咽喉清袋泡剂质量标准的研究
Military Medical Journal of South China(2017)
Abstract
目的 建立咽喉清袋泡剂的质量标准.方法 采用薄层色谱法(thin layer chromatography,TLC)对金银花、麦冬进行定性鉴别;采用高效液相色谱法测定咽喉清袋泡剂中君药金银花的有效成分绿原酸的含量,色谱柱:AgilentZORBAX SB-C18 (4.6 mmI.D.×150 mm Coi,S/N:USCL050569),流动相为甲醇-0.1%磷酸溶液(18∶82),检测波长:327nm,流速:1.0 ml/min.结果 薄层鉴别专属性强,分离效果好.绿原酸进样量8.52~106.55 μg/ml,与色谱峰面积呈现良好的线性关系(r=0.9999,n=5),平均回收率为99.9%[相对标准偏差(relative standard deviation,RSD)为1.56%,n=9].结论 建立的标准简便可行、结果准确、专属性强,可用于咽喉清袋泡剂的质量控制.
