L plant. Which we relied on three extracts, acetone extract, ethanol extract and water ethanol extract. The antioxidant chemical activity of all extracts except acetone showed a small percentage in capturing and inhibiting free radicals of DPPH root, where the ascorbic acid mixture outperformed in the optical absorbance value, which was estimated at 0,529, over all extracts, with a small difference for the ethanol-water extract, where the absorbance reached 0,527 in the test lron FRAP. As for the quantitative estimation of polyphenols, the highest value was 209,71mg/g for ethanolic extract, while for flavonoids, the highest value for acetone extract was with 481,62mg/g at concentration 0,5mg/ml.Arنبات الشريكFagonia Cretica L, antioxidants, extraction, quantification of phenols and flavonoidsMaster
