has been commonly used as a multi-use medicinal plant in folk medicine worldwide. The objectives of our study were to determine the different metabolites in the Rottb. methanol extract, and to assess its in vivo gastroprotective effect in ethanol-induced gastric ulcer model in rats. Serum levels of galactin-3 and TNF- were employed as biochemical markers. To pinpoint for active agents, comprehensive metabolites profiling of extract via UPLC-qTOF-MS/MS was employed. A total of 77 chromatographic peaks were detected, of which 70 were annotated. The detected metabolites were categorized into phenolic acids and their derivatives, flavonoids, stilbenes, aurones, quinones, terpenes, and steroids. Rats were divided into six groups; healthy control, ulcer control, standard drug group, and 25, 50, 100 mg/kg of treated rats. Pre-treatment with alcohol extract significantly reduced galactin-3, and TNF- in ethanol-induced ulcer model at 25, 50, and 100 mg/kg. Further histopathological and histochemical studies revealed moderate erosion of superficial epithelium, few infiltrated inflammatory cells, and depletion of gastric tissue glycoprotein in the ulcer group. Treatment with the extract protected the gastric epithelial cells in a dose-dependent manner. It could be concluded that extract provides significant gastroprotective activity in ethanol-induced gastric ulcer and ought to be included in nutraceuticals in the future for ulcer treatment.
在世界范围内,作为一种多用途药用植物,[草药名]已被广泛应用于民间医学。我们的研究目的是确定[草药名]甲醇提取物中的不同代谢物,并评估其在乙醇诱导的大鼠胃溃疡模型中的体内胃保护作用。血清半乳糖凝集素-3 和 TNF-水平被用作生化标志物。为了确定有效成分,我们采用 UPLC-qTOF-MS/MS 对提取物进行了全面的代谢产物分析。共检测到 77 个色谱峰,其中 70 个得到注释。检测到的代谢物分为酚酸及其衍生物、类黄酮、芪类、奥罗昔因、醌类、萜类和甾体。将大鼠分为六组:健康对照组、溃疡对照组、标准药物组和 25、50、100 mg/kg 的[草药名]处理组。[草药名]醇提物预处理可显著降低乙醇诱导溃疡模型中半乳糖凝集素-3 和 TNF-的水平,在 25、50 和 100 mg/kg 剂量下效果显著。进一步的组织病理学和组织化学研究显示,溃疡组的浅层上皮有中度侵蚀,浸润的炎性细胞较少,胃组织糖蛋白耗竭。提取物以剂量依赖的方式保护胃上皮细胞。可以得出结论,[草药名]提取物在乙醇诱导的胃溃疡中具有显著的胃保护作用,将来应该被包含在治疗溃疡的营养保健品中。
