Abstract In the manuscript, water-soluble polysaccharides WPNI was extracted from notopterygium incisum roots and separated into two homogeneous fractions WPNI-A-a and WPNI-A-b. WPNI-A-a was an arabinogalactan (AG). WPNI-A-b belonged to HG type pectin. The structure of WPNI-A-b was analyzed by FT-IR, NMR, enzymatic hydrolysis (Endo-PG) and UPLC-FLD-MSn. WPNI-A-b was dominated by HG domain, covalently linked with AG and RG-II domains. Oligogalacturonides produced by Endo-PG from HG domain were no...

Abstract Panax notoginseng is a widely used traditional Chinese medicine and has extensive pharmacological effects. In this work, water-soluble polysaccharides from Panax notoginseng were isolated and fractionated. One starch-like polysaccharide (PNPN) and six pectin fractions (PNPA-1A, PNPA-1B, PNPA-2A, PNPA-2B, PNPA-3A and PNPA-3B) were obtained. Monosaccharide composition, enzymatic hydrolysis, nuclear magnetic resonance and methylation analysis were combined to characterize their structures....
