| Abstract: | Extraction process of ursolic acid from pomegranate peel by microwave was studied.Influence factors of concentration of alcohol,microwave power,temperature,solid-liquid ratio,and microwave time of extraction were investigated.Process parameters was optimazed by orthogonal experiment and results showed that the best extraction conditions were：concentration of ethanol was 55%,microwave power was 300 W,temperature was 55 ℃,ratio of materials to solution was 1：20,microwave time was 90 s.Extraction yield of ursolic acid was 1.446 2 mg/g under the optimum conditions. |
