Abstract

[automatically translated] The kind oregano is so widespread in the Mediterranean basin, with various species present in Sicily. The ski nebroideo, which covers about 200,000 hectares, is characterized mainly by the presence of Origanum heracleoticum, it spreads ecologically very different to one another. In this study, thirty-six accessions of O. heracleoticum were taken from different wild populations of nebroideo area. The collected samples were transplanted in a field catalog specially made in Nebrodi Mountains territory, and regularly biomorfologici numerous characters were measured. Upon reaching the stage of full flowering it proceeded to the collection of samples of plant material, on which the gas chromatographic analyzes were carried out. The data obtained were subjected to cluster analysis and principal component analysis, allowing the distribution of accessions collected in 3 subgroups, discriminated according to some aspects of the habitus vegetative and flowering. The chemical analysis showed the presence of 4 characterizing compounds: p-cymene, γ-terpinene, cis-sabinene and thymol; the prevalence of the latter made it possible to attribute the studied accessions to type "thymol".
