ResumoA new cytotoxic triterpene, 11-deoxocucurbitacin I was isolated from Desfontainia spinosa. The structure of this compound was elucidated by extensive analysis of the high field 1H NMR and 13C NMR spectra and field desorption mass spectrometry. This is the first example of a cucurbitacin lacking an 11-keto functionality.
