However, the specific polysaccharide components exerting these effects are unclear. In this study, we extracted, separated, purified, and characterized the P. alkekengi polysaccharides Phy-1a, Phy-1b, and Phy-1c. Ion chromatography showed that Phy-1b was mainly composed of rhamnose, arabinose, galactose, glucose, and xylose at a molar ratio of 3.0:19.8:47.5:20.9:8.8, and Phy-1c was composed of rhamnose, arabinose, galactose, glucose, xylose, mannose, ribose Galactosamine hydrochloride and Glucosamine hydrochloride at a molar ratio of 10.4:7.9:22.8:30.5:4.6:4.4:19.4:3.9:5.8. Neither of these polysaccharides contained uronic acid, indicating their neutral property. Methylation analysis and nuclear magnetic resonance spectroscopy showed that Phy-1b was mainly composed of terminal sugars (1-Araf); 1,5-Araf; 1,4-Xylp; 1-Glcp; 2,4-Rhap; 1,3-Glcp; 1,4-Galp; 1,4-Glcp; 1,3-Galp; 1,6-Glcp; 1,3,6-Glcp; and 1,4,6-Galp at a molar ratio of 5.2:7.1:7.8:13.7:6.3:11.2:7.0:16.3:7.4:6.0:6.8:5.3, with the main chain being \u21922)-\u03b1-L-Rhap-(1\u21924)-\u03b2-d-Galp-(1\u21924)-\u03b2-d-Galp-(1\u2192[3)-\u03b2-d-Glcp-(1]2\u21923)-\u03b2-d-Glcp-(1\u2192[4)-\u03b2-d-Glcp-(1]2\u2192 and the branched chains being \u03b2-L-Araf-(1\u21925)-\u03b2-L-Araf-(1\u2192, \u03b2-d-Glcp-(1\u21924)-\u03b2-d-Xylp-(1\u2192 3)-\u03b2-d-Galp-(1\u2192, and \u03b2-d-Glcp-(1\u21926)-\u03b2-d-Glcp-(1\u2192. The three fragments, respectively, pass through the O-4 key of \u21922,4)-\u03b1-l-Rhap-(1\u2192, O-6 key of \u21924,6)-\u03b2-d-Galp-(1\u2192, and O-6 of \u21923,6)-\u03b2-d-Glcp-(1\u2192 connected to the main chain.
