Study on Ultrasonic Wave Extraction Process of Total Flavones From Fructus Forsythia
The optimal process of extracting total flavonoids from Fructus Forsythia was studied by single factor test and orthogonal test. The absorption of total flavonoids was determined by uv-spectrophotometry and the standard curve was used to calculate the content. The results showed that the optimum conditions for extracting the total flavonoids assisted by ultrasonic wave are as follow: 60 %ethanol
ultrasonic time 15 min and ultrasonic temperature 60℃.The optimazed method is stable and efficient
the rate of total flavonoids extracted is up to2.58%
