Abstract
Algerian Salvia Officinalis L aerial parts were extracted with pure solvents in increasing
polarity (hexane, acetone, methanol and 80% aqueous methanol. 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.
