- THE STEREOSTRUCTURE OF WENJINE AND RELATED (1S,10S),(4S,5S)-GERMACRONE-1(10),4-DIEPOXIDE ISOLATED FROM CURCUMA WENYUJIN
-
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. KEYWORDS - Curcuma wenyujin; wenjine; (1S,10S),(4S,5S)-germacrone-1(10),4-diepoxide; (4S,5S)-germacrone-4,5-epoxide; X-ray diffraction; peroxy hemiacetal; 1,2-dioxalane
