A collection of nine Myrtus communis samples from different localities of Sicily was evaluated. Morphologicaltraits and production characteristics have been chosen as parameters to arrange the samples into homogeneousgroups and to identify the best biotypes for possible future agro-industrial exploitation. The plant material hasbeen subjected to taxonomic characterization from biometric and phytochemical perspectives. Myrtle berriesand leaves have been analyzed for their content in metabolites, applying a cascade extraction protocol for M.communis leaves and a single hydroalcoholic extraction for berries, whereas hydrodistillation procedures havebeen applied to obtain the essential oils from berries and leaves. The analyses of non-volatile components werecarried out by LC-UV-DAD-ESI-MS. All the extracts were characterized by the presence of numerous polyphenols,namely highly hydroxylated flavonols such as quercetin and myricetin; and ellagic acid detected in all samples.In addition, myrtle berries contained nine different anthocyanins, namely delphinidin, petunidin, cyanidin andmalvidin derivatives. The essential oils (EOs) were analyzed by a combination of GC-FID and GC/MS. A total of 33and 34 components were fully characterized with the predominance of α-pinene, myrtenyl acetate, linalool, 1,8-cineole and linalyl acetate. All phytochemical profiles were subjected to cluster analyses, which allowedsubdividing the myrtle samples in different chemical groups.
