dc.description.abstractMediterranean countries contribute highly on world peach production and tonnes of waste leaves are released due to pruning. The aim of this study was to investigate the utilization possibilities of the leaves by supercritical fluid extraction. A statistical design was used to evaluate the effect of temperature (40-80 degrees C), pressure (150-300 bar) and concentration of ethanol as co-solvent (6-20%) at a flow rate of 15 g/min and for a duration of 60 min. The most effective variables were found as pressure and co-solvent ratio (p < 0.005). Optimum extraction conditions were elicited as 60 degrees C, 150 bar and 6% co-solvent yielding a total phenol content of 79.92 mg GAE/g extract, EC50 value of 232.20 mu g/ml and a radical scavenging activity of 53.25% which was higher than the value obtained by conventional solvent extraction method (32.23%). Consequently, Prunus persica L. leaves were found as a potential phenolic source for industrial applications. (C) 2014 Elsevier B.V. All rights reserved.en_US
