Study on Antimicrobial Effects of Puchiin Extracts

Ethanol extracts of puchiin were assayed for its antimicrobial properities. The result showed puchiin extracts had antibacterial activities. Futhur more, it was revealed that puchiin extracts had strong anti-microbial activity against bacterial tested under the condition pH 7. Minimum inhibitory concentration value of extracts to Staphylococcus aureus, Escherichia coli and Bacillus subtilis was 0.63, 1.25, 1.25 g/L respectively, which was stronger than molds and budding fungus was weaker than that that of potassium sorbate. Antimicrobial activity against of potassium sorbate.
