Two new oleanane triterpenoids, sysamarins F (1) and G (2), along with one known analogue (3), were isolated from the leaves of Syzygium samarangense. Their structures were elucidated by means of extensive spectroscopic techniques, including interpretation of 1D and 2D NMR spectra and comparison with the values reported in the literature.
