The antioxidant activity of Chuju polysaccharide and its effects on the viscera of diabetic mice

Abstract

Chuju polysaccharide, which is extracted from a traditional Chinese flower, contains diabetes benefits. In this study, the free radical scavenging ability and reducing force of the Chuju polysaccharides were determined. The Chuju polysaccharides were given intragastrically to the diabetic mice. Results have shown that three Chuju polysaccharides had certain scavenging effects on DPPH radical, hydroxyl radical and superoxide anion radical, which are stronger than VE, but weaker than VC. The scavenging effects of three Chuju polysaccharides on hydroxyl radical were as follows: D2 > D1 > D3. The reducing force of the three components was also shown as the same, indicating that Chuju polysaccharide had strong antioxidant activity. According to the histological anatomy and pathological section analysis of mice, the three components of Chuju polysaccharide could have a certain protective effect on liver, kidney and pancreas. The components with stronger antioxidant activity contain a more significant protective effect. Together, these findings indicated that Chuju polysaccharides possess great potential as a diet supplement or medication for diabetes.
