    abstract = "The aerial parts of Centaurea thessala ssp. drakiensis afforded, in
addition to several known flavonoids and sesquiterpene lactones, a new
eudesmanolide. The structure of the compound was elucidated by
spectroscopic methods, particularly highfield NMR spectroscopy as 8
alpha-hydroxy-4-epi-sonchucarpolide."
