2D NMR-derived 1H and 13C NMR signal assignments of six structurally closely related cucurbitacin derivatives are presented. The investigated 2-O-beta-D-glucopyranosylcucurbitacins I, J, K, and L were obtained from Citrullus colocynthis (L.) Schrader whereas the aglyca cucurbitacin E and I were isolated from Ecballium elaterium L.
本文给出了六种结构密切相关的葫芦素衍生物的二维核磁共振氢谱（2D NMR）和碳谱（13C NMR）信号归属。所研究的2-O-β-D-吡喃葡萄糖基葫芦素I、J、K和L是从苦西瓜（Citrullus colocynthis (L.) Schrader）中获得的，而葫芦素E和I的苷元则是从喷瓜（Ecballium elaterium L.）中分离得到的。
