The study's goal was to examine the chemical components and antimicrobial activity of turmeric essential oils on skin pathogens, which is critical. By the GC-MS method, nineteen chemical components in turmeric essential oil have been identified, of which six are hydrocarbons (such as 39.42% monoterpenes and 3.58% sesquiterpenes), and the rest are oxygenated hydrocarbons (8.09% alcohols, 3.12% aldehydes, and 44.24% ketones). The turmeric essential oils exhibited inhibitive effects on all of the test organisms. They showed excellent in vitro antimicrobial activity against all the tested skin pathogens, including gram-positive bacteria and yeast strains, with zones of inhibition ranging from 10.13 to 21.64 mm in diameter. The turmeric essential oils were most active against antibiotic-susceptible Staphylococcus epidermidis (MIC = 0.15 μL/mL). The MICs for turmeric essential oils ranged from 0.06 μL/mL to 0.68 μL/mL for all test microorganisms. These research results are a valuable premise for the development of research and the application of turmeric essential oil in medicine. © 2024 The Authors.EnglishAntimicrobial activityChemical componentsInhibitSkin pathogenTurmeric essential oilArticle
