The current study aimed at exploring hepatoprotective potential of Parrotiopsis jacquemontiana leaves methanol extract (PJM) in rat. PJM constituted of significant amount of total phenolic and total flavonoid content. PJM and ethyl acetate fraction (PJE) exhibited strong antioxidant potential (DPPH, hydroxyl ion, nitric oxide, iron chelating, β-carotene, reducing power and phosphomolybdate assay) in comparison to other extracts. CCl toxicity displayed significant (p<0.05) increase in level of TBARS, HO, nitrite while a decrease in SOD, CAT, POD and GSH in liver samples of CCl treated group. Serum analysis indicated significant increase in levels of ALT, AST and ALP and globulin whereas a decrease in albumin and total protein was also reported. In addition, levels of pro-inflammatory and fibrogenic cytokines (TNF-α, IL-6, TGF.β1, and leptin) of liver serum were elevated whereas adiponectin (anti-inflammatory cytokine) level was decreased in treated rats. CCl induced DNA damage and histopathological architecture was also studied. However, co-administration with PJM in a dose-dependent manner reversed all the above pathological parameters caused by CCl toxicity. HPLC-DAD analysis confirmed the existence of rutin, gallic acid, myricetin and caffeic acid in PJM and PJE while catechin was additionally present in PJM. Based on rich-antioxidant profile and hepatoprotective outcome on various pathological parameters prompted by CCl, it can be assumed to be a promising candidate shrub for phytomedicine development against various liver ailments and oxidative-stress related disorders.
本研究旨在探索 Parrotiopsis jacquemontiana 叶甲醇提取物(PJM)在大鼠体内的保肝潜力。PJM 中含有大量的总酚和总黄酮含量。与其他提取物相比,PJM 和乙酸乙酯部分(PJE)表现出很强的抗氧化潜力(DPPH、羟基离子、一氧化氮、铁螯合、β-胡萝卜素、还原力和磷钼酸盐测定)。与对照组相比,CCl 毒性导致 TBARS、HO、亚硝酸盐水平显著(p<0.05)升高,而 SOD、CAT、POD 和 GSH 水平降低。血清分析表明,CCl 处理组大鼠血清 ALT、AST 和 ALP 水平升高,球蛋白升高,白蛋白和总蛋白水平降低。此外,肝血清中促炎和纤维化细胞因子(TNF-α、IL-6、TGF.β1 和瘦素)水平升高,而抗炎细胞因子脂联素水平降低。CCl 诱导的 DNA 损伤和组织病理学结构也进行了研究。然而,以剂量依赖的方式与 PJM 共同给药可逆转 CCl 毒性引起的所有上述病理参数。HPLC-DAD 分析证实 PJM 和 PJE 中存在芦丁、没食子酸、杨梅素和咖啡酸,而儿茶素则额外存在于 PJM 中。基于丰富的抗氧化特性和对 CCl 引起的各种病理参数的保肝作用,可以假设它是一种有前途的植物药候选植物,可用于治疗各种肝脏疾病和与氧化应激相关的疾病。
