| Abstract: | The extraction process of flavonoids from eupatorium adenophorum spreng was studied. The quantity proportion of flavonoids extracted from eupatorium adenophorum spreng was researched. The influence of solvent such as water, ethanol（60% ）, methyl alcohol （90%） were determined. The result indicated that under the extraction condition was as follow： ethanol concentration was 60% ,the ration of solid to liquid was 1：15 ,the temperature of extraction was 80℃ ,extracting time was 2 hours,the extraction rate was 2.952% |
