Two new isoflavonoids, 6-methoxy-5,7,8,4-tetrahydryoxyisoflavone (1) and 4-methoxy -5,6-dihydroxyisoflavone-7-O-β-D-glucopyranoside (2), were isolated from the rhizomes of Belamcanda chinensis (L.) DC.Their structures were elucidated by extensive spectroscopic evidence including 1D NMR, 2D NMR, MS and IR spectra.
