Structural characterization and mechanisms of anti-diabetic activity of a novel polysaccharide with a fructose backbone from Polygonatum cyrtonema Hua.
In this study, a novel homogeneous polysaccharide (PCP-J-1, 7.384 kDa) with a fructose backbone was isolated from the roots of Polygonatum cyrtonema Hua (PCH). Structural analysis revealed that its main chain consists of →1)-β-D-fructofuranosyl-(2 → and →1,6)-β-D-fructofuranosyl-(2 → residues, with side chains of β-D-f...
