Cuticular Wax Variability of Abies alba, A.×borisii-regis and A. cephalonica from the Balkans: Chemophenetic and Ecological Aspects.

This is the first study on cuticular wax variability of Abies alba, A.×borisii-regis and A. cephalonica, using 18 native populations from the assumed hybrid zone in the Balkan Peninsula.

Essential Oils of Three Balkan Abies Species: Chemical Profiles, Antimicrobial Activity and Toxicity toward Artemia salina and Drosophila melanogaster.

This study focused on the essential oils (EOs) isolated from needles with twigs of three indigenous Balkan Abies species (A. alba, A. × borisii-regis and A.

Essential Oils of Six Achillea Species: Chemical Profiles, Antimicrobial Potential and Toxicity toward Crustaceans.

This is the first comparative study on antimicrobial activity of essential oils (EOs) of six Achillea species (A. crithmifolia, A. distans, A.

Pseudotsuga menziesii (Pinaceae): Volatile Profiles, Antimicrobial Activity and Toxicological Evaluation of Its Essential Oil.

The present article investigates the chemical composition of volatiles of essential oil (EO) and headspace (HS) fraction, as well as biological activities of EO obtained from needles with twigs of Pseudotsuga menziesii var. menziesii cultivated in Serbia. The major class of compounds was monoterpene hydrocarbons with α-terpinolene, sabinene and β-pinene (EO), and sabinene, α-terpinolene and β-pinene (HS) as the dominant volatiles.

Needle volatiles as chemophenetic markers in differentiation of natural populations of Abies alba, A. x borisii-regis, and A. cephalonica.

Seventeen native fir populations from the presumed zones of natural hybridization in the Balkan Peninsula were analyzed using headspace needle volatiles and GC-MS/FID analyses. The multivariate statistical analyses revealed clear differentiation between populations of Abies alba and A. cephalonica, suggesting that Silver and Greek Fir are characterized by distinct volatile profiles.

Epicuticular Waxes Provide Insights into Phytochemical Differentiation of Natural Populations of Pinus mugo Turra sensu stricto.

Phytochemical diversity and differentiation of nine native populations of Pinus mugo sensu stricto from Julian Alps, Southern Carpathians and Balkan Peninsula were analyzed in regard to their epicuticular wax compounds. GC/MS and GC-FID analyses of the hexane extracts of needle samples, collected from 118 individuals of P. mugo, revealed the presence of six diterpenes, three primary alcohols and 10 n-alkanes ranging from C to C (except n-alkane C ).

Chemotaxonomic Considerations of the n-Alkane Composition in Pinus heldreichii, P. nigra, and P. peuce.

The n-alkane composition in the leaf cuticular waxes of natural populations of Bosnian pine (Pinus heldreichii), Austrian pine (P. nigra), and Macedonian pine (P. peuce) was compared for the first time.

Terpenes as Useful Markers in Differentiation of Natural Populations of Relict Pines Pinus heldreichii, P. nigra, and P. peuce.

Comparative analysis of terpene diversity and differentiation of relict pines Pinus heldreichii, P. nigra, and P. peuce from the central Balkans was performed at the population level.

Needle Terpenes as Chemotaxonomic Markers in Pinus: Subsections Pinus and Pinaster.

Chemical compositions of needle essential oils of 27 taxa from the section Pinus, including 20 and 7 taxa of the subsections Pinus and Pinaster, respectively, were compared in order to determine chemotaxonomic significance of terpenes at infrageneric level. According to analysis of variance, six out of 31 studied terpene characters were characterized by a high level of significance, indicating statistically significant difference between the examined subsections. Agglomerative hierarchical cluster analysis has shown separation of eight groups, where representatives of subsect.

Geographically Related Variation in Epicuticular Wax Traits of Pinus nigra Populations from Southern Carpathians and Central Balkans - Taxonomic Considerations.

The chemical composition of epicuticular waxes of nine populations from three Pinus nigra J. F. Arnold subspecies (namely subsp.
