Two new isoflavone glycosides, dalspinosin 7- O-β-D-apiofuranosyl-(1→6)-β-D-glucopyranoside (1) and caviunin 7- O-(5- O-trans-p-coumaroyl)-β-D-apiofuranosyl-(1→6)-β-D-glucopyranoside (2), and two known compounds, caviunin 7- O-β-D-apiofuranosyl-(1→6)-β-D-glucopyranoside (3) and caviunin (4) were isolated from the stems of Dalbergia vietnamensis. Their structures were determined by the combination of spectroscopic and chemical methods, including 1D- and 2D-NMR spectroscopy, as well as by comparing with the NMR data reported in the literature.
