Chemical Composition of the Oil of Afrocarpus mannii, an Endemic Species from S.Tomé e Príncipe

The essential oils of leaves and bark of Afrocarpus mannii, an endemic species from S. Tomé e Príncipe, were investigated for the first time. The oils were obtained by hydrodistillation of the leaves and bark, and subsequently analyzed by GC, GC-MS and 13 C-NMR. The compositions of the two oils were...

Description
Summary:The essential oils of leaves and bark of Afrocarpus mannii, an endemic species from S. Tomé e Príncipe, were investigated for the first time. The oils were obtained by hydrodistillation of the leaves and bark, and subsequently analyzed by GC, GC-MS and 13 C-NMR. The compositions of the two oils were similar. They were characterized by the presence of limonene (31.3% and 39.1%), β-caryophyllene (13.1% and 12.4%) and germacrene D (12.6% and 11.0%) in the leaf and bark oils, respectively.
