| Abstract: | Ethanol and water are used as the solvent to extract flavonoids from barley powder,while four factors(ethanol concentration,extraction time,extraction temperature,the ratio of barley powder and ethanol) on extraction rate of barley flavonoids are studied,so the best extraction conditions of a single factor are obtained that the ethanol concentration should be 75%,the ratio of barley powder and ethanol should be 1:15,the extraction temperature should be 40℃,the extraction time should be 1 h. |
