title: New isoflavones from Iris kashmiriana.
abstract: 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.
