Effects of the Extraction of Essential Oil from Folium A. argyi on the Activity Components of the Related Water Extraction and the Comparison of Their Antibacterial Activity

Abstract:

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.
