摘要
使用不同的溶剂从大豆异黄酮粗品中提取大豆黄苷。通过溶剂回流萃取及不同溶剂组合萃取实验确定了最佳的提取条件。结果表明 ,丙酮和乙酸乙酯的组合萃取可以将原料中大豆黄苷的含量提高 2 .5倍以上。最终可以得到纯度为 90 %的大豆黄苷产品 ,收率 4 0 %。产品再通过盐酸水解可以得到其相应甙元。
Daidzin is extracted from rough isoflavone with different solvents . The optimal condition of extraction is obtained through the experiments of the circumfluence extraction with different solvents and hybrid solvents. The result shows that, on over 2.5 times content of Daidzin in materials can be arrived with the hybrid extraction of acetone and ethyl acetate. Ultimately, Daidzin is obtained with a purity 90% and yield 40%.And its aglycone is attained through the hydrolysis of Daidzin with hydrochloric acid.
