Five sapogenins and three saponins were identified in bulbs of 14 cytologically defined Cyclamen species and their structures were determined by means of mass, ¹H and ¹³C NMR spectroscopy. In addition to the known products of hydrolysis, primulagenin A was found, and cyclamiretin C was shown to be identical with cyclamigenin C. The new saponin isocyclamin was identified as 3β-{O-β-D-glucopyranosyl-(1→6)-[O-β-D-xylopyranosyl-(1→2)]-O-β-D-glucopyranosyl-(1→4)-[O-β-D-glucopyranosyl-(1→2)]-α-L-arabinopyranosyl}-16α-hydroxy-13β,28-epoxy-olean-30-al.
