某院自制紫地糊剂质量标准的研究

Study on quality standard of Zi Di Paste

目的研究并制订该院自制紫地糊剂制剂的质量标准。方法对主要成分地榆和紫草作薄层鉴别;对主药炉甘石采用络合滴定法测定锌含量。结果薄层图谱斑点清晰,阴性对照无干扰。含量测定结果重现性好,RSD为0.103%。结论该质量控制方法简便可行,精密度高,重现性好,可用于紫地糊剂的质量控制。

Objective To establish the quality standard for Zi Di Paste. Methods Qualitative analysis of Sanguisorba Officinalis and Arnebia euchroma（Royle）Johnst were identified by TLC and the content of Zinc in Galamine was determined by complexometric titration. Results The spots in the TLC were clear and identified without the interference of negative control. The method for the determination was reproducible with RSD 0. 103%. Conclusion The methods are simple, feasible, accurate, and with good re- producibility and they can be used for the quality control of Zi Di Paste.
