Eupatoriopicrin 19-O-Linolenoate and Other Constituents from Eupatorium cannabium

Abstract

The investigation of the roots and aerial parts of Eupatorium cannabium afforded, in addition to the sesquiterpene lactones eupatolide, eupatoriopicrin, and eucannabinolide isolated previously, eight further lactones, three of which are new. Furthermore, in addition to known compounds, a new clerodane derivative and two further tremetone derivatives as well as 10-acetoxyneryl acetate were isolated.
