The invention is a novel multi-organ storage protective solute, which belongs to the organ transplantation section in the biomedicine technique field. The organ transplantation has the critical step of organ storage which decides the success or failure of transplantation. The phenomena of ischemia and reperfusion during organ storage lead to mass generation of free radicals which cause the oxidative damage to the stored organ. The invention creatively applies an anti-oxidation system composed of melatonin, vitamin C and water miscible vitamin E for reducing the oxidative damage caused by free radical generation during organ storage; mannitol is used to maintain the solution osmotic pressure and reduce the solution viscosity; and light concentration glucose is used for meeting the lowest metabolism requirements of the organ. The experiment shows that the multi-organ storage effects of the invention are superior over the organ storage solution (UW liquid) widely applied worldwide and nationwide currently. The invention is used for storing the off-body kidney, liver, pancreas, heart and lung before transplantation, thereby extending the effective storage time, increasing the transplantation success rate and offering chances of organ transplantation for more patients.
