Abstract

建立了固相萃取-超快速液相色谱-串联质谱法(SPE-RRLC-MS/MS)同时测定化妆品中9种抗过敏药物残留(多西拉敏、美沙吡林、曲吡那敏、溴苯那敏、苯海拉明、赛克利嗪、二苯拉林、羟嗪和氯苯沙明)的方法。试样经三氯乙酸溶液超声提取、离心、Plexa PCX柱净化后,以甲醇-0.1%甲酸溶液(含5 mmol/L甲酸铵)为流动相,用RRLC进行分离。在电喷雾正离子模式下,以选择反应监测(SRM)方式采集数据进行定性与定量分析。9种药物在1.0~50.0!g/L范围内均呈良好的线性关系,相关系数均大于0.99;在2.0,5.0和20.0!g/kg3个浓度加标水平下的平均回收率为90.6%~103.5%;相对标准偏差(RSD,n=6)为2.5%~6.0%;检出限为0.3~0.6!g/kg,定量限为1.0~2.0!g/kg。
