橙皮甙、柚皮甙、橙皮素和柚皮甙元4种物质的毛细管电泳分离及测定

Separation and determination of hesperidin,Naringin, Hesperetin and Naringenin by capillary electrophoresis

通过优化缓冲溶液pH和浓度、分离电压和进样时间等条件,建立了橙皮甙、柚皮甙、橙皮素和柚皮甙元4种物质的毛细管电泳分离分析方法.在优化的条件下10 min内实现了4种物质的毛细管电泳分离.橙皮甙、柚皮甙、橙皮素和柚皮甙元4种物质分别在0.03～0.80、0.03～0.85,0.02～0.60和0.02～0.65mg/mL浓度范围内和峰电流成线性关系,检出限分别为0.007、0.006、0.004和0.005 mg/mL.方法用于分析模拟样品得到满意的结果,有望用于实际样品分析.
