摘    要:采用两种不同的色谱条件测定吡喹酮注射剂中吡喹酮的含量,色谱柱为迪马DiamonsilC18(4.6mm×250mm,5μm)柱,流动相为甲醇-水及乙腈-水,检测波长为263nm及210nm,流速1mL/min。结果显示,在两个不同的检测范围内,线性关系均良好(分别为r=0.9998和r=0.9996),吡喹酮的平均回收率为100.38%和99.90%,RSD=1.13%和1.1%(n=9)。两种方法简便易行,精密度、回收率、重现性均符合要求。结果表明,两种方法均可用于吡喹酮注射剂的含量测定。

关 键 词:吡喹酮注射剂  高效液相色谱法  含量测定

Abstract:To establish two HPLC method for determining the content of PZQ in the injection. The DIKMA Diamonsil C18 (4.6 mm×250 ram, 5μm) Column was adopted. The mobile phase was V(methanol) : V(water)and V (acetonitrile): V (water), the detective wavelength was 263 nm and 210nm, the flow rate was 1 mL/min. The two methods were both linear within r = 0. 999 8/0. 999 6. The mean recovery was 100.38% and 99.90%, RSD = 1.13% and 1.1% (n = 9). They turned out to be convienient method with good precision. These results showed that two methods both could be used to determine the content of PZQ in the injection.
Keywords:PZQ injection  HPLC  determination of the content
