摘  要：
[目的]研究紫草[Arnebia euchroma(Royle) Johnst]与大青叶(Isatis indigotica Fort)提取物对6株腐败微生物和致病菌的抑菌性能及其最小抑菌浓度(MIC)。[方法]采用滤纸片扩散法。[结果]紫草提取物对猪粪链球菌、炭疽杆菌、李斯特氏菌、金黄色葡萄球菌均有较强的抑制效应,MIC分别为0.03、0.03、0.08、0.11mg/ml,而对沙门氏菌和大肠杆菌的抑制效果相对较弱。大青叶提取物对金黄色葡萄球菌、沙门氏菌、李斯特氏菌、炭疽杆菌均有较强的抑制效应,MIC分别为0.08、0.19、0.20、0.56mg/ml,而对猪粪链球菌和大肠杆菌的抑制效果较差,MIC分别为1.08、1.16mg/ml。[结论]为开发和应用大青叶与紫草提取物作为功能性天然防腐剂提供参考。

摘  要：
[Objective] The research aimed to study the effects of different concentrations Arnebia euchroma (Royle) Johnst and Isatis indigotica Fort extracts on the bacteriostasis and minimal inhibitory concentrations(MIC)of 6 strains food-borne microorganism and pathogenic bacteria(Escherichia coli,Salmonella typhimurium,Staphyloccocus aureus,Listeria monocytogenes,Streptococcus faecalis,Bacillus anthra). [Method] The filter paper dispersion method was used. [Result] The results showed that Arnebia euchroma (Royle) Johnst extracts had a strong inhibition on S. faecalis,L. monocytogenes,B. anthracis and S. aureus,and their minimal inhibitory concentrations(MIC) were 0.03,0.03,0.08 and 0.11 mg/ml,respectively. While Arnebia euchroma (Royle) Johnst extracts had a weak inhibition on S. typhimurium and E. coli. Isatis indigotica Fort extracts had a strong inhibition on S. aureus,L. monocytogenes,S. typhimurium and B. anthracis,and their MIC were 0.08,0.20,0.19 and 0.56 mg/ml,respectively. While Isatis indigotica Fort extracts had a weak inhibition on the S. faecalis and E. coli with MIC of 1.08 and 1.16 mg/ml,respectively. [Conclusion] The study can peovide reference for developing and applying Arnebia euchroma (Royle) Johnst and Isatis indigotica Fort extracts as functional nature preservative.
