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 ...

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...

The essential oils were isolated by hydrodistillation from the hairy roots (HR) and roots of soil-grown plants (SGR) of Rhaponticum carthamoides and were analyzed by GC-MS method. In the both essential oils 62 compounds were identified. The root essential oils showed the differences in the qualitative and quantitative composition. The sesquiterpene hydrocarbons (55-62%) dominated in both essent...

In this study we evaluated and reported repellent effects of essential oils from Thai plants against 4 mosquito vectors: Aedes aegypti, Ae. albopictus, Anopheles. dirus and Culex quinquefasciatus under laboratory conditions using human volunteers. The essential oils were extracted from 18 plant species, belonging to 11 families, and the oils were then prepared as 10% solution in absolute ethano...

Twenty seven essential oils, isolated from plants representing 11 families of Portuguese flora, were screened for their nematicidal activity against the pinewood nematode (PWN), Bursaphelenchus xylophilus. The essential oils were isolated by hydrodistillation and the volatiles by distillation-extraction, and both were analysed by GC and GC-MS. High nematicidal activity was achieved with essenti...

The study investigated cytotoxicity of essential oils from four medicinal plants (Bidens pilosa, Ocimum gratissimum, Cymbopogon nardus, and Zanthoxylum chalybeum) on human gingival fibroblasts and their effects on proinflammatory mediators' secretion. Cytotoxicity of essential oils was investigated using 3-(4, 5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide assay. Effects of essential ...
