The electrodeposition of a film of reduced graphene oxide (ERGO) with well-dispersed on a glassy carbon electrode (GCE) was achieved using cyclic voltammetry (CV) in a graphene oxide (GO) colloidal solution. Using square wave adsorptive stripping voltammetry (SWASV), the ERGO film was applied for the first time, in developing a high-sensitive electrochemical sensor for detection of taxifolin. Compared with bare GCE, the resulting electrodes (ERGO/GCE) exhibited excellent response toward the oxidation of taxifolin by significantly enhancing the oxidation peak currents and the decreased peak-to-peak separation. Under selected conditions, the reduction peak currents had linear relationship with taxifolin concentration in the range of 5.0 x 10(-8) - 1.5 x 10(-6) mol L-1, with detection limit of 4.0 x 10(-9) mol L-1. Besides, the method was successfully applied to the quantitative determination of taxifolin in the Prince's-feather fruit with satisfactory results.
