摘要: 利用高效液相色谱法,分别检测并对比红花药材中羟基红花黄色素A和金橙Ⅱ的浓度,从而建立对比筛选红花样品中金橙Ⅱ的方法。结果在46个红花样品中,推测有26个可疑阳性样品;而通过对比筛选法能将可疑阳性样品数减至2个。经HPLC-MS法确证了对比筛选法的结果。检测羟基红花黄色素A(HSYA)的色谱条件为:甲醇-乙腈-0.01%磷酸溶液(体积比为26:2:72)为流动相。检测金橙Ⅱ的色谱条件为:乙腈-0.025 mol/L溶液(40:60)为流动相。此法相比于常规只检测红花中金橙Ⅱ的方法,筛选效率与精确度更高,并且更经济、适应性更广。

Abstract: In this study,a HPLC method for contrastively screening of orange II in safflower samples was established by comparing concentrations of HSYA and orange II.For hydroxysafflor yellow A (HYSA) chromatographic testing condition,methanol-acetonitrile-0.01 mol/L phosphoric Acid (26:2:72) was used as mobile phase.For Orange II chromatographic testing condition,acetonitrile -0.025 mol/L monopotassium phosphate (40:60) was used as mobile phase.After testing the concentration of orange II of all 46 safflower samples,26 were indicated as suspicious positive samples.However,the number of suspicious positive samples was reduced to 2 using contrast screening method.The screening results were ensured with LC/MS method.Hence,the results showed that the efficiency of contrast screening method was superior to conventional orange II screening method.
