甘肃醉鱼草化学成分研究(Ⅱ)

Study on the Terpenoids of Chemical Constituents of Buddleja purdomii (Ⅱ)

目的:研究甘肃醉鱼草地上部分的化学成分。方法:利用硅胶色谱柱层析、聚酰胺色谱柱层析,通过波谱分析鉴定其化学结构。结果:分离并鉴定了7个化合物为:木犀草素(luteolin,Ⅰ),木犀草素-7-O-β-D-葡萄糖苷(luteolin-7-O-β-D-glucoside,Ⅱ),反式咖啡酸(trans-caffeic acid,Ⅲ),顺式咖啡酸(cis-caffeic acid,Ⅳ),β-谷甾醇(β-stiosterol,Ⅴ),豆甾醇(stigmasterol,Ⅵ),二十九烷(nonacosane,Ⅶ)。

Objective ： To study the chemical constituents of Buddleja purdomii W. W. Smith. Methods ： The constituents were isolated and purified by various chromatographic methods and structurally identified by spectral analysis. Results： 7 compounds were obtained as luteolin（Ⅰ） ,luteolin-7-O-β-D-glueoside, （ Ⅱ ） ,trans-eaffeie acid（Ⅲ） , eis-eaffeie acid（Ⅳ） ,13-stiosterol（Ⅴ） ,stigmasterol （Ⅵ）, nonaeosane（ Ⅶ）. Conclusion： All these compounds are obtained from this plant for the first time.
