In this study were determined the polyphenols contents of agricultural residues - stem and leaf - of pineapple plants (Ananas comosus (L.) Merrill) from the cultivars Pérola, Perolera, Smooth Cayenne and Primavera, grown in Ijací, MG, with the purpose of giving information on the possible use of these residues as human and/or animal food. The cultivars studied did not present polyphenols contents above 1%, level considered high and harmful to the protein digestibility. The leaves presented polyphenols contents higher than stems in all cultivars analysed. There were no significant differences among cultivars, but Smooth Cayenne had the highest polyphenols contents and Perolera the lowest.
