From the methanol extract of the heartwood of Dalbergia tonkinensis Prain collected in Buon Ma Thuot city, DakLak province, five flavonoids, liquiritigenin (1), 7,3',5'-trihydroxyflavanone (2), sativanone (3), 3'-O-methylviolanone (4) and sulfuretin (5) were isolated. The chemical structures of isolated compounds were determined by the interpretation of NMR spectral data as well as comparison with data from the literature. This study marks that 7,3',5'-trihydroxyflavanone (2) was isolated from the genus Dalbergia for the first time.
