| Abstract: | Antimicrobial character of the extract from Lophatherum gracile Brongn.was studied.The results showed that the extract could effectively inhibit the growth of bacterium,but 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 be effective from pH 4~9.Antimicrobial effect on several common food of extract was obvious. |
