Kokzeylanol and kokzeylanonol obtained from Kokoona zeylanica have been shown to be 6β,27-dihydroxy-D:A-friedo-olean-3-one (1) and 6β,27-dihydroxy-D:A-friedo-oleana-3,21-dione (2), respectively by the deoxygenation of their 27-acetoxy derivatives using Lithium-ethylene diamine reduction coupled with spectroscopic and irradiation methods.Kokzeylanonol represents the first tetraoxygenated C:A-friedo-oleanoane isolated from a natural source.
