摘要: 以核磁共振技术测定克拉霉素胶囊的含量为例,建立了核磁共振测定药物制剂含量的分析方法. 结果得到克拉霉素在1.03~24.72 mg/mL范围内具有良好线性关系,回归方程为: y=0.025 1X-0.026, r=0.999 2;平均回收率为98.7%(n=9). 测定结果的误差小于0.2%. 本方法具有灵敏度高、方法简单、重现性好的优点,可作为克拉霉素胶囊剂以及其他药物制剂的含量测定方法. 

Abstract: An NMR-based method for determining clarithromycin content in the capsules of the drug was developed. The linear range of the method was found to be 1.03~24.72 mg/mL. The regression equation derived was y=0.025 1X-0.026 (r=0.999 2). The average recovery rate was shown to be 98.7% (n=9), and the error was less than 0.2%. The results of this study showed that the NMR-based method for analyzing clarithromycin content has high sensitivity and good repeatability, and is easy to use.

Key words: NMR, internal standard, clarithromycin, quantification
