- Abstract
[Objective] The paper was lo explore the combined inhibitory effect of rhizoma coptidis-folium isatidis and rhizoma coptidis-flos poprli against Escherichia coli O2. [Method] Contrast test of single and associated bacteriostasis against known serotype E. coli O2 was conducted using microcheckerboard method. [Result] The MIC of rhizoma coptidis, folium isatidis and flos poprli were 1/8 extracting liquid, 1/8 extracting liquid and 1/2 extracting liquid, respectively. When combined with folium isatidis or flos poprli, the MIC of rhizoma coptidis was 1/8 extracting liquid or 1/16 extracting liquid compared with single use. When combined with rhizoma coptidis, the MIC of folium isatidis and flos poprli wTere 1/8 extracting liquid and 1/16 extracting liquid. [Conclusion] When rhizoma coptidis was combined with folium isatidis or flos poprli, the FIC values were 2 and 0.625, performing independent action and additive effect, respectively.
