摘要

This study evaluated the nutritional and chemical profiles and the biological potential of Amazonian berries, including one fruit studied comprehensively for the first time. Oenocarpus bacaba (OB) and Oenocarpus minor (OM) showed considerable levels of proteins, lipids, insoluble fibers, and potassium. The phenolic profile mainly consisted of catechin and apigenin in both, with total phenolic content ranging from 1317.78 to 1387.22 mg GAE/100 g and anthocyanins between 1.04 and 5.59 mg C3G/100 g, in OB and OM, respectively. Antioxidant assays indicated high FRAP, followed by ORAC, mainly for OB. In antiproliferative activity evaluation, OB fluid extract was inactive (GI50 > 150 µg/mL) against a panel of tumor and non-tumor human cell lines. In the scratch assay, OB fluid extract significantly inhibited keratinocyte migration at 100 µg/mL. These findings support the functional food potential of OB and OM, particularly for antioxidant and wound-healing applications.
