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