摘要
目的建立白柏颗粒质量标准。方法采用薄层色谱法对处方中的白术、党参、茯苓、黄芪进行定性鉴别;采用高效液相色谱法对样品中的甘草酸进行含量测定。结果薄层鉴别的分离度好,专属性强,阴性对照无干扰;含量测定甘草酸质量浓度（以甘草酸单铵盐计）在6~60μg/mL范围内与峰面积线性关系良好（r=0.999 9）,平均回收率为98.89%（n=6）,RSD为0.66%。结论所建立的方法准确、可靠、专属性强,可用于该制剂的质量控制。
Objective To establish the quality standards of Baibai Granules.M ethods The atractylodes macrocephala,codonopsis pilosula,poria cocos,astragalus membranaceus were indentified by TLC,and the content of glycyrrhizic acid was determined by HPLC.Results The characteristic identification by TLC was distinct and highly specific.Glycyrrhizic acid showed a good liner relationship at the range of 6-60μg/mL（r= 0.999 9）,and the average recovery rate was 98.89%with RSD of 0.66%（n = 6）.Conclusion The method is reliable,accurate and specific,which can be used for the quality control of the preparation.
