title: Chemical constituents from Pterocarpus soyauxii.
abstract: Three new benzofurans (1-3) and one new isoflavan (4), pteroyanin G, H, I and J, together with 21 known compounds, were isolated from the heartwood of Pterocarpus soyauxii. Their structures were determined by the NMR and MS spectral data in comparison with literature data. Compounds (1-25) did not show cytotoxicity against three human cancer cell lines, A549, Panc-28, and HCT-116 (Gl50 > 50 μM).
