title: [Chemical constituents of the leaves of Crataegus scabrifolia (Franch.) Rehd].
abstract: OBJECTIVE
  To explore the medicinal resources of Crataegus and seek compounds with pharmaceutical effects.
  
  
  METHODS
  Column chromatography was employed for the isolation and purification of constituents and the structures were elucidated by spectral analysis and chemical evidence.
  
  
  RESULTS
  Six compounds were obtained and identified as rutin, hyperoside, vitexin, ursolic acid, daucosterol, and nonacosanol.
  
  
  CONCLUSIONS
  The main constituents of the leaves of Crataegus scabrifolia are flavonoids.
