Abstract: Pitangueira (Eugenia uniflora) is a fruit tree found in the Cerrado, Caatinga, and Atlantic Forest Brazilian biomes. Due to its intense and characteristic aroma and flavor, its fruits (Brazilian cherry) can be consumed raw and as an ingredient in jellies, giving it better use and a more excellent shelf life. The objective of this work was to evaluate the chemical profile of chemical compounds in the pulp, peel, seed, and jelly prepared with the pulp and peel of Brazilian cherry. The characterization of the chemical profile was performed by a fast and simple method: paper spray ionization method coupled with mass spectrometry in positive and negative ionization modes. Forty-six compounds were tentatively identified in the negative mode and 15 in the positive mode, belonging to the classes of phenolic acids, organic acids, fatty acids, hydroxycinnamic acids, sugars, betalains, carotenoids, flavonoids, and tannins. Characterizing these native Brazilian fruits and their products may increase interest in their use, highlighting the potential of Brazilian cherry as a source of nutrients and bioactive compounds. Therefore, developing technological processes for better use and conservation of fruits and, at the same time, identifying the phytochemical compounds present in the product is a way of valuing and preserving our Brazilian biodiversity.
