TITLE: | |
摘要: | 目的:建立测定当归芍药散中芍药苷含量的方法,以期为控制该制剂的质量提供参考。方法:采用高效液相色谱法。 色谱柱为Symmetry C18,流动相为乙腈-水(含0.1%磷酸)(14 ∶ 86,V/V),流速为 1.0 ml/min,检测波长为230 nm,柱温为20 ℃,进样量为20 μl。结果: 芍药苷检测质量浓度线性范围为10~80 μg/ml(r=0.999 3);精密度、稳定性、重复性试验的RSD<2%;加样回收率为 98.3%~104.9%(RSD=2.0%,n=9)。结论:该方法简便、准确、专属性强,可用于测定当归芍药散中芍药苷的含量。 |
ABSTRACT: | OBJECTIVE: To establish a method for the content determination of peoniflorin in Danggui shaoyao powder,and provide a reference for controlling the quality of the preparation. METHODS: HPLC was performed on the column of Symmetry C18 with mobile phase of acetonitrile-water(containing 0.1% phosphoric acid)(14 ∶ 86,V/V) at a flow rate of 1.0 ml/min, detection wavelength was 230 nm, column temperature was 20 ℃, and injection volume was 20 μl. RESULTS: The linear range of peoniflorin was 10-80 μg/ml(r=0.999 3); RSDs of precision, stability and reproducibility tests were lower than 2%; recovery was 98.3%-104.9%(RSD=2.0%,n=9). CONCLUSIONS: The method is simple, accurate and specific, and can be used for the content determination of peoniflorin in Danggui shaoyao powder. |
