| Abstract | In this work, two kinds of phenolic antioxidants-functionalized quaternized chitosan were synthesized in order to develop aqueous soluble antioxidant–polymer conjugates. Quaternized chitosan conjugated with gallic acid or caffeic acid was carried out and the antioxidant properties of the products (namely gallic acid-quaternized chitosan and caffeic acid-quaternized chitosan) against hydroxyl-radical, superoxideeywords: uaternized chitosan ntioxidant ntioxidant–polymer conjugates radical and DPPH-radical were evaluated in vitro, respectively. The scavenging activities of the obtained gallic acid-quaternized chitosan and caffeic acid-quaternized chitosan exhibit a remarkable improvement over those of either chitosan or quaternized chitosan. And the scavenging effect indices of the products were all higher than 90% at a concentration of 1000 g/mL. Because gallic acid-quaternized chitosan and caffeic acid-quaternized chitosan are convenient to prepare and possess improved potential activities, esent these materials may repr |
