Mutaillifu, Paiheerding published the artcileStructural characterization and antioxidant activities of a water soluble polysaccharide isolated from Glycyrrhiza glabra, Related Products of alcohols-buliding-blocks, the main research area is Glycyrrhiza GPN polysaccharide antioxidant activity glycosidic bond water solubility; 1,4-Linked α-D-Glcp; Antioxidant activity; Glycyrrhiza glabra; Water soluble polysaccharide.
A water-soluble polysaccharide, named GPN, with mol. mass 38.7 kDa was isolated from Glycyrrhiza glabra with hot water extraction, ethanol precipitation, and purified by column chromatog. Monosaccharide composition anal. confirmed the presence of predominant glucose (98.03%) and trace amount of mannose, arabinose, and galactose. Methylation and GC-MS anal. revealed that the main glycosidic bonds in GPN comprised 1,4-linked Glcp, T-linked Glcp, 1,4,6-linked Glcp, and 1,6-linked Glcp. Based on these results and 1D/2D NMR spectroscopy, GPN has a linear backbone of 1,4-linked α-D-Glcp and 1,6-linked α-D-Glcp which substituted at C-4 of glucose. The side chain probably composed from 1,4-linked to main side α-D-Glcp and terminal 1-linked β-D-Glcp to the C-3 of D residue. Congo red assay confirmed the existence of triple helix structure. Moreover, SEM and XRD anal. revealed that the GPN had irregular fibrous, filaments like surface; and both crystalline and amorphous structure. GPN also displayed favorable thermal stability. Moreover, G.glabra polysaccharide showed good antioxidant activity.
