桉叶油体外抗菌作用的初步实验研究

A preliminary study on the anti-bacteria effect of Oleum Eucalypti

本文对桉叶油溶液抗菌作用进行了实验研究，当金黄色葡萄球菌为10~8个／ml时，65％桉叶油溶液的最小抑菌浓度（MIC）为1．3mg／ml，桉叶油丹参溶液MIC为0．163mg／ml，其最小杀菌浓度（MBC）分别为2．63mg／ml和0．326mg／ml。桉叶油对革兰阳性菌有抑菌作用，而桉叶油丹参复合液对革兰阳性、阴性菌均有较强抑菌作用，结果表明桉叶油及其与丹参的复合液都具有抗菌作用。

The anti-bacteria effect of Oleum Eucalypti was preliminarily investigated. The results showed that the minimal inhibition concentractions (MIC) of oleum Eucalypti and the mixture of Oleum Eucalypti and Salvia miltiorrhiza for aureus were 1. 3mg/ml and o.163mg/ml, their minimal bactericidal concentrations (MBC) for the same bacterium were 2. 6mg/ml and o. 326mg/ml respectively. The result also showed that the Oleum Eucalypti inhibited the gram-positive bacterium only the mixture of Oleum Eucalypti and Salvia miltorrhiza inhibited the gram-positive and negative bacteria.
