1. The purified soybean hemagglutinin isolated from Korean soybean through the calcium phosphate column chromatography was found to contain mannose (4.9%) and glucosamine (1.1%) added to the pretein portion.
2. The fractions Ⅰ,Ⅱ,Ⅲ, the impurities accompanied by hemagglutinin during the final purification were proved to be new plant glycoproteins that were seemingly paper electrophoretically homogeneous and had the same mobility.
3. The carbohydrated and nitrogen contests of Ⅰ,Ⅱ,Ⅲ, were 4.5%, 1.13%, 1.1% in mannose, 0.5%, 1.2%, 1.22% in glucosamine and 12.8%, 15.5%, 13.9% in nitrogen respectively.
