摘　　要：Objective:To evaluate the ethanol extract of Voacanga grandifolia for hepatoprotective and antioxidant potential against ethanol-induced liver toxicity in rats.Methods:Sprague-Dawley rats were administered ethanol(7 g/kg)and then treated with 100 and 200 mg/kg of Voacanga grandifolia extract.The phytochemical constituents and antioxidant potential of Voacanga grandifolia extract were evaluated by GC-MS and in vitro antioxidant assays.Biochemical indicators for liver damage and pro-apoptotic and antiapoptotic gene expression were determined using biochemical kits,ELISA,and qRT-PCR,respectively.Additionally,histopathological study of the liver was performed.Results:GC-MS identified propanoic acid,meso-erythritol,D-pinitol,myo-inositol,and hexadecanoic acid in Voacanga grandifolia extract.Voacanga grandifolia extract(100 and 200 mg/kg)increased the concentration of enzymatic antioxidants while diminishing the levels of inflammatory cytokines and biochemical indicators.qRT-PCR assay showed that Voacanga grandifolia extracts upregulated antiapoptotic gene expression while downregulating pro-apoptotic gene expression.Furthermore,the plant extract improved the hepatic architecture of ethanol-intoxicated rats.Conclusions:Voacanga grandifolia extract demonstrates hepatoprotective activity against alcohol-induced liver injury in rats and could be a potential hepatoprotective agent.
