Simultaneous electrochemical determination of isoquercitrin (ISQ) and epigallocatechingallate (EGCG) at a carbon nanotube electrode is presented. The carbon nanotube electrode for ISQ and EGCG sensing has attractive properties in terms of well-defined current peaks, high sensitivity, and high reproducibility. Two well-distinguished anodic peaks +0.23 V and +0.38 V due to EGCG and ISQ are observed by cyclic voltammetry and those peaks are independent from each other. The linear ranges of ISQ and EGCG are 0.76–94 µM and 4.0–94 µM, respectively. The ISO and EGCG values of real sample determined by this method show good agreement with the actual ones.
