The effects of methanol, ethanol, dimethyl sulfoxide (DMSO), and acetonitrile were studied in vitro on nine individual, cDNAexpressed cytochrome P-450 activities (phenacetin O-deethylase for CYP1A1 and CYP1A2, coumarin 7-hydroxylase for CYP2A6, testosterone 6beta-hydroxylase for CYP3A4, 7-ethoxy-4-trifluoromethylcoumarin deethylase for CYP2B6, paclitaxel 6alpha-hydroxylase for CYP2C8, diclofena...

The aim of the present study was to investigate the antimicrobial activity and phytochemical screening of Carica papaya, Piper nigrum and Datura stramonium plant extracts. Ethanol and Methanol were used as the solvents for extraction. The antimicrobial activities of these plant extracts were tested against the drug resistant Gram-positive and Gram-negative bacterial strains. The bacteria used i...

Catechinone hair dyestuff was produced chemically from (+)-catechin by the oxidation with O2 in basic water/alcohol mixed solution. The effects of reaction conditions such as basicity, sorts of added base, temperature, alcohol molar fraction of solvent and sorts of added alcohols on the catechinone formation were studied in order to increase the efficiency of the dyestuff production. The amount...

The infrared absorption spectra of methanol, ethanol, and n-propanol have been measured with prism instruments. Studies have been made of the vapors and of several dilute solutions. The methanol spectra, between 2 to 15 microns, prpvided a direct comparison with the other two alcohols and confirmed earlier work on the existence of a number of lowintensity bands. The two other alcohols were stud...

Cyperus rotundus, Caesalpinia bonducella, Tinospora cordifolia, Gardenia gummifera, Ailanthus excelsa, Acacia arabica, Embelia ribes and Ventilago maderspatana from Melghat forest were screened for their antibacterial potential against Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, Proteus vulgaris, Salmonella typhi, Shigella flexneri, Salmonella paratyphi, Salmonella typhimuri...

The study was conducted to investigate the optimum conditions for biodiesel formation from pure (virgin) soybean cooking oil (PSCO) and waste soybean cooking oil (WSCO) coming after alkaline transesterification process in combination with methanol, ethanol and 1-butanol. Some important variables such as volumetric ratio, types of reactants and catalytic activities were selected to obtain a high...

the subject handled in this study is the determination of antioxidant activities of extracts obtained from the urginea maritima (l.) baker plant’s leaves and tubers. extractions which were obtained using various solvents as methanol, ethanol, acetone and benzine. the antioxidant activity of the extracts was determined using β-karotene-linoleic acid system. moreover, the free radical scavenging ...

Ethanol and fomepizole are used as antidotes for poisoning with ethylene glycol or methanol. Both ethylene glycol and methanol are metabolized by the enzyme alcohol dehydrogenase. Ethanol is a substrate for alcohol dehydrogenase and fomepizole is an inhibitor of this enzyme. This review pays attention to the differences between ethanol and fomepizole. The advantages and disadvantages of both an...

This research was undertaken to investigate the influence of extraction parameters during microwave-assisted extraction on total phenolic content, total flavonoids, total hydroxycinnamic acids and total flavonols of blackthorn flowers as well as to evaluate the antioxidant capacity by two different methods (2,2-diphenyl-1-picrylhydrazyl free radical scavenging capacity and ferric reducing antio...

The present study was designated to evaluated the antimicrobial activities of methanol, ethanol, hexane, ethyl acetate, aqueous, mixture methanol/water and ethanol/water extracts of Pentadiplandra brazzeana, Erythrina sigmoïdea, Petersianthus macrocarpus, Clerodendrum umbellatum , Sida acuta , Eleusine indica , Bridelia micrantha and Musanga cecropioides which are plants used as traditional fol...
