Abstract
The extraction of flavonoid was studied in this paper.The single factor experiment and the orthogonal experiment were used to determine the optical condition of extraction of flavonoid from the ginger.The extraction temperature,extraction time,ethanol concentration,and the solid-liquid ratio were selected as the main factors in this paper.The results showed that the optical condition of extraction is as following:extraction temperature 70℃,extraction time 5h,ethanol concentration 80%,and the solid:liquid ratio 1:25.
