Özet

A new triterpenoid saponin, coumoside B, has been isolated from the whole plant of Cyclamen coum. The structure of the compound 3 (C58H92O27) has been deduced by NMR (400 MHz) methods based on the H-1,C-13, DEPT, H-1-H-1 COSY, HETCOR, NOESY-NMR experiments, and FAB-mass spectrum. Compound 3 was shown to have the structure 16 alpha-hydroxy-3 beta-{{[[beta-xyropyranosyl-(1 --> 2)]-[beta-glucopyranosyl-(1 --> 4)]-[beta-glucopyranosyl-(1 --> 2)]-alpha-arabinopyranosyl}-oxy}olean-12-eno-30,28-lactone and is named coumoside B.
