Chemical and biological properties of an arabinogalactan from Phyllanthus niruri
Phyllanthus niruri is a well-known herb widely used medicinally in Asia, Africa, and South America. Aqueous extraction of the intact plant provided an acidic arabinogalactan, which was characterized
Lentinus edodes heterogalactan: Antinociceptive and anti-inflammatory effects
Abstract Cold aqueous extraction of basidiocarps (fruiting bodies) of the edible mushroom Lentinus edodes ( shiitake ) gave rise to a heteropolysaccharide, whose chemical structure, antinociceptive
Biomass and exopolysaccharide production in submerged cultures of Pleurotus ostreatoroseus Sing. and Pleurotus ostreatus “florida” (Jack.: Fr.) Kummer
Two Brazilian autochthonous strains of edible Pleurotus (P. ostratoroseus Sing. and P. ostreatus “florida”) were used to cultivate those microorganisms in the POL culture medium and the optimal growth time for EPS production was found to be 9‐day.
Anti-inflammatory and analgesic properties in a rodent model of a (1-->3),(1-->6)-linked beta-glucan isolated from Pleurotus pulmonarius.
Data showed that the glucan had potent anti-inflammatory and analgesic (antinociceptive) activities, possibly by the inhibition of pro-inflammatory cytokines.
Chemical and biological properties of a highly branched β-glucan from edible mushroom Pleurotus sajor-caju.
The results suggest that the ( 1→3), (1→6)-linked β-glucan from P. sajor-caju may have potential for immunological activities, although additional experiments are necessary for a better understanding of the mechanisms involved.
Structural characterization of a polysaccharide and a beta-glucan isolated from the edible mushroom Flammulina velutipes.
Two polysaccharides were isolated from the basidiomycete Flammulina velutipes, via successive hot extraction with water, 2% and 25% aq. KOH, and then submitted to freeze-drying. The precipitate
A 3-O-methylated mannogalactan from Pleurotus pulmonarius: structure and antinociceptive effect.
A mannogalactan was tested for its effects on the acetic acid-induced writhing reaction in mice, a typical model for inflammatory pain, causing a marked and dose-dependent inhibition of the nociceptive response, and an inflammatory response was not inhibited.
Structure of Agaricus spp. fucogalactans and their anti-inflammatory and antinociceptive properties.
The small differences in chemical structure in these polysaccharides thus modified their biological activities and were related to the anti-inflammatory effect.
A fungus-type beta-galactofuranan in the cultivated Trebouxia photobiont of the lichen Ramalina gracilis.
A structural characterization of polysaccharides extracted from the aposymbiotically cultured photobiont of the lichen Ramalina gracilis was carried out in order to compare them with those previously found in the symbiotic thallus, finding the galactofuranan has similarities with those found in some fungal cell walls.
Structure of two glucans and a galactofuranomannan from the lichen Umbilicaria mammulata
The three main polysaccharides from the lichenized fungus Umbilicaria mammulata were isolated and characterized. Their structures were determined using GC-MS of derived alditol acetates,
