From the tubers of Cyclamen coum (Primulaceae) three new saponins, cyclaminorin (1), cyclacoumin (3) and mirabilin lactone (4) were isolated together with a known saponin, deglucocyclamin (2). The structures of the new compounds were established as 13 beta,28-epoxy-3 beta-(([beta-D-glucopyranosyl-(1-->2)]- [beta-D-glucopyranosyl-(1-->4)]-alpha-L-arabinopyranosyl) oxy) 16 alpha-hydroxy-olean-30-al (1), 13 beta,28-epoxy-3 beta-((([beta-D-xylopyranosyl-(1-->2) -beta-D-glucopyranosyl-(1-->4)]-[beta-D-glucopyranosyl-(1-->2)]- alpha-L-arabinopyranosyl)oxy)-16 alpha,23-dihydroxy-olean-30-al (3) and 16 alpha-hydroxy-3 beta-((([beta-D-xylopyranosyl-(1-->2)]- [beta-D-glucopyranosyl-1-->6)]-beta D-glucopyranosyl-(1-->4))- [beta-D-glucopyranosyl-(1-->2)]-alpha-L-arabinopyranosyl)-oxy) olean-12-eno-30,28-lactone (4). Structure elucidattions were accomplished using both spectral (NMR, MS, IR) and chemical methods.
从仙客来（报春花科）的块茎中分离出三种新的皂苷，即仙客来苷元（1）、环阿糖精（3）和奇异内酯（4），以及一种已知的皂苷，去葡萄糖环阿糖精（2）。新化合物的结构确定为13β,28 - 环氧 - 3β - （[β - D - 吡喃葡萄糖基 - （1→2）] - [β - D - 吡喃葡萄糖基 - （1→4）] - α - L - 阿拉伯吡喃糖基）氧基 - 16α - 羟基 - 齐墩果 - 30 - 醛（1）、13β,28 - 环氧 - 3β - （（[β - D - 吡喃木糖基 - （1→2） - β - D - 吡喃葡萄糖基 - （1→4）] - [β - D - 吡喃葡萄糖基 - （1→2）] - α - L - 阿拉伯吡喃糖基）氧基） - 16α,23 - 二羟基 - 齐墩果 - 30 - 醛（3）和16α - 羟基 - 3β - （（[β - D - 吡喃木糖基 - （1→2）] - [β - D - 吡喃葡萄糖基 - 1→6）] - β - D - 吡喃葡萄糖基 - （1→4）） - [β - D - 吡喃葡萄糖基 - （1→2）] - α - L - 阿拉伯吡喃糖基）氧基 - 齐墩果 - 12 - 烯 - 30,28 - 内酯（4）。结构解析采用光谱（NMR、MS、IR）和化学方法完成。
