Abstract
Two new sesquiterpene dimers, lappadimers A and B, were isolated from the roots of Saussurea lappa (Yunmuxiang). Their structures were established on the basis of spectroscopic methods. They were found to have potential anti-inflammatory activity at 10 µM and could reduce LPS-induced NO levels in murine macrophage, with inhibitory rates of 67% and 47%, respectively.
