Abstract
A new euphane triterpenoid, (20R,23E)-eupha-8,23-diene-3 beta,25-diol, was isolated from the leaves of Tripetalum cymosum and its structure was determ ined by spectral analysis and chemical correlation with euphol. Caryophylle ne oxide, friedelin, euphol and putranjivic acid were also obtained from th e leaves whilst the bark afforded euphol, glutin-5-en-3 beta-ol, butyrosper mol and dammara-20,24-dien-3 beta-ol.
