Macvicaria species have been investigated and a new cyclopropane pseudoguaiane was isolated and its structure elucidated by chemical and spectral evidence. Macvicaria ulophylla and the Porella species, except P. caespitans ssp. setigera, contain the diterpene dialdehyde, perrottetianal A. (+)-Aristolone, (−)-α-eudesmol, and related sesquiterpene hydrocarbons and alcohols, enantiomeric to those found
摘要 研究了6 种Porella 种和1 种Macvicaria 种,分离了一种新的环丙烷假愈创木,并通过化学和光谱证据阐明了其结构。Macvicaria ulophylla 和 Porella 物种,除了 P. caespitans ssp。setigera,含有二萜二醛、perrottetianal A. (+)-Aristolone、(-)-α-eudesmol 和相关的倍半萜烃和醇,与高等植物中发现的那些对映异构体,已从 Porella 物种中分离出来。
