Quality and stability study results The reduced glutathione for injection prepared in the above examples 1 to 4 was taken, and the quality and stability thereof were investigated, TABLE 1 quality comparison table As can be seen from the above table, the reduced glutathione for injection prepared in the above examples has the required properties, the pH values of all batches of samples before and after freeze-drying are basically consistent, the reduced glutathione for injection prepared in example 3 has a lower loss on drying, and the reduced glutathione for injection prepared in example 1 has a higher loss on drying
