EVALUATION OF TOTAL POLYPHENOLS AND ANTHOCYANINS CONTENTS INDIFFERENT GENOTYPES OF AÇAÍ.Rafaella de A. Mattietto1, Ana Vânia Carvalho1, M. do Socorro P. de Oliveira1, Anna Tsukui2,Tayná Caroline M. Veiga2. 1Embrapa Eastern Amazon - CPATU, Dr. Enéas Pinheiro sn, 66095-100 Belém, Pará, Brazil. 2Federal University of Pará, Belém, Pará, Brazil.Açaí (Euterpe oleracea) is a native fruit from the Brazilian Amazon, whose pulp has been widelymarketed in the world, mainly due to the presence of bioactive compounds, which gives afunctional appeal. Within a program of genetic improvement for the specie, factors such asproductivity, yield and survival on stable land were studied by Embrapa Eastern Amazon(Belém, Pará, Brazil) that developed the cultivar BRS Pará. This program now focused in aspecial market that aims the release of a cultivar with increased functional characteristics. Werecharacterized the total polyphenols, total and monomeric anthocyanins of eight açaí BRS Parágenotypes proceeding from the Germplasm Bank of  Embrapa. Total polyphenols weredetermined according to the Folin-Ciocalteu method and the results were expressed as g gallicacid equivalents/100g. Total and monomeric anthocyanins were determined using the pHdifferential method and the results were expressed as g cyanidin 3-glucoside/100g. The results(dry matter) indicated high levels of polyphenols with variation of 2565.19 ±40.77 a 5239.73 ±160.24 mg/100g and only three genotypes were significant different according TUKEY p≤0.05.For the total anthocyanins it was observed a significant difference at 95% for all genotypes(values ranging from 574.88± 1.05 to 2166.39± 3.77 mg/100g). Regarding the monomericanthocyanins, currently the most effective related to antioxidant and anti-inflammatoryproprieties, the values ranged from 165.38± 3.63 to 629.08± 4.79mg/100g being this variationnot significant among four genotypes studied. The variability presented for all the studiedcharacters, facilitates the selection of genotypes supporting the genetic improvement program.
