Abstract
The purpose of the present investigation was to characterize the pitanga seeds on centesimal composition, and also to evaluate its antioxidant potential and fatty acid profile. For obtaining the extract, the dehydrated
and ground seeds were treated with ethyl alcohol for 30 minutes, at a proportion of 1:3 of seeds:ethyl alcohol, under continuous agitation at room temperature. Afterwards, the mixture was filtered and the supernatant was placed into a rotoevaporator at 40ºC for determining the extract’s dry matter yield, by direct weighing. According to the results, the seeds of cherry showed high amounts of carbohydrates, and offer relevant content and antioxidant activity of phenolic compounds. In the seed oil, cherry high lighted a higher percentage of unsatured fatty acids, oleic being the main component.
