摘要: 从藏药乌奴龙胆(Gentiana urnula Smith)(龙胆科)的全草中分离到5个新的环烯醚萜甙,命名为乌奴龙胆甙(gentiournoside)A—E;它们的结构主要通过光谱分析得以确定。其中,乌奴龙胆A-C是二聚环烯醚萜甙,而乌奴龙胆甙D和E为马钱素型的环烯醚萜甙,所有这些化合物的分子中都具有一个2,3-二羟基苯甲酰基或其衍生物的取代基。

Abstract: Five new iridoidal glycosides, gentioumosides A-E were isolated from the whole herb of Gentiana urnula. Their structures were elucidated mainly by spectral methods. Among which gentioumosides A-C are bis-iridoidal glycosides while gentioumosides D and E are loganin type ones. It is noted that all the glycosides possess a 2,3-dihydroxy benxoyl unit or its derivative in the molecule.

Key words: Gentiana urnula
