The authors tested the ability of 60 free-flying honeybees (Apis mellifera carnica) to discriminate a conditioning odor from an array of 26 simultaneously presented substances. The stimuli included 10 pairs of enantiomers and 6 essential oils. The bees (a) significantly distinguished between 98% of the 540 odor pairs tested, thus showing an excellent overall discrimination performance, and (b) ...
در این مطالعه روشهای محاسبات آغازین برای اثرات حلال و مطالعات nmr برای 8 ماده موثر ضداسترس گیاه جوزهندی بکار گرفته شد. این ترکیبات موثر جوز هندی شامل انانتیومرهای terpineol : ? و? و? و 4 و همچنین geraniol و سه مشتق آن فرمات و استات و بوتیرات محاسبات در سری های پایه متفاوتی شامل 6-311g و 6-311g* و 6-311+g انجام شد. روش میدان واکنش onsiger که شاخه روش میدان واکنش خودالقاء می باشد برای اندازه گیر...
The aim of the study was to examine the antibiofilm activity of selected essential oils (EO): Lavandula angustifblia (LEO), Melaleuca alternifolia (TTO), Melissa officinalis (MEO) and some of their major constituents: linalool, linalyl acetate, alpha-terpineol, terpinen-4-ol. Biofilms were formed by Staphylococcus aureus ATCC 29213 and Escherichia coli NCTC 8196 on the surface of medical biomat...
Acute toxicity studies, physicochemical and GC/MS analyses of Monodora myristica (Gaertn.) Dunal oil
Background: The seeds of Monodora myristica, a tropical plant belonging to the family Annonaceae, are widely used as condiments in preparation number African delicacies, impart or enhance flavour. Their use is largely due volatile and fixed oils contained nuts.Objective: To screen for acute toxicity (LD50) profile, determine physicochemical properties, well carry out GC-MS analysis seed oil myr...
The essential oils obtained from different officinal plants of Lebanon, belonging to the Magnoliophyta division, have been tested for their antiproliferative activity on human erythroleukemic K562 cells. Satureja montana showed the most interesting biological activity in inhibiting the cell growth and inducing erythroid differentiation of K562 cells. The essential oil of Satureja montana was th...
Essential oil from herb and rhizome of Peucedanum ostruthium (L.Koch.) ex DC underwent qualitative and quantitative analyses. The content of the oil obtained by hydrodistillation was 0.95% in the herb and 1.25% in the rhizome (per dry weight basis). Gas chromatography (GC) with MS detection and flame ionisation detection showed that the oil from the rhizome contains 39 compounds, of which 29 we...
Background: Essential oils extracted from plants have been widely used in antimicrobial activity, particularly the Callistemon viminalis, with a high number of essential extracted. Objectives: To identify chemical composition oil derived viminalis and evaluates its activity against selected bacterial fungal strains. Subjects methods: During study, different on some bacteria (Escherichia coli, P...
Objective(s):Dependence and tolerance to opioid analgesics are major problems limiting their clinical application. a-Terpineol is a monoterpenoid alcohol with neuroprotective effects which is found in several medicinal plants such as Myrtus communis, Laurus nobilis, and Stachys byzantina. It has been shown that some of these medicinal plants such as S. byzantina attenuate dependence and toleran...
