Abstract:Object: To investigating the optimum extracting conditions of the total flavones in Folium artemisiae argyi. Methods: The extracting conditions of the total flavones in folium artemisiae argyi by ultrasonic waves were optimized by the single-factor and orthogonal experiments. Using rutin as control reagent and aluminium nitrate as colorimetric reagent, the absorbency of total flavones was determined with colorimetric wavelength at 510 nm. Results: The best dipping time in 60% alcohol, ulgtrasonic wave power and extraction time were 24 h, 200 W and 40 min, respectively. Conclusions: The flavonoid compounds were in abundance in Folium Artemisiae Argyi and had strong anti-oxidant activity. The results also indicated a promising prospect fro development of Folium Artemisiae Argyi.
