Abstract

This study aims to determine the factors affecting the process of extraction of phenolic compounds from olive leaves. Two methods of extraction were used in this work and different tests were implemented with the aim of optimizing the recovery of phenolic compounds from olive leaves. The factors considered were the extraction time, temperature, solvent-solid ratio and the ethanol concentration. Obtained results show that the recommended optimal conditions for the extraction of the total phenolic compounds from olive leaves were found at 40°C with a solvent/solid ratio of 30:1 and ethanol concentration of 80% (v/v) when the dried olive leaves are stored at -21°C at the beginning of the experiments.
