漆黄素检测方式:

 

漆黄素(fisetin)检测方法

 

一、色谱条件

色谱柱:Inertsil ODS-3 4.6×150mm  5μm

流动相:乙腈∶水∶磷酸(23∶77∶0.1,V/V)

检测波长:368nm

灵敏度:0.01AUFS

流速:1mL/min

进样量:10μL

柱温:25℃

 

二、溶液制备

  • 对照品溶液制备  精密称取漆黄素对照品约3mg于25mL容量瓶中,用甲醇溶解定容。
  • 样品溶液制备  精密称取样品(含量约10%)50mg于50mL容量瓶中,加约30mL甲醇,超声振荡溶解30min,冷却至室温,用甲醇定容,以0.45μm微孔滤膜过滤,即得。

三、样品测定

    在上述色谱条件下,待仪器稳定,基线平稳后,进样测定,漆黄素保留时间约为20min,含量按外标法计算。
