[en] Steam distillation of Xylopa aethiopica (Annonaceae) dried fruits collected at Badou in Akposso region (Togo) gave a colourless essential oil with an overall yield of 3.5% (dry matter). From GC and GC/MS analysis 43 components were identified which represented more than 95% of the essential oil composition. The major components are found to be β-pinene (31.92%), germacrene-D (13.04%), α-pinene (10.28%), sabinene (7.88%), 1,8-cineole (4.87%). Xylopa aethiopica essential oil had a strong and interesting insecticidal activity against Callosobruchus maculatus a major cowpea stored products pest. With dose of 7µL/L of essential oil, more than 98% mortality of weevil was observed after 24 hours of application.
