The finest single factor conditions were found and were used to optimize gingerol extraction method by orthogonal test. The results indicated that using ginger as the material, under the condition of 80% ethanol, 50℃ temperature, 60-mesh screen, 1:10 solid-liquid ratio, 2-hour-extraction time; the extraction rate was the highest in this experiment, which was 1.61%.
