射干和马齿苋对46株绿脓杆菌体外抑菌试验的研究

Experimental research on antibacterial effect of Belamcanda Chinensis DC and portulaca oleracece L on P. aeruginosa in vitro

目的 :探讨射干、马齿苋对绿脓杆菌 ( PA)的体外抑菌作用。方法 :取射干、马齿苋水煎剂对4 6株PA进行 MIC试验 ,统计 MIC50 和 MIC90 。结果 :射干水煎剂对 PA MIC范围为 31.2 5～ 3.90 g/ L,MIC50 为 7.81g/ L,MIC90 为 15.62 g/ L;马齿苋水煎剂对 PA MIC范围为 31.2 5～ 7.81g/ L,MIC50 为15.62 g/ L,MIC90 为 31.2 5g/ L。结论 :射干、马齿苋于体外对绿脓杆菌有较强抑制作用。

Objective:To explore the antibacterial effect of Belamcanda Chinensis DC and Portulaca oleracece L on P.aeruginosa (PA) in vitro.Methods:Fourty six strains PA were tested for minimum inhibition concentration (MIC) by water decoct agents of the two drugs.MIC 50 and MIC 90 were statistically studied.Results:For Belamcanda Chinensis DC,MIC was 31.25~3.90 g/L;MIC 50 was 7.81 g/L,and MIC 90 was 15.62 g/L;whereas, for portulaca oleracece L,MIC was 31.25~7.81 g/L, MIC 50 was 15.62 g/L,and MIC 90 was 31.25 g/L. Conclusion :Both of the two drugs have stronger antibacterial effects on P.aeruginsosa in vitro. [
