Plant metabolites. New compounds and anti-inflammatory activity of Uncaria tomentosa

J Nat Prod. 1991 Mar-Apr;54(2):453-9. doi: 10.1021/np50074a016.


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.
