Key Word Index-Olea madagascariensis; Oleaceae; dammarenediol; dammaradienol; sterols; fatty acids.Abstract-The neutral lipids of the fruits (pulp and kernel) of Olea madagascariensis contain about 10percent of unsaponifiable matter.Twenty-six 4-demethylsterols and 4,4-dimethylsterols were identified.Among them two compounds, (20S)-5α-dammar-24-en-3β,20-diol and 5α-dammara-20(21),24-dien-3β-ol, represent 3.3 and 3.2percent of the neutral lipids, respectively.The assigned structures of the two main components are based upon GC retention times, 1H and 13C NMR, and mass spectrometry.
