Abstract: 目的:建立同时检测Beagle犬血浆中四氢巴马汀、脱氢紫堇碱、小檗碱和巴马汀的分析方法,并应用有机溶剂沉淀法提取含药血浆中的成分.方法:采用C18反相柱,流动相为乙腈-0.1%甲酸水溶液梯度洗脱,质谱采用多反应监测(MRM)方式进行正离子检测.结果:定量分析的离子对(m/z)为:366.2/350.2(四氢巴马汀)、356.2/191.2(脱氢紫堇碱)、336.2/320.2(小檗碱)和352.2/336.2(巴马汀).测定血浆中四氢巴马汀、脱氢紫堇碱和小檗碱的线性范围均为0.0488~50 μg·L-1,巴马汀为0.0488~100μg· L-1,这4种成分的定量下限均为0.0488 μg· L-1,该方法的精密度、准确度和稳定性均符合要求.结论:该法选择性强、灵敏度高、操作简便,可用于血浆中这4种生物碱的药代动力学研究.
