Antioxidant activity of phenols and flavonoids contents of aqueous extract of Salvia Officinalis origin in the North-East Morocco

Oxidative stress is responsible for several diseases. This phenomen has moved researchers into action in looking for new remedies «antioxidants». The aim of this work was to characterize the phenols and flavonoids compounds of extracts of Salvia Officinalis from North-East Morocco (TAZA) in terms of antioxidant activity. The antioxidant activityof this aromatic plant was determined according to the DPPH radical scavenging assay to suggest it as a new potential source of natural antioxidants. The quantification of phenolics and flavonoids compounds of solvent extracts (diethyl ether and ethyl acetate) were determined spectrometrically. Furthermore, The DPPH scavenging activity of extracts increased in the order diethyl ether extract < ethyl acetate extract < ascorbic acid. Finally, we suggest that the phenols and flavonoids compounds of Salvia Officinalis has significant potential as a natural antioxidant.
