Various ferulic acid (FA) dimers occurring in plant cell walls, such as 8-5-, 8-O-4-, 5-5-, and 8-8-coupled dimers, are effective antioxidants and potential antimicrobials. It is necessary to access these diferulates as reference compounds to validate those isolated from plants. 3,6-bis(4-hydroxy-3-methoxyphenyl)-tetrahydrofuro-[3,4-c]furan-1,4-dione, a 8-8-coupled FA dilactone generated from ferulic acid via radical coupling, has been used to synthesize 8-8-coupled FA dimers although few reports investigated the distribution of products and mechanisms involved in the transformation of FA dilactone. In this work, the FA dilactone, obtained from FA by a peroxidase-catalyzed radical coupling, was reacted under various base/acid conditions. Effects of reaction conditions and workup procedures on the distribution of products were investigated by GC-MS. The isolated products from such treatments of FA dilactone were characterized by NMR. New derivatives of FA dimer including 2-(4-hydroxy-3-methoxybenzylidene)-3-(hydroxyl-(4-hydroxy-3-methoxyphenyl)methyl)succinic acid and 2-(bis(4-hydroxy-3-methoxyphenyl)-methyl)-succinic acid were produced from NaOH treatment. Another novel 8-8-coupled cyclic FA dimer, diethyl 6-hydroxy-1-(4-hydroxy-3-methoxyphenyl)-7-methoxy-1,2-dihydronaphthalene-2,3-dicarboxylate was identified in products from FA dilactone treated by dry HCl in absolute ethanol. Mechanisms involved in such transformations were proposed.

Fractions enriched in the cell walls of wheat and barley scutella were prepared from isolated, ungerminated scutella. The cell-wall fractions were subjected to hot, alkaline extraction under an inert atmosphere. An ether extract was investigated for phenolic compounds by thin-layer chromatography using three solvent systems and by ultraviolet spectroscopy. The major autofluorescent component of the scutella of both wheat and barley is ferulic acid. There is apparently no p-coumaric acid.

Removal of ferulic acid from barley aleurone cell walls is closely correlated with wall hydrolysis. The ferulic acid content of isolated aleurone layers (Hordeum vulgare L. cv. Himalaya) falls progressively during incubation with gibberellic acid (GA3), to about one-third of the original content, by 72 h. At the same time an equivalent amount accumulates in the incubation medium, not as the free acid but still esterified to other components. The data show that there is no modification of the feruloyl group, or hydrolysis of the ester linkage prior to removal from the tissue, and therefore the GA3-induced aleurone peroxidases and esterases are not directly involved.
