Air-dried leaves from Burkina Faso yielded 1.2% oil, with as main compounds β-pinene (31.0%), α-pinene (20.1%), limonene (16.8%), β-caryophyllene (6.6%), γ-terpinene (5.6%), p-cymene (3.2%), α-terpineol (3.1%) and bicyclogermacrene (2.0%). Fresh leaves from Nigeria yielded 0.28% essential oil. The major compounds were α-thujene (32.9%), 1,8-cineole (13.3%), p-cymene (12.9%), β -caryophyllene (7.8%), α-terpineol (2.6%), spathulenol (2.2%) and caryophyllenoxide (1.9%). The oil showed activity against the bacteria ''Escherichia coli'' and ''Pseudomonas aeruginosa'', but not against the bacteria ''Bacillus cereus'' and ''Staphylococcus aureus'' and the fungus ''Candida albicans''. Fresh leaves from DR Congo yielded 0.22% essential oil, with as main compounds β-pinene (25.3%), β-terpineol (13.6%), p-cymene (7.4%), α-terpineol (6.2%), 1,8-cineole (5.2%), limonene (4.6%), β-eudesmol (4.6%), α-pinene (4.3%), β-caryophyllene (4.3%) and spathulenol (4.1%). This oil showed activity against a range of bacteria and fungi.
