Seventeen daucane esters have been isolated from the seeds of Ferula hermonis Boiss (Apiaceae). Three of these sesquiterpenes, 4β-hydroxy-6α-benzoyl-7-daucen-9-one (1), 4β, 8β-dihydroxy-6α-benzoyl-dauc-9-ene (2), and 4β, 9α-dihydroxy-6α-benzoyl-dauc-7-ene (4), named feruhermonins A-C, respectively, are novel natural products. The structures of these compounds were elucidated unequivocally by a series of 1D and 2D NMR analyses. Although 4β, 8β-dihydroxy-6α-(4-hydroxy-3-methoxybenzoyl)-dauc-9-ene (3) was reported previously, the complete spectroscopic data for this compound are presented here for the first time.
