Abstract

Berries of Colombian Euterpe oleracea Mart. were analyzed for total phenolic content (TPC), anthocyanin (ACN) content, and antioxidant activity. Additionally, reversed-phase ultra-high performance liquid chromatography with photodiode array detection (RP-UHPLC-PDA) and heated electrospray ionization (HESI) multistage mass spectrometry (MSⁿ) were used to determine the composition of phenolic compounds. Anthocyanin content was 0.57 ± 0.39 mg cyanidin-3-glucoside/g fresh weight (FW) and TPC was 6.07 ± 2.17 mg gallic acid equivalent (GAE)/g FW. The ABTS radical scavenging activity was 3.1 ± 1.3 μmol Trolox equivalents (TE)/100 g FW, whereas the DPPH value was 2693.1 ± 332.8 μmol TE/100 g FW. Overall, results show that Colombian açai has a more diverse polyphenolic profile and higher antioxidant activity than Brazilian açai. This information could be useful in authentification procedures to differentiate Brazilian açai from Colombian açai when used as an alternative for the supply of this fruit during the time of shortage in Brazil.
