摘　　要：对20个不同大豆品种的种子蛋白质、脂肪以及大豆异黄酮含量进行了测定,并对种子贮存蛋白中的醇溶蛋白、球蛋白、谷蛋白分别进行了提取和电泳分析,从中筛选出7个高蛋白品种,4个高脂肪品种,6个高大豆异黄酮品种,2个高蛋白高大豆异黄酮的双高品种,1个高脂肪高大豆异黄酮的双高品种,1个高蛋白高脂肪高大豆异黄酮的三高品种。通过电泳分析得到4个优质蛋白品种,两个豆腐专用品种。将蛋白质、脂肪、大豆异黄酮含量的测定与电泳方法结合,可以成为筛选优质蛋白质兼用性品种的快速简便方法。The content of seed protein, fat and soybean isoflavone were measured, prolamine, gobulin and glufelin in the seed storage protein were extracted 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.
