长白瑞香的化学成分(英文)

Chemical Constituents from Daphne koreana Nakai

目的:研究产自长白山地区的长白瑞香(Daphne koreana)的化学成分。方法:应用硅胶柱色谱,Sephadex LH-20和RP-18反相柱色谱的方法分离和纯化化合物,通过光谱方法及理化性质鉴定化合物结构。结果:从长白瑞香氯仿部位分离得到10个化合物,分别为:双白瑞香苷(1),7-甲氧基-木犀草素-5-O-β-D-葡萄糖苷(2),樱花苷(3),芫花苷(4),瑞香新素(5),异瑞香新素(6),5-去甲氧基瑞香新素(7),紫丁香苷(8),左旋松脂酚(9),左旋松脂酚-4-O-β-D-葡萄糖苷(10)。结论:所有化合物均为首次从该植物中分得。

AIM： To study the chemical constituents of the stems and barks of Daphne koreana from the hangbai Mountain in the North of China. METHODS： Compounds were separated by column chromatography with silica gel, Sephadex LH-20 and RP-18 silica gel. Their structures were elucidated on the basis of physiochemical and spectral analyses. RESULTS： Ten compounds were isolated from D. koreana and the structures were identified as daphnoretin-7-O-β-D-glucopyranoside （1）, luteolin-7-methylether-5-O-β-D-glucopyranoside （2）, sakuranin （3）, yuankanin （4）, daphneticin （5）, isodaphneticin （6）, 5′-demethoxydaphneticin （7）, syringin （8）, （-）-pinoresinol （9） and （-）-pinoresinol- 4-O-β-D-glucopyranoside （10）. CONCLUSION＇： Compounds 1 - 10 were isolated from this plant for the first time.
