| Summary: | Several investigations are carried out involving antioxidant compounds from natural
sources due to their importance in preventing the onset of oxidative reactions. Brazil has a rich
biodiversity, having species with a high antioxidant potential already scientifically proven, and which has
contributed to popular medicine. The objective of this work is to evaluate the antioxidant activity (AA0%)
of the leaf, bark and mature and green pseudofruit of the Anacardium occidentale species through the
qualitative and quantitative evaluation of the cashew tree by the radical sequestration capacity DPPH •
(2,2-diphenyl- 1-picrylhydrazyl) of purple coloring. In the qualitative and quantitative analysis, the plant
species presented antioxidant activity in all the tested concentrations (100, 200, 300, 400 and 500μg.mL1). The leaf was characterized by 80.43% AAO in the concentration of 500μg.mL -1 as well as its shell at
the same concentration showed an antioxidant activity of 78.31%. The Folin-Ciocalteu method was able
to determine the total phenol content (FT), with a leaf content of 0.0800 mg / g gallic acid, which is
directly linked to antioxidant activity. Thus, it is well known that Anacardium occidentale is a species with
excellent antioxidant activity, which will further contribute to the pharmacological and folk medicine
industries.
