摘要:

采用超声波提取,通过L9(34)正交试验设计,探讨了提取条件对脐橙皮中黄酮提取率的影响。结果表明,脐橙皮中黄酮类化合物提取最佳的工艺条件为超声波功率为125W、乙醇体积分数为60%、料液比为1:35、超声波作用时间60min,黄酮类化合物的提取率为49.3mg/g。

Abstract:

Ultrasonic treatment was applied to the ethanol extraction of flavonoids from navel orange peel. The effects of four crucial variables such as ultrasonic power, ethanol concentration, material/liquid ratio and ultrasonic treatment time on the yield of flavonoids were investigated by single-factor method. An orthogonal array design leading to a set of 9 combinations of these variables was performed to obtain the highest yield of flavonoids. Under the optimized conditions as follows: ultrasonic power 125 W, 60% alcohol as the extraction solvent, material/liquid ratio 1: 35, and extraction time 60 min, a yield of flavonoids of 49.3 mg/g was achieved.
