Two new neoflavonoids, 3′-hydroxymelanettin and 3′-hydroxy-2,4,5-trimethoxydalbergiquinol, were isolated from the heartwood of Dalbergia odorifera, together with the known compounds, dalbergin, melanettin, stevenin, 4-methoxydalbergione, and cearoin. The structures of the new compounds were established by spectral methods, especially 2D NMR. The 13C assignments using HMQC and HMBC experiments were reported for all compounds.
