“…Another study have demonstrated the genotypical determination of the chemical diversity of Albanian O. vulgare populations . In contrast, a study on the Turkish Origanum onites indicated that there is no relationship between genetic structure of the species and EO composition . Other researchers propose that some changes in the EO composition of the Italian O. vulgare are due to both genotype and habitat influences.…”

The present study aimed to evaluate the influence of environmental factors on essential oils (EOs) composition of Origanum compactum populations sampled all over the distribution area of the species in Morocco, and to determine the extent of the chemical profiles throughout the geographical distribution of the species. The chemical compositions were submitted to canonical correlation analysis and canonical discriminant analysis that indicated a significant relationship between oil components and some environmental factors. According to their chemical composition and edapho-climatic characteristics, two major groups of populations were differentiated. The first group was composed of samples growing in regions with humid climate, clayey, sandy, and alkaline soils. These samples showed high thymol, α-terpineol, linalool, and carvacryl methyl oxide content. The second group consisted of plants belonging to semi-arid climate, and growing at high altitudes and silty soils. These samples were characterized by high carvacrol, α-thujene, α-terpinene, and myrcene content. However, populations exposed to sub-humid climate, appeared less homogeneous and belong mainly either to the first or second group. A significant correlation between some edaphic factors (pH, K O content, soil texture) and the EOs yield of O. compactum plants was evidenced. In spite of the correlation obtained for the oil composition with edapho-climatic factors and the variance explained by the environmental data set, the observed EO diversity might be also genetically determined.

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. Albania is 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.

“…The Mantel test showed that Nei 's genetic distances and the Euclidean distances of the fatty acids profile among populations did not correlate significantly ( r = −0.024, P = 0.087). The lack of correlation between the genetic data and the Euclidean distances of the essential oil was also shown in Oreganum onites L . Similarly, in Ocimum basilicum , the composition of the essential oil and the molecular data obtained by RAPD and AFLP were also not significantly correlated.…”

Jatropha curcas L. (Euphorbiaceae) is a shrub native to Mexico and Central America, which produces seeds with a high oil content that can be converted to biodiesel. The genetic diversity of this plant has been widely studied, but it is not known whether the diversity of the seed oil chemical composition correlates with neutral genetic diversity. The total seed oil content, the diversity of profiles of fatty acids and phorbol esters were quantified, also, the genetic diversity obtained from simple sequence repeats was analyzed in native populations of J. curcas in Mexico. Using the fatty acids profiles, a discriminant analysis recognized three groups of individuals according to geographical origin. Bayesian assignment analysis revealed two genetic groups, while the genetic structure of the populations could not be explained by isolation-by-distance. Genetic and fatty acid profile data were not correlated based on Mantel test. Also, phorbol ester content and genetic diversity were not associated. Multiple linear regression analysis showed that total oil content was associated with altitude and seasonality of temperature. The content of unsaturated fatty acids was associated with altitude. Therefore, the cultivation planning of J. curcas should take into account chemical variation related to environmental factors.
