Abstract

Bioassay-directed fractionation of the anti-inflammatory extracts of Uncaria tomentosa, using the carrageenan-induced edema in rat paw, has led to the isolation of a new quinovic acid glycoside 7 as one of the active principles. Furthermore, a new triterpene 8 was isolated as its methyl ester. The structures were elucidated by spectral and chemical studies.
