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