    Phyton-International Journal of Experimental Botany, Vol.93, No.4, pp. 725-744, 2024, DOI:10.32604/phyton.2024.048110

    Abstract In this work, we investigated aroma volatiles emanated by dry roots, stems, leaves, flowers, and fruits of Cardaria draba (L.) Desv. growing wild in Tunisia and its aerial part essential oils (EOs) composition. A total of 37 volatile organic compounds (96.7%–98.9%) were identified; 4 esters, 4 alcohols, 7 hydrocarbons, 12 aldehydes, 5 ketones, 1 lactone, 1 organosulfur compound, 2 organonitrogen compounds, and 1 acid. The hydrocarbons form the main group, representing 49.5%–84.6% of the total detected volatiles. The main constituent was 2,2,4,6,6-pentamethylheptane (44.5%–76.2%) reaching the highest relative percentages. Forty-two compounds were determined in the two fractions… More >

    Development of Gelatin-Based Active Packaging and Its Application in Bread Preservation

    Hui Zheng1,2, Xiaohan Chen2, Li Li2, Dawei Qi1, Jiale Wang1, Jiaying Lou1,*, Wenjun Wang1,*

    Journal of Renewable Materials, Vol.11, No.10, pp. 3693-3709, 2023, DOI:10.32604/jrm.2023.027748

    Abstract The issue of plastic pollution has attracted widespread social attention. Gelatin is valued as a degradable bio-based material, especially as an edible active packaging material. However, the commonly used solution-casting filmforming technology limits the mass production of gelatin films. In order to improve the production efficiency and enhance the commercial value of gelatin films, in this study, fish gelatin (FG) particles were successfully blended with essential oils (EOs) to prepare active films by melt extrusion technique, a common method for commercial plastics, and applied to bread preservation. FG and EOs showed good compatibility with each… More > Graphic Abstract

    Essential oil and phototoxic compounds in Clibadium surinamense L. and Montanoa grandiflora D.C. (Asteraceae)

    Pérez-Amador* MC, V Muñoz*, A Noyola*, F García-Jiménez**

    Phyton-International Journal of Experimental Botany, Vol.75, pp. 145-150, 2006, DOI:10.32604/phyton.2006.75.145

    Abstract Two Asteraceae species, Clibadium surinamense L. and Montanoa grandiflora D.C., were analyzed to determine the composition of the essential oil and to search for phototoxic compounds.
    Three parts of the plants were studied, inflorescence, stems and leaves. Intra and interspecific differences were found in the essential oil composition, which was determined by gas chromatography.
    In the chromatographic profiles, run for phototoxic compounds, spots for these products were present in the Clibadium surinamense extracts, but were absent in Montanoa grandiflora.
    From the hexane extract of Clibadium surinamense inflorescence 2 new polyacetylene esters were isolated, ichtyothereol capric ester and its More >

    Antifungal activity of various essential oils against Saccharomyces cerevisiae depends on disruption of cell membrane integrity


    BIOCELL, Vol.41, No.1, pp. 13-18, 2017, DOI:10.32604/biocell.2017.41.013

    Abstract Antifungal activity and mode of action of nine essential oils (EOs) against S. cerevisiae cells were examined. Antifungal effects of commercial lemon peel, orange peel, tea tree, turpentine, rosemary, peppermint, thyme, oregano and clove oils were determined through Minimum Inhibitory Concentration (MIC), Minimum Fungicidal Concentration (MFC) and inhibition zone measurements. The most effective oil was turpentine oil. Orange peel, thyme and oregano oils were also effective, according to MIC and MFC. Inhibition zone measurements, also revealed oregano, orange peel, thyme, turpentine and clove oils as most efficient ones. Later, membrane damage of yeast cells was studied… More >
