Nowadays, Inulin, due to its nutritional properties, is widely being used all over the world. Artichoke tuber is one of its major industrial extraction sources. Therefore, in the present study we initially aimed to determine total carbohydrate, inulin, reducing sugars as well as dry matter contents of an Iranian artichoke. Thereafter, we focused on the optimization of aqueous extraction of inul...
as 'thyroxine'. The methods have been reviewed by Harington (1933) and Salter (1940). On adapting the original butanol-extraction procedure of Leland & Foster (1932), as modified by Blau (1935), to artificially. iodinated proteins, Reineke, Turner, Kohler, Hoover & Beezley (1945) compared their results with those of biological assay in the guinea pig and were led to conclude that the chemical m...

a new carboxylic acid extractant, named 2-(dibutylcarbamoyl)benzoic acid, is prepared and its potential for selective solvent extraction and recovery of lead ions from industrial samples was investigated. the slope analysis indicated that the lead ions are extracted by formation of 1:2 metal to ligand complexes. the effect of the parameters influencing the extraction efficiency including kind o...
The effect of mechanical activation on the kinetics of ammoniacal thiosulfate leaching of a refractory oxide gold ore containing 2.8 ppm Au was investigated. The gold extraction of 99.81% was achieved by 16 h leaching of a sample mechanically activated for 60 minutes. The gold extraction observed for a similar reference sample without mechanical activation was only 55%. Studies revealed that le...
Background: The most important researches in molecular and genetic engineering fields are the finding of optimal methods for extraction of the genomic content of microorganisms and cells using them, can achieve the most amount and purity with the least time and cost. There are several methods for the extraction of bacterial DNA and the use of magnetic nanoparticles is one of the novel methods o...
The goal of this study was to investigate the most suitable kinetic models for pectin extraction by way of ultrasound-assisted extraction (UAE) and conventional heating extraction (CHE) with acid from melon peel. The ultrasound and acidic assisted extraction were performed on powdered melon peel in three different temperatures of 40-55-70°C and 50-70-90°C, respectively. It was observed that, in...
