For the systematic investigation of biochemical characteristics of Korean ginseng protein by years, protein fractions were analyzed by the techniques of polyacrylamide gel electrophoresis, sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and gel filtration, while the amino acid composition was studied by amino acid autoanalyzer. In the amino acid composition of water extracted protein and main fraction of gel filtration, arginine content was the highest, 47.17% in water extracted protein and 57.36% in main fraction followed by glutamic acid and asparatic acid. On the contrary, cystine and methionine contents were very low in both cases
