A high-performance capillary electrophoresis with amperometry detection method(CE-AD)has been developed for the analysis of flavonoids and anthraquinones(emodin,kaempferol,apigenin,luteolin and rhein)in chrysanthemum.Under optimum conditions,these five analytes were base-line separated within 17 min using a borate-phosphate running buffer(1.5 × 10-2mol/L borate-3 × 10-2 mol/L phosphate running buffer,pH 9.0)at a working potential of+0.90 V(vs.SCE)and a separation voltage of 19 kV.The linear relationship between concentration and current response was obtained with detection limits(S/N = 3)ranging from 1.0 × 10-7 to 2.1 × 10-7 g/mL for all analytes.This proposed method was successfully used in the analysis of four kinds of chrysanthemum with relatively simple extraction procedures,the assay results were satisfactory.
