title: [Chemical constituents from the flower of Paulownia fortunei( seem. ) Hemsl].
abstract: OBJECTIVE
  To study the chemical constituents of the flower of Paulownia fortunei (Seem.) Hemsl.
  
  
  METHODS
  The constituents were isolated by column chromatography and their structures were elucidated through spectroscopic analysis.
  
  
  RESULTS
  The compounds were identified as diplacone( I ) ,3 '-O-methyldiplacone ( II ) , mimulone ( ll) , ursolic acid( IV ), beta-sitosterol ( V ), daucosterol ( VI).
  
  
  CONCLUSIONS
  All these compounds were obtained from the flower for the first time.
