Abstract

Brazil has a rich and diverse flora which we can obtain the active ingredients that can be used in food, cosmetics or new drugs. Increasingly growing concern of people with improved quality of life and well-being, which gives incentives as well, needs to develop new products, such as cosmetics. This study aimed to determine the total phenolic content, the ability to scavenge free radicals and antimicrobial activity of leaf extracts of Eugenia uniflora L. and the Bromelia balansae Mez and for their application in the formulation of cosmetics. The Pitanga or Eugenia uniflora L. showed a great quantity of phenols, which improves the preservation of cosmetics, assisting in prevention of premature aging, moreover, this species showed better results as the ability to scavenge free radicals at high concentrations and, for inhibition of microbial activity it had good development as the strains of Escherichia coli and Staphylococcus aureus, while the Gravatá or Bromelia balansae Mez only inhibited the growth of Escherichia coli. Perceiving, then, that the extract from the leaves of Pitanga may be incorporated in the formulation of creams to prevent skin blemishes and wrinkles attenuation.
