In this study, the water-extracted ethanol precipitation method was used to extract Polysaccharides in Pyropolyporus Formentarius (PFPS), and the capacities of scavenging DPPH and ABTS were analyzed. Different concentrations of PFPS were used to detect the resistant abilities against Escherichia coli, Staphylococcus aureus, and Bacillus subtilis, and Micrococcus tetragenus, and the relative minimum inhibitory concentration (MIC) were also determined. The results showed that PFPS could eliminate DPPH and ABTS. When the concentration of PFPS was 1.0 mg/mL, the ability of scavenging DPPH and ABTS exceeded that of the BHT control, while was weaker than the VC reference substance. …

In order to determine the change rule of polysaccharides content in fresh rice grains at different mature stages, the polysaccharides were extracted from fresh rice grains at different mature stages by ultrasonic-microwave synergistic extraction method. The composition of polysaccharides was analyzed by HPLC, and the antioxidant activity of polysaccharides was determined by antioxidant test in vitro. The results showed that the content of polysaccharides in fresh rice was the highest at the stage of late milk, up to 46.89 mg/g. Mannose, rhamnose, glucuronic acid, galacturonic acid, glucose, galactose, xylose, arabinose and fucose were the main components of polysaccharides at this …
