Plant oils have attracted interest for centuries as natural remedies in treatment of various diseases. The Inula verbascifolia (Willd.) Hausskn.isgrowing wild plant in Bosnia and Herzegovina. Aromatic natural oils are one of the most significant sources of natural organic components. The natural vegetable oil of the selected plant (Inula verb.) was obtained by the hydrodistillation method. A comparison was made between the fragrant vegetable oil from the aerial parts of the plant in the flowering period (summer) and after the flowering period (autumn). In this study, chemical compounds were tested, comparing the content and composition of natural oils from the plant Inula verbascifolia. The aerial parts of the plant contained a fragrant and yellow essential oil. The identified 125 constituents accounted for 86.87% and 88.38% of the oil. The dominant compounds of both EOs were tridecanal, (3Z)- hexenyl benzoate, α-murolol, hexadecanoic acid, linalool and undecanal. Since essential aromatic oils possess a number of antimicrobial properties, an analysis of antimicrobial activity was also performed in this work. The antimicrobial activity of a mixture of EOs was determined on selected ATCC strains of microorganisms. Results of antimicrobial activity indicated that all used the microorganisms were sensitive to the EO. No data about antimicrobial activity of Inula verbascifolia has been published yet.

Background: Fruit is a rich source of biologically active compounds which are essential for the human organism. It is also important to highlight the various fruit products which can be considered important constituents of nutrition; among these products, the authors would like to highlight fruit wines. Objectives: The aim of this study was to determine the phenolic profile, antioxidant and in vitro activity of analysed fruit wine. Methods : Fruit wines were produced from black chokeberry in different controlled conditions of micro vinification. Wines were produced with the addition of sugar and enzymatic preparation and without addition. Two different yeasts were used in separate fermentations. Identification and quantification of phenolic compounds were conducted by UPLC TQ-MS/MS

Origanum compactum, an endemic Moroccan medicinal herb, possesses many different activities such as antibacterial, antifungal, antioxidant and anticancer. The aim of this study was to investigate the stability and antifungal activity of liposomal dispersion with this essential oil. Liposomal dispersion stability was evaluated by testing the vesicle size, polydispersity index and zeta potential. It was also examined the in vitro release of thymol and carvacrol from liposomal dispersion. The major components of this essential oil were carvacrol (58.4%), thymol (12.5%) and γ-terpinene (10.7%). Origanum compactum essential oil showed a strong antifungal activity, and the inhibition zones ranged from 24 to 45 mm. After 210 minutes, 80.88% thymol and 16.67% carvacrol were released. Stability assessment was performed for three months and the liposomal dispersion showed a good stability.
