鼻炎口服液检测方法的研究

Studies on Quality Control Standard of Biyan Oral Solution

建立鼻炎口服液的质量标准。采用TLC法鉴别辛夷、苍耳子、金银花,采用HPLC法测定辛夷中木兰脂素的含量。薄层色谱鉴别的3种供试品色谱中,在与对照品或对照药村色谱相应的位置上均能显示相同颜色的斑点;木兰脂素含量测定平均回收率为100.39%,RSD为0.73%。该方法可准确地进行定性、定量检测,有效控制制剂的质量。

A method for quality control of Biyan Oral Solution was esablished. Flos Magnoliae, Fructus Xanthii and Flos Lonicerae Japonicae were identified by TLC, and the content of Magnolin was determined by HPLC. The TLC indicated that threee identified herbs could show the same color pot with the control herbs or contrast in the same position. The average recovery of Magnolin was 100.39 %, RSD 0.73%. The methods are accurate and reliable, they can control the quality of this preparation effectively.
