Summary
Four compounds (I–IV) of coumarin nature have been isolated from a methaolic extract of the roots ofPrangos ferulacea (L.) Lindl.
A study of IR, NMR, and mass spectra, and also chemical properties, has shown that (I) is 8-(2′-acetoxy-3′-hydroxyisopentyl)-7-methoxycoumarin, identical with the monoacetyl derivative of meranzin hydrate; this is the first time it has been found in nature. The investigation of the structure of compounds (II–IV) is continuing.
