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

摘要

A novel substance which is obtained by culturing a basidiomycete having a β-glucosidase activity in a medium having a material containing isoflavones, comprises the aglycons of the isoflavones and the culture product of the basidiomycete, and has synergistically enhanced physiological activity of the aglycons of the isoflavones with physiological activity of the basidiomycete; and foods, feeds and drugs containing the same. Because of having the synergistically enhanced physiological activity of the aglycons of the isoflavones and the physiological activity of the culture product of the basidiomycete, the above-described substance is useful not only as an antitumor agent but also as a remedy and/or preventive for osteoporosis and an immunopotentiating agent.
