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 with 5 solvents [water, methanol, methanol )50percent(, DMSO, and water: methanol: acetone: formic acid )20:40:40:0.1([. Ferric reducing antioxidant power assay and Folin-Ciocalteu reagent was used for determination of the antioxidant effect and phenolic content of date seeds. DMSO extract of theع Zahedi عvariety had the highest antioxidant effect )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 the total phenolic content and antioxidant activity )R2 = 0.791, P < 0.001( of theع Zahedi عvariety DMSO extract, which can indicates that polyphenols are the main antioxidants. Iranian date palm seed has a relatively high antioxidant activity due to contribution of phenolic compounds. The present study showed that the Iranian date seeds are strong radical scavengers and can be considered as a good source of natural antioxidants for medicinal and commercial uses.
