Beschreibungen/Notizen

• Conjugates of chitosan (molecular weight 28 and 830 kDa) with gallic acid were synthesized by a reaction initiated by a free radical. The conjugates contained 106 and 119 mg of polyphenol per g of polymer. Thin films were obtained from solutions of synthesized chitosan derivatives, and their physico-chemical characteristics (thickness of 0.058–0.076 mm and moisture content of 7.92–9.44%), as well as the antioxidant (inhibiting activity with respect to 2,2-diphenyl-1-picrylhydrazyl) and antimicrobial properties, were studied in relation to Staphylococcus epidermidis and Escherichia coli .
