title: [Flavones from flowers of Paulownia fortunei].
abstract: OBJECTIVE
  To study the flavones of the flowers of Paulownia fortunei.
  
  
  METHODS
  The constituents were isolated by column chromatography and their structures were elucidated through spectroscopic analysis.
  
  
  RESULTS
  The compounds were identified as: 3'-O-methyldiplacol (1), 6-geranyl-3, 3', 5, 7-tetrahydroxy-4'-methoxy flavanone (2), homoeriodictyol (3), 5, 7, 4'-trihydroxy-3'-methoxy flavone (4), 3'-methoxyluteolin-7-O-beta-D-glucoside (5), apigenin-7-O-beta-D-glucoside (6), kaempferol-7-O-beta-D-glucoside (7), quercetin-3-O-beta-D-glucoside (8), kaempferol-3-O-beta-D-glucoside (9), quercetin-7-O-beta-D-glucoside (10), luteolin-7-O-beta-D-glucoside (11).
  
  
  CONCLUSIONS
  All these compounds were obtained from the flowers for the first time.
