A b s t r a c t This study was designed to perform a flavonoid contents and evaluate the antioxidant activity (n analysis of plant extracts was carrie quanti Ciocalteu procedure and aluminium chloride colorimetric method respectively. To evaluate the extract's antioxidant carotene bleaching assay. presence of phenolic acids, flavonoids and isoflavonoids in both extracts. The total phenolic content content (TFC) varied between 53.1 and 48.4 mgQE/g extract for EtOAC and respectively. The using DPPH test and highest antioxidative power (82.42%) using comparing with standards. The HPLC phenolic and f comparing to the phytopharmaceutical importance. Keywords
