Grain germination changes the profile of phenolic compounds and benzoxazinoids in wheat: a study on hard and soft cultivars. Repositório Alice
BARANZELLI, J.; SOMACAL, S.; MONTEIRO, C. S.; MELLO, R. de O.; RODRIGUES, E.; PRESTES, O. D.; LÓPEZ-RUIZ, R.; FRENICH, A. G.; ROMERO-GONZÁLEZ, R.; MIRANDA, M. Z. de; EMANUELLI, T..
Abstract: Pre-harvest sprouting is a frequent problem for wheat culture that can be simulated by laboratory-based germination. Despite reducing baking properties, wheat sprouting has been shown to increase the bioavailability of some nutrients. It was investigated whether wheat cultivars bearing distinct grain texture characteristics (BRS Guaraim, soft vs. BRS Marcante, hard texture) would have different behavior in terms of the changes in phytochemical compounds during germination. Using LC-Q-TOF-MS, higher contents of benzoxazinoids and flavonoids were found in the hard cultivar than in the soft one. Free phytochemicals, mainly benzoxazinoids, increased during germination in both cultivars. Before germination, soft and hard cultivars had a similar...

Natural deep eutectic solvent (NADES): A strategy to improve the bioavailability of blueberry phenolic compounds in a ready-to-use extract. Repositório Alice
SILVA, D. T. da; SMANIOTTO, F. A.; COSTA, I. F.; BARANZELLI, J.; MULLER, A.; SOMACAL, S.; MONTEIRO, C. S.; VIZZOTTO, M.; RODRIGUES, E.; BARCIA, M. T.; EMANUELLI, T..
This study investigated whether a ready-to-use extract obtained using a natural deep eutectic solvent (NADES) affects the pharmacokinetic profile of blueberry phenolic compounds compared to organic solvent (SORG)-extracted compounds. SORG extract was administered as an aqueous solution after solvent removal. Wistar rats received a single dose of crude extract of blueberry obtained using NADES (CE-NADES) or SORG (CE-SORG), followed by LC-DAD-MS/MS analysis of blood and cecal feces. Non-compartmental pharmacokinetic analysis revealed that CE-NADES increased the bioavailability of anthocyanins by 140% compared to CE-SORG. CE-NADES increased the stability of phenolic compounds during in vitro digestion by delaying gastric chyme neutralization. These results...

Natural deep eutectic solvent (NADES)-based blueberry extracts protect against ethanol-induced gastric ulcer in rats. Repositório Alice
SILVA, D. T. da; RODRIGUES, R. F.; MACHADO, N. M.; MAURER, L. H.; FERREIRA, L. F.; SOMACAL, S.; VEIGA, M. L. da; ROCHA, M. I. de U. M. da; VIZZOTTO, M.; RODRIGUES, E.; BARCIA, M. T.; EMANUELLI, T..
Blueberry is a polyphenol-rich fruit bearing great bioactive potential. Natural deep eutectic solvents (NADES) emerged as putatively biocompatible solvents that could substitute for toxic organic solvents in the extraction of fruit phenolic compounds for developing nutraceuticals or functional foods. Therefore, the aim of this study was to investigate the gastroprotective effects and the biocompatibility of a blueberry crude extract (CE) obtained using NADES and of the extract fractions (anthocyanin-rich fraction ? ARF; non-anthocyanin phenolic fraction - NAPF) in a model of ethanol-induced gastric ulcer in rats. CE was the NADES-containing, ready-to-use extract that was obtained using choline chloride:glycerol:citric acid NADES (0.5:2:0.5 M ratio). ARF...
