Description

In previous research, some G. glabra polysaccharides were isolated and examined its physicochemical property and preliminary structural features. However, the detailed structure of G. glabra polysaccharides and its conformational structural properties have not been studied systematically. Therefore, the purpose of the present study was to systematically investigate the fine structure and conformational properties and antioxidant activities of G. glabra polysaccharide by Ligand-Exchange HPLC column, methylation and GC-MS analysis, one and two-dimensional NMR spectra and Congo red staining. Moreover, scanning electron microscope and X-Ray Diffraction analysis were used to confirm the shape of polysaccharide. Thermal properties of polysaccharide were also studied. Antioxidant activities of G. glabra crude polysaccharides were studied on the model of DPPH radical scavenging, ABTS radical scavenging, and hydroxyl radical scavenging rates.
