Identificación preliminar de algunos constituyentes del tallo de Paullinia fuscescens (Sapindaceae) y actividad biológica

A subfraction α was obtained from stem methanol extract of Paullinia fuscescens, which presented a strong antibacterial activity against Gram positive and Gram negative species besides a strong cytotoxic effect against the crustacean Artemia salina sp.. From this subfraction was separate and identify a mixture of compounds by GC/MS. The compounds identified were 7-hexadecene, 1,2,2-Trimethyl-1-(p-tolyl)-cyclopentane and tetra-decanoic and hexadecanoic acids with their methyl esters. The biological activity by the crude extract and isolated subfraction might be associated with the presence of the compounds .identified .in .this .study
