Abstract The investigation of Asterumbellatus afforded six new eudesmanolides and a new selina-triene and from Aster exilis a new tremetone derivative was isolated. The structures were elucidated by spectroscopic methods and by some chemical transformations. The chemotaxonomic situation is discussed briefly.
