摘要:

建立了高效液相色谱法测定染发产品中15种限用染料的分析方法。样品经无水乙醇和水(V无水乙醇V=6∶4)的混合溶液超声提取,使用色谱柱Welch Xtimate-C18(4.6 mm×250 mm,5 µm)经过梯度洗脱分离,流动相为乙腈-0.02 mol/L乙酸铵溶液,流速为1.0 mL/min,检测波长为230 nm,二极管阵列检测器检测。15种染料成分在相应的质量浓度范围内线性关系良好,线性相关系数R2>0.995;检出限为0.86~7.63 μg/g;平均回收率为85.42%~114.61%,相对标准偏差(RSD)为0.72%~8.65%。该方法简便、快速、测定结果可靠,适用于染发剂中15种限用染料成分的定量检测。

Abstract:

The aim of the study was to establish a detection method for determination of 15 kinds of dyestuffs in hair dyes by high performance liquid chromatography(HPLC). The 15 kinds of dyestuffs were extracted with the mix of ethanol and water(Vethanol Vwater=6∶4) by the ultrasonic extraction method. The separation was performed on a Welch Xtimate-C18 column(4.6 mm×250 mm,5 μm) by gradient elution with the solution of 0.02 mol/L ammonium acetate and acetonitrile and determined by photo-diode array detector. The flow rate was 1.0 mL/min and the detection wavelength was 230 nm. The results indicate that each compound shows good linearity in its own concentration range with the correlation coefficient of R2>0.995.The limits of detection(LOD) are in the range of 0.86-7.63 μg/g. The average recoveries are ranged from 85.42% to 114.61%, and the relative standard deviation(RSD) is in the range of 0.72% to 8.65%. The method is simple, rapid, reliable and accurate, which is suitable for determination of 15 kinds of restricted dyestuffs in hair dyes.
