摘要
探讨超声波法提取食用仙人掌总黄酮的优化工艺。试验以芦丁为标准品,采用比色法测定总黄酮的含量,用单因素试验和正交试验方案优化超声提取条件。结果表明,超声提取食用仙人掌总黄酮的最佳工艺条件为：超声功率为最大超声功率（650W）的65%,料液比1/15（g·mL^-1）,提取时间30min和乙醇体积分数80%。
To establish the approach for the optimization of the ultrasonic-assisted extraction of total flavonoids from edible cactus.Methods：developing a colorimetric methods for determining the total flavonoids,comparing with the standard of rutin,and optimizing the methods by using single factor and orthogonal array.Results：the optimum methods were found to be：the biggest power of ultrasonic is65%（based on 650W）,solid-to-liquid ratio is 1 /15,extraction time is 70 min and ethanol concentration is 80%.
