The invention relates to an organ preservation solution and a method for preparing the same. The method comprises the following steps of: (1) adopting double buffer pairs of citric acids and phosphates to enable the PH value of a solution to be maintained in a range of 7.5 to 8; (2) adding active ingredients such as adenosine, L-arginine, tryptophan, ligustrazine hydrochloride, reduced glutathione and the like and keep the solution stable; (3) to maintain a hypertonic property of the preservation solution with an osmotic pressure of 350-380 mOsm/L, adopting trehalose and gluconolactone as impermeable substances to effectively prevent cellular edema; and (4) adopting polyethylene glycol with a large molecular weight as a colloidal substance to effectively prevent extracellular space from expanding. Compared with the prior art, the method employs raw materials which are all homemade medicinal components and meet the standards of national pharmacopoeia, and are cheap and free of incompatibility; the organ preservation solution prepared is a colorless and transparent liquid which has stable properties, and can be sterilized by high temperature and high pressure, stored at normal temperature or low temperature, and refrigerated, and thus preparation, transportation, storage and usage of the organ preservation liquid are all very easy and convenient.
