摘要
目的 :建立易达拉封注射液中易达拉封的含量测定方法。方法 :采用反相高效液相色谱法在KromasilC18 色谱柱上 ,以0 1mol/L磷酸二氢钠缓冲液 -甲醇 (45∶55)为流动相 ,流速为1 0ml/min ,紫外检测波长为242nm ,外标法定量。结果 :易达拉封在1 24～24 8μg/ml之间线性关系良好 (r=0 9999) ,平均回收率为100 3 % (n=6) ,精密度为0 95%。结论 :本法简便、快速、准确 。
OBJECTIVE:To establish a method for determination of Edaravone cont en ts in injection METHODS:The Kromasil C18 column(4 6mm×200mm,5μm) was use d The mobile phase was consisted of 0 1mol/L NaH2PO4-methanol(45∶55) with detection at 242nm,flow rate was 1 0ml/min RESULTS:The linear range was 1 2 4μg/ml～24 8μg/ml(r=0 9 999),the mean recovery was 100 3% with RSD=0 9 5%(n=6) CONCLUSION:This method is simple,sensitive and accurate,and can b e used to control the quality of Edaravone injection
