Zhu, Jiangxiong published the artcileComparative analysis of existence form for selenium and structural characteristics in artificial selenium-enriched and synthetic selenized green tea polysaccharides, Name: (2R,3S,4S,5R)-2,3,4,5,6-Pentahydroxyhexanal, the main research area is artificial selenium enriched green tea polysaccharide; Artificial selenium-enriched tea polysaccharides; Structure characteristics; The form with selenium.
This study aimed to investigate the activity, structural characterization and present forms of selenium in two different artificial selenium-enriched tea polysaccharides (Se-TPS). The physicochem. anal. showed that both CSe-tps1 and ASe-tps1 were acidic heteropolysaccharides with different monosaccharide composition, molar ratio, and selenium content. Structural investigations including FT-IR, Raman spectra and 1D, 2D NMR anal. revealed that selenium in CSe-tps1 replaced the hydroxyl group at the C-6 position in the polysaccharide with the form of selenyl ester, while most of the selenium in ASe-tps1 replaced the hydroxyl group at the C-1 and C-6 position in the form of the Se-H bond on the branch of the polysaccharide. Besides, a series of studies on the structural characteristics of the Congo red test, I2-KI reaction, FESEM, DSC, and XRD anal. showed that the two artificial Se-TPSs had a triple helix structure and more branches. However, there were significant differences in crystal morphol., apparent morphol., heat release ability, and the α-glucosidase inhibition activity. These results indicated that the difference in artificial selenization methods not only made the polysaccharide exhibit different structural characteristics and the hypoglycemic activity, but also had a significant effect on the form of selenium in polysaccharides.
