title: [Isolation and structure identification of a new isoflavone from Psoralea corylifolias].
abstract: OBJECTIVE
  To study the chemical constituents of the fruits of Psoralea corylifolia L.
  
  
  METHODS
  The constituents were separated and purified by column chromatography with normal phase silica gel and polyamide. Their structures were identified on the basis of physical and spectral data (MS, NMR, HMBC and HMQC).
  
  
  RESULTS
  Six compounds were isolated and identified as psoralen (1), isopsoralen (2), bavachalcone (3), psoralidin (4), daidzin (5) and bavadin (6).
  
  
  CONCLUSIONS
  Compound 6 is a new compound. Compound 5 was isolated from this plant for the first time.
