Abstract

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.
