Abstract null null The aim of this work was to evaluate the bioaccessibility, cytotoxicity, antioxidant and antidiabetic potential of peel and seeds of cupuassu (Theobroma grandiflorum). Thus, the extracts of cupuassu were evaluated for inhibition of α-amylase, cytotoxicity, and bioaccessibility after gastrointestinal digestion and probiotic fermentation (Lactobacillus delbrueckii, Lactobacillus jhonsoni, Lactobacillus rhamus and Bifidobacterium longum). Digestion increased concentrations of phe...

Abstract null null This study aims to investigate the fruit residues of cashew apple and soursop regarding their chemical composition (sugars, carotenoids and organic acids by HPLC-DAD/RID), total phenolics, flavonoids, antioxidant capacities (ABTS, DPPH, FRAP and ORAC), inhibition of α-amylase enzyme, cytotoxicity by cell viability of fibroblast cells lines (L929). The aqueous and ethanolic extracts were submitted to simulated in vitro gastrointestinal digestion and probiotic fermentation (Lact...

Abstract null null The aim of this study was to analyze the aqueous and ethanolic extracts of fruits (pomegranate, jambolan, jackfruit, physalis and bitter melon) residues regarding the assessment of α-amylase inhibition, cytotoxicity and bioaccessibility of phenolic compounds, flavonoids and antioxidants after the in vitro gastrointestinal digestion and fermentation with probiotics and phenolic compounds by UFLC-DAD. The extracts showed a high rate of α-amylase inhibition, presenting a possible...

Abstract null null The aim of this study was to analyze the residue powders of Malpighia emarginata L., Psidium guajava L., Genipa americana L. and Spondias tuberosa L. regarding their total phenolic compounds contents, antioxidant activity (ABTS, DPPH and FRAP), soluble sugars, carotenoids, organic acids by HPLC-DAD/RID and individual phenolic compounds by the UPLC-QDa-MS system. The genipap residue had a high content of soluble sugars (422.72 ± 19.15 mg.g-1 DW), with a higher content of sucros...

Abstract The aim of this study was to analyze eight selected species of leaves, used in the traditional medicine of the Northeast region of Brazil obtained from several fruit trees (grageru, soursop, jambolanum, passion fruit, insulin, nogueira, pedra ume kaa and stevia), regarding their polyphenols contents and antioxidant activity. Condensed and hydrolysable tannins, phenolics and flavonoids contents were determined and the antioxidant activities measured by ABTS, FRAP and ORAC assays. Organic...

Abstract The present study aims to characterize leaf, bark and seed of monguba in terms of their physicochemical and bioactive composition, and to determine total phenolic compounds (TPC) and total flavonoids (TF), well as their antioxidant activities (AA), of three organic solvent extracts with and without enzyme pretreatment by ultrasonic assisted extraction. Physicochemical composition was measured by pH, total titratable acidity, total soluble solids, moisture, ashes, lipids, crude protein, ...

Abstract The aim of this work was to undertake an extensive study on the bioactive compounds and inhibition of the α-amylase of Litopenaeus vannamei and Ucides cordatus residues and report the effect of gastrointestinal digestion on the phenolic content and antioxidant activity of its extracts. The carotenoid astaxanthin was quantified in all the residues, while canthaxanthin was identified only in L. vannamei (0.240 mg/g). Naringenin was the major phenolic compound quantified in L. vannamei (17...

Abstract A bioaccessibility study on polyphenols, flavonoids and antioxidant capacity after the in vitro simulated digestion was evaluated for extract of fruit (caja-umbu, cashew apple, canafistula, cupuassu, soursop, manguba and strawberry) residues. The results show that ORAC assay presented a significant increase (p ≤ 0.05) in bioaccessibility varying from 35.99 ± 0.02% (caja-umbu residue) to 339.83 ± 0.06% (cupuassu residue) after the digestion process. Approximately 15.01 ± 1.54 to 237.77 ±...

Abstract Edible flowers are receiving renewed interest as potential sources of bioactive compounds. The present study aimed to investigate the presence of bioactive compounds and antioxidant activity of some exotic flowers present in Brazil such as Amaranthus hypochondriacus, Tropaeolum majus (red), Tropaeolum majus (orange) and Spilanthes oleracea L. The content of total phenolic compounds, flavonoids, condensed, hydrolysable tannins and antioxidante capacity were determined. The identification...
