dc.description.abstract El aislamiento químico de un extracto semipurificado de las semillas de guaraná, Paullinia cupana H.B.K. var. sorbilis (Mart.) Ducke, resultó en la identificación de cafeína, catequina, epicatequina y procianidinas B2, B3 y B4. La actividad antibacteriana de los extractos y de las substancias se evaluó in vitro contra Staphylococcus aureus, Bacillus subtilis, Escherichia coli y Pseudomonas aeruginosa. En concentraciones hasta 1000 µg/ml ninguna actividad fue demostrada frente a dichos microorganismos. es
