Hot water extract (LN), partially purified polysaccharides (LP) and hot alkali extracted polysaccharides (LNa) obtained from fruiting bodies of the wild basidiomycete Laetiporus sulphureus were examined for their antioxidant activities. LNa was the most active antioxidant, as shown by the median effective concentrations (EC50 values) of 1,1-diphenyl-2-picrylhydrazyl (DPPH) scavenging activity (0.5 +/- 0.2 mg/ml), reducing power (4.0 +/- 0.3 mg/ml) and ferrous ion-chelating ability (1.5 +/- 0.1 mg/ml). LNa contained the highest level of alpha-glucan (17.3 +/- 1.2 g/100 g dw), whereas LP contained mostly beta-glucans (66.8 +/- 1.3 g/100 g dw). The prevalent monosaccharide in all extracts was glucose. The EC50 values of all three antioxidant activity assays were well-correlated with the alpha-glucan content. Strong and significant correlation was found between total phenolic compounds and DPPH scavenging ability and also reducing power. The three investigated extracts (at concentrations o...f 0.1-10 mg/ml) were not toxic to HTR-8/SVneo trophoblast cell line.
