摘要
研究了淡竹叶提取物的抑菌性能。结果表明：提取物对所试细菌有较强的抑制作用，而对霉菌的抑制效果不明显；对金黄色葡萄球菌的最低抑菌浓度为6．2％，对溶血性链球菌、绿脓杆菌和大肠杆菌的最低抑菌浓度都是12．5％；耐热性好；抑菌pH范围在pH4—9之间：具有良好的防腐保鲜效果。
Antimicrobial character of the extract from Lophatherum gracile Brongn. was studied in this paper. The results showed that the extract could effectively inhibit the growth of bacterium, hut not obviously to fungi. The MIC （Minimum Inhibition Concentration） was as follows： 6.2% to Staphylococcus aureus, 12.5% to Streptococcus haemolyc, Pseudomonas aeruginosa and Escherichia coli. The extract also had very good temperature stability and it could he effective from pH 4 -9. Antimicrohial effect on several common food of extract was obvious.
