摘　　要：以染料木黄酮为对照物,通过对单因素实验和正交实验的比较,确定了从脱脂大豆粕中提取大豆异黄酮的最佳条件,为工业提取大豆异黄酮提供了参考依据。提取的最佳条件为乙醇浓度75%、浸提时间6h、浸提温度85℃、物料比1∶18。From the single factor test and orthogonal test, the optimum extracting conditions were obtained to extract soybean isoflavone from defatted soybean meal. This experiment provides basis for extracting soybean isoflavone of industry production, The optimal conditions were： 75% ethanol concentration, 1：18 the ratio of defatted soybean meal to solvent, 85℃ extracting temperature, and 6 hours for extracting time.
