摘要
目的:研究鳄嘴花全草的化学成分。方法:采用硅胶柱层析、Sephadex LH-20柱、高效液相色谱、重结晶等方法进行分离纯化,根据理化性质和波谱数据鉴定化合物结构。结果:从鳄嘴花干燥全草的85%乙醇提取物中分离得到10个化合物,分别鉴定为:羽扇豆醇(1)、豆甾醇(2)、β-谷甾醇(3)、β-谷甾酮(4)、β-sitosterol palmitate(5)、(9E,11Z)-14-hydroxyotadecan-9,11-dienoic acid(6)、13-hydroxy-(9Z,11E,15E)-octadecatrienoic acid(7)、2,3-hydroxypropyl-(9Z,12Z)-octadecadienoate(8)、邻苯二甲酸二丁酯(9)、邻苯二甲酸二正戊酯(10)。结论:其中,化合物4~10为首次从该植物中分离得到,化合物4~8、10为首次从爵床科植物中分离得到。
Objective: To investigate the chemical constituents from Clinacanthus nutans herbs.Methods: The constituents from Clinacanthus nutans were isolated and purified by the chromatography on silica gel and Sephadex LH-20 columns as well as recrystallization.Their structures were identified on the basis of physiochemical properties and spectroscopic data analysis.Results: Ten compounds were isolated from the 85% ethanol extract of Clinacanthus nutans and identified as lupeol(1),stigmasterol(2),β-sitosterol(3),β-sitostenone(4),β-sitosterol palmitate(5),(9 E,11 Z)-14-hydroxyotadecan-9,11-dienoic acid(6),13-hydroxy-(9 Z,11 E,15 E)-octadecatrienoic acid(7),2,3-hydroxypropyl-(9 Z,12 Z)-octadecadienoate(8),dibutyl phthalate(9) and dipentyl phthalate(10).Conclusion:Compounds 4 ~ 10 are isolated from this plant for the first time,and compounds 4 ~ 8,10 are isolated from Acanthaceae family for the first time.
