Research identifying connections between the gastrointestinal flora and human health has developed at a rapid pace. Several studies link the gut microbiome to a variety of biological functions beyond the gastrointestinal tract. Changes in our diets, including the consumption of artificial sweeteners, have profound effects on the composition of the gut microbiome and can, in turn, affect brain f...

Jiaogulan (Gynostemma pentaphyllum; GP) contained a saponin glycoside which was related to ginseng saponin. The purpose of this study was to identify the main saponin in water extract GP compared to methanol and ethanol extract. The sample was prepared by alkaline cleavage, trimethylsilyl (TMS) derivatization and gas chromatographic-mass spectrometric (GC-MS) analysis comparison with standard g...

Colloidal cubic silicon carbide (SiC) nanocrystals with an average diameter of 4.4 nm have been fabricated by anisotropic wet chemical etching of microsized cubic SiC powder. Fourier transform infrared spectra show that these cubic SiC nanocrystals contain carboxylic acid, SiH, CH, and CHx groups. UV/Vis absorption and photoluminescence (PL) spectroscopy clearly indicate that water and ethanol ...

using the evaporating method, the solubility of potassium nitrate was determined in various mixtures containing water and ethanol at 25°c. the results show that the solubility of kno3 decreases with increasing the mass percent of ethanol in the mixtures. this trend is along with decreasing the dielectric constant of water+ethanol mixtures. moreover, it can be concluded that the totqal solubilit...

Because many of the organophosphates used as anticholinesterases are insoluble in water, it is usual to dissolve them in water-miscible organic solvents in order to study their inhibition of the enzyme both in v&o and in vivo. Ethanol is commonly used for this purpose (1, 2), and, because it is an inhibitor of the enzyme, the control samples are treated with a similar level of the solvent. The ...

Serum Albumin is the most abundant protein in blood plasma. Its two major roles are maintaining osmoticpressure and depositing and transporting compounds. In this paper Albumin-Ethanol/Water solutionssimulations are carried out by three techniques including Monte Carlo (MC), Molecular Dynamic (MD) andLangevin Dynamic (LD) simulations in aqueous solutions. Investigation the energy changes with t...

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 aquatic plants are a promising renewable energy resource. Lake Fúquene polluting macrophytes, water hyacinth (Eichhornia crassipes C. Mart.) and Brazilian elodea (Egeria densa Planch.), were saccharifiedby different treatments and fermented to ethanol by native yeasts. Among the tested chemical and biological methods for the saccharification, Pleurotus ostreatus at 10% (m/v) was chosen as t...

In this study, the bioactive compounds of loquat fruit (Eriobotrya japonica Lindl.) skin and pulp extracted by two extraction methods (solvent and ultrasound-assisted) with three solvents (ethanol, water and ethanol-water) were compared to supercritical fluid extraction. The antioxidant activities of skin and pulp extracts were evaluated and compared to tertiary butylhydroquinone (TBHQ) using 2...

Felicia muricata is a medicinal plant used for the management of different human and livestock diseases in the Eastern Cape Province of South Africa. The antioxidant potential of the leaves from this herb was investigated using its water, methanol, acetone and ethanol extracts. All the extracts were rich in phenols, proanthocyanidins and flavonols but low in flavonoids. The water extract exhibi...
