background: in current study, chemical composition and antibacterial activity of leaves and flowers essential oils of origanum vulgare ssp. gracile against four food-borne pathogens including  escherichia coli, listeria monocytogenes, salmonella thyphimurium and staphylococcus aureus were examined. methods: the different organs (leaves and flowers) of o. vulgare ssp. gracile were harvested at f...

constant use of chemical fungicides has faced to increasing public concern regarding contamination of perishables with fungicidal residues, and proliferation of resistance in the pathogen populations. so recent researches in this area has focused on the development and evaluation of alternative control strategies to reduce dependency on synthetic fungicides. accordingly, in this research in vit...

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)...

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 ...
