Abstract
The leaves of the endemic Philippine plant, Dillenia philippinensis yielded 11 compounds including one new sulfated glucoside and a new seco-A-ring oleanane-type triterpenoid. The molecular structures of these compounds were elucidated by means of NMR, MS and other spectroscopic techniques, as well as by comparison with literature data. Anti-Leishmania activity and cytotoxic activity against A549 human lung adenocarcinoma cells were also examined.
