Abstract

Orchidaceae is the largest family between monocots and represents one of the largest families of flowering plants with an estimated 12 to 35 000 species number. The taxonomic complexity of one of the genus of this family, Catasetum, has attracted much interest from growers and researchers in Orchidaceae, especially due to new taxa being discovered in the genus. Aiming to assist in improving the taxonomic classification of this genus, we propose to use chemotaxonomics analyzes using metabolomics and phylogenetic tools. For this, fingerprints on GC-MS and UHPLC-MS of the genus Catasetum, which will be correlated, using statistical multivariate analysis with the current taxonomic classification and phylogeny based on DNA will be obtained. Despite few described about the use of metabolomics tools for taxonomic studies and few reports on the chemical constituents of the genus Catasetum, the proposed approach can be a valuable tool in better understanding of the phylogenetic relationships and the taxonomic classification of the genus.
