This research was aimed at investigating the essential oil production, chemical composition and biological activity of a crop of pink flowered oregano (Origanum vulgare L. subsp. vulgare L.) under different spatial distribution of the plants (single and binate rows). This plant factor was shown to affect its growth, soil covering, fresh biomass, essential oil amount and composition. In particul...

conclusions based on these observations, wide variation is detected in the chemical composition of the oil obtained from the same plant in different seasons. materials and methods the oil was extracted by hydro-distillation from two samples collected in different seasons, and analyzed by gc-fid and gc-ms. results in total, 18 and 20 components were identified and quantified in the oil of summer...

 The study aims to determine the influence of frying (shallow and deep) with olive, canola and sunflower oil on fatty acid composition of silver carp. Frying by olive oil and canola oil increased the monounsaturated fatty acids (MUFA) significantly (p<0.05) that consequently decreased saturated fatty acids (SFA), polyunsaturated fatty acids (PUFA) and ω-3 fatty acids. Frying by sunflow...

Redbay ambrosia beetle, Xyleborus glabratus Eichoff, is an exotic species to North America vectoring a deadly vascular wilt disease of redbay [Persea borbonia (L.) Spreng], swampbay [P. palustris (Raf.) Sarg.], avocado (P. americana Mill.), and sassafras [Sassafras albidum (Nutt.) Nees]. Xyleborus glabratus is attracted to manuka oil lures, which are commercially available, and phoebe oil. Vari...

The alpha-linolenic acid (ALA)-diacylglycerol (DAG) oil is an edible oil enriched with DAG (>80%) and ALA (>50%). Although DAG oil, which mainly consists of oleic and linoleic acids has no genotoxic concerns, the fatty acid composition could affect the chemical property of DAG. Therefore, the purpose of this study was to evaluate the genotoxicity of ALA-DAG oil using standard genotoxicity tests...

abstract: the object of this study is to extract the oil from millets and evaluate the chemical properties of the extracted oil. commercial millet oil was obtained by cold solvent extraction adopting soxhlet procedure. quantitative and qualitative tests concerned with the non-saponifiable matter, fatty acid composition, phosphorus content representing total phospholipids, refractive index, pero...

The leaves of Arum conophalloides (Araceae) were used in some west areas of Iran as a dessert. The aerial parts of the herb were collected from Sahneh Mountains, Kermanshah Province, West of Iran and was hydrodistilled by Klevenger-type apparatus. Composition of the essential oil was determined by GC and GC/MS. Totally, 18 components (92% of total essential oil) were identified. The oil contain...

This is the first on the modulation of norfloxacin antibiotic activity by the volatile compounds of an essential oil. We report the chemical composition and antibiotic modifying activity of the essential oil extracted from the leaves of Croton zehntneri Pax et Hoffm (variety estragole), using the minimal inhibitory dose method and gaseous contact. The leaves of Croton zehntneri Pax et Hoffm (Eu...

Satureja genus presents 12 aromatic species in Iran, eight of which are endemic. Because of the several usages of Satureja species or their oils in different industries, we were interested to study the oil content and composition of Iranian Satureja species. In this research, the essential oil content and composition of two endemic species (S. edmondi and S. isophylla) were investigated. Essent...

background and objectives : the aim of this study was to evaluate the chemical composition and antimicrobial activity of satureja hortensis and trachyspermum copticum essential oils against different kinds of microorganisms in vitro. material and methods : the antimicrobial activity was evaluated by micro broth dilution assay and analysis of essential oils chemical composition by gc and gc/ms a...
