摘要: 本试验旨在建立一种同时测定复方吡喹酮浇泼剂中吡喹酮和乙酰氨基阿维菌素含量的HPLC方法.色谱条件为 C18柱(250 mm×4.6 mm,5 μm),柱温30 ℃,流动相为乙腈-水-三氟乙酸(70:30:0.01),流速1.0 mL/min,进样量20 μL,检测波长245 nm.吡喹酮在0.7506~7.5063 mg/mL范围内,乙酰氨基阿维菌素在31.266~312.660 μg/mL范围内线性关系均良好,相关系数(r)均为0.9999,平均回收率分别为99.0%、98.1%,RSD分别为1.02%、0.32%.本试验所建立的HPLC法快速简便、准确可靠,可用于复方吡喹酮浇泼剂中吡喹酮和乙酰氨基阿维菌素含量的测定.

Abstract: The assay was aimed to establish the method to simultaneously determine praziquantel (PZQ) and eprinomectin (EPR) contents of compound praziquantel pour-on preparation by HPLC in single wavelengths. The chromatographic conditions were as follows, C18 column (250 mm×4.6 mm, 5 μm) with a column temperature of 30 ℃, the mobile phase was consisted of acetonitrile-water-trifluoroacetic acid (70:30:0.01) with a flow rate of 1.0 mL/min, and the detection wavelength was set at 245 nm. The results showed that the linear relation of PZQ was good in the linear range between 0.7506 and 7.5063 mg/mL, the linear relation of EPR was good in the linear range between 31.266 and 312.660 μg/mL, related coefficients were both 0.9999, and the average recovery was 99.0% with RSD 1.02% and 98.1% with RSD 0.32%, respectively. The established HPLC method was quick, simple, accurate and reliable, and could be applied to determine the PZQ and EPR contents of compound praziquantel pour-on preparation.
