摘要: 采用乙酰化方法对金雀花中正丁醇沉淀部分的化学成分进行研究。 金雀花的地上部分用75%的乙醇提取,乙醇总浸膏用去离子水饱和悬浮,依次用石油醚、乙酸乙酯、正丁醇萃取;其中正丁醇萃取物沉淀部分乙酰化衍生后采用各种柱色谱进行分离纯化,结合理化性质及光谱数据鉴定化合物结构。从正丁醇沉淀部分分离出4个化合物,分别鉴定为β-谷甾醇、1-三十烷醇、美迪紫檀素及车轴草醇,所有的化合物均为首次从该植物中分离得到。此外,乙酰化反应使得正丁醇沉淀部分的溶解性增加,极性降低,为其他植物中大极性化合物的分离纯化提供参考。

Abstract: The chemical constituents of n-butanol-insoluble portion of Parochetus communis Buch extract were studied by acetylation.The aerial part of P.communis was extracted by 75% ethanol and the ethanol extract was suspended in distilled water and successively extracted by petroleum ether,ethyl acetate,and n-butanol.The insoluble portion of n-butanol extract was partly acetylated,then various column chromatographic methods were used for the isolation and purification.The chemical structures of compounds were elucidated on the basis of physicochemical properties and spectral date.Six compounds were isolated from n-butanol-insoluble portion of P.communis Buch and identified as β-sitosterol,1-triacontanol,medicarpin and pratol.All compounds were isolated from the medical plant for the first time.In addition,the solubility of n-butanol-insoluble portion was increased and the polarity of the chemical composition was decreased by acetylation.This method provides a new reference for the separation of high-polar compounds in other plant.

Key words: Parochetus communis Buch., acetylation, n-butanol-insoluble portion, chemical constituents
