Notes:
The complete assignment of all 1H and 13C NMR signals of acrihellin in chloroform solution is presented. The analysis of the 1H and 13C NMR spectra was performed using the heteronuclear 2D NMR techniques H,C-COSY and H,C-COLOC. For an unambiguous assignment of the 13C NMR spectrum the elucidation of carbon-carbon connectivities via 2D-INADEQUATE was most important. The INADEQUATE experiment was also applied to hellebrigenin in DMSO-d6 solution. This experiment confirmed a recently published carbon assignment.
