Six volatile compounds, curdione (1), curcumol (2), germacrone (3), curzerene (4), 1,8-cineole (5) and beta-elemene (6), were successfully isolated from the essential oil of Curcuma wenyujin by high-performance centrifugal partition chromatography using a nonaqueous two-phase solvent system consisting of petroleum ether-acetonitrile-acetone (4:3:1 v/v/v). A total of 8 mg of curdione (1), 4 mg of curcumol (2), 10 mg of germacrone (3), 18 mg of curzerene (4), 9 mg of 1,8-cineole (5) and 17 mg of beta-elemene (6) were isolated from the essential oil (300 mg) in 500 min. Their structures were determined by comparison of their retention times and MS data with those of the authentic samples as well as NMR spectroscopic analysis.
