摘要
为提取具有生理活性和药用价值的大豆皂苷 ,以脱脂大豆为原料 ,用乙醇浸提、正丁醇萃取、丙酮沉淀法提取大豆中皂苷 ,通过紫外光谱法检测大豆皂苷的含量和纯度 ,得出提取大豆皂苷的最佳条件为温度 80℃ ,乙醇浓度 70 % ,浸泡时间 7h。大豆皂苷的提取率为 94%。
We used soybean seeds as raw material to extract physiological and curatorialthe soybean saponin. Crude saponin was obtained from soybean seeds by the method of alcoholl extraction and acetone precipitation. The content and purification of soybean saponin were determined by UV. The optimal condition of extraction is 70% alcohol,80?℃ and 7?hour.The yield of saponin is 94%.
