Three ent-trachylobane diterpenes have been isolated from the leaf exudates of Psiadia punctulata and characterised as 6alpha,17,19-ent-trachylobantriol; 2alpha,18,19-ent-trachylobantriol; and 2beta,6alpha,18,19-ent-trachylobantetraol. The structures were determined on the basis of spectroscopic evidence.
从刺冠菊(Psiadia punctulata)的叶渗出物中分离出三种对映-贝壳杉烷二萜,并鉴定为6α,17,19-对映-贝壳杉三醇;2α,18,19-对映-贝壳杉三醇;以及2β,6α,18,19-对映-贝壳杉四醇。这些结构是根据光谱证据确定的。
