摘 要:建立了一种超高效液相色谱-串联质谱(UPLC-MS/MS)的方法用来测定化妆品中环吡酮胺的含量。使用沃特世超高效液相色谱C18色谱柱(1.7μm×2.1 mm×50 mm),以甲醇/水(含0.1%甲酸)溶液为流动相进行梯度洗脱,流速设定为0.5 mL/min,进样量设置为2μL,在电喷雾正离子模式下(ESI^(+)),采用多反应监测(MRM)模式进行定性和定量测定。结果表明,建立的分析方法在所研究的范围内浓度和峰面积具有良好的线性关系,相关系数为0.999 6,平均加标回收率为107.9%(n=3),平均相对标准偏差(RSD)为4.80%(n=6),检出限浓度为0.066 8 mg/kg,定量限浓度为0.223 mg/kg,该方法方便、灵敏、准确,适用于化妆品中环吡酮胺的含量检测与质量监督。An UPLC-MS/MS method for the determination of ciclopirox olamine in cosmetic samples has been developed.The UPLC separation was carried out on a Waters Acquity UPLC^(®) BEH C_(18) column(1.7 μm×2.1 mm×50 mm) by gradient elution using methanol/water(containing 0.1% formic acid) system.The flow rate is 0.5 mL/min and sample injection amount is 2 μL.The electrospray ionization source in positive ion mode(ESI^(+)) was used for qualitative analyzing and quantitative analyzing of ciclopirox olamine in the multiple reaction monitoring(MRM) mode.The developed method has a good linear relationship between concentration and peak area in the corresponding concentration range.The linear correlation coefficient is 0.999 6,and the average recoveries of standard addition is 107.9%(n=3),and the average relative standard deviation is 4.80%(n=6),the limit of detection is 0.066 8 mg/kg,and the limit of quantification is 0.223 mg/kg.The method is convenient,sensitive and accurate,and the good analytical features of the proposed method make it useful to carry out the quality control of cosmetic products and raw materials to assure the safety of users.
