摘要
目的建立复方脑清胶囊中盐酸水苏碱的含量测定方法。方法以乙酸乙酯-正丁醇-盐酸（1∶8∶3）为展开剂展开,采用薄层色谱扫描法测定。结果盐酸水苏碱在4.767~23.833μg的范围内具有良好线性关系,加样回收率为98.27%,RSD为1.51%。结论本实验建立的含量测定方法简便、可靠。
Objective To establish the method for determination of stachydrine hydrochloride in Compound Naoqing Capsules. Methods The separation of stachydrine hydrochloride was accomplished by development using ethylacetate-n-butanol-hydrochloric acid （1 ： 8 ： 3）, then determined by TLC. Results A good linearity was shown at the range of 4. 767 -23. 833/1g. The average recovery of stachydrine hydrochloride was 98.27%, and RSD = 1.51%. Conclusions The method is simple and reliable.
