目的:建立金荞麦合剂的质量标准.方法:采用薄层色谱法鉴别金荞麦;采用高效液相色谱法测定金荞麦合剂中表儿茶素的含量,以十八烷基硅烷键合硅胶为填充剂;以乙腈-水[用磷酸调pH值至(3.00±0.02)](8∶92)为流动相;检测波长为280 nm.结果:薄层色谱法鉴别金荞麦操作简便、斑点清晰,分离度好,阴性无干扰;表儿茶素对照品线性范围为1.76 ~17.6 μg,r=0.997 5(n=6),平均样品加样回收率为99.35%,RSD为1.85%(n=6).结论:金荞麦合剂新的质量标准方法简便,重复性好,结果准确可用于金荞麦合剂的质量控制.“,”Objective:To establish the quality standard of Jinqiaomai Mixture/agopyrum dibotrys (D.Don) Hara.Method:Fagopyrum dibotrys (D.Don) Hara was identified by TLC;The mobile phase consisted of acetonitrile-water pH adjusted to (3.00 ± 0.02)] (8 ∶ 92) with high performance liquid chromatography.The detection wavelength was 280 nm,and the gold buckwheat mixture of epicatechin was determined in the content.Results:The linear range of epicatechin reference substance was 1.76-17.6 μg,r =0.997 5(n =6),and the average sample was collected by thin layer chromatography.The rate was 99.35% and the RSD was 1.85% (n =6).Conclusion:The new quality standard method of Jinqiaomai Mixture is simple and reproducible,and the result is accurate for the quality control.
