摘要


利用硅胶柱色谱、Sephadex LH-20柱色谱等方法对酸模属植物戟叶酸模 (Rumexhastatus) 的非石油醚部位进行分离和纯化,根据化合物理化性质以及波谱数据分析鉴定其结构.共分离得到7个化合物,分别为1-O-阿魏酰基-β-D-吡喃葡糖苷(1)、蔗糖(2)、酸模素(3)、酸模素-8-O-β-D-葡萄糖苷 (4)、反式白藜芦醇 (5)、反式白藜芦醇-3-O-β-D-葡萄糖苷(6)、β-谷甾醇(7).化合物1、2首次从该植物中分离得到. Isolation and purification of non-petroleum ether extract of RumexhastatusD. Don were carried out on the column chromatography of silica gel and Sephadex LH-20. Their structures were elucidated on basis of physicochemical properties and spectral data. Seven compounds were isolated and identified as 1-O-feruloyl-β-D- glucopyranoside (1), α-D-glucopyranosido-β-D-fructofuranoside (2), nepodin (3), nepodin-8-O-β-D-glucopyranoside (4), resveratrol (5), resveratrol-3-O-β-D- glucopyranoside (6), β-sitosterol (7).Compounds 1 and 2 were isolated from the Rumex plantsfor the first time.Compounds 3 and 4 were naphthalenoidderivatives; Compounds 5 and 6 were stilbenoidderivatives.
