摘要:

采用柱色谱分离技术，在都匀楼梯草 （Elatostema duyunens）正丁醇和石油醚部位中分离得到18个化合物，通过MS和NMR数据分析，鉴定出10个化合物，分别为：槲皮素（1）、槲皮素-3-O-β-D-半乳糖苷（2）、槲皮素-3-O-β-D-葡萄糖苷（3）、山奈酚（4）、山奈酚-3-O-β-D-葡萄糖苷（5）、齐墩果酸（6）、β-谷甾醇（7）、熊果酸（8）、豆甾醇（9）和正二十五烷（10）。

Abstract:

Column chromatographic technique was used for the isolation and purification of the chemical constituents of the n-butanol portion and the petroleum ether portion from Elatostema duyunens.,18 compounds are separated, and 10 compounds were identified by MS and NMR data analysis, Quereetin(1), Quercetin-3-O-β-D-galactoside(2), Quercetin-3-O-β-D-glucoside(3), Kaempferol(4), Kaempferol 3-O-β-D-glucoside(5), Oleanic acid(6), β-sitosterol(7), Ursolic acid(8), stigmasterol(9), and n-pentacosane(10), respectively.
