摘要
目的建立测定藏药肺热普清散中乌头碱含量的高效液相色谱法。方法色谱柱为Phenomenex ODS柱(250 mm×4.6 mm,5μm),流动相为0.05 mol/L醋酸铵-乙腈(梯度洗脱),流速为1.0 mL/min,检测波长为235 nm,柱温为35℃,进样量为10μL。结果乌头碱进样量在0.046~1.440μg范围内与峰面积线性关系良好(r=0.999 6,n=6),检测限为1.2μg/mL;精密度、稳定性、重复性试验的RSD均小于2.0%(n=6),平均加样回收率为99.32%,RSD为0.41%(n=6)。结论所建立的方法稳定可靠,重复性好,可用于测定肺热普清散中乌头碱的含量。
Objective To establish a high-performance liquid chromatography(HPLC) method for the determination of aconitine in Feire Puqing Powder.Methods The chromatographic column was Phenomenex ODS column(250 mm x 4.6 mm,5 μm),the mobile phase was 0.05 mol/L ammonium acetate-acetonitrile(gradient elution),the flow rate was 1.0 mL/min,the detection wavelength was 235 nm,the column temperature was 35℃,and the injection volume was 10 μL.Results The linear range of aconitine was 0.046-1.440 μg(r=0.999 6,n=6),and the limit of detection(LOD) was 1.2 μg/mL.The RSDs of precision,stability and repeatability tests were less than 2.0%(n=6),and the average recovery of aconitine was 99.32% with an RSD of 0.41%(n=6).Conclusion The method is stable,reliable and reproducible,which can used for the content determination of aconitine in Feire Puqing Powder.
