Extraction, structural characterization, and physicochemical properties of polysaccharide from purple sweet potato

Chem Biol Drug Des. 2021 Dec;98(6):979-985. doi: 10.1111/cbdd.13952. Epub 2021 Sep 26.

Abstract

The polysaccharide from purple sweet potato (PPSP) was extracted. The structure was characterized and partial physicochemical properties were described of PPSP via UV, IR, NMR, XRD, DSC-TGA, LDS, and Congo red assay. This study provided a theoretical basis for the in-depth structural analysis of PPSP and the study of its biological activity.

Keywords: characterization; extraction; polysaccharide; properties.
