Abstract

Two new sesquiterpene-coumarin conjugates designated foetidin acetate and foetidone were isolated from the roots of Ferula marmarica. The structures of the sesquiterpene-coumarins have been fully characterized by spectroscopic methods, among which foetidin acetate was confirmed by single-crystal X-Ray crystallography. Absolute configuration of both new compounds was established by CD.
