Pectin extracted from the apple pomace was evaluated for the in vitro inhibition of pancreatic lipase (steapsin). Pectin was extracted from two different varieties of apples, i.e., Malus pumila and Spondias dulcis using two extractants, i.e., hydrochloric acid and citric acid (CA), separately at pH 2.5.

plant biomass harvested after heavy-metal phytoremediation must be considered as a hazardous waste that should be contained or treated appropriately before disposal or reuse. this study provides an evaluation of extractants for the removal of lead from abutilon theophrastus biomass. the research was carried out a leaching study to determine the lead-extraction efficiency of the different leacha...

in this research, several chemical extractants and modified olsen methods were studied in 25 surface-calcareous soils (0-30 cm) for determining available phosphorus (p) for corn (zea mays l.) plant. in this experiment, the highest correlation was obtained between extracted p by olsen and colwell methods (nahco3-extractable p) and dry weight of corn shoot (r =0.67 and 0.75, p

Background: In nuclear technology, the solvent extraction is an important step for recovery of rare earth materials, purification, radionuclide production, and preparation of nuclear reactor materials. Tributyl phosphate (TBP) and toluene are taken as extractant and diluent, respectively, for study of extraction efficiency for rare earth element like CeO2. Methods: In the present paper, idea of...

The present work describes the results of research a complex substances obtained from sedimentary wine yeast by extraction with food extractants use ultrasound. filtrates alcoholic extracts and sediments isolated filtrate were investigated. It has been shown that hydrophobic moderately soluble poorly in alcohol, such as ethyl esters fatty acids, phospholipids, sterols, squalene, alcohol-contain...
