摘  要:
利用超声波法提取黄树莓叶中的总黄酮,考察了超声功率、超声时间、乙醇浓度、料液比4个因素对总黄酮得率的影响,通过单因素试验和正交试验确定提取的最佳工艺条件。结果表明:黄树莓最佳提取工艺为超声波功率High档位,超声时间70min,乙醇浓度60.0%,料液比1∶25,总黄酮的得率为9.517%。该提取工艺简单、合理,可以用于测定黄树莓总黄酮的含量。

摘  要:
Total flavonoids was extracted from Raspberry by Ultrasonic Method.The effects of four factors including Ultrasonic power,ultrasonic time,ethanol concentration,solid-liquid ratio on the yield of total flavonoids were investigated.The optimum technological conditions of total flavonoids extraction were confirmed through single factor test and the orthogonal test.The optimum exaction technology conditions of cloudberry were as follows:Ultrasonic power for high stall,ultrasonic time of 70 min,60% ethanol concentrationand solid-liquid ratio of 1:25;the yield of total flavonoid was 9.517%.The extraction process was simple,reasonable,and could be used for the determining the content of total flavonoids from the raspberry.
