Application of natural medicine in preparation of antibacterial medicine

The invention relates to the technical field of medicines, in particular to application of a natural medicine in preparation of antibacterial medicines. According to the invention, various natural medicines can be used for preparing antibacterial medicines; mangiferin has a good inhibition effect on the growth of acinetobacter baumannii; the methyl caffeate has a good inhibition effect on acinetobacter baumannii; the invention also finds that harmine can be used as a synergist of meropenem to enhance the antibacterial effect of meropenem on klebsiella pneumoniae; single use of harmine or meropenem cannot inhibit the growth of klebsiella pneumonia, but when 128 [mu] g/mL harmine and 4 [mu] g/mL meropenem are combined for use, the growth of klebsiella pneumonia can be significantly inhibited, and the growth rate can be reduced to 5% or below. 本发明涉及医药技术领域，具体涉及一种天然药物在制备抗菌药物中的应用。本发明发现多种天然药物能够用于抗菌药物的制备；芒果苷对鲍曼不动杆菌的生长有很好的抑制作用；咖啡酸甲酯对鲍曼不动杆菌有很好的抑制作用；本发明还发现，去氢骆驼蓬碱能作为美罗培南的增效剂增强其对肺炎克雷伯杆菌的抗菌作用；去氢骆驼蓬碱单用或者美罗培南单用均不能抑制肺炎克雷伯杆菌的生
