Cucurbitane is a chemical compound with formula C
30H
54 (CAS number 65441-59-0). It is a polycyclic hydrocarbon, specifically a triterpene. It is an isomer of lanostane (specifically 19(10→9β)-abeolanostane), from which it differs by the formal shift of a methyl group (carbon number 19) from the 10 to the 9β position in the standard steroid numbering scheme.[1][2]


The name is applied to two stereoisomers, distinguished by the prefixes 5α- and 5β-, which differ by the handedness of the bonds at a particular carbon atom (number 5 in the standard steroid numbering scheme).[1]
