METHODS： In the in vitro study, a primary hepatocyte monolayer culture was treated with CCh and extract of Anogeissus latifolia. Hepatoprotective activity was demonstrated in the CCh damaged primary monolayer culture. In the in vivo study, the hepatoprotective activity of a hydroalcoholic extract ofAnogeissus latifolia was analyzed in liver injured CCh-treated rats. Biochemical parameters including serum transaminases [aspartate aminotransferase （AST） and alanine aminotransferase （ALT）] and alkaline phosphatase （ALP） in serum wereanalyzed. The biochemical findings were supplemented with histopathological examination of rat liver sections. RESULTS： In vitro： primary hepatocyte monolayer cultures were treated with CCh and extract of Anogeissus latifolia. A protective activity could be demonstrated in the CCh damaged primary monolayer cultUre. In vivo： Hydroalcoholic extract of Anogeissus latifolia （300 mg/kg） was found to have protective activity in rats with CCh-induced liver damage as judged from serum marker enzyme activity. CONCLUSION： The above findings lead to the conclusion that the hydroalcoholic extract of Anogeissus latifol/a is hepatoprotective. Hence, we suggest that the inclusion of this plant in the management of liver disorders is justified.展开更多
