The aerial parts of Allium eriophyllum Var. eriophyllum (Syn. A. longisepalum Bertol.) were collected at full flowering stage.The essential oil was isolated by hydro distillation and analyzed by a combination of capillary GC and GC-MS. The main components were carvacrol (71.54%), Methyl (methylthio) methyl disulfide (9.51%), (E)-caryophyllene (8.37%) and β-bisabolene (4.38%). The in vitro antimicrobial activity of the essential oil of A. eriophyllum were studied against Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli and Candida albicans. The results of the bioassays showed that the oil exhibited high antimicrobial activity against all the tested pathogens compared standard antibiotics.
