Abstract:
In the study, the structural features and hypoglycemic effects of a polysaccharide Pan from the root of Panax notoginseng were investigated. The molecular weight of Pan was 8.27 kDa. Structural analysis indicated that Pan mainly consisted of →3)-β-L-Rhap-(1→, →3,6)-β-D-Galf-(1→ and →6)-β-D-Galf-(1→ residues with acetyl groups. Pan exhibited good antioxidant activity. Pan could slow down the body weight and the content of blood glucose in the high-fat diet-induced mice, further suppress GLUT-2 and SGLT-1 expression in the intestines, and enhance p-IRS and p-AMPK expression in the livers, finally exhibiting hypoglycemic effects. The results could supply a direction for further research on polysaccharides as components for the control of hyperglycemia induced by obesity and diabetes.
