Methods: The orthogonal design was used to optimize the extraction process of polysaccharide. The anthrone-sulfuric acid method was used to determine the content of polysaccharides in different extraction conditions and the oxidation resistance test and the free-radical clearance test were conducted. Results and Conclusion: Through the analysis of the test results, the optimum process was as follows. The 3 g dried Cerasus serrulata petals were put in the beaker with 240 mL distillated water and were extracted for 3 hours in the 90 ℃ water bath pot to obtain the supernatan
