New isoflavones from Iris kashmiriana.
Phytochemical investigation of the rhizomes of Iris kashmiriana (Iridaceae) led to the isolation of three isoflavones characterized by 1D and 2D NMR, IR, UV, and MS as 4'-hydroxy-8-methoxy-6,7-methylenedioxyisoflavone (isonigricin, 1), 5,6-dihydroxy-4',7-dimethoxyisoflavone (isoirisolidone, 2), and 5,7-dihydroxy-4',6-dimethoxyisoflavone (irisolidone, 3). Compound 1 is a new isoflavone, while 2 is reported for the first time from a natural source.
