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.
