Title: Optimization for Homogenate Extraction of Total Flavonoids from Glycyrrhiza Leaves by Response Surface Method
Abstract: 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%,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%.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.
