4个新2,2-二甲基色烯类化合物的分离和鉴定

THE ISOLATION AND IDENTIFICATION OF FOUR NEW 2,2-DIMETHYLCHROMENES

摘要: 从三叉苦(Evodia lepta Spr.Mer.)地上部分分离得到5个色烯类化合物,通过光谱解析和化学沟通的方法确定了它们的结构,其中4个为新化合物,依次命名为leptol B(I),ethyleptol B(I),methyleptol B(II)和leptene B(IV),另外1个为已知化合物 methylevodionol(V)。

Abstract: Four new 2,2-dimethylchromenes named leptol B (I), ethylleptol B (II), methylleptol B (III), leptene B (IV), along with a known chromene-methylevodionol (V) have been isolated from the aerial parts of Evodia lepta. Their structures were elucidated by spectroscopic analysis and chemical techniques.
