Origanum majorana L. est connu sous le nom de marjolaine, c'est une plante médicinale très riche en huiles essentielles et en polyphénols. Répandue largement dans les pays européens et du Nord d'Afrique. Cette espèce est utilisée en médecine traditionnelle en raison de ses nombreuses caractéristiques thérapeutiques. L'objectif de ce travail est l'étude phytochimique, l'évaluation de l'activité antioxydante et antibactérienne de l'extrait d'une plante médicinale algérienne Origanum majorana L. récolté de la région d'OUED SOUF. Les extraits aqueux et méthanolique ont été obtenus par macération en utilisant l'eau distillée et le méthanol comme solvant et les huiles essentielles par hydrodistillation des feuilles d'Origanum majorana L. On a obtenu le rendement 24% pour l'extrait méthanolique, 20 % pour extrait aqueux et 0.51% pour les huiles essentielles. Le dosage des polyphénols totaux dans les différents extraits est déterminé par la méthode de réactif de Folin-Ciocalteu (FCR). Les teneurs en polyphénols pour l'extrait aqueux et méthanoïque sont respectivement 123,5 7,75 et 134,4 8,43mgEAG/g EXT.
