| Abstract: | The inhibition effect of gnaphlium affine D.Don extract on normal pathogenic bacteria was tested, and the results showed that the extract presented certain inhibitory effects on normal pathogenic bacteria, and the antimicrobial effect were staphylococcus aureus>salmonella>Bacillus subtilis>Escherichia coli. The smallest bacteriostasis density was as follows: staphylococcus aureus1.25%,salmonella2.5%,Escherichia coli10%,Bacillus subtilis 10%. |
