\nPDF<\/strong><\/a><\/td>\n		Three common wheat cultivars (Triticum aestivum<\/em> L.) were grown under the reduced and optimal nitrogen (N) levels during 2018\/2019 vegetation season. In this study, phenolic compounds were analysed as soluble-free and insoluble-bound fractions, because the majority of them are found in cereals in these forms. Total phenolic content in both extracts (TPC) was determined using the Folin-Ciocalteu reagent, while the antioxidant activity (AOA) of phenolics was evaluated using the 2,2\u2013diphenyl\u20131\u2013picrylhydrazyl radical scavenging test. The composition and content of phenolic acids (PAs) was analysed by HPLC. On average, TPC and AOA values were several times higher in the insoluble\u2013bound extract compared to the soluble\u2013free one (163.2 mg GAE\/100 g DM vs<\/em>. 60.7 mg GAE\/100 g DM, and 48.5% vs<\/em>. 17.6%, respectively). Soluble\u2013free PAs ranged from 4.0 mg\/100 g DM (p\u2013coumaric acid) to 4.6 mg\/100 g DM (p\u2013hydroxybenzoic acid), while insoluble\u2013bound PAs content was much higher, ranging from 2.2 mg\/100 g DM (caffeic acid) to 56.5 mg\/100 g DM (ferulic acid). For phenolic extracts, TPC, AOA and almost all PAs content was higher under the reduced nitrogen levels. In general, insoluble\u2013bound PAs were more susceptible to higher nitrogen supply than soluble-free ones. Although cultivars showed a similar response to increased nitrogen rate, considerable variability in their phenolic properties was observed.<\/td>\n<\/tr>\n
