Linn. is commonly used as a traditional medicine in India and China. The antioxidant potential of an ethanolic extract of (EEAB; 250 mg/kg and 500 mg/kg) was evaluated against CCL-induced toxicity in rats. Antioxidant activity was assessed by measuring the enzymatic and non-enzymatic antioxidants. Phytochemical constituents of EEAB were also analyzed by using UHPLC-QTOF-MS. EEAB treatment markedly reduced CCl effects on lipid peroxidation, cholesterol, triacylglycerides, and protein carbonyls. It increased the levels of phospholipids, total sulfhydryl, and antioxidant enzymes, which were reduced by CCl intoxication. Treatment with EEAB significantly alleviated the CCl effect on non-enzymatic antioxidants. Isoenzyme pattern analyses revealed that significant alterations in superoxide dismutase (SOD1), glutathione peroxidase (GPx2, GPx3), and catalase (CAT) occurred in rats that were exposed to CCl and restored post EEAB treatment. Moreover, CCl-induced down regulation of SOD, CAT, and GPx gene expression was conversely counteracted by EEAB. Its bioactivity may be due to its incorporation of major compounds, such as chlorogenic acid, quercetin, protocatechuic acid, lamioside, crocetin, and khayasin C. These results suggest that EEAB may be used as a potent antioxidant and hepatoprotective agent since it is a rich source of flavonoids and phenolic compounds.
Linn. 是印度和中国常用的传统药物。本研究评估了 Linn. 的乙醇提取物(EEAB;250mg/kg 和 500mg/kg)对 CCL 诱导的大鼠毒性的抗氧化潜力。通过测量酶和非酶抗氧化剂来评估抗氧化活性。还使用 UHPLC-QTOF-MS 分析了 EEAB 的植物化学成分。EEAB 治疗可显著降低 CCl 对脂质过氧化、胆固醇、三酰甘油和蛋白质羰基的影响。它增加了磷脂、总巯基和抗氧化酶的水平,这些水平因 CCl 中毒而降低。EEAB 治疗可显著减轻 CCl 对非酶抗氧化剂的影响。同工酶模式分析表明,暴露于 CCl 中的大鼠的超氧化物歧化酶(SOD1)、谷胱甘肽过氧化物酶(GPx2、GPx3)和过氧化氢酶(CAT)的同工酶谱发生了显著改变,并在 EEAB 治疗后得到恢复。此外,EEAB 逆转了 CCl 诱导的 SOD、CAT 和 GPx 基因表达下调。其生物活性可能与其含有主要化合物有关,如绿原酸、槲皮素、原儿茶酸、辣木苷、西红花酸和卡哈辛 C。这些结果表明,EEAB 可能作为一种有效的抗氧化和保肝剂使用,因为它是类黄酮和酚类化合物的丰富来源。
