5-8'-Dehydrodiferulic acid
IUPAC 名称
(2E)-2-{5-[(1Z)-2-carboxyeth-1-en-1-yl]-2-hydroxy-3-methoxyphenyl}-3-(4-hydroxy-3-methoxyphenyl)prop-2-enoic acid
描述
5-8'-dehydrodiferulic acid is a member of the class of compounds known as stilbenes. Stilbenes are organic compounds containing a 1,2-diphenylethylene moiety. Stilbenes (C6-C2-C6 ) are derived from the common phenylpropene (C6-C3) skeleton building block. The introduction of one or more hydroxyl groups to a phenyl ring lead to stilbenoids. 5-8'-dehydrodiferulic acid is practically insoluble (in water) and a moderately acidic compound (based on its pKa). 5-8'-dehydrodiferulic acid can be found in a number of food items such as corn, common wheat, rye, and semolina, which makes 5-8'-dehydrodiferulic acid a potential biomarker for the consumption of these food products. 8,5'-Diferulic acid is a non cyclic type of diferulic acid. It is the predominant diferulic acid in sugar beet pulp. It is also found in barley, in maize bran and rye. 8-5'-Diferulic acid has also been identified to be covalently linked to carbohydrate moieties of the arabinogalactan-protein fraction of gum arabic .
