In the study, a genetic pool was created with plant samples taken from the locations where the Thymbra spicata var. spicata L. plant, which is culturally and economically important, grows densely in the province of Hatay. Plants were propagated with cuttings taken from these single plants. 213 plants were collected from 68 different locations for the genetic pool. The leaves of the plants in this gene pool were examined in terms of the number of essential oil glands per unit area and the diameter of the essential oil glands. The number of glands per unit area in plant leaves showed a wide variation and ranged from 5.61 to 56.04 pieces/mm². The diameters of the oil glands varied between 75.40 - 112.86 µm and the average diameter was determined as 94.09 µm. In the study, it was determined that some plants with low essential oil ratios such as Z144 and Z158 also have low oil glands number and oil glands diameter. It would be appropriate to evaluate these values obtained as preliminary knowledge together with future ontogenetic variability studies.

Thymbra Spicata

In the study, it is aimed to create breeding lines of thyme (Thymbra spicata L.), which is important both culturally and economically, by selecting a single plant among the plants grown in different regions in Hatay. For this purpose, a genetic pool was created for Thymbra spicata L. plant in the plant samples taken from the locations where the plants are densely grown, and these plants were examined in terms of leaf characteristics, number of oil glands per unit area, oil gud size and essential oil components. Plants were propagated and preserved with cuttings taken from these single plants. In this study, which includes the pre-selection stage, 213 plants from 68 different locations were determined in the province of Hatay. The essential oil ratios of the plants varied between 0.70% and 3.90% and showed a wide variation. The rate of carvacrol, which is the main component of the essential oil of the thyme plant, was between 28.12% and 78.48%. Plants with code number Z14, Z3, Z25, Z38, Z77, Z104, Z35 and Z43 with an essential oil ratio of 3.5% and above and plants with code number Z167, Z165 and Z64 with a high carvacrol ratio were selected to be used in future breeding studies.

Plant samples of Lepidium campestre (L.) W. T. Aiton (pepperwort) were analyzed in detail by GC and GC-MS. The analysis of the autolysates obtained from inflorescences, stems, leaves, and underground parts and the essential oil obtained by hydrodistillation allowed the identification of a series of glucosinolate degradation products, mainly isothiocyanates and nitriles. Besides previously identified ones in this species, the analyses resulted in the identification of degradation metabolites identified in pepperwort for the first time, and suggested the presence of heptyl glucosinolate, 3- phenylpropyl glucosinolate, glucoiberverin, glucoiberin, sinalbin, glucoerucin, glucoberteroin, gluconasturtiin, glucolepigramin, glucolesquerellin, glucobrassicanapin, and glucotropaeolin in this species as the most likely glucosinolate precursors. The results showed the localized accumulation of glucoberteroin, glucoerucin, and glucolesquerellin in the roots, the plant organ most exposed to pathogens, whereas sinalbin and glucobrassicanapin were accumulated in the reproductive organs and the organs most exposed to herbivores, i.e. in the aerial parts of the plant.

Air-dried aerial parts of wild Cladanthus mixtus were collected from two different regions of Morocco, Bouznika and Oujda, during 2011 and 2012. Forty individual plant samples were hydrodistilled using a Clevenger apparatus and the obtained essential oils were analyzed by GC and GC/MS. The yield obtained varies greatly with a range of 0.3 to 0.8%. The chemical composition of C. mixtus oils changes from one region to another. A total of 53 constituents were identified. To the best of our knowledge, two chemotypes were defined for the first time for this species in the regions studied. 2-Methyl-2- trans-butenyl methacrylate (32.8–35.2%) / ar-curcumene (13–14%) characterize the chemotypeof the C. mixtus plants from Bouznika, and trans-β-farnesene (35.5–50.3%) the chemotype from Oujda.

Abstract In this study, chitosan nanoparticles containing palmarosa essential oil (PEO-CNPs) were formed by ionotropic gelation, consisting of two parts: emulsion preparation followed by ionotropic gelation encapsulation with tripolyphosphate ions (TPP) as a crosslinker. The encapsulation method was optimized by varying three parameters, including chitosan concentration, initial oil loading in the emulsion and TPP concentration. The effects of these parameters on the encapsulation efficiency (EE) and loading capacity (LC) were analyzed. EE had an initial increase followed by a decrease in the range of three parameters. However, LC rose with varying initial oil content while it reduced with changing polymer and TPP concentration. The optimum experiment with the highest EE (10.0 g/L of chitosan, 5.0 g/L of TPP and 30.0 g/L PEO) was chosen to analyze the particle size using Dynamic Light Scanning method (DLS). With DLS measurement, the z-average diameter was 235.3 nm, and the particle size distribution was in the range of 100 – 500 nm.
