Siraitic acid F, a new nor-cucurbitacin with novel skeleton, from the roots of Siraitia grosvenorii.
A new cucurbitane triterpene, siraitic acid F (1), has been isolated from the roots of Siraitia grosvenorii (Swingle) C. Jeffrey, and its structure has been elucidated as 29-nor-4,24-diene-3,11-dioxo-19-hydroxy-6,19-cyclocucurbitane-26-oic acid on the basis of spectroscopic evidences, including a series of 2D NMR analyses.
