S-Adenosyl-L-methionine compositions and production thereof

摘要

S-adenosyl-L-methionine compositions stabilized against decomposition of S-adenosyl-L-methionine comprising S-adenosyl-L-methionine, a sulfuric acid equivalent and a nucleoside sulfate, which are produced from a solution comprising the three essential components in an aqueous solvent by, for example, adding thereto a water-miscible organic solvent thereby to precipitate the composition (process A) and/or by evaporating the aqueous solvent off the solution (process B).
