abstract={Three varieties of date palm (<i>Phoenix dactylifera</i>) leaves (DPL) namely: Sagaie, Khalas, and Nabtat Alsaif were examined for their antioxidant activities. DPL extracts showed a total phenolic content ranged between 1498.14 ¡À 100.52 - 4374.76 ¡À 657.64 mg gallic acid equivalent (GAE)/100g dry weight (DW) and a total flavonoid ranged between 134.70 ¡À 16.24 - 224.62 ¡À 22.35 mg quercetin (QE)/100g (DW). The IC<SUB>50s</SUB> for scavenging ABTS radical were ranged between 71.87 ¡À 14.37- 217.87 ¡À 27.40¦Ìg Trolox equivalent, whereas that required for scavenging DPPH were ranged between 197.86 ¡À 17.60-693.32 ¡À 25.44 ¦Ìg ascorbic acid equivalent. DPL extracts potentially scavenged hydroxyl and superoxide anion radicals, IC<SUB>50s</SUB> values were ranged between 208.04 ¡À 12.76-719.63 ¡À 24.38 and 825.92 ¡À 19.40 -1193.20 ¡À 28.74¦Ìg GAE respectively. DPL extracts showed a good activity against ferric reducing antioxidant power (FRAP) ranged between 7.69 ¡À 0.47- 22.13 ¡À 1.36 mmol ascorbic acid equivalent/100g. DPL extracts showed a considerable antioxidant activity, therefore, DPL could be effectively used as natural source of antioxidant in food and pharmaceutical industries.},
