摘要
通过响应面法分析并优化了甘草叶总黄酮的闪式提取工艺,确定最佳工艺条件为:乙醇体积分数70.2%、液固比40.3∶1、提取时间5 min,在此工艺条件下总黄酮的提取率高达2.91%,与模型预测值基本相符。结果表明闪式提取法是一种高效、快速提取甘草叶中总黄酮的方法。
The homogenate extraction technique of total flavonoids from Glycyrrhiza leaves was analyzed and optimized by response surface method. The optimum extraction conditions were confirmed as follows:volume fraction of ethanol of 70, 2%o ,ratio of liquid to solid of 40.3 : 1 and extracting time of 5 min. Under such conditions,the extraction rate of total flavonoids was up to 2.91%0. The experimental values agreed with the predicted values. Homogenate extraction was proved to be a kind of efficient and rapid method for extraction of total flavonoids from Glycyrrhiza leaves.
