Abstract: The paper desls with the antimicrobial action of different extract of bamboo leaves of phyllostachys glauca Mcclure to several pathogenetic microbes. the results showed that there were obvious antimicrobial actions between the extract A of bamboo leaves by alcohol and acetate acid and the extract B of bamboo leaves by alcohol. The antimicrobial minimum dosage of extracts A and B was respedtively ad follows: Salmonella typhi;0. 125%, 10%; Shigella dusenterlea: 0. 125%, 10%; Yersinia enterocolitica: 0. 25%, 20%; Staphylococcus aureus: 0. 25%, 10%; Bacillus cereus: 0. 125%, 10%; Clostridium Perfringens: 0. 25%, 20%;Ciostridium botulinum: 5%, 40%, When the period of time is the same, the higher the concentration of the extract, the higher the antimicrobial effect. When concentration were the same, the longer the reaction period, the higher the antimicrobial effect of the extract.
