Camphor tree leaves, such as plant bacteriostat qualitative extraction and bacteriostatic effect research
Abstract: In recent years, Growing bacterial resistance spectrum, Control effect of antimicrobial drugs fall, And easy in vivo formation of residual poultry, affecting human health and public health security of bioactive substances of plant origin compared with chemical synthesis matter, has little toxicity to human and animal, not easy the creation bears the medicine, less side effects and low environmental pollution, and low residual, has caused extensive concern of the global scholars. Comprehensive above, based on our country has rich oil resources, and use only in crude extract oil, camphor, and many oil monomer in the camphor oil substances underused, therefore on the basis of preliminary laboratory studies, this study intends to main chemical compositions of the oil, camphor oil (1, 8 - eucalyptus oil, a - terpineol, pine oil, thin - 4 - alcohol, Y - pine oil refining) as the research object, research on the harm in veterinary clinic larger escherichia coli bacterium antibacterial activity, with good resistance to e. oli hoof pick activity of natural medicine, and study its antibacterial mechanism, laying the groundwork for hoof choose si standard drugs. This paper first introduces the camphor tree, then the camphor tree focuses on antibacterial material and antibacterial effect, Cinnamomum japonicum oil paint on bacterial inhibition is relatively strong. The camphor tree leaves essential oil has a strong inhibitory effect on fungi. in order to later of plant essential oil bacteriostatic research provides certain reference value.
