| Abstract: | A process for extracting isoflavones by alcohol-water system from soybean germ was studied in this paper. And through single factor extraction tests and L9 (34)orthogonal experiments found the optimum extracting conditions of this system:solvent 80% ethanol, sample and extractant ratio 1 : 20, temperature 60 C, number of extraction 2, time 2 h. Under this condition, the obtainment rate of isoflavones from soybean germs is 1. 403%. |
