Study on Extracting Processing of Folium Artemisiae argyi and Anti-oxidant Activity

In this paper orthogonal experiment method was used to study the extraction process in(alcohol)-water system of folium Artemisiae argyi.Its contents of total flavonoids and total polysaccharides were measured by colorimetry.And it was found that different factors impacting on extraction were as followed: the concentration of alcohol,extraction temperature,extraction time and the ratio of materials for extraction liquid.The anti-oxidant activities of the extraction liquid were also studied by the chemical(luminescence) method.Results showed that folium Artemisiae argyi contains abundant of flavonoid and polysaccharide,and its extract possesses strong anti-oxidant activity.Therefore the researh and development of folium Artemisiae argyi are of great significance.
