摘　　要：采用乙醇溶液浸提、水溶液浸提、乙醇抽提三种方法提取苦荞麦籽壳中的黄酮类化合物。结果表明:乙醇溶液浸提的最佳提取工艺条件是:浸提温度为70—75℃,乙醇浓度为60%,浸提时间为6h,乙醇用量为原料的10倍;水浸提的最佳工艺条件是:温度70—75℃,浸提时间为2h,水用量为原料的20倍;乙醇溶液抽提的最佳工艺条件是:95%的乙醇回流抽提6h。Three approaches were used to extract flavonoids from the shells of Tartary Buckwheat.The results have indicated that 70-75℃,10:1of 60% ethanol:shells,extraction 6h were the best conditions for ethanol extraction;70-75℃,20:1of water:shells, extraction 2h were for water extraction and 95% ethanol extraction 6h were the best method ethanol recollection.
