摘　　要：以柚子籽为原料,采用乙醇为提取剂,通过单因素试验和正交试验,确定了提取柚子籽中黄酮类化合物的最佳工艺。试验结果表明,各因素影响柚子籽黄酮类化合物提取的程度由大到小的顺序依次为料液比,乙醇浓度,提取时间,提取温度。提取的最佳工艺参数为乙醇浓度70%、料液比1:40(g/mL)、提取温度70℃、提取时间5h。在此条件下,柚子籽黄酮类化合物的提取率为0.968%。Extracting flavonoids from grapefruit seed and the effects of extraction conditions on extracting yield were studied.The optimal conditions of the extraction process were obtained by orthogonal experiments as follows： 70% ethanol with 40：1 ratio of solvent to the seeds extracting 5h at 70℃.The extracting yield was 0.968% on the optimal conditions.
