▎ 摘　　要

A nanocomposite composed of gold nanoparticle (Au)and three-dimensional graphene (3DGR) was electrodeposited on the surface of carbon ionic liquid electrode (CILE), which exhibited synergistic effects with improved electrochemical performance. Voltammetric behaviors of luteolin on Au/3DGR/CILE were evaluated with the electrochemical parameters calculated. At the selected conditions differential pulse voltammetric responses had good linear relationship with luteolin concentration from 5.0x10(-8) to 5.0x10(-5) mol L-1 and the detection limit was 7.59x10(-9) mol L-1. The Duyiwei soft capsules sample was successfully detected by the proposed method.
