Nine novel prenyl-dihydrofurocoumarin-type sesquiterpenoid derivatives, 2, 3-dihydro-7-hydroxy-2R*, 3R*-dimethyl-2-[4, 8-dimethyl-3(E), 7-nonadienyl]-furo[3, 2-c]coumarin, 2, 3-dihydro-7-hydroxy-2S*, 3R*-dimethyl-2-[4, 8-dimethyl-3(E), 7-nonadien-6-onyl]-furo[3, 2-c]coumarin, 2, 3-dihydro-7-hydroxy-2S*, 3R*-dimethyl-2-[4-methyl-5-(4-methyl-2-furyl)-3(E)-pentenyl]-furo[3, 2-c]coumarin, 2, 3-dihydro-7-hydroxy-2R*, 3R*-dimethyl-2-[4-methyl-5-(4-methyl-2-furyl)-3(E)-pentenyl]-furo[3, 2-c]coumarin, 2, 3-dihydro-7-methoxy-2S*, 3R*-dimethyl-2-[4, 8-dimethyl-3(E), 7-nonadienyl]-furo[3, 2-c]coumarin, 2, 3-dihydro-7-methoxy-2R*, 3R*-dimethyl-2-[4, 8-dimethyl-3(E), 7-nonadienyl]-furo[3, 2-c]coumarin, 2, 3-dihydro-7-methoxy-2S*, 3R*-dimethyl-2-[4, 8-dimethyl-3(E), 7-nonadien-6-onyl]-furo-[3, 2-c]coumarin, and 2, 3-dihydro-7-methoxy-2S*, 3R*-dimethyl-2-[4-methyl-5-(4-methyl-2-furyl)-3(E)-pentenyl]-furo[3, 2-c]coumarin, were isolated from the roots of Ferula ferulioides. The structures were established by comprehensive spectral analysis. The biosynthetic pathway leading to these prenyl-furocoumarin-type sesquiterpenoids is proposed based on their structures.
