ResumoA new sesquiterpenoid coumarin, marmaricin, C24H30O4, was isolated from the roots of Ferula marmarica L., grown in Egypt. The carbon skeleton of the sesquiterpenoid moiety was identified by selenium dehydrogenation, yielding 1, 2, 5, 6-tetramethylnaphthalene. The coumarin moiety was determined by acid cleavage to give umbelliferone. The structure of marmaricin was assigned on the basis of spectral and chemical evidence.
