紫茎泽兰的化学成分初报
A BRIEF REPORT OF THE CHEMICAL CONSTITUENTS FROM EUPATORIUM ADENOPHORUM
【摘要】 <正> 紫茎泽兰(Eupalorium adenophorum Spreng)原产中美墨西哥,现在滇南一带广泛分布,对林、牧业生产造成严重危害。其化学成分研究未见报道。 从紫茎泽兰的叶和花序中,分到九个单体,经详细的光谱解析和与标准品对照,其中五个成分的化学结构分别为:正三十二烷n-dotriacontane(1),β-谷甾醇β-sitosterol(2),豆甾醇stigmasterol(3),蒲公英醇棕榈酸酯taraxasteryl palmitate(4),蒲公英醇乙酸酯taraxastcryl acetate(5)。
【Abstract】 We examined the chloroform extract of the leaves and inflorescence of Eupatorium adenophorum Sprtng collected in the suburb of Kunming, Yunnan, China. Nine colourless crystals were isolated. Five among them were identified to be dotriacontanc (1) ,β-sitosterol( 2 ), stigmasterol (3) , taraxasteryl palmitate ( 4 ) , taraxasteryl acetate ( 5 ) by spectroscopic evidences and comparison with standard samples.
