title: [Analysis on chemical composition of genus Pueraria stems from China].
abstract: OBJECTIVE
  To provide scientific basis for developing and utilizing Pueraria stems.
  
  
  METHODS
  The contents of total flavonoid were determined by means of UV spectrophotometry. The isoflavones in stems and roots of nine species of genus Pueraria were analyzed by TLC.
  
  
  RESULTS
  The stems and roots are similar in chemical composition.
  
  
  CONCLUSIONS
  Pueraria stems as a potential resource could be used as a substitute for Pueraria roots.
