Finland is the second largest oat producer in Europe. Despite the existing knowledge of phenolics in oat, there is little information on the phenolic composition of oats from Finland. The aim of the study was to investigate the concentrations of free and bound phenolic acids, as well as avenanthramides in eight Finnish cultivars of husked oat ( Avena sativa L.). Seven phenolic acids and one phenolic aldehyde were identified, including, in decreasing order of abundance: p-coumaric, ferulic, cinnamic, syringic, vanillic, 2,4-dihydroxybenzoic, and o-coumaric acids and syringaldehyde. Phenolic acids were mostly found as bound compounds. Significant varietal differences ( p < 0.05) were observed in the cumulative content of phenolic acids, with the lowest level found in cv. 'Viviana' (1202 ± 52.9 mg kg-1) and the highest in cv. 'Akseli' (1687 ± 80.2 mg kg-1). Avenanthramides (AVNs) 2a, 2p, and 2f were the most abundant. Total AVNs levels ranged from 26.7 ± 1.44 to 185 ± 12.5 mg kg-1 in cv. 'Avetron' and 'Viviana', respectively.

八种来自芬兰的燕麦燕麦（Avena sativa L）品种中的Avenanthramides和游离和结合的酚酸的鉴定和定量。
芬兰是欧洲第二大燕麦生产国。尽管已有燕麦中酚类物质的知识，但有关芬兰燕麦中酚类成分的信息很少。这项研究的目的是调查8个芬兰燕麦（Avena sativa L.）品种中游离和结合的酚酸以及avenanthramides的浓度。鉴定了7种酚酸和1种酚醛，包括含量从高到低的递减顺序：对香豆酸，阿魏酸，肉桂酸，丁香酸，香草酸，2,4-二羟基苯甲酸和邻香豆酸和丁香醛。酚酸大多被发现是结合的化合物。酚酸的累积含量观察到明显的品种差异（p <0.05），而cv中的含量最低。'Viviana'（1202±52.9 mg kg-1）和最高的简历。' Akseli'（1687±80.2 mg kg-1）。Avenanthramides（AVNs）2a，2p和2f含量最高。AVN的总水平范围从26.7±1.44到185±12.5 mg kg-1（cv）。分别是“ Avetron”和“ Viviana”。
