Characterization and antioxidant activity of avenanthramides from selected oat lines developed by mutagenesis technique
From a mutagenized oat population, produced by ethyl methanesulfonate mutagenesis, hulled grains from 17 lines with elevated avenanthramide (AVN) content were selected and their AVN structures, concentrations and antioxidant potentials were determined by HPLC-MS2 and HPLC equipped with an on-line ABTS+ antioxidant detection system. The data obtained showed qualitative and quantitative differences
