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: quercetin-3'-O-beta-D-galactoside (1), 8-methoxyquercetin (2), pigenin (3), luteolin (4), quercetin (5), 3,5,7-trihydroxychromone (6), p-hydroxybenzaldehyde (7), beta-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.
目的
研究愉悦蓼全草的化学成分。
方法
采用硅胶柱色谱和葡聚糖凝胶LH - 20柱色谱对85%乙醇提取物进行分离。根据理化性质和波谱数据对从该植物中分离得到的化合物进行结构鉴定。
结果
从愉悦蓼全草中分离得到8个化合物，分别鉴定为：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）、β-谷甾醇（8）。
结论
所有化合物均为首次从该植物中分离得到，化合物5 - 8为首次从蓼属植物中分离得到。
