Abstract
Aglycones compounds were extracted from Korean soybean by sub/supercritical water. The various experimental variables were the temperature and pressure of sub/supercritical water. The extracted sample was analyzed by reversed-phase high performance liquid chromatography (RP-HPLC). Aglycons were selectively extracted at the experimental condition of $200^{\circ}C$ and 200 bar of subcritical water. It was also experimentally observed that almost the same amount of aglycones, $0.9{\mu}g$, was extracted from 5 g of Korean soybean at $400^{\circ}C$ and 250 bar of supercritical water.
