Carbohydrates and ginsenosides in ginseng are biol. interrelated. Their synchronous anal. is therefore essential in chem. research on ginseng to characterize its “holistic” quality. Here we investigated the processing chem. of red ginseng (RG), a ginseng product processed by water-steaming, for which both carbohydrates and ginsenosides were qual. and quant. determined through multiple anal. techniques. Results revealed that the steam-processing not only qual. and quant. altered the ginsenosides but also affected the polymeric carbohydrates via changing their physiochem. parameters, i.e. water-solubility, mol. size, types and ratios of constituent monosaccharides. Potential mechanisms involved in the transformation of ginseng chems. are proposed and discussed, including hydrolysis (deglycosylation, demalonylation, deacetylation), dehydration, polymerization, volatilization, reduction and the Maillard reaction. The study strengthens the research on the processing chem. of RG, and therefore should be helpful for elucidating the scientific basis of RG preparation and application. In the experiment, the researchers used many compounds, for example, (2R,3R,4S,5S)-2,3,4,5-tetrahydroxyhexanal hydrate (cas: 10030-85-0COA of Formula: C6H14O6).
(2R,3R,4S,5S)-2,3,4,5-tetrahydroxyhexanal hydrate (cas: 10030-85-0) belongs to alcohols. Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.COA of Formula: C6H14O6
