The Extraction Technology of Total Flavonoids from Golden Tea by Ultrasonic Method
The research aimed to optimize the extraction technology of total flavonoids from Golden tea by ultrasonic method. The effects of four factors including ultrasonic time,ultrasonic power,ethanol concentration and material to liquid ratio on the yield of total flavonoids were investigated. The optimum technological conditions of total flavonoids extraction were confirmed through single factor experiment and the orthogonal experiment. The optimum extration conditions were as follows:ultrasonic time was 20 min,ultrasonic power was 75 W,ethanol concentration was 70%and material to liquid ratio was 1∶20,the yield of total flavonoids was 5.349 3%.
