ABSTRACT - The objective of this study was to determine and correlate the extraction yields, antioxidant activity, total phenolics and total flavonoids from grape, mango and peanut agro-industrial by-products. The &#x3B2;-carotene/linoleic acid autoxidation system and scavenging capacity for DPPH and ABTS free radicals assays were used. The results were expressed in terms of lyophilized sample or dry extract. Mango bagasse exhibited the highest extraction yield (37.07%) followed by peanut skin (15.17%) and grape marc (7.92%). In terms of lyophilized sample, total phenolics did not vary significantly among the residues evaluated (average of 60.33mg EAG g-1); however, when they were expressed as dry extract grape marc exhibited the highest total phenolic (768.56&#xB1;116.35mg GAE g-1), followed by peanut skin (404.40&#xB1;13.22mg GAE g-1) and mango bagasse (160.25&#xB1;4.52mg GAE g-1), Peanut skin exhibited the highest content of total flavonoids (2.44mg QE g-1), while grape marc (1.76mg QE g-1) and mango bagasse (1.70 mgQE g-1) showed no significant differences. The extraction yield showed strong negative linear correlation with total phenolic and total flavonoid. This study showed that peanut skin was the sample with the highest antioxidant activity and it was strongly influenced by total flavonoids. All extracts of byproducts showed antioxidant activity comparable to &#x3B1;-tocopherol, and they can be a source of natural compounds with potential to replace synthetic antioxidants such as BHT.

Key words: total phenolics, total flavonoids, ethanolic extraction</subfield>

RESUMO - O objetivo deste estudo foi determinar e correlacionar os rendimentos de extra&#xE7;&#xE3;o, atividade antioxidante, compostos fen&#xF3;licos totais e flavonoides de subprodutos agroindustriais de uva, manga e amendoim. A autoxida&#xE7;&#xE3;o do sistema &#x3B2;-caroteno/&#xE1;cido linoleico e a capacidade de sequestro dos radicais DPPH e ABTS foram os ensaios antioxidantes utilizados. Os resultados foram expressos com base na amostra liofilizada ou no extrato seco. O baga&#xE7;o de manga apresentou o maior rendimento de extra&#xE7;&#xE3;o (37,07%) seguido da pel&#xED;cula de amendoim (15,17%) e baga&#xE7;o de uva (7,92%). Em termos de amostra liofilizada, o teor de fen&#xF3;licos totais n&#xE3;o variou significativamente entre os res&#xED;duos avaliados (m&#xE9;dia de 60,33mg EAG g-1), entretanto, quando foi expresso com base no extrato seco, o baga&#xE7;o de uva exibiu o maior teor de fen&#xF3;licos totais (768,56&#xB1;116,35mg EAG g-1), seguido da pel&#xED;cula de amendoim (404,40&#xB1;13,22mg EAG g-1) e baga&#xE7;o de manga (160,25&#xB1;4,52 mg EAG g-1). Apel&#xED;cula de amendoim apresentou o maior conte&#xFA;do de flavonoides totais (2,44mg EQ g-1), enquanto os baga&#xE7;os de uva (1,76mg EQ g-1) e de manga (1,70mg EQg-1) n&#xE3;o mostraram diferen&#xE7;as significativas. O rendimento de extra&#xE7;&#xE3;o mostrou fortes correla&#xE7;&#xF5;es lineares negativas como teor de fen&#xF3;licos totais e flavonoides totais. Este estudo mostrou que a pel&#xED;culade amendoim foi o material que apresentou a maior atividade antioxidante e isso foi fortemente influenciado por flavonoides totais. Os extratos avaliados mostraram atividade antioxidante compar&#xE1;vel &#xE0; do &#x3B1;-tocoferol, com potencial para substituir antioxidantes sint&#xE9;ticos, tais como o BHT.

Palavras-chave: fen&#xF3;licos totais, flavonoides, extra&#xE7;&#xE3;o etan&#xF3;lica. </subfield>
