P.  aComprehensive identification and quantification of unexploited phenolic compounds from red and yellow araçá (Psidium cattleianum Sabine) by LC-DAD-ESI-MS/MS.h[electronic resource]  c2020  a9 p.  aAvailable online 7 January 2020.  aLC-DAD-ESI-MS/MS was used to comprehensively characterise the non-extractable phenolic compounds (NEPC) in red and yellow araçá genotypes. Results showed a total of 45 and 43 phenolic compounds in the NEPC fraction and, similarly, 51 and 50 compounds in extractable phenolic compounds (EPC) fraction from red and yellow araçá, respectively. Gallic acid and ellagic acid were the unique compounds found in both fractions. The NEPC fraction represented about 35% (m/m) of the total phenolic content and was characterised by an abundance of phenolic acids, while the EPC fraction was rich in flavanols. Although NEPC represented one-third of the total phenolic compounds found in araçá, its antioxidant capacity (against peroxyl radical) was 50% higher than the EPC fraction. The results of this work show that the NEPC fraction of araçá has great diversity and a relatively high concentration of low-molecular-weight phenolic compounds with high antioxidant capacity.  aAraçá1 aTISCHER, B.1 aVIZZOTTO, M.1 aRODRIGUES, E.1 aMANFROI, V.  tFood Research Internationalgv. 131, May 2020.
