摘 要:目的制定气管炎丸的质量标准。方法对方中麻黄、化橘红、党参进行薄层色谱(TLC)鉴别;采用高效液相色谱(HPLC)法测定柚皮苷的含量,色谱柱为C18柱(4.6mm×150mm,5μm);以甲醇-水(40:60)为流动相;检测波长为283nm,流速1mL·min^-1。结果薄层色谱鉴别中,供试品在与对照药材色谱相应的位置上,显示相同颜色的荧光斑点,斑点清晰,分离效果好,阴性未见干扰;HPLC法含量测定中,柚皮苷在0.1952~1.9520μg(r=0.9999,n=7)范围内呈良好的线性关系,平均加样回收率为100.82%(RSD为0.87%)。结论所建立方法简便、准确、专属性强、重复性好,能有效控制气管炎丸的质量。Objective To establish a quality control method of qiguanyan pill Methods TLC method was used to differentiate the ephedrine, codonopsis and citri grandis exocarpium. HPLC method was employed to determine naringin content. A C,s column (4.6 mm×150 mm,5 μm) was used with methanol and water (40 : 60) as a mobile phase. The flow rate was 1 mL · min^-1 , detection wavelength 283 nm. Results Samples and controls had the same color fluorescence spots at the same position. Spots were well isolated. Linear range was 0. 195 2-1. 952 0 μg (r= 0. 999 9, n = 7). Average recovery was 100.82% (RSD = 0. 87%, n = 6 ) . Conclusion The established method was sensitive, accurate, repeatable and specific for determination of naringin. It can be used for quality control of qiguanyan pill.
