ISOLATION AND STRUCTURAL DETERMINATION OF ISOFLAVANONES FROM DALBERGIA TONKINESIS PRAIN COLLECTED IN DAK LAK
Keywords:Dalbergia tonkinensis, Fabaceae, flavonoids, wood
From the ethyl acetate extract of the wood of Dalbergia tonkinensis Prain, was collected in Buon Ma Thuot city, DakLak provice, two isoflavanones sativanone (1), and 3’-O-methylviolanone (2) were isolated. The chemical structure of these compounds were determined by the interpretation of NMR spectral data and comparison with published data. This is the first time they are reported from wood of Dalbergia tonkinensis.
