| Abstract: | Objective] To study the extraction process of citrus peels by organic solvent.Method] On the basis of three single factor tests of ethanol concentration,extraction temperature and extraction time,the extraction conditions of citrus peels were optimized by response surface methodology,and the impact of the three independent variables on the extraction rate of citrus peels was studied with Box-Behnken design model.Result] The best extraction conditions were 70% of ethanol concentration,73.2℃ of extraction temperature,and 2.25 h of extraction time,under which the actual yield of flavonoids was 2.02%,very close to the theoretical value of 2.06%.Conclusion] The extraction technology of response surface methodology is reliable,providing theoretical guidance to the extraction of flavonoids from citrus peel. |
