A new isoflav-3-ene, 2,2′-dimethoxy-7-hydroxy-4′,5′-methylenedioxyisoflav-3-ene (2-methoxyjudaicin), has been isolated from the roots of Cicer bijugum. The structure was determined by NMR spectroscopy and FAB-mass spectrometry. Chromatographic and mass spectral data indicate that this isoflav-3-ene is also present in the plant as a glycoside.
