Migration of chemicals from plastic containers into drinks and liquids containing them, is supposed to be a hazardous phenomenon and results in many health problems. Sample preparation is of great importance due to trace amounts analysis of these compounds. In this research, dispersive liquid–liquid microextraction is applied for the extraction and preconcentration of the migrated compounds pri...

( ) Affinity-based re®ersed micellar extraction and separation ARMES has pro®en effecti®e in separating glycoproteins from nonglycosylated proteins from natural sources. The ability of ARMES to resol®e closely related glycoproteins is of paramount importance if ARMES is to be used in glycoform resolution. It is demonstrated that ARMES ( ) can resol®e the structurally similar soybean peroxidase ...

Soybean (Glycine max (L.) Merr.) has emerged as one of the most economical and nutritious foods. Kunitz Soybean Trypsin Inhibitor (KSTI) and Bowman -Birk Inhibitor (BBI) are the two major trypsin inhibitors in soybeans. The ingested soybean trypsin inhibitors cause growth depression as demonstrated in different animal species and human. The main part of the present study was devoted to isolatio...

A simplified and efficient method is developed for the large-scale purification of the secoisolariciresinol diglucoside (SDG) from defatted flaxseed after aqueous ethanol extraction. Extractant from defatted flaxseed with aqueous ethanol is hydrolyzed with basic solution, concentrated under vacuum, subjected to Sephadex LH-20 column chromatography, and eluted with aqueous ethanol of different c...

Chromatographic techniques have led to considerable development in mixture ingredient analysis. With the development of stationary-phase and high-pressure module technologies, new possibilities have emerged for the separation of complex systems whose components are characterised by similar structures and properties. Modern detection systems now allow detection and identification of individual i...
