Confronto chemiotipico tra accessioni spontanee e coltivate del genere Thymus raccolte sui monti Nebrodi (Sicilia N-E)

[automatically translated] Accessions of Thymus Thymus spinulosus longicaulis and were harvested in different wild populations in the area of the Nebrodi Mountains of different ecological contexts. The samples, collected in the spring and summer of 2007 and then placed in a catalog field, have been the subject of observations in respect to major bioagronomici parameters. At full bloom, and the samples in the field catalog that those remaining in the natural stations were subjected to analysis by gas chromatography, and we proceeded to make the comparison chemiotipico between the two groups. In both species, the most representative compounds have proved p-cymene, -terpinene, cis-sabinene hydrate and thymol, but the existence of a very large variability between individual accessions prevents a unique identification of chemotypes.
