, 60, 80 and 100 µg/ml of CPRE compared to CCl4 exposed HepG2 cells. Results of this study strongly demonstrate Cissampelos pariera having good hepatoprotective potential.
