title: [Studies on chemical constituents of Erythrina arborescens Roxb].
abstract: OBJECTIVE
  To study the chemical constitutes in Erythrina arborescens.
  
  
  METHODS
  Various chromatographic techniques were used to isolate and purify the constituents. The structures were elucidated by spectral analysis and chemical evidence.
  
  
  RESULTS
  Six compounds were isolated from the plant and identified as alpinumisoflavone, wighteone, daidzein, genistein, vittadinoside and stigmasterol.
  
  
  CONCLUSIONS
  All these compounds were isolated from the plant for the first time.
