RESUMEN

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 and also for trading as spices (dried pericarps or whole fruits). 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. This is a robust method to identify species in berries samples. 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.
