Using Sedum spectabile boreau flowers as raw material, single factor and Box-Behnken response surface test were used to optimize the extraction conditions of Sedum spectabile boreau flavone assisted by ultrasonic enzymatic method, and the antioxidant activity of Sedum spectabile boreau flavone was analyzed in vitro. The results showed that the optimal extraction conditions of total Sedum spectabile boreau flavonoids were ultrasonic action time of 60 min, ethanol concentration of 35%, liquid-solid ratio (ml /g) was 20:1, and the amount of enzyme (cellulase: pectinase =1:1) was 3.2g.The study on the antioxidant activity of total flavonoids of Sedum spectabile boreau flower showed that its antioxidant capacity was gradually enhanced with the increase of the mass concentration of the test, which had a certain dose-effect relationship.
