## Abstract The retention of phenolic acid and flavone antioxidants was investigated on three columns with bonded PEG, hydroxy (DIOL) and mixed oxyethylene‐hydroxy (Luna HILIC) stationary phases in buffered aqueous ACN mobile phases. All columns show mixed retention mechanism: reversed phases in hi
