Inhibition Of YinQiao Compound And Honeysuckle Extraction For Escherichia Coli, In Vitro

The Escherichia coli(E.coli) disease for Poultry has been one of the frequently factors for many years, and a great quantities of antibacterial drugs, leading more and more high resistance, is used to prevent accidents from the disease in control and cure. Through progressive research, inhibitory of the new YinQiao compound effect on E.coli078 compare with the old compound; Effect of antibacterial inhibitory have been tested for E. coli 078 based on a single herb Chinese medicine of YinQiao compound; and three kind of effective ingredients of honeysuckle were extracted to be research the performance of antibacterial inhibitory for E. coli 078, in vitro. The results are as follows:The results show that the antibacterial effect of the new formula YinQiao compound, in vitro is better than the old compound: In the antibacterial test of a single herb Chinese medicine of YinQiao compound, honeysuckle are the strongest compared with the other traditional Chinese medicine, antibacterial diameter is 16.3±0.11 mm:The effective ingredients of honeysuckle were extracted by supercritical C02, and the contents had been identified, including volatile oil, chlorogenic acid and flavonoid. The quantity of contents was 2.2%.4.52% and 3.13%. respectively. Of the three extraction ingredients was implemented to detect the activity of antibacterial inhibitory,in vitro. The results indicate that chlorogenic acid is the best kind of active composition among the three ingredients extracting from honeysuckle for antibacterial inhibitory. The antibacterial diameter is 10.2±0.04 mm. In these conclusions, the results will provided some information to further development and utilization of honeysuckle, and the research and development of a new drug of veterinary medicine.
