Essential oils and their components are increasingly spreading as naturally occurring antimicrobial agents. In this work the chemical composition and the antimicrobial properties of Pinus patula essential oils, a wild Pinaceae, which grows in several regions of Rwanda, were characterized and assessed. The essential oil was obtained by steam distillation and the chemical composition was determined using GC/MS. The in vitro antimicrobial activity of the essential oil was studied against two Gram-negative bacteria (Streptococcus pyogenis, Pseudomonas solanacearum) and one Gram-positive bacteria (Staphylococcus aureus) and two fungi (Pycularia oryzae, Colletotrichum coffeanum) using a broth macrodilution method and by agar diffusion method. During the chemical composition analysis, seventy-four components making up 99.11% of the oil were detected while only fifty components making up 95.70% of the oil were characterized, β-phellandrene (18.98%), α-pinene (15.91%), bornyl acetate (7.89%), β-caryophyllene (7.41%), limonene (5.67%) being the major constituents. The results of the in vitro antimicrobial assay showed that essential oil extracted from the rwandese Pinus patula has a strong activity against all tested bacteria and fungi, exception done to Colletotrichum coffeanum fungi.
