Resumo: The antioxidant capacity of essential oils of Mentha spicata L., Mentha x gentilis L., Mentha crispa L., Mentha piperita L. and Mentha x piperita L. was determined by using differential pulse voltammetry. This assay was based on the reduction in the limiting current value of the oxygen electroreduction, which was used to calculate the antioxidant capacity (K) of these species. The species M. x gentilis L. had the highest K value. Cyclic voltammetry experiments confirmed the interaction between the electrode surface and the active compounds present in the essential oils. A simple electrochemical method for determining the ability of active compounds to chelate Fe (II) is proposed.
