Abstract
PURPOSE: The titled composition having improved shelf stability, safety to living body, productivity of industrial scale and economical advantage, comprising S- adenosyl-L-methionine, sulfate radical, and magnesium sulfate in a specific molar ratio.
CONSTITUTION: A white powder composition comprising S-adenosyl-L-methionine- L (referred to as SAM afterward), sulfate radical, and magnesium sulfate in a molar ratio of SAM: sulfate radical: magnesium sulfate of 1:(0.5W1):(2W6), preferably 1:(0.6W0.9):(3W5). An aqueous solution comprising given amounts of the three components is prepared and brought into contact with an organic solvent to be mixed with this aqueous solution, to precipitate the desired composition, or the aqueous solution is vaporized to dryness, to give the desired composition. A sulfate is used as SAM, when the amount of the sulfate radical is more than the given amount based on SAM in the aqueous solution of SAM sulfate, the aqueous solution is brought into contact with an anion exchange resin or magnesium hydroxide is added to it. When the amount of the sulfate radical is less than the given amount, a fixed amount of the sulfate radical is added to the aqueous solution to adjust it to a proper amount of sulfate radical.
