dark condition Manufacturing method of soybean leaves of the higt-content isoflavone derivatives in dark condition and soybean leaves of the higt-content isoflavone derivatives using the same

摘要

The present invention relates to a method for producing soybean leaves having a high content of isoflavone derivatives under dark conditions, and to soybean leaves having a high content of isoflavone derivatives prepared by the method. Specifically, when a certain concentration of ethylene is treated in a soybean plant 20 to 60 days after sowing under dark conditions, isoflavone derivatives are more effective than in the case of treatment with etepone under light conditions requiring a high level of energy. It was confirmed that it was accumulated at a high concentration in soybean leaves. Therefore, when the method of the present invention is used, soybean leaves containing very high isoflavones can be produced economically and quickly, and the soybean leaves, extracts of soybean leaves, and extract fractions containing a high content of isoflavone derivatives are effective in estrogen imbalance and lack of antioxidant activity. It can be usefully used as food and pharmaceutical material for induced diseases.
