Abstract
A new eremophilane sesquiterpene was isolated from the MeOH extract of the aerial parts of Senecio nemorensis. Its structure was established as 11-hydroxy-1β-methoxyl-8-oxoeremophila-6,9-dien-12-oic methyl ester by extensive application of spectroscopic methods, including IR, EI-MS, HR-ESI-MS, 1D and 2D NMR spectroscopy.
