| Abstract: | The naringenin as reference standard, the total flavones content in folium artemisiae argyi was determined by UV spectrophotometry at 290nm.The naringenin has a good linear relationship in the range of 1-8μg/mL,the total flavones content in samples is 1.186 % calculated by naringenin, the recovery is 101.5%.The method is simple, rapid, accurate and has good reproducibility,which can be used to determine the content of total flavones in folium artemisiae argyi. |
