NOVEL DERIVATIVE OF FLAVONE C-GLYCOSIDE AND COMPOSITION CONTAINING THE SAME

摘要

It is intended to provide a novel flavone C-glycoside derivative or its salt showing, in particular, an antiallergic effect and a composition containing the same. Allergic diseases have been increasing in the recent years. Among all, pollenosis and atopic dermatitis are remarkably increasing to thereby result in social problems. Flavones and glycosides thereof, which are reported as having an effect of inhibiting the release of histamine from adipocytes and an immunosuppressive effect, are expected as being applicable as remedies for allergy. However, most of flavones should be taken in a large dose to exert the effects and, therefore, it has been urgently required to find out a compound exhibiting the effects at a smaller dose. Under these circumstances, it is intended to provide a novel component whereby allergic diseases can be treated in a small dose and a composition containing the same.
