摘　　要：本文对毛脉酸模(Rumex gmelini Turcz.)石油醯和乙酸乙酯部位进行了系统的研究。将50%乙醇提取物石油醯和乙酸乙酯部位采用硅胶柱色谱、Sephadex LH-20凝胶柱色谱等进行分离纯化,通过理化性质和^1H-NMR,^13C-NMR等波谱学测试技术进行结构鉴定。从中分离纯化得到7个化合物,分别为酸模素⑴,β-谷苗醇(2),大黄酚(3),大黄素甲醚(4),大黄素(5),酸模素-8-O-β-D-葡萄糖苷(6),白藜芦醇(7)。其中,化合物2,6为首次从该植物中分离得到。In this paper,a systematic study of the petroleum ether and ethyl acetate parts of Rumex gmelini Turcz.was carried out.All compounds were extracted by 50%ethanol,petroleum ether and ethyl acetate,and then the extracts were isolated and purified?by silica gel column chromatography and Sephadex LH-20.The structures were identified on the basis of physicochemical properties and spectral data,and other spectroscopy testing techniques,such as^1H-NMR and ^13C-NMR.Thirteen compounds were isolated from Rumex gmelini Turcz.and elucidated as nepodin(1),β-sitosterol(2),chrysophanol(3),physcion(4),emodin(5),nepodin-8-O-β-D-glucoside(6),resveratrol(7).Among them,compounds 2,6 are isolated from this plant for the first time by this study.
