Variability of essential oils of Satureja montana L. and Satureja kitaibelii Wierzb. ex Heuff. from the central part of the Balkan peninsula

The results of the essential oil composition confirm that there are differences between populations within the same subspecies (Satureja montana ssp. montana, between the subspecies (Satureja montana ssp. montana and Satureja montana ssp. pisidica) and the species (Satureja montana and S. kitabelii). The essential oil composition of S. montana ssp. montana is more related to the Satureja montana ssp. pisidica than S. kitaibelii which separates as a whole species.

Essential oil and its systematic significance in species of Micromeria Bentham from Serbia & Montenegro

The composition and quantity of the essential oil of Micromeria allowed us to clearly distinguish between sections Pseudomelissa and Eumicromeria. According to our results the species of section Pseudomelissa (M. thymifolia, M. albanica, M. dalmatica and M. pulegium) contained a large quantity of oil (>0.5%) dominated by oxygenated monoterpenes of the menthane type, while the species of section Eumicromeria (M. croatica, M. juliana, M. cristata and M. parviflora) had a small quantity of essential oil (<0.5%) dominated by various terpene compounds. 0.5% of essential oil is defined like boundary value on the basis of the lowest quantity of essential oil measured in populations of species of section Pseudomelissa.

Chaerophyllum coloratum L.: Essential Oils of Ripe Fruits and Umbels

ABSTRACT Essential oils of ripe fruits and umbels of Chaerophyllum coloraturn L. (Apiaceae) were found by GC and GC/MS to contain very high percentage of (E)-Pfarnesene (79.21% and 68.40% respectively).

A comparative study on the needle volatile constituents of three Abies species grown in South Balkans.

Abstract The phylogenetic relationships of the three Abiesspecies grown in Balkan Peninsula were investigated through their volatile secondary metabolites. The leaf oil of a statistically representative sample of sympatric Abies alba, A. cephalonica and A. borisii-regis trees was obtained and analyzed by means of GC and GC/MS. Forty components were identified and quantified on the basis of their retention indices, their mass spectra characteristics and relative peak areas. The majority of the investigated oils were found to consist of monoterpenes. The major constituents were the same in all studied species but their content varied significantly, thus allowing the assignment of characteristic chemical profiles based on their contribution rank. The variation of the oil constituents and their possible taxonomic significance is discussed.

Chemical composition of the essential oil of Thymus bracteosus vis. ex Bentham (Lamiaceae)

Abstract The oil composition of Thymus bracteosus Vis. ex Bentham, collected from Montenegro, was analyzed by GC and GC/MS. The oil yield was 0.15%. Twenty-seven components were identifed. Terpene hydrocarbons were dominant in the oil (68.5%). The main constituents of the oil were germacrene D (15.5%), β-caryophyllene (14.6%), p-cymene (10.2%) and α-pinene (7.2%).

Essential Oil Composition of Some Populations of Mentha arvensis L. in Serbia and Montenegro

Abstract The essential oil of six population of Mentha arvensis L. in Serbia and Montenegro were studied. Two populations of subsp. agrestis(Sole) Briq., were found to produce oil rich in pulegone (49%-28%). Three of the studied populations proposed as subsp. austriaca,were unusual in that a major compound was menthofuran (11.5%-299%) which is diagnostic of M. aquaticaand its hybrids, whereas the third population produced oil deficient in monoterpenes. The three chemical races are distinct from those described previously for the two subspecies in F. urope, and the occurrence of a menthofuran-rich oil indicates that these population may be rather considered as natural hybrids with M. aquatica and co-located in the M. x verticilatagroup.

Leaf and stem anatomy of Micromeria species from the Central part of the Balkan Peninsula

Abstract The anatomical structure of the leaf and stem of nine Micromeria species from the Balkan Peninsula was investigated with the aim to establish the adaptive characteristics and traits that could be useful in the identification of species and subgeneric classification. The species included in the anatomical analysis were:Micromeria albanica (Griseb. ex K. Malý) Šilić, M.thymifolia (Scop.) Fritch , M. pulegium (Rochel) Bentham, M. dalmatica Bentham of section Pseudomelissa and M. cristata (Hampe) Griseb., M. kosaninii Šilić, M. juliana (L.) Bentham ex Reichenb., M. croatica (Pers.) Schott M. parviflora (Vis.) Reichenb. of section Micromeria. Variability of 17 quantitative characters of the leaf (thickness, height of adaxial and abaxial epidermis, thickness of the palisade and spongy tissue) and stem (radius, cortex thickness, thickness of the vascular cylinder, phloem, xylem, pith radius) was examined. Multivariate analysis of variance (ANOVA), principal component analysis (PCA), canonical discriminant analysis (CDA) and UPGMA clustering method based on Mahalanobis’ distances were used to determine the variability structure and level of importance of the anatomical differentiation of the investigated taxa. Qualitative characters were also included in the consideration of the anatomical variability, such as leaf shape, leaf margin, position of sclerenchyma fibers in the leaf and stem. The results showed that investigated Micromeria species posses a xeromorphic general structure plan, but each species has achieved distinctive adaptations according to its specific genetic potential. The results have shown a clear difference between the species belonging to the different sections of genus Micromeria, so they have a potential diagnostic and systematic value.
