[en] The objective of this work is to study the variability of the chemical composition of essential oils of fruits of Xylopia aethiopica from southern Senegal. Essential oils were obtained by steam distillation on the fresh (F), shade-dried (DSh) and sun-dried (DS) fruits of Xylopia aethiopica. Analyzes of these essential oils carried out by GC/FID and GC/MS revealed three major compounds: β-pinene, 1,8-cineole and α-pinene in variable proportions. β-Pinene was identified for 29.9% (F), 15.1 to 31.2% (DSh) and 27.0 to 30.7% (SS), 1,8-cineole represented 14.7% (F), 14.5 to 15.1% (DSh) and 17.4 to 21.2% (SS) and α-pinene constituted 10.0% (F) 3.7 to 11,0% (DSh) and 6.6 to 10.0% (DS).
