Badrakemonin, a New Eremophilane-Type Sesquiterpene from the Roots of Ferula badrakema Kos.-Pol.

Phytochemical investigation of the dichloromethane extract of the dried roots of Ferula badrakema resulted in the identification of one new and six known compounds. Known compounds were sesquiterpene coumarins: mogoltacin, feselol, badrakemin acetate, ferocaulidin, conferone and conferol acetate. The new compound was a sesquiterpene, named badrakemonin. The structures of these compounds were elucidated by extensive NMR spectroscopic methods including 1D-(1H and 13C) and 2D-NMR (HSQC, HMBC, and ROESY) as well as MS experiments.
