Isolation of the coumarin badrakemin from the roots ofFerula badrakema

Summary The roots of Ferula badrakema (K. Pol.) have yielded a coumarin badrakemin with the composition C₂₄H₃₀O₄, mp 198–199° C, []_D-64° (chloroform). The results of a chemical study and of UV, IR, and PMR spectroscopy have enabled us to propose structure I for badrakemin.Khimiya Prirodnykh Soedinenii, Vol. 3, No. 6, pp. 363–367, 1967
