热病预防合剂质量标准研究

Studies on Quality Standard of Prevent Rebin Mixture

目的 建立热病预防合剂的质量标准。方法 采用TLC法对本品中黄芪、黄芩、金银花、板蓝根及贯众进行了定性鉴别 ,并采用双波长薄层扫描法测定了黄芪甲苷的含量。结果 黄芪甲苷在 0 .4～ 2 μg范围内 ,点样量与峰面积呈良好的线性关系 ,平均回收率为 99.98% ,RSD为 2 .18%。结论 方法简单 ,专属性强 ,重现性好 ,可作为该产品的质量控制标准。

Aim To establish the quality standard of Prevent Rebin Mixture.Methods Radix Astragall,Radix Scutellariae,Flos Lonicerae,Radix Isatidis and Dryopteris Crassirhizomae in the mixture were identified by thin-layer chromatography and AstragalosideI was determined by TLC-scanner.Results Methods of TLC are simple and reliable,a good linearity was shown at the concentration of 0.4～2μg of Astragaloside I,the average recovery was 99.98% and the RSD was 2.18%.Conclusion These methods are simple and specific with a good repeatability and can be used for the quality control of preparation.
