Composition and Chemical Variability of Ivoirian Polyalthia oliveri Leaf Oil

The chemical composition of 45 essential oil samples isolated from the leaves of Polyalthia oliveri harvested in three Ivoirian forests was investigated by GC ‐ FID (retention indices measured on two columns of different polarities), and by 13 C‐ NMR , following a method developed in our laboratory. In total, 41 components were identified. The content of the main components varied drastically from sample to sample: ( E )‐ β ‐caryophyllene (1.2 –...
