title: [Determination of safflor yellow A by RP-HPLC and resources quality comparison in Carthamus tinctorius].
abstract: OBJECTIVE
  To provide the basis for establishing evaluation criterion, selecting good strains and carring out good agricultural practice of the crude drug.
  
  
  METHODS
  Representative 22 varieties of Carthamus tinctorius were selected and cultivated in different ecological localities and different years. And the content of safflor yellow A in their corollas were measured by RP-HPLC to compare the differences and their genetic stabilities among varieties.
  
  
  RESULTS
  The range of of safflor yellow A content was 0.70%-1.85% which were varied among varieties (P < 0.01). The content of safflor yellow A in varieties Yutai Honghua, Hefei Honghua, Rucheng Honghua were higher than in others.
  
  
  CONCLUSIONS
  The effective compound safflor yellow A in C. tinctorius was one of the main quality evaluation criterions. Varieties Yutai Honghua, Hefei Honghua and Rucheng Honghua were good resources.
