HPLC法测定盐酸消旋山莨菪碱注射液含量
Journal of Huaihai Medicine(2010)
Abstract
目的建立高效液相色谱法测定盐酸消旋山莨菪碱注射液的含量。方法C18色谱柱(shim-pack 4.6×150mm,5μm);流动相:0.02%三乙胺-甲醇(50:50);检测波长:220nm。结果消旋山莨菪碱浓度在0.05mg/ml~0.7mg/ml范围内与峰面积有良好的线性关系,回归方程为A=3.0911×104C+2.0033×104,平均回收率为95.88%(n=9),r=0.9999,RSD=0.9%。结论HPLC简便、可靠、重现性好,可用于该品的含量测定。
