A new triterpenoid saponin, coumoside A, has been isolated from the whole plant of Cyclamen coum and the structure of this novel saponin (C58H92O27) has been deduced by NMR methods based on H-1, C-13, DEPT, H-1-H-1 COSY, HETCOR, NOESY-NMR experiments and the FAB-mass spectrum. It has the structure 3 beta-O-{beta-D-glucopyranosyl-(1-6)-[alpha-L-arabinopyranosyl-(1-2)]-beta-D-glucopyranosyl-(1-4)-[beta-D-glucopyranosyl-(1-2)1-2]-alpha-L-arabinopyranosyl}-16 alpha-hydroxy-30,28 beta-lactone-olean-12-ene and is called coumoside A (C) 1998 Elsevier Science Ltd.
