Zusammenfassung: | ABSTRACT This study aimed to quantify polyphenolic compounds and antioxidant activity of four fruits native to the coast of Ceara under different maturation stages aiming their use for a healthier diet. Myrtle (Eugenia punicifolia (Kunth) DC.) fruits were collected at the Botanical State Park of Ceara, in Caucaia-CE and guajiru (Chrisobalanus icaco L.), manipuça (Mouriri cearensis Huber) and murici-pitanga (Byrsonima gardneriana A. Juss.) fruits were collected at the Botanical Garden of São Gonçalo, São Gonçalo do Amarante-CE. Fruits were collected and transported to the Laboratory of Plant Ecophysiology, being characterized, processed and frozen for chemical assessments at the Laboratory of Physiology and Postharvest Technology - Embrapa Agroindústria Tropical: polyphenolic compounds and total antioxidant activity. The ESTAT software was used for statistical analyses. The polyphenolic content had the highest and the lowest value for guajiru fruits with 480.73 and 10.90 mg/100 g, respectively and total antioxidant activity, the highest value was found for manipuça fruits, with 42.99 µM of Trolox/g of pulp and the lowest value for guajiru fruits, with 1.45 µM of Trolox/g of pulp. There was a significant correlation between polyphenolic content and total antioxidant activity obtained for guajiru fruits, which showed high correlation coefficient, R = -0.95 (P < 0.05).
RESUMO A presente pesquisa objetivou quantificar os compostos polifenólicos e a atividade antioxidante de quatro frutas nativas do litoral cearense, em diferentes estádios de maturação, visando a sua utilização para uma alimentação mais saudável. Os frutos da murta (Eugenia punicifolia (Kunth) DC.) foram colhidos no Parque Estadual Botânico do Ceará, em Caucaia-CE, e os do guajiru ( L.), do Chrisobalanus icacomanipuçá (Mouriri cearensis Huber) e do murici-pitanga (Byrsonima gardneriana A. Juss.), no Jardim Botânico de São Gonçalo, em São Gonçalo do Amarante–CE. Os frutos foram coletados e transportados ao Laboratório de Ecofisiologia Vegetal, sendo caracterizados, depois processados e congelados para as avaliações químicas, no Laboratório de Fisiologia e Tecnologia Pós-Colheita, da Embrapa Agroindústria Tropical: compostos polifenólicos e atividade antioxidante total. Utilizou-se o programa ESTAT nas análises estatísticas. O teor de polifenólicos teve o maior e o menor valor para o fruto de guajiru, com 480,73 e 10,90 mg/100 g, respectivamente, e à atividade antioxidante total, o maior valor foi |
