Cucurbitane is a class of
tetracyclic
chemical compounds with formula C
30H
54 (
CAS number 65441-59-0). It is a
polycyclic
hydrocarbon, specifically
triterpene. It is also 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.

[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]
Compounds with the basic cucurbitane skeleton are found in many plants, and some are important phytopharmaceuticals. [3] Natural cucurbitane-related compounds include:
