摘要:
目的 建立复方鼻用软膏中磺胺嘧啶的含量测定方法。方法 反相高效液相法,日本岛津Shim-pack VP-ODS柱(250L×4.6),国产C18保护柱,流动相:甲醇-水-冰醋酸(40:60:0.1),检测波长:270nm,流速0.6mL/min。结果 在11.26～123.82μg/mL范围内成线性关系,Y=144647X-41558,r=0.9999,平均回收率为100.2±1.5%,RSD为1.4%。结论 本方法简单、准确、快速,可用于本制剂磺胺嘧啶的快速定量分析。
Abstract:
Objective To establish a method for determination of the content of sulfadiazine in compound nasal ointment.Methods RP-HPLC was adopted with Shim-pack VP-ODS(250L×4.6) column as analytical column, methanol-water-aceti-cacid (40:60:0.1) as mobile phase.The detection wavelength was 270nm.The flow rate was 0.6mL/min. Results The linear ranges of sulfadiazine were 11.26-123.82μg/mL,Y = 144647X-41558,r =0.9999,the average recovery was (100.2±1.5)%,RSD was 1.4%(n=6).Conclusion The method is simple, rapid, accurate and suitable for the determination of sulfadiazine in compound nasal ointment.
