ABSTRACT:
In
this study are presented the results of studies for oregano in 16 locations
(sites) of Albania for the content of the quantity of oils and their fractions.Albaniais the one of the important diversity centers for Oregano because of their
adaptation to diverse agro ecological conditions as a result of natural
selection. The design of the experiment was based on split plot methods. From
the total samples collected, were selected 16 mostly widespread samples of
natural populations of origano (Origanum
vulgare L. sp. vulgare and sp. hirtum). Essential oil isolation from oregano was performed by
hydro distillation. Identification of the components was made by comparing mass
spectra of components in essential oils with those from Nist, Wiley and Adams
mass spectra libraries. The results show that the total oil content varies from
3.45% to 0.1%. The populations of Oregano in the part of southern Albania have
a higher amount of etheric oil compared with those of the North part. The
higher content of carvacrol in 55.63%, of the samples was determined in sites
of the southern part of Albania, while in the other two investigated area
central and north part it was 55.63% and 48.49% respectively. The same indicators
were realised also for content of linalool and thymol, while North area has
sites with high content of caryophyllen-oxide and β-pinen 3. But, in all sites, the oils of thymol and carvacrolit
were dominant.
