摘要
目的建立阿替洛尔片中阿替洛尔的含量测定方法。方法采用HPLC法,色谱柱为Dinamonsil-C18柱,以甲醇-水(550:470)1000mL,加庚烷磺酸钠960mg与无水醋酸钠82mg使溶解,加冰醋酸0.57mL为流动相;流速为1.0mL·min^-1;检测波长为276nm,柱温为28℃。结果阿替洛尔进样量在0.1800~1.8000μg呈良好线性关系;其回归方程为Y=0.0781X(r=0.9999);平均回收率为97.08%;RSD为1.33%(n=9)。结论本方法操作简单,准确,可用于测定阿替洛尔片的含量。
Objective To determine the contents of atenolol in atenolol tablets. Methods HPLC method was used . The separation was performed on a Dinamonsil-C18 and column, methanol-water (550 : 470) 1 000 mL. C7H15SO3 Na 960 mg and CH3COONa 82 mg were add HOAc 0.57 mL as the mobile phase; the flow rate was 1.0 mL · min^-1 ; the detection wavelength was 276 nm, and the column temperature was 28℃. Results Atenolol showed a good linearity in 0. 180 0-1. 800 0μg. Y= 0. 078 1 X (r=0. 999 9); the average recovery rate was 97.08%, and the RSD was 1.33% (n=9). Conclusion The method is simple, accurate, and it is suitable to determine the content of atenolol.
