(-)-1(10),11-Eremophiladien-9β-ol from the liverwort Marchantia polymorpha ssp. aquatica

A new eremophilane-type sesquiterpenoid, (-)-1(10),11-eremophiladien- 9β-ol, was isolated from the liverwort Marchantia polymorpha ssp. aquatica. Structure elucidation was performed by means of spectroscopic methods and chemical conversion to known eremophilone. The configuration was proved by NOE measurements and comparison of the products obtained by dehydration and hydrogenation of the alcohol with the hydrogenation products of both enantiomers of eremophilene and valencene by enantioselective gas chromatography with cyclodextrin derivatives.
