Abstract : Background: Citrus macroptera has been used as a culinary fruit and medicinal plant in traditional medicine system in Bangladesh. The aim of the present study was to evaluate the presence of phenolic compounds in Citrus macroptera peel powder and the protective effect of Citrus macroptera against carbon tetrachloride (CCl4)- induced liver injury in rats. Methods: The hepatoprotective activity was assessed using various biochemical parameters such as liver marker enzymes (alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP)) and oxidative stress parameters. Histopathological changes in the liver of different groups were also studied. Results: Administration of CCl4 increased the serum ALT, AST, ALP enzymatic activities and lipid peroxidation products but decreased the cellular antioxidant activities and reduced glutathione (GSH) levels in rats which were brought back to near normal levels by the treatment with Citrus macroptera. Citrus macroptera administration has also shown to decrease the necrotic zones, fibrosis and inflammatory cell infiltration in CCl4 treated rats. HPLC-DAD analysis of Citrus macroptera extract showed the great presence of caffeic acid and (?) epicatechin. Conclusion: The results of this study suggest that Citrus macroptera exerts hepatoprotective activity via promoting the antioxidant defense against CCl4-induced oxidative liver damage.
