Abstract
Two known diterpenes, (ent)-2-oxokaur-16-en-18,19-diol (psiadin) and ( ent)-kaur-16-en-2 alpha,18,19-triol, and three novel diterpenes, (ent) -16 beta, 17-dihydroxykauran-2O-oic acid, 2-oxotracnyloban-18,19-diol and trachyloban-2 beta,6 beta, 19-triol have been isolated from the le af exudate of Psiadia punctulata. The structures of the diterpenes was established on the basis of spectroscopic analysis and previously pub lished data on the known compounds. (C) 1997 Elsevier Science Ltd.
