| 摘 要： | 目的:研究、建立中药车前草药材的定性定量方法。方法:以大车前苷(plantamajoside)为专属性指标成分,以硅胶G为吸附剂,醋酸乙酯-甲醇-甲酸-水(18∶3∶1.5∶1)为展开剂,紫外光灯(365 nm)下检测,建立车前草药材的薄层色谱鉴别方法。用高效液相色谱法进行含量测定,艾杰尔Promocil C18色谱柱(4.6 mm×250 mm,5μm),流动相为乙腈-0.1%甲酸水(17∶83),流速1.0 mL.min-1,检测波长330 nm,柱温30℃。结果:车前草药材薄层色谱在紫外光灯(365 nm)下检识,大车前苷呈亮蓝色荧光斑点,斑点清晰,分离效果理想;高效液相色谱法含量测定大车前苷在0.049 9~11.966 4μg呈线性(r=0.999 9);加样回收率为100.6%,RSD 2.7%;测得11批车前草中大车前苷的含量在0.067%~1.80%。结论:通过对11批车前草中的大车前苷的定性和定量分析,证明所建立的薄层色谱鉴别和高效液相色谱法含量测定方法灵敏,准确可靠,重复性好,为车前草的品质评价和质量标准建立提供了科学依据。 |
