Structural analysis and biological activity of cell wall polysaccharides extracted from Panax ginseng marc
2019, International Journal of Biological MacromoleculesAnalysis of pectin from Panax ginseng flower buds and their binding activities to galectin-3
2019, International Journal of Biological MacromoleculesCitation Excerpt :Due to the covalently linkage of RG-II, the content of GalA in HG fractions of ginseng flower buds was lower than that in ginseng roots, and the DM for these fractions was from 20.0% to 40.0%. Although pectin from ginseng leaves has not been characterized comprehensively like that from roots and flower buds, it also comprises of HG, RG-I, and RG-II domains with RG-II more abundant in leaves [35–37]. Different compositions and structures of polysaccharides in distinct organs of ginseng might be related to their various physiological functions in the plant.
Structural characterization of rhamnogalacturonan domains from Panax ginseng C. A. Meyer
2019, Carbohydrate PolymersCitation Excerpt :Therefore, ginseng RG-I domain is composed of both low-branched region with short side chains and high-branched region with long and various side chains. Several RG-II domains (GL-4IIb2, GL-RI, GL-RII and GL-RIII) had been extracted from ginseng leaves and structurally analyzed (Shin, Kiyohara, Matsumoto, & Yamada, 1997). However, there is no study concerning RG-II domains from ginseng roots.
Molecular mechanisms of immunomodulatory activity by polysaccharide isolated from the peels of Citrus unshiu
2018, International Journal of Biological MacromoleculesImmunoadjuvant activity in mice of polysaccharides isolated from the leaves of Panax ginseng C.A. Meyer
2018, International Journal of Biological MacromoleculesCitation Excerpt :Our previous study indicated that the polysaccharides isolated from P. ginseng comprised 15 kinds of monosaccharides, including rhamnose, fucose, arabinose, xylose, apiose (Api), mannose, galactose, glucose, 2-methylfucose (2MeFuc), 2-methylxylose (2-MeXyl), aceric acid (AceA), 2-keto-3-deoxy-d-manno-2-octulosonic acid (Dha), 2-keto-3-deoxy-d-lyxo-2-heptulosaric acid (Kdo), galacturonic acid, and glucuronic acid. Among these are six unusual sugars, namely 2-MeFuc, 2-MeXyl, Api, AceA, Kdo, and Dha, which have been identified as components of rhamnogalacturonan (RG)-II-containing polysaccharides of pectic substance isolated from plant cell walls [14–16]. Some studies already reported that biological activity of pectic substances resulted from rhamnogalacturonan−I and −II regions, not homogalacturonan, a linear chain of 1,4-linked α-d-galacturonic acid residues [17,18].
