摘 要:目的 建立高效液相色谱(HPLC)法测定复方必消痰胶囊中磺胺甲基异嚷唑(SMZ)、甲氧卞啶(TMP)、盐酸溴己新的含量。方法 采用KF-C18(4.6mm×250mm,10μm)色谱柱;流动相:甲醇-水-0.01mol/L三乙胺甲醇溶液(95:5:1.5);流速:1.0ml/min;检测波长:249nm。结果 SMZ在4.56—22.8μg/ml、TMP在9.08。45.4μg/ml、盐酸溴已新在10.16—50.80μg/ml范围内呈起好线性关系(n均为5,r均为0.9999)。SMZ、TMP、盐酸溴己新的平均回收率分别为100.92%(n=9,RSD=2.03%)、99.06%(n=9,RSD=1.32%)、101.02%(n=9,RSD=0.62%)。结论 本法简便、快速、准确,适用于制剂的质量分析。Objective To establish a HPLC method for determination SMZ ,TMP and bromhexine hydrochloride in compound Bi Xiao Tan capsule. Methods KF - C18 (4.6mm × 250mm, 10μm) column was adopted; the mobile phase was methanol -water- 0.01mol/L triethylamine methanol (95: 5: 1.5 ) ; the flow rate was 1.0ml/min. The wavelength of detection was 249 nm. Results The linear range of SMZ, TMP and bromhexine hydrochloride were 4. 56 - 22. 8μg/ml, 9.08 45. 4μg/ml ,10.16 -50.80μ g/ml( n =5, r =0. 9999). The average recoveries of SMZ,TMP and bromhexine hydrochloride were 100.92% ( n =9 ,RSD =2.03% ) ,99.06% ( n =9 ,RSD = 1.32% ) , 101.02% ( n = 9, RSD = 0.62% ) respectively. Conclusion This method is simple, rapid and accurate for quantitative analysis of the preparation.
