摘要Four undescribed ursane triterpenoids, sysamarins A-D, along with an undescribed oleanane triterpenoid, sysamarin E, were isolated from the ethyl acetate extract of the leaves of Syzygium samarangense. Their structures were elucidated on the basis of extensive spectroscopic analysis including HR-ESI-MS, 1D- and 2D-NMR techniques, and comparison with the data reported in the literatures. This is the first example of ursane and oleanane triterpenoids with an aliphatic ester of long chain at C-23 isolated from the genus Syzygium.
