Plants of the family Anacardiaceae have a long history of use by various peoples for medicinal and other purposes. Cotinus coggygria, also known as the “smoke tree”, is one of the two species constituting a small genus of the family Anacardiaceae, viz., C. coggygria Scop. (syn.: Rhus cotinus L.) The Iranian smoke tree, plant material air-dried C. coggygria we...
Medicinal plante Borazambol with the scientific name of Perovskia abrotanoides Karel. belongs to the family Lamiaceae. It is growing wild in the margin of mountainous roads of arid and cold climate of north Iran. It is for a long time that indigenous people by different methods in traditional medicine use its products in preventing and curing diseases. In this research, essential oils of Perovs...
Hydro-distilled volatile oils from the leaves of Ocimum gratissimum L. (Lamiaceae) of 13 populations of different silvicultural zones were evaluated for antimicrobial activity against gram positive (Staphylococcus aereus, Bacillus spp.) and gram negative (Escherichia coli, Pseudomonas aeruginosa, Samonella typhi, Klebisiella pneumoniae, Proteus mirabilis) bacteria and a pathogenic fungus, Candi...
This study investigated the fumigant toxicity of oriental sweetgum (Liquidambar orientalis) and valerian (Valeriana wallichii) essential oils and their components against the Japanese termite (Reticulitermes speratus). The fumigant toxicity of oriental sweetgum and valerian oil differed significantly according to exposure time. Oriental sweetgum showed toxicity at short exposure times (2 days),...
The essential oil isolated from Turkish tarragon (Artemisia dracunculus) by hydrodistillation was analyzed by GC-MS. Thirty compounds representing 99.5% of total oil were identified. The predominant components in the oil were (Z)-anethole (81.0%), (Z)-beta-ocimene (6.5%), (E)-beta-ocimene (3.1%), limonene (3.1%), and methyleugenol (1.8%). The antibacterial and antifungal activities of the essen...
Abstract. Biogenic volatile organic compounds (BVOCs) emitted by plants represent the largest source of non-methane hydrocarbon emissions on Earth. Photochemical oxidation BVOCs represents a significant pathway in production secondary aerosol (SOA), affecting Earth's radiative balance. Organic nitrates (RONO2), formed from presence NOx, important precursors and affect oxidative capacity atmosph...
The chemical composition of oregano essential oil of different origin extracted from oregano plants grown in south-eastern Poland was analysed using the gas chromatography mass spectrometry (GC-MS) and gas chromatography flame ionization detector (GC-FID). The dominant compound was sabinene; its percentage proportion ranged from 10.85% to 25.46%, depending on the ecotype studied. Moreover, the ...
BACKGROUND Biological control plays a key role in reducing crop damage by Tuta absoluta (Meyrick) and Trialeurodes vaporariorum (Westwood), which cause huge yield losses tomato (Solanum lycopersicum L.). The mirid predator Nesidiocoris tenuis (Reuter) preys heavily on these pests, with satisfying levels greenhouses. Although N. is known to be attracted volatiles of plants infested T. whitefly, ...
Salinity is an abiotic stressor that greatly influences crop growth and yield. Scientists are always exploring diverse methods to combat salinity depression. Here, we conducted a greenhouse experiment study the effects of NaCl (0, 50, 100 mM) under foliar spray with zinc-oxide, nano iron-chelate, magnetized-Fe, graphene-oxide on tarragon. The results revealed treatment graphene showed highest K...
