摘要

目的:建立高效液相色谱法同时测定糙枝金丝桃药材中绿原酸、芦丁、金丝桃苷、槲皮素、山奈酚的分析方法。方法:用Sunfire C18(4.6 mm×250 mm,5μm)色谱柱分离;乙腈-0.1%磷酸进行梯度洗脱;流速1.0 mL.min-1;检测波长360 nm。结果:绿原酸、芦丁、金丝桃苷、槲皮素、山奈酚分别在0.01~0.61μg(r=0.999 6),0.10~2.02μg(r=0.999 7),0.10~1.01μg(r=0.999 9),0.10~1.24μg(r=0.999 7),0.005 7~0.17μg(r=0.999 7)线性关系良好;平均加样回收率分别为98.87%(RSD...
