摘要：

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. Copyright (C) 1997 Published by Elsevier Science Ltd. All rights reserved.
