测定左旋吡喹酮血药浓度的反相高效液相色谱法
摘要
本文建立了测定左旋吡喹酮血药浓度的高效液相色谱分析方法.以ODS-C
18
化学键合相(5μm)作为固定相
甲醇:水(7:3V/V)作为流动相;用吡喹酮的衍生物作为内标准品.采用紫外检测器(λ=220nm)
得出检出限为2.5ng
最低检出血药浓度为0.012μg/ml血清
线性范围为0.012~1.6μg/ml血清(γ=0.999)
方法回收率为93.4~97.2%.本法简便、灵敏、专一、重现性好
适用于左旋吡喹酮血药浓度测定及药物动力学研究
Abstract
A HPLC method for quantitative determination of levopraziquantel in serum was described. A RP ODS-C18 (5μm) column fitted with a UV detector at 220 nm was used for analysis. The mobile phase used was methanol-water (7:3v/v). The analogue of praziquantel was used as an internal standard. The minimum detectable limit was 2.5ng. Assay linearity was demonstrated over the range of 0.012-1.6μg/ml of serum (r=0.999). The recovery ofthe method was 93.4-97.2%. This method was simple
precise
and sensitive
and had been used in the pharmacokinetic study and the clinical determination of levopraziquantel in serum.
