Cover Picture. The authentication and traceability of spices is a major concern for industrials and consumers. We focused on species from Zanthoxylum genera which are used for many different applications by local populations. In this case, literature gives contradictory data about botanical names, and commercial labelling is often confusing. We studied commercial fruits pericarps extracts obtained by supercritical CO2 and analyzed them by GC/MS. The very complex volatile and semi volatile fractions composition of each extract is described. The barcoding method including molecular biology and phylogenetic analyses was also developed in order to check the commercial botanical identification of the raw material. We used one genetic marker to identify two Rutaceae clusters, including several species of Zanthoxylum genus. These results indicate that Fagara and Zanthoxylum groups could be considered as two different genera. Combination of chemical analysis and DNA analysis provides an original approach to increase chemical and botanical Zanthoxylum genus knowledge, as reported by Christine Perichet et al. in their full paper at https://doi.org/10.1002/cbdv.201800251.
