- The present communication reports the isolation and identification of four triterpenoid saponins from the chloroform extract of the leaves of Tocoyena brasiliensis: 3-O-β-D-quinovopyranosyl quinovic acid, 3-O-β-D- quinovopyranosyl cincholic acid, 3-O-β-D-glucopyranosyl quinovic acid and the 28-O-β-D-glucopyranosyl ester derivative of quinovic acid as binary mixtures, respectively. From the ethanol extract a flavonoid identified as ramnazin-3-O-rutinoside was obtained. The structures of these compounds were assigned by data analysis of ID and 2D NMR spectrometry and comparison with data recorded in the literature for these compounds.
