A novel diterpenoid erinacine, isolated from the cultured mycelia of Hericium erinacium, is known to have a potent stimulating effect on NGF synthesis.  The effects of erinacine and related compounds in the brain in vivo are not known.  Yokogoshi and Kawagishi reported that effects of erinacine A (from Hericium erinaceus) on the production of NGF and catecholamines which stimulate NGF synthesis in the brain of rats.

Grape King Bio is a manufacture of functional ingredients for the food, beverage, medical food and pharmaceutical industries.  We can use the fermentation technology to produce many kind of mushroom mycelium such as Antrodia camphorata, Ganoderma lucidum, Cordyceps, Coriolus versicolor, Phellinus linteus, Grifola frondosa, Hericium erinaceum, Lignosus rhinocerus and Armillaria mellea.  These kinds of extracts are mycelium products; they can be food additives and functional ingredients.  For the Hericium erinaceus mycelia, it is brown powder containing at less 8% active polysaccharide.
