Abstract:
Three ent-trachylobane diterpenes have been isolated from the leaf exudates of Psiadia punctulata and characterised as 6α,17,19-ent-trachylobantriol; 2α,18,19-ent-trachylobantriol; and 2β,6α,18,19-ent-trachylobantetraol. The structures were determined on the basis of spectroscopic evidence.
