Objective:To investigate the antioxidant effect in vitro of polysaccharides in Sophora alopecuroides(SAP) and its derivatives.Method: After sulfation and phosphorylation of the SAP
the scavenging capacities of 1
1-diphenyl-2-picrylhydrazyl
superoxide anion radicals
hydroxyl free radicals and reducing power were assayed
with vitamin C(VC) as control.Result: The activity of modification products was increased with the concentration increasing.The scavenging rate against 1
4.573 mg·L-1) and superoxide anion radicals IC50 2.651 mg·L-1 of SAPS were more than SAP.The scavenging rate against DPPH IC50
6.542 mg·L-1 and hydroxyl free radicals IC50 4.368 mg·L-1 of SAPP were more than SAP.Conclusion: The antioxidant activity of polysaccharides in S.alopecuroides can be improved through sulfation and phosphorylation of the SAP.
