A high-performance liquid chromatographic method for the determination of promazine in human plasma is described. The assay involves a single-step liquid-liquid extraction using pentane-2-propanol (98:2, v/v). The analyte of interest and the internal standard chlorpromazine were separated on a Spherisorb CN column using a mobile phase of acetonitrile-50 mM ammonium acetate (9:1, v/v). Electrochemical detection was achieved using an applied potential of +750 mV. The assay was validated according to international requirements prior to application to a pharmacokinetic study and was found to be specific, accurate and precise with a linear range of 0.25-25 ng ml(-1).
本文描述了一种测定人血浆中丙嗪的高效液相色谱法。该测定方法包括使用戊烷 - 2 - 丙醇(98:2,v/v)进行单步液 - 液萃取。目标分析物和内标氯丙嗪在Spherisorb CN柱上分离,流动相为乙腈 - 50 mM醋酸铵(9:1,v/v)。通过施加 +750 mV的电位实现电化学检测。该测定方法在应用于药代动力学研究之前根据国际要求进行了验证,结果表明其具有特异性、准确性和精密度,线性范围为0.25 - 25 ng ml⁻¹。
