Polysaccharides from Tetrastigma hemsleyanum Diels et Gilg: Extraction optimization, structural characterizations, antioxidant and antihyperlipidemic activities in hyperlipidemic mice

International Journal of Biological Macromolecules, 2019
In this study, a novel polysaccharide TDGP-3 from Tetrastigma hemsleyanum Diels et Gilg was extracted by enzymolysis-ultrasonic assisted extraction (EUAE) method and its antioxidant and hypolipidemic activities were evaluated. With a molecular weight of 3.31 × 105 Da, TDGP-3 was composed of 1,4-Glcp, 1,4-Glap and 1,3,6-Manp linkage in the main chain ...
