目的 :为提高维C银翘颗粒的质量标准 ,建立样品中维生素C的含量测定方法。方法 :用经典方法—碘量法。结果 :与经典方法相比较 ,由于减半取样 ,缩短了滤过时间 ,使本法更加合理、迅速、结果准确。平均回收率为 97 82 6 3% ,相对标准差RSD =1 2 %。结论 :应用于维C银翘颗粒测定维生素C含量 。
Objective:To raise the quality standard of Wei C Yinqiao Grannules and establish a method for determination of vitamine C in sample.Methods:The content of Vit C were determined by the classical methods iodimetry.Results:Compared with classical methods,this method was more reasonable,rapid and accurate,because of shortening the filter time by reducing half of the number of sample.The average recovery was 97 8263% and RSD=1 2%.Conclusion:The method is used to determine the content of vitamine C in Wei C Yinqiao Granules and can control the quality of the products effectively.
