Abstract
目的 建立超高效液相色谱-质谱联用方法快速检测中药制剂中添加的11种化学药物成分(马来酸氯苯那敏、氯雷他定、硝酸咪康唑、盐酸特比萘芬、酮康唑、艾司唑仑、盐酸氯丙嗪、丙酸氯倍他索、醋酸地塞米松、醋酸泼尼松和吲哚美辛).方法 采用Waters ACQUITY UPLC BEH C18 column(2.1 mm×100 mm,1.7 μm);梯度洗脱:流动相A为乙腈,流动相B为5 mmol·L-1乙酸铵(0.1%甲酸)水溶液.通过比较样品峰与对照品峰的保留时间、一级质谱和二级质谱碎片离子,确定样品中是否掺杂化学止痒药物.结果 建立的快速超高效液相串联质谱方法检测上述化学药物成分不受药物辅料干扰,各色谱峰分离良好,11种待测成分最低检出限为0.01~0.46 ng·mL-1.结论 该方法简便、灵敏度高,可快速有效地判断中药制剂中是否非法掺入上述化学药品.
