摘要
目的:建立香荠清膏质量控制方法。方法:采用薄层色谱法对香蕉皮、荠菜进行鉴别,并用高效液相色谱法对清膏中葛根素进行含量测定。结果:薄层图谱斑点清晰,专属性强。葛根素在0.7704～19.2600mg/L浓度范围内有良好的线性关系(r=0.9997),平均加样回收率为100.5%(RSD=1.7%,n=6)。结论:该法简便、快速、重复性好,可用于香荠清膏的质量控制。
Objective： To establish a method for controlling the quality of Xiang-Ji plaster. Methods： Banana peel and shepherdspurse herb were identified by TLC and the content of puerarin in plaster was determined by HPLC. Results： The TLC image was clear and the method had a good specificity. The calibration curve was linear in the range of 0.770 4-19.260 0 pg/mL for puerarln （r = 0.999 7）. The mean recovery was 100.5% （RSD = 1.7%, n = 6）. Conclusion： The method was applicable in controlling the quality of Xiang-Ji plaster.
