Abstract

TERPENES AND FATTY ACIDS FROM Dipteryx lacunifera Ducke. This paper describes the isolation of the furanocassane-type diterpene, named vinhaticoic acid, along with β-farnesene and spatulenol from fruit shells of D. lacunifera. Structural determinations were accomplished by chemical derivatization and spectral analysis, including 1D and 2D NMR and X–ray crystallography. The fatty portion was extracted from the fruit kernels, transesterfied and analysed by HRGC/MS. Oleic acid (75.8 ± 4.3%) was the major component. Essential oil extracted from the fruit shells of D. lacunifera was analysed by HRGC/MS and nine sesquiterpenes were identified; β-farnesene (48.6%) and spatulenol (21.61%) were the major constituents.
