| Abstract: | Objective] Study on antibacterial activity and stability of the ethanol extracts from Allium mongolicum Regel.Method] Taking Allium mongolicum Regel.(AMR)as experimental material,the antibacterial and stability test,antibacterial capacity and antibacterial activity substance stability of extracts were studied.Result] Size order of antibacterial effect of extracts on these 5 strains tended to be:Saccharomyces cerevisiae > Penicillium sp.> Aspergillusniger> Staphylococcusaureus> Escherichia coli;under neutral or slight alkaline conditions,optimum antibacterial effect presented best;and UV light irradiation basically had no influence on tested strains.Conclusion] Antibacterial effect of ethanol extract shows great difference among these strains,and antibacterial activity substance is of good heat and UV light stability. |
