The two-dimensional paper-chromatography was applied to the detection of peptides in the fractionates of X-4,X-2,X-1,and the effluents were separated from Sake with molacular screen using ion exchange resin, Dowex-50.As the results, the authors have recognized that they are polypeptides and can be classified into 3 groups as follows : 1) polypeptides containing many amino acids composing protein, except the rareness or absence of histidine and arginine; 2) polypeptides rare or absent of leucine and valine; 3) polypeptides especially rich in aspartic acid, glutamic acid, glycine and serine. Moreover, a polypeptide containing γ-amino-butyric acid was found.And a few quantities of glucose, galactose and mannose were found in X-1 fractionate hydrolyzed.
