Abstract

Objective To observe antibacterial activity of the Wikstroemia indica decoction against four kinds of bacteria.Methods The bacteriostasis was determined by agar diffusion method in vitro.The minimum inhibitory and minimum bactericidal concentrations(MIC and MBC respectively) were tested using the doubling dilution method.Results Wikstroemia lndica decoction showed antibacterial activity against 4 tested bacteria.The MIC of Bacillus coli,Staphylococcus aureus,Bacillus subtilis,Sarcina lutea were 156mg/ml,78mg/ml,78mg/ml and 39mg/ml,respectively;furthermore the MBC of the four kinds of bacteria were 312mg/ml,156mg/ml,156mg/ml and 78mg/ml,respectively.Conclusion The antibacterial activity was displayed as follow from strong to weak:Sarcina lutea,Staphylococcus aureus,Bacillus subtilis and Bacillus coli.And the antibacterial activity depended on the concentration of the decoction.
