ABSTRACT

Introduction: the yellow mammee (Mammea americana L.) is widely used to cure different diseases caused by parasites and insects.
Objective: to perform a phytochemical screening and to determine antibacterial activity of dry extracts of 20 % tincture from the leaves and the bark of this plant.
Methods: the leaves and stem bark of the plant were harvested, washed, disinfected, dried and crushed. Then it proceeded to the preparation of 20 % tinctures through drug maceration. The dried extracts of the studied parts were obtained from the 20 % tinctures and used to evaluate the phytochemical screening tests and the antibacterial activity.
Results: the existence of a high diversity of secondary metabolites, predominantly alkaloids, coumarins, phenols and / or tannins, quinones, and flavonoids were confirmed. The dried extracts showed antibacterial activity in vitro against Staphylococcus aureus (ATCC 29737).
Conclusions: flavonoids, alkaloids, tannins and coumarins, which are of biological and pharmacological interest for their potential therapeutic applications, were significantly present in these extracts.
