OBJECTIVE: To investigate hepatoprotective activity of ethanol extract of Melothria heterophylla Lour Cogn. (EEMH) against CCl(4)-induced hepatic damage in rats.
METHODS: β-sitosterol was isolated by column chromatography and characterized spectroscopically. Two different doses (200 and 400 mg/kg bw) of EEMH were administered orally in alternate days. The hepatoprotective activity was studied in liver by measuring biochemical parameters such as serum aspartate amino transferase (AST), alanine amino transferase (ALT), alkaline phosphatase (ALP), total protein and total bilirubin. Lipid peroxidation product and different antioxidant enzyme activities were assessed in liver homogenate.
RESULTS: EEMH reduced all biochemical parameters and lipid peroxidation, as well as it increased the antioxidant enzyme activities in comparison with silymarin. The protective effect of the extract on CCl(4) induced damage was confirmed by histopathological examination of the liver.
CONCLUSIONS: This result strongly supports the protective effect of EEMH against acute liver injury, and may be attributed to its antioxidative activity.
