Abstract:
The extraction technology of ginger flavonoid from ginger peel with alcohol soaking was studied in this paper. The optimal extraction technological conditions of ginger flavonoid were obtained by single factor and orthogonal experiments. The results showed that the optimal extraction conditions of ginger flavones were alcohol concentration75%, temperature 60 ℃, ratio of materials to solvent 1:45 and extracting times 5.5 h, under which the yield of ginger flavonoid reached 0.61%.
