title: [Chemical constituents from rhizomes of Iris germanica].
abstract: Twenty-one compounds were isolated from the rhizomes of Iris germanica by various chromatographic techniques such as silica gel, ODS and Sephadex LH-20 chromatography. Their structures were established on basis of physical properties, MS and NMR spectroscopic data Their structures were identified as ombuin (1), 5, 3, 3'-trihydroxy-7, 4'-dimethoxyflavanone (2), naringenin (3), cirsiliol-4'-glucoside (4), 3beta, 4'-dihydroxy-7,3'-dimethoxyflavonone-5-O-beta-D-glucopyranoside (5), genistein (6), irilin D (7), muningin (8), 5, 7, 4'-trihydroxy-6, 3', 5'-trimethoxyisoflavone (9), tectorigenin (10), irigenin (11), tectoridin (12), iridin (13), mangiferin (14), irisxanthone (15), pyroglutamic acid (16), 2, 4', 6-trihydroxy-4-methoxybenzophenone-2-O-beta-D-glucoside (17), apocynin (18), androsin (19), beta-sitosterol (20), and daucosterol (21). Among them, compounds 1-9, 16, 17 were obtained from this plant for the first time, compounds 8 and 9 were separated from Iris species for the first time, compounds 1, 4, and 17 were obtained from the family for the first time.
