摘 要:目的对翠云草化学成分进行研究。方法采用大孔吸附树脂、聚酰胺柱、正相硅胶柱、Sephadex LH-20柱色谱以及制备高效液相色谱等方法进行分离纯化,根据化合物的理化性质和光谱方法鉴定结构。结果从翠云草75%乙醇提取物中分离得到10个化合物,分别鉴定为:3,5-二甲基儿茶酚(1)、十七烷酸-2,3-二羟基丙酯(2)、没食子酸辛酯(3)、对羟基苯甲醛(4)、对羟基苯乙酮(5)、大黄素(6)、大黄酚(7)、大黄素-6-甲醚(8),β-谷甾醇(9),β-胡萝卜苷(10)。结论化合物1~4为首次从卷柏属中分离得到,化合物6~8、10为首次从翠云草中分离得到。Objective To determine the chemical constituents of Selaginella uncinata(Desv.) Spring. Methods The compounds were isolated and purified from the 75% ethanol extract of S. uncinata by multiple chromatographic techniques including macroporous resin, polyamide, silica gel, Sephadex LH-20 and preHPLC. The structures were identified on the basis of thierphysico-chemical properties and spectroscopic data analyses. Results Ten compounds were isolated and determined as 3, 5-dimethylcatechol(1), heptadecanoic acid-2, 3-dihydroxypropyl ester(2), octyl gallate(3), p-hydroxybenzaldehyde(4), p-hydroxyacetophenone(5), emodin(6), chrysophanol(7), physcion(8), β-sitosterol(9), β-daucosterin(10). Conclusion Compounds 1-4 have been firstly isolated from the genus of Selaginella and compounds 6- 8 and 10 have been isolated from the species for the first time.
