Bean leaves or bean stems having high isoflavone derivatives content and method for preparing same

摘要

The present invention relates to soybean leaves or soybean stems having high isoflavone derivative content, and a method for preparing the same. Specifically, by finding that soybean leaves or soybean stems treated with ethylene and ethephon, i.e. a ethylene donor, show significantly increased isoflavone derivative content, the method for preparing the soybean leaves or soybean stems having high isoflavone derivative content and the soybean leaves or soybean stems having high isoflavone derivative content prepared by using the method can be useful as functional foods and medicinal materials for diseases due to estrogen imbalance and lack of the antioxidative activity.
