| Abstract: | In this paper,ultrasound assisted method is used to extract total flavones from Trollius chinensis Bunge in Daxing'an Mountain Range.Aluminum nitrate colorimetric method is used to determined total flavone extraction rate.Taking temperature,solid-liquid ratio,volume fraction of ethanol and ultrasonic time as factors,the optimized extraction technology is obtained by the orthogonal test.The results shows that:the order of factors is:liquid ratio>ultrasonic time>temperature>volume fraction of ethanol,and the optimized extraction technology by ultrasonic-assisted extraction is as follows:the optimum extracting temperature 50℃,solid-liquid ratio 1:55,volume fraction of ethanol 75%,ultrasound time 40 min,extraction rate of total flavones from Trollius chinensis Bunge in Daxing'an Mountain extraction rate is up to 4.659%. |
