| Abstract: | The chemical composition and antimicrobial potential of Cistus munbyi essential oil were studied for the first time. GC and GC–MS analysis revealed 48 compounds representing 96.98% of the oil. Terpinen-4-ol (23.75%), meta-Cymene (17.30%), and Sabinene (12.38%) were the major constituents. Antimicrobial activity was evaluated against nine pathogens using the disc diffusion and broth micro-dilution methods. Results show that C. munbyi essential oil possesses strong antimicrobial activity against all strains, regardless if Gram-positive or Gram-negative bacteria, or yeast, with MICs values not exceeding 10 (mg/ml). In addition to its efficacy, C. munbyi essential oil has an unusual antimicrobial potency which is attributed to its specific chemical composition. Thus, findings presented here suggest that endemic C. munbyi contains a very interesting essential oil that may be valuable in several areas. |
