Antioxidants Activity of Date Seed Extraction of Some Date Varieties

The study included preparing aqueous , alcoholic, and oil extractions of date seed power of (Phoenix dactylifera)Al Hillawi, Al Khadhrawi and Al ZAHDY date varieties estimating its total contents of phenol and flavonoids, and then it is studied its antioxidants activity, reduction strength and ability to bon Ferrous ion. The results showed that total contents of phenolic compounds are ranged from 56.16 to 67.32 mg/ml for the ethanol extraction, 56.6 to 65.6 to 65.32 mg/ml for methanolic extract and 27.88 to 40.06 mg/ml for aqueous extraction. While the total contents of flavonoids of aqueous extract is ranged from 22.12. to 33.32 mg/ml, 40.21 to 52.16 mg/ml in the ethanolic extract and from 35.11 to 46.16 mg/ml in the methanol extraction. Indeed,aqueous and alcoholic extract of (Phoenix dactylifera) Al Hillawi, AlKhadrawai and Al Zahdy give Antioxidation activity are ranged from 37.50% to 88.70%, reduction strength is ranged from 0.895 to 2.63 and the value of Ferrous ion bon is ranged from 41.92% to 60.93%.
