洋槐花中总黄酮物质的提取工艺的研究

采用传统浸提法，以乙醇为溶剂，考察溶剂浓度、提取温度、料液比、提取时间和提取次数对洋槐花总黄酮物质提取率的影响，并在单因素实验的基础上，通过正交试验，确定了洋槐花总黄酮物质的提取工艺。结果表明，乙醇浓度、提取温度、料液比、提取时间及提取次数对洋槐花总黄酮物质的提取率均有影响，优化的洋槐花总黄酮物质的提取工艺为：料液比1：25，乙醇浓度70％，提取温度60℃，提取时间90min，提取次数为三次。

The total flavones were extracted with alcohol as the solvent from SophoraJaponica.L.The effects of the extraction conditions such as the concentration of ethanol,the extraction time, the solid-liquid ratio,extraction temperature and the extraction times were studied. The proper condition was determined by orthogonal experiment.The results were as following： the solid-liquid ratio was 1：25,The extraction temperature was 60℃,the extraction time was 90 min, the concentration of ethanol was 70%, and the extraction times of Sophora Japonica.L was three.
