摘要: 目的: 建立同时测定人血浆中氮烯菲林及其代谢产物的反相高效液相色谱法。 方法: 血样在加入内标后用乙酸乙酯进行两次萃取, 然后以反相柱分离, 在 345 nm 处以紫外检测器进行检测。 结果: 血样中没有明显的干扰峰出现, 氮烯菲林及其代谢产物洗脱快, 分离好, 线性范围分别为 0.05 ~40 mg·L-1, 0.1 ~ 20 mg·L-1 , 最 低 检 测 限 为0.05 mg·L-1 , 相对回收率为 81.42%~ 104.67%, 变异系数小于 9.95 %。结论:: 本法快速、 灵敏、回收率高, 且萃取过程简单, 可用于氮烯菲林的药代动力学研究。

Abstract: AIM: To develop a method to determin- ing etheofazine(EDMTP) and its metabolite etheotriazene (EDMTP-Ⅱ) by HPLC in human plasma.METHODS: Human plasma samples containing etheofazine(EDMTP) and its metabolite EDMTP-Ⅱ after addition of internal standard (IS) , was extracted with ethylacetate and sepa- rated in a reversed-phase ODS column, and the detection was achieved at 345 nm by ultra-violet (UV).RESULTS: The limit of detection was 0.05 mg·L-1 for both etheofazine(EDMTP) and its metabolite EDMTP-Ⅱ. No potential interference was found.The method provided recoveries up to 81.42%-104.67%and accepted coef- ficients of variation were found for both within-run (<9.95%) and day-to-day (<9.14%) assays.CONCLUSION: This method is rapid, sensitive and simple for studying the pharmacokinetics of EDMTP and its metabolite EDMTP-Ⅱ .
