Abstract: The content of seed protein, fat and soybean isoflavone were measured, prolamine, gobulin and glufelin in the seed storage protein were ext racted in turn. The results analyzed by SDS-PAGE were as follows: Among the varieties tested, 7 were high in protein, 4 high in fat, 6 high in isoflavone, 2 high in protein and isoflavone, 1 high in fat and isoflavone, 1 high in protein, fat and isoflavone.By SDS-PAGE of seed storage protein, 4 were found to be high quality in protein, and 2 were special varieties for tohu and one for young soybean. Measurement of protein, fat and isoflavone connected with SDS-PAGE could be a handy and quick method for finding varieties that had high quality in protein.

Key words: Soybean, Varieties, Protein, Fat, Isoflavone
