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