【摘要】 研究了利用乙醇提取麦胚黄酮及利用微波辅助萃取的方法提高麦胚黄酮的提取率。结果表明:通过单因素试验和正交试验,确定乙醇提取麦胚黄酮的最佳条件为:以80%乙醇按照固液比1∶25,于80℃条件下提取2次,共5h,麦胚黄酮提取率达到80%以上。微波处理3min,提取时间较常规方法缩短一半,提取率有很大提高。更多还原

【Abstract】 The technology for extracting the total flavonoids in wheat germ with alcohol and the method for improving the extraction yield of the total flavonoids in wheat germ by means of microwave assisted extraction were studied. Through single-factor and orthogonal experiments, the optimum working conditions for extracting the total flavonoids in wheat germ with alcohol were found to be: temperature 80℃, the ratio of wheat germ to 80% alcohol 1∶25, 2 passages required, total duration 5 h. The extraction rate of the total flavonoids in wheat germ was up to 80%. Time required by microwave treatment was 3 min, a half shorter than that of the conventional method, whereas with much higher extraction yield.更多还原
