From the stem of Ochna integerrima collected in Ben Tre province, three compounds have been isolated
and identified as (-)-syringaresinol (1), acid 16, 17-dihydroxy-ent-kauran-19-oic (2) and daucosterol (3).
The chemical structures of these compounds were determined by using on modern spectral analysis (1D
NMR, 2D-NMR and HR ESI-MS) and comparison with reliable published data. Among them, compounds
(1) and (2) were isolated from this species for the first time.
