Abstract

An electrochemical method for the determination of capsaicin was established using an unmodified screen-printed electrode. The effects of ethanol ratio, electrolyte solution variety, pH value and KCl concentration on the determination of capsaicin by cyclic voltammetry using the screen-printed electrode were studied. The feasibility of the method was tested by stability, precision, detection limit and recovery. Results showed that the optimal parameters for the determination of capsaicin by using this unmodified screen-printed electrode were as follows: 10% ethanol, pH 1 and 80 mmol/L KCl, and Britton-Robison, CH3COOH—CH3COONa and NaH2PO4—Na2HPO4 electrolyte solutions were all suitable for the determination of capsaicin. Linear calibration curve for capsaicin in the range of 0.80~107.72 μmol/L was obtained with a detection limit of 0.13 μmol/L. In addition, the method was of good stability, precision and recovery, which was consistent with the determination of capsaicin by HPLC. Therefore, this method could be used for the rapid determination of capsaicin.
