摘　　要：探讨八角黄酮超声辅助乙醇水二元体系最优提取工艺条件。考察了乙醇浓度、超声时间、料液比和超声功率等因素对八角黄酮得率的影响,通过响应面优化提高黄酮得率的超声提取条件。结果表明:乙醇浓度、超声时间、料液比和超声功率等显著影响总黄酮得率。优化出提高八角黄酮得率的最佳超声提取工艺:乙醇浓度73%,超声时间23min,料液比1∶45,在此条件下黄酮得率为9.43%±0.13%。To investigate the optimum extraction conditions for the yield of total flavonoids from star anise, four single factors such as ethanol concentration, ultrasonic time, solid to liquid ratio and ultrasonic power are studied in the study. The optimum ultrasonic extraction conditions for the yield of total flavonoids are optimized by response surface methodology. The results show that all the four parameters affect the yield of total flavonoids significantly. The optimum ultrasonic extraction conditions for the yield of total flavonoids from star anise are as follows： ethanol concentration is 73%, ultrasonic time is 23 min and solid to liquid ratio is 1 ： 45. Under these conditions, the yield of total flavonoids from star anise is 9.43%±0.13%.
