Liu, Yuntao published the artcileExtraction, structure characterization, carboxymethylation and antioxidant activity of acidic polysaccharides from Craterellus cornucopioides, Synthetic Route of 59-23-4, the main research area is acidic polysaccharide Craterellus extraction structure carboxymethylation antioxidant activity.
Herein, we isolated and purified polysaccharides from Craterellus cornucopioides. Chem. composition anal. revealed that both polysaccharides (CCPs-1 amd CCPs-2) were composed of different molar ratios of rhamnose, fucose, arabinose, xylose, mannose, glucose, and galactose. The structure of polysaccharides was determined using FT-IR, periodate oxidation, smith degradation, methylation anal., and NMR, which demonstrated that the two polysaccharides were primarily connected by mannose with (1â?)-linked. Notably, the configuration of the two polysaccharides exhibited random coil with pyranoid polysaccharide containing α or β glycosidic bond. Furthermore, to increase the antioxidant activity of polysaccharides (CCPs-1 amd CCPs-2), two carboxymethylated polysaccharides were obtained as cmCCPs-1 and cmCCPs-2 with the degree of substitution values of 0.34 and 0.52, resp. Structural anal. elucidated that nonselective carboxymethylation occurred in cmCCPs-1 and cmCCPs-2, where C-2, C-4 or C-6 were partially substituted. Of note, cmCCPs-2 exhibited the most significant antioxidant activity.
Industrial Crops and Products published new progress about Antioxidants. 59-23-4 belongs to class alcohols-buliding-blocks, name is (2R,3S,4S,5R)-2,3,4,5,6-Pentahydroxyhexanal, and the molecular formula is C6H12O6, Synthetic Route of 59-23-4.
