The chemical composition of the essential oils of the leaves and seeds of Jatropha integerrima was investigated by GC and GC-MS. The results showed significant variation in the chemical constituents of the tissue/parts analyzed. The leaf has pentadecanal (32.4%), 1,8-cineole (11.2%) and β-ionone (10.8%) as the major components. On the other hand, the seed oil is comprised mainly of aliphatic hydrocarbons represented by pentacosane (13.6%), hexacosane (13.3%), octacosane (12.3%) and heptacosane (10.1%). However, the defatted seed oil was predominantly made up of the monoterpenes 1,8-cineole (35.5%), p-cymene (20.5%) and α-pinene (16.5%). The oils displayed weak antimicrobial activity against Bacillus cereus and Staphylococcus aureus.
