Extração de compostos bioativos de cascas e sementes de pitomba (Talisia esculenta) utilizando solventes eutéticos

Abstract

The interest in discovering plant extracts with different biological activities has increased a lot in recent years because of the search for a healthy lifestyle and the assessment that certain foods have substances that bring desirable physiological effects and are beneficial to health. The present work aimed to use pitomba bark and seed to obtain a natural extract with high antioxidant capacity from the extraction technique with eutectic solvents, through agitation and temperature. Observing the relationship between the two types of pitomba residues (peel and seed), higher values of phenolic compounds were obtained with the combination of L-proline with levulinic acid (0.01246 mgEAG.g -1 ) and choline chloride with glycerol (0.05641 mgEAG.g -1 ), without showing significant differences. For flavonoids, the highest value was observed with L-proline and levulinic acid (2.7058 mgEQ.g -1 ). In the DPPH and FRAP analyses, the best combination observed in both was choline chloride with glycerol for DPPH and choline chloride with glycerol and L-proline with levulinic acid for FRAP, respectively. From the results of this study, it was possible to observe that the residues present significant values in compounds of interest for application in the food and drug industry.
