摘  要:
采用单因素实验法,探讨了乙醇体积分数、浸提温度、浸提时间、料液比及pH五个因素对鸭血糯中总黄酮得率的影响。再通过单因素实验所确定的提取条件来设计正交实验,得到鸭血糯黄酮类化合物提取的最佳工艺条件为:浸提温度60℃、乙醇体积分数75%、浸提时间2·5h、pH2和料液比1:100(g/mL),在此条件下黄酮类化合物的得率为9·52mg/g。

摘  要:
The extraction of flavonoids from Yaxuenuo was studied by the five factors of ethanol concentration,extraction temperature and time,material/liquid ratio and pH in this article.The orthogonal experiments were followed by every single factor identified in the best conditions,the optimal conditions for extraction of flavonoids from Yaxuenuo as follows:extracting temperature 60℃,ethanol concentration 75%,material/liquid ratio 1:100 and pH 2 for an extraction duration of 2.5 h,the total flavonoids yield obtained from Yaxuenuo was 9.52mg/g.
