In order to evaluate the bioactivity of ‘Agakong3’, which was newly bred, quinone reductase (QR) inductiveactivity and antioxidant activity were both assessed. The methanol extract of ‘Agakong3’ showed a significantly stronger QRinductive activity than other soybeans. The methanol extract of ‘Agakong3’ also showed a significantly stronger cytotoxicityon hepa1c1c7 than other soybeans. ‘Agakong3’ exhibited the most potent antioxidant activity in the Trolox equivalentantioxidant capacity (TEAC) assay whereas it showed significantly weak antioxidant in the DPPH assay. In total phenol andflavonoid contents, ‘Agakong3’ showed the highest contents regarding phenol and flavonoid compounds. Major isoflavonessuch as daidzein and genistein were quantitified by high performance liquid chromatography. ‘Agakong3’ also showed thehighest total isoflavone contents. Results of correlation analysis showed that there were high correlation coefficients betweenthe contents of isoflavone and TEAC and the contents of isoflavone and QR inductive activity, respectively. These resultssuggest that ‘Agakong3’ will be a promising and functional food material.
