大高良姜中的一个新苯丙素类化合物

摘要

AIM:To study the chemical constituents from the rhizome ofAlpinia galanga METHODS:Silica gel and Sephadex LH-20 column chromatographies were used to isolate the chemical constituents,and spectroscopic techniques were employed to elucidate their structures.RESULTS:A new phenylpropanoid was isolated from the rhizome of Alpinia galanga.Its structure was established as 4,4'[(2E,2'E)-bis(prop-2-ene)-1,1'-oxy]-diphenyl-7,7'-diacetata.CONCLUSION:The compound is a new phenylpropanoid.%目的:研究大高良姜(Alpinia galanga)的化学成分.方法:运用硅胶柱色谱,Sephadex LH-20柱色谱号方法分离和纯化化合物,根据理化性质和光谱数据鉴定化合物的结构.结果:从大高良姜中分离并鉴定得到1个化合物,鉴定为对二乙酰基苯丙烯醚.结论:该化合物为新化合物.
