建立了全血中扎来普隆及其代谢产物5-氧扎来普隆和脱乙基扎来普隆超高效液相色谱-三重四级杆质谱(UPLC-TQ/MS)快速检验方法。采用改良后的QuEChERS前处理方法,全血样品用0.1%甲酸-乙腈提取,经无水MgSO4脱水净化,Waters BEH C18色谱柱分离,0.1%甲酸和0.1%甲酸-乙腈进行梯度洗脱。采用电喷雾电离,正离子(ESI+)模式扫描,多反应监测(MRM)模式检测。扎来普隆及其代谢产物在0.5~100 ng/mL范围内线性关系良好(R2≥0.997),回收率为92.0%~100.1%,相对标准偏差为1.9%~5.3%,方法检出限(S/N=3)均为0.05 ng/mL,定量限(S/N=10)在0.1~0.5 ng/mL范围内。
