Abstract

Ara & ccedil;a & uacute;na ( Psidium myrtoides) is a native fruit from the Brazilian Atlantic Forest. It was studied for the proximate composition of its flour and sequential extraction using supercritical fluid extraction (SFE) in the first stage with CO2 and pressurized liquid extraction (PLE) with ethanol and water in the second and third stages, respectively, at 50 degrees C and 60 degrees C. The proximate analysis revealed essential information about the flour regarding the content of protein, carbohydrates, lipid, ash and moisture. The sequential extraction at 60 degrees C resulted in high yields (42.22 %). The first stage using SFE captured the volatile fraction, notably 1,4-diethylbenzene, which corresponds to 53.70 % of the total volatile compounds identified in the ara & ccedil;a & uacute;na. Comparing the second and third stages, the third stage with water at 50 degrees C produced the highest levels of phenolic compounds (33.06+2.26 mg GAE/g extract), total monomeric anthocyanins (3.91+2.10 mg C3G/g extract), antioxidant activity by ORAC (415.13+13.66 mu mol TE/g extract) and FRAP (747.16+18.49 mu mol TE/g extract), and cyanidin-3-glucoside the predominant compound (4.83 % w/w).
