摘要 比较了柚皮总黄酮的超声波强化提取与乙醇回流法对柚皮总黄酮提取率的影响,结果表明:超声波强化提取率是乙醇回流法的1.5倍。通过单因素试验和正交试验确定了超声波强化提取柚皮总黄酮的最佳提取工艺条件为:乙醇浓度为70%、料液比为1∶15、超声波功率为240 W的条件下提取2 h,柚皮总黄酮的提取率为5.093%。 Total flavonoids were extracted from shaddock peel by using ultrasonic extraction method and ethanol refluxing meth- od respectively, and the impact of different extraction methods on the extraction rate of total flavonoids was studied. The result showed that the extraction rate of total flavonoids extracted by ultrasonic extraction method was 1.5 times that extracted by ethanol re- fluxing method. Through single-factor experiment and orthogonal test, the optimum ultrasonic extraction technological conditions were obtained as follows : alcohol concentration 70%, solid-liquid ratio 1 : 15, ultrasonic power 240 W, and extraction time 2 h. Un- der the above optimum conditions, the extraction rate of total flavonoids from shaddock peel reached 5.093%.
