Chemical characteristics of a heteropolysaccharide from Tylopilus ballouii mushroom and its antioxidant and anti-inflammatory activities.

Fucogalactomannan (FGM) is a non-sulphated polysaccharide isolated from the Tylopilus ballouii mushroom. We investigated the chemical characteristics of this FGM using HPLC, chemical methods, and NMR studies ((1)H, (13)C, (1)H/(13)C-HSQC and DEPT-135 spectroscopies) without chemical fragmentation. This polysaccharide consisted primarily of mannose and galactose with variable amounts of fucose and traces of xylose and with MW of 140kDa.

Antioxidant and Anti-Inflammatory Properties of an Extract Rich in Polysaccharides of the Mushroom Polyporus dermoporus.

Polyporus dermoporus mushroom, native to Brazil, is produced under natural conditions in the unexplored reserve of Mata da Estrela-Rio Grande do Norte-RN. These mushrooms were delipidated with chloroform:methanol (2:1 v/v), extracted with water at 100 °C, and fractionated with ethanol (one and three volumes) and then centrifuged. The ethanol precipitation showed a high total sugar level of 64.
