Abstract:
A new isoflavanone, 2,2'-epoxy-4'-methoxy-3,7-dihydroxyisoflavanone (1), and a new natural coumaranone, 2-hyroxy-2-(4'-methoxybenzyl)-6-methoxy-3-coumaranone (2), along with 26 known compounds, were first isolated from the trunk of Horsfieldia pandurifolia. Their structures were elucidated by the means of spectroscopic analysis. Compound 1 was assessed for its cytotoxicity against five human tumour lines (HL-60, SMMC-7721, A-549, MCF-7 and SW-480), and the result showed that it has no activity.
