Objective: To optimize ultrasonic extraction technology of total flavones from Prunus tomentosa.Method: Taking yield of total flavones as evaluation index
the content of total flavones was determined by UV
orthogonal test method was used to optimize ultrasonic extraction technology with extraction time
ratio of solid-liquid
the concentration of ethanol and ultrasonic power as factors
extraction condition of total flavones was optimized by response surface method.Result: The best extraction condition was:the concentration of ethanol 95%
ratio of solid-liquid 1∶20
ultrasonic power 400 W
extractive time 45 min
under this condition
average yield of total flavones could be up to 1.135%.Conclusion: Ethanol ultrasonic extraction was low consumption
common used and convenient
it could be widely used in extraction technology of Chinese herbal medicine.
