Bioassay-guided investigation of the stems of Maackia fauriei led to the isolation of seven flavonoid constituents, formononetin (1), genistein (2), daidzein (3), texasin (4), tectorigenin (5), odoratin (6) and mirkoin (7). Their structures were elucidated on the basis of spectral studies as well as
OBJECTIVE

METHODS
Silica gel column chromatography and Sephadex LH-20 were employed to separate, and the compounds obtainedere elucidated by means of UV, IR, MS, 1H NMR, 13C NMR.
