1H AND 13C NMR SPECTRA AND THE STRUCTURE OF A NEW COUMARIN, C-GLYCOSIDE DAUROSIDE D, FROM Haplophyllum dauricum

Article abstract of DOI:10.1007/BF00575694

On the basis of chemical transformation, 1H and 13C NMR spectra, tha structure of dauroside D isolated from Haplophyllum dauricum has been established as 6-C-β-D-glucopyranosyl-5,7-dihydroxycoumarin.Some interesting features of the 1H NMR spectra of its acetate have reported and an assignment of the signals in its 1H and 13C NMR spectra has been made.Dauroside D is the first natural coumarin C-glycoside.
