title: [Study on quality of medicinal material of Thesium chinense].
abstract: OBJECTIVE
  To study the quality of medicinal material of Thesium chinense.
  
  
  METHODS
  The active ingredients of total flavonoids, kaempferol, mannitol, polysaccharides were selected as the evaluative indicators to comprehensively evaluate the quality of medicinal material of T. chinense.
  
  
  RESULTS
  The total flavone 3.38%, kaempferol 0.984 7 mg x g(-1), mannitol 6.12%, polysaccharides 14.08% and water soluble extract 30.28% were measured in the sample of T. chinense. There was a certain correlation among these selected active ingredients. The compositions of most biological activities component in T. chinense of different populations were similar, but the contents were different significantly. The content of activities component in T. chinense showed a general tendency of declining during growth period and with the increase time of storage.
  
  
  CONCLUSIONS
  Flavone, kaempferol, mannitol, polysaccharides should be selected as the indicators to evaluate the quality of medicinal material of T. chinense.
