    For metabolomic analysis of maize plants growing under different nitrogen nutrition sequential extraction of fresh biomass was used and isolated fractions were characterized and evaluated using IR spectra. The IR spectra of individual fractions were evaluated in relation to the nitrogen rates (2 g or 4 g N), to applied fertilizers (ammonium nitrogen or urea ammonium nitrate solution) and sampling period. For butanol fraction, typical bands of flavonoids, polar phospholipids, steryl glycosides, analogues of ecdysteroids were characterized. The IR spectra of BuOH fraction showed changes of relative contents of isolated compounds mainly affected by nitrogen rates. For water fraction bands of organic acids, salts of organic acids, flavonoid glycosides and oligopeptides (phytochelatins and/or glutathione) were the most significant. The results showed an increased induction of oxalic acid in plants after 4 g N application.
