摘要:

为建立伊维菌素微乳中伊维菌素含量的高效液相色谱(HPLC)测定方法,选用Hypersil ODS2 (5 μm,4.6 mm×250 mm)色谱柱,流动相为甲醇∶乙腈∶水为35∶60∶5(V/V/V),检测波长为244 nm,柱温为30 ℃,流速为1 mL/min进行测定。结果显示,伊维菌素在该色谱条件下,系统适应性良好,在80~320 μg/mL浓度范围内线性关系良好,回归方程为:Y=22 700X+2 510,R2=0.9998,总平均回收率为101.90%±2.94%,RSD为2.88%,对中试生产的3批伊维菌素微乳进行含量测定,RSD为1.86%。表明该含量测定方法准确可靠,重现性好,可用于伊维菌素微乳中伊维菌素含量的测定,并为该新型制剂的质量标准的制定和质量评价提供依据,也为后期的临床安全应用提供可靠的参考。

Abstract:

In order to establish the determination method of ivermectin (IVM) in the ivermectin microemulsion injection by high performance liquid chromatography (HPLC), Hypersil ODS2 colunm (5 μm,4.6 mm×250 mm) was used in this study. The mobile phase composed of methanol, acetonitrile and water (35:60:5,V/V/V) at a flow rate of 1 mL/min. The detection wave length was set at 244 nm and the column temperature was 30 ℃. The results showed that the HPLC system suitability of IVM was good. A good linear correlation of IVM was observed within the concentration range 80 to 320 μg/mL, and the average recovery rate was 101.90%±2.94% with RSD was 2.88%, the regression equation was Y=22 700X+2 510 (R2=0.9998). The RSD of IVM content in ivermectin microemulsion injection was 1.86%. The method was accurate and reliable,reproducible,easy to operate, which could be used in new type of ivermectin microemulsion injection. The method could be used as the basis of quality control and establishing a quality standard, and to provide basis for quality evaluation, also can provide reliable reference for safe veterinary clinical application in the future.

Key words: ivermectin microemulsion injection; ivermectin; high performance liquid chromatography
