{Abstract}: Medicinal health benefits uses of edible as well as non-edible mushrooms have been long recognized. The pharmacological potential of mushrooms, especially antitumor, immunostimulatory and anti-inflammatory activities has been documented. Wild ectomycorrhizal mushroom, Lactarius rufus had the anti-inflammatory and antinociceptive potential of their polysaccharides evaluated using the formalin model. Two structurally different (13),(16)-linked -d-glucans were isolated from fruiting bodies. Soluble (FSHW) -d-glucan 1-30mgkg-1 produced potent inhibition of inflammatory pain caused by formalin when compared with the insoluble one (IHW), suggesting that solubility and/or branching degree could alter the activity of -glucans. Their structures were determined using mono- and bi-dimensional NMR spectroscopy, methylation analysis, and controlled Smith degradation. They were -d-glucans, with a main chain of (13)-linked Glcp residues, substituted at O-6 by single-unit Glcp side chains (IHW), on average to every fourth residue of the backbone, or by mono- and few oligosaccharide side chains for soluble -glucan.   2013 Elsevier Ltd.

{Abstract}: Tricholoma matsutake, a high-class edible mushroom in China, has been regarded as famous foods and biopharmaceutical materials with a great deal of interest. In the previous investigations, researchers believe the water-soluble polysaccharide -glucan is the major active component of T. matsutake, which displays various biological activities. In the present study, two novel alkali-extracted polysaccharide fractions, TM-APS-1 and TM-APS-2, were isolated from the fruit bodies of T. matsutake by DEAE-cellulose and Sepharose CL-6B columns on ATKA explorer chromatography system. Their chemical and physical characteristics and radical scavenging capacity were valuated, including chemical methods, GC, HPLC, scavenging activity against DPPH radicals, superoxide radicals, hydroxyl radicals, and chelating ability. The results showed that TM-APS-1 and TM-APS-2 exhibited significantly antioxidant activity at a concentration-dependent manner. The alkali-extracted polysaccharide fractions from T. matsutake can be developed to be novel functional food or pharmaceutical products with antioxidant effects.   2012 Springer Science+Business Media Dordrecht.

{Title}: Physiochemical properties and antitumor activities of two -glucans isolated from hot water and alkaline extracts of Cordyceps (Cs-HK1) fungal mycelia

{Abstract}: Two novel polysaccharides, WIPS and AIPS, were isolated and fractionated respectively from hot water and alkaline extracts of the mycelial biomass of a medicinal fungus Cordyceps sinensis (strain Cs-HK1). Through analytical and degradation experiments, WIPS and AIPS were characterized as -d-glucans with a backbone of (1   4)-linked -d-Glcp (60%) and very similar molecular weights (M w : WIPS 1180 kDa; AIPS 1150 kDa). WIPS had a short branch of (1   6)-linked -d-Glcp (14%), but AIPS was a linear glucan, distinctive from the branched structures of most glucans from medicinal fungi. In aqueous alkaline solutions, both AIPS and WIPS exhibited a random coil structure with the similar conformational parameters but significantly different polydispersity indexes, 0.19 versus 0.37. AIPS exhibited much more significant antitumor and immuno-stimulatory effects than WIPS in animal tests on melanoma tumor-bearing mice.   2011 Elsevier Ltd. All rights reserved.
