Phytochemistry and Micromorphology of Epicuticular Waxes in Four Juniper Species With Fragmented Distribution in the Balkans.

The cuticle is important in the interaction between the plant and its environment, especially in the dry areas. Four species of junipers from the section Sabina wild growing in the Balkans were selected to study leaf wax composition using GC/MS and GC-FID and its surface morphology under SEM to understand the correlation between the distribution and/or habitat of these species and their cuticles. SEM micrographs showed continuous, smooth epicuticular layers with crusts in all species but with a species-specific distribution of different 3D crystalloid types and different cuticle thickness.

Phytochemical and biological investigations on Centranthus kellereri (Stoj., Stef. & T. Georgiev) Stoj. & Stef. and C. ruber (L.) DC. and their potential as new medicinal and ornamental plants.

Introduction: Centranthus kellereri is a Bulgarian endemic plant species, found only in two locations in the world: The Balkans Mountains (Stara Planina), above the town of Vratsa, and The Pirin Mountains, above the town of Bansko, Bulgaria. Being endemic and endangered species precluded any significant research on it. The hypothesis of this study was that the populations of C.

L. as a Sprout Suppressor in L. and an Alternative to Synthetic Pesticides.

The goal of this research was to screen plant essential oils (EOs) as sprout inhibitors or suppressors in potato ( L.). Three controlled environment experiments were conducted to screen 18 EOs and several pure compounds as sprout inhibitors.

Phytochemical Variability of Essential Oils of Two Balkan Endemic Species: Velen. and Wierzb. ex Heuff. (Lamiaceae).

and (Lamiaceae) are Balkan endemic plant species, and the composition of their essential oil (EO) is highly variable. The aim of the present study was to establish: (1) the EO variability in two populations of (the intrapopulation), and (2) the EO variation in between nine populations (interpopulation) from Bulgaria and two from Serbia. The EOs of two species were obtained from aboveground plant parts by hydrodistillation and were analyzed by GC/MS/FID.

Chemical Profile and Antimicrobial Activity of the Essential Oils of (L.) Moench. and (Roth.) G. Don.

This study compared the essential oils (EO) composition of (Bulgarian populations) with that of the cultivated species . The EO composition of and were analyzed via gas chromatography. In general, 75 components were identified in EO and 79 in EO.

Phytochemical Investigation and Reproductive Capacity of the Bulgarian Endemic Plant Species Boiss. (Lamiaceae).

Boiss (Lamiaceae) is a Bulgarian endemic species. Overall, the essential oil (EO) composition of was different from that of the other species reported in the literature. The main EO constituents of were ()-caryophyllene, germacrene D, and caryophyllene oxide.

Biological Activity of Essential Oils of Four Juniper Species and Their Potential as Biopesticides.

The objective of this study was to assess the biological activity of essential oils (EOs) of four species obtained via two different distillation methods and their potential as biopesticides. The studied factors were juniper species ( L., L.

Essential Oil Composition and Bioactivity of Two Juniper Species from Bulgaria and Slovakia.

M. Bieb and L. contain essential oil (EO), while also contains podophyllotoxin, which is used as a precursor for anti-cancer drugs.

Industrial, CBD, and Wild Hemp: How Different Are Their Essential Oil Profile and Antimicrobial Activity?

Hemp ( L.) is currently one of the most controversial and promising crops. This study compared nine wild hemp ( spp.

Comparative Study on the Phytochemical Composition and Antioxidant Activity of Grecian Juniper ( M. Bieb) Unripe and Ripe Galbuli.

Grecian juniper ( M. Bieb.) is an evergreen tree and a rare plant found in very few locations in southern Bulgaria.

Grinding and Fractionation during Distillation Alter Hemp Essential Oil Profile and Its Antimicrobial Activity.

The hypothesis of this study was that we can modify the essential oil (EO) profile of hemp ( L.) and obtain fractions with differential composition and antimicrobial activity. Therefore, the objective was to evaluate the effects of grinding of hemp biomass before EO extraction and fractionation during distillation on EO profile and antimicrobial activity.
