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Diamonsil C18(4.6×250,5μm)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=0.9998/0.9996),吡喹酮的平均回收率为100.38%和99.90% ,RSD=1.13%和1.1%。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。 |

Abstract: |
To establish two HPLC method for determining the content of PZQ in the injection.The DIKMA Diamonsil C18 (4.6×250, 5μm) Column was adopted.The mobile phase was V(methanol):V(water)and V(acetonitrile):V(water),the detective wavelength was 263nm and 210nm,the flow rate was 1mL/min.The two method were both linear within(r=0.9998/0.9996).The mean recovery was 100.38% and 99.90%,RSD=1.13% and1.1%(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. |
