Determination of safflor yellow A by RP-HPLC and resources quality comparison in Carthamus tinctorius / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To provide the basis for establishing evaluation criterion, selecting good strains and carring out good agricultural practice of the crude drug.</p><p><b>METHOD</b>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.</p><p><b>RESULT</b>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.</p><p><b>CONCLUSION</b>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.</p>
