%X Introduction - An innovative application of the voltammetry of microparticles methodology to characterize the phytochemical composition of extracts of different parts of Zanthoxylum chiloperone var. angustifolium Engl. is described. Objective - Characterize the phytochemical composition of extracts of different parts of plants by electrochemical methodologies. Methods - The voltammetry of microparticles methodology was applied to alcoholic extracts from leaves, seeds, fruits, roots and stem bark of Zanthoxylum chiloperone. Results - In contact with aqueous phosphate buffer, characteristic cathodic signals of its main natural products (canthin-6-one, 5-methoxycanthin-6-one and trans-avicennol) were recorded. The study of the voltammograns allows the estimation of the relative amounts of canthin-6-one, 5-methoxycanthin-6-one and trans-avicennol from the different parts of Zanthoxylum chiloperone. Conclusion - The voltammetric responses of alcoholic extracts from different parts of Zanthoxylum chiloperone var. angustifolium allows their phytochemical characterization without need of sample pretreatment thus illustrating the capabilities of the voltammetry of microparticles methodology to increase the tools applied to phytochemical analysis.
