Thin films of plasma polymerised linalyl acetate (PLA) were fabricated and their electrical properties investigated. The high frequency dielectric constant was determined using the split post dielectric resonator (SPDR) technique at frequencies of 10 GHz and 20 GHz and compared with the low frequency dielectric constant found from capacitive measurements of metal-insulator-metal (MIM) structure...

The antifungal activity of the essential oil of Lavandula angustifolia Mill. (lavender oil) and its main components, linalool and linalyl acetate, was investigated against 50 clinical isolates of Candida albicans (28 oropharyngeal strains, 22 vaginal strains) and C. albicans ATCC 3153. Growth inhibition, killing time and inhibition of germ tube formation were evaluated. The chemical composition...

Achillea millefolium L. is a member of the Asteraceae family and has been used in folk medicine in many countries. In this study, 19 compounds in A. millefolium essential oil (AM-EO) have been identified; the major components are artemisia ketone (14.92%), camphor (11.64%), linalyl acetate (11.51%) and 1,8-cineole (10.15%). AM-EO can suppress the inflammatory responses of lipopolysaccharides (L...

The compositions of essential oils (EOs) from Spanish marjoram (Thymus mastichina L.) grown in several bioclimatic zones of Murcia (SE Spain) were studied to determine their absolute and relative concentrations using gas chromatography-mass spectrometry. 1,8-Cineole and linalool were the main components, followed by α-pinene, β-pinene and α-terpineol. (-)-Linalool, (+)-α-terpineol and (+)-α-pin...

Linalool 1 is an odorant that is commonly perceived as having a pleasant odor, but is also known to elicit physiological effects such as inducing calmness and enhancing sleep. However, no comprehensive studies are at hand to show which structural features are responsible for these prominent effects. Therefore, a total of six oxygenated derivatives were synthesized from both 1 and linalyl acetat...

Carboxylesterases containing the sequence motif GGGX catalyze the hydrolysis of esters of chiral tertiary alcohols, albeit with only low to moderate enantioselectivity, for three model substrates (linalyl acetate, methyl-1-pentin-1-yl acetate, 2-phenyl-3-butin-2-yl acetate). In order to understand the molecular mechanism of enantiorecognition and to improve enantioselectivity for this interesti...

Tuta absoluta is a pest of importance: quick to disperse and difficult control due the cases resistance insecticide active ingredients. Thus, studies using essential oils (EOs) search for new molecules should be intensified. The objective present study was evaluate toxicity EOs from Citrus aurantifolia (lime), aurantium (petitgrain) bergamia (bergamot) its major compounds against T. in topical ...
