Abstract:
Object To explore the regularity of recipe composition by observing different bacteriostasis among compositions of Gegen Qinlian Decoction (GQD) against Streptococcus pneumoniae. MethodsTo evaluate the minimal inhibitory concentration (MIC) of 15 decoctions through double fold dilution method. Results Not all of the decoctions are of the same MIC. Conclusion Not all of the 15 decoctions have the same bacteriostasis against S. pneumoniae. Among the four herbs of GQD Coptis chinensis Franch. has the strongest bacteriostasis and the next Scutellaria baicalensis Georgi. While Glycyrrhina wralensis Fisch and Pueraria lobata (Willd.) Ohwi have no bacteriostasis, but they can influence the bacteriostasis of C. chinensis and S. baicalensis when combinating with them.
