The Authors have studied the biosynthesis of O–alkylfurocoumarins present in the green
plants of Angelica archangelica, administering marmesin, rutaretin and successively also psoralen. While marmesin has
been efficaciously incorporated in the isolated O–alkylfurocoumatfins, rutaretin (8–hydroxymarmesin)
was not utilized by the plant, Psoralen on the other hand was effectively incorporated
into O–alkylfurocoumarins.
The data seem to indicate that the biosynthesis of O–alkylfurocoumarins derives in
this plant from hydroxylation of psoralen and successive alkylation.
