Abstract: Three new polyoxygenated triterpenes and six new quinovicacidglycosides have been isolated from Uncariatomentosa. The triterpenes are based on ursolic or quinovicacid structures; the glycosides have a C-3, a C-3,27 or a C-27 glycosylation pattern, and the sugar moietics are made up of one to three hexopyranoses (rhamnose, glucose, quinovose, galactose). Their structures were determined by spectral methods.
