60种食药两用中药抗菌防腐作用研究

STUDIES ON ANTIMICROBIAL EFFECTS OF 60 TRADITIONAL CHINESES HEALTH FOODS

本实验利用无菌24-孔板采用连续稀释法对60味食药两用中药进行了抗19种常见食品腐败菌的快速筛选,得到有明显抗菌作用的中药5种:丁香、花椒、高良姜、甘草、乌梅。其中:丁香、花椒、高良姜为香料,有较强的抗真菌作用;乌梅对所测细菌有较强抑制作用,将丁香、花椒、高良姜等等量组成复方进行抗菌实验,得出该复方的醇提物抗菌作用强于水提物,在浓度为1/80时对所有被测菌均有抑制作用。

In order to find out antimicrobial traditional Chinese health food,24 well culture plate was used to determine antimicrobial effects on 19 strains of food-spoilage microorganisms. Of the 60 extracts of traditional Chinese health foods, 5 showed remarkable antimicrobial activity against the tested strains,3 of which (F. caryophylli ,P. zanthoxyli,R. alpiniae)exhibited a strong antifungal activity, and 1 of which (F. mume) exhibited an strong activity against the tested bacteria. The results also showed that the complex,composed of F. caryophylli,P. zanthoxyli,R. alpiniae and so on at the same ratios,had a more effective antimicrobial activity in alcohol extract than in water extract. The alcohol extract inhibited all microorganisms tested in this study at the concentration of 1/80.
