摘要: 建立了人尿中氯喹的定性定量分析方法,2ml尿样用2ml×2环己烷:乙酸乙酯(8:2)提取净化后,60℃水浴室气吹干,残留物定容溶解后,气相色谱分析,氯喹的保留时间为9.44min。方法最低检测限为200ng/ml,回收率为87.0%,RSD=7.9%(n=5),在0~50μg/ml浓度范围内,有良好的线性关系:A=1778.9+13686C,r=0.999。方法同时可用于血中氯喹的分析。附一例应用报告,测得尿中氯喹的含量为0.745mg/ml,血中氯喹的含量为3.68μg/ml。尿液中同时检出氯喹的N-去单已基代谢物。定性结果经质谱法验证。

Abstract: A GC method was established for qualitative and quantitative determination of chloroquine in human urine. The chloroquine is extracted from 2ml urine with 2 x 2ml cyclohexame: chloroform (8: 2). The retention time of chloquine is9.44min. The linear of quantitation is 0 - 50μg /ml. Therecovery of the procedure in 25μg g/ml is 87 .0%, CV = 7.9% (n = 5). The limit of the determination is 200ng/ml.The method can also be used in blood. A case is reportedhere. In that, we detected chloroquine in urine and blood.The quantitation of chloroquine in urine and blood is 0. 475mg/ml and 3 .68μg/ml, respectively. A metabolite of chloroquine - desethylchloroquine is also found in the urine.
