Essential Oils and Non-volatile Compounds Derived from Chamaecyparis obtusa: Broad Spectrum Antimicrobial Activity against Infectious Bacteria and MDR(multidrug resistant) Strains

摘要

The aim of this study was to evaluate the antibacterial activity of essential oil from Chamaecyparis obtusa against general infectious microbes and drug resistant strains of clinical origin. The results indicate that both essential oil and non-volatile residue have broad inhibitory activity against test strains. Essential oil and non-volatile residues showed antimicrobial activity not only against general infectious bacteria, but also against methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE) strains.
