摘要
目的:建立高效液相色谱法测定一点红中槲皮苷含量的方法。方法:采用Kromasil RP-C18色谱柱(4.6 mm ×250 mm,5μm),以甲醇-0.1%磷酸溶液(55∶45)为流动相,流量1.0 mL· min-1,检测波长350 nm。结果:槲皮苷在11.40~114.0μg·mL-1范围内与峰面积成良好线性关系( r=0.9998),平均加样回收率为97.80%,其RSD为1.95%( n=6)。结论:该法简便,专属性好,可作为一点红的质量控制方法。
Objective:To establish an HPLC method for the determination of quercitrin in Herba Emiliae .Methods:The detection was performed on a Kromasil RP-C18column(250 mm ×4.6 mm,5μm)with the mobile phase of methanol -0.1%phosphoric acid (55∶45) at a flow rate of 1.0 mL· min-1 .The UV wavelength was set at 350 nm.Results:The calibration curve of quercitrin was linear in the rage of 11.40-114.0 μg· mL-1(r=0.999 8).The average recovery was 97.80%, with RSD of 1.95%(n=6).Conclusion:The HPLC method is simple , rapid and accurate which can be used for the quality control of Herba Emiliae .
