Methylxanthines and phenolic compounds in mate (Ilex paraguariensis St. Hil.) progenies grown in Brazil

Methylxanthines and phenolic compounds contents of 16 mate (Ilex paraguariensis St. Hil.) progenies from four Brazilian regions (Ivaí, Quedas do Iguaçu, Cascavel and Barão de Cotegipe) and those grown in three places within in the state of Paraná (Ivaí, Rio Azul and Guarapuava) were evaluated.
