[Studies on chemical constituents of Maackia amurensis Rupr. et. Maxim].
OBJECTIVE
To study the chemical constituents of EtOH extract from heartwood of Maackia amurensis.


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.


RESULTS
4', 8-dihydroxyl-7-methoxylisoflavone (I), tectorigenin(II), glycitein(III) and resveratrol (IV) were isolated and identified.


CONCLUSIONS
Among them, Compound I was a new isoflavone and compound III was obtained from M. amurensis for the first time.
