Abstract 2D NMR‐derived 1 H and 13 C NMR signal assignments of six structurally closely related cucurbitacin derivatives are presented. The investigated 2‐ O ‐β‐ 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 Copyright © 2005 John Wiley & Sons, Ltd.
