梅片树叶挥发油和天然右旋龙脑的抑菌性能研究

Study on antibacterial activity of essential oil and D-borneol from leaves of Cinnamomun burmannii B1

目的:研究梅片树叶挥发油、天然右旋龙脑的体外抗菌性能。方法:采用K-B纸片琼脂扩散法测定梅片树叶挥发油、天然右旋龙脑和合成龙脑对细菌、植物病原真菌和动物源真菌的抑菌圈大小,并采用琼脂稀释法测定其最小抑菌浓度(MIC值)。结果:梅片树叶挥发油、天然右旋龙脑和合成龙脑有不同程度的抑菌作用,天然右旋龙脑和合成龙脑抑菌作用相似,梅片树叶挥发油的抑菌效果比较明显。结论:梅片树叶挥发油和天然右旋龙脑均有一定的抑菌活性,具有广阔的开发利用前景。

To investigate the antibacterial function of essential oil and D-borneol from leaves of Cinnamomun burmannii B1 in vitro.The K-B disc agar diffusion method was used to mensurate the size of antibacterial zone of essential oil and D-borneol from leaves of Cinnamomun burmannii B1,as well as synthetic borneol.The agar dilution method was used to determine their minimum inhibitory concentrations（MIC）.Essential oil,D-borneol and synthetic borneol had different level of inhibitory effect.D-borneol and synthetic borneol had similar inhibitory effect,and the antibacterial effect of essential oil was more significant.Essential oil and D-borneol showed antibacterial effects on the experimental strains,which exhibited a promising prospect for developing medical products and perfume.
