The title compound: 2H-10,4a-(epoxy-methano)-phenantren-12-one-1,3,4,9,10,10a-hexahydro-5,6-dihydroxy-9 α-etoxy-1,1-dirnethyl-7-(1-methylethyl), was isolated from Salvia officinalis L. and Hyssopus officinalis L. C22H30O5, orthorhombic, P212121, (No. 19)a=8.309(1), b=11.320(2), c=22.060(3) Å, V=2075.0(9) Å3, Z=4, Dx=1.199 g·cm-3, λ(Cu Kα)=1.54184 Å, μ=6.43 cm-1, F(000)=808, T=296(1) K. The structure was solved by direct methods and refined to R=0.047 for 1824 observed reflections collected on a CAD-4 diffractometer. In the course of structure refinement conformational disorder of the isopropyl moiety and the terminal methyl group pertaining to the ethoxy ligand was established. They result altogether in four different conformers.
