Aromatic Plants of Tropical Central Africa. XXXIV. Chemical Composition of Bark Essential Oils of Entandophragma cylindricum Sprague Growing in Cameroon and in Central African Republic

Abstract

The bark oils obtained by hydrodistillation from Entandophragma cylindricum Sprague growing in Cameroon and in Central Africa Republic were analyzed by GC and GC/MS. The major constituents of both oils were δ-cadinene (9.1–22.9%), α-copaene (6.5–21.9%) and T-cadinol (17.5–27.6%); however, the Cameroonian oil was found to be completely devoid of monoterpenoid compounds, whereas the Central African sample contained about 15% monoterpenoids.
