Investigation of chemical and biological properties of an acidic polysaccharide fraction from Pleurotus eous (Berk.) Sacc.

Pleurotus eous, pink oyster mushroom and functional food, is widely cultivated in Southern India. In this study, we successfully attempted, to isolate a new acidic polysaccharide fraction (PEPA-1a) possessing a molecular weight of 8.926 × 104 Da from the fruiting bodies of Pleurotus eous through ion-exchange and gel-filtration chromatographic techniques. Monosaccharide composition comprising glucose, galactose, rhamnose, mannose, and N-acetyl...
