Brazilian berry waste as a source of bioactive compounds: grumixama (Eugenia brasiliensisLam.) as a case study

Abstract

Grumixama, Eugenia brasiliensis Lam., is a Brazilian berry little explored commercially and scientifically. However, local small producers market this fruit in the form of frozen pulp, which generates bioresidues, composed...

Recovery of anthocyanins from Eugenia spp. fruit peels: a comparison between heat- and ultrasound-assisted extraction

“…20 The detected anthocyanins were identied by comparing their retention times and UV-Vis and mass spectra with data from the literature. 21,22 This way, four anthocyanins were found in E. brasiliensis fruit peel extract, namely delphinidin-3-O-glucoside, cyanidin-3-O-galactoside, cyanidin-3-O-glucoside, and cyanidin-3-O-arabinoside, while E. involucrata fruit peel extract contained the same anthocyanins plus delphinidin-3-O-glucoside, thus totalizing ve compounds. These anthocyanins were quantied (as mg per g extract, E) using a seven-level calibration curve constructed with a commercial standard of cyanidin-3-O-glucoside (y = 129 688x − 42 802; r 2 = 0.9969); limits of detection and quantication of 0.59 mg mL −1 and 1.81 mg mL −1 , respectively.…”
