Abstract： In this paper， through a series of parameters such as extraction temperature， extraction time， ethanol concentration and compound proportion， the single factor antibacterial test with different compound proportion were carried out. It was determined that the ethanol extract of dried moss and bamboo shoots had a good inhibitory effect on Staphylococcus aureus， Escherichia coli， Bacillus subtilis and Bacillus cereus. When the single variable is the compound ratio， the higher the proportion of dry moss， the better the antibacterial effect.
