High relevanceGRIFOLA FRONDOSA-DERIVED SUBSTANCE HAVING ANTI-INFLUENZA VIRUS ACTIVITY AND METHOD FOR PRODUCING THE SAME
Grifola frondosa
Key points
- This invention is intended to discover a fraction having strong anti-influenza virus activity via M[phi] activation in the Grifola frondosa extract or an active substance distributed therein to develop a simple and effective production method and to use such fraction for food and beverage products, pharmaceutical products, feeds or feed additives, and the like
- This is realized by treatment of maitake mushrooms with a molecular sieve apparatus, such as an ultrafiltration apparatus or gel filtration apparatus, to isolate glycoprotein-containing fractions or sugar-protein complex-containing fractions having molecular weights of 30,000 to 100,000, so as to minimize the influence on substances having strong anti-influenza virus activity and contaminants
