摘要: 采用水蒸气蒸馏法、同时蒸馏萃取(SDE)法和微波辅助水蒸气法提取牛至挥发精油,并用GC-MS分离鉴定,比较不同提取方法精油的得率及所得精油中具有抑菌功能的挥发性成分组成差异。将所得精油进行体外抑菌试验比较三种方法所得精油对于供试菌的最小抑菌浓度(MIC)。结果显示三种方法均得到不同含量的醇、烃、酸、醛、酮、酯和酚类物质,其主要具有抑菌功能的挥发性物质为石竹烯、β-水芹烯、蒈烯和柠檬烯等。

Abstract: Essential oil from origanum vulgare L.was extracted by three different methods -water steam distillation,simultaneous distillation extraction,microwave assist water distillation and identified by GC-MS,intend to compare the differences among the three volatile compositions,then compare the MIC of Oregano oils extracted to five pathogen in vitro.The results shows that they all have alcohol,hydrocarbon,acid,aldehyde, ketone,ester and phenols but in different levels. The mainly antibacterial volatile contents were Caryophllene, beta- phellandrene, careen,cyclohexane and Limonene.
