The rice bran polysaccharide was extracted from defatted rice bran, and the optimal conditions of the experiment were determined. The chemical structure of rice bran polysaccharide was analyzed by IR and 13 C NMR. Three rice bran polysaccharide derivatives were prepared and characterized, namely carboxymethylated rice bran polysaccharide, phosphorylated rice bran polysaccharide, and acetylated rice bran polysaccharide. It showed that the phosphorylated rice bran polysaccharide had good activity.

“…Firstly, 0.8 g PPSP (Huang et al., 2021) was dissolved in 20 ml DMF and stirred in a closed container at room temperature for about 4 hr to set aside. 15 ml pyridine solution was dropped into a 250 ml three‐necked flask and precooled by stirring in an ice‐water bath for 30 min.…”

“…Phosphorylated polysaccharide, as important derivatives of polysaccharide, is one of the indispensable ways to study the structure-activity relationship of polysaccharides, which is of great significance for the research and development of polysaccharide drugs (Benchamas et al, 2021;Mu et al, 2021;Yang & Huang, 2021;Yang et al, 2021;Zhou et al, 2021). Phosphorylated polysaccharide exists widely in nature and their structures are complex and diverse.…”

Purple sweet potato polysaccharide was extracted via hot water, and it was chemically modified by phosphorus oxychloride-pyridine to obtain phosphorylated polysaccharide from purple sweet potato (P-PPSP) with certain degrees of substitution. Furthermore, the structure and antioxidant activity in vitro of PPSP and phosphorylated derivative were compared. The result indicated that the phosphorylation modification product of polysaccharide from purple sweet potato could improve the scavenging effect on hydroxyl radical and superoxide anion of PPSP, significantly. It also could improve the anti-lipid peroxidation ability while fail to improve the reducing ability of PPSP.
