Origanum majorana L. é conhecida como manjerona, uma planta medicinal muito rica em óleos essenciais e polifenóis. É amplamente difundida nos países europeus e do norte de África. Esta espécie é utilizada na medicina tradicional devido às suas numerosas características terapêuticas. O objetivo deste trabalho é o estudo fitoquímico e a avaliação da atividade antioxidante e antibacteriana do extrato de uma planta medicinal argelina, Origanum majorana L., colhida na região de OUED SOUF. Os extratos aquosos e metanólicos foram obtidos por maceração utilizando água destilada e metanol como solvente e os óleos essenciais por hidrodestilação das folhas de Origanum majorana L. Obteve-se um rendimento de 24% para o extrato metanólico, 20% para o extrato aquoso e 0,51% para os óleos essenciais. A dosagem dos polifenóis totais nos diferentes extratos é determinada pelo método do reagente de Folin-Ciocalteu (FCR). Os teores de polifenóis para o extrato aquoso e metanólico são, respetivamente, 123,5 7,75 e 134,4 8,43 mgEAG/g EXT.
