| Abstract: | Using alcohol refluxing method,the paper investigated the effect of ethanol concentration,ratio of solid to liquid, extraction time,extraction temperature and pH on the extraction of flavonoids used the orthogonal test to optimize the extraction process of flavonoids.The results showed that the best extraction conditions of flavonoids in the roots of ramie were as follows：ethanol concentration being 70%,solid to liquid ratio being 1∶7,the extraction time being 60 min,temperature being 90℃,and pH being 7. |
