Cucurbitacin B is a cucurbitacin in which a lanostane skeleton is multi-substituted with hydroxy, methyl and oxo substituents, with unsaturation at positions 5 and 23; a hydroxy function at C-25 is acetylated. It is a tertiary alpha-hydroxy ketone, a cucurbitacin and a secondary alpha-hydroxy ketone. It derives from a hydride of a lanostane.
