EFFECT OF OAT GERMINATION ON THE CONTENT OF AVENANTHRAMIDES

Popis výsledku v původním jazyce

Avenanthramides (AVNs) are a group of phenolic compounds found exclusively in oats, and inprocessed oat products. AVNs are found to provide many health benefits in mammals (includinghumans), such as anti-oxidation, anti-inflammation, anti-atherosclerosis, anti-diabetic, antihypertensive,and anti-cancer properties1. The chemical profile and the levels of AVNs in oat varietiesafter germination have been examinated. In the present study, 12 distinct oat varieties weregerminated for 0-192 h and a total of 28 AVNs and 3 AVN-hexosides were determined in thesesamples. Among them, three novel AVNs were synthesized (AVN 1a, AVN 2a, and AVN 2ad),characterized using NMR techniques (1D- and 2D-NMR), and assessed in real samples for the first time.The most abundant AVNs in the samples were AVN 2c, AVN 2p, AVN 2f, and their long-chainedanalogues AVN 2 cd, AVN 2pd, AVN 2fd, together representing 75-85 % of the total AVNs content. Thehighest total AVN level was observed on average after 48-72 h of germination time and it reached avalue 1-1.2 mg/g. Out of 12 investigated oat varieties, CDC Boyer, Diadem, and Rozmar have provedto be the most suitable genotypes for germination
