桂西艾叶总黄酮的超声波提取工艺研究

Study on extracting processing of the total flavanone of Guixi's folium artemisiae argyi by ultrasonic wave

探讨艾叶总黄酮的提取及鉴别方法。采用超声波乙醇浸提法从艾叶中提取黄酮类物质,对所提取的黄酮类物质进行验证,并用分光光度法测定含量。测得样品中总黄酮的含量C=0.6599mg/ml,回收率为102.6%,其纯度和产率均较高。方法采用全物理过程,无任何污染,是提取艾叶黄酮类物质的有效途径。

In order to make use of the resources of folium artemisiae argyi , avoid wasting and approach the extraction of total flavanone of folium artemisiae argyi. The flavonids were extracted by ethanol as the solvent from folium artemisiae argyi with ultrasonic wave and ethanol extraction. Using spectrophotometry to extract and check the flavanone of folium artemisiae argyi. By this method getting the density of the total flavanone of folium artemisiae argyi is C = 0. 6599 mg/ml and the rate of recovery is102.6 %. This text provides the extraction and purifying methods to get the outcome and the purity of the flavanone are all very high . This method is a purely physical process and has not any pollution. It is an ideal way to extract the flavanone of folium artemisiae argyi
