New terpenoid coumarins from Ferula tadshikorum
Two new terpenoid coumarins — tadzhiferin (I) and tadzhikorin (II) — have been isolated from the fruit ofFerula tadshikorum M. Pimen.
On the basis of physicochemical and spectral investigations, the structure of 7-(9′-hydroxy-3′,7′,11′-trimethyldodeca-2′,6′,10′-trienyloxy)coumarin is proposed for (I) and that of 7-(4′-acetoxy-9′-hydroxy-3′,7′,11′-trimethyldodeca-2′,6′,10′-trienyloxy)coumarin for (II).
