摘 要:目的:研究蓼科蓼属植物愉悦蓼Polygonum jucundum全草的化学成分,为研究蓼属化学分类学提供物质基础。方法:以85%乙醇热回流提取,采用硅胶、凝胶柱色谱等多种色谱技术以及重结晶等方法分离纯化化合物,根据理化性质和波谱数据进行结构鉴定。结果:共分离鉴定了8个化合物,分别为槲皮素-3'-O-β-D-半乳糖苷(1),8-甲氧基槲皮素(2),芹菜素(3),木犀草素(4),槲皮素(5),3,5,7.三羟基色原酮(6),对羟基苯甲醛(7)和β-谷甾醇(8)。结论:以上化合物均为首次从该种植物中分得,其中化合物1,2,6—8为首次从蓼属植物中发现。Objective: To investigate the chemical constituents in herbs of Polygonum jucundum. Method: The 85% ethanol extract was separated by means of silica gel and Sephadex LH-20 column chromatography. The compounds isolated from the plant were identified by physicochemical properties and spectroscopic evidence. Result: Eight compounds were isolated and identified as: quereetin-3'-O-β-D-galactoside ( 1 ), 8 -methoxyquercetin ( 2), pigenin (3), luteolin (4), quercetin (5), 3,5,7-trihydroxychromone ( 6), p-hydroxybenzaldehyde (7), β-sitosterol (8). Conclusion: All compounds were isolated from this plant for the first time, compounds 5- 8 were isolated from the genus Polygonum for the first time.
