A triterpenoid saponin from Cyclamen coum.
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 1H, 13C, DEPT, 1H-1H 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)]-alpha-L -arabinopyranosyl]-16 alpha-hydroxy-30,28 beta-lactone-olean-12-ene and is called coumoside.
