Dihydroibotenic acid

Tricholomic acid erytAro-dihydroibotenic acid, a compound isolated from the Basidiomycete Tricholo-ma muscarium. It can also be prepared by reduction of ibotenic acid. It possesses flavor promoting activity similar to, but much more active than, that of sodium glutamate. It also has a synergistic effect on the flavor improving property of inosinic acid and guanosine S -phosphate. 

Amanitas, such as fly agaric (Amanita muscaria), contain a toxic derivative of isoxazole known as ibotenic acid (2-57), which is biosynthesised from glutamic add. Hallucinogenic effects also shows its dihydroderivative tricholomic (dihydroibotenic) acid (2-58), which is a component of Tricholoma muscarium mushrooms (see Section 10.3.2.9.3).
