The poly SudanⅢ modified electrode was characterized by electrochemical impedance spectroscopy(EIS)and cyclic voltammetry (CV), while the electrochemical behavior of paeonol was studied by cyclic voltammetry (CV). The result shows that the poly Sudan Ⅲ modified electrode exhibits excellent electrocatalytic effect on the oxidation of paeonol. The peak currents of differential pulse voltammetry are linear to the paeonol concentrations over the range of 3.0*10-7 ~ 2.2*10-5 mol·L-1. The detection limit has been estimated to be 5.0*10-8 mol·L-1. This method can be used for determination of paeonol content in real sample with satisfactory results.
