Classification and discrimination of Soybean (Glycine max (L.) Merr.) genotypes based on their isoflavone content

Abstract Isoflavones are phytoestrogens with various types of biological activity. Soybean (Glycine max (L.) Merr.) is the most abundant source of isoflavones in human nutrition. The present study aims to classify the different soybean genotypes according to their isoflavone contents. HPLC analysis of isoflavone content in 22 soybean genotypes was performed. The average content of individual isoflavones in the genotypes analyzed ranged from 2.8 μg/g to 1069,9 μg/g while the most abundant component among the 22 genotypes was malonyl-genistin. The majority of isoflavones had a significantly higher concentration (p
