title: [Studies on flavonoids from Aquilegia oxysepala Trautv. et Mey].
abstract: OBJECTIVE
  To study the chemical constituents in Aquilegia oxysepala.
  
  
  METHODS
  Various chromatographic techniques were used to separate and purify the constituents. The structures were determined by spectral analysis and chemical evidence.
  
  
  RESULTS
  Five flavonoids were isolated from the plant and identified as genkwanin, apigenin, luteonlin, swertisin and tilianin.
  
  
  CONCLUSIONS
  All these compounds were isolated from the plant for the first time.
