Abstract

Araçá or strawberry guava (Psidium cattleianum Sabine) is an attractive tasty small fruit native to temperate zones of Brazil. In this study, functional chemical constituents and the nutraceutical and therapeutic potential of aqueous and acetone extracts of red and yellow accessions of araçá were characterised. While carotenes, ascorbic acid, and anthocyanins were present as minor constituents, araçá fruit presented high levels of phenolic compounds (up to 768mg 100g−1 fresh fruit pulp, ffp), particularly (−)-epicatechin (up to 2.7mgg−1 ffp), which were in general more efficiently extracted with acetone. Abundance of phenolic compounds was positively correlated with antioxidant activity, antimicrobial and antiproliferative effects.
