AB  - Abies cephalonica Loudon consists one of the three fir species occurring in Greece. The aim of this study was to evaluate the chemical composition of the essential oil (EO) from needles of A. cephalonica from Mt. Aenos (Kefalonia Island, Greece) and to investigate its antimicrobial activity. The EO was obtained by hydrodistillation and 68 constituents corresponding to 99.4% of the EO were identified by using GC-MS analysis. The major chemical category of the volatile compounds were the monoterpene hydrocarbons (63.9%), followed by oxygenated monoterpenes (20.2%). In particular, the main components were beta-pinene (26.9%), bornyl acetate (12.5%), alpha-pinene (10.1%), camphene (9.2%), limonene (8.1%), gamma-eudesmol (8.1%) and beta-phellandrene (5.8%). To the best of our knowledge, the present study is the first research, reporting the phytochemical profile and the antimicrobial potential of the EO of A. cephalonica from this distinct geographic area.

AB  - Food poisoning is a common cause of illness and death in developing countries. Essential oils (EOs) could be effective and safe natural preservatives to prevent and control bacterial contamination of foods. However, their high sensitivity and strong flavor limit their application and biological effectiveness. The aim of this study was firstly the chemical analysis and the antimicrobial evaluation of the EOs of Origanum onites L. and Satureja thymbra L. obtained from Symi island (Greece), and, secondly, the formulation of propylene glycol-nanovesicles loaded with these EOs to improve their antimicrobial properties. The EOs were analyzed by GC-MS and their chemical contents are presented herein. Different nanovesicles were formulated with small average sizes, high homogeneity, and optimal ζ-potential. Microscopic observation confirmed their small and spherical shape. Antibacterial and antifungal activities of the formulated EOs were evaluated against food-borne pathogens and spoilage microorganisms compared to pure EOs. Propylene glycol-nanovesicles loaded with O. onites EO were found to be the most active formulation against all tested strains. Additionally, in vitro studies on the HaCaT cell line showed that nanovesicles encapsulated with EOs had no toxic effect. The present study revealed that both EOs can be used as alternative sanitizers and preservatives in the food industry, and that their formulation in nanovesicles can provide a suitable approach as food-grade delivery system.
