title: [Chemical constituents from leaves of Paulownia fortunei].
abstract: OBJECTIVE
  To study the chemical constituents of leaves 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 mimulone (I), apigenin (II), luteolin (III), 2alpha, 3beta, 19beta-trihydroxyurs-28-O-beta-D-galactonopyranos ylester (anserinoside, IV), 3alpha-hydroxyl-ursolicacid (V), ursolicacid (VI), daucosterol (VII), beta-sitosterol (VIII).
  
  
  CONCLUSIONS
  The compounds I - V are obtained from leaves of Paulownia fortunei (Seem.) Hemsl for the first time.
