摘要: 旨在采用超声波辅助法提取米口袋中总黄酮并对工艺进行优化。在单因素实验的基础上,确定料液比、超声温度、超声功率、超声时间4个因素的Box-benhnken的实验设计。以总黄酮的提取率为响应值,采用响应面法优化米口袋总黄酮的提取工艺,建立并分析各因素与指标值的数学模型。最佳工艺参数为:料液比1:40 g/mL,超声温度45℃,超声功率300 W,超声时间60 min,总黄酮提取率理论值为8.08%,实际值为8.22%,相对标准偏差为0.33%。本实验方法具有操作简便、提取时间短和成本低等优点,可为后期米口袋的研究提供理论依据。

Abstract: Objective: Establish a method of ultrasonic assisted extraction of flavonoids in Gueldenstadetia verna. Method: The whole plant of Gueldenstadetia verna as experimental material, do experiment by selecting four single factors: solid-liquid ratio, ultrasonic temperature, ultrasonic power, extraction time, on this basis, through these four single factors as the independent variable and the yield of total flavonoids of Gueldenstadetia verna as response values, design the response surface optimization method of four factors three levels. Results: The best process parameters for optimization analysis are as follows: ratio of solid-liquid 1:40 g/mL, ultrasonic temperature 45 ℃, ultrasonic power 300 w and ultrasonic time 60 min. The actual value was 8.0795 %, compared with the theoretical value 8.2195 %, the RSD was 0.33%. Conclusion: This experiment method have advantages of simple operation, short extraction time, solvent recovery and low cost, and the component have the advantages of quality, less solvent residue.
