    abstract = {Essential Oils from dry fruits of <I>Xylopia aethiopica</I> and <I>Syzgium aromaticum</I> were obtained by steam distillation, using a Clevenger-type system. The composition was determined by means of gas chromatography-mass spectrometry techniques using direct injection. The oils were also screened for antibacteria activity against <I>E. coli</I>, <I>Serratia</I> sp,<I> Salmonella typhi</I>,<I> Klebsiella</I> sp,<I> citrobacter</I> and <I>Pseudomonas aeruginosa</I>. The oil yields were 1.2 and 7.4% for <I>Xylopia aethiopica</I> and <I>Syzgium aromaticum</I>, respectively.  The  results  showed  that  twenty  three  and three constituents representing 74 and 99.9% of the  o ils were conclusively identified from <I>X. aethiopica</I> and <I>S. aromaticum</I>, respectively. &szlig;-pinene 13.78%, &szlig;-phelladrene, 12.36% gama-terpinene 7.66% and  -pinene 5.56% as the major components of <I>X. aethiopica</I> and <I>eugenol</I> 93.7% for <I>S. aromaticum</I>. The two oils show demonstrated  activity  against  tested  organisms  with <I>S. aromaticum</I> having  higher activity than <I>X. aethiopica</I> at different concentrations.}
