Abstract
[目的]建立消浊通淋颗粒中槲皮素和山奈素含量的测定方法,[方法]采用高效液相色谱法,色谱柱为岛津VP-ODS c (250.0mm x4.6 mm,5μm),流动相为甲醇-0.4%磷酸水溶液(48:52),流速为1.1 ml/min,检测波长为360 nm.[结果]槲皮素在0.075 2~0.2705μg范围内呈现良好线性关系,加样回收率为99.5%,RSD为0.30%(n=6);山奈素在0.113 0 ~0.406 8 μg范围内呈现良好线性关系,加样回收率为99.7%,RSD为0.34%(n=6).[结论]高效液相色谱法测定消浊通淋颗粒中槲皮素和山奈素的含量操作简单、准确、重复性好、精密度高,可以作为消浊通淋颗粒的质量控制方法.
