Abstract:
Taking licorice as material,the best technological conditions of flavonoids compounds from licorice was studied with ethanol extraction method.In the research,the optimal processes for extracting flavonoids compounds from licorice were investigated by four single factors:extraction time,extraction temperature,liquid ratio and concentration of ethanol,combined with the analysis of response surface software Design-Expert 8,which made a optimal design on four influence factors to determine the best technological conditions of flavonoids compounds from licorice.The results showed that the optimum extraction conditions of flavonoids compounds from licorice were the ethanol concentration 71.02%,the solid-liquid ratio 1∶32.83 g/mL,the extraction time 2.97 h,the extraction temperature 70.04℃.Under these conditions,the extraction rate of flavonoids compounds from licorice was 1.328%.
