Abstract
Some phenolic compounds, (+) catechin, (-) epicatechin, chlorogenic ac id, phloretin glucoside (phloridzin) and phloretin xyloglucoside, in s everal juice samples were separated and identified by reversed phase h igh performance liquid chromatography/diode array detection (RP-HPLC/D AD). Dihydrochalcones were identified as 'markers' in apple samples, t heir content was calculated and a 'threshold concentration' for detect able addition was evaluated. The direct injection method gives excelle nt recovery, accuracy and precision with a detection limit of 1.6 mg/L . (C) 1997 Academic Press Limited.
