摘要: 建立了一种简便、灵敏的测定血浆中曲他维啉的高效液相层析方法.血浆中曲他维啉在碱性条件下被乙醚提取,然后用0.1mol/L盐酸反提取.10μL提取液进C18柱,检测波长254nm,流动相为0.02mol/L磷酸二氢钠∶甲醇=30∶70,高氯酸调pH至2.8.曲他维啉与血浆中其他组分和内标能很好分离.本方法具有良好的线性关系,相对标准偏差小于15%,检出下限(信号噪声比=3∶1)为8μg/L,回收率80%~100%.此方法可用于曲他维啉的药代动力学研究及诊断检测.

Abstract: A simple and sensitive HPLC method for the determination of drotaverine in human plasma has been developed. Drotaverine in alkalinized plasma was extracted with aether solvent and the drotaverine in the aether phase was back-extracted into 0.1 mol/L HCl. 10μL of the aqueous layer was injected into the C18-column and the eluent was monitored at 254 nm. Separation was performed on the column with 0.02 mol/L sodium dihydrogen phosphate-methanol(30∶70)containing perchlorate at pH 2.8 as mobile phase. Drotaverine was well resolved from the plasma constituents and internal standard. An excellent linearity was observed between peak-height ratios and plasma concentrations and the RSD was always <15%. The lowest limit of detection(signal-to-noise ratio 3∶1)was 8 μg/L, the recovery rate was between 80%~100%. The method is suitable for therapeutic monitoring and pharmacokinetic studies of drotaverine in humans.
