Abstract:

Abstract: [Objective]The PAE of E. arvense and the PWE of E. arvense have different inhibitory effects on different bacterias. The drugs should be used in a rational way to ensure the best treatment effect. [Methods] The filter paper method was used to compare the bacteriostatic effect of the PAE of E. arvense and the PWE of E. arvense on Staphylococcus aureus and other two bacterias: The length of bacteriostatic belt indicated the bacteriostatic effect. [Results] In general, the PAE of E. arvense had stronger bacteriostatic effect than the PWE of E. arvense. Both the drugs had the strongest bacteriostatic effect on Staphylococcus aureus, weaker effect on Bacillus subtilis, and weakest effect on Escherichia coli. [Conclusion] The PAE of E. arvense contains elements such as flavonoid, alkaloid, and silicon compounds. Different chemical substances have different mechanisms in bacteriostasis, which may lead to the different bacteriostatic effect.
