Oats contain a range of phenolic acids and avenanthramides which may have health benefits. Analysis of 22 commercial oat products (oat bran concentrate, oat bran, flaked oats, rolled oats and oatcakes) using HPLC-DAD detected eleven bound and thirteen free + conjugated phenolic acids and avenanthramides. The oat products (excluding concentrate) provided between 15.79 and 25.05 mg total phenolic acids (9.9–19.33 mg bound, 4.96–5.72 mg free + conjugated) and between 1.1 and 2 mg of avenanthramides in a 40 g portion while an 11 g portion of oat concentrate provided 16.7 mg of total phenolic acids (15.17 mg bound, 1.53 mg free + conjugated) and 1.2 mg of avenanthramides. The compositions and concentrations of the components in the different products were broadly similar, with the major component being ferulic acid (58–78.1%). The results show that commercial oat products are a source of phenolic acids and avenanthramides for consumers.

Highlights • Commercial oat products contained ten phenolic acids and three avenanthramides. • Commercial oats provide 15.79–25.05 mg total phenolic acids in a 40 g serving of oats. • The concentrations and compositions in the products were broadly similar. • Major component was ferulic acid (58–78.1%) in all products. • Oatbran concentrate has the highest levels of phenolic acids and avenanthramides., Oats contain a range of phenolic acids and avenanthramides which may have health benefits. Analysis of 22 commercial oat products (oat bran concentrate, oat bran, flaked oats, rolled oats and oatcakes) using HPLC-DAD detected eleven bound and thirteen free + conjugated phenolic acids and avenanthramides. The oat products (excluding concentrate) provided between 15.79 and 25.05 mg total phenolic acids (9.9–19.33 mg bound, 4.96–5.72 mg free + conjugated) and between 1.1 and 2 mg of avenanthramides in a 40 g portion while an 11 g portion of oat concentrate provided 16.7 mg of total phenolic acids (15.17 mg bound, 1.53 mg free + conjugated) and 1.2 mg of avenanthramides. The compositions and concentrations of the components in the different products were broadly similar, with the major component being ferulic acid (58–78.1%).

Polyphenols are found ubiquitously in plants, and epidemiological studies suggest an association between their regular consumption and a reduced risk of a number of chronic diseases; such as cardiovascular disease, specific forms of cancer, and neurodegenerative disease. The mechanisms by which polyphenols express these beneficial properties appear to involve their interaction with cellular signaling pathways and related machinery that mediate cell function under both normal and pathological conditions. Thus, their effectiveness and mechanisms of action in vivo will be dependent on the extent of their biotransformation. Native polyphenols in the diet are subjected to extensive metabolism following oral ingestion, in the upper gastrointestinal tract and in the colon, and after reaching the circulation, further intracellular metabolism in target tissues may occur. Additionally, the blood-brain barrier’s crossing ability will influence their effect in the brain. This chapter will give an overview of how the polyphenols’ bioavailability is influenced by gastrointestinal modifications, blood-brain barrier transport, intracellular metabolism, and the impact on their mechanisms of action.
