Hyaluronidase Inhibitory Activity of Polysaccharides Separated from a Fermented Beverage of Plant Extracts

Super Ohtaka®, a fermented beverage of plant extracts, is prepared from approximately 50 kinds of vegetables and fruits is a naturally fermented mainly by lactic acid bacteria (Leuconostoc spp.) and yeast (Zygosaccharomyces spp.). In this study, we separated water-soluble polysaccharides from Super Ohtaka® using dialysis and chromatography, yielding four polysaccharide fractions. The polysaccharide fraction designated as OEP3 exhibited hyaluronidase inhibitory activity. The half-maximal inhibitory concentration was 860 µg/mL. This polysaccharide not only stimulated macrophages but also inhibited hyaluronidase activity and showed weak 1,1-diphenyl-2-picrylhydrazyl radical-scavenging activity.
