The antimicrobial activity of juniper berry essential oil (Juniperus communis L., Cupressaceae)

Juniper essential oil (Juniperi aetheroleum) was obtained from the juniper berry, and the GC/MS analysis showed that the main compounds in the oil were - pinene (29.17%) and -pinene (17.84%), sabinene (13.55%), limonene (5.52%), and mircene (0.33%). The juniper essential oil has been evaluated for the antimicrobial activity against sixteen bacterial species, seven yeast-like fungi, three yeast and four dermatophyte strains. Juniper essential oil showed similar bactericidal activities among Gram-positive and Gram-negative bacterial species ; with MIC values between 8 and 70% V/V. Juniper essential oil possess strong fungicidal activity against yeasts, yeast-like fungi and dermatophytes with the MIC values below 10% V/V. The strongest fungicidal activity has been noticed against Candida spp. (MIC from 0.78 to 2 %V/V) and dermatophytes (from 0.39 to 2 % V/V).
