| heal.abstract | A simple procedure is described for I he simultaneous extraction and HPLC determination of phenols and tocopherols in virgin olive oil. The extraction was carried out using methanol and an isopropanol- methanol mixture. Separation was achieved on a reversed phase C-18 column with acetic acid/water-methanol-acetonitrile-isopropanol mixture under gradient elution. Detection was accomplished with UV detection at lambda==280 nm. Using this method, simple and complex phenols as well as alpha -tocopherol can be determined in one run. Phenolic compounds were totally extracted whereas an average recovery of 80% was achieved for alpha -tocopherol. Validation of method is reported for olive oil samples with varying concentrations of alpha -tocopherol and phenolic compounds. (C) 2001 Elsevier Science Ltd. All rights reserved. | en |
