Guaraná (Paullinia cupana Kunth, Sapindaceae) is popularly used for a variety of therapeutic purposes, such as a stimulant of the nervous system in cases of physical or mental stress, an antidiarrheal, diuretic, antineuralgic agent, as well as febrifuge and painkiller to treat migraine. For centuries, guaraná seeds have been used by the tribe Saterê-Maué, indigenous natives of the Amazon Region, as a stimulant, remedie, beverage, and an antidote, among other purposes. Recently, in Western markets, the extract from the seeds of guaraná, is commonly used in high-energy foods and drinks and dietary supplements. However, a broad spectrum of medicinal activities is reported for P. cupana, ranging from stimulation of the central nervous system, in cases of physical or mental stress, to appetite suppression. It can also be used as an aphrodisiac and a treatment for impotence, as well as a medication to reduce fever, stimulate metabolism, induce antiplatelet, antioxidant and antibacterial activites. P. cupana has been used also in cosmetic preparations, and it has become a popular soft drink in Brazil. In the last two decades, guaraná has emerged as a key ingredient in various sports and high-energy drinks. Methylxanthines, including caffeine, cathechins, theophylline and theobromine, and tannins are compounds which are reported for this plant.

CONSTITUENTS: Guaraná seeds contain high amounts of methylxanthines and tannins, as well as saponins, starch, polysaccharides, pigments, fats and choline. The methylxanthines, specially caffeine, theophylline and theobromine, are found in different plant organs. The seeds of P. cupana are known to contain the highest natural dose of caffeine in the world (2 to 8%), some 3 to 5 times higher than that found in a Coffea arabica bean. Tannins are classified into condensed tannins, based on a flavonoid framework, and hydrolysable tannins, which are essentially galloyl esters of glucose. The total content of condensed tannins (procyanidins B1, B2, B3, B4, A2, and C1) in guaraná seeds has already been described in many papers. Other phenolic compounds found in guaraná seeds include epicatechin, catechin and ent-epicatechin, and these have been previously described. The seeds of guaraná also contain acylglycerols and cyanolipids, an unusual class of plant lipids restricted to only a few families.
