Soybean [Glycine max (L.) Merrill] is one of the world’s most major crops as not only an important source of oil and protein, but also secondary metabolites. Intake of soybean is associated with decreased risk of cardiovascular disease and osteoporosis, as well as cancer, including breast and colon cancers. Seventy soybeans germplasms collected from 4 different countries, America (6 varieties), China (15 varieties), Japan (16 varieties), and Korea (33 varieties), were distributed by Chungbuk National University (Cheongju, Chungbuk, Korea) and cultivated in Konkuk University farm. This study investigated the isoflavones in seventy soybeans according to 4 different origins (America, China, Japan and Korea). Between 4 different origins, Korea showed highest concentrations of total isoflavones (1292.6 ± 438.6 ㎍ g-1) and China showed the lowest concentrations of total isoflavones (843.8 ± 365.7 ㎍ g-1). The total isoflavone contents in soybean of America and China ranged from 572.3 ㎍ g-1 to 2001.9 ㎍ g-1 and from 275.8 ㎍ g-1 to 1521.8 ㎍ g-1, respectively. And the isoflavone contents of Japan and Korea ranged from 473.3 ㎍ g-1 to 2314.6 ㎍ g-1 and from 419.0 ㎍ g-1 to 3010.7 ㎍ g-1, respectively. Malonylgenistin (356.9 ± 158.8 ㎍ g-1) was the major isoflavones among 12 isoflavones. Specially, glycoside and malonylglycosides constituted 49.2 % and 45.3 % of total isoflavones in soybeans, respectively.
