Abstract—The corn embryo was taken as raw material to centrifugal and freeze-dried until use [4,5]. (TG16-type
extract glutathione, and the antioxidant activity of reduced Changsha Intentia Instrument Co., Ltd.).
glutathione was studied. The result indicated that the glutathione
had strong elimination ability to free radicals. Total antioxidant 2) Detection of GSH by UV spectrophotometry
