Recently, researchers from the Nutrition Department of the Affiliated Hospital of Qingdao University Medical College published a paper to explore the best conditions for ultrasonic extraction of Flavonoids from winter jujube It was pointed out that the technology parameters of ultrasonic assisted extraction of Flavonoids from winter jujube were optimized This article was published in the Journal of the Medical College of Qingdao University in 2014 Taking the antioxidant activity of Dongzao extract (dje) as an index, the effects of ultrasonic extraction time, material ratio and extract concentration on the extraction rate of flavonoids were studied, and L9 (34) orthogonal test was designed on the basis of single factor test The best technology of ultrasonic extraction is: the ratio of material to liquid is 1:25, the volume fraction of ethanol is 0.70, and the extraction time is 30 minutes.
