Abstract The investigation of a further Flourensia species afforded in addition to already known compounds 12 new sesquiterpene acids isolated as their methyl esters, a new eudesmane diol, four lupane derivatives and two flavanones, two cinnamic acid derivatives, also isolated as methyl esters and a ketone. The structures are elucidated mainly by spectroscopic methods and by some chemical transformations
摘要 除已知化合物外,对另一种 Flourensia 物种的研究还提供了 12 种新的倍半萜酸作为其甲酯分离、一种新的丁香二醇、四种羽扇豆烷衍生物和两种黄烷酮、两种肉桂酸衍生物,也分离为甲酯和一种酮. 这些结构主要通过光谱方法和一些化学转化来阐明。分离出的几种化合物与从其他 Flourensia 物种中分离出的化合物或多或少相似;然而,大量的eudesmanes是不寻常的。该属的整体情况还是比较统一的。与 Helianthella 的密切关系是显而易见的,而与位于同一亚部落的 Helianthus 没有明显的关系。
