Five microorganisms sensitive to Alcillea biebersteinii Afan. were included Salmonella typhimurium ATCC 25241 (8-10 mm), Bacillus subtilis ATCC 6051 (8-10 mm), Pseudomonas aeruginosa ATCC 10145 (10-10 mm), Staphylococcus aureus ATCC 12600 (9-10 mm) and Escherichia coli ATCC 11775 (8-9 mm). Meanwhile, GC/MS analysis of oil releaved twenty-one compounds with the main compounds as camphor (20.77 %), 1,8-cineol (18.60 %), artemisia ketone (14.69 %), camphene (7.80 %), α-pinene (5.94 %), artemisia alcohol (5.88 %), β-phellandrene (4.87 %) and chrysanthenone (4.33 %), respectively.eninfo:eu-repo/semantics/openAccessAchillea Biebersteinii Afan.Artemisia KetoneEnterecoccus FaecalisArticle2712N/AQ446864688
