Abstract

The extraction and separation of isoflavones from Korean soybean were peformed by various mechanical and chemical extraction methods. They included solvent extraction, stirring, supersonification and sub/supercritical water extraction. From the experimental results of the variation of solvent extraction by change in composition, the increase in extraction of a specific compound by stirring or supersonic energy, and the application of supercritical fluid with superior solvating power over solvents, the sonification was the most desirable extraction method in extracting aglycone isoflavones, daidzein and genistein from Korean soybean.

토종콩으로부터 비배당체 이소플라본을 추출하기 위한 다양한 기계적 및 화학적 방법을 적용하였다. 용매추출법의 침적과 교반, 초음파에너지와 아임계/초임계 수 추출이 포함되었다. 용매의 조성에 의한 추출효율의 증가, 교반에 의한 특정성분의 추출효과의 증대, 초음파에너지에 의한 추출성능의 개선, 용매보다 용해력이 좋은 초임계유체의 적용에 관한 실험을 수행한 결과에 의하면 비배당체 이소플라본의 추출은 초음파에너지에 의한 것이 가장 우수하였다.
