THE COUMARIN COMPOSITION OF Seseli tortuosum

Article abstract of DOI:10.1007/BF00575164

The results are given of the identification of the known pyranocoumarin campestrinol (I), and the structures of four new coumarin derivatives have been studied - tortuosin (II), tortuosinin (III), tortuosinol (IV), and tortuosidin (V).On the basis of their spectral characteristics and chemical transformations, the corresponding structures have been established for compounds (II)-(V).
