GRAPHICAL ABSTRACT

ABSTRACT

A previously undescribed sesquiterpene lactone, named eupalinolide N (1), was isolated from traditional Chinese medicine “Ye-Ma-Zhui” (Eupatorium lindleyanum) by ethanol reflux extraction, reduced pressure concentration, macroporous resin column chromatography, and C18 reversed-phase chromatography. Its structure was elucidated by a comprehensive interpretation of spectroscopy evidence as well as ECD calculations. 1 showed anti-inflammatory activity by inhibiting the gene expressions of pro-inflammatory factors including IL-1β, TNFα COX-2, and iNOS at the concentration of 7.5 μM, as well as attenuating the excretion of NO, IL-6, and TNF-α in Raw 264.7 macrophages at the concentration of 15 μM.
