Furocoumarins ofCnidium dubium
1. Paper chromatography has shown that the fruit ofC. dubium contains not less than eight substances of coumarinic nature; six of these (A, B, C, D, E, and H) have been isolated in the crystalline state.
2. Substances B, D, and E are identical with isoimperatorin, imperatorin, and oxypeucedanin, respectively. Some properties of substance H have been determined. Prangenin [F] has been detected in the fruit ofC. dubium by paper chromatography.
3. The structure of two new compounds has been established: substance A (cnidicin) (I) is 5, 8-di-(γ, γ-dimethylallyloxy) psoralen, and substance C (cnidilin) (II) is 5-(γ, γ-dimethylallyloxy)-8-methoxypsoralen.
