Chardonnay marc (pomace), an agricultural waste product, has demonstrated significant potential health benefits in previous studies. This study represents the first comprehensive chem. characterization of chardonnay marc, its seed and seedless fractions, and a seed extract to uncover the bioactive compounds inducing their observed health benefits. Chardonnay marc and its processing fractions’ gross composition (i.e. protein, lignin, fat, carbohydrates, polysaccharides), phenolic contents, and oligosaccharide profiles were determined The chardonnay seeds contained higher quantities of protein, fat, and polysaccharides than the seedless marc while the seedless marc contained more total carbohydrates and sugars. All samples had abundant phenolics with the seed extract being the most concentrated (34.72 ± 0.13 mg/g). (-)-Gallocatechin was the most abundant phenolic in the marc (1.4905 ± 0.0393 mg/g) and seedless marc (0.94 ± 0.04 mg/g), and (-)-epicatechin was the most concentrated phenolic in the seeds (9.4093 ± 0.1018 mg/g) and seed extract (14.22 ± 0.09 mg/g). Thirty-six distinct oligosaccharides were discovered between the four samples with three to nine ds.p. and eleven distinct monosaccharide subunits. Overlap existed between the samples’ oligosaccharides with six of the same hexose and hexose-pentose oligosaccharides present in all. Each sample, however, had a distinct oligosaccharide profile such as with eight oligosaccharides unique to the seed extract This study involved multiple reactions and reactants, such as (2S,3R,4S,5S,6R)-2-(3-Hydroxy-5-((E)-4-hydroxystyryl)phenoxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (cas: 27208-80-6Reference of 27208-80-6).
(2S,3R,4S,5S,6R)-2-(3-Hydroxy-5-((E)-4-hydroxystyryl)phenoxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (cas: 27208-80-6) belongs to alcohols. Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes, are valuable intermediates in the synthesis of other compounds, and are among the most abundantly produced organic chemicals in industry. Alcohols may be oxidized to give ketones, aldehydes, and carboxylic acids. These functional groups are useful for further reactions. Oxidation of organic compounds generally increases the number of bonds from carbon to oxygen (or another electronegative element, such as a halogen), and it may decrease the number of bonds to hydrogen.Reference of 27208-80-6
