Co-cultured <i>Lepista sordida</i> and <i>Pholiota nameko</i> polysaccharide-iron(<scp>iii</scp>) chelates exhibit good antioxidant activity

Abstract

H NMR spectroscopy. The results suggested that polysaccharides were chelated with iron(iii) by -OH and -COOH groups, forming a stable structure of β-FeOOH and improving crystallinity. Furthermore, the antioxidant activities of polysaccharide-iron(iii) chelates exhibited stronger hydroxyl radical and superoxide radical scavenging activity than the polysaccharides. Therefore, the polysaccharide-iron(iii) chelates could be used as a potential iron supplement.
