Study on antibacterial effect of medlar and hawthorn compound Extract in vitro
Abstract
This paper is to study the antibacterial effect of medlar and hawthorn compound extract in vitro. Water extract method and ethanol extraction method are adopted to prepare the compound extracts, and disc diffusion
method and improved test tube doubling dilution method are adopted to make the antibacterial test to the two common pathogenic bacteria in vitro, Staphylococcus aureus and Klebsiella pneumoniae. The results show that
medlar and hawthorn compound extract is moderately sensitive to Staphylococcus aureus, while its inhibiting effect on Klebsiella pneumoniae is particularly significant, and the antibacterial effect of ethanol extract is better
than water extract. Conclusion is that the medlar and hawthorn compound has good antibacterial effect on the two pathogenic bacteria.
