in this research, fumigation efficiency, repellency and persistence of citrus essential oils extracted from dried peels of orange, bitter orange and mandarin (cultivars: satsuma, page, clemantin) were investigated against adults of confused flour beetle tribolium confusum duval. the essential oils were extracted by using clevenger apparatus. 40 ml glass container as bioassay chamber and filter ...

The aim of the present work was to determine the in vitro effect of T. vulgaris and O. vulgare essential oils against E. granulosus protoscoleces and cysts. Essential oils were added to the medium resulting in thymol final concentrations of 10 μg/mL. The essential oils had a time-dependent effect provoking the complete loss of protoscolex viability after 72 days of postincubation. The results w...

Antibacterial properties and chemical characterization of the essential oils from summer savory (Satureja hortensis) extracted by microwave-assisted hydrodistillation (MAHD) were compared with those of the essential oils extracted using the traditional hydrodistillation (HD) method. While MAHD at 660 W required half as much time as HD needed, similar antibacterial efficacies were found from the...

objectives: the purpose of this study was to assay the antifungal activity of selected essential oils obtained from plants against both fluconazole (flu)-resistant and flu-susceptible c. albicans strains isolated from hiv positive patients with oropharyngeal candidiasis (opc). materials and methods: the essential oils were obtained by hydrodistillation method from myrtus communis (my. communis)...

The purpose of the present study was to evaluate carboxymethyl cellulose (CMC) coated polypropylene (PP) films containing Zataria multiflora (ZEO) essential oils (4%) as an antimicrobial packaging for chicken breast stored at 4 °C. To increase PP film hydrophilicity, it was treated by atmospheric cold plasma prior to coating by CMC. Then, different films including PP, PP/CMC, PP/CMC containing ...

background and objectives: essential oils (eos) possess a wide range of significant properties including antiphlogistic, spasmolytic and antinociceptive effects. in this study, we use eos from thymus daenensis, thymus caramanicus and ziziphora clinopodiodes. materials and methods: in this study, the plants were collected from the botany department, were air dried, grinded and set for extraction...

The chemical and analgesic comparison of essential oils o Congo was investigated. The Chemical analysis wa carried out by u the two essential oils while acetic acid-induced writhings, hot plate activity. The results showed that the two essential oils exhibite writhings, however, the essential oil of Benin induced more significa specie showed more effect in the tail flick test. These observation...

Essential oils are complex mixtures of hydrocarbons and their oxygenated derivatives arising from two different isoprenoid pathways. Essential oils are produced by glandular trichomes and other secretory structures, specialized secretory tissues mainly diffused onto the surface of plant organs, particularly flowers and leaves, thus exerting a pivotal ecological role in plant. In addition, essen...

objective: origanum vulgare l. is rarely cultivated in iran but it is the only species of the origanum genus growing wild in this country. o.vulgare l. is widely spread all over the country. in this study, parameters of content, composition and antioxidant activity of the essential oils of domestic and wild iranian oregano populations were compared  with one another. materials and methods: the ...

This study was designed to examine for the first time the antimicrobial and antioxidant activities of essential oils and organic extracts of Tunisian Citrus aurantium. Essential oils extracted by hydrodistillation from the peels, leaves and flowers were characterized by GC–MS. It results in the identification of three chemotypes: limonene (87,02 %), linalyl acetate (53,76 %) and linalool (39,74...
