摘要:
研究大豆异黄酮提取的最佳工艺条件及其活性。在单因素试验和L9(34)正交试验的基础上，确定乙醇-水体系提取大豆异黄酮的最佳工艺条件：乙醇浓度80%，液料比（溶剂∶原料）24∶1，提取温度50 ℃。对异黄酮分别进行清除自由基和抑菌的活性研究，结果表明：大豆异黄酮有良好的清除羟基自由基和超氧自由基的能力；对金黄色葡萄球菌、大肠杆菌及米根霉的生长有明显的抑制作用。
Abstract:
The paper mainly concerned with the extraction and activities of soybean isoflavones.On the basis of single element experiments and L9(34) orthogonal experiments,the optimum extraction conditions were obtained: ethanol concentration 80%,solvent to soybean ratio 24∶1,temperature 50 ℃.Free-radical scavenging and anti-microbial activities of soybean isoflavones were analyzed,and the conclusion revealed that soybean isoflavones possessed superoxide radical and hydroxyl radical scavenging activities and suppressed the growth of Staphylococcus aureus,E.coli and Rhizopus oryzae.
