摘　　要：采用K—B纸片法考察了茶树油和壳聚糖对肺炎链球菌、肺炎克雷伯菌、金黄色葡萄球菌及大肠埃希菌的抑菌性；测定了茶树油和壳聚糖对实验菌的最小抑菌浓度（MIC）；最后，用定量法测定了茶树油和壳聚糖复合体系的杀菌率。结果表明，5～100mL／I。茶树油对实验菌有很强的抑菌性；壳聚糖在1～4g／L范围内对实验菌有一定抑菌性，但不明显；茶树油和壳聚糖对4种实验菌均有抑菌作用的最小浓度分别为5mL／L和1g／L；5mL／L茶树油和1g／L壳聚糖形成的茶树油和壳聚糖复合体系对实验菌具有快速且良好的杀茵效果。The antimicrobial activity of tea tree oil and chitosan against Streptococcus pneumonia （S. pneumo nia ）, Klebsiella pneumonia （K. pneumonia）, Staphylococcus aureus （St. aureus） and Escherichia coli （E. coli） were examined by K-B method. The minimum inhibitory concentrations （MIC） of tea tree oil and ehitosan against the four tested bacteria were measured, respectively. Finally, the sterilization rates of tea tree oil and chitosan composite liquid was determined by quantitative method. The results showed that chitosan in range of 1--4 g/L did had antibacterial properties, but not obviously, while 5--100 mL/L of tea tree oil had strong antimicrobial properties on tested bacteria. The minimum concentration of tea tree oil and chitosan that had inhibitory effects against four experimental bacteria was 5 mL/L and 1 g/L, respectively. The 1 g/L ehitosan and 5 mL/L tea tree oil composite system exhibited great and fast bactericidal effect on experimental bacteria.
