ABSTRACT

OBJECTIVE To evaluate the pharmacological actions of the Formulae of Qinwenbaiduyin and Huanglianjiedutang in antibacterial experiment in vitro. METHODS Test tube method and plating method were employed in antibacterial experiment while test was conducted in antiviral experiment with extract of the Formula by water and then observing the pathological changes in the lungs after medication. RESULTS The minimal inhibirory concentration (MIC) effect of Qinwenbaiduyin was 15.6 mg/ml, the minimal bacteriocidal concentration (MBC) was 31.2mg/ml to Staphylococcus aureus; minimal inhibirory concentration (MIC) effect was 7.6mg/ml, MBC was 15.6mg/ml to Escherichia coli. The MIC effect of Qinwenbaiduyin was 15.6 mg/ml, the MBC was 31.2mg/ml to S. aureus and E. coli. CONCLUSIONS The Formulae of Qinwenbaiduyin and Huanglianjiedutang have antibacterial effect on S. aureus and E. coli in experiment.
