【摘要】 目的:确定银翘伤风胶囊质量标准。方法:通过薄层鉴别方法(TLC)对处方中金银花、牛黄、芦根、甘草进行定性鉴别。运用高效液相色谱法(HPLC)对连翘中的连翘苷进行含量测定。结果:薄层色谱斑点清晰,阴性对照无干扰。含量测定连翘苷量在0.199-0.991μg之间有良好的线性关系,相关系数r=0.999 9。回收率为99.7%,RSD=0.48%(n=5)。结论:所建立的方法可靠,能准确地进行定性、定量检测,可用于该制剂的质量控制。更多还原

【Abstract】 Objective:To establish the quality standard for Yinqiaoshangfeng capsules.Methods:Flos Lonicerae、Calculus Bovis、Rhizoma Phragmitis and Radix Glycyrrhizae were identified by TLC.Forsythin was determined by an HPLC method.Results:TLC spots clear and specific.A good linear relationship between peak area and concentration of forsythin was found at the range of 0.199～0.991 μg with a correlation coefficient of r=(0.999 9).The average recovery of forsythin was 99.7% and RSD was 0.48%(n=5).Conclusion:The method is reliable,accurate and specific.It can be used for the quality control of Yinqiaoshangfeng Capsules.更多还原
