The objective of this study was to evaluate the antifungal activity of essential oil (EO) of Eucalyptus camaldulensis Dehnh. against five Fusarium spp. commonly associated with maize. The essential oil had been extracted by steam distillation in a modified Clevenger-type apparatus from leaves of E. camaldulensis and their chemical composition characterized by gas chromatography mass spectrometr...

background: the genus eucalyptus (family myrtaceae) comprises well-known plants of over 600 species of trees. although most of the plants are native to australia, numerous species have been introduced to other parts of the world, including iran, as economic and ornamental trees in forest trial provenances, where the plants have become source of important fast-growing hardwood trees and eucalypt...

The chemical composition of the essential oil of Etlingera yunnanensis rhizomes and its contact and repellent activities against Tribolium castaneum (Herbst) and Liposcelis bostrychophila (Badonnel) were investigated. The essential oil obtained from E. yunnanensis rhizomes with hydrodistillation was performed by gas chromatography-flame ionization detection and gas chromatography-mass spectrome...

The chemical profiles of Rosmarinus officinalis L. essential oils, collected from five distinct geographical regions in Palestine, were determined using GC-MS. major phytochemical classes R. EOs monoterpene hydrocarbon (24.81–78.75%) and oxygenated monoterpenoids (19.01–73.78%), with 1,8-cineole (4.81–37.83%), α-pinene (13.07–51.36%), camphor (11.95–24.30%) being the most abundant components st...

The ability of secondary organic aerosol (SOA) produced from the ozonolysis of α-pinene and monoterpene mixtures (α-pinene, β-pinene, limonene and 3-carene) to become cloud droplets was investigated. A static CCN counter and a Scanning Mobility CCN Analyser (a Scanning Mobility Particle Sizer coupled with a Continuous Flow counter) were used for the CCN measurements. Consistent with previous st...

many parameters affect essential oil yield and chemical composition of aromatic plants. for obtaining the highest quantity and quality of essential oil, it is necessary to know the proper methods of drying and distillation. the aim of this research was to investigate the influence of drying and extraction methods on the yield and chemical composition of the essential oil of eucalyptus sargentii...

Existing parameterizations tend to underpredict the α-pinene aerosol mass fraction (AMF) or yield by a factor of 2–5 at low organic aerosol concentrations (<5μg m−3). A wide range of smog chamber results obtained at various conditions (low/high NOx, presence/absence of UV radiation, dry/humid conditions, and temperatures ranging from 15–40C) collected by various research teams during the last d...

The intensive use of antibiotics in aquaculture has resulted increased resistance among fish pathogens, and this situation led researchers to investigate the antibacterial properties natural resources. present study focused on an essential oil isolated from leaves Eucalyptus camaldulensis as a potential that could be used against Aeromonas caviae. Eighteen compounds were identified oil, represe...
