8,5′-Diferulic acid is a non cyclic type of diferulic acid. It is the predominant diferulic acid in sugar beet pulp.[2] It is also found in barley,[3] in maize bran[4] and rye.[5] 8,5′-Diferulic acid has also been identified to be covalently linked to carbohydrate moieties of the arabinogalactan-protein fraction of gum arabic.[6]
