Abstract

(Ehrenb.) Bunge (Tamaricaceae), an indigenous plant to the Middle East region, is well-known as a medicinal plant for treating many human ailments. The current study aimed at exploring the polyphenol profile of the alcohol soluble fraction of aqueous extract, assessing its in vivo antifibrotic activity and the possible underlying mechanism, to unravel the impact of quantitative difference of sulphated polyphenols content on the antifibrotic activity of grown in two different habitats. Polyphenol profiling of extracts was performed using HPLC-HRESI-QTOF-MS-MS. The major polyphenol components included sulphated flavonoids, phenolic acids and free aglycones. The antifibrotic activity was evaluated through carbon tetrachloride-induced liver fibrosis in rats. Biochemical evaluations revealed that both fractions ameliorated the increased levels of hepatic aminotransferases, lipid peroxidation, hydroxyproline, α-smooth muscle actin (-SMA), tumor necrosis factor- (TNF-), cyclooxygenase-2 (COX-2) and nuclear factor kappa B (NF-κB). Moreover, both fractions reduced catalase activity (CAT) and enhanced hepatic glutathione (GSH) content. Histopathological imaging undoubtedly confirmed such results. In conclusion, the polyphenol-rich fraction exhibited potential antifibrotic activity in rats. Significant alterations in GSH levels were recorded based on the sulphated polyphenol metabolite content.

摘要

( Ehrenb. )Bunge (柽柳科),一种原产于中东地区的植物,作为治疗许多人类疾病的药用植物而广为人知。本研究旨在探索水提醇沉醇溶性部位的多酚谱,评估其体内抗纤维化活性及可能的作用机制,以揭示生长在两种不同生境下的植物中硫酸化多酚含量的定量差异对其抗纤维化活性的影响。采用 HPLC-HRESI-QTOF-MS-MS 对提取物中的多酚成分进行分析。主要的多酚成分包括硫酸化类黄酮、酚酸和游离苷元。通过四氯化碳诱导的大鼠肝纤维化来评估抗纤维化活性。生化评估结果显示,两种提取物均能改善肝转氨酶、脂质过氧化、羟脯氨酸、α-平滑肌肌动蛋白 (-SMA)、肿瘤坏死因子- (TNF-)、环氧化酶-2 (COX-2) 和核因子 kappa B (NF-κB)水平的升高。此外,两种提取物均能降低过氧化氢酶 (CAT) 活性,增加肝谷胱甘肽 (GSH) 含量。组织病理学图像无疑证实了这些结果。综上所述,富含多酚的部位在大鼠中表现出潜在的抗纤维化活性。根据硫酸化多酚代谢物含量,GSH 水平有显著变化。
