Sparassis latifolia polysaccharides(SLPs)were modified by phosphorylation,and then characterized for structure,and analyzed for antioxidant and hypoglycemic activities in vitro.The results showed that compared with SLPs,phosphorylated SLPs(P-SLPs)had a higher mass fraction of phosphate ions,which was(8.02±0.48)%.Under the same mass concentration,P-SLPs showed higher abilities on scavenging DPPH radicals,superoxide anion radicals,hydroxyl radicals,and H2O2 than SLPs.The inhibitory activities of P-SLPs on a-amylase and a-glucosidase were also significantly promoted compared with SLPs.The research results provided a reference for further development and application of SLPs.
