Abstract

Two new isoflavones, 6, 3′, 4′-trimethoxy-7, 8, 5′-trihydroxyisoflavone (1), 7, 4′-dimethoxy-8, 3′, 5′-trihydroxy-6-O-β-D-glucopyranosylisoflavone (2), and 5, 3, 3′-trihydroxy-7, 4′-dimethoxyflavanone (3) have been isolated from the underground parts of Iris potaninii along with known isoflavones (4—8) and iriflophenone (9). The structures of the new compounds were determined using NMR and mass spectroscopic methods.
