摘要

Two novel sesquiterpene dimers, achillinin B and C, were isolated from the flowers of Achillea millefolium. The structures were elucidated by extensive spectroscopic analysis. A plausible biosynthetic pathway of achillinin B and C by Diels-Alder reaction of the corresponding guaiane sesquiterpenoids is also discussed.
