This study was conducted to access the extraction yield of antioxidant and their activity from Egyptian tomato waste. Conventional and novel assisted extraction methods (ultrasound and microwave) usin...
The culture media prepared from mashed cassava and cassava starch were used to test their convertibility into organic solvents such as acetone, butanol, and ethanol. The trials were conducted in Erlen...
The effects of highly volatile organochlorine solvents (1,1,1-trichloroethane, TCET; trichloroethylene, TCE; and tetrachloroethylene, PCE) on soil nitrogen cycle and microbial counts were investigated...
The objective of this study was to develop a new method to separate phosvitin from egg yolk without using organic solvents. Phosvitin was extracted from yolk granules using 10% NaCl or 10% (NH4)2SO4 (...
We have developed a capillary chromatography system using an open capillary tube made of fused-silica, polyethylene, or poly(tetrafluoroethylene), and a water–hydrophilic–hydrophobic organic mixture c...
A new fluorescence dye, N-amino-4-(2-hydroxyethylamino)-1,8-naphthalimide (AHN), based on 4-bromo-1,8-naphthalic anhydride was synthesized as a fluorescence probe for determining water content in orga...
A tube radial distribution chromatography (TRDC) system was previously developed using an open capillary tube and an aqueous–organic solvent (water–acetonitrileethyl acetate) mixture as a carrier so...
The aim of this study was to evaluate the solubility of gutta-percha in four organic solvents used in endodontics. The solubility of gutta-percha (Dentsply) was assessed in xylol, orange oil, eucalypt...
The aim of this study was to investigate the e ect of acid and Alamine-336 concentrations, solvent types and mixing patterns on the extraction eciency of lactic acid from aqueous solutions with Alami...
Long chain aliphatic 1,2-diols like 1,2-hexanediol and 1,2-octanediol can be converted to the corresponding -hydroxy-alkanoates with total chemoselectivity, in an oxidation catalyzed by an aque...
Any given method for the analysis of semi-volatile total petroleum hydrocarbons (TPH, C10-C36) in contaminated soil is made up of a number of procedures, each of which may be subject to improvement o...
To stabilize the yield of fruit production in Vitis coignetiae Pulliat, which is a dioecious plant that requires pollination for fruiting, we investigated long-term pollen storage using organic solven...
Cytochrome P-450 Reductase enzyme is an important enzyme providing electrons to the microsomal cytochrome P-450 enzyme system metabolizing some endogenous subtances forming in the liver, drugs, chemic...
The extraction of chlorophyll a (Chla) with 90% acetone and 96% ethanol was compared in different Estonian stratified lakes and in polymictic Lake Võrtsjärv. The effect of the extraction r...
Prediction of Diffusion Coefficients of Liquid and Solid Solutes in Supercritical Solvents.
