Purification, characterization and antioxidant activities in vitro and in vivo of the polysaccharides from Boletus edulis bull



Purification, characterization and antioxidant activities in vitro and in vivo of the polysaccharides from Boletus edulis bull



Molecules 17(7): 8079-8090



A water-soluble polysaccharide (BEBP) was extracted from Boletus edulis Bull using hot water extraction followed by ethanol precipitation. The polysaccharide BEBP was further purified by chromatography on a DEAE-cellulose column, giving three major polysaccharide fractions termed BEBP-1, BEBP-2 and BEBP-3. In the next experiment, the average molecular weight (Mw), IR and monosaccharide compositional analysis of the three polysaccharide fractions were determined. The evaluation of antioxidant activities both in vitro and in vivo suggested that BEBP-3 had good potential antioxidant activity, and should be explored as a novel potential antioxidant.
