生姜挥发油的抑菌活性测定

Determination of Antibacterial Activity of Ginger Volatile Oil

以生姜为研究对象,应用直接蒸馏法提取全姜挥发油、去皮姜挥发油和姜皮挥发油,比较3种挥发油对6种常见细菌的抑菌活性,研究生姜挥发油的抑菌效果。结果显示,3种挥发油对常见细菌均有不同程度的抑制作用,对革兰氏阳性菌的抑制效果更佳;3种挥发油的抑菌效果依次为去皮生姜油>全姜挥发油>姜皮挥发油。

Ginger was used as the research object,and the whole ginger volatile oil,peeled ginger volatile oil and ginger peel volatile oil were extracted by direct distillation,and the antibacterial effect of ginger volatile oil was investigated by comparing the antibacterial activity of the three kinds of volatile oils against six kinds of common bacteria.The results showed that the three kinds of volatile oils had different degrees of inhibitory effect on common bacteria,and the inhibitory effect on Gram-positive bacteria was better;the inhibitory effect of the three kinds of volatile oils was in the order of peeled ginger oil>whole ginger volatile oil>ginger skin volatile oil.
