HPLC法同时测定地米樟酚乳膏中醋酸地塞米松、樟脑和苯酚的含量
目的 建立以HPLC法同时测定地米樟酚乳膏中醋酸地塞米松、樟脑和苯酚含量的方法。方法 色谱柱为SHIADZU-GL Inertsil? ODS-3 RP C18,流动相为甲醇-水(60:40),检测波长为285 nm,流速为1.0 ml/min,柱温为40℃,外标法定量。结果 醋酸地塞米松、樟脑和苯酚的线性范围分别为4.024~40.24、101.7~2 033和10.38~425.2 μg/ml,相关系数r 〉0.999 5;三者的平均回收率分别为101.2%(RSD为0.56%)、99.89%(RSD为0.72%)、100.2%(RSD为0.97%);重复性试验中RSD均小于1.5%。结论...

The flow rate was 1.0 ml/min. The detection wave length was 285 nm and the column temperature was 40℃.Results Dexamethasone acetate,camphor and phenol showed good linearity (r〉0.999 5, n=7) within the concentration range of 4.024-40.24,101.7-2 033 and 10.38-425.2 μg/ml,respectively. The average recovery of dexamethasone acetate, camphor and phenol was 101.2%(RSD was 0.56%),99.89%(RSD was 0.72%),100.2%(RSD was 0.97%),respectively. Moreover, the RSDs were less than 1.5% in the repeated tests. Conclusion The method was simple, quick and accurate. It is s |
