Abstract

A novel highly oxygenated sesquiterpenoid named wenjine (1) was isolated from Curcuma wenyujin. The relative structure was established on the basis of spectroscopic data and X-ray analysis. The absolute structure of 1 was determined by photooxygenation of (+)-(1S, 10S), (4S, 5S)-germacrone-1(10), 4-diepoxide (2).
