摘要
采用水蒸气蒸馏法和超临界二氧化碳萃取法获得了蜂胶挥发油。GC-MS分析并鉴定出50种化合物,两种提取方法所得蜂胶挥发油在成分组成上存在显著差异。抑菌实验表明,两种提取方法获得的挥发油对金黄色葡萄球菌、枯草芽孢杆菌、铜绿假单胞菌具有很强的抑制作用,而超临界法萃取的挥发油的抑菌效果强于水蒸气蒸馏法。
In this work,propolis essential oil was obtained by steam distillation extraction and supercritical CO2 extraction,respectively.Added together,50 components in resulting propolis essential oils were identified by GC-MS method.Propolis essential oils extracted by both methods exhibited strong inhibition effects against Staphylococcus aureus,Bacillus subtilis and Pseudomonas aeruginosa in vitro.Stronger inhibition effect of propolis essential oil extracted by supercritical CO2 extraction on the three species of bacteria than that of propolis essential oil extracted by steam distillation extraction was observed.
