Abstract

Eight undescribed sesquiterpenes, including three dimeric guaianolides and five sesquiterpens, together with ten known ones, were isolated from the aerial parts of Artemisia sieversiana. Their structures were elucidated by extensive spectroscopic techniques and ECD calculation. The isolated compounds were tested for their anti-inflammatory effects against IL-1β, IL-6 and TNF-α in LPS-induced RAW 264.7 cells. Compounds 4, 9, 12, 15, 16 and 17 showed potent anti-inflammatory activities.

Keywords: Anti-inflammatory; Artemisia sieversiana; Dimeric guaianolides; Sesquiterpenes.
