Copyright policy )Coumarins IX: Coumarins of Sphenosciadium Capitellatum (A. Gray)
The aliphatic naphtha extract of the roots of Sphenosciadium capitellatum (A. Gray) has yielded isoimperatorin, phellopterin, imperatorin, oxypeucedanin, isopimpinellin, and a linear furanocoumarin, C17H16O5, which has been assigned the 5-γ,γ-dimethylallyloxy-8-methoxy psoralen structure on the basis of degradative and spectral studies. This linear furanocoumarin appears to be identical to cnidilin, recently isolated and characterized from Cnidium dubium (Schkuhr) Thell. The methanol extract yielded sucrose and the glycosidic coumarin, nodakenin, in excellent yield.
