The invention belongs to the field of chemical synthesis, and particularly relates to a preparation method of atropine sulfate. The preparation method comprises the following steps: firstly preparing tropine ester, then preparing atropine, salifying to prepare atropine sulfate, and finally refining to obtain the product. In the preparation process of the tropine ester, the reaction temperature is strictly controlled to be 105-111 DEG C, and the crystallization temperature is controlled to be 0-5 DEG C, so that the yield of the tropine ester is improved. In the process of preparing atropine through reduction reaction, palladium-carbon is adopted as a catalyst, and the reaction temperature is strictly controlled to be 10-15 DEG C, so that the product quality is effectively improved. Sulfuric acid is diluted by preparing a sulfuric acid ethanol solution, and the dripping speed of the sulfuric acid ethanol solution is controlled, so that the stable quality of atropine sulfate is ensured.
