Resumo

In this study, Eugenia calycina and Eugenia stigmatosa, native Brazilian berries, were explored regarding their proximal composition, bioactive compounds, and antioxidant activities. The edible parts of both fruits presented a low content of lipids, proteins, and carbohydrates, resulting in a low caloric value (<70 kcal/100 g fw). E. stigmatosa fruit showed a high total fiber content (3.26 g/100 g fw), qualifying it as a source of dietary fiber. The sugar profile was mainly monosaccharides (glucose, fructose, and rhamnose). Significant contents of total phenolics and flavonoids, monomeric anthocyanins and, condensed tannins, were observed in both fruits. E. calycina contains a high level of anthocyanins, primarily cyanidin-3-glucoside (242.97 <mu>g/g). Other phenolic compounds were also found, the main ones being rutin and ellagic acid. In contrast, E. stigmatosa is mainly composed of rutin and gallic acid. Furthermore, these fruits showed expressive antioxidant activity, evidenced by ORAC, FRAP, and ABTS. These Eugenia fruits are promising sources of bioactive compounds and have a low caloric and high dietary fiber content, making them interesting options for inclusion in a balanced diet, contributing to the promotion of health and the valorization and conservation of Brazilian biodiversity.
