摘要
目的:建立HPLC-CAD法测定硫酸卡那霉素注射液中卡那霉素和卡那霉素B含量的方法。方法:采用Boston Green ODS C18(250 mm×4.6 mm,5μm)色谱柱,以0.2 mol·L~(-1)三氟醋酸溶液-甲醇(95∶5)作为流动相,流速:1.0 ml·min~(-1),柱温:30℃,喷雾温度:55℃,喷雾压力:56.4 psi。结果:卡那霉素在0.385~38.500μg·ml~(-1)之间呈现良好的线性关系(r=0.999 9),检出限为0.075μg·ml~(-1),定量限为0.154μg·ml~(-1),回收率为100.97%(n=9)。卡那霉素B在0.374~37.400μg·ml~(-1)之间呈现良好的线性关系(r=1.000 0),检出限为0.075μg·ml~(-1),定量限为0.150μg·ml~(-1),回收率为100.44%(n=9)。结论:建立的HPLC-CAD测定卡那霉素和卡那霉素B含量的方法检出限低,操作简单准确,可以有效控制硫酸卡那霉素注射液的质量。
Objective: To establish an HPLC with charge aerosol detection( HPLC-CAD) method for the determination of kanamycin and kanamycin B in kanamycin sulfate injection. Methods: The samples were injected into a Boston Green ODS C18( 250 mm×4. 6 mm,5 μm) column. The mobile phase was composed of 0. 2 mol·L~(-1) trifluoroacetic acid aqueous solution-methanol( 95 ∶ 5),the flow rate was 1. 0 ml·min~(-1) and the column temperature was maintained at 30 ℃. The nebulization temperature for the CAD was maintained at 55℃ and the gas pressure was 56. 4 psi. Results: The linear range of kanamycin was 0. 385-38. 500 μg · ml~(-1)( r =0. 999 9),and the limit of detection was 0. 075μg·ml~(-1),the limit of quantitation was 0. 154 μg·ml~(-1),and the average recovery of the method was 100. 97%( n = 9). The linear range of kanamycin B was 0. 374-37. 400 μg·ml~(-1)( r=1. 000 0),and the limit of detection was 0. 075μg·ml~(-1),the limit of quantitation was 0. 150 μg·ml~(-1),and the average recovery of the method was 100. 44%( n= 9). Conclusion: The method for the determination of kanamycin and kanamycin B by HPLC-CAD is simple and accurate,the limit of detection is lower than HPLC-ELSD,and the quality of kanamycin sulfate injection can be effectively controlled.
