    Abstract:

    In this study， Artemisia argyi essential oils were extracted by simultaneous distillation（SDE）with dichloromethane and n-hexane，respectively. To explore the differences of antimicrobial activities，components of the oil were analyzed by GC-MS，and scanning electron microscope（SEM）was used to explore the mechanism of antimicrobial activity. Compared with the steam distillation，SDE saved one hour and had a three times higher yield（1.5%). SDE（n-hexane）oil had a higher antimicrobial activity with the minimum inhibitory concentration（MIC） being 6.25 μL/mL. GC-MS results revealed that the SDE（n-hexane）oil had 92.95% similarity in the chemical composition with the oils extracted with steam distillation and SDE（dichloromethane). SEM results showed that the antibacterial activity of Artemisia argyi essential oil could be achieved by disruption of cell wall.
