In this study, we propose an electroanalytical method to quantify simultaneously luteolin and rutin, two flavonoids which are present in a pharmaceutical formulation. The methodology is based on square wave voltammetry at glassy carbon electrodes modified with multiwalled carbon nanotubes dispersed in polyethylenimine. Both flavonoids show quasi-reversible surface redox couples in 10% ethanol+1molL...
