Abstract: 

The genus Phoenix is one of the most widely cultivated groups of palms around the world. The aim of this study was to determine the antioxidant activity and total phenolic compounds of 14 different varieties of date palm (phoenix dactylifera L., Arecaceae) seed extracts.
Date seeds dried, powdered and extracted by 5 solvents including: Water, Methanol, Methanol 50%, DMSO and Water/Methanol/Acetone/Formic acid (20: 40: 40: 0.1). Anti oxidant activity and total phenolic contents of these extracts were determined by using FRAP value and Folin-Ciocalteu reagent. DMSO extract of Zahedi variety had the highest antioxidant activity (37.42 mmol/100 g dry plant) and total phenolic content (3541 mg /100 g dry plant) among these 14 varieties and 5 solvents. There was a significant correlation between total phenol and antioxidant activity (R2= 0.791, p<0.001) of Zahedi DMSO extract, which can indicates that polyphenols are the main antioxidants. Iranian date palm seed possess relatively high antioxidant activity due to contribution of phenolic compounds. The present study showed that Iranian date seeds are strong radical scavengers and can be considered as a good source of natural antioxidants for medicinal and commercial uses.
