摘　　要：本次试验以蔓菁粉末作为原材料,利用超声波辅助提取法对样品进行浸提,从蔓菁粉末中提取蔓菁总黄酮,为其综合利用提供一些试验参考。结果表明,总黄酮的最佳提取条件为乙醇浓度55%、料液比1∶30、超声波提取时间30 min、超声波功率60 W,此时蔓菁样品中总黄酮的含量为0.285 mg·g^(-1)。This experiment used Brassica rapa powder as the raw material,and the sample was extracted using ultrasonic assisted extraction method to extract total flavonoids from Brassica rapa powder,providing some experimental references for its comprehensive utilization.The results showed that the optimal extraction conditions for total flavonoids were ethanol concentration of 55%,solid-liquid ratio of 1∶30,ultrasonic extraction time of 30 minutes,and ultrasonic power of 60 W.At this time,the content of total flavonoids in the Brassica rapa sample was 0.285 mg·g-1.
