| Abstract: | The extraction of general flavonoids from sweet potato stem with ethanol was investigated. Researches the influence factors to the extraction of general flavonoids. The optimum technological parameters of extracting general flavonoids are as the following： the concentration of ethanol, the extract temperature, the ratio of solid to liquid and extracting time are 50 %, 80℃, 1 ： 20 and 3 hours, respectively. The extraction yield of general flavonoids under the conditions is 74.6 %. |
