Abstract The objective of the present study was to assess the phenolic compounds and antioxidant capacity of faveleira seed and press cake extracts. Phenolic profiles were assessed by Ultra-High Performance Liquid Chromatography (UHPLC). Furthermore, the Total Phenolic Content (TPC) and DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging were evaluated. The faveleira seed and press cake extracts are sources of natural phenolic compounds in human diet and have potent antioxidant activity. Gallic acid was the predominant phenolic compound in seed and press cake extracts. The study showed that faveleira seed and press cake extracts can be considered functional foods as well as a potential interest to the food industry.
