| 摘 要： | 文中建立了HPLC-DAD同时测定头发中碱性橙31等9种碱性染料的方法。方法以甲醇为提取溶剂，采用xB—c18柱，以乙腈-0．02mol／L乙酸铵（含0．05％甲酸）为流动相进行梯度洗脱，二极管阵列检测器检测。试验的平均回收率为93．9％～102．5％，相对标准偏差为1．2％～3．5％，最低检测浓度为0．15～0．60mg／kg。结果表明该方法前处理简单、快速，适用于测定头发中碱性橙3l等9种碱性染料组分的含量。

| Abstract: | A HPLC-DAD method of simultaneous determination of 9 basic dyes in hair was developed. Hair samples were subject to extraction using methanol, the exact was performed on a XB-C18 column with a diode array detector of acetonitrile-0.02mol/L ammonium acetate（contain 0.05%（v/v） formic acid）. Recovery rates with 9 basic dyes were in the range of 93.9%-102.5%,with the RSD of 1.2%- 3.5%.The minimum detectable concentration was 0.15-0.60 mg/kg. The results show that the method is simple, rapid, and suitable for the determination of 9 basic dyes＇ content. |
