Resumo: The phytochemical investigation of Guettarda pohliana roots led to the isolation of 28-O-beta-D-glycopyranosyl-3-O-beta-D-quinovopyranosyl quinovic acid, 28-O-beta-D-glycopyranosyl-3-O-beta-D-glycopyranosyl quinovic acid, 3-O-beta-D-glycopyranosyl quinovic acid, 28-O-beta-D-glycopyranosyl-3-O-beta-D-glycopyranosyl cincholic acid along with quinovic acid, daucosterol and 4,5-O-dicaffeoyl quinic acid. The structures of the isolated compounds were assigned on the basis of spectroscopic data, including two-dimensional NMR methods. The antiradical activity of the crude methanolic extract and of its fractions was evaluated.
