dc.description.abstractPleurotus citrinopileatus, popularly known as golden oyster mushroom have medicinal properties, which are attributed mainly to the presence of bioactive polysaccharides. In this work, two partially 3-O-methylated galactans were isolated from the fruiting bodies of this fungus, via successive aqueous extraction, followed by fractionation by freeze-thawing, and precipitation of soluble material with Fehling solution. The structural assignments were carried out using mono-and bidimensional NMR spectroscopy, monosaccharide composition, and methylation analyses. The polysaccharides were characterized as linear, partially 3-O-methylated (1 -> 6)-linked alpha-galactopyranans, containing only Gal and 3-O-Me-Gal, in 2:1 and 1:1 molar ratios, with molar masses of 37.6 x 10(3) g/mol and 28.5 x 10(3) g/mol, respectively. Similar structures have been described for other Pleurotus spp., but showing a lower content of 3-O-Me-Gal. (c) 2018 Elsevier Ltd. All rights reserved.en
