title: [Studies on chemical constituents of Maackia amurensis Rupr. et. Maxim].
abstract: 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.
