Yam has always been a high-quality food source for both medicinal and edible purposes.By conducting chromatographic analysis on the active ingredients of two types of yams,this paper compares the active ingredients of the two types of yams,and analyzes the clinical effects of different yams through historical literature.Finally,the paper discusses which is better between Dioscorea opposite Thunb and Iron yam(Dioscorea opposita Thunb.cv.Tiegun)as medicine and food.The paper ultimately concludes that the saponin content of Dioscorea opposite Thunb is higher and more suitable for medicinal use,while the saponin activity of Iron yam is lower and more suitable for daily diet.
