We isolated and identified three representative isoflavones from soybean leaves. On the basis of the isolated isoflavones, the leaves of 14 Korean soybean cultivars were subjected to HPLC analysis. Jinpum 2 and Cheongja 1 cultivars showed high amounts of isoflavone, with the content of glycitein (2) being predominantly higher than those of daidzein (1) and genistein (3). Our results show these cultivars are important sources for development of better soybean leaves contains high quality breeding and nutritional value.
