摘要
通过乙醇浸提及正交试验探讨了从桂花中提取黄酮的最佳工艺条件。实验结果表明乙醇浓度80%,提取时间3h,固液比140,提取温度90℃时,总黄酮的提取效果最好。
The experiment extracted flavonoids through ethanol digestion and orthogonal test and studied the optimum extracting conditions of flavonoids in sweet-scented osmanthus. The results showed that the ethanol consistence 80%,extracting time 3h,ratio of solid to liquid as 1:40 and temperature of extraction 90 were the optimum extracting conditions.
