Eight transformed sesquiterpenes of germacrone by Mucor alternata were obtained. Their structures were characterized on the basis of spectral methods including 2D NMR. Among them, (1S, 4S, 55, 10R)-isozedoarondiol (2) and (1R, 4S, 55, 10R)-diepoxy-12-hydroxygermacrone (3) are new compounds. Copyright

A novel superoxidized sesquiterpenoid named wenjine (1) and germacrone diepoxide (2) with the germacrone epoxide (3) were isolated from the essential oil of the air-dried rhizoma of Curcuma wenyujin.The stereostructure of 1 was determined on the basis of its spectral data and X-ray diffraction.The absolute structure of 2 was also elucidated based on the spectral data and the transformation from 3.
