| Abstract: | During the investigation of the glycosidic constitutents of Calendula arvensis L. we isolated the previously reported Arvensoside A, Arvensoside B, Calenduloside C and Calenduloside D. The complete assignment 1H NMR spectra of these compounds was achieved through the concerted application of 2D-homonuclear chemical shift correlations. Calenduloside C and Calenduloside D were isolated for the first time from the fresh aerial parts of Calendula arvensis L. |
