Determination of active ingredients in mutouhui by capillary electrophoresis with electrochemical detection.


Capillary zone electrophoresis with electrochemical detection has been used for the separation and determination of scopoletin, hyperin, chlorogenic acid, and quercetin in Mutouhui. The effects of several important factors, including running buffer acidity, separation voltage, and working potential, were evaluated to achieve the optimum conditions. The… (More)
