[Abstract]
A method for the determination of isoflavone content in the transformed progenies of soybean by HPLC was reported.Using unisil Q C 18 column (4.6 mm×250 mm, 5 μm), with a mobile phase of CH 3CN 0.003 mol/L Na 2HPO 4 (17:83), a detecting wavelength at 254 nm, and flow rate of 1 0 mL/min, it was found that the contents of daidzein, genistein, daidzin and genistin in the transformed progenies of soybean changed greatly and could be separated effectively, which makes it possible to cultivate and develop the best progeny for further development.
