水杉种子提取物抑菌机理研究

研究了水杉种子提取物的抑菌机理。方法:测定加入不同抑菌剂后的大肠杆菌液中还原糖含量、蛋白质含量以及电导率的变化。结果:水杉种子挥发油、总黄酮及提取物都具有一定的抑菌效果,抑菌效果随着浓度的增加显著提高,使大肠杆菌菌液的还原糖含量升高、蛋白质含量升高、电导率明显提高,其中以提取物的作用效果相对显著。结论:水杉种子提取物抑菌效果优于水杉种子挥发油、总黄酮,在天然产物抑菌剂开发方面前景广阔。

Study on the antibacterial mechanisms of the seed extracts of Metasequoia glyptostroboides

Object:To study the antibacterial mechanisms of the seed extracts of Metasequoia glyptostroboides.Methods:Test the changes of the reducing sugar content,the protein content,electric conductivity in the colon bacillus solution after being added different bacteriostatic agents.Result: All the essential oil,total flavones and compound extracts of the Metasequoia glyptostroboides seed have antibacterial effects,and the effects are better as the bacteriostatic agents’ consistency increased;and these three kinds of bacteriostatic agents can increase the reducing sugar content,the protein content,electric conductivity in the colon bacillus solution,especially the compound extracts of the Metasequoia glyptostroboides seed.Conclusion:The compound extracts of the Metasequoia glyptostroboides seed have better antibacterial effects than the essential oil,total flavones of it,and have good development prospects in the bacteriostatic action from natural products.
