Extração de sementes de Eugenia involucrata DC com diferentes métodos e solventes

Abstract: O objetivo do trabalho foi avaliar a atividade antioxidante, o teor de compostos fenólicos e flavonoides e a atividade antibacteriana de diferentes extratos de semente de Eugenia involucrata obtidos por extrações sucessivas em Soxhlet e por maceração, utilizando os solventes hexano e álcool etílico. A atividade antioxidante foi fundamentada na medida da absorção do radical 2,2-difenil-1-picril hidrazil (DPPH•) em 515 nm. O teor de compostos fenólicos totais foi avaliado pelo método de Folin Ciocalteu e, os fla… Show more

“…As reported in literature, the contents of flavan-3-ols, organic acids, and phenolic acids in the whole fruit are influenced by their high content in the seed. The seed has generally presented higher TPC value than the pulp plus peel portion of the fruit, as reported by Girardelo et al , 23 Infante et al 9 (22.75 mg GAE per g), and Puton et al 128 (2.28–41.18 mg GAE per g). Gallic acid is an important constituent of cereja-do-Rio-Grande seed phenolic profile, with values varying from 0.005 to 0.074 mg g −1 , depending on the extraction method.…”

“…29,150 Furthermore, the leaves extract has also presented inhibitory potential against several Gram negative bacteria ( Salmonella enterica , Escherichia coli , Klebsiella pneumoniae , Proteus mirabilis , Pseudomonas aeruginosa ), 29 and Candida krusei in the form of an emulsion. 154 According to Puton et al 128 and Albuquerque et al , 25 the seed, residue, and peel extracts are also capable of inhibiting Gram positive ( Bacillus cereus , Listeria monocytogenes , and Staphylococcus aureus ) and negative bacteria ( Escherichia coli , Pseudomonas aeruginosa , Salmonella enterica , and Yersinia enterocolitica ). Furthermore, cereja-do-Rio-Grande seed, residue, and peel extracts could inhibit the growth of Aspergillus brasiliensis and Aspergillus fumigatus at low concentrations.…”
