摘要
为确定茶叶中黄酮类化合物的最佳提取工艺,选取提取时间、水浴温度、乙醇浓度和液固比4个影响提取效果的因素做单因素试验,并利用Design-Expert 6.0进行响应面分析试验。试验结果表明,提取茶叶中黄酮类化合物的最佳提取工艺条件为:时间60 min、水浴温度80℃、乙醇浓度为60%、液固比(V/V)为10。
This paper deals with the study on the extracting conditions of flavonoid from tea. Response surface methodology was used to obtain the optimum extracting conditions by Design-Expert 6.0. The research findings show that the optimum extracting conditions were as follows： extracting 60 min, water temperature 80 ℃, 60% alcohol, 10 times volumes.
