Irifloside (III), C_<23>H_<22>O_<12>・H_2O, mp 177-178°, a new isoflavone glycoside, has been isolated from the rhizoma of Iris florentina L. (Iridaceae) together with iriflophenone (II), irisolone (IV), irisflorentin (I), iristectorigenin B (V), irigenin (VI) and iridin (VII). The structure of irifloside (III) has been determined as 5,4'-dihydroxy-3'-methoxy-6,7-methylenedioxyisoflavone-4'-O-β-D-glucoside by chemical degradation and spectral means, and its aglycone, C_<17>H_<12>O_7,mp 221-223°, was named iriflogenin (VIII). The structure of iriflophenone (II), C_<13>H_<10>O_5,mp 207-208°, has been determined as 2,4,6,4'-tetrahydroxybenzophenone by spectral means.
