Total Flavonoids fromStevia rebaudiana Residue：Optimization of Extraction Process by Response Surface Methodology and Antioxidant Activity Evaluation
研究甜叶菊残渣中总黄酮的提取工艺，同时测定甜叶菊残渣中总黄酮的抗氧化活性。首先以乙醇体积分数、超声功率和超声时间为因素进行单因素试验，找到每个因素的较优水平，然后在此基础上采用Box-Behnken法进行试验设计，并进行响应面分析，得到提取工艺的数学模型，预测出最佳提取工艺及最高总黄酮浸提量。结果显示：甜叶菊残渣中总黄酮物质的最佳提取工艺为乙醇体积分数70%、超声功率420 W、超声时间42 min，此时总黄酮浸提量为5.928 mg/g，与由数…查看全部>>
In this experiment, we optimized the conditions for extracting total flavonoids from stevia (Stevia rebaudiana) residue left after stevioside extraction and determined the antioxidant activity of the total flavonoids. Firstly, we selected ethanol concentration, ultrasound power, and ultrasound treatment time as factors to conduct single factor investigations for the purpose of establishing the appropriate levels for each of these factors. Then, we developed …查看全部>>
