Soya saponins and isoflavones are main secondary metabolites in soyabeans. The content of these secondary metabolites in genetically modified (GM) and non-GM soyabeans were compared. Extracts from 6 cultivars each of GM and non-GM soyabeans were obtained using methanol. Each extract was partitioned with aqueous methanol and hexane and the aqueous methanol fraction was partially purified using HP-20 and LH-20 column chromatography to obtain crude soya saponin and isoflavone fractions.
