Protective effect of Alchornea cordifilia leaf extract on carbon tetrachloride-induced liver damage in Wistar rats

The effect of aqueous extract of the leaves of Alchornea cordifolia on Carbon tetrachloride (CCl4)-induced liver damage was investigated in experimental rats. Treatment of separate groups of rats with 100mg/kg, 150mg/kg and 200mg/kg aqueous leaf extracts of Alchornea cordifolia for 2 weeks after establishment of CCl4 induced liver damage, resulted in significantly (P<0.05) less hepatotoxicity when compared to the CCl4-induced group, as measured by serum alkaline phosphatase (ALP), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities. The effect of extract was statistically significant (P<0.05) and was dose dependent. Histopathological study also showed significant reduction and even reversal of liver damage in the rats. The results of this study show that aqueous leaf extract of Alchornea cordifolia has a potent anti-hepatotoxic action against CCl4 induced liver damage in rats.
