title: [Chemical constituents from branch of Broussonetia papyrifera].
abstract: OBJECTIVE
  To investigate the chemical constituents from the branch of Broussonetia papyrifera.
  
  
  METHODS
  Column chromatographic methods were used to isolate the chemical constituents. ESI-MS and NMR methods were employed for their structural elucidation.
  
  
  RESULTS
  Six compounds were isolated and identified as (2S)-7, 3'-dihydroxy-4'-methoxyflavan (1), ergosterol peroxide (2), D-galacitol (3), sulfuretin (4), liriodendrin (5), graveolone (6), respectively.
  
  
  CONCLUSIONS
  Compounds 1-6 were isolated from the plant for the first time.
