The scope of this work was to determine the possibility of the application of the pulsed\nelectric field (PEF) technique to the production of extracts from Moringa oleifera plant material\n(freeze-dried leaves). Various PEF conditions (pulse durationâ??PD; and pulse intervalâ??PI) were\ntested. A field strength of 7 kV/cm was used. The total phenols in the extracts were evaluated by\nthe Folinâ??Ciocalteu method and the antioxidant activity was evaluated by the radical scavenging\nactivity (DPPHâ?¢), ferric reducing antioxidant power (FRAP) and Rancimat methods. The results\nwere compared with those of the extracts obtained using other extraction techniques, namely\nmicrowave-assisted and ultrasound-assisted extractions, simple boiling water extraction, and plain\nmaceration with water (as the control). The highest extraction of total phenols was achieved by\nthe PEF procedure using 40 min treatment at a PD of 20 msec and a PI of 100...............
