The invention discloses a preparation method and application of monobutyryl adenosine cyclophosphate or salt thereof. The preparation method comprises the following steps: in the preparation process of the monobutyryl adenosine cyclophosphate disclosed as Formula I, carrying out acylation reaction on adenosine cyclophosphate and n-butyric acid anhydride in an aprotic solvent in a gas protective atmosphere under dark conditions by using an organic alkali as a catalyst, mixing the acylation reaction solution with water, and carrying out hydrolysis reaction; and in the preparation process of the monobutyryl adenosine cyclophosphate salt disclosed as Formula I, after preparing the monobutyryl adenosine cyclophosphate disclosed as Formula I in a polar organic solvent, reacting with alkali metal salt or alkali earth metal salt. The invention also discloses application of the monobutyryl adenosine cyclophosphate or salt thereof in drug quality control of dibutyryl adenosine cyclophosphate or salt thereof. The preparation method is simple to operate, can obtain the high-purity monobutyryl adenosine cyclophosphate or salt thereof, and can control the quality of the dibutyryl adenosine cyclophosphate drug.
