In the paper by Ma et al., Cucurbitane-type triterpenoids from Momordica charantia. Planta Med 2010; 76: 1758–1761 [1], compound 1 was named momordicoside U (Fig. [1]). Unbeknown to the authors, the same name had been given earlier to a different substance in the article by Nguyen et al., Cucurbitane-type triterpene glycosides from the fruits of Momordica charantia. Magn Reson Chem 2010; 48: 392–396 [2] (compound 1) (Fig. [2]). Therefore the compound isolated by Ma et al. is to be renamed “Momordicoside X”.
