Abstract

Using experiment of single factor and orthogonal method to optimize the extraction process of flavonoids from Sweet tea by alcohol extraction,ultrasonic extraction,microwave extraction and enzymatic extraction.The result shown that the optimum conditions of ultrasonic extraction are:50%(v/v) ethanol concentration,solid-liquid ratio 1:40,52 W of ultrasonic power,extraction time 30 min,and temperature 40 ℃.Under such condition,the yield of flavonoids compound was 12.69%.
