星宿菜的黄酮类化学成分

Flavonoid Metabolites from Lysimachia fortunei Maxim.

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。

Abstract:

In order to understand the chemical constituents of Lysimachia fortunei Maxim., five flavonoids 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 identified 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 first time.
