Abstract

Brazilian native fruits (BNF) remain unexplored and underutilized resources with a high potential to improve human health and wellness. In our study, five new BNF (Eugenia stipitata, Sageretia elegans, Byrsonima arthropoda, Spondias mombin and Rubus rosaefolius) were evaluated for their phenolic composition by LC-ESI-QTOF-MS; and for their ROS and RNS scavenging effects (ROO center dot, O-2(center dot-), NO center dot, HOCl); in vivo anti-inflammatory activity (neutrophil migration); and in vivo acute toxicity in Galleria mellonella. Eighty-six phenolic compounds were identified, including hydroxybenzoic acids, hydroxycinnamic acids, flavonoids, anthocyanins and ellagitannins, several of which had never been reported in BNF. The BNF exhibited high antioxidant effects against biologically relevant radicals, and treated animals showed decreased neutrophil influx and NF-kB activation. Thus, these BNF are good sources of antioxidant and anti-inflammatory molecules that can be beneficial for human health as functional foods. Based on their bioactivity, they can be considered as new Brazilian superfruits. (AU)
