【摘要】 采用乙醇提取法对草豆蔻(Alpinia katsumadai Hayata)中总黄酮的提取进行了研究,探讨了各种因素对总黄酮提取的影响,并用正交试验对总黄酮提取工艺进行了优化。结果表明,最佳的提取工艺条件为温度70℃、时间2.0 h、料液比1∶24(m/V,g∶mL)、乙醇体积分数70%,在此条件下总黄酮提取率为5.976%。更多还原

【Abstract】 Total flavones were extracted from Alpinia katsumadai Hayata by alcohol extraction method.The effects of solvent,temperature,time,and material to liquid ratio were studied;and the extraction technology was optimized by orthogonal design.The results showed that the optimized extraction conditions were,volume fraction of alcohol,70%;extraction temperature,70 ℃;extraction time,2.0 h;material to liquid ratio,1∶24(m/V,g∶mL).The yield of total alkaloid under these conditions could reach up to 5.976%.更多还原
