中文摘要:

艾叶中富含精油以及多糖、黄酮等多种功能性成分。采用水蒸气蒸馏法提取艾叶精油，通过正交试验优化水蒸气蒸馏提取精油的工艺条件；GC-MS分析精油成分，同时考察了对应水提液中多糖和黄酮的含量变化，并通过菌落计数法比较艾叶精油和水提液的抑菌效果。结果表明，精油抑菌能力强，水提液抑菌能力一般。

英文摘要:

Folium Artemisiae argyi is rich in essential oil and various functional components，such as polysaccharides and flavones. The essential oil was extracted from Folium Artemisiae argyi using steam distillation. The extraction conditions were optimized by orthogonal analysis. The essential oil components were analyzed by GC-MS. The changes of polysaccharides and flavones contents in the water extraction were also investigated. The antibacterial activity of the essential oil and water extraction was compared using colony-counting method. The results indicated that the antibacterial activity of the essential oil was quite strong，while the water extraction was just an ordinary bacteria inhibitor.
