[Studies on the flavonoids from Lignum Dalbergiae Odoriferae (II)].

Objective: To study the chemical constituents of Lignum Dalbergiae Odoriferae.
Methods: The isolation and purification were carried out by repeated silica gel column chromatography, and the chemical structures were determined by physico-chemical properties and spectral analysis.
Results: Nine compounds were isolated and identified as fisetin (1), luteolin (2), genistein (3), isohemiphloin (4), 6-C-glycopyranosyl luteolin (5), homoeriodictyol (6), liquiritigenin (7), daidzein (8) and naringenin (9).
Conclusion: Compounds 1,4,5,6 are isolated from this plant for the first time.
