Abstract
The aim of the present study is to investigate the effects of solvent type (ethanol, methanol, acetone and water), acetone concentration (20–100%, v/v), solvent acidity (0–2 N), time (30–450 min) and temperature (25–70 °C) on the extraction of total phenolic compounds (TPC), total flavonoid compounds (TFC) and on the antioxidant capacity: 1,1-diphenyl-2-picrylhydrazyl radical-scavenging activity (DPPH-RSA) and ferric reducing power (FRP) of peach fruit (Prunus persica L.) using single factor experiments approach. All the studied extracting conditions showed significant effect (p < 0.05) on TPC, TFC, DPPH-RSA and FRP. On the basis of TPC and antioxidant activity parameters, the best extraction conditions were 60% acetone without acidification for 180 min at 25 °C. Based on these optimized conditions, high content of TPC, DPPH-RSA and FRP of peach extracts were obtained with values of 363 GAE/100 g, 48% percentage of inhibition and 317 AAE/100 g, respectively. Good, positive or negative, Pearson correlation coefficients were found between TPC, TFC DPPH-RSA and FRP of peach extracts, especially under the influence of solvent type, solvent concentration and acidity extraction conditions.
