1H and 13C NMR chemical shifts are reported for five anthraquinone glycosides from Rhamnus frangula (Alder Buckthorn). The investigation utilized data obtained by a variety of 1D and 2D NMR techniques such as homodecoupling, NOE, J-modulated spin-echo, COSY, HSC and COLOC. Assignments were made for frangulin A and B and glucofrangulin A and B. A further compound previously thought to be a glycoside of emodin is shown to be physcion-8-O-β-D-glucoside. © 1998 John Wiley & Sons, Ltd. |
