Study on Ultrasonic Wave Extraction Process of Total Flavones from Forsythiae Fructus
Objective: To establish optimal process of extracting total flavonoids from Forsythiae Fructus by single factor test and orthogonal test. Method : The absorption of total flavonoids was determined by uv-spectrophotometer and the standard curve was used to calculate the content. Result : The optimum conditions for extracting the total flavonoids assisted by ultrasonic wave were as follow: 65% ethanol
ultrasonic time 15 min and extraction temperature 60 ℃. The mass fraction of total flavonoids extracted was up to 2.58%. Conclusion : The optimum extraction process was simple
