Popis:	L’huile essentielle de la partie aerienne de Porophyllum ruderale (Jacq.) Cass. (Asterales ; Asteraceae) obtenue par entrainement a la vapeur a ete analysee par Chromatographie en Phase Gazeuse couplee a la Spectrometrie de Masse. L’activite antimicrobienne de l’huile essentielle a ete evaluee sur des bacteries et champignons de reference du Centre Suisse de Recherches Scientifiques en Cote d’Ivoire. L’huile essentielle est constituee essentiellement de monoterpenes (94,69%), d’hydrocarbures aromatiques (4,39%) et de sesquiterpenes (0,27%). Les composes majoritaires sont βmyrcene ( 35,52%), γ-terpinene (26,37%), β-pinene (21,65%), limonene (9,26%) et 1-undecene (4,39%). L’huile essentielle a inhibe la plupart des souches testees, Klebsiella pneumoneae, Bacillus subtilus CIP, Staphylococcus aureus, Staphylococcus epidermidis, Candida albicans, Candida tropicalis et Candida glabrata, avec une concentration minimale inhibitrice (CMI) de 3,75mg/ml. Cependant , elles ne possedent aucun effet sur Salmonella typhimirium SO 66, Escherichia coli ATCC 25922 et Pseudomonas aeruginosa ATCC 27853. Cette etude a revele la composition chimique de l’huile essentielle de la partie aerienne de P. ruderale. Elle a en outre montre le bon potentiel antimicrobien de l’huile essentielle. Essential oil of the aerial part of Porophyllum ruderale (Jacq.) Cass. (Asterales; Asteraceae) obtained by steam distillation was analyzed by Gas Chromatograhy coupled to Mass Spectroscopy. Then the antimicrobial activity of essential oil was evaluated on reference bacteria and fungi from the Swiss Center for Scientific Research in Cote d'Ivoire. Essential oil consists mainly of monoterpenes (94.69%), aromatic hydrocarbons (4.39%) and sesquiterpenes (0.27%). The major compounds are β-myrcene (35.52%), γterpinene (26.37%), β-pinene (21.65%), limonene (9.26%) and 1-undecene (4.39%). Essential oil inhibited most of the strains tested, Klebsiella pneumoneae, Bacillus subtilus CIP, Staphylococcus aureus, Staphylococcus epidermidis, Candida albicans, Candida tropicalis and Candida glabrata, with a minimum inhibitory concentration (MIC) of 3.75 mg/ml. However, they have no effect on Salmonella typhimirium SO 66, Escherichia coli ATCC 25922 and Pseudomonas aeruginosa ATCC 27853. This study revealed the chemical composition of the essential oil of Porophyllum ruderale. It also showed the good antimicrobial potential of this essential oil.
