title: [Studies on flavonoid constituents of Caragana intermediia].
abstract: OBJECTIVE
  To study the chemical constituents of Caragana intermedia.
  
  
  METHODS
  The compounds were separated by chromatography methods, their structures were identified by spectral analysis.
  
  
  RESULTS
  Ten compounds were isolated and identified as 5,7,4'-trihydroxy-3,3'-dimethoxyflavone (1), 3,5,7,8,4'-pentahydroxy-3'-methoxyflavone(2), puercetin(3), limocitrin(4), 5,7,3',4'-tetrahydroxy-3-methoxyflavone(5), 7,3',5'-trihydroxyflavanone(6), 5,7,3',4'-tetrahydroxy-3,8-dimethoxyflavone(7), butein(8), liquiritigenin(9) and 5,7,4'-trihydroxy-3,8-dimethoxyflavone(10).
  
  
  CONCLUSIONS
  Compound 6 is a new compound and the others were obtained from this plant for the first time.
