Constituents actually responsible for the antioxidant activities of crude polysaccharides isolated from mushrooms

Extraction optimization and characterization of polysaccharide antioxidants from <i>Pinellia ternata</i> (Thunb) Breit rhizome

“…[15]. Polysaccharides extracted from natural materials have been reported to have significant antioxidant activities based on large amounts of antioxidant assays in vitro and in vivo [29]. The present study indicates that PRP has good antioxidant activities as shown by scavenging DPPH and scavenging superoxide anion radicals data.…”

Chemical properties and bioactivities of Goji (Lycium barbarum) polysaccharides extracted by different methods

“…Similarly, phenolic constituents have also been identified as the major contributors to the antioxidant activities of crude polysaccharides extracted from various medicinal mushrooms . In addition, the higher protein content of LBP-US may also contribute to its higher antioxidant activity than the other LBPs by the other extraction methods as shown in previous studies on the polysaccharides extracted from various edible and medicinal fungi (Cheung et al, 2012;Siu et al, 2014). Fig.…”

“…Antioxidant activities of LBPs were determined by three chemical assays, ferric reducing ability of plasma (FRAP), trolox equivalent antioxidant capacity (TEAC) for scavenging ABTS radicals, and DPPH radical scavenging assay as described previously (Lin et al, 2009;Siu et al, 2014). For all assays, the LBP samples were predissolved in DI water and tested at various concentrations against DI water as the blank and vitamin C (Vc) as an antioxidant reference.…”

Bioactivities and Health Benefits of Mushrooms Mainly from China

“…Purified polysaccharides free of phenolic compounds and protein had no significant activities. Thus, the phenolic and protein components instead of carbohydrates were mainly responsible for the antioxidant activities of mushroom polysaccharides [12]. In another study, crude polysaccharides isolated from four common edible mushrooms including Agaricus bisporus, Auricularia auricula, Flammulina velutipes and Lentinus edodes were studied.…”
