摘要： 建立了一种测定染发剂中非那西丁的超高效液相色谱(UPLC)分析方法。染发剂样品经体积分数为70%的甲醇水溶液提取,再用正己烷进行反萃取后,采用BEH C18色谱柱,以乙腈-水为流动相进行梯度洗脱分离,结合保留时间和光谱图定性,以标准曲线定量。实验结果表明:非那西丁质量浓度在0.5～50.0 mg·L-1内与峰面积线性关系良好,相关系数大于0.999 3;方法检出限(S/N=3)为3.0 mg·kg-1;加标量为10,20和50 mg·kg-1时,平均回收率为85.6%～97.9%,相对标准偏差(RSD,n=6)为3.7%～5.3%。

Abstract: An analysis method was established to determine phenacetin in hair dye by ultra-high performance liquid chromatography with a diode array detector (UPLC-PDA).The hair dye sample was extracted with 70% (volume fraction) methanol-water solution,reverse extracted with n-hexane,and analyzed by UPLC-PDA on a BEH C18 column,with acetonitrile-water as the mobile phase in gradient elution mode.The targets were qualitatively determined by retention time,confirmed by the ultraviolet spectrum,and quantified by standard graph.Test results indicated that in the phenacetin mass concentration range of 0.5-50.0 mg·L-1,the content shows a good linearity with the peak value with correlation coefficient (r) higher than 0.999 3.The detection limit of phenacetin is 3.0 mg·kg-1.When the spiking level is 10,20 and 50 mg·kg-1,the spiked recoveries of phenacetin are ranged within 85.6% and 97.9%,and the precision (RSD) ranges from 3.7% to 5.3% (n=6).

Key words: hair dye, ultra-high performance liquid chromatography, phenacetin
