The therapeutic potential of in reducing free radical-induced oxidative stress and inflammation particularly in hepatic diseases was evaluated in this study. The polyphenol rich seed extract showed good in vitro antioxidant. seed extract contained total phenolic content of 100.99 mg GAE/g dry weight and there was a positive correlation ( > 0.9) between total phenolic content and the antioxidant activities of the seed extract. seed extract significantly ( < 0.05) reduced the elevated levels of serum liver enzymes (ALT, AST, and ALP) and relative liver weight in paracetamol-induced liver hepatotoxicity in mice. Moreover, the extract significantly ( < 0.05) enhanced the antioxidant enzymes and glutathione (GSH) contents in the liver tissues, which led to decrease of malondialdehyde (MDA) level. The histopathological examination showed the liver protective effect of seed extract against paracetamol-induced histoarchitectural alterations by maximum recovery in the histoarchitecture of the liver tissue. Furthermore, histopathological observations correspondingly supported the biochemical assay outcome, that is, the significant reduction in elevated levels of serum liver enzymes. In conclusion, seed extract enhanced the in vivo antioxidant status and showed antihepatotoxic activities, which is probably due to the presence of phenolic compounds.
本研究评估了[具体物质]在减轻自由基诱导的氧化应激和炎症方面的治疗潜力,尤其是在肝脏疾病中的作用。富含多酚的[具体种子]提取物在体外表现出良好的抗氧化性能。[具体种子]提取物的总酚含量为100.99毫克没食子酸当量/克干重,且总酚含量与种子提取物的抗氧化活性之间存在正相关(>0.9)。在对乙酰氨基酚诱导的小鼠肝脏肝毒性实验中,[具体种子]提取物显著(<0.05)降低了血清肝酶(谷丙转氨酶、谷草转氨酶和碱性磷酸酶)水平的升高以及相对肝脏重量。此外,该提取物显著(<0.05)提高了肝脏组织中的抗氧化酶和谷胱甘肽(GSH)含量,从而导致丙二醛(MDA)水平降低。组织病理学检查显示,[具体种子]提取物对乙酰氨基酚诱导的组织架构改变具有肝脏保护作用,肝脏组织的组织结构得到了最大程度的恢复。此外,组织病理学观察相应地支持了生化检测结果,即血清肝酶水平升高的显著降低。总之,[具体种子]提取物提高了体内抗氧化状态并显示出抗肝毒性活性,这可能归因于酚类化合物的存在。
