概要
OBJECTIVE
To study the chemical constituents in the rhizoma of Iris dichotoma.
METHODS
The chemical constituents were isolated by various column chromatographic methods. The structures of the compounds were elucidated on the basis of physiochemical properties and spectral analysis.
RESULTS
Eleven compounds, hispidulin (1), rhamnocitrin (2), iristectorigenin A (3), 4', 5, 7, 8-tetrahydroxy-6-methoxy isoflavone (4), 6-hydroxybiochanin A (5), iristectorin B (6), iristectorigenin A (7), kaempferol-7-methyl ether (8), tamarixetin-7-glucoside (9), iristectorin A (10), 3', 3, 5-trihydroxy-4', 7-dimethoxy-flavone-3-O-beta-D-galactopyranoside (11) were isolated and identified.
CONCLUSIONS
Compounds 1-11 were obtained from this plant for the first time.
