## Abstract A capillary electrophoresis method was developed for the separation and determination of adenosine, rutin, and quercetin in __Flos Carthami__. The CE separation was achieved using 50 mmol L^โ1^ sodium tetraborate solution (pH 9.7) containing 18% methanol as the running buffer, with an a
Five flavonoids (catechin, hyperoside, quercitrin, quercetin, and rutin) were separated and determined by capillary electrophoresis with electrochemical detection. Effects of several important factors, such as the pH and concentration of running buffer, separation voltage, injection time, and detect
