Two known diterpenes, (ent)-2-oxokaur-16-en-18,19-diol (psiadin) and (ent)-kaur-16-en-2α,18,19-triol, and three novel diterpenes, (ent)-16β,17-dihydroxykauran-20-oic acid, 2-oxotrachyloban-18,19-diol and trachyloban-2β,6β,19-triol have been isolated from the leaf exudate of Psiadia punctulata. The structures of the diterpenes was established on the basis of spectroscopic analysis and previously published data on the known compounds.
