Abstract

The ^1^H and ^13^C NMR spectra of the anthraquinones physcion, emodin, chrysophanol, aloe‐emodin and rhein were assigned. The previously preferred assignments for C‐2 and C‐4 in physcion were reversed. The NOE technique was used for the assignment of the ^1^H signals and SEFT and/or heteronuclear decoupling for ^13^C resonances.
