Title A name given to the resource Atividade antioxidante e teor de fenólicos totais em hortaliças orgânicas e convencionais Antioxidant activity and phenolic content in organic and conventional vegetables Creator An entity primarily responsible for making the resource Kettelin Aparecida Arbos, Renato João Sossela de Freitas, Sônia Cachoeira Stertz, Marlos Ferreira Dornas Description An account of the resource Considerando que os consumidores estão mais conscientes com a sua saúde e mais preocupados com as condições ambientais, verifica-se uma crescente demanda por alimentos orgânicos. O objetivo deste estudo foi comparar a atividade antioxidante e o teor de fenólicos totais entre alface, rúcula e almeirão de cultivos orgânico e convencional, plantados em uma mesma horta. A atividade antioxidante dos extratos metanólicos das hortaliças foi determinada através do ensaio do DPPH. O teor de fenólicos totais foi obtido espectrofotometricamente de acordo com o método de Folin-Ciocalteu e calculado como equivalente de ácido gálico. A atividade antioxidante contra o radical livre DPPH foi: rúcula orgânica > almeirão orgânico > alface orgânica > rúcula convencional > almeirão convencional > alface convencional. O teor de fenólicos totais foi superior nos vegetais orgânicos. Os resultados deste estudo sugerem que as hortaliças orgânicas podem ser uma importante fonte de antioxidantes naturais e de compostos fenólicos e, portanto, seu consumo deve ser estimulado.Considering that consumers are becoming more conscious of their health and more concerned with environmental conditions, there has been an increasing demand for organic foods. The aim of this study was to compare the antioxidant activity and determine the total phenolic content of organic and conventional cultivations of lettuce, arugula, and chicory grown in the same vegetable garden. The antioxidant activity of the methanol extracts of these leaf vegetables wasdetermined using DPPH free radical scavenging assay. The total phenolic content in the extracts was determined spectrometrically according to the Folin-Ciocalteu method and calculated as equivalent of gallic acid. The antioxidant activity against the DPPH free radical was: organic arugula> organic chicory > organic lettuce > conventional arugula > conventional chicory > conventional lettuce. The total phenolic content was higher in the organic vegetables. The results of this study suggest that the organic vegetable can be a good dietary source of natural antioxidant and phenolic compounds; therefore, their consumption must be encouraged.
