The present study is to evaluate the hepatoprotective and antioxidant activity of methanolic extract of Amorphophallus commutatus var. wayanadensis against carbon tetrachloride induced hepatotoxicity in mice models. Hepatic injury was induced by injecting 0.2% CCl4 in olive oil intra peritoneally on 15th day of drug administration. Hepatoprotective activity was evaluated by estimating the levels of serum markers like alanine aminotransferase (ALT) and aspartate aminotransferase (AST), alkaline phosphatase (ALP), bilirubin and histopathological studies. Antioxidant potential of the extract was estimated by measuring the levels of antioxidant enzymes, superoxide dismutase (SOD), catalase (CAT), glutathione-s-transferase (GST), glutathione peroxidase (GPx) and total reduced glutathione in the liver samples. Histopathological and biochemical results elicited the methanolic extract of A. commutatus has significant hepatoprotective activity comparable to the standard silymarin. The extract also showed dose dependent increase of antioxidant enzymes in CCl4 induced hepatotoxicity models. The methanolic extract of A. commutatus showed significant hepatoprotective and antioxidant activity which might be attributed due to the polyphenolic compounds present in the extract.
本研究旨在评估魔芋(Amorphophallus commutatus var. wayanadensis)甲醇提取物对四氯化碳诱导的小鼠肝毒性的保肝和抗氧化活性。在给药第15天,通过腹腔注射0.2%四氯化碳橄榄油溶液诱导肝损伤。通过测定血清标志物如丙氨酸转氨酶(ALT)、天冬氨酸转氨酶(AST)、碱性磷酸酶(ALP)、胆红素水平以及组织病理学研究来评估保肝活性。通过测量肝脏样本中抗氧化酶超氧化物歧化酶(SOD)、过氧化氢酶(CAT)、谷胱甘肽 - S - 转移酶(GST)、谷胱甘肽过氧化物酶(GPx)水平以及总还原型谷胱甘肽来评估提取物的抗氧化潜力。组织病理学和生化结果表明,魔芋甲醇提取物具有与标准水飞蓟宾相当的显著保肝活性。在四氯化碳诱导的肝毒性模型中,该提取物还显示出抗氧化酶的剂量依赖性增加。魔芋甲醇提取物表现出显著的保肝和抗氧化活性,这可能归因于提取物中存在的多酚类化合物。
