Abstract:
A new chloro-pseudoguaianolide-type sesquiterpene lactone, 11β-hydroxy-13-chloro-11,13-dihydrohymenin (1), was isolated from the Egyptian medicinal plant Ambrosia maritima. The structure was determined by spectroscopic methods, particularly high-resolution 1H, 13C-NMR and 2D 1H–1H and 1H–13C COSY NMR analysis.
Keywords:Ambrosia maritima   Sesquiterpene lactones   11β  -Hydroxy-13-chloro-11,13-dihydrohymenin
