【摘要】 为了解星宿菜(Lysimachia fortunei Maxim.)的化学成分,利用溶剂萃取和色谱分离手段,从星宿菜全草的乙醇提取物的乙酸乙酯萃取部位分离得到了5个黄酮类化合物。经波谱分析及与文献数据对照,分别鉴定为:槲皮素(1)、异鼠李素-3-O-(6-香豆酸酯)-β-D-葡萄糖苷(2)、山奈酚-3-O-β-D-半乳糖苷(3)、金丝桃苷(4)和山奈酚-3-O-[6-(3-羟基-3-甲基戊二酸单酯)]-β-D-葡萄糖苷(5),其中化合物2和5为首次从珍珠菜属植物中分离获得。更多还原

【Abstract】 In order to understand the chemical constituents of Lysimachia fortunei Maxim., fi ve fl avonoids were isolated from the ethyl acetate-soluble fraction of ethanol extract of whole herbs of L. fortunei. On the basis of spectral data, they were identifi ed as: quercetin(1), isorhamnetin-3-O-(6-coumaroyl)-β-D-glucopyranoside(2), kaempferol-3-O-β-D-galactopyranoside(3), hyperin(4) and kaempferol-3-O-[6-(3-hydroxy-3-methylglutaroyl)]-β-D-glucopyranoside(5). Among them, compounds 2 and 5 were obtained from the genus Lysimachia for the fi rst time.更多还原
