SUMMARY:

The specie Pouteria macrophylla, popularly known as cutite, has medicinal use for several pathologies, however, few researches present its biological activity, being only reported the antioxidant activity of this fruit from the Amazon. The importance of foods of plant origin has been increasingly evidenced and, among their properties, the antioxidant activity of constituents chemicals in these foods has played an important role. The main purpose of this study is to evaluate the proximate composition, antioxidant capacity and phytochemical potential of the extract of fruits and leaves of Pouteria macrophylla. For this, the collection of botanical material for the preparation of leaf and fruit extracts was carried out at the Tapajos Unit of the Federal University of West do Para, Santarem Campus. The phytochemical characterization of extracts from the fruits and leaves of Pouteria macrophylla was carried out through the quantification of phenolic compounds, flavonoids and tannins. The pulp of P. macrophylla (Lam.) was used to determine the values of moisture, ash, protein, total carbohydrates, total lipids, dietary fiber, carotenoids, total sugars and reducing sugars through of the proximate analysis, and for the investigation of secondary metabolites flavonoids, triterpenoids and tannins, saponins and quinones and anthraquinones, the leaf extract was used. The results showed that P. macrophylla (Lam.) presented 10% of dietary fiber. After analyzing the cutite pulp, a percentage value of 7.5% of ash and 63% of moisture was observed, much higher than the found by other authors. It was demonstrated that the pulp of P. macrophylla (Lam.) does not present an expressive amount of protein, being a food with low protein content. It can be suggested that this fruit has a high antioxidant action, as it presented a high amount of carotenoids in its composition, when compared to other studies carried out. The results after analysis of the extract from the leaf, were positive for flavonoids, triterpenoids and tannins, whereas saponins, quinones and anthraquinones were not detected in the analysis of the P. macrophylla leaf extract. It was found that the leaf and pulp extracts have bioactive compounds, in addition to the presence of secondary metabolites, the results of the DPPH and FRAP antioxidant analyzes showed that the samples have a capacity antioxidant, which characterizes it as a great source of bioactive compounds that can be used in the pharmaceutical industry and in food diets.
