Phytochemical analysis of the extract of the leaves and twigs of Glochidion assamicum led to the isolation of four new oleanane-type triterpenoids, 21β-(benzoyloxy)olean-12-ene-3β,16β,23,28-tetraol (1), 21β-(benzoyloxy)olean-12-ene-3β,16β,28-triol (2), 21β-{(E)-cinnamoyloxy]olean-12-ene-3β,16β,23, 28-tetraol (3), and 21β-[(Z)-cinnamoyloxy]olean-12-ene-3β,16β,23,28-tetraol (4). Their structures were elucidated on the basis of spectroscopic evidence and mass-spectral data.
