Kukurbitan je hemijsko jedinjenje sa formulom C
30H
54 (CAS broj 65441-59-0). On je policiklični ugljovodonik, specifično triterpen. Ovo jedinjenje je izomer lanostana (specifično 19(10→9β)abeo-lanostana), od kojeg se razlikuje po formalnom pomeranju metil grupe (ugljenika broj 19) sa 10 na 9β poziciju koristeći standardnu steroidnu numeracionu šemu.^[1]^[2]

Kukurbitan je ime za dva stereoizomera, koje nose prefikse 5α- i 5β, i koja se razlikuju po pozicijama supstituenata hiralnog ugljenika.^[1]
