排石Ⅰ号颗粒剂质量标准讨论【摘要】 目的讨论排石 I 号颗粒的质量控制标准
方法采纳薄层色谱法对制剂中广金钱草、泽泻进行定性鉴别,采纳高效液相色谱法测定排石 I 号颗粒中的绿原酸的含量
结果金钱草、泽泻的薄层色谱鉴别专属性强;绿原酸进样量在 32~ 20 mg/ml 范围内呈良好的线性关系,r= 8
平均回收率为%,RSD =%
结论 该方法简便、灵敏、准确、重现性好,可作为排石 I号颗粒剂的质量控制标准

The content of chlorogenic acid was determined by HPLC
ResultsHerba Desmodii Styracifolii, Rhzoma Alismatis could be detected by TLC
A good linearity of chlorogenic acid was in the range of 32~ 20 mg/ml (r= 8) and the average recovery of Chlorogenic acid was % ,RSD was %
ConclusionThis method is simple,sensitive, accurate and with good reproducibility and can be used for the quality contr
