The photochemistry of Fe(III) coordinated to natural uronate-containing polysaccharides has been investigated quantitatively in aqueous solution. It is demonstrated that the photoreduction of the coordinated Fe(III) to Fe(II) and oxidative decarboxylation occurs in a variety of uronate-containing polysaccharides. The...

Lycium barbarum polysaccharide (LBP), is a major active ingredient Lycium barbarum (LB), which exhibits several beneficial effects through NF-κB, PI3K-Akt-mTOR, p38-MAPK, Wnt-β-catenin, PI3K-Akt-GSK-3β, and MyD88 signal pathway, including anti-oxidation, and anti-aging, hypolipidemic and hypoglycemic, radiation, anti-tumor, and neuroprotection. Today,...

Gentiana straminea Maxim. exhibits various biological activities. However, the purification and functions of polysaccharides in Gentiana straminea Maxim. have never been reported. Herein, by proposing a flexible 3D graphene-based decoloration column (3DD column), Gentiana straminea Maxim. polysaccharide (GMP) was...
