NOVEL SUBSTANCE ORIGINATING IN BASIDIOMYCETE CULTURE, PROCESS FOR PRODUCING THE SAME AND USE THEREOF

摘要

A novel substance that has the physiological activity of the aglycone of isoflavones and the physiological activity of the culture of the basidiomycetes with the physiological activities being synergistically enhanced, obtained by cultivating a basidiomycetes having a beta -glucosidase activity in a medium containing an isoflavone, a method for producing it, and food, feedstuff and medicine containing it. The substance of the invention is improved in the physiological effect of the aglycone of isoflavones and the physiological effect of the culture of the basidiomycetes, and is not only useful as an anti-tumor agent but also is useful for therapy and/or prevention of osteoporosis and also as an immune enhancement agent.
