摘要(Abstract):

目的:研究荭草Polygonum orientale有效部位的化学成分。方法:应用色谱技术分离纯化,根据化合物的理化性质和波谱数据鉴定其结构。结果:分离并鉴定了7个化合物,分别为商陆素-3-O-β-D-半乳糖苷(ombuine-3-O-β-D-galactopyrano-side,1),商陆素-3-O-芸香糖苷(ombuine-3-O-rutinoside,2),色氨酸(tryptophan,3),槲皮素-3-甲醚(quercetin-3-O-methyl ether,4),山柰酚-3-O-(2″-O-α-L-鼠李糖基)-β-D-葡萄糖醛酸苷[kaempferol-3-O-(2″-O-α-L-rhamnopyranosyl)-β-D-glucuronopyranoside,5],槲皮素-3-O-(2″-O-α-L-鼠李糖基)-β-D-葡萄糖醛酸苷[quercetin-3-O-(2″-O-α-L-rhamnopyranosyl)-β-D-glucuronopyranoside,6],槲皮素-3-O-β-D-葡萄糖醛酸苷(quercetin-3-O-β-D-glucuronide,7)。结论:化合物4~7为首次从该种植物中分离得到,化合物1~3为首次从该属植物中分离得到,并首次归属化合物1的1H和13C-NMR谱信号。
Objective:To study the chemical constituents of the essential substance from the Polygonum oriental.Method:Chromatographic techniques were employed for isolation and purification of the constituents and their structures were determined by spectral analysis and chemical evidence.Result:Seven compounds were obtained and identified as ombuine-3-O-β-D-galactopyranoside(1),ombuine-3-O-rutinoside(2),tryptophan(3),quercetin-3-O-methyl ether(4),kaempferol-3-O-(2″-O-α-L-rhamnopyranosyl)-β-D-glucuronopyranoside(5),quercetin-3-O-(2″-O-α-L-rhamnopyranosyl)-β-D-glucuronopyranoside(6),quercetin-3-O-β-D-glucuronide(7).Conclusion:Compounds 4-7 were isolated from P.oriental for the first time and compounds 1-3 were firstly obtained from the genus Polygonum.The total 1H and 13C-NMR date of compound 1 were assigned for first time.
