Phytochemical analysis of the leaves of Aglaia gigantea, Aglaia dasyclada and Aglaia oligophylla collected in Vietnam yielded three terpenoids, which included two triterpene Foveolin B (1), Niloticin (2) and one tetraterpene Lutein (3). The structures of these compounds were elucidated through extensive 1D and 2D NMR spectroscopy and analysis of their mass spectrometric data.
