痰咳舒糖浆质量标准研究

Research of quality standard for Tankeshu syrup

目的制订痰咳舒糖浆的质量标准。方法采用薄层色谱法鉴别川贝母;采用紫外可见分光光度法（UV-VIS）测定贝母素乙的含量。结果薄层斑点清晰,阴性样品无干扰,贝母素乙在0.05-0.35 mg呈良好的线性关系,平均回收率为93.41%。RSD=2.23%。结论该方法准确、重复性好,可有效控制本制剂的质量。

Objective To establish the quality standard for Tankeshu syrup. Methods Thin-layer chromatography（UV-VIS） was applied for identification of dulbus fritillariae cirrhosae, and ultraviolet visible spectrophotometry for content of peiminine. Results Thin-layer had clear spots, without interference by negative samples. Peiminine showed fine linear relation in range of 0.05~0.35 mg, with the average recovery rate as 93.41% and RSD=2.23%. Conclusion This method has accuracy and good repeatability, and it can control the quality of Tankeshu syrup.
