Preparation, analysis and properties of shaddock ped polysaccharide and its derivatives
Copyright © 2023 Elsevier Ltd. All rights reserved..
The shaddock ped polysaccharide (SPP) was extracted by ultrasound-assisted enzyme method. Phosphorylated shaddock ped polysaccharides (P-SPP) and acetylated shaddock ped polysaccharides (Ac-SPP) were obtained by chemical modification of SPP. The characterization methods such as infrared spectroscopy and nuclear magnetism were employed to characterize the structures of the two derivatives. The antioxidant activity of SPP and its derivatives was investigated by measuring their DPPH radical scavenging capacity, hydroxyl radical ion scavenging capacity and superoxide anion scavenging capacity. In comparison, P-SPP showed better antioxidant activity. The results indicated that the antioxidant activity of the polysaccharides varied with different chemical modifications.
