Hepatoprotective and Antioxidant Role of Ziziphus jujuba Leaves on Paracetamol Induced Hepatic Damage in Rats

摘要

To evaluate the hepatoprotective activity of aqueous extract of Ziziphus jujuba leaves against paracetamol-induced liver injury in experimental rats. Ziziphus jujuba has been traditionally used in the Ayurvedic system of medicine as a chief ingredient in many polyherbal formulations as antioxidant. To evaluate the antioxidant and hepatoprotective activity of aqueous leaf extract of Ziziphus jujuba leaves. Animals were pre-treated with the aqueous leaf extract for 7 days and then toxicity was induced with a single paracetamol oral injection. Pre-treatment with 150mg/kg of aqueous leaf extract of Ziziphus jujuba improved the reduced glutathione (oxidized), SOD, catalase, and peroxidase levels significantly as compared to control group. Silymarin was used as standard reference and exhibited significant hepatoprotective activity against paracetamol induced hepatotoxicity in rats. The biochemical observation was reported for rat liver sections. The results of this study strongly indicate that Ziziphus jujuba leaves have potent hepatoprotective action against paracetamol induced hepatic damage in rats. Aqueous extract was found more potent hepatoprotective. Meanwhile, in vivo antioxidant activities were also screened which were positive for aqueous extracts. On the basis of this study, we conclude that aqueous extract of Ziziphus jujuba possesses in vivo antioxidant activity and can be employed in protecting tissues from oxidative damage and stress.
