Abstract
Some phenolic compounds, (+) catechin, (-) epicatechin, chlorogenic acid, phloretin glucoside (phloridzin) and phloretin xyloglucoside, in several juice samples were separated and identified by reversed phase high performance liquid chromatography/ diode array detection (RP-HPLC/DAD). Dihydrochalcones were identified as 'markers' in apple samples, their content was calculated and a 'threshold concentration' for detectable addition was evaluated. The direct injection method gives excellent recovery, accuracy and precision with a detection limit of 1.6 mg/L. ©1997 Academic Press Limited.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
