    摘要: PURPOSE:To obtain tryptophan from an aqueous solution containing tryptophan together with other amino acids, by contacting the solution with a strongly acidic cation exchange resin beads, desorbing the other amino acids from the resin with an aqueous solution of an acid, etc., and then separating tryptophan with an alkaline aqueous solution. CONSTITUTION:An aqueous solution containing tryptophan together with other amino acids is made to contact with strongly acidic cation exchange resin beads filled in a column to effect the adsorption of tryptophan and a part of the coexisting amino acids, and the resin is made to contact with an aqueous solution of an acid or an inorganic salt to effect the desorption of the adsorbed coexisting amino acids. Thereafter, the adsorbed tryptophan is desorbed with an alkaline aqueous solution, and the desorbed solution is made to contact again with the resin. The adsorption and desorption are repeated to separate the tryptophan in the form of highly concentrated solution. EFFECT:An alkaline aqueous solution having a tryptophan concentration of 3-15wt% and free from impurity amino acid can be produced.

    摘要: NEW MATERIAL:A pyridoxamine compound shown by the formula I. EXAMPLE:( + or - )-15-Aminomethyl-14-hydroxy-5,5-dimethyl-2,8-dithia[9]( 2,5 )pyridinophane. USE:A reagent for synthesizing an optical active amino acid. Having high stereoselectivity. The possibility to prepare by products is lost, purification by distillation is possible, purification operation is easy, and a large amount of handling can be carried out. PROCESS:A pyridinophane shown by the formula II is treated with a hydroxylamine hydrochloride in the presence of a base, to give an oxime compound shown by the formula III. The oxime compound shown by the formula III is reduced with NaBH4, etc., to give a pyridoxamine compound shown by the formula I.
