title: Comparison of the preliminary characterizations and antioxidant properties of polysaccharides obtained from Phellinus baumii growth on different culture substrates.
abstract: Three polysaccharides (PPB-MB, PPB-MW and PPB-MM) were obtained from the fruiting body of Phellinus baumii growth on different culture substrates (mulberry branches, mixed wood sawdust and an equal combination of the two materials) and their chemical composition was investigated. PPB-MM contained the highest contents of neutral sugar (66.59%) and uronic acid (23.38%), followed by PPB-MW and PPB-MB, with PPB-MW having the highest protein content. The three polysaccharides were all composed of six kinds of monosaccharides, namely fucose, mannose, glactose, xylose, arabinose and glucose. The antioxidant activities of the three polysaccharides were determined using lipid peroxidant inhibition, ABTS radical scavenging, and Fe(2+)-chelating assay. Results showed that PPB-MM exhibited the highest antioxidant properties in all the assays. As a result, an equal combination of mulberry branches and mixed wood sawdust serves as a good culture substrate for producing such antioxidant polysaccharides.
