Abstract A new triterpenoid saponin, primulanin, isolated from the whole plant of Primuladenticulata was characterized as 3- O [β- d -xylopyranosyl-(1 → 2)-β- d -glucopyranosyl-(1 → 4)-α- l -arabinopyranosyloxy]-16α-hydroxy-13β,28-epoxy-olean-30-al.

Saponins in Cyclamen species: Configuration of cyclamiretin C and structure of isocyclamin
Abstract 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 -glu
摘要 在细胞学上确定的 14 种仙客来球茎中鉴定出 5 种皂苷元和 3 种皂苷,并通过质谱、1H 和 13C NMR 光谱法确定了它们的结构。除了已知的水解产物外,还发现了报春花苷 A,并且证明环米苷元 C 与环孢霉素 C 相同。新的皂苷异环胺被鉴定为 3β-O-β-d-吡喃葡萄糖基-(1-6)- [O-β-d-吡喃木糖基-(1-2)]-O-β-d-吡喃葡萄糖基-(1-4)-[O-β-d-吡喃葡萄糖基-(1-2)]-α-l-阿拉伯吡喃糖基}-16α-羟基-13β, 28-epoxy-olean-30-al。
