Electrochemistry-based chemotaxonomy in plants using the voltammetry of microparticles methodologyElectronic supplementary information (ESI) available. See DOI: 10.1039/c5nj01233c

A methodology for characterizing vegetal taxonomic groups using microextraction-assisted voltammetry of microparticles is described. It is based on recording the voltammetric response of microparticulate films of polyphenolic compounds of leaf extracts using different organic solvents. As a result, characteristic voltammetric profiles, tentatively defining an electrochemolomic response, are obtained. Bivariant and multivariant chemometric evaluation of the voltammetric responses of such films allows characterizing vegetal families. Analysis of voltammetric responses for a set of species of the Rosales order suggests that electrochemical data can be correlated with phylogenetic trees. Characterization of vegetal taxa is achieved via characteristic voltammetric features displayed by leaf extracts.
