目的:建立高效液相色谱法测定"网脱Ⅰ号"口服液中阿魏酸的含量。方法:采用Diamonsil C18柱(150 mm×4.6 mm,5μm),以乙腈-1%冰醋酸(17∶83)为流动相,流速为1.0 mL·min-1,检测波长为300 nm。结果:阿魏酸在10~50μg·mL-1范围内呈良好的线性关系(r=0.999 36);平均回收率为100.86%,RSD=1.92%。结论:所建方法简便快速、准确、重复性好,可用于"网脱Ⅰ号"口服液的质量控制。
Objective:To establish an HPLC method for determining the content of ferulic acid in "NoⅠDetachment of Retina" oral solution.Methods:A Diamonsil C18 column(150 mm×4.6 mm,5 μm) was used for separation.The mobile phase consisted of acetonitrile-1% glacial acetic acid(17:83) at the flow rate of 1 mL·min-1,and the detection wavelength was set at 300 nm.Results:The linear range of ferulic acid was 10-50 μg·mL-1(r=0.999 36),with average recovery rate of 100.86%,and RSD of 1.92%.Conclusion:The method was simple,fast,accurate and reproducible,and it can be used for the quality control of "NoⅠDetachment of Retina" oral solution.
