SAPONINS IN CYCLAMEN SPECIES: CONFIGURATION OF CYCLAMIRETIN C AND STRUCTURE OF ISOCYCLAMIN

Article abstract of DOI:10.1016/0031-9422(89)80123-2

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-(1-4)--α-L-arabinopyranosyl>-16α-hydroxy-13β,28-epoxy-olean-30-al. - Key Word Index - Cyclamen; Primulaceae; saponin; sapogenin; chemotaxonomy.
