Guo, M.-Z. published the artcileStructure characterization, physicochemical property and immunomodulatory activity on RAW264.7 cells of a novel triple-helix polysaccharide from Craterellus cornucopioides, Synthetic Route of 59-23-4, the main research area is Craterellus macrophage immunomodulation polysaccharide; Chemical structure; Craterellus cornucopioides; Polysaccharide; Stability immunomodulatory activity.
In the study, a new triple-helix polysaccharide with favorable stability was purified from C. cornucopioides. Its structural characterization, stability and solution behavior were investigated by the GC-MS, periodate oxidation-smith degradation, FT-IR, 1D and 2D NMR spectroscopy, methylation anal., Scanning electron microscope, Congo-red, CD, TGA and DSC anal. The results showed that Craterellus cornucopioide polysaccharide (CCP) possessed the mol. weight of 1.97 × 103 kDa, is mainly composed of mannose (48.73%), galactose (17.37%), glucose (15.97%) and xylose (17.93%), resp. It was a heteroglycan with (1 → 3)-linked-β-D-Manp-(1 → 6)-linked a-D-Galp backbone distributed by (1 → 4)-linked-a-D-Xylp-t-a-D-Manp and t-β-D-Glup units at O-6. The result of TGA and DSC assay indicated that CCP has a favorable thermal stability. MTT and Scanning electro microscopy (SEM) assay showed that CCP could significantly improve the proliferation activity and induce cells activation of RAW264.7 in a certain range of concentrations and period.
