燕麦含有一系列对健康有益的酚酸和燕麦胺。用HPLC-DAD分析22种商业燕麦产品（燕麦浓缩物、燕麦麸、燕麦片、燕麦片和燕麦饼），检测出11种结合的和13种游离的 + 共轭酚酸和燕麦胺。燕麦产品(不包括集中)提供在15.79和25.05之间 mg总酚酸(-5.72 4.96 9.9 -19.33 毫克绑定, mg免费 + 共轭)和1.1至2 40毫克的avenanthramides g部分而11 g部分燕麦集中提供总酚酸的16.7 毫克(1.53 15.17 毫克, mg免费 + 共轭)和1.2 avenanthramides毫克。不同产品中各成分的组成和浓度基本相似，主要成分为阿魏酸（58-78.1%）。结果表明，商业燕麦产品对消费者来说是酚酸和燕麦胺的来源。
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.
