    Oximes of isoxanthohumol (IXN), naringenin (N) and flavanone (FL) were synthesized with yields of 88-95% and their antioxidant activity was evaluated using the 1,1-diphenyl-2-picrylhydrazyl radical (DPPH) method. Although naringenin oxime (NOX) and flavanone oxime (FLOX) did not have any significant antioxidant effect (EC50=2.21 mM and 78.7 mM, respectively), isoxanthohumol oxime (IXNOX) showed a strong antioxidant activity (EC50=0.0411 mM), comparable to the activity of ascorbic acid (EC50=0.0181 mM). The structure of new compound IXNOX was established using (1)H NMR, (13)C NMR, IR and UV-VIS spectroscopy, by comparison to IXN, NOX and FLOX.
