    AnnotationThe chemical profile and the levels of AVNs in oat varieties after germination have been examinated. In the present study, 12 distinct oat varieties were germinated for 0–192 h and a total of 28 AVNs and 3 AVN-hexosides were determined in these samples. 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-chained analogues AVN 2 cd, AVN 2pd, AVN 2fd, together representing 75–85 % of the total AVNs content. The highest total AVN level was observed on average after 48–72 h of germination time and it reached a value 1–1.2 mg/g. Out of 12 investigated oat varieties, CDC Boyer, Diadem, and Rozmar have proved to be the most suitable genotypes for germination.
