Comparison on In vitro Bacteriostasis of the Different Extract from Dandelion

Through water extractive,water extractive 75%alcoholprecipitate and water extractive 85%alcoholprecipitate to prepare extractive of dandelion herbs and root. Dandelion compared to E.coli and Staphylococcus aureus in different parts of the antibacterial effect,to determine the best location and extraction of effective methods of inhibition.By sensitive paper disk method to determine the inhibitor effect of dandelion herbs and root on E.coli and Staphylococcus aureus.Dandelion herbs and root have conspicuous inhibitory action on the two kinds of bacteria,there is more sensitive to Staphylo-coccus aureus.Dandelion herbs is better than root,antibacterial effect of water extractive 75% alcohol precipitate is superior to water extractive and water extractive 80% alcohol precipitate.
