The leaf, stem bark and root bark oils of Isolona cooperi Hutchinson & Dalziel from the Ivory Coast have been analysed by GC (retention index), GC‐MS and 13 C‐NMR spectroscopy. Two types of essential oil were produced by the plant. The leaf and stem bark oils were monoterpene‐rich, containing principally ( Z )‐ β ‐ocimene and γ ‐terpinene and three lactones, 5‐[( E and Z )‐hexylidene]‐5H‐furan‐2‐ones and massoia lactone, were present in appreciable amounts. Conversely, the root bark oil was dominated by 5‐isopentenylindole and ( E )‐ β ‐caryophyllene. The strategy for the analysis of each oil was adapted according to the nature of the components.
