PURPOSE:To obtain a nutritive transfusion solution composition of amino acid not discoloring, having pharmaceutically sufficient stability containing no stabilizer comprising L-tryptophan as dipeptide or tripeptide. CONSTITUTION:A nutritive transfusion solution composition containing L- tryptophan as a dipeptide (e.g., L-tryptophyl-glycine, L-alanyl-L-tryptophan) or a tripeptide (e.g., glycyl-L-tryptophyl-glycine) and comprising essential amino acids. The dipeptide and tripeptide are stable to an aqueous solution, will not discolor after thermal sterilization, has improved water solubility, can optionally contain L-tryptophan component in high concentration and can prepare a transfusion solution of new prescription agreeable to purposes.
