Abstract:

The extraction conditions of gingerol with ethanol were studied. The optimum condition were studied to extract flavonoid by orthogonal experiment.The results indicated that using ginger as the material, under the condition of 80% ethanol, 50℃ temperature, 60-mesh screen, 1:10 solid-to-liquid ratio, 2-hour-extraction time, the extraction rate was the highestin this experiment, which was 1.61%.
