Sesquiterpenoid and C14-polyacetylene glycosides from the rhizomes of Atractylodes lancea

Two new sesquiterpenoid glycosides with a eudesmane (1) and a guaiane carbon skeleton (2), respectively, and two new C14-polyacetylene glycosides (3, 4) were isolated from Atractylodes lancea. Their anti-inflammatory effects were evaluated by the LPS-induced NO production in microglia BV2 cells.
