Microwave-assisted extraction followed by capillary electrophoresis-amperometric detection for the determination of antioxidant constituents in Folium Eriobotryae.

Abstract

A method based on capillary electrophoresis-amperometric detection has been developed for the determination of catechin, rutin, kaempferol, gentistic acid, and quercetin in Folium Eriobotryae with the aid of microwave-assisted solvent extraction. The effects of the acidity and the concentration of the running buffer, separation voltage, injection time… (More)
