At samples. The main compounds were classified as hywith decreasing TP values corresponding to increasing protein content material. The highest TP droxybenzoic acids (2), hydroxycinnamic acids (12), flavones (3), lignans (1), hydroxybenvalues in brans were observed in the WB LP, BP fraction. As explained, different trends zaldehyde acids (1) and alkylphenols (three). Therefore, a representative all round phenolic profile, had been observed in relation for the TP and protein content material in grain and bran. This could be due based on chosen ion extraction from the Total Ion Chromatogram, is depicted in Figure to distinctive reasons. The bran is actually a tissue very exposed for the environment, as compared two. to the inner parts with the grain, and it can be there where a higher concentration of a specific type of phenolic compound, mainly connected with fiber, samples by described. Ferulic acid was happen to be HPLC-ESI-QTOF-MS. AbbreTable two. Phenolic compounds identified in WG and WB among the main compounds identified in this study; WB LP is obtained from low-protein viations: WG: wheat grain, WB: wheat bran, FP: absolutely free phenolic fraction, BP: bound phenolic fraction. grains, which correspond to winter varieties. Yu and Beta, [50] reported larger levels in WB WG bound phenolic content in winter wheat varieties, as in comparison to spring varieties.
