The objective of this work is to characterize the phenols and flavonoids compounds of extracts of Pelargonium Graveolens from North-East Morocco (TAZA) in terms of antioxidant activity. The antioxidant activity of 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. The DPPH scavenging activity of extracts increased in the order diethyl ether extract < ethyl acetate extract < ascorbic acid. Based on these results, we suggest that the phenols and flavonoids compounds of Pelargonium Graveolens have significant potential as a natural antioxidant.
