Oleanane-Type Triterpenoids from Glochidion assamicum

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, 2...

Summary: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.
