Abstract
The insoluble complexes formed by polyphenols from plant extracts and chitosan are of interest as potential delivery systems for polyphenols in the intestine. The complexes formed by polyphenols from an aqueous sage extract and chitosan have been investigated. These complexes have been shown to be stable in neutral media and to release polyphenols in highly acidic and highly alkaline environments. The complexes demonstrated significant polyphenol release in simulated intestinal fluid, with minimal release in simulated gastric and salivary fluids. It has been demonstrated that the complexes formed with chitosan are primarily composed of flavonoid glycosides and phenolic acids, with flavonoid aglycones present in trace amounts.
期刊介绍：
Applied Biochemistry and Microbiology is an international peer reviewed journal that publishes original articles on biochemistry and microbiology that have or may have practical applications. The studies include: enzymes and mechanisms of enzymatic reactions, biosynthesis of low and high molecular physiologically active compounds; the studies of their structure and properties; biogenesis and pathways of their regulation; metabolism of producers of biologically active compounds, biocatalysis in organic synthesis, applied genetics of microorganisms, applied enzymology; protein and metabolic engineering, biochemical bases of phytoimmunity, applied aspects of biochemical and immunochemical analysis; biodegradation of xenobiotics; biosensors; biomedical research (without clinical studies). Along with experimental works, the journal publishes descriptions of novel research techniques and reviews on selected topics.
