Abstract
Objective:
To study the chemical constituents of EtOH extract from heartwood of Maackia amurensis.
Method:
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.
Result:
4', 8-dihydroxyl-7-methoxylisoflavone (I), tectorigenin(II), glycitein(III) and resveratrol (IV) were isolated and identified.
Conclusion:
Among them, Compound I was a new isoflavone and compound III was obtained from M. amurensis for the first time.
