Abstract:
The petroleum ether (PE) extract from Ixeris chinensis was submitted to chromatographic separation. A new sesquiterpene, namely 14-noreudesma-3-hydroxy-3-en-2,9-dione, was isolated from the PE extract. The structures of the sesquiterpene was elucidated by using spectroscopic methods, including UV, IR, HR-ESI-MS and extensive 1D and 2D NMR techniques.
