title: 1-(4a,8-Dimethyl-1,2,3,4,4a,5,6,8a-octa-hydro-naphthalen-2-yl)-3-(4-methyl-phen-yl)prop-2-en-1-one.
abstract: The title compound, C(22)H(28)O, was isolated from the aerial part of Inula viscosa- (L) Aiton [or Dittrichia viscosa- (L) Greuter]. The cyclo-hexene ring has a half-chair conformation, whereas the cyclo-hexane ring displays a chair conformation being substituted at position 2 by a 3-(4-methyl-phen-yl)prop-2-enoyl group. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds link mol-ecules into chains in the [010] direction.
