A Pectin Polysaccharide from <i>Arnebia szechenyi</i> Kanitz and Its Digestion Product: Physicochemical Properties and Immunostimulatory and Antioxidant Activities.

ABSTRACT: The root of Arnebia szechenyi Kanitz, known as "Mongolia Zicao," has been widely used in traditional Chinese and Mongolia medicine. Herein, we aimed to characterize a pectin polysaccharide extracted from A. szechenyi Kanitz root (ASP), elucidate its structure, and evaluate potential immunomodulatory activities through in vitro assays. Sugar composition analysis and high-performance gel permeation chromatography (HPGPC) revealed that ASP is predominantly composed of GalA (45.44%), Gal (22.13%), and Ara (19.86%) with a homogenous molecular weight of 18.4 kD. ASP was identified as a typical pectin-like polysaccharide containing linear HG domains and potentially linked to complex branches with Ara and Glu residues. The monosaccharide analysis of the digestion product, D-ASP, supp
