茶树油妇女洗液抗菌性能研究

STUDY ON ANTIMICROBIC PROPERTY OF TEA TREE OIL WOMAN LOTION

为观察茶树油妇女洗液的抗菌作用,采用悬液定量试验方法对其最低抑菌浓度和杀菌效果进行了测定。结果,用茶树油妇女洗液原液对金黄色葡萄球菌和大肠杆菌作用5m in,杀灭率分别为100%和99.97%;对白色念珠菌作用10m in,杀灭率为99.20%。该洗液对白色念珠菌、金黄色葡萄球菌和大肠杆菌的最低抑制浓度分别为体积分数2%、10%和12.5%。菌悬液内含25%以上的小牛血清,对茶树油妇女洗液杀灭白色念珠菌的效果有轻度影响,随有机物含量增加影响更为明显。结论,茶树油妇女洗液对细菌繁殖体和真菌均具有明显的杀菌和抑菌作用,但其受有机物影响明显。

In order to observe the antimicrobic effect of tea tree oil woman lotion, suspension quantitative test method was used to determine its minimal microbe - inhibiting concentration and germicidal efficacy. Results： The killing rates of Staphylococcus aureus and Escherichia coli exposed to the stock solution of the tea tree oil woman lotion for 5 min were 100% and 99.97% respectively and that of Candida albicans exposed for 10 min was 99.20%. The minimal inhibition concentrations of the lotion for Candida albicans , Staphylococcus aureus and Escherichia coli were 2%, 10% and 12.5% （v/v） respectively. Over 25% of calf serum in the fungal suspension slightly influenced the efficacy of the tea tree oil woman lotion in killing Candida albicans and the influence increased with increasing the organic substance content. Conclu- sions ： The tea tree oil woman lotion has significant germicidal and inhibiting effects on both vegetative forms of bacteria and fungi, but its effects were influenced siginificantly by organic substance.
