Guarana is a plant native to the Amazon, and its seeds are used as soft drinks other energy drink ingredients. The phytochemical aspects of guarana have been extensively explored for use in herbal cosmetic compositions due presence metabolites, such methylxanthines polyphenols. This work aims fill gap information about accumulation polyphenols leaves fruits cultivars. Thus, will be generated contribute future studies on genetic improvement physiology. Methylxanthines (caffeine [Cf], theobromine [Tb], theophylline [Tf]) phenolic compounds (catechin [Ct] epicatechin [EC]) were quantified by HPLC (pericarp seed) eighteen Tf was not detected any tissue. Caffeine present almost exclusively (4.21 ± 0.69 g.100g dry weight-1), while predominant leaves. Although catechin both tissues, their contents higher seeds, with mean values 1.36 0.76 weight-1, respectively. In cultivars under study, BRS-Satere BRS-608 stood out high caffeine seeds. On hand, BRS-Luzeia cultivar, highest observed results provide new perspectives commercial exploitation which could favor industry, since main source these
