摘要
目的:建立小鼠组织中KS0604的定量分析方法。方法:采用组织消化结合基于离子交换和反相分配原理的两步固相萃取法,并采用无胶筛分毛细管电泳技术测定小鼠组织中的KS0604。结果:小鼠肾组织中KS0604在2.0~2000μg·g^(-1)范围内呈良好线性,最低定量限LOQ为2.0μg·g^(-1);其他组织中KS0604在1.3~128μg·g^(-1)范围内呈良好线性,最低定量限LOQ为1.3μg·g^(-1);r>0.999。加样回收率试验RSD<10.82%,精密度试验RSD<2.3%,稳定性试验结果表明KS0604在小鼠组织中的稳定性良好。结论:该方法可用于定量检测小鼠组织中的KS0604。
Objective:To establish a method for the quantitative determination of KS0604 in the mouse tissues.Method:A dual solid phase extraction(SPE) pretreatment method coupling with non-gel sieving capillary electrophoresis(NGCE) was established to determine the content of KS0604 in the tissues of mice.Result:The calibration curve of KS0604 was linear within the concentration range of 2.0-2 000μg ? g^(-1) in kidney and 1.3-128μg ? g^(-1) in the other mouse tissues with correlation coefficients(r) above 0.999. The LLOQ was 2.0μg ? g ^(-1) in kidney and 1.3μg ? g ^(-1) in the other mouse tissues.The RSD of the sample-adding recovery of KS0604 in mouse tissues was less than 10.82%and the precision RSD of the assay was below 2.3%.KS0604 was stable in mouse tissues. Conclusion:The combined method of solid-phase extraction and NGCE can be used in the detection and quantitative determination of KS0604 in mouse tissues.
