Volatile components in the extracts of basil leaves (Ocimum basilicum L.) were identified by gas chromatography/mass spectrometry (GC/MS) with electron ionization (EI) mode. The major volatile under investigation are α-pinene, sabinene, β-pinene, d-limonene, eucalyptol, l-linalool and estragole. Electron mass spectra these compounds have been obtained investigated. Furthermore, semi-empirical MNDO [Modified Neglect Diatomic Overlap] method was used to calculate thermochemical data for...
Abstract In the present study, biomass produced by fennel plants ( Foeniculum vulgare Mill.) was converted to yield bioactive chemicals, and hydrodistillation method used extract essential oils (EOs) from both leaves umbels. The antifungal activity of EOs tested using bioassay against development Fusarium oxysporum MW854649 Alternaria solani MT279570. Molecular spectroscopic detection techniques were evaluate EO products gas chromatography–mass spectrometer (GC–MS) Fourier transform infrared...
The volatile constituents of the essential oil local Pelargonium graveolens growing in Egypt was investigated by gas chromatography–mass spectrometry (GC–MS), and main were citronellol (27.67%), cis-Menthone (10.23%), linalool (10.05%), eudesmol (9.40%), geraniol formate 6.87%, rose oxide (5.77%), which represent major components obtained GC total ion chromatogram. structural determination constitutes based on their electron ionization mass spectra have been investigated. MS these compounds...
The present study described the possibility of using wood-treated oil-fungicide lemon-scented gum (Corymbia citriodora) from newly emerged leaves and unripened fruits against infestation Fusarium culmorum, Rhizoctonia solani Penicillium chrysogenum. Air-dried wood samples Melia azedarach were treated with extracted oils C. citriodora. main chemical constituents identified in essential oil (EO) citronellal (55.31%), citronellol (21.03%) isopulegol (10.79%), while α-pinene (17.86%), eudesmol...
The most important uses of old fabrics include clothing, mummification, and bookbinding. However, because they are predominantly constructed natural materials, particularly susceptible to physical chemical deterioration brought on by fungi. treatments that typically used preserve textiles focus the use synthetic fungicides, which have potential be dangerous for both human health environment. Essential oils (EOs), safe environment no negative effects health, been widely advocated as an...
In the present work, shrub W. somnifera was used as a source for extraction of bioactive molecules. Leaves were extracted by ethanol and analyzed Gas Chromatography-Mass Spectrometry (GC-MS) High-Performance Liquid Chromatography (HPLC). By GC-MS analysis, highest identified compounds 2,6-dimethyl-N-(2-methyl-α-phenylbenzyl)aniline, 4-Aminoheptane, n-undecanophenone, 2-cyclohexyl-4-hydroxymethyl-octahydrobenzo[e][1,2] oxazine-3-carbonitrile, octadecanoic acid 3-octadecyloxypropyl ester, with...
Sparfloxacin is a broad spectrum antibacterial fluoroquinolone against some microorganisms including gram-positive and gram-negative bacteria exhibits moderate activity anaerobes mycobacteria. well tolerated the intake of food has no adverse effect on pharmacokinetic features (Blondeau 1999, Stahlmann et al. 1998). For medical important this drug author have been study its structure by recording investigate electron ionization (EI) mass spectra at different energies 70 15 eV. Also, chemical...
Theoretical studies on some chlorinated pesticides compounds namely:Heptachlor, Heptachlorepoxide and Chlordane as a first group, Aldrin Endrin second DDT, Methoxychlor third were performed using semi-empirical quantum chemical calculation.Modified Neglect of Diatomic Overlap MNDO method was used to investigate the effect positional variation chlorine oxygen atoms electronic structure properties studied pesticides.The optimization parameters such heats formation, total energies, energy,...
Biodiesel production from waste vegetable used oils have a great interest as substitute for petroleum diesel to reduce dependence on imported and provide an alternate sustainable source fuel with more benign environmental properties. In the present research biodiesel was prepared three samples [mixture (sunflower 75% + soybean 25%), sunflower cotton] (collected wastes Egyptian local restaurants) by transesterification. The reference produced of studied were chemically characterized gas...
