摘要

In the present study, the structural characteristics and antioxidant activities of polysaccharide from the co-culturedLepista sordidaandPholiota namekoand its polysaccharide-iron(iii) chelates were determined. Two polysaccharide fractions named CP-1 and CP-3 were isolated previously from polysaccharide of the fermentation liquid of the co-culturedLepista sordidaandPholiota nameko. And their chemical structures were measured by FT-IR infrared spectroscopy, TG analysis, X-ray diffraction and(1)H NMR spectroscopy. The results suggested that polysaccharides were chelated with iron(iii) by -OH and -COOH groups, forming a stable structure of beta-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.
