8,5'-Diferulic acid is a non cyclic type of diferulic acid. It is the predominant diferulic acid in sugar beet pulp.^[1] It is also found in barley,^[2] in maize bran^[3] and rye.^[4] 8-5'-Diferulic acid has also been identified to be covalently linked to carbohydrate moieties of the arabinogalactan-protein fraction of gum arabic.^[5]
