All extracts were examined by assessing their content in polyphenols and the antioxidant levels were evaluated by two in vitro tests using spectroscopic and the voltametric methods. The quantitative assessment of total phenols and flavonoids by the colorimetric method make it clear that the extracts are very rich of these compounds. The hydro-methanol and methanol extracts gave the highest DPPH and .− 2 O radicals scavenging activities (12.15 μg/ml) and (0.704 mg/ml) respectively.enSalvia Officinalis L, Antioxidant activity, DPPH, Radical superoxide −. 2O , Solvent extraction, Polyphenols, Flavonoids.Article
