Title Χωρική διαφοροποίηση της παραγωγής αιθέριων ελαίων από φυτά υψηλού εθνοφαρμακολογικού ενδιαφέροντος της οικογένειας Lamiaceae σε σχέση με περιβαλλοντικούς παράγοντες της νήσου Κρήτης

Abstract Lamiaceae family includes mainly herbaceous and shrubby plant species spread almost all over the world, mainly in open areas, including the Mediterranean Basin where the highest concentration of species appears. It is the most important family of aromatic plants in Greece, since the majority of its members produce essential oils, this family participates in all types of flora in different climatic conditions and contains many endemic species. In this study we used species of the Lamiaceae (Labiatae) family, specifically Salvia fruticosa, Origanum dictamnus (“Cretan dittany”) and Coridothymus capitatus. These three species were selected due to their high ethno-pharmacological interest as well as their use in the pharmaceutical and food industry. Despite the fact that several existing articles provide data of the above species’ essential oil components, and that the spatial variability of the essential oil composition is reported in some of them, an integrated approach based on spatial biological variability of the chemical profile of these species is still not accomplished; the importance of this is that the production of plant preparations used in the pharmaceutical and food industry can be standardized either in harvesting or cultivating plant material. It is known, that biological variability is affected by genetic, environmental and epigenetic factors, which also affect the spatial variability of the chemical profile and this fact emphasizes the necessity to study all the above factors simultaneously. In this study, which is part of a wider research project in progress, we examined the environmental impact to the chemical profile of the specific species, with the aim to study the spatial differentiation of their essential oil yields and their chemical profile as it is formulated by the impact of these factors. Although the results showed that essential oil yields of the specific species at Crete island were in agreement with up to date bibliography, due to the impact of environmental factors statistically significant spatial variation appears, which can be mapped using Generalized Linear Models. It can be useful for the raw material production design for the pharmaceutical and food industry in harvesting or cutivating plant material. The same conclusion has been appeared as far as secondary metabolites, which are included in the essential oil of the above species, are concerned. It is also concluded that the components of the essential oil composition of these plants harvested by cultivation appears to be consistent with the composition recorded in the adjacent native populations. All the above, the spatial variability of plant yields and the essential oil composition of the species under consideration, as well as the comparative assessment of cultivated plants with their indigenous populations are key tools for the raw material quality assurance and the quality control of herbal preparations produced by the pharmaceutical and food industry. .
