ANÁLISE FITOQUÍMICA E AVALIAÇÃO DA SUSCEPTIBILIDADE ANTIMICROBIANA DE DIFERENTES TIPOS DE EXTRATOS DE Plantago major L. (Plantaginaceae)

Abstract

Plantago major L. is a plant from the European continent, used for medicinal purposes. It presents hematopoietic activity, and has been in the treatment of leukemia, carcinoma and against viruses. Other activities include antiparasitic, diuretic, hepatoprotective and anti-inflammatory. Ttherefore, this study evaluated the phytochemical profile of aqueous, ethanol and hydroalcoholic extracts of Plantago major L. leaves, as well as the antimicrobial action to Gram-positive and Gramnegativestrains. The results of the phytochemical analysis showed the presence of tannins, saponins, alkaloids, flavonoids, terpenes and glycosides. Antimicrobial analysis demonstrated ethanol extracts and hydroalcoholic of Plantago major L. have an antimicrobial action to Staphylococcus aureus, through the actions of bioactive metabolites with antimicrobialactivity, such as tannins and flavonoids, which would become the Plantago major L. possible candidate for a new herbal medicine.  Plantago major L. is a plant from the European continent, used for medicinal purposes.
