摘　　要：目的：建立荡石片质量控制方法.方法：采用TLC法对牛膝进行定性鉴别;采用沉淀滴定法对硫酸钠进行定量分析.结果：薄层色谱斑点清晰,阴性对照无干扰;硫酸钠在0.1000～2.000g范围内良好线性关系,平均加样回收率为99.2％,RSD=0.90％（n=6）.结论：所建立的方法能准确可靠地进行定性、定量检测,重现性良好,可作为荡石片的质量控制方法.Objective： To establish qualitative and quantitative control methods for Dangshi Tablets. Methods： TLC was performed to i- dentify Achyranthis Bidentatae Rasix in Dangshi Tablets. Precipitation titration was used to determine the contents of Na2SO4. Results： The spots on TLC plates were clear without interference. The linear range of Na2 SO4 was within 0. 1000 - 2.000g, and the average re- covery was 99.2% , RSD = 0.90% （ n = 6）. Conclusion： The methods are simple, reliable, accurate, reproducible, arid suitable for the quality control of Dangshi Tablets.
