以吴茱萸挥发油为研究对象,进行空气抑菌、平板抑菌、液体培养等试验,并通过气相色谱-质谱(GC-MS)联用技术对吴茱萸挥发油进行化学成分分析。结果表明:吴茱萸挥发油对空气中的细菌和真菌的抑菌率分别为97.86%和99.50%;对大肠杆菌、金黄色葡萄球菌和枯草芽孢杆菌均有抑制效果,但对革兰氏阴性菌的抑制效果较弱,而对革兰氏阳性菌的抑制效果较强;经4.5%的挥发油作用24 h后,金黄色葡萄球菌细胞与细胞间界限模糊,菌体结成团块,并且有不规则凸起或凹陷,结构破坏严重,菌内物质外漏,最后裂解成碎片。GC-MS检测的色谱峰超过100个,经鉴定吴茱萸挥发油主要成分为月桂烯、β-蒎烯、柠檬烯及罗勒烯,占总成分的78.66%。
以吳茱萸揮髮油為研究對象,進行空氣抑菌、平闆抑菌、液體培養等試驗,併通過氣相色譜-質譜(GC-MS)聯用技術對吳茱萸揮髮油進行化學成分分析。結果錶明:吳茱萸揮髮油對空氣中的細菌和真菌的抑菌率分彆為97.86%和99.50%;對大腸桿菌、金黃色葡萄毬菌和枯草芽孢桿菌均有抑製效果,但對革蘭氏陰性菌的抑製效果較弱,而對革蘭氏暘性菌的抑製效果較彊;經4.5%的揮髮油作用24 h後,金黃色葡萄毬菌細胞與細胞間界限模糊,菌體結成糰塊,併且有不規則凸起或凹陷,結構破壞嚴重,菌內物質外漏,最後裂解成碎片。GC-MS檢測的色譜峰超過100箇,經鑒定吳茱萸揮髮油主要成分為月桂烯、β-蒎烯、檸檬烯及囉勒烯,佔總成分的78.66%。

The experiments of air bacteriostasis, plate bacteriostasis and liquid culture were conducted to the volatile oil of Evodia rutaecarpa, and then the chemical components of the volatile oil of Evodia rutaecarpa were analyzed by GC-MS. The results showed that the bacteriostatic rate of the volatile oil of Evodia rutaecarpa to bacteria and fungi in the air reached 97.86% and 99.50%, respectively;while it also showed a bacteriostatic effect to Escherichia coli, Staphylococcus aureus and Bacillus subtilis, a strong bacteriostatic effect to Gram-negative bacteria, but a weak bacteriostatic effect to Gram-negative bacteria; treated with 4.5% volatile oil for 24 h, the boundary between cells of Staphylococcus aureus was indistinct, the thalli formed a block mass with irregular heave or depression, and the structure damaged badly and substance in bacterial leaked out, and then split into pieces. Over 100 chromatographic peaks were detected by GC-MS, and the main chemical components of Evodia rutaecarpa volatile oil were identified as myrcene, β-pinene, limonene and ocimene, which accounts for 78.66% of total components.
