Abstract


The plants of the Dalbergia genus have been used for a long time in Vietnamese traditional medicine. In our continuing study on the chemical constituent and biological activities of medicinal plants, a phytochemical investigation of the methanol extract of Dalbergia tonkinensis led to the isolation of two isoflavones (1, 2) and a dihydrophenanthrene (3). Their structures were identified by spectroscopic methods including ESI-MS, 1D- and 2D-NMR in comparison with the literature. Compound 3 was found for the first time from the Dalbergia species.
