This study was conducted to further characterize mucilages from Dioscoreae Rhizoma, which have been known to be proteoglycans. We chose the two types of yams, Dioscorea batatas Dec. (club-like) and D. Japonica Thunb. (cane-like). Repeated gel filtration of a dialyzed water extract of each fresh yam on Bio-gel P-100 and then Sephadex G-150 columns completely separated the mucilage from protein. Furthermore, gel filtration of a water extract from each yam processed by steaming and drying on the Bio-gel P-100 column gave only one polysaccharide peak
