目的:研究土庄绣线菊乙醇提取物石油醚和氯仿分离部位的化学成分。方法:采用硅胶柱色谱和制备液相色谱等手段进行化学成分分离,运用理化性质和波谱数据(MS,1H-NMR,13C-NMR和HMBC等)鉴定化合物结构。结果:从土庄绣线菊乙醇提取物石油醚和氯仿分离部位分离得到6个五环三萜类化合物,分别鉴定为羽扇豆酮(1),木栓酮(2),羽扇豆醇(3),β-香树脂醇(4),白桦脂醇(5)和熊果醇(6)。结论:化合物1～5为首次从该属植物中分离得到,化合物6为首次从该植物中分离得到。
OBJECTIVE: To study the chemical constituents from the separation of petroleum ether and chloroform from ethanol extract of Spiraea polyclata. Methods: The constituents were separated by silica gel column chromatography and preparative liquid chromatography. The structures of compounds were identified by physicochemical properties and spectral data (MS, 1H-NMR, 13C-NMR and HMBC). Results: Six pentacyclic triterpene compounds were isolated from the petroleum ether and chloroform fractions of the ethanol extract of Spiraea polyclinia and identified as Lupinone (1), Woodpulpin (2), Lupine (3) , β-amyl alcohol (4), betulin (5) and arbutin (6). Conclusion: Compounds 1 ~ 5 were isolated from this genus for the first time. Compound 6 was isolated from this plant for the first time.
