%X A new isoflavone and two compounds with similar structures, namely 5, 7, 3′-trihydroxy-6, 2′, 5′-trimethoxyisoflavone, 5, 7, 3′-trihydroxy-6, 4′, 5′-trimethoxyisoflavone (irigenin) and its glucoside (iridin), were isolated from Belamcanda chinensis. The structures of these compounds were determined by 1H  and 13C NMR spectroscopy. The structure of the new isoflavone was further verified by combined use of mass spectroscopy and 2D NMR techniques including HMBC, HSQC and NOESY.
