Extraction, structural characterization, and immunoregulatory effect of a polysaccharide fraction from Radix Aconiti Lateralis Preparata (Fuzi)

A water-soluble polysaccharide fraction named FZPS-1 was obtained from Radix Aconiti Lateralis Preparata (Fuzi in Chinese). Physicochemical and instrumental analyses indicated that the purified FZPS-1 with an average molecular weight of 6.29 × 106 Da was composed of D-arabinose and d-glucose with a molar ratio of 7.5:92.5. It would contain the main chain fragments of →4)-α-D-Glc-(1 → 4)-α-D-Glc-(1→, with the side chain of terminal α-L-Ara-(1 →...
