Abstract

Uvaia ( Eugenia pyriformis Cambess) is a Brazilian native fruit with a high concentration of phenolic compounds. In this study, we optimized the extraction of flavonoids and other phenolic compounds from uvaia pulp (UP) and seed (US) by Pressurized Liquid Extraction (PLE) using an ethanolic solution as solvent. Both temperature and ethanol concentration enhanced the extraction of the phenolics from UP and US. The increase in ethanol concentration decreased the yield of flavonoid extraction from UP. In the case of the US, higher temperatures and lower ethanol percentage improved the yield of flavonoid extraction. All extracts showed high antioxidant activity under optimized conditions, especially the US extracts (507.40 mu M Trolox.g-1 of dry US). The present findings highlight the effectiveness of PLE in obtaining antioxidant extracts from UP and US, and also contribute to the valorization of uvaia fruit and its residues. (AU)
