云南薄荷精油的化学成分及其抗菌活性研究

摘要

采用GC/MS法对云南薄荷精油挥发性成分进行鉴定,检测出49个成分,鉴定了其中44个成分.薄荷精油主要化学成分为薄荷醇、薄荷酮、苧烯、1,8-桉叶素、胡椒酮、大根香叶烯D、乙酸薄荷酯等.试验研究了薄荷精油对大肠杆菌、金黄葡萄球菌、烟曲霉菌、白念珠菌的抗菌活性.结果显示精油对大肠杆菌、金黄葡萄球菌、白念珠菌有明显的抗菌活性.%The chemical constituents of the Mentha arvensis oil of Yunnan were studied by GC/MS method in this paper. 49 Constituents were isolated, 44 constituents were identified. They are menthol, menthone, limonene, 1,8-cineole, piperitone, germacrene-D and menthyl acetate, etc. The study on the antimicrobial activity of the Mentha arvensis essential oil against Staphylococcus aureus, Escherichia coli, Aspergillus fumigatus and Candida albicans were also conducted. The results show that the oil has antimicrobial activity to Escherichia coli, Staphylococcus aureus and Candida albicans.
