In this paper, the electrochemical behavior of rutin on a gold nanoparticles/ethylenediamine/multi-wall carbon nanotubes modified glassy carbon electrode (AuNPs/en/MWNTs/GCE) was investigated and the electrochemical parameters of rutin were calculated. Rutin effectively accumulated on the AuNPs/en/ MWNTs/GCE and caused a pair of redox peaks at around 487 mV and 432 mV (vs. SCE) in 0.1 M phosphate buffer solution (pH 3.5). Under optimized conditions, the anodic peak current was linear to the rutin concentration in the range of 4.8 108 M9.6 107 M. The regression equation was: ipa = 2.3728Crutin0.1782 (ipa: 105 A, Crutin: lM, r = 0.9973). The detection limit of 3.2 108 M was obtained. The proposed method was successfully used to the determination of rutin content in tablet samples with satisfactory results.
