Daily intake of isoflavones based on the market basket method

摘要: Daily intake of isoflavones (daidzin, glycitin, genistin, daidzein, glycitein, and genistein) was determined quantitatively, based on the market basket method. Acid hydrolysis during extraction foods chosen to convert phytoestrogenes into respective aglycons, facilitating HPLC analysis allowing quantitation total as aglycones including both originally present glycosides "free" aglycones. The were extracted from samples with methanol by reversed-phase using a linear gradient methanol-water eluent. From results hydrolysis, daily isoflavon 38.1 mg/adult Japanese. values obtained method National Nutrition Survey similar.
