从唐古特青兰（Dracocephalum tanguticum）中分离得到四个新的精脒苷类化合物，命名为Dracotanosides A-D（1-4）。这些分子代表了来自该植物属的第一个亚精胺糖苷。通过光谱和化学方法确定了其结构，包括绝对构型。用密度泛函理论计算了糖苷配基1a的酰胺键转动势垒。
Four new spermidine glycosides, dracotanosides A-D (1-4), have been isolated from Dracocephalum tanguticum. These molecules represent the first spermidine glycosides from this plant genus. The structures, including absolute configurations, were determined by spectroscopic and chemical methods. The amide bond rotational barrier of aglycone 1a was calculated by density functional theory (DFT) computation.
