摘要
目的 :建立双氯芬酸钠凝胶剂的含量测定方法。方法 :采用紫外分光光度法于 2 76 nm波长处测定其吸收度并计算含量。结果 :线性范围在 5~ 30 μg/ ml,回归方程 :A=0 .0 3185 c- 0 .0 132 3;r=0 .9999(n=6 ) ,平均回收率为 10 0 .4 2 % ,RSD=0 .88%。结论 :方法简便 ,准确 。
OBJECTIVE:To establish a method for the determination of diclofenac sodium gel.METHOD:An ultraviolet spectrometric method has been adopted.The absorbance of the preparation was measured at 276nm,and the content of diclofenac sodium was calculated.RESULTS:The linear range was 5~30 μg/ml,the regresion equation:A=0.03185c-0.01323;r=0.9999(n=6).The average recovery from the sample was 100.42%,RSD=0.88%.CONCLUSION:The method is simple,relible and suitable for the assay of the preparation.
